      "abstract": "This paper investigates adaptive parallel simultaneous stabilization (APSS) of a set of uncertain nonlinear port‐controlled Hamiltonian (PCH) systems subject to actuator saturation and proposes a number of results on the design of the APSS controllers. First, the case of two PCH systems is studied. Using both the dissipative Hamiltonian structural and saturated actuator properties, the two systems are combined to generate an augmented PCH system, with which, some results on the control designs are then obtained. When there are external disturbances in the two systems, anH ∞ APSS controller is designed for the systems. Second, the case of more than two uncertain PCH systems subject to actuator saturation is investigated, and several new results are proposed for the APSS problem. Finally, an illustrative example is presented to show that the adaptive stabilization controllers obtained in this paper work very well. Copyright © 2013 John Wiley &amp; Sons, Ltd.",

Controller is made robust against the parametric uncertainties using neural networks. Dynamics of the the proposed novel neural network tuning law is driven by both the position and the velocity errors owing to the information preserving filtering of the Hamiltonian gradient. In addition, the PCH structure of the closed‐loop system is preserved and the controller achieves the  disturbance attenuation objective.

      "abstract": "In this paper, discrete‐time adaptive control of linearly parameterized fully actuated Port‐controlled Hamiltonian systems with parameter uncertainties in energy function is considered. A discrete‐time adaptive interconnection and damping assignment passivity‐based control (IDA‐PBC) method, utilizing the immersion and invariance (I&amp;I) approach, for the considered uncertain Hamiltonian system, is presented. A discrete‐time parameter estimator based on the immersion and invariance approach is derived to obtain an automatic tuning mechanism for the IDA‐PBC controller. The stability analysis for the estimator and the closed‐loop system is done using the Lyapunov theory. The proposed method is applied to two fully actuated physical systems and its performance is tested by simulations. Simulation results show that the proposed I&amp;I‐based adaptive IDA‐PBC controller successfully preserves the performance of the IDA‐PBC controller designed with true parameters under a large amount of uncertainty.",

      "abstract": "In this article, finite‐time boundedness (FTB) and  control are addressed for a class of port‐controlled Hamiltonian (PCH) systems with parametric perturbations. Based on adaptive state feedback control strategies, sufficient conditions are obtained for FTB of the PCH systems with parametric perturbation and external disturbances. Furthermore, another adaptive state feedback controller is applied to compensate the parameter perturbation and attenuate the external disturbances, and finite‐time  control conditions are acquired for the PCH systems with parametric perturbation and external disturbances. In addition, the FTB and finite‐time  control conditions are also given for uncertain nonlinear systems via the Hamiltonian realization method. Finally, the numerical simulations are presented to verify the feasibility of the proposed results.",

      "abstract": "Interconnection and Damping Assignment Passivity‐Based Control (IDA‐PBC) has been one of the most employed algorithms to stabilize underactuated port‐Hamiltonian systems. However, IDA‐PBC cannot handle input disturbances. Disturbances can cause a drift in the desired equilibrium and can generate unstable behaviors. In this paper, we propose to include an adaptive term to estimate the disturbance in the IDA‐PBC for underactuated mechanical systems. Under the assumption that the disturbance is composed of a finite sum of sinusoidal functions with                    unknown                    frequencies and amplitudes, we design an estimation algorithm that is based on the internal model for which we estimate, exponentially, the frequencies and the magnitudes of the disturbances. As it is typical in IDA‐PBC, we show that the desired control objective is achieved provided that the desired output is detectable.",

      "abstract": "This paper investigates the robust simultaneous stabilization (RSS) and robust adaptive simultaneous stabilization (RASS) problem for a set of port‐controlled Hamiltonian (PCH) systems. Some results for designing a family of robust simultaneous controllers with tuning parameters for such systems are proposed. Firstly, using the dissipative Hamiltonian structural properties, these systems are combined to generate an augmented PCH system, and two simultaneous stabilization controllers with parameters are designed for the systems: one is a robust controller and the other is adaptive. Secondly, an algorithm for solving the tuning parameters’ ranges of controller is proposed with symbolic computation. Finally, a numerical example is studied by applying the method obtained in this paper to a set of PCH systems with external disturbance. The effectiveness of the proposed control method is verified by simulations. Compared with conventional simultaneous stabilization control, the controller obtained in this paper not only has strong robustness for a set of systems, but also can optimize the robustness for the systems by adjusting the parameters’ values.",

Different from existing works, this paper first presents a time‐varying finite‐time stability (FTS) criterion via an L‐K functional approach, and obtains two FTS conditions by constructing specific L‐K functionals. Then, the adaptive finite‐time robust control problem is investigated for nonlinear time‐delay port‐controlled Hamiltonian (PCH) systems, and a control design procedure is presented. Finally, the effectiveness of the results is demonstrated by an illustrative example.",

      "abstract": "This paper presents an adaptive speed observer for general port‐Hamiltonian mechanical systems with non‐holonomic constraints in the presence of unknown friction forces and constant disturbances. Unlike the observers recently reported in the literature, which have been designed either under the assumptions of no friction and the absence of disturbances or for a specific class of mechanical systems with the requirement of an explicit solution of certain Partial Differential Equations (PDEs) that cannot be derived <jats:italic>a priori</jats:italic>, this observer proposes a design that obviates the solution of PDEs and ensures global convergence for general mechanical systems with k‐non‐holonomic constraints. The observer is totally constructive and given by explicit expressions. The simulation results testify to the effectiveness and the robust features of the developed observer.",

      "abstract": "Induction machines (IM) constitute a theoretically interesting and practically important class of nonlinear systems. They are frequently used as wind generators for their power/cost ratio. They are described by a fifth‐order nonlinear differential equation with two inputs and only three state variables available for measurement. The control task is further complicated by the fact that IM are subject to unknown (load) disturbances and the parameters can be of great uncertainty. One is then faced with the challenging problem of controlling a highly nonlinear system, with unknown time‐varying parameters, where the regulated output, besides being unmeasurable, is perturbed by an unknown additive signal. Passivity‐based control (PBC) is a well‐established structure‐preserving design methodology which has shown to be very powerful to design robust controllers for physical systems described by Euler‐Lagrange equations of motion. PBCs provide a natural procedure to \"shape\" the potential energy yielding controllers with a clear physical interpretation in terms of interconnection of the system with its environment and are robust vis á vis to unmodeled dissipative effects. One recent approach of PBC is the Interconnection and Damping Assignment Passivity‐Based Control (IDA‐PBC) which is a very useful technique to control nonlinear systems assigning a desired (Port‐Controlled Hamiltonian) structure to the closed‐loop. The aim of this paper is to give a survey on different PBC of IM. The originality of this work is that the author proves that the well known field oriented control of IM is a particular case of the IDA‐PBC with disturbance.",

Specifically, we prove that the reduced system, the projection matrix of which is constructed by solving specific Sylvester equations, satisfies the right (or left) tangential interpolation condition and retains the port‐Hamiltonian structure; hence it remains passive. Based on the tangential interpolation, we propose two structure‐preserving model reduction algorithms for port‐Hamiltonian systems and present several numerical examples to illustrate their effectiveness.",

      "abstract": "This paper proposed a novel disturbance observer‐based control state‐error port‐controlled Hamiltonian (DOBC‐SEPCH) control strategy for optimization of energy consumption and enhancement of tracking performance for unmanned surface vehicle (USV) with unknown environmental disturbances via the PCH system techniques. Firstly, an observer is constructed to estimate disturbances. Then, an energy‐based controller is constructed by using the SEPCH system method. In addition, the SEPCH controller provided that the tracking errors converged exponentially to zero. The SEPCH technique is augmented by a disturbance observer. Due to the controller need to be designed in two stages, the stability of the whole system will be difficult to be discussed. We give the proof of the stability of the desired target dynamic system. The robustness and control performance of the system are enhanced. The simulation and comparison results illustrate the performance of this controller.",

      "abstract": "This work integrates passivity‐based inventory control with the port‐Hamiltonian framework to design stabilizing feedback laws for lumped parameter chemically reacting systems. A static state feedback law with admissible controls is developed using an inventory‐related storage function as a closed loop Hamiltonian function. The control gain matrix is derived from the interconnection and damping matrices of the resulting Hamiltonian representation. Consequently, the proposed controller globally and exponentially stabilizes the system at a desired set‐point (including the open loop unstable equilibrium point) without restrictions on the reaction kinetics. Numerical simulations illustrate the application of the theory to a nonisothermal, continuous stirred tank reactor with the steady‐state multiplicity. The proposed approach is compared with the thermodynamic availability‐based control approach in terms of amplitude and variation rate to show its performance and effectiveness.",

      "abstract": "A novel robust state error port controlled Hamiltonian (PCH) trajectory tracking controller of an unmanned surface vessel (USV) subject to time‐varying disturbances, dynamic uncertainties and control input saturation is presented. The proposed control scheme combines the advantages of the high robustness and energy minimization of the state error PCH approach and the approximation capability of adaptive radial basis function neural networks (RBFNNs). Adaptive RBFNNs are used to the time‐varying disturbances of the environment and unknown dynamics uncertainties of the USV model. The state error PCH control approach is designed such that the system can optimize energy consumption, and the state error PCH technique makes the designed trajectory tracking controller be easy to implement in practice. To handle the effect of the control input saturation, a Gaussian error function model is employed. It has been demonstrated that the proposed approach can maintain the USV's trajectory at the desired trajectory, while the closed‐loop control system can guarantee the uniformly ultimate boundedness. The energy consumption model of the USV is constructed to reveal to the energy consumption. Simulation results demonstrate the effectiveness of the proposed controller.",

      "abstract": "The full‐order observer design problem for a particular class of port‐controlled Hamiltonian systems is approached in this paper. The proposed full‐order observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the convergence analysis and exhibits a structure that is a copy of the original system plus an output corrective term. Due to the physical interpretation of port‐controlled Hamiltonian systems, the proposed full‐order observer is attractive because the estimated states have an immediate practical meaning. The class approached in this paper considers both linear and nonlinear dissipation terms, a quadratic Hamiltonian function and internal interconnections between two components of the state vector modulated by another state component that correspond to quadratic nonlinearities. This features lead to several structural properties that allow to carry out the convergence analysis in a relatively simple way and leads to a simple tuning procedure. The usefulness of the contribution is illustrated considering two practical applications: the Lorenz oscillator and the permanent magnet synchronous motor.",

      "abstract": "This paper investigates the estimate of domain of attraction for a class of nonlinear port‐controlled Hamiltonian (PCH) systems subject to both actuator saturation and disturbances. Firstly, two conditions are established to determine whether an ellipsoid is contractively invariant for the systems only with actuator saturation, with which the biggest ellipsoid contained in the domain of attraction can be found. Secondly, the obtained conditions are extended to estimate the domain of attraction of the systems subject to both actuator saturation and disturbances. Study of illustrative example shows the effectiveness of the method proposed in this paper.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society",

      "abstract": "This article focuses on the trajectory tracking control (TTC) of autonomous underwater vehicles (AUVs) operating in three‐dimensional (3D) underwater environments with concurrent ocean disturbances, parametric uncertainties and actuator saturation constraints. A tracking control architecture integrating the state‐error port‐controlled Hamiltonian (SEPCH) energy shaping approach with radial basis function neural networks (RBFNNs) is developed to guarantee the uniform ultimate boundedness (UUB) of closed‐loop dynamics. Specifically, the Hamiltonian energy‐shaping framework is systematically synthesized to establish the intrinsic stability property, while adaptive RBFNNs compensators are designed to estimate the compounded perturbations arising from the ocean current disturbances and parameter uncertainties effects. Furthermore, the challenge caused by input saturation is tackled by means of an auxiliary system by confining the control force to certain predefined saturation bounds. Simulation examples demonstrate the validity of the proposed control method.",

Through a coordinate transformation and a passive interconnection between mechanical system and camera dynamics we realize a closed‐loop system that is port‐<jats:styled-content style=\"fixed-case\">H</jats:styled-content>amiltonian. The resulting control strategy depends only on the camera states and it can be proven that the closed‐loop system is also asymptotically stable. Furthermore, a region of attraction is defined for which asymptotic stability holds.",

      "abstract": "This paper discusses a ring‐coupled buck‐type inverter system to harness energy from direct current (DC) sources of electricity. The DC‐DC buck converter circuit is modified with an H‐bridge to convert the DC input voltage to a usable alternating current (AC) output voltage. Passivity‐based control (PBC) with port‐controlled Hamiltonian modelling (PCHM) is a method where the system is controlled by considering not only the energy properties of the system but also the inherent physical structure. PBC is applied to achieve stabilization of the AC output voltage to a desired amplitude and frequency. Unsynchronized output voltages in terms of phase angle or frequency can cause detrimental effects on the system. Phase‐locked loop (PLL) is employed in the ring structure to maintain synchronization of the AC output voltage of all inverter units in the ring‐coupled system.",

Here, we derive models as port‐Hamiltonian systems on several levels: overall systems, multiply coupled systems, and systems within dynamic iteration procedures. To this end, we introduce new classes of port‐Hamiltonian differential‐algebraic equations. Thereby, we additionally allow for nonlinear dissipation on a subspace of the state space. Both, each subsystem and the overall system possess a port‐Hamiltonian structure. A structural analysis is performed for the new setups. Dynamic iteration schemes are investigated, and we show that the Jacobi approach as well as an adapted Gauss‐Seidel approach lead to port‐Hamiltonian differential‐algebraic equations.",

      "abstract": "A controller able to achieve bidirectional power flow for a boost‐like full‐bridge rectifier is presented. It is shown that no single output yields a stable zero dynamics for power flowing both ways. The controller is computed using port Hamiltonian passivity techniques for a suitable generalized state space averaging truncation of the system, which transforms the control objectives, namely specified output mean value of the voltage dc‐bus and unity input power factor in the ac side, into a regulation problem. Simulation and experimental results for the full system confirm the correctness of the simplifications introduced to obtain the controller. Copyright © 2007 John Wiley &amp; Sons, Ltd.",

      "abstract": "An interconnection and damping assignment passivity-based (IDA-PB) control design is proposed to improve the dynamic performance of voltage source converter high-voltage direct current (VSC-HVDC) system. The port-controlled Hamiltonian with dissipation (PCHD) model for voltage source converter (VSC) is developed according to the PCHD equation, and the strict passivity of the PCHD model is proved. On the basis of the PCHD model, a desired energy function is constructed by assigning interconnection and damping matrix and used as Lyapunov function. Then the IDA-PB control is designed according to desired equilibrium point, state variables, and IDA-PB control principle. By using this type of controller, the influence of the equivalent resistance of the VSC direct current side on the VSC-HVDC system is eliminated. The effectiveness of the proposed IDA-PB control is demonstrated through simulation studies on a two-terminal VSC-HVDC system by PSCAD/EMTDC software. The simulation results show that the controller has significant contribution to improve the dynamic behavior of the VSC-HVDC system under a variety of operation conditions.

As this research field is quite rich, we restrict ourselves to the class of infinite‐dimensional linear port‐Hamiltonian systems and we will focus on topics such as well‐posedness, stability and stabilizability. We combine the  operator theoretic approach with the more physical approach based on Hamiltonians. This enables us to derive easy verifiable conditions for well‐posedness and stability.",

      "abstract": "The uniform exponential stabilities (UESs) of two hybrid control systems comprised of a wave equation and a second‐order ordinary differential equation are investigated in this study. Linear feedback law and local viscosity are considered, as are nonlinear feedback law and internal anti‐damping. The hybrid system is first reduced to a first‐order port‐Hamiltonian system with dynamical boundary conditions, and the resulting system is discretized using the average central‐difference scheme. Second, the UES of the discrete system is obtained without prior knowledge of the exponential stability of the continuous system. The frequency domain characterization of UES for a family of contractive semigroups and the discrete multiplier approach are used to validate the main conclusions. Finally, the Trotter–Kato theorem is used to perform a convergence study on the numerical approximation approach. Most notably, the exponential stability of the continuous system is derived by the convergence of energy and UES, which is a novel approach to studying the exponential stability of some complex systems. Numerical simulation is used to validate the effectiveness of the numerical approximating strategy.",

Using linearization, energy estimates, and fixed‐point arguments, we establish the existence and uniqueness of solutions that, for sufficiently small data, are global in time and converge exponentially fast to equilibrium. In contrast to previous work, our analysis is based on a velocity–enthalpy formulation of the problem, whose weak form reveals the underlying port‐Hamiltonian structure. Moreover, the weak form of the problem is particularly well suited for a structure‐preserving discretization. This is demonstrated in numerical tests, which also highlight typical characteristics of the models under consideration.",

      "abstract": "This work introduces a semi‐discrete formulation for a class of infinite‐dimensional port‐Hamiltonian systems (PHS) through a finite volume approach. After spatial discretization, the resulting models maintain the core structural properties of PHS, including the underlying Dirac structure, which is preserved in the absence of external interconnections. A key aspect of this approach involves the integration of a finite‐dimensional controller with the infinite‐dimensional system through a power‐conserving interconnection. Furthermore, we establish a criterion for the existence of discrete analogs of Casimir functions in the discretized framework. The methodology is illustrated through its application to the Timoshenko beam model, where a discrete Casimir function is effectively constructed, reflecting the essential features of the continuous case.",

      "abstract": "In this paper, we study the nearest stable matrix pair problem: given a square matrix pair (E,A), minimize the Frobenius norm of (ΔE,ΔA) such that (E+ΔE,A+ΔA) is a stable matrix pair. We propose a reformulation of the problem with a simpler feasible set by introducing dissipative Hamiltonian matrix pairs: A matrix pair (E,A) is dissipative Hamiltonian if A=(J−R)Q with skew‐symmetric J, positive semidefinite R, and an invertible Q such that QTE is positive semidefinite. This reformulation has a convex feasible domain onto which it is easy to project. This allows us to employ a fast gradient method to obtain a nearby stable approximation of a given matrix pair.",

      "abstract": "Port Hamiltonian systems formalism [1] is proposed for providing the general control theory for finite‐dimensional systems, with the models typically used in multibody dynamics (such as rigid components interconnected with flexible joints, or ports). Many present applications require better modeling of the system flexibility (and risk of damage), and one has to consider infinite‐dimensional systems. The nonlinear dynamics and control of such a system in terms of Reissner's geometrically exact beam are studied in this work. More precisely, we first present the theoretical formulation for nonlinear dynamics for a 2D Reissner's beam constructed as a port‐Hamiltonian system. This results in a highly nonlinear problem due to nonlinear beam kinematics capable of representing finite displacements, rotations, and strains. The port Hamiltonian formulation suitable for the (nonlinear) control problems is then developed by selecting appropriate effort and flow variables, and the model is reformulated as a coupled system of first‐order partial differential equations in a structure‐preserving format in a continuum setting. We then develop an expanded format required for a nonlinear system and the corresponding variational formulation by using the principle of virtual power, with the boundary conditions defining the port variables that are used in control. The final step is the finite element discretization by using finite element interpolations for such a nonlinear port‐Hamiltonian formulation, resulting in a set of nonlinear ordinary differential equations with nodal degrees that count displacements, rotation, linear and angular velocities, forces, and moments, which provides the greatest flexibility in choosing control strategies. This set of differential equations is here integrated by the backward Euler scheme, resulting in a nonlinear system of algebraic equations. The consistent linearization of such a system provides a robust performance for the proposed port Hamiltonian formulation. This is illustrated with the results of several numerical simulations that confirm the improved performance in energy conservation, which is superior to those provided previously by energy‐conserving time integration schemes that have been constructed for fully discretized problems [2].",

The presented approach is based on Port‐Hamiltonian systems and it achieves good tracking as well as good disturbance rejection based on a polynomial approach. A PBC controller stabilizes the trajectory and the feedforward part has to fulfill the given limitations and the time optimality. This approach avoids the solution of a boundary value problem and a real‐time integration of the internal dynamics. (© 2011 Wiley‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)",

For certain equilibria the definiteness requirements on the virtual energy of the port‐Hamiltonian (pH) target system and the closed loop dissipation matrix can not be satisfied simultaneously. At the GAMM Meeting 2012 we presented a modification of the nonlinear pH target system, where particularly the total energy function is augmented by a cross term between coordinates and momenta. For the sake of brevity in this short communication we focus on the case of linear mechanical systems. In particular, it is shown how the generalized pH target structure is derived from the solution of a Lyapunov equation for the closed loop system. (© 2012 Wiley‐VCH Verlag GmbH &amp; Co.

A crucial property of this system class is the property to be able to link a power balance relation to the structure of the equations. However, one has to take into account also the effects of energy flows via the boundary. This is straightforward when the Hamiltonian depends on derivative variables of first order, e.g. by using integration by parts. If second‐order derivatives appear then integration by parts cannot be used without due care, thus we suggest an approach by using the so‐called Cartan‐form. We visualize the derivation of a power balance relation by using the Kirchhoff plate as an example. (© 2016 Wiley‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)",

      "abstract": "Port‐based network modeling of multi‐physics problems leads naturally to a formulation as port‐Hamiltonian differential‐algebraic systems (pHDAEs). In this way, the physical properties are directly encoded in the structure of the model. Since the state space dimension of such systems may be very large, in particular when the model is a space‐discretized partial differential‐algebraic system, in optimization and control there is a need for model reduction methods that preserve the port‐Hamiltonian (pH) structure while keeping the algebraic constraints unchanged. To combine model reduction for differential‐algebraic equations (DEAs) with port‐Hamiltonian structure preservation, we adapt power conservation based techniques from port‐Hamiltonian systems of ordinary differential equations (pHODEs) to pHDAEs. The performance of the methods is investigated for benchmark examples originating from semi‐discretized flow problems.",

Especially when the application of model reduction is desirable, systematic and rather generic approaches are of great interest. In this contribution we discuss a structure‐preserving Galerkin approach for a prototypical class of nonlinear partial differential equations on networks. Its derivation is guided by port‐Hamiltonian‐type modeling and appropriate variational principles. Also complexity‐reduction schemes can be integrated in a structure‐preserving way, which becomes crucial in the context of model reduction for nonlinear systems.",

In this context we consider the non‐isothermal flow of a compressible fluid. Starting from the pdes we derive a pH formulation for Euler‐type equations in the weak sense on one pipe. One advantage of pH systems is that fundamental physical properties, like energy dissipation and mass conservation, are encoded in the system structure. Therefore, structure‐preservation during approximation is most important. Based on the weak form we introduce a structure‐preserving Galerkin approximation with mixed finite elements. A numerical example supports the theoretical results.",

In the pH‐framework physical properties, like mass conservation and energy dissipation, are encoded in the system structure. Applying a structure‐preserving Galerkin approximation with mixed finite elements in space yields a nonlinear system with state‐dependent matrices. Assembly of these matrices in each time step is computationally expensive and makes model reduction inefficient, since the nonlinearities still depend on the full order state. We investigate the use of the extended group finite element method (EGFEM) to efficiently handle pH structure‐preservation. EGFEM separates the systems matrices into products of a state‐independent (precomputable) tensor and a state‐dependent vector for the nonlinearities, making the system easily accessible for complexity reduction.",

The emancipation from producing countries alongside the renewable energy transition increases the number of scenarios to be simulated manifold, which in turn requires the acceleration of computational models to ensure completion of computer simulations before deadlines.Gas is transported through a network of pipelines which can be mathematically modeled as large‐scale nonlinear port‐Hamiltonian input‐output systems. To reduce computational complexity we propose unsupervised learning via synthetic data of the model's system‐theoretic properties which then enables data‐driven control or model reduction.We summarize the aspects of nonlinear model reduction techniques adapted to gas pipeline networks and orchestrated to reduce the order of this challenging class of systems originating from hyperbolic systems of partial differential‐algebraic equations, and demonstrate the applicability of our approach numerically.",

The first‐order optimality system for the port‐Hamiltonian system‐constrained optimal control problem is formally derived. Then we propose a gradient‐based algorithm to find optimal controls. The port‐Hamiltonian system formulation naturally conserves flow and supports a wide array of further modeling options as, for example, node reservoirs, flow dependent costs, leaking pipes (dissipation) and coupled sub‐networks (ports). They thus provide a versatile alternative to state‐of‐the art approaches towards dynamic network flow problems, which are often based on computationally costly time‐expanded networks. We argue that this opens the door for a plethora of modeling options and solution approaches for network flow problems.",

      "abstract": "The port‐Hamiltonian (pH) formulation of partial‐differential equations and their numerical treatment have been elaborately studied lately. One advantage of pH‐systems is that fundamental physical properties, like energy dissipation and mass conservation, are encoded in the system structure. Therefore, structure‐preservation is most important during all stages of approximation and system coupling. In this context we consider the non‐isothermal flow of a compressible fluid through a network of pipes. Based on a pH‐formulation of Euler‐type equations on one pipe, we introduce coupling conditions, through which we can realize energy, mass and entropy conservation at the coupling nodes and thus, preserve the pH‐structure. We implement them through an input‐output‐coupling using the flow and effort variables of the boundary port. Thus, we can make use of the structure‐preserving model and complexity reduction techniques for the single pipe. This procedure becomes even more important for network simulations, as here, we deal with high dimensional and highly non‐linear dynamical systems. We explain the extension from a single pipe to a network and numerical examples are shown to support our findings.",

The governing equations are obtained in a variational manner and represent index‐1 differential algebraic equations. Performing an index reduction, one obtains the port‐Hamiltonian state space model, which features the nonlinear strains as an independent state next to position and velocity. Moreover, hyperelastic material behavior is captured in terms of a nonlinear stored energy function. The model exhibits passivity and losslessness and has an underlying symmetry yielding the conservation of angular momentum. We perform temporal discretization using the midpoint discrete gradient, such that the beneficial properties are inherited by the developed time stepping scheme in a discrete sense. The numerical results obtained in a representative example are demonstrated to validate the findings.",

We investigate the robustness of different stage‐cost designs w.r.t. time discretization and show that alternative formulations that are equivalent in continuous time, differ strongly in view of discretization. Furthermore, we consider the impact of additional quadratic control regularization and demonstrate that this leads to a considerable increase in energy consumption. Then, we extend our results to the tracking problem within model predictive control and show that the intrinsic but singular choice of the cost functional as the supplied energy leads to a substantial improvement of the closed‐loop performance.",

That means no energy can be generated within the system. A passive system cannot store more energy than it receives. The exact solution of the pH system hence fulfills the dissipation inequality. In this paper, we deal with operator splitting that considers the energy‐conserving and dissipative parts separately. We aim at high‐order splitting schemes that preserve the dissipation inequality. Fourth‐order methods for linear pH systems are derived and an extension to sixth‐order methods is discussed.",

      "abstract": "Control engineering applications usually require a model that accurately represents the dynamics of the system. In addition to classical physical modeling, powerful data‐driven approaches are gaining popularity. However, the resulting models may not be ideal for control design due to their black‐box structure, which inherently limits interpretability. Formulating the system dynamics in port‐Hamiltonian form is highly beneficial, as its valuable property of passivity enables the straightforward design of globally stable controllers while ensuring physical interpretability. In a recently published article, we presented a method for data‐driven inference of port‐Hamiltonian models for complex mechatronic systems, requiring only fundamental physical prior knowledge. The resulting models accurately represent the nonlinear dynamics of the considered systems and are physically interpretable. In this contribution, we advance our previous work by including two key elements. Firstly, we demonstrate the application of the above described data‐driven PCHD models for controller design. Preserving the port‐Hamiltonian form in the closed loop not only guarantees global stability and robustness but also ensures desired speed and damping characteristics. Since control systems based on output measurements, which are continuously measured during operation due to the feedback structure, we secondly aim to use this data. Thus, we augment the existing modeling strategy with an intelligent adaptation approach to address uncertainties and (un)predictable system changes in mechatronic systems throughout their lifecycle, such as the installation of new components, wear, or temperature fluctuations during operation. Our proposed algorithm for recursively calculated data‐driven port‐Hamiltonian models utilizes a least‐squares approach with extensions such as automatically adjusting the forgetting factor and controlling the covariance matrix trace. We demonstrate the results through model‐based application on an academic example and experimental validation on a test bench.",

Models used in these simulations require a detailed framework integrating various models of the network constituents ‐ pipes and compressor stations among others. In this context, the port‐Hamiltonian modelling framework provides an energy‐based modelling approach with a port‐based coupling mechanism. This study investigates developing compressor models in an integrated isothermal port‐Hamiltonian model for gas networks. Four different models of compressors are considered and their inclusion in a larger network model is detailed. A numerical implementation for a simple test case is provided to confirm the validity of the proposed model and to highlight their differences.",

Classical high‐order splitting schemes possess negative step sizes, which might cause instabilities and the violation of the dissipation inequality. Negative step sizes can be avoided by using commutator‐based methods. Structure‐preservation depends then crucially on the properties of the designed commutator. For an energy‐associated decomposition, we exploit the skew‐symmetry of a third‐order commutator in the linear case and discuss generalizations for nonlinear systems, such as conformal Hamiltonian systems. We derive structure‐preserving splitting schemes of up to fourth order.",

      "abstract": "In this work, we present a structure‐preserving Krylov subspace iteration scheme for solving the equation systems that arise from the Gauss integration of linear energy‐conserving and dissipative differential systems (e.g., Poisson systems, gradient systems, and port‐Hamiltonian systems). Exploiting the relation between Gauss integrators and diagonal Padé approximations, the ‐Arnoldi process yields iterates that are not only energy‐preserving up to convergence but also on each iteration level. We extend the approach to cover also energy dissipation. The use of the ‐Arnoldi approximation for Gauss integration enhances the computational efficiency as it allows a termination of the iteration without loss of energy‐associated structures as soon as the desired accuracy of the numerical integrator is reached. We investigate the performance in splitting schemes for linear port‐Hamiltonian systems.",

The airship is modelled as an eudipleural submerged rigid body whose dynamics is formulated as a Hamiltonian system with respect to a Lie–Poisson structure. By exploiting the geometrical structure and using the so‐called interconnection and damping assignment (IDA) passivity‐based methodology for port‐controlled Hamiltonian systems, state feedback control laws asymptotically stabilizing two typical motions are designedviaLa Salle invariance principle and Chetaev instability theorem.

      "abstract": "A solution to the stabilization problem of a compact set by means of the Interconnection and Damping Assignment Passivity‐Based Control methodology, for an affine nonlinear system, was introduced. To this end, we expressed the closed‐loop system as a Port Hamiltonian system, having the property of almost all their trajectories asymptotically converge to a convenient limit set, except for a set of measure zero. It was carried out by solving a partial differential equation (PDE) or single matching condition, which allows the desired energy level or limit set <jats:italic>E</jats:italic> to be shaped explicitly. The control strategy was tested using the magnetic beam balance system and the pendulum actuated by a direct current motor (DC‐motor), having obtained satisfactory results.

      "abstract": "This paper presents the results of formation keeping control of a group of nonholonomic wheeled robots within the port‐Hamiltonian framework and in the presence of matched input disturbances. Two scenarios on the internal damping of the dynamics of the robots are considered: strictly output passive and loss less robots. For strictly output passive robots, the distributed formation keeping controllers drive the robots towards a desired formation, while internal‐model‐based controllers locally compensate the harmonic input disturbance for each of the robots. Moreover, the effect of constant input disturbances is studied considering internal‐model‐based controllers. For lossless robots, results on formation keeping control are presented. Simulation results illustrate the effectiveness of the approach. Copyright © 2016 John Wiley & Sons, Ltd.",

We clarify necessary conditions for the closed‐loop system of an SPHS to be SISS. Moreover, we provide a systematic construction of both the SISS controller and Lyapunov function so that the proposed necessary conditions hold. In the main results, the stochastic generalized canonical transformation plays a key role. The stochastic generalized canonical transformation technique enables to design both coordinate transformation and feedback controller with preserving the SPHS structure of the closed‐loop system. Consequently, the main theorem guarantees that the closed‐loop system obtained by the proposed method is SISS against both deterministic disturbance and stochastic noise.

      "abstract": "This article proposes a global continuous robust finite‐time control (GCRFTC) for a unified power flow controller (UPFC) to improve the transient stability and oscillation damping of power system. First, by using an appropriate coordinate transformation, the nonlinear system of the UPFC is transformed into a nonlinear port‐controlled dissipative Hamiltonian (PCDH) system. Second, based on the PCDH system, by utilizing the Hamiltonian structural properties and the “energy shaping plus damping injection” technique, a proper form of a Hamiltonian function is obtained for the PCDH system. Third, using the Hamiltonian function method, finite‐time stability criterion and robust control technique, the GCRFTC is designed and theoretically proved, and the chattering phenomena and the high‐order frequencies of the power system are avoided effectively. Lastly, a six‐bus and two power plants power system with a UPFC is used to test the effectiveness and robustness of the GCRFTC. Simulation results show that the speed, overshoot, and settling time of the response and the transient conditions of the GCRFTC are further improved in comparison with that of the robust finite‐time power flow control.",

      "abstract": "Using a structure preserving observer, a dynamic output controller is proposed for a class of port‐Hamiltonian systems. The core of this method is based on the notion of contractive port‐Hamiltonian systems. The proposed method utilizes an extended form of IDA‐PBC (interconnection and damping assignment passivity‐based control), a well‐known controller design method for port‐Hamiltonian systems and paves the way for using IDA‐PBC in output control design of challenging control objectives, such as output tracking for underactuated mechanical systems. In the line of output control design, a useful separation principle for a class of port‐Hamiltonian systems is achieved, which is valuable in the field of nonlinear systems. Some simulations on magnetic levitation and ball on wheel testbeds show the potency and applicability of the proposed method.",

      "abstract": "In this work, we present a constructive method to design a family of virtual contraction based controllers that solve the standard trajectory tracking problem of flexible‐joint robots in the port‐Hamiltonian framework. The proposed design method, called virtual contraction based control, combines the concepts of virtual control systems and contraction analysis. It is shown that under potential energy matching conditions, the closed‐loop virtual system is contractive and exponential convergence to a predefined trajectory is guaranteed. Moreover, the closed‐loop virtual system exhibits properties such as structure preservation, differential passivity, and the existence of (incrementally) passive maps. The method is later applied to a planar RR robot, and two nonlinear tracking control schemes in the developed controllers family are designed using different contraction analysis approaches. Experiments confirm the theoretical results for each controller.",

      "abstract": "This article investigates the control problem for underactuated port‐controlled Hamiltonian systems with multiple linearly parameterized additive disturbances including matched, unmatched, constant, and state‐dependent components. The notion of algebraic solution of the matching equations is employed to design an extension of the interconnection and damping assignment passivity‐based control methodology that does not rely on the solution of partial differential equations. The result is a dynamic state‐feedback that includes a disturbance compensation term, where the unknown parameters are estimated adaptively. A simplified implementation of the proposed approach for underactuated mechanical systems is detailed. The effectiveness of the controller is demonstrated with numerical simulations for the magnetic‐levitated‐ball system and for the ball‐on‐beam system.",

      "abstract": "This article investigates the output regulation for stochastic port‐Hamiltonian systems (SPHSs) subject to sinusoidal disturbances. An energy‐based regulation scheme with an internal model unit is proposed by exploiting the stochastic Hamiltonian structure, which drives the tracking error to the origin while maintaining asymptotical stability in probability of the closed‐loop system. An energy‐based robust regulation scheme as well as an alternative condition is then developed without solving Hamilton–Jacobi–Issacs inequalities. The proposed regulators preserve the stochastic Hamiltonian structure of the disturbed SPHS by coordinate transformation. Hence the output regulation problems fall into the stabilization framework for SPHSs and there is no need to solve regulator equations. These results cover the stabilization of SPHSs and the output regulation of deterministic port‐Hamiltonian systems. Simulations on an inverted pendulum show the effectiveness of the proposed methods.",

      "abstract": "A nonlinear observer design approach is proposed that exploits and combines port‐Hamiltonian systems and dissipativity theory. First, a passivity‐based observer design using interconnection and damping assignment for time variant state affine systems is presented by applying output injection to the system such that the observer error dynamics takes a port‐Hamiltonian structure. The stability of the observer error system is assured by exploiting its passivity properties. Second, this setup is extended to develop an observer design approach for a class of systems with a time varying state affine forward and a nonlinear feedback contribution. For a class of nonlinear systems, the theory of dissipative observers is adapted and combined with the results for the passivity‐based observer design using interconnection and damping assignment. The convergence of the compound observer design is determined by a linear matrix inequality. The performance of both observer approaches is analyzed in simulation examples.",

      "abstract": "In this article we consider the general problem of how to properly endow a stochastic port‐Hamiltonian system (SPHS) with an energy tank, that is an energy reservoir that allows to guarantee the passivity property. We show that a stochastic bilateral teleoperation system, composed by a master robot and a slave robot modeled as SPHS, can be connected in a power‐preserving manner to energy tanks. The stored energy is continuously monitored to keep the system passive despite time‐varying communication delays and interaction with unknown environment that may destabilize the overall system. We will address latter problem considering a SPHS affected by a noise composed by a linear, multiplicative component in Itô form plus an additive one. We underline that such a scenario requires the introduction of an <jats:italic>ad hoc</jats:italic> notion of passivity.",

      "abstract": "In this article, we propose a novel interconnection and damping assignment passivity‐based control (IDA‐PBC) design for a quarter car nonlinear active suspension system. As an energy shaping method, IDA‐PBC is suitable for applying the main concept of skyhook (SH) control. In addition to the damping term, we utilize the characteristics of the energy shaping method to change the sprung and unsprung masses, thereby strengthening the vibration suppression effect. An IDA‐PBC‐based controller design for an active suspension system, which includes a nonlinear spring, a nonlinear damper, and mass uncertainty, is proposed. Different from most IDA‐PBC applications, which tend to control the position or the velocity, our methods focus on transforming a nonlinear suspension system into a desired linear system with ideal aseismatic properties. Unlike a conventional controller using the SH control strategy, we design a virtual vehicle body and an unsprung mass in addition to the damper coefficients. By deriving the port‐Hamiltonian form of the suspension system from its dynamics and rewriting it based on the relative coordinates, we obtain a feedback law that only uses the relative displacement and velocity of the suspension system. We derive the conditions for ensuring the global asymptotical stability of the suspension system and propose the guidelines for parameter selection that can guarantee robust stability against parameter uncertainties.",

      "abstract": "This work investigates the energy shaping control of a class of underactuated mechanical systems with first‐order actuator dynamics and subject to both matched and unmatched constant additive disturbances. To this end, a new nonlinear control law which includes two independent integral actions is presented. The controller design is outlined for systems with first‐order actuator dynamics, and also for systems with direct actuation. The effectiveness of the proposed approach is demonstrated with numerical simulations on an inertia wheel pendulum and on a ball‐on‐beam system, both actuated by electric DC motors and subject to constant disturbances.",

      "abstract": "Practical circuit systems frequently suffer from noise and unknown loads, which are prevalent industrial phenomena. This paper addresses these challenges by proposing a systematic estimator design methodology and an adaptive proportional‐integral (PI) control strategy for stochastic port‐Hamiltonian systems (SPHSs) with unknown loads. The state‐dependent nature of multiplicative noise fundamentally disrupts conventional passivity‐based control approaches for SPHSs, necessitating both a reconstructed passivity framework and innovative control architecture. We develop stochastic passivity theory via infinitesimal generator analysis for systems with measurable states, which enables PI control implementation under constant passivation conditions. For SPHSs where standard passivity theory becomes inapplicable due to unknown loads, we propose specialized estimators for real‐time parameter identification and a corresponding adaptive PI control scheme with guaranteed stability. Experimental validation through comprehensive simulations on a three‐phase rectifier system with multiplicative noise confirms the framework's effectiveness.",

      "abstract": "To improve the disadvantages of signal control and energy control, a cooperative control strategy combining signal control and energy control is proposed for manipulators driven by permanent magnet synchronous motors (PMSMs) in this article. The cooperative control strategy is achieved by way of the convex combination of signal controller and energy controller, and Gaussian function is selected as cooperative function. The energy controller applies variable damping error port Hamiltonian and the signal controller uses backstepping nonsingular terminal sliding mode control. The PMSM with loss model is applied to obtain higher efficiency. To deal with modeling errors and joint friction, a nonlinear disturbance observer is used for manipulators system. Simulation and experiment results display that the designed strategy not only increases efficiency, but also enhances dynamic and steady‐state performance of manipulators.",

      "abstract": "This work investigates the passivity‐based control of a class of underactuated mechanical systems subject to constant matched and unmatched disturbances, for which the momenta are not measured. The main contribution is a new design of the integral interconnection‐and‐damping assignment passivity‐based control that only relies on position feedback. Numerical simulations on a disk‐on‐disk system, on an Acrobot system, and on a rigid‐link model representative of a soft continuum manipulator demonstrate the effectiveness of the new controller.",

      "abstract": "This paper presents a co‐ordinatedH∞controller design of excitation and governor of hydroturbo‐generator sets, which is on the basis of the port‐controlled Hamiltonian (PCH) method. Firstly, the dissipative Hamiltonian realization is achieved via static state feedback, and sequentially the Hamiltonian controller is obtained based on the theory of PCH system with dissipation. Such control strategies fully consider the inherent nonlinearities and non‐minimum phase characteristic of the system dynamics, including the rigid water‐hammer phenomenon. Furthermore, the property of disturbance attenuation of this controller is revealed in the sense ofH∞. The selection of the disturbance attenuation level and the corresponding feedback gain is discussed as well. Then the effects of control input constraints are analysed, sequentially, applied to design the co‐ordinatedH∞saturating control of the considered system. Finally, digital simulations that performed on a one‐machine, infinite‐bus (OMIB) system have verified the effectiveness of the proposed co‐ordinated controllers.

We extend the conventional result of the asymptotic force regulation based on the energy shaping method for a port‐Hamiltonian system. Additionally, we add an extra compensator and equip a modified integrator dynamics to the proposed controller in order to introduce sufficient degrees of freedom. Those degrees of freedom enable dealing with a wider class of disturbances, which are possibly time‐varying and appear in the dynamics of all the variables of the closed‐loop system. Moreover, first, we prove that the proposed controller achieves asymptotic force regulation at the desired position without disturbances. Second, we prove that the closed‐loop system with the proposed controller becomes input‐to‐state stable with respect to any bounded disturbances and guarantees that both the solution of the system and resultant interaction force remain bounded.",

      "abstract": "A novel nonlinear energy‐based excitation controlling strategy for variable‐speed doubly‐fed induction wind generator (DFIWG) is proposed in this paper. From the consideration of physical nature and energy flow of the DFIWG, the mechanical subsystem and the electromagnetical subsystem of the DFIWG first have their port‐controlled Hamiltonian (PCH) realization. Then taking advantage of the feedback interconnection between the subsystems, the entire PCH model of the DFIWG is established. On the basis of this model, the excitation control for the generator speed adjustment is achieved by energy shaping design with the purpose of optimum wind energy capture. Finally, simulation results via MATLAB/Simulink (MathWorks, Natick, MA, USA) confirm the effectiveness of the proposed approach for wind speeds in different operating stages.

      "abstract": "In this chapter we provide a solution to the long-standing problem of transient stabilization of multimachine power systems with nonnegligible transfer conductances. More specifically, we consider the full 3 n -dimensional model of the n -generator system with lossy transmission lines and loads and prove the existence of a nonlinear static state feedback law for the generator excitation field that ensures asymptotic stability of the operating point with a well-defined estimate of the domain of attraction provided by a bona fide Lyapunov function. To design the control law we apply the recently introduced interconnection and damping assignment passivity-based control methodology that endows the closed-loop system with a port-controlled Hamiltonian structure with desired total energy function. The latter consists of terms akin to kinetic and potential energies, thus has a clear physical interpretation. Our derivations underscore the deleterious effects of resistive elements that, as is well known, hamper the assignment of simple “gradient” energy functions and compel us to include nonstandard cross terms. A key step in the construction is the modification of the energy transfer between the electrical and the mechanical parts of the system, which is obtained via the introduction of state-modulated interconnections.",

      "abstract": "Passivity-based control (PBC) for regulation of mechanical systems is a well established tehcnique that yields robust controllers that have a clear physical interpretation in terms of interconnection of the system with its environment. In particular, the total energy of the closed-loop is the difference between the energy of the system and the energy supplied by the controller. Furthermore, since the Euler-Lagrange (EL) structure is preserved in closed-loop, PBC is robustly stable vis á vis unmodeled dissipative effects and inherits some robust performance measures from its inverse optimality. Unfortunately, these nice properties are lost when PBC is used in other applications, for instance, in electrical and electromechanical systems. Our main objective in this paper is to develop a new PBC theory for port-controlled Hamiltonian (PCH) systems, which result from the network modeling of energy-conserving lumped-parameter physical systems with independent storage elements, and strictly contain the class of EL models. We identify a class of PCH models for which PBC ensures the Hamiltonian structure is preserved, with storage function the energy balance. One final advantage of the method is that it is rather systematic and the controller can be easily derived using symbolic computation",

These systems are geometrically defined by a state space manifold of energy variables, a power-conserving interconnection formalized as a Dirac structure, together with the total stored energy and a resistive structure. Basic features of these systems include their compositionality properties (a power-conserving interconnection of PCH systems is again a PCH system), and their stability and stabilizability properties exploiting the energy function and the Casimir functions. In the present paper we further elaborate on the compositionality properties of Dirac structures by providing an explicit parametrization of all achievable closed-loop Dirac structures in terms of their constituent parts. Amongst others this opens up the way to a complete characterization of the class of PCH systems which are stabilizable by interconnection with a PCH controller.",

      "abstract": "A methodology to design linear proportional–integral (PI) controllers used in power converter applications and ensuring asymptotic stability was proposed. The technique relied on the basic fact that if an affine system can be rendered passive with a constant control, then it is stabilisable with a PI. A structural condition was imposed then on the power converter to satisfy the former property with a passive output generated as a linear combination of the states. This condition is technical and has no clear physical interpretation. This result is extended in three directions: first, the aforementioned condition is removed; second, a larger class of converters (with switching external sources) is considered; third, the load resistance is assumed unknown, and an adaptive PI controller (with three different estimators) is proposed. The methodology is applied to the problem of power factor compensation of a three-phase voltage source rectifier, with simulation results presented and discussed. Also, a stable adaptive PI is designed for the output voltage regulation of a quadratic boost converter showing the performance by means of experimental result.",

The approach forms an alternative to the switched Lagrangian and (port-)Hamiltonian formulations. The proposed methodology allows for the inclusion of often encountered devices like diodes, nonlinear (multi-port) resistors, and equivalent series resistors, a feature that does not seem feasible in the switched Lagrangian formulation. Additionally, and besides the fact that the BM equations allow for almost any type of nonlinear resistor, the framework constitutes a practical advantage since in most control applications the usual measured quantities are voltages and currents—instead of fluxes and charges as with the Lagrangian or (port-)Hamiltonian approaches. The application of the proposed framework to stability analysis, new passivity properties and control is briefly highlighted.",

Firstly, we shall recall three different definitions of systems obtained by an energy based modeling: controlled Lagrangian, input-output Hamiltonian systems and port controlled Hamiltonian systems. We shall illustrate and compare these definitions on some very simple examples. Secondly we shall treat a class of systems which gave rise to numerous stabilizing control using passivity theory and corresponds to models of robotic manipulators. In each worked case we show how the main functions associated to a dissipative system (the available storage, the required supply, storage functions) can be computed analytically and related to the energy of the physical system.",

The starting point is energy and the assumption that a system can be represented by a proper interconnection. The interconnection or, better, the interaction between physical systems can be described in terms of power exchange through power ports. The proposed approach to the problem solution is based on generalization of Tellegen’s theorem well known from electrical engineering. Consequently, mathematically as well as physically correct results are obtained. The contribution is mainly concerned with presentation of a new structural approach to analysis and synthesis of linear and nonlinear causal systems. It has been proven that complete analysis of system behavior reduces to two independent tests: the monotonicity test of abstract state space energy and that of complete state observability, eventually of its dual, i.e., complete state controllability property. For comparison, the example of port-Hamiltonian approach is also presented.",

First, we shall recall three different definitions of systems obtained by an energy based modeling: controlled Lagrangian, input-output Hamiltonian systems and port controlled Hamiltonian systems. We shall illustrate and compare these definitions on some very simple examples. Second we shall treat a class of systems which gave rise to numerous stabilizing control using passivity theory and corresponds to models of robotic manipulators.

Recently, it has become known that some underactuated mechanical systems, i.e. systems with less degrees of freedom than the number of generalized coordinates, can be controlled in this frame-work [2, 3]. This control method is practicable since it is expected that passivity will provide the robust stable closed loop [4, 5]. However, addressing the subject of underactuated manipulator, there is only an application to Acrobot [6].",

These systems are defined as ordinary Hamiltonian input-output systems on a symplectic manifold, with the special property that the Hamiltonian is homogeneous in the generalized momentum variables, and that there is an invariant homogeneous Lagrangian submanifold characterizing the state properties of the thermodynamic system. After recalling the basic framework we study the passivity, controllability and observability properties of such systems.",

      "abstract": "This paper proposes a numerical investigation of a controlled loudspeaker designed to absorb acoustic plane waves at a duct termination. More precisely, a nonlinear control for a current-driven loudspeaker is presented, that relies on (1) measurements of velocity and acoustic pressure at the membrane, (2) a linear electroacoustic loudspeaker model and (3) a nonlinear finite-time control method. Numerical tests are carried out by a passive-guaranteed simulation of the loudspeaker dynamics in the port-Hamiltonian systems formalism. The sound absorption efficiency is evaluated up to 300 Hz by computing the reflected pressure at the membrane. The results are compared with a similar control architecture: the finite-time control for sound absorption proves effective, especially in the low frequency range.",

District heating network By introducing a model hierarchy of flow equations on the network, this work aims at a thermodynamically consistent port-Hamiltonian embedding of the partial differential-algebraic systems. We show that a spatially discretized network model describing the advection of the internal energy density with respect to an underlying incompressible stationary Euler-type hydrodynamics can be considered as a parameter-dependent finite-dimensional port-Hamiltonian system. Port-Hamiltonian system Moreover, we present an infinite-dimensional port-Hamiltonian formulation for a compressible instationary thermodynamic fluid flow Thermodynamic fluid flow in a pipe. Based on these first promising results, we raise open questions and point out research perspectives concerning structure-preserving discretization, model reduction, and optimization.",

      "abstract": "The boom systems of mobile cranes and aerial platform vehicles can be described as hydraulic actuated long boom manipulators. The purpose of this paper is to develop a complete mathematical model for such a boom system which is a multi-domains system consisting of the boom structure and hydraulic drive system. The hydraulic system and the boom structure are described in the port-Hamiltonian formulation. The port-Hamiltonian systems can be easily interconnected through energy exchanges, thus allowing the description of a complex system as a composition of subsystems. The structure of the long boom manipulator is specified as two main types, telescopic boom, and folding boom. These two boom types are correspondingly simplified as rotational non-homogeneous Timoshenko beam and double rotational Timoshenko beams. A structure-preserving discretization for the Timoshenko beam model is applied to transfer the boom model from infinite into finite. Then the interconnections between the hydraulic model and discretized boom structure model are illustrated and simulations of two types of long boom manipulators are accomplished in MATLAB/Simulink.",

      "abstract": "In this paper, we provide an overview of some control synthesis methodologies for boundary control systems (BCS) in port-Hamiltonian form. At first, it is shown how to design a state-feedback control action able to shape the energy function to move its minimum at the desired equilibrium, and how to achieve asymptotic stability via damping injection. Secondly, general conditions that a linear regulator has to satisfy to have a well-posed and exponentially stable closed-loop system are presented. This second methodology is illustrated with reference to two specific stabilisation scenarios, namely when the plant is in impedance or in scattering form. It is also shown how these techniques can be employed in the analysis of more general systems described by coupled PDEs and ODEs. As an example, the repetitive control scheme is studied, and conditions to have asymptotic tracking of generic periodic reference signals are presented.",

      "abstract": "The information is transmitted in neurons through axons, many of whom have myelin-covered sections, whose main purpose is to increase the speed of electrical signal transmission. Modeling the myelinated axons in a realistic way, by maintaining the physical meaning of components may lead to complex systems, described by high-dimensional systems of PDEs, whose solution is computationally demanding. Analysis of larger neuronal circuits including multiple myelinated axons therefore requires the generation of equivalent low-order models to control complexity. Such models must preserve the physical interpretation and properties of the original system including its passivity and stability. The axons’ port-based structure makes them suitable to be modeled as port-Hamiltonian systems. This paper uses a structure-preserving reduction method for port-Hamiltonian systems to reduce the description of a myelinated compartment into a model with comparable accuracy with the previously used vector fitting technique. The reduced system is synthesized into an equivalent passive circuit with no controlled sources and only positive elements, amenable for inclusion in standard neuronal simulators.",

This method was successfully used for ordinary and partial differential equations (ODEs and PDEs). In constrained dynamical problems as electric circuits or energy transport networks, differential-algebraic equations (DAEs) arise. The constraints prevent a simple transfer of operator splitting from ODEs to DAEs. Here, we present an approach for splitting linear circuit DAEs of index 1 based on a port-Hamiltonian modeling that we derive from loop and cutset equations by a topological decoupling. Finally, we present convergence results for the proposed DAE operator splitting.",

Based on a Port-Hamiltonian representation of a differential robot, canonical transformations are used to obtain a controller that guarantees the tracking of a reference. The control law is inspired by a well-known controller taken from the literature and the Port-Hamiltonian version of the control law is derived. The performance of the algorithm as well as some of the robustness properties are tested using simulations under different scenarios.",

      "abstract": "In this chapter we give an overview on energy shaping control for Distributed Parameter Systems defined on a 1D spatial domain using the port Hamiltonian framework. We consider two different cases: when actuators and sensors are located within the spatial domain and when the actuator is situated at the boundary of the spatial domain, leading to a boundary control system (BCS). In the first case we show how dynamic extensions and structural invariants can be used to change the internal properties of the system when the system is fully actuated, and how it can be done in an approximate way when the system is actuated using piecewise continuous actuators stemming from the use of patches. Asymptotic stability is achieved using damping injection. In the boundary controlled case we show how the closed loop energy function can be partially shaped, modifying the minimum and a part of the shape of this function and how damping injection can be used to guarantee asymptotic convergence.",

We are able to take advantage of underlying structural features of the system in a way that preserves them in the reduced model, using approaches that incorporate regularization and a prudent selection of interpolation data. We focus on linear time-invariant systems and present a systematic treatment of a variety of model classes that include combinations of index-1 and index-2 systems, describing in particular how constraints may be represented in the transfer function so that the polynomial part can be preserved with interpolatory methods. We propose an algorithm to generate effective interpolatory models and illustrate its effectiveness on a numerical example.",

This energy-based formulation encodes physical principles in the system structure and the pH-character is inherited during coupling. Considering a non-isothermal compressible fluid flow in a pipe, we propose a pH-model on PDE-level, which is advantageous for structure-preserving approximations. Based on Galerkin projection with compatible finite dimensional spaces we preserve the pH-structure during space discretization and model reduction. Numerical results support our theoretical findings.",

However, the underlying mathematical coupling structures have not been thoroughly investigated. In a previous work, we successfully modelled a simplified version of this problem as an infinite-dimensional system. Here, we construct a spatial discretization for the above problem and investigate its properties. We show that the discrete system is less restrictive than the original infinite-dimensional system, suggesting something like a regularization effect due to discretization.",

The construction is based on controllable and observable normal form Hamiltonian representations for those systems, which reveal fundamental relationships between classical notions in control theory and crucial properties in the machine learning context, like structure-preservation and expressive power. The results in the paper suggest parametrizations of the estimation problem associated with these systems that amount, at least in the canonical case, to unique identification and prove that the parameter complexity necessary for the replication of the dynamics is only $$\\mathcal {O}(n)$$ O ( n ) and not $$\\mathcal {O}(n^2)$$ O ( n 2 ) , as suggested by the standard parametrization of these systems.",

We suggest two Hamiltonians for the model, one based on the probability of presence and the other on the energy of the quantum system in a time-independent potential. In order to simulate the evolution of the quantum system, we adapt the model to a bounded domain. The model is discretized thanks to the structure-preserving Partitioned Finite Element Method (PFEM). Simulations of Rabi oscillations to control the state of a system inside a quantum box are performed. Our numerical experiments include the transition between two levels of energy and the generation of Schrödinger cat states.",

      "abstract": "The highly structured energy landscape of the loss as a function of parameters for deep neural networks makes it necessary to use sophisticated optimization strategies in order to discover (local) minima that guarantee reasonable performance. Overcoming less suitable local minima is an important prerequisite and often momentum methods are employed to achieve this. As in other non local optimization procedures, this however creates the necessity to balance between exploration and exploitation. In this work, we suggest an event based control mechanism for switching from exploration to exploitation based on reaching a predefined reduction of the loss function. As we give the momentum method a port Hamiltonian interpretation, we apply the ’heavy ball with friction’ interpretation and trigger breaking (or friction) when achieving certain goals. We benchmark our method against standard stochastic gradient descent and provide experimental evidence for improved performance of deep neural networks when our strategy is applied.",

      "abstract": "The port-Hamiltonian (pH) modelling framework allows for models that preserve essential physical properties such as energy conservation or dissipative inequalities. If all subsystems are modelled as pH systems and the inputs are related to the output in a linear manner, the overall system can be modelled as a pH system, too, which preserves the properties of the underlying subsystems. If the coupling is given by a skew-symmetric matrix, as usual in many applications, the overall system can be easily derived from the subsystems without the need of introducing dummy variables and therefore artificially increasing the complexity of the system. Hence the framework of pH systems is especially suitable for modelling multiphysical systems. In this paper, we show that pH systems are a natural generalization of Hamiltonian systems, define coupled pH systems as ordinary and differential-algebraic equations. To highlight the suitability for electrical engineering applications, we derive pH models for MNA network equations, electromagnetic devices and coupled systems thereof.",

However, for differential-algebraic equations (DAEs) it is subjected to many restrictions due to the presence of (possibly hidden) constraints. In order to get convergence of the operator splitting for DAEs, it is important to have and exploit a suitable decoupled structure for the desired DAE system. Here we present a coupled field-circuit modeling via a loop-cutset analysis and the choice of a suitable tree that results in a port-Hamiltonian DAE system. Finally, we introduce an operator splitting approach of such linear coupled field-circuit DAEs and present convergence results for the proposed approach.",

The gradient is computed with the help of sensitivities and the algorithm is tailored such that the structure of the system matrices of the port-Hamiltonian system (skew-symmetry and positive semi-definitness) is preserved in each iteration of the algorithm. As we only require input-output data, we need to calibrate the initial condition of the internal state of the port-Hamiltonian system as well.

Originally, they are Electric Circuit Element BC, here generalized for multidisciplinary fields such as elastic solids, acoustic and thermal devices Their internal field is discretized by the Finite Element Method, thus obtaining the stiffness, damping and mass matrices of a second order ODEs system, transformed then into a first order pH canonical form, having as interaction variables the flow and effort of each terminal.",

Being pH assures energy stability—the total energy of the system cannot increase. It also provides compositionality—larger pH models can be assembled from smaller ones in a standard way that facilitates building pH models in software. Structurally amenable and index $$\\le 1$$ ≤ 1 eliminate the phases of DAE index analysis and reduction, which are commonly used in circuit simulation software. Thus, standard numerical solvers can be applied directly to integrate the DAE. In addition, it has a known a priori block-triangular form that can be exploited for efficient numerical solution. A prototype Matlab code shows high potential for development of this “compact port-Hamiltonian” (CpH) methodology.",

If each DG has passivity property, one can apply this control for all DGs. The model of the considered system is presented using a well-known port-Hamiltonian matrix. Thereby, with an interconnection and damping assignment—passivity-based control (IDA-PBC), global stability is guaranteed. Moreover, applying droop voltage control to change the state-variable references allows for the current sharing between the two DG. To validate the proposed method, simulation results are provided.",

      "abstract": "The main goal of these lecture notes is to survey a series of recent works (Gillis and Sharma, Automatica 85:113–121, 2017; SIAM J. Numer. Anal. 56(2):1022–1047, 2018; Linear Algebra Appl. 623:258–281, 2021; Gillis et al., Numerical Linear Algebra Appl. 25(5):e2153, 2018; Linear Algebra Appl. 573:37–53, 2019; Appl. Numer. Math. 148:131–139, 2020; Choudhary et al., Numerical Linear Algebra Appl. 27(3):e2282, 2020) that aim at solving several nearness problems for a given system. As we will see, these problems can be written as distance problems of matrices or matrix pencils. To solve them, this series of recent works rely on a two-step approach. The first step parametrizes the system using a Port-Hamiltonian representation where stability is guaranteed via convex constraints on the parameters. The second step uses standard non-linear optimization algorithms to optimize these parameters, minimizing the distance between the given system and the sought parametrized stable system. In these lecture notes, we will illustrate this strategy in order to find the nearest stable continuous-time and discrete-time systems, the nearest stable matrix pair, and the nearest positive-real system, as well as generalizations when the eigenvalues need to belong to some set Omega (which is referred to as Omega stability).",

      "abstract": "Operator splitting methods allow to split the operator describing a complex dynamical system into a sequence of simpler sub-systems and treat each part independently. In the modeling of dynamical problems, systems of (possibly coupled) differential-algebraic equations (DAEs) arise. This motivates the application of operator splittings which are aware of the various structural forms of DAEs. Here, we present an approach for the splitting of coupled index-1 DAE as well as for the splitting of port-Hamiltonian DAEs, taking advantage of the energy-conservative and energy-dissipative parts. We provide numerical examples illustrating our second-order convergence results.",

In this paper, we apply an operator splitting that treats the energy-conservative and energy-dissipative parts separately. This paves the way for linear equation solvers to exploit the respective special structures of the iteration matrices as well as the multirate potential in the different right-hand sides. We illustrate the approach using test examples from coupled multibody system dynamics.",

Such systems occur, for instance, in the context of structure-preserving nonlinear model order reduction for port-Hamiltonian systems and, in this context, structure-preserving time discretization is crucial for preserving some of the properties of the time-continuous reduced-order model. For this purpose, we introduce a new class of time discretization schemes which is based on so-called discrete gradient pairs and leads to an exact power balance on the time-discrete level. Moreover, for the special case of a pointwise symmetric and positive definite mass matrix, we present an explicit construction of a discrete gradient pair. Finally, we illustrate the theoretical findings by means of a numerical example, where the time-continuous system is a nonlinear reduced-order model for an advection–diffusion problem.",

      "abstract": "In this chapter we model the traffic dynamics in a wireless communication system (characterized by a set of routers exchanging data with each other) in the port-Hamiltonian framework. Communication systems are characterized by elements which produce significant time delays (by design) in their response, unlike (say) an idealized circuit or mechanical element. Furthermore, the communication between two routers (compositionality) involves losses due to the characteristics of radio signal propagation. In this paper we study the type of Dirac structure used to model a communication element (a router), we analyze the stability properties of a router and finally we study the compositionality properties that evolve under lossy interconnections.",

Starting with an infinite-dimensional port-Hamiltonian system we derive a BM equivalent which can be defined with respect to a non-canonical Dirac structure. Based on this model we derive stability and new passivity properties for the system. The state variables in this case are the “effort” variables and the storage function is a “power-like” function called the mixed potential. The new property is derived by “differentiating” one of the port variables. We present our results with the Maxwell’s equations, and the transmission line with non-zero boundary conditions as examples.",

This work explores the possibility of extending this technique to the case where the plant contains an infinite-dimensional subsystem. Conditions for the existence of Casimir functions reveal the constraints for the application of the design procedure. A simple example of an RLC circuit coupled with an infinite-dimensional transmission line illustrates the main ideas of this paper.",

      "abstract": "The aim of this work is to show how the Dirac structure properties can be exploited in the development of energy-based boundary control laws for distributed port-Hamiltonian systems. Stabilisation of non-zero equilibria has been achieved by looking at, or generating, a set of structural invariants, namely Casimir functions, in closed-loop, and geometric conditions for the problem to be solved are determined. However, it is well known that this method fails when an infinite amount of energy is required at the equilibrium (dissipation obstacle). So, a novel approach that enlarges the class of stabilising controllers within the control by interconnection paradigm is also discussed. In this respect, it is shown how to determine a different control port that is instrumental for removing the intrinsic constraints imposed by the dissipative structure of the system. The general theory is illustrated with the help of two related examples, namely the boundary stabilisation of the shallow water equation with and without distributed dissipation.",

First, to propose a unified, physically motivated, modeling framework—based on port-Hamiltonian systems representations—of the various network topologies used in this application. Second, to prove that the system can be globally asymptotically stabilized with a decentralized PI control that exploits its passivity properties. Close connections between the proposed PI and the popular Akagi’s PQ instantaneous power method are also established. Third, to reveal the transient performance limitations of the proposed controller that, interestingly, is shown to be intrinsic to PI passivity-based control. The performances of the controller are verified via simulations on a three-terminal benchmark example.",

The approach taken uses the formalism of port Hamiltonian systems to track energy exchanged between the mechanical system and virtual potentials or Hamiltonians associated with each image feature. Asymptotic stability of the system is guaranteed by injecting damping to the otherwise conservative system. A simple approach based on full state measurement is presented and then extended to deal with unmeasured relative depth of image features.",

      "abstract": "In this chapter, position control strategies via force feedback are presented for standard mechanical systems in the port-Hamiltonian framework. The presented control strategies require a set of coordinate transformations, since force feedback in the port-Hamiltonian framework is not straightforward. With the coordinate transformations force feedback can be realized while preserving the port-Hamiltonian structure. The port-Hamiltonian formalism offers a modeling framework with a clear physical structure and other properties that can often be exploited for control design purposes, which is why we believe it is important to preserve the structure. The proposed control strategies offer an alternative solution to position control with more tuning freedom and exploit knowledge of the system dynamics.",

The authority is determined on-line according to the trainee’s behavior performance. An evaluation method is introduced based on an adaptive virtual boundary, which results into a time-varing dominance factor. An overruling function is set upstream to solve some specific cases. The system is modeled and controled in port-Hamiltonian form for passivity preserving. Experiments are conducted for validation.",

In contrast, port-Hamiltonian systems, the topic of the current chapter are endowed with the property of (cyclo-)passivity as a consequence of their system formulation. In fact, port-Hamiltonian systems arise from first principles physical modeling. They are defined in terms of a Hamiltonian function together with two geometric structures (corresponding, respectively, to power-conserving interconnection and energy dissipation), which are such that the Hamiltonian function automatically satisfies the dissipation inequality.",

Gas networks can be modeled by partial differential algebraic equations. We identify connected pipe subnetworks that we discretize in space and explore with index and decoupling concepts for differential algebraic equations. For the arising input-output system we derive explicit decoupled representations of the strictly proper part and the polynomial part, only depending on the topology. The proper part is characterized by a port-Hamiltonian form that allows for the development of reduced models that preserve passivity, stability and locally mass. The approach is exemplarily used for an open-loop MOR on a network with a nonlinear active element.",

Elementary components are: (a) an ideal subglottal pressure supply, (b) a glottal flow in a mobile channel, (c) vocal-folds, (d) an acoustic resonator reduced to a single mode. Particular attention is paid to the energetic consistency of each component, to passivity and to the conservative interconnection. Simulations are presented. They show the ability of the model to produce a variety of regimes, including self-sustained oscillations. Typical healthy or pathological configuration laryngeal configurations are explored.",

Besides the pH-framework, an energy-based control scheme making heavy use of structural invariants (casimir functions) is presented on the example of a boundary-controlled Euler–Bernoulli beam.",

When a manipulator interacts with an object a very profound change occurs. In fact, before the contact, the controller has to control only the motion of the robot; after the contact, the manipulator dynamically interacts with the environment and the controller has to manage a new dynamical system made up by the robot coupled with the environment. It has been proven in [328] that even if the controlled robot is stable in case of free motion, its behavior could become unstable when there is a contact with the environment.",

      "authors": [],
      "abstract": "Telemanipulation is one of the first fields of application of robotics (see [326] for an early history) and still one of the most challenging. In teleoperation a human operator has to perform a certain task on a remote environment. The human operator commands a local robotic interface (called master ). The motion of the master is transmitted through a communication channel to a remote robot (called slave ) which should replicate the motion of the master and perform a desired task on the remote environment. It is possible to improve performances providing to the human operator some real-time information about the interaction of the slave with the remote environment. This feedback information can be achieved in several ways (e.g. through visual displays, [146]) but the best way to improve the operator’s ability is to feedback the contact force between the slave and the environment to the master side. When the force at the slave side is reflected back to the human operator, it is said that the telemanipulation is controlled bilaterally, or, more simply, that we have a bilateral telemanipulation system . When teleoperation is performed over a great distance, such as in undersea or in space applications, or over packet switching network, such as the Internet, the communication delay associated to the transmission of information from master side to slave side and vice-versa becomes non negligible and it can therefore destabilize the whole system.",

      "abstract": "Stability is a key issue in the implementation of a bilateral telemanipulation system since both the non-negligible time delay in the communication between master and slave and the interaction with unknown environments can destabilize the whole system. In Chap. 4 it has been shown that passivity theory and port-Hamiltonian systems can be fruitfully used to build an intrinsically passive telemanipulation scheme which, therefore, has a stable behavior both in case of free motion and in case of contact with any passive, possibly unknown, environment. Scattering theory has been used to build a communication channel which is lossless independently of any constant transmission delay and the problem of wave reflection arising when coupling master and slave side through scattering based communication channels has been solved. The scheme has been extended in order to take into account the sampled data nature of controllers in a passive way. Moreover discrete scattering has been defined and packet-switching transmission lines have been considered. A communication strategy that allows to preserve passivity even in case of loss of packets and of variable transmission delay has been proposed. Finally, a passivity preserving algorithm that allows to rebuild lost packets by interpolation has been proposed.",

There exist also several extensions to the distributed parameter case. This contribution presents a class of extended distributed parameter Hamiltonian systems, which preserves some useful properties of the well known class of Port Controlled Hamiltonian systems with Dissipation. In addition, special ports are introduced to take the boundary conditions into account. Finally, an introductory example and the example of a piezoelectric structure, a problem with two physical domains, show, how one can use the presented approach for modeling and design.",

After an introductive section, the adaptive internal model design procedure is presented in order to solve the input disturbance problem. This theoretical machinery is specialized for the energy-based port-Hamiltonian framework in order to prove the global asymptotical stability of the solution. Finally, in order to clearly point out the effectiveness of the presented design procedure a tracking problem is solved for a robotic manipulator affected by torque ripples.",

      "abstract": "In this paper an internal model based approach to implicit Fault Tolerant Control for port-Hamiltonian systems is presented: the main idea is to cast the problem into a regulation problem in presence of input disturbances representing exogenous effects of possible faults; this can be solved following an adaptive internal model based approach. The theoretical machinery exploited is specialized for the energy-based port-Hamiltonian formalism in order to prove the global asymptotical stability of the solution. Finally an application example is presented in order to deeply point out the effectiveness of the design procedure presented: a Fault Tolerant Control problem is solved for a magnetic levitation system affected by periodic voltage disturbances.",

These conjugate variables are used to define the composition of port contact systems in the framework of contact geometry. We then propose a power-conserving interconnection structure, which generalizes the interconnection by Dirac structures in the Hamiltonian formalism. Furthermore, the composed system is again a port contact system, as illustrated on the example of a gas-piston system undergoing some irreversible transformation.",

Even if we restrict our analysis to the linear case, it is often impossible to find a closedform solution for this kind of equations, especially in control applications, where the forcing action on the system generates time-varying boundary conditions. Therefore, numerical solvers play a key role as support tools for the analysis of this kind of systems.",

      "abstract": "A bilateral telemanipulator is a robotic system that allows the interaction with remote environments and it is composed by a controlled local robot (the master) and a controlled remote robot (the slave) interconnected through a communication channel. The motion imposed to the master by the human is transmitted to the slave which moves accordingly; when the slave interacts with a remote environment, the interaction force is fed back to the master side in order to improve the perception of the remote environment felt by the user. Passivity theory is a very suitable tool for the implementation of bilateral telemanipulation schemes over delayed communication channels. In passivity based telemanipulation, both master and slave are controlled by means of passive impedance controllers and master and slave sides are interconnected through a scattering based communication channel [ 1 , 8 ] which allows an exchange of information which is passive independently of any constant communication delay. In this way, the overall telemanipulation system is passive and, consequently, its behavior is stable both in case of free motion and in case of interaction with any passive environment. In [ 12 , 11 ], a generic framework for geometric telemanipulation of port-Hamiltonian systems [ 13 ] has been proposed; master and slave are interconnected through intrinsically passive port-Hamiltonian impedance controllers which allow to shape the energetic behavior of the robots and to achieve desired dynamic properties at master and slave sides. Local and remote sides are interconnected through a scattering based communication channel that allows a lossless exchange of energy.",

      "abstract": "In this chapter, we will show how the representation of a lumped-parameter physical system as a bond graph naturally leads to a dynamical system endowed with a geometric structure , called a port-Hamiltonian system . The dynamics are determined by the storage elements in the bond graph (cf. Sect. 1.6.3), as well as the resistive elements (cf. Sect. 1.6.4), while the geometric structure arises from the generalized junction structure of the bond graph. The formalization of this geometric structure as a Dirac structure is introduced as the key mathematical concept to unify the description of complex interactions in physical systems. It will also allow to extend the definition of a finite-dimensional port-Hamiltonian systems as given in this chapter to the infinite-dimensional case in Chapter 4, thus dealing with distributed-parameter physical systems. We will show how this port-Hamiltonian formulation offers powerful methods for the analysis of complex multi-physics systems, also paving the way for the results on control of port-Hamiltonian systems in Chapter 5 and in Chapter 6. Furthermore, we describe how the port-Hamiltonian structure relates to the classical Hamiltonian structure of physical systems as being prominent in e.g. classical mechanics, as well as to the Brayton-Moser description of RLC-circuits.",

We start with the electromechanical domain in Sect. 3.1, while in Sect. 3.2 it is shown how port-Hamiltonian systems can be fruitfully used for the structured modelling of robotics mechanisms. In Sect. 3.3, it is show how to model simple elastic systems either in the Lagrangian and Hamiltonian framework, while, in Sect. 3.4, an expressions of the models representing momentum, heat and mass transfer as well as chemical reactions within homogeneous fluids in the port-based formalism is proposed. To this end, the entropy balance and the associated source terms are systematically written in accordance with the principle of irreversible thermodynamics. Some insights are also given concerning the constitutive equations and models allowing to calculate transport and thermodynamic properties. As it will be shown, for each physical domain, these port-based models can be translated into bond-graph models, in the case of distributed as well as lumped parameters models.",

In the first part it is shown, for different examples of physical systems defined on one-dimensional spatial domains, how the Dirac structure and the port-Hamiltonian formulation arise from the description of distributed parameter systems as systems of conservation laws. In the second part we consider systems of two conservation laws, describing two physical domains in reversible interaction, and it is shown that they may be formulated as port-Hamiltonian systems defined on a canonical Dirac structure called canonical Stokes-Dirac structure. In the third part, this canonical Stokes-Dirac structure is generalized for the examples of the Timoshenko beam, a nonlinear flexible link, and the ideal compressible fluid in order to encompass geometrically complex configurations and the convection of momentum.",

      "abstract": "We discuss in this chapter a number of approaches to exploit the model structure of port-Hamiltonian systems for control purposes. Actually, the formulation of physical control systems as port-Hamiltonian systems may lead in some cases to a re-thinking of standard control paradigms. Indeed, it opens up the way to formulate control problems in a way that is different and perhaps broader than usual. For example, formulating physical systems as port-Hamiltonian systems naturally leads to the consideration of ‘impedance’ control problems, where the behavior of the system at the interaction port is sought to be shaped by the addition of a controller system, and it suggests energy-transfer strategies, where the energy is sought to be transferred from one part the system to another. Furthermore, it naturally leads to the investigation of a particular type of dynamic controllers, namely those that can be also represented as port-Hamiltonian systems and that are attached to the given plant system in the same way as a physical system is interconnected to another physical system. As an application of this strategy of ‘control by interconnection’ within the port-Hamiltonian setting we consider the problem of (asymptotic) stabilization of a desired equilibrium by shaping the Hamiltonian into a Lyapunov function for this equilibrium. From a mathematical point of view we will show that the mathematical formalism of port-Hamiltonian systems provides various useful techniques, ranging from Casimir functions, Lyapunov function generation, shaping of the Dirac structure by composition, and the possibility to combine finitedimensional and infinite-dimensional systems.",

      "abstract": "Infinite dimensional port Hamiltonian systems have been introduced in Chapter 4 as a novel framework for modeling and control distributed parameter systems. In this chapter, some results regarding control applications are presented. In some sense, it is more correct to speak about preliminary results in control of distributed port Hamiltonian systems, since a general theory, as the one discussed in Chapter 5 for the finite dimensional port Hamiltonian systems, has not been completely developed, yet. We start with a short overview on the stability problem for distributed parameter systems in Sect. 6.2, together with some simple but useful stability theorems. Then, in Sect. 6.3, the control by damping injection is generalized to the infinite dimensional case and an application to the boundary and distributed control of the Timoshenko beam is presented. In Sect. 6.4, a simple generalization of the control by interconnection and energy shaping to the infinite dimensional framework is discussed. In particular, the control scheme is developed in order to cope with a simple mixed finite and infinite dimensional port Hamiltonian system. Then, an application to the dynamical control of a Timoshenko beam is discussed in Sect. 6.5.",

We consider the Virtual Body Artificial Potential approach for stabilizing a group of robots at a desired formation. We show that it is possible to model the controlled group of robots as a port-Hamiltonian system and we exploit the scattering framework to achieve a passive behavior of the controlled system and to stabilize the robots in the desired formation independently of any communication delay.",

The finite dimensional system can then be used for simulation or control design. Furthermore, the spatial discretization scheme can also be used for other infinite dimensional systems, e.g. transmission lines.",

As a result of the interconnections algebraic constraints between the state variables commonly arise. This leads to the description of the system by differential-algebraic equations (DAEs), i.e., a combination of ordinary differential equations with algebraic constraints. The basic point of view put forward in this survey paper is that the differential-algebraic equations that arise are not just arbitrary, but are endowed with a special mathematical structure; in particular with an underlying geometric structure known as a Dirac structure. It will be discussed how this knowledge can be exploited for analysis and control.",

Then the control by interconnection method is applied, by using a finite-dimensional controller system interacting via an energy port at the boundary of the infinite-dimensional system. This will be demonstrated by means of a heavy chain system, modelled as a partial differential equation. Furthermore, we sketch the stability proof in the infinite-dimensional setting. To motivate for the presented ideas we recapitulate the well-known concepts for finite-dimensional systems as well, but mainly as a starting point for the discussion of the infinite setting.",

      "abstract": "It is shown how port-based modeling of lumped-parameter complex physical systems (multi-body systems, electrical circuits, electromechanical systems,..) naturally leads to a geometrically defined class of systems, called port-Hamiltonian systems. These are Hamiltonian systems defined with respect to a power-conserving geometric structure capturing the basic interconnection laws, and a Hamiltonian function given by the total stored energy. The structural properties of port-Hamiltonian systems are discussed, in particular the existence of Casimir functions and its implications for stability and stabilization. Furthermore it is shown how passivity-based control results from interconnecting the plant port-Hamiltonian system with a controller port-Hamiltonian system, leading to a closed-loop port-Hamiltonian system. Finally, extensions to the distributed-parameter case are provided by formulating boundary control systems as infinite-dimensional port-Hamiltonian systems.",

An introductory method for simulation based on the state space model is also shown. The results of the simulation demonstrate the effectiveness of the derived model by showing the differences of the responses for the different cation species.",

      "abstract": "This paper discusses model reduction of electrical circuits based on a port-Hamiltonian representation. It is shown that by the use of the Kalman decomposition an uncontrollable and/or unobservable port-Hamiltonian system is reduced to a controllable/observable system that inherits the port-Hamiltonian structure. Energy and co-energy variable representations for port-Hamiltonian systems are defined and the reduction procedures are used for both representations. These exact reduction procedures motivate two approximate reduction procedures that are structure preserving for general port-Hamiltonian systems, one reduction procedure is called the effort-constraint reduction methods. The other procedure is structure preserving under a given condition. A numerical example illustrating the model reduction of a ladder network as a port-Hamiltonian system is considered.",

Based on radial basis function neural network (RBFNN) and direct model reference adaptive control (MRAC), the grid-side controller is designed to regulate output direct current (DC) bus voltage. The coordination control combined sliding model control (SMC) based on signal and port-controlled Hamiltonian (PCH) control based on energy is used to motor-side and achieves the fast speed tracking control and the real-time energy optimization. The controllers based on regenerative braking ensure that the motor can run in four quadrant, energy is bidirectional flow, and the DC bus voltage is controllable. The simulation results demonstrate the validity of the strategy.",

Different from the traditional decoupling control, which is mainly in frequency domain, the method proposed in this paper is implemented directly in time domain. According to the specific requirements of liquid level system control objectives, partial decoupling control is realized by a simply transform. In order to prove the stability, PCH principle is introduced. The simulation results compared with the traditional PCH method illustrate the good performance of the proposed algorithm.",

To solve this problem, a cooperative control strategy of backstepping adaptive neural network (BS-RBFNN) signal control and port controlled Hamiltonian (PCH) energy control is proposed. BS-RBFNN solves the problem of rapidity when the system is in dynamic state, PCH control solves the problem of accuracy when the system is in steady state. The cooperative function based on the error is designed, and the cooperative control of the robot joint system is realized by using this function. The robot joint position servo system can not only realize the rapid adjustment of the dynamic position, but also realize the high precision tracking control in the steady state. Simulation results show that the system achieves fast dynamic response and accurate steady-state position tracking by using cooperative control method.",

PCH system of PMSM views the plant to control from the perspective of overall energy and the interconnection and damping assignment passivity-based (IDA-PBC) control approach based on PCH is single-loop, which has the advantages of simple controller design and fewer adjusting parameters, but causes the problem of overcurrent. The method proposed in this paper solves this problem by setting the coefficient of damping assignment matrix from reinforcement learning of DDPG. First, we give the Hamiltonian model of PMSM. Next, a current-constrained control approach on the basis of PCH and DDPG for PMSM is proposed. Finally, the validity of the method is verified by the simulations.",

      "abstract": "This paper designed a trajectory tracking controller for an underwater vehicle considering model uncertainties and external force disturbances using the Port-Hamiltonian (PH) control theory. Firstly, the mathematical model of the underwater vehicle is established and expressed under the PH framework. However, the hydrodynamic force coefficients inside the mathematical model are hard to obtain accurately without detailed towing tank experiments. To address this, we will propose a parameter observer to estimate the unknown parameters caused by model uncertainties. Meanwhile, the vehicle inevitably suffers from external unknown force disturbances driven by current and wind. So another observer based on passivity theory is proposed to address the unknown fore disturbance. The control law is derived from reshaping kinetic energy and injecting damping terms via the interconnection and damping assignment passivity-based control method. This proposed controller has a physical interpretation. Moreover, it has been proved that the proposed controller can enable vehicles to track the desired trajectory and minimize the tracking errors exponentially. Numerical simulations and comparisons illustrate the stability and effectiveness of the proposed controller to model uncertainties and unknown external disturbances.",

      "abstract": "Many nonlinear control techniques for STATCOM systems are available nowadays. In this chapter several nonlinear feedback controller design techniques relatively simpler and more robust are to be introduced: input–output feedback linearization (IOL) method, passivity-based control (PBC) method, port-controlled Hamiltonian (PCH) method with dynamics extension method. The IOL method has been applied to STATCOM and it shows uniform transient performance. However, the oscillatory response owing to the lightly damped internal dynamics could negatively affect the life cycle of the system and power quality. A modified IOL control scheme is introduced to improve the damping of internal dynamics of performance while preserving overall system stability. Although the IOL methods improve the performance of type 2 STATCOM systems, these methods are sensitive to parameter uncertainty. Moreover, when the system is working in the inductive operating range, undesired oscillatory transient response appears in the DC voltage due to its lightly damped internal dynamics with the IOL method. The PBC method considers the dynamics characteristics of type 2 STATCOM systems, in particular its passive characteristics. Employing the PBC method improves the robustness of controller implementation and simplifies implementation compared to the IOL method in such a way that it avoids canceling the system nonlinearities exactly. However, since the previous methods are designed based on an approximated model of type 2 STATCOM systems, the closed-loop system has a locally stable equilibrium point. Moreover, the stability region is numerically extensively determined. To overcome the aforementioned problem, PCH with the dynamics extension method is developed for a robust and simple structure of nonlinear controller with the non-approximated model of STATCOM systems in order to improve the performance in time domain and enlarge the stability region.",

      "abstract": "A new smooth switching control strategy is devised to ameliorate the position tracking performance of the robotic arms. Firstly, a signal controller is based up the inverse of the modified backstepping sliding model control is project to improve the dynamic property of the system. An energy controller based on port-controlled Hamiltonian system (PCH) was designed and integrated control was introduced as compensation to improve the steady-state performance of the system. Finally, a smooth switching function based on tracking error is devised to achieve smooth switching between signal control and energy control. The permanent magnet synchronous motor (PMSM) motor model is introduced in the design to make the controller more in line with the actual demand, and it is decomposed into position controller and torque controller, which reduce the difficulty of implementation. In the last part of the paper, a two-degree-of-freedom robot is taken as an example to verify the feasibility and advantages of the algorithm.",

      "abstract": "In practical engineering systems, permanent magnet synchronous motors (PMSMs) face challenges such as constrained electrical performance output, excessive energy losses, and discontinuous current transitions during condition switching when operating under multi-condition. To address the above problems, this paper proposes a smooth-switching control strategy that combines maximum torque per ampere (MTPA) and loss minimizing control (LMC). This strategy combines the respective advantages of the two control algorithms and can satisfy the demands of different working conditions. In addition, the proposed smooth-switching mechanism effectively eliminates the discontinuous current conversion problem during multi-condition switching, while mitigating the instability and vibration of the system. Then, the current controller is constructed by means of the port-Hamiltonian method. Meanwhile, energy shaping, damping injection and interconnection configuration approaches are introduced to achieve good steady-state performance of the system. Finally, the simulation results verify the effectiveness of the designed strategy.",

      "abstract": "Nowadays, with the vigorous development of offshore wind power and desert photovoltaic projects, especially with grid-connected inverters as the key interface for renewable energy grid integration, the traditional control methods based on linear architectures such as proportional-integral (PI) control are no longer suitable for the novel scenarios. This is due to the nonlinear scenarios resulting from changes in grid structure or parameters caused by inverters plug-and-play and random switching conditions. In these situations, there is a risk of wide-band oscillation in the grid-connected current. Therefore, this paper proposes a passivity-based feedback controller designed using the port-controlled Hamiltonian model (PCH) for grid-connected inverters operating in traditional grid-following (GFL) modes. Considering nonlinear control delays, a parameter design scheme optimized for multiple performance indexes is obtained using the D-partition method. This scheme ensures that the grid-connected inverter can resist external disturbances and operate reliably under nonlinear conditions, with strong robustness.",

      "abstract": "Satellite formation flying technology constitutes a significant area of research within space missions, with traditional spacecraft capabilities often being constrained by the limitations of propellant use. Electromagnetic Formation Flying (EMFF), a technique that operates without the need for propellant, has garnered considerable interest due to its potential to overcome these limitations. However, the intrinsic strong nonlinearity and coupling within EMFF systems introduce complexities in achieving high-precision control. This research elaborates on the dynamics of a dual EMFF system within the framework of port-Hamiltonian systems, formulating an elaborate, high-accuracy nonlinear dynamic model. Utilized the principle of timed Interconnection and Damping Assignment, the research proposes a control strategy specifically devised for EMFF, facilitating the regulation of magnetic dipole strengths among the formation satellites. The practicality and efficiency of this approach are subsequently corroborated through numerical simulations, demonstrating its applicability to Projected Circular Orbit formation reconfiguration endeavors.",

      "abstract": "Due to the extensive application of converter parallel system with multiple-energy storage converters in DC systems, it becomes difficult for the converter parallel system to quickly stabilize at the new desired operating point when the system under large disturbance, thus affecting the stability of the energy storage system. To address this issue, the improved passivity-based controller is designed based on the Port-Controlled Hamiltonian with Dissipation (PCHD) model by means of the damping and interconnection injecting. At the same time, the Virtual DC Machine (VDCM) control is adopted to solve the adaptability of improved passivity-based controller, this strategy provides additional inertia and damping to the parallel system of multiple-energy storage converters, while enhancing the dynamic and steady-state characteristics of the system under large disturbances. Finally, simulation and experimental results demonstrate that the proposed control strategy can not only stabilizes the multi-energy storage parallel converter system under large disturbances but also effectively suppresses fluctuations and steady-state errors in the output voltage. Compared to the traditional Interconnection and Damping assignment Passivity-Based Control (IDA-PBC) strategy, it exhibits smaller voltage overshoot, faster adjustment speed, and better dynamic characteristics.",

      "abstract": "Port-Hamiltonian systems (PHS) are increasingly popular modelling approaches for nonlinear physical systems. In this contribution, we identify a general class of microscopic force-based pedestrian models that can be formulated as a port-Hamiltonian system. The port-Hamiltonian paradigm allows for identification of new fundamental physical modelling components of pedestrian dynamics. The skew-symmetric term specific to the conservative Hamiltonian structure of the PHS corresponds to pedestrian isotropic interaction forces. The dissipation to the input port accounts for the pedestrian’s desired velocity and sensitivity, the input acting in the PHS as a feedback control. Some simulations of counter-flow are performed on a torus. Interestingly, a phase transition from disorder dynamics to self-organising lane formation occurs as the conservative forces become weak relative to the dissipation and control forces. A critical parameter setting for lane formation can then be identified using the Hamiltonian as an order parameter.",

Specialized to the case of Lagrangian systems this definition generates the Euler-Lagrange equations with external forces. Further interconnections of Hamiltonian systems are treated and the close relationship with network theory is showed. Finally the newly developed theory is applied to the study of symmetries and to a realization theory for Hamiltonian systems. It will be argued that this way of describing Hamiltonian systems can be extended to a broader class of physical systems.",

The main result is that, through the introduction of a discrete directional derivative, implicit second-order conserving schemes can be constructed for general systems which preserve the Hamiltonian along with a certain class of other first integrals arising from affine symmetries. Discrete Hamiltonian systems are introduced as formal abstractions of conserving schemes and are analyzed within the context of discrete dynamical systems; in particular, various symmetry and stability properties are investigated.",

      "abstract": "Die Mechatronik, einst als wissenschaftliches und industrielles Experiment begonnen, hat sich zu einer etablierten Wissenschaft mit einem weiten industriellen Anwendungsfeld entwickelt. Unverändert geblieben ist der Anspruch, aus der integrativen Verbindung von Elektrotechnik, Maschinenbau und Automatisierungstechnik ein Wissensgebiet zu schaffen, das einen neuen Zugang zu wissenschaftlichen und industriellen Problemen bietet. Am Beispiel zweier Systeme der Stahlindustrie, eines hydraulischen Aktuators und an S-Rollen-Systemen, wird gezeigt, wie mit Hilfe linearer und nichtlinearer Regelungen das Verhalten der Systeme wesentlich verbessert werden kann. Der Entwurf der Regelung basiert im nicht-linearen Fall dabel auf der Theorie der PCHD-Systeme (port controlled Hamiltonian systems with dissipation) und im linearen Fall auf einer partiellen Eingangs-Ausgangs-Entkopplung, kombiniert mit einem H _2-Entwurf. Die Güte der so entworfenen Systeme wird durch Messungen an realen Anlagen und durch Simulationsstudien nachgewiesen. Diese Regelungen sind natürlich auch bei anderen Anlagen einsetzbar. Darüber hinaus sind die vorgestellten Konzepte auch auf ähnliche oder nur verwandte industrielle Probleme leicht übertragbar. Mechatronics, once started as a scientific and industrial experiment, has shown to be a well established scientific discipline with a broad industrial area of applications. Unchanged is the claim of Mechatronics to create a scientific discipline, which offers a new approach to industrial and scientific problems by a synergetic integration of electrical and mechanical engineering with control. Two examples from the field of steel manufacturing systems, namely a hydraulic actuator and a bridle roll device, are chosen in order to demonstrate how one can improve the system performance by linear and nonlinear control. The theory of PCH-systems (port controlled Hamiltonian systems) is used in the nonlinear case, and a combination of partial input-output decoupling and H_2-design is applied to the linear plant. The measurements of the hydraulic actuator and the simulations of the bridle roll system demonstrate the performance of the closed loop. Of course, the presented controllers can easily be used for similar plants. Furthermore, the presented ideas are transferable to similar or related problems in a straightforward manner.",

The structural properties of these systems are investigated, in particular the existence of Casimir functions and their implications for stability. It is shown how the power-conserving interconnection with a controller system which is also a port-controlled Hamiltonian system defines a closed-loop port-controlled Hamiltonian system; and how this may be used for control by shaping the internal energy. Finally, extensions to implicit system descriptions (constraints, no a priori input-output structure) are discussed.",

      "abstract": "In this chapter a general setting for telemanipulation of Port Control Hamiltonian systems has been presented. A new system theoretic condition has been introduced which can be used to test if proper matching is taking place. A possible measure of matching has been also introduced. It has been shown that the standard form of explicit port controlled Hamiltonian systems is not general enough to obtain matching and it must be extended by a feed-throw term. This can be shown more generally using directly a network structure as shown in Sect. 6.4.1. The presented theory is important for the implementation of geometrical telemanipulation where the vector space used se (3) does not have an internal product.",

      "abstract": "The solution of constrained linear partial-differential equations can be described via parametric representations of linear relations. To study these representations, we provide a novel definition of boundary triplets for linear relations in range representations where the associated boundary map is defined on the domain of the parameterizing operators rather than the relation itself. This allows us to characterize all boundary conditions such that the underlying dynamics is represented by a self-adjoint, skew-adjoint or maximally dissipative relation. The theoretical results are applied to a class of implicit port-Hamiltonian systems on one-dimensional spatial domains. More precisely, we explicitly construct a boundary triplet which solely depends on the coefficient matrices of the involved matrix differential operators and we derive the associated Lagrangian subspace. We exemplify our approach by means of the Dzektser equation, the biharmonic wave equation, and an elastic rod with non-local elasticity condition.",

The so-called port-Hamiltonian systems cover, for instance, the wave equation and the transport equation, but also networks of the aforementioned equations fit into this framework. Our main results firstly characterize the boundary conditions which turn the corresponding linear operator into the generator of a strongly continuous semigroup. Secondly, we equip the equation with inputs (control) and outputs (observation) at the boundary and prove that this leads to a well-posed boundary control system. We illustrate our results via an example of coupled transport equations on a network that allows to model transport from and to infinity. Moreover, we study a vibrating string of infinite length with one endpoint. Here, we show that our results allow to treat cases where the physical constants of the string tend to zero at infinity.",

We show that under additional monotonicity conditions on the network’s components, the circuit enjoys the property of relative passivity, an extended notion of classical passivity. The property of relative passivity is then used to build simple, yet robust and globally stable, proportional plus integral controllers.",

      "abstract": "This article proposes an improved nonlinear (IN) robust control strategy for the grid-side voltage-source converter (GSVSC) of a VSC-based high-voltage direct current (VSC-HVDC) transmission system connected to a large wind farm by the using Hamiltonian function method. With the help of variable transformation, the nonlinear model with parameter uncertainties and external disturbances of the GSVSC is changed into the port-controlled dissipative Hamiltonian (PCDH) system. Based on the PCDH system, an IN robust control law is established. In order to demonstrate the effectiveness and robustness of the IN robust control, the backstepping power control (BPC), which is developed by using the backstepping design procedure in the sense of Lyapunov stability theorem for the GSVSC to satisfy the control objectives of a stable HVDC bus and the grid connection with a unity power factor, is selected as a comparison object. Generally speaking, the system used by the backstepping method must have special strict feedback of the lower triangular structure, but the wind farm connected to the power grid with the VSC-HVDC is a multivariable structure and highly coupled nonlinear system. So, the BPC cannot effectively maintain and utilize the nonlinear characteristics of the VSC-HVDC system, while this nonlinear physical structure characteristics is very useful for the design of a nonlinear controller. The greatest advantage of the Hamilton function method is that it can effectively keep and utilize the nonlinear characteristics of the system. The simulation results indicate that the proposed IN control designed by using the Hamilton function method gains the advantage over the BPC under a variety of operating conditions.",

      "abstract": "The operational performances of the conventional permanent magnet synchronous motor drive systems are affected by complex work conditions, sudden load changes, and external disturbances. For the nonlinear control of a permanent magnet synchronous motor, a passive control method based on ADRC and PCHD with disturbance observation is proposed. The disturbance of the current loop is estimated and compensated by the disturbance observer, and the feedback control law is obtained by interconnection and damping configuration, thus the port-controlled Hamiltonian with dissipation based on perturbation observation is designed. With the introduction of active disturbance rejection control, the system has stronger robustness to external disturbance. The experimental results show that compared with the PI control and ADRC method, the proposed method reduces overshoot effectively and improves the response speed of the system. The control system has the better performance of anti-disturbance.",

Using the technique of modulated Fourier expansions with state-dependent frequencies, which is newly developed here, the following results are proved: the considered Hamiltonian systems have the action as an adiabatic invariant over long times that cover arbitrary negative powers of the small parameter. The Störmer–Verlet method approximately conserves a modified action and a modified total energy over a long time interval that covers a negative integer power of the small parameter. This power depends on the size of the product of the stepsize with the high frequency.",

The approach is based on rewriting the problem in a canonical form that complies with the underlying energy-dissipation structure. We show that the corresponding weak formulation then allows for a dissipation-preserving approximation by Galerkin methods in space and discontinuous Galerkin methods in time. The proposed methodology is rather general and can be applied to a wide range of applications. This is demonstrated by discussion of some typical examples ranging from diffusive partial differential equations to dissipative Hamiltonian systems.",

The governing equations can be formulated as an abstract dissipative Hamiltonian system which allows us to derive perturbation bounds via relative energy estimates using a problem adapted nonlinear analysis. As particular consequences of these results, we are able to prove stability estimates with respect to initial conditions and model parameters and we conduct a quantitative asymptotic analysis in the high friction limit. Our results are established first for the flow in a single pipe and we then extend our analysis to pipe networks in the spirit of energy-based port-Hamiltonian modelling.",

The dynamic iteration is monotone in the sense that the error is decreasing and no stability conditions are required. The developed iteration scheme is even new for linear port-Hamiltonian systems governed by ODEs. The obtained algorithm is applied to a multibody system and an electrical network.",

Additionally, we apply the proposed discretization techniques to obtain numerical integrators for port-Hamiltonian systems and we discuss how to merge the discretization procedure and the constraint algorithm associated to systems of implicit differential equations. After fixing a time step, discretization maps are used to discretize the configuration manifold and we obtain different geometric integrators for the given implicit differential equations. As a result we propose a new method that exactly preserves the integrable part of those equations.",

      "abstract": "This paper considers numerical approximations of a Timoshenko beam under boundary control. The continuous system under boundary feedback is known to be exponentially stable. Firstly, the continuous system is transformed into an equivalent first-order port-Hamiltonian formulation. A basically order reduction finite difference scheme is applied to derive a family of semi-discretized systems. Secondly, a completely new method which is based on a mixed discrete observability inequality involving final state observability and exact observability is developed to prove the uniform exponential stability of the discrete systems. More interestingly, the proof for the stability of discrete systems is almost parallel to that of the continuous counterpart. Thirdly, the solutions of the semi-discretized systems are shown to be strongly convergent to the solution of the original system through Trotter-Kato theorem. Finally, both exact controllability of continuous system and the discrete systems are proved in light of Russell’s “controllability via stability” principle and the explicit controls are derived. Moreover, the discrete controls are shown in first time to be convergent to the continuous control by proposed approach.",

      "abstract": "Motion planning and stabilization of the inverted pendulum on a cart is a much-studied problem in the control community. We focus our attention on asymptotically stabilizing a vertically upright flexible beam fixed on a moving cart. The flexibility of the beam is restricted only to the direction along the traverse of the cart. The control objective is to attenuate the effect of disturbances on the vertically upright profile of the beam. The control action available is the motion of the cart. By regulating this motion, we seek to regulate the shape of the beam. The problem presents a combination of a system described by a partial differential equation (PDE) and a cart modeled as an ordinary differential equation (ODE) as well as a controller which we restrict to an ODE. We set our problem in the port-controlled Hamiltonian framework. The interconnection of the flexible beam to the cart is viewed as a power-conserving interconnection of an infinite-dimensional system to a finite-dimensional system. The energy-Casimir method is employed to obtain the controller. In this method, we look for some constants of motion that are invariant of the choice of controller Hamiltonian. These Casimirs relate the controller states to the states of the system. We finally prove the stability of the equilibrium configuration of the closed-loop system.",

In particular, suitably choosing the space of flow and effort variables we will show how several elements coming from possibly different physical domains can be interconnected in order to describe a dynamic system perturbed by general continuous semimartingale. Relevant enough, the noise does not enter into the system solely as an external random perturbation, since each port is itself intrinsically stochastic. Coherently to the classical deterministic setting, we will show how such an approach extends existing literature of stochastic Hamiltonian systems on pseudo-Poisson and pre-symplectic manifolds. Moreover, we will prove that a power-preserving interconnection of stochastic port-Hamiltonian systems is a stochastic port-Hamiltonian system as well.",

      "abstract": "In this paper, we present a novel approach to the geometric formulation of solid and fluid mechanics within the port-Hamiltonian framework, which extends the standard Hamiltonian formulation to non-conservative and open dynamical systems. Leveraging Dirac structures, instead of symplectic or Poisson structures, this formalism allows the incorporation of energy exchange within the spatial domain or through its boundary, which allows for a more comprehensive description of continuum mechanics. Building upon our recent work in describing nonlinear elasticity using exterior calculus and bundle-valued differential forms, this paper focuses on the systematic derivation of port-Hamiltonian models for solid and fluid mechanics in the material, spatial, and convective representations using Hamiltonian reduction theory. This paper also discusses constitutive relations for stress within this framework including hyper-elasticity, for both finite and infinitesimal strains, as well as viscous fluid flow governed by the Navier–Stokes equations.",

      "abstract": "We develop inductive biases for the machine learning of complex physical systems based on the port-Hamiltonian formalism. To satisfy by construction the principles of thermodynamics in the learned physics (conservation of energy, non-negative entropy production), we modify accordingly the port-Hamiltonian formalism so as to achieve a port-metriplectic one. We show that the constructed networks are able to learn the physics of complex systems by parts, thus alleviating the burden associated to the experimental characterization and posterior learning process of this kind of systems. Predictions can be done, however, at the scale of the complete system. Examples are shown on the performance of the proposed technique.",

      "abstract": "The modeling framework of port-Hamiltonian systems is systematically extended to linear constrained dynamical systems (descriptor systems, differential-algebraic equations) of arbitrary index and with time-varying constraints. A new algebraically and geometrically defined system structure is derived. It is shown that this structure is invariant under equivalence transformations, and that it is adequate also for the modeling of high-index descriptor systems. The regularization procedure for descriptor systems to make them suitable for simulation and control is modified to preserve the port-Hamiltonian form. The relevance of the new structure is demonstrated with several examples.",

Using global geometric and algebraic points of view, translations between different representations are presented. Characterizations are also derived when a general DAE system can be transformed into one of these structured representations. Approaches for computing the structural information and the described transformations are derived that can be directly implemented as numerical methods. The results are demonstrated with a large number of examples.",

      "abstract": "The relation between passive and positive real systems has been extensively studied in the literature. In this paper, we study their connection to the more recently used notion of port-Hamiltonian descriptor systems. It is well-known that port-Hamiltonian systems are passive and that passive systems are positive real. Hence it is studied under which assumptions the converse implications hold. Furthermore, the relationship between passivity and KYP inequalities is investigated.",

This manuscript presents a discrete-time pH descriptor formulation for linear, completely causal, scattering passive dynamical systems based on the system coefficients. The relation of this formulation to positive and bounded real systems and the characterization via positive semidefinite solutions of Kalman–Yakubovich–Popov inequalities is also studied.",

Then, under controllability assumptions, it is shown that the optimal control problem exhibits a manifold turnpike property.",

(Port-Hamiltonian descriptor systems are generically controllable and stabilizable. Submitted to Mathematics of Control, Signals and Systems, 2023. https://arxiv.org/abs/2302.05156 ) on (relative) generic controllability of port-Hamiltonian descriptor systems. We extend their results to (relative) genericity of observability. For unstructured differential-algebraic systems, criteria for (relative) generic observability are derived from Ilchmann and Kirchhoff (Math Control Signals Syst 35:45–76, 2023. https://doi.org/10.1007/s00498-021-00287-x ) using duality. This is not possible for port-Hamiltonian systems. Hence, we tweak the results of Ilchmann et al. (Port-Hamiltonian descriptor systems are generically controllable and stabilizable. Submitted to Mathematics of Control, Signals and Systems, 2023. https://arxiv.org/abs/2302.05156 ) and derive similar criteria as for the unstructured case. Additionally, we consider certain rank constraints on the system matrices.",

Aiming for a direct structure-preserving approach, we employ techniques from optimal control with ordinary differential equations and define a constrained optimization problem. The input-to-state stability is discussed which is the key step towards the existence of optimal controls. Further, we derive the first-order optimality system taking into account the port-Hamiltonian structure. Indeed, the proposed method preserves the skew symmetry and positive (semi)-definiteness of the system matrices throughout the optimization iterations. Numerical results with perturbed and unperturbed synthetic data, as well as an example from the PHS benchmark collection [ 17 ] demonstrate the feasibility of the approach.",

We extend the result from general, unstructured differential-algebraic equations to differential-algebraic equations of port-Hamiltonian type. We derive results on relative genericity. These findings are the basis for characterizing relative generic controllability of port-Hamiltonian systems in terms of dimensions. A similar result is proved for relative generic stabilizability.",

      "abstract": "This paper is dedicated to structure-preserving spatial discretization of shallow water dynamics. First, a port-Hamiltonian formulation is provided for the two-dimensional rotational shallow water equations with viscous damping. Both tangential and normal boundary port variables are introduced. Then, the corresponding weak form is derived and a partitioned finite element method is applied to obtain a finite-dimensional continuous-time port-Hamiltonian approximation. Four simulation scenarios are investigated to illustrate the approach and show its effectiveness.",

      "abstract": "We introduce an energy-based model, which seems especially suited for constrained systems. The proposed model generalizes classical port-Hamiltonian input–state–output systems and exhibits similar properties such as energy dissipation as well as structure-preserving interconnection and Petrov–Galerkin projection. In terms of time discretization, the midpoint rule and discrete gradient methods are dissipation-preserving. Besides the verification of these properties, we present ten examples from different fields of application illustrating the great flexibility of the proposed framework.",

In particular, we use the theory of system nodes as reported by Staffans (Well-posed linear systems. Encyclopedia of mathematics and its applications, Cambridge University Press, Cambridge, UK, 2005) to formulate a suitable concept for port-Hamiltonian systems, which allows a unifying approach to systems with boundary as well as distributed control and observation. The concept presented in this article is further neither limited to parabolic nor hyperbolic systems, and it also covers partial differential equations on multi-dimensional spatial domains. Our presented theory is substantiated by means of several physical examples.",

      "abstract": "The relationship between different dissipativity concepts for linear time-varying systems is studied, in particular between port-Hamiltonian systems, passive systems, and systems with nonnegative supply. It is shown that linear time-varying port-Hamiltonian systems are passive, have nonnegative supply rates, and solve (under different smoothness assumptions) Kalman–Yakubovich–Popov differential and integral inequalities. The converse relations are also studied in detail. In particular, sufficient conditions are presented to obtain a port-Hamiltonian representation starting from any of the other dissipativity concepts. Two applications are presented.",

The approach extends previous port-Hamiltonian characterizations to include the general non-minimal case and the case where the feedthrough term fails to have an invertible symmetric part. The resulting construction is able to identify infeasibility when the system fails to be port-Hamiltonian, and allows for the incorporation of perturbations in order to arrive at a nearby port-Hamiltonian system. Results are illustrated via numerical examples.",

As the dissipation inequality plays a crucial role for deterministic PHS, we develop several passivity concepts for stochastic input-state-output systems and characterize these in terms of the parameters of the system. Afterward, we examine properties of a certain class of linear stochastic systems that can be regarded as an extension of linear deterministic PHS to a stochastic passivity framework.",

      "abstract": "This work proposes a novel structure-preserving model reduction ( MOR ) method for linear, time-invariant port-Hamiltonian ( pH ) systems. Our goal is to construct a reduced-order pH system, which can still be interpreted in the physical domain of the full order model. By this we mean, that if an electrical circuit is the initial high-dimensional pH system, we want the reduced-order model to be still interpretable as an electronic circuit. In the case of the well-known mass spring damper ( MSD ) system, there are MOR methods available, which already guarantee the preservation of this particular structure. Moreover, we show that our new structure-preserving MOR method, which is based on symplectic MOR methods, will recover the known second-order Arnoldi method in the case of MSD systems. However, for the example of an electrical circuit pH model (and more models of similar block structure), our method yields a novel model reduction method. We present numerical results on the aforementioned electronic circuit model, highlighting the advantages of the proposed method.",

      "abstract": "Trajectory tracking with disturbance rejection is a challenging problem in robotics, particularly in applications involving selective compliance articulated robot arms (SCARA). In this paper, we address the trajectory tracking problem with the presence of disturbances in applying SCARA, by designing controllers with active force control (AFC)-based control methods. AFC has shown potential in disturbance rejection, and its per efficiency of the designed controllers, we integrated different machine learning techniques into the AFC controller, including iterative learning (IL), adaptive neuro-fuzzy inference system (ANFIS) and reinforcement learning (RL). Two case studies were conducted and compared with two different benchmark controllers to validate intelligent AFC-based controllers: a port-controlled Hamiltonian (PCH) control and a hybrid proportional-integral-derivative (PID) control. The results demonstrate that the AFC-based controllers consistently outperform the benchmark methods. Specifically, in Case 1, the AFC-RL controller achieves a 99.99% improvement in root mean square error for joint 1 compared to the hybrid PID control. In Case 2, the AFC-RL controller outperforms the AFC-IL controller in trajectory tracking accuracy by 98.71%. Also, disturbance rejection ability was tested on the AFC-based controllers with various types of disturbances. Among the three AFC-based controllers, AFC-RL shows the best performance. The findings highlight the potential of integrating machine learning into AFC for more accurate and efficient robotic control.",

      "abstract": "This paper deals with generalization of the Brayton–Moser network decomposition and related structural properties to a relatively large class of finite dimensional strictly causal systems, which can be described in the state-space representation form. The resulting energy-metric function is defined for dissipative systems and is induced by the output signal dissipation power. It is demonstrated that such a power-oriented approach determines both, the structure of a system representation as well as the corresponding system state space topology. A special form of physically correct internal structure of an equivalent state space representation has been derived as a natural consequence of strict causality, the state-space energy conservation, dissipativity assumption and the state minimality requirement.",

Motivated by the physical interpretation offered by the port-controlled Hamiltonian system class in the finite-dimensional case, we analyse an extension of this framework to the infinite-dimensional scenario on the basis of the so-called evolutionary approach which is used for the port-Hamiltonian formulation of flexible beams modelled according to the Timoshenko theory. Furthermore, we adapt the well-known control via structural invariants method with respect to the presented port-Hamiltonian description such that this method is applied to the boundary control of the Timoshenko beam.",

      "abstract": "Das Fahrwerk von Straßenfahrzeugen steht seit jeher für Fahrdynamik, Fahrsicherheit und Fahrkomfort. Der bewussten Einflussnahme auf diese Größen zur Auflösung von Designzwängen und Zielkonflikten wird sich bereits seit mehreren Jahrzehnten intensiv gewidmet. So zielt auch der vorliegende Beitrag auf Verbesserung des Fahrkomforts ab. Dies soll durch Isolation der Fahrzeugaufbaudynamik vom Rad mittels eines semiaktiven Fahrwerks erfolgen. Die Bewegungen des Rades sollen nicht mehr (vollständig) auf den Fahrzeugaufbau übertragen und somit dessen Schwingungsanregung reduziert werden. Regelungstechnisch umgesetzt wird dieser Ansatz anhand der passivitätsbasierten Regelungsmethode „Interconnection and Damping Assignment“ (IDA). Um die Freiheitsgrade bei der Reglersynthese bewusst einzuschränken, wurde eine systematische und physikalisch nachvollziehbare Vorgehensweise basierend auf der Analyse der stabilitätsrelevanten Teilsystemstruktur gewählt. Im Beitrag enthalten, ist eine kurze Einführung in die Systemtheorie zur Passivität, in „Port Controlled Hamiltonian Systems with Dissipation“ (PCHD-Systeme) sowie in die IDA Reglersynthese. Die Modellbildung basiert auf einen Viertelfahrzeugversuchsstand des Instituts für Steuer- und Regelungstechnik der Universität der Bundeswehr München. Anhand dieses Versuchsstands wurde eine Reglerparametrierung auf Basis von Simulationen und praktischer Erprobung durchgeführt. Abschließend erfolgt eine Betrachtung von Stabilität und Passivität zum geschlossenen System. The chassis suspension of road vehicles has always stood for driving dynamics, driving safety and driving comfort. The deliberate influence on these variables for the dissolution of design constraints and conflicting objectives has been the subject of intensive attention for several decades. Thus, the present article aims at improving the driving comfort. This is done by isolating the vehicle body dynamics from the wheel by means of a semi-active suspension. The movements of the wheel are no longer (completely) transmitted to the vehicle body and thus its vibration excitation can be reduced. In order to implement this approach, the passive-based control method “Interconnection and Damping Assignment” (IDA) was used to limit the degrees of freedom in controller synthesis, and a systematic and physically comprehensible approach was chosen based on the analysis of the stability-relevant subsystem structure. Included in this article is a brief introduction to systems theory of passivity, “Port Controlled Hamiltonian Systems with Dissipation” (PCHD), and IDA controller synthesis. The modelling is based on a quarter-vehicle test stand of the Institute of Control Engineering of the University of the Federal Armed Forces in Munich. On basis of this test stand, a controller parameterization based on simulations and practical testing was carried out. Finally, a consideration of stability and passivity to the closed system has been done.",

      "abstract": "After recalling the definitions of standard port-Hamiltonian systems and their algebraic constraints, called here Dirac algebraic constraints, an extended class of port-Hamiltonian systems is introduced. This is based on replacing the Hamiltonian function by a general Lagrangian submanifold of the cotangent bundle of the state space manifold, motivated by developments in (Barbero-Linan et al., J. Geom. Mech. 11, 487–510, 2019 ) and extending the linear theory as developed in (van der Schaft and Maschke, Syst. Control Lett. 121, 31–37, 2018 ) and (Beattie et al., Math. Control Signals Syst. 30, 17, 2018 ). The resulting new type of algebraic constraints equations are called Lagrange algebraic constraints. It is shown how Dirac algebraic constraints can be converted into Lagrange algebraic constraints by the introduction of extra state variables, and, conversely, how Lagrange algebraic constraints can be converted into Dirac algebraic constraints by the use of Morse families.",

      "abstract": "This paper proposes a novel control method for path-following of joints of a snake robot. The proposed method applies the port-controlled Hamiltonian based approach, which has originally been proposed for a full-actuated friction-less system. This paper extends the controller for an under-actuated system with friction. It is proven that, by the proposed controller, the path-following of the joints is achieved. The validity of the controller is checked through simulations. Furthermore, simulation results suggest that the controller is robust to modeling errors.",

      "abstract": "Cyber–physical systems (CPS) such as automotive control systems consist of various interacting cyber and physical components. Heterogeneous domains, composition of multiple components, complex dynamics, and nonlinearities result in significant challenges for design, modeling, and simulation of CPS. Model-based design can be used to address such challenges, but it is very important to use physically accurate heterogeneous models that can be composed to represent the overall system behavior. Further, it is important to preserve the properties derived from analyses based on the mathematical models in the control system implementation in order to reduce costly testing and design changes late in the development cycle. This paper proposes a model-based design methodology for automotive control software using port-Hamiltonian systems (PHS). PHS are used to model the vehicle dynamics, speed and steering control systems, and the interactions between physical and cyber components. Passivity analysis is used to design the controllers and ensure system stability. More importantly, the proposed approach guarantees that passivity is preserved after time-discretization and quantization of the controllers. The models are then used for code generation and compilation, scheduling, and software deployment, ensuring that passivity is preserved by the control system implementation. We evaluate the methodology using an automotive control design case study implemented on a hardware-in-the-loop simulation platform and present simulation results to demonstrate its effectiveness.",

      "abstract": "Projection-based model order reduction of dynamical systems usually introduces an error between the high-fidelity model and its counterpart of lower dimension. This unknown error can be bounded by residual-based methods, which are typically known to be highly pessimistic in the sense of largely overestimating the true error. This work applies two improved error bounding techniques, namely (a)  a hierarchical error bound and (b)  an error bound based on an auxiliary linear problem , to the case of port-Hamiltonian systems. The approaches rely on a secondary approximation of (a) the dynamical system and (b) the error system. In this paper, these methods are adapted to port-Hamiltonian systems. The mathematical relationship between the two methods is discussed both theoretically and numerically. The effectiveness of the described methods is demonstrated using a challenging three-dimensional port-Hamiltonian model of a classical guitar with fluid–structure interaction.",

A passive paradigm is introduced for shared virtual object (SVO) with n distributed copies on communications with unreliable data transmission. The n -port passivity of the SVO system is proved and followed by the steady-state analysis. Three-user haptic cooperation experiments validate the theoretical findings.",

      "abstract": "We study linear dissipative Hamiltonian (DH) systems with real constant coefficients that arise in energy based modeling of dynamical systems. We analyze when such a system is on the boundary of the region of asymptotic stability, i.e., when it has purely imaginary eigenvalues, or how much the dissipation term has to be perturbed to be on this boundary. For unstructured systems the explicit construction of the real distance to instability ( real stability radius ) has been a challenging problem. We analyze this real distance under different structured perturbations to the dissipation term that preserve the DH structure and we derive explicit formulas for this distance in terms of low rank perturbations. We also show (via numerical examples) that under real structured perturbations to the dissipation the asymptotical stability of a DH system is much more robust than for unstructured perturbations.",

      "abstract": "For several classes of mathematical models that yield linear systems, the splitting of the matrix into its Hermitian and skew Hermitian parts is naturally related to properties of the underlying model. This is particularly so for discretizations of dissipative Hamiltonian ODEs, DAEs and port-Hamiltonian systems where, in addition, the Hermitian part is positive definite or semi-definite. It is then possible to develop short recurrence optimal Krylov subspace methods in which the Hermitian part is used as a preconditioner. In this paper, we develop new, right preconditioned variants of this approach which, as their crucial new feature, allow the systems with the Hermitian part to be solved only approximately in each iteration while keeping the short recurrences. This new class of methods is particularly efficient as it allows, for example, to use few steps of a multigrid solver or a (preconditioned) CG method for the Hermitian part in each iteration. We illustrate this with several numerical experiments for large scale systems.",

      "abstract": "Aiming at the unsatisfactory performance of Two Degree-of-Freedom joint robot trajectory tracking control system which is controlled by one method, a hybrid control method that integrates Port-Controlled Hamiltonian and Proportional Differential algorithm is designed. The Port-Controlled Hamiltonian control is used to ensure the stability of the system, and Proportional Differential control is used to improve the response speed of the system. Exponential function is used as the hybrid function to achieve the coordinated control strategy, and to adapt to the error disturbance of Two Degree-of-Freedom joint robot. The control system not only realizes the fast-tracking control, but also raises the output signal of the robot to a higher precision. The simulation results show that when the modelling error exists in the mechanical system of Two Degree-of-Freedom joint robot, the hybrid control trajectory tracking system takes on both advantages of the two methods. It has good dynamic performance and steady-state performance. In addition, it can eliminate the error quickly.",

      "abstract": "A continuous Galerkin finite element method that allows mixed boundary conditions without the need for Lagrange multipliers or user-defined parameters is developed. A mixed coupling of Lagrange and Raviart-Thomas basis functions are used. The method is proven to have a Hamiltonian-conserving spatial discretisation and a symplectic time discretisation. The energy residual is therefore guaranteed to be bounded for general problems and exactly conserved for linear problems. The linear 2D wave equation is discretised and modelled by making use of a port-Hamiltonian framework. This model is verified against an analytic solution and shown to have standard order of convergence for the temporal and spatial discretisation. The error growth over time is shown to grow linearly for this symplectic method, which agrees with theoretical results. A modal analysis is performed which verifies that the eigenvalues of the model accurately converge to the exact eigenvalues, as the mesh is refined. The port-Hamiltonian framework allows boundary coupling with bond-graph or, more generally, lumped parameter models, therefore unifying the two fields of lumped parameter modelling and continuum modelling of Hamiltonian systems. The wave domain discretisation is shown to be equivalent to a coupling of canonical port-Hamiltonian forms. This feature allows the model to have mixed boundary conditions as well as to have mixed causality interconnections with other port-Hamiltonian models. A model of the 2D wave equation is coupled, in a monolithic manner, with a lumped parameter model of an electromechanical linear actuator. The combined model is also verified to conserve energy exactly.",

      "abstract": "We describe a symplectic approach towards thermodynamics in which thermodynamic transformations are described by (symplectic) Hamiltonian dynamics. Upon identifying the spaces of equilibrium states with Lagrangian submanifolds of a symplectic manifold, we present a Hamiltonian description of thermodynamic processes where the space of equilibrium states of a system in a certain ensemble is contained in the level set on which the Hamiltonian assumes a constant value. In particular, we work out two explicit examples involving the ideal gas and then describe a Hamiltonian approach towards constructing maps between related thermodynamic systems, e.g., the ideal (non-interacting) gas and interacting gases. Finally, we extend the theory of symplectic Hamiltonian dynamics to describe (a) the free expansion of the ideal gas which involves irreversible generation of entropy, and (b) a symplectic port-Hamiltonian framework for the ideal gas which is exemplified through two problems, namely, the problem of isothermal expansion against a piston and that of heat transfer between a heat bath and the gas via a thermal conductor.",

      "abstract": "Developing high-fidelity digital twin models for electric spindles requires rigorously predicting the coupled thermal-vibration dynamics, where friction-induced heat actively drives parameter drift such as thermal stiffening and viscosity reduction. While structure-preserving frameworks like Port-Hamiltonian Neural Networks and Dissipative Hamiltonian Neural Networks excel in energy-based modeling, they predominantly treat dissipation via resistive ports or energy sinks, implicitly assuming an isothermal environment, failing to capture the reciprocal thermo-mechanical feedback, leading to substantial errors in vibration predictions. To bridge this gap, we propose a Physics-Informed Thermodynamical Hybrid Modeling Method based on the GENERIC formalism and the dissipative Hamiltonian dynamics. A Thermodynamical Hamiltonian Neural Network (THNN) is introduced to identify temperature-dependent constitutive parameters within a thermodynamically consistent physical model, rigorously tracking the conversion of dissipated mechanical work into entropy and temperature evolution and thereby closing the thermo-mechanical loop by design. Through a comprehensive proof-of-concept validated under diverse benchmark scenarios, including noise robustness and parameter sensitivity analyses, we demonstrate that THNN reduces the MAE by 44.1% compared to state-of-the-art baselines while maintaining strict adherence to the First and Second Laws of Thermodynamics. The compact architecture (4.9 K parameters) achieves superior accuracy through physics-informed structural constraints rather than model capacity, establishing a methodological approach for vibration prediction of electric spindles.",

      "abstract": "Motion control design plays a crucial role in autonomous vehicles. Mainly, these systems operate in conditions of under-actuation, which make the control a serious task especially in presence of practical constraints. The main objective within this paper is to ensure the tracking of 3D reference trajectory overcoming some of the issues related to the control of multi-rotor vehicles (such as underactuation, robustness, limited power, accuracy, overshoot, etc.). Therefore, a control scheme for Vertical Take Off and Landing (VTOL) multi-rotor Unmanned Aerial Vehicle (UAV) is designed, applying the Interconnection and Damping Assignment-Passivity Based Control (IDA-PBC) technique. As reference model based technique, the control specifications are readily met by fixing a desired dynamic model, which is a major advantage of the technique. Moreover, a port −controlled Hamiltonian representation is exploited in order to point out the physical properties of the system such as its internal energy. This latter is exploited, as a fitness function for an optimization algorithm, in order to decrease the consumed energy especially at the take-off step and allows the tuning of the controller parameters. The numerical simulations have shown satisfactory results that support the claims using nominal system model or disturbed model. The designed controller has been implemented on a real vehicle for which one demonstrates, in an indoor area manipulation, the effectiveness of the proposed control strategy.",

The considered models are isotropic Oseen equations where the viscosity acts uniformly in all directions and anisotropic Oseen-type equations with different viscosity directions. The hypocoercivity index is determined (if it exists) and it is shown that similar to the finite dimensional case of ordinary differential equations and differential-algebraic equations it characterizes its decay behavior.",

      "abstract": "The spectral theory for operator pencils and operator differential-algebraic equations is studied. Special focus is laid on singular operator pencils and three different concepts of singularity of operator pencils are introduced. The concepts are analyzed in detail and examples are presented that illustrate the subtle differences. It is investigated how these concepts are related to uniqueness of the underlying algebraic-differential operator equation, showing that, in general, classical results known from the finite dimensional case of matrix pencils and differential-algebraic equations do not prevail. The results are then studied in the setting of structured operator pencils arising in dissipative differential-algebraic equations. Here, unlike to the general infinite-dimensional case, the uniqueness of solutions to dissipative differential-algebraic operator equations is closely related to the singularity of the pencil.",

These equations have a Hamiltonian structure with a bilinear Poisson bracket, and as a consequence the phase-space structure, “mass” and energy are preserved. We discretize the bilinear Poisson bracket in each element with discontinuous elements and introduce numerical fluxes via integration by parts while preserving the skew-symmetry of the bracket. This automatically results in a mass and energy conservative discretization. When combined with a symplectic time integration method, energy is approximately conserved and shows no drift. For comparison, the discontinuous Galerkin method for this problem is also used. A variety numerical examples is shown to illustrate the accuracy and capability of the new method.",

      "abstract": "Reduced basis methods are popular for approximately solving large and complex systems of differential equations. However, conventional reduced basis methods do not generally preserve conservation laws and symmetries of the full order model. Here, we present an approach for reduced model construction, that preserves the symplectic symmetry of dissipative Hamiltonian systems. The method constructs a closed reduced Hamiltonian system by coupling the full model with a canonical heat bath. This allows the reduced system to be integrated with a symplectic integrator, resulting in a correct dissipation of energy, preservation of the total energy and, ultimately, it helps conserving the stability of the solution. Accuracy and stability of the method are illustrated through the numerical simulation of the dissipative wave equation and a port-Hamiltonian model of an electric circuit.",

      "abstract": "We introduce a reduced order model (ROM) methodology for inverse electromagnetic wave scattering in layered lossy media, using data gathered by an antenna which generates a probing wave and measures the time resolved reflected wave. We recast the wave propagation problem as a passive infinite-dimensional dynamical system, whose transfer function is expressed in terms of the measurements at the antenna. The ROM is a low-dimensional dynamical system that approximates this transfer function. While there are many possible ROM realizations, we are interested in one that preserves passivity and in addition is: (1) data driven (i.e., is constructed only from the measurements) and (2) it consists of a matrix with special sparse algebraic structure, whose entries contain spatially localized information about the unknown dielectric permittivity and electrical conductivity of the layered medium. Localized means in the intervals of a special finite difference grid. The main result of the paper is to show with analysis and numerical simulations that these unknowns can be extracted efficiently from the ROM.",

      "abstract": "This paper is on the construction of structure-preserving, online-efficient reduced models for the barotropic Euler equations with a friction term on networks. The nonlinear flow problem finds broad application in the context of gas distribution networks. We propose a snapshot-based reduction approach that consists of a mixed variational Galerkin approximation combined with quadrature-type complexity reduction. Its main feature is that certain compatibility conditions are assured during the training phase, which make our approach structure-preserving. The resulting reduced models are locally mass conservative and inherit an energy bound and port-Hamiltonian structure. We also derive a wellposedness result for them. In the training phase, the compatibility conditions pose challenges, we face constrained data approximation problems as opposed to the unconstrained training problems in the conventional reduction methods. The training of our model order reduction consists of a principal component analysis under a compatibility constraint and, notably, yields reduced models that fulfill an optimality condition for the snapshot data. The training of our quadrature-type complexity reduction involves a semi-definite program with combinatorial aspects, which we approach by a greedy procedure. Efficient algorithmic implementations are presented. The robustness and good performance of our structure-preserving reduced models are showcased at the example of gas network simulations.",

      "abstract": "In this paper, we present discontinuous Galerkin (DG) finite element discretizations for a class of linear hyperbolic port-Hamiltonian dynamical systems. The key point in constructing a port-Hamiltonian system is a Stokes-Dirac structure. Instead of following the traditional approach of defining the strong form of the Dirac structure, we define a Dirac structure in weak form, specifically in the input-state-output form. This is implemented within broken Sobolev spaces on a tessellation with polyhedral elements. After that, we state the weak port-Hamiltonian formulation and prove that it relates to a Poisson bracket. In our work, a crucial aspect of constructing the above-mentioned Dirac structure is that we provide a conservative relation between the boundary ports. Next, we state DG discretizations of the port-Hamiltonian system by using the weak form of the Dirac structure and broken polynomial spaces of differential forms, and we provide a priori error estimates for the structure-preserving port-Hamiltonian discontinuous Galerkin (PHDG) discretizations. The accuracy and capability of the methods developed in this paper are demonstrated by presenting several numerical experiments.",

      "abstract": "A new formulation for the modular construction of flexible multibody systems is presented. By rearranging the equations for a flexible floating body and introducing the appropriate canonical momenta, the model is recast into a coupled system of ordinary and partial differential equations in port-Hamiltonian (pH) form. This approach relies on a floating frame description and is valid under the assumption of small deformations. This allows including mechanical models that cannot be easily formulated in terms of differential forms. Once a pH model is established, a finite element based method is then introduced to discretize the dynamics in a structure-preserving manner. Thanks to the features of the pH framework, complex multibody systems could be constructed in a modular way. Constraints are imposed at the velocity level, leading to an index 2 quasilinear differential-algebraic system. Numerical tests are carried out to assess the validity of the proposed approach.",

      "abstract": "Multibody dynamics simulation plays an important role in various fields, including mechanical engineering, robotics, and biomechanics. Setting up computational models however becomes increasingly challenging as systems grow in size and complexity. Especially the consistent combination of models across different physical domains still requires significant effort. This motivates the study of formal languages that enable a compositional approach to modeling multiphysical systems with basic guarantees. The paper shows how multibody systems, or more precisely assemblies of rigid bodies connected by lower kinematic pairs, can be described as Exergetic Port-Hamiltonian Systems (EPHS). The EPHS modeling language features a straightforward graphical syntax for expressing the energy-based interconnection of hierarchically nested subsystems. This reduces cognitive load and facilitates clearer communication among experts, nonexperts, and computational tools. Hierarchical nesting of systems enables ion of lower-level details and promotes the reuse of models at different levels of complexity. At the lowest level, there are three basic kinds of systems, representing energy storage and reversible/irreversible energy exchange. The structured approach guarantees fundamental properties of macroscopic systems, such as conservation of energy and nonnegative entropy production. In combination with the compositional syntax, this makes building and modifying models simpler and less error-prone.",

      "abstract": "We propose a new, port-Hamiltonian formulation for the highly nonlinear dynamics of planar geometrically exact beams, which are amenable to arbitrary large deformations and rotations. A structure-preserving spatial and temporal discretization procedure - using mixed finite elements and second-order time-stepping methods - is proposed. It is observed that the present approach is objective, locking-free and provides an exact discrete representation of the energy and angular momentum balance. By comparing the approach to a classical displacement-based scheme from the literature it is shown that the port-Hamiltonian formulation paves new ways for the design of energy-momentum schemes in computational mechanics. Numerical examples underline the applicability to flexible multibody systems and beneficial numerical performance.",

      "abstract": "The main focus of this work is control of large overall motion of (highly) flexible Reissner beam that can represent in geometrically exact manner large displacements, large rotations and large strains. This nonlinear control problem is cast in distributed port-Hamiltonian framework, extending the previous works (Duindam et al. in Modeling and Control of Complex Physical Systems: The Port-Hamiltonian Approach, Springer, Berlin, 2009 ) dealing with finite dimensional systems (such as rigid components of multibody system interconnected with flexible joints) to infinite dimensional system with Hamiltonian density (Ljukovac et al. in Int. J. Numer. Methods Eng. 126, 2025 ). The nonlinear control is performed by defining the desired state of the flexible system through energy-shaping of distributed port-Hamiltonian, previously introduced for lumped-parameter system (Ortega et al. in IEEE Control Syst. Mag. 21:18–33, 2001 ; Brogliato et al. in Dissipative Systems Analysis and Control: Theory and Aplications, Springer, Cham, 2020 ). We first show how to perform the energy shaping for internal energy density by bringing the flexible beam with large overall motion into deformed configuration that is in static equilibrium, which is also the closest to the desired configuration of Reissner beam after large overall motion. We then show how to perform the energy shaping for kinetic energy, with the illustration provided for the choice of uniform rotational motion, which also requires the corresponding choice of internal energy defined by Casimir functional (Marsden et al. in Hamiltonian Reduction by Stages, Springer, Berlin, 2007 ). We finally discuss different procedures for damping injection that will stabilize the system to configurations with desired Hamiltonian, including viscous damping, frictional damping and energy decaying of high frequency modes for Reissner nonlinear beam. The results of illustrative numerical simulations of large overall motion of (very) flexible geometrically exact beam confirm the good performance of the proposed approach.",

First, we propose a new error bound which holds for both types of networks. Then, we numerically investigate some alternative activation functions in terms of prediction accuracy. The numerical results show the potential of the approaches when compared to the standard neural networks in the transient regime.",

      "abstract": "A novel nonlinear control scheme of induction motor (IM) is presented based on state error port-controlled Hamiltonian (PCH) systems and energy-shaping (ES) principle. The PCH model of IM system is established. Using interconnection assignment and damping injection method, the desired state error PCH structure is assigned to the closed-loop IM system by the ES principle. The controllers are designed when the load torque is known and unknown, respectively. A load torque estimator is developed in the presence of the load torque disturbance. Moreover, an observer is proposed to estimate the unknown load torque. The stability of the closed-loop system is also verified. Finally, speed regulation of the IM drive system is implemented based on space vector pulse-width modulation technology. The simulation results show that the system has good load disturbance attenuation and speed tracking performances.",

Once the desired Hamiltonian function is chosen, if the desired damping matrix is large enough, the convergence speed of the control law asymptotically stabilizing the PH system works more quickly. On the other hand, the desired Hamiltonian function can be replaced by a new desired energy function, which is also effective in energy-shaping. Finally, a three-phase synchronous generator example is given to show the correctness of the above contents.",

      "abstract": "A novel method of energy-shaping and integral control is proposed for the three-tank liquid level system. The mathematical model of the three-tank liquid level system is established based on port-controlled Hamiltonian (PCH) systems and mass balance principle. The three-tank liquid level system PCH controller is designed by means of interconnection assignment and damping injection and energy-shaping. The desired equilibrium point is also determined. The stability of the liquid level system is analyzed based on the passivity-based control theory. The integral control is added to eliminate the steady-state errors of the liquid level system. Moreover, simulation and experiment test are also carried out based on the laboratory experiment platform. The results prove that the proposed control method has good dynamic and steady state performances.",

      "abstract": "Many industry applications of teleoperating cyber-physical system (TCPS) require operator and slave to keep state synchronization on the shared information. However, the cyber-constrained property of TCPS makes it challenging to achieve such a synchronization. This paper is concerned with a state synchronization problem for TCPS, subjected to time-varying communication delay in cyber channels. A proportional-derivative (PD) controller with dynamic gains is designed to enforce the state synchronization of master and slave robots. Particularly, the gains are in the form of incremental rates, which can be dynamically adjusted by the delayed inputs. By introducing an appropriate state transformation, the dynamics of master and slave robots are rearranged as port-Hamiltonian systems, through which the state synchronization is converted into a stabilization problem of the augmented system. Meanwhile, stability conditions are given to show that the proposed synchronization controller can stabilize the closed-loop TCPS. Finally, simulation and experiment results are performed to show the validity of our proposed method. It is demonstrated that the adjustable gain-based synchronization controller can improve the dynamic and steady-state performance of TCPS by comparing with the traditional PD controllers.",

      "abstract": "In this paper, the locally fixed-time and globally fixed-time stabilization problems for the port-Hamiltonian (PH) systems via the interconnection and damping assignment passivity-based control technique are discussed. The definitions of fixed-time stability region (or region of attraction) and fixed-time stability boundary are given in this paper. From this starting point, the sufficient condition of globally fixed-time attractivity of a prespecified locally fixed-time stability region is obtained. Combining the locally fixed-time stability and the globally fixed-time attractivity of a prespecified locally fixed-time stability region, the globally fixed-time stabilization problem for PH system is effectively solved. Furthermore, the globally fixed-time control scheme independent of locally fixed-time stability region has also been derived by constructing a novel Lyapunov function. A illustrative example shows that the results obtained in this paper work very well in fixed-time control design of PH systems.",

      "abstract": "The problem of controlling the relative position and velocity in multi-spacecraft formation flying in the planetary orbits is an enabling technology for current and future research. This paper proposes a family of tracking controllers for different dynamics of Spacecraft Formation Flying (SFF) in the framework of port-Hamiltonian (pH) systems through application of timed Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC). The leader–multi-follower architecture is used to address this problem. In this regard, first we model the spacecraft motion in the pH framework in the Earth Centered Inertial frame and then transform it to the Hill frame which is a special local coordinate system. By this technique, we may present a unified structure which encompasses linear/nonlinear dynamics, with/without perturbation. Then, using the timed IDA-PBC method and the contraction analysis, a new method for controlling a family of SFF dynamics is developed. The numerical simulations show the efficiency of the approach in two different cases of missions.",

      "abstract": "This paper investigates the model-based nonlinear control of a class of soft continuum pneumatic manipulators that bend due to pressurization of their internal chambers and that operate in the presence of disturbances. A port-Hamiltonian formulation is employed to describe the closed loop system dynamics, which includes the pressure dynamics of the pneumatic actuation, and new nonlinear control laws are constructed with an energy-based approach. In particular, a multi-step design procedure is outlined for soft continuum manipulators operating on a plane and in 3D space. The resulting nonlinear control laws are combined with adaptive observers to compensate the effect of unknown disturbances and model uncertainties. Stability conditions are investigated with a Lyapunov approach, and the effect of the tuning parameters is discussed. For comparison purposes, a different control law constructed with a backstepping procedure is also presented. The effectiveness of the control strategy is demonstrated with simulations and with experiments on a prototype. To this end, a needle valve operated by a servo motor is employed instead of more sophisticated digital pressure regulators. The proposed controllers effectively regulate the tip rotation of the prototype, while preventing vibrations and compensating the effects of disturbances, and demonstrate improved performance compared to the backstepping alternative and to a PID algorithm.",

      "abstract": "This work investigates the tracking control problem for underactuated mechanical systems. To this end, we develop an extension of the dynamic tube Model Predictive Control (MPC) approach by combining an MPC design, an ancillary energy shaping controller constructed with the Interconnection and Damping Assignment Passivity-Based Control methodology, and an analytical expression of the dynamic tube. In addition, we extend the proposed approach by including the adaptive compensation of a class of unknown disturbances. The stability analysis is presented by employing a Lyapunov approach. The effectiveness of the proposed controller is demonstrated with simulations on two underactuated systems: a two-mass-spring-damper system with uncertain damping and either linear or nonlinear spring; an inertia-wheel-pendulum with unmodeled disturbances.",

      "abstract": "This article address a novel adaptive error port controlled Hamiltonian scheme for nonlinear systems with parameters uncertainty and external disturbances. Considering the input saturation phenomenon in real complex systems, a new smooth saturation function is used to deal with the limitations between the control signal and the actuator. The adaptive control technique is introduced to resolve the influence of model parameters uncertainty, and the nonlinear disturbance observer (NDO) is utilized to address external disturbances in real complex systems. Furthermore, a novel NDO-based adaptive error port controlled Hamiltonian (EPCH-NDO) strategy with the smooth switching gain optimization control technique is presented to enhance the accuracy of position tracking control for the target. Finally, the permanent magnet synchronous motor system is adopted to verify the proposed scheme. A large amounts of experiment results indicate that the proposed adaptive EPCH-NDO control strategy has perfect control performances compared with PI and port-controlled Hamiltonian based on load torque estimator methods.",

The main objective of this paper is the stabilization of under-actuated non-separable Port-controlled Hamiltonian (PCH) systems with an inertia matrix dependent of the unactuated coordinates, where the control input is affected by time-varying matched external disturbances. The proposed methodology adds an extension in the system coordinates, such that the system’s closed-loop stability and its PCH structure are preserved despite the presence of time-varying disturbances. The theoretical results are applied to an overhead crane and illustrated through numerical simulations.",

      "abstract": "In musical acoustics, the production of sound is usually described by the nonlinear interaction of the musician with a resonator (the instrument). For example a string (resonator) can be bowed or hit by a piano hammer (nonlinear interactions). The aim of this paper is to provide a stable (passive-guaranteed) simulation of such interaction systems. Our approach consists in first defining a generic passive-guaranteed structure for the interaction (finite dimensional) and for the resonator (infinite dimensional) and second constructing a generic procedure for the discretization of the resonator. This is achieved in the Port-Hamiltonian systems framework that decomposes a physical model into a network of energy-storing components, dissipative components and inputs-outputs, thus guaranteeing the passivity of the proposed models. Finally, a well established structure preserving time discretization method is used to provide numerical models which prove to fulfill a discrete power balance, hence the numerical stability. This generic procedure is applied to the sound synthesis of a bowed string and of a string hit by a piano hammer.",

      "abstract": "The adaptive tracking control for nonlinear systems often relies on stabilizing error dynamics, and the majority of these methods only achieve asymptotic tracking. However, since the time-varying feature of error system, it is challenging to construct a suitable Lyapunov function to accomplish the controller design and stability analysis. To tackle above limitations, an adaptive exponential tracking control strategy is proposed to port-Hamiltonian system (PHS) under the parameter uncertainties. First, a tracking controller is designed that can preserve the structural characteristics of closed-loop PHS by utilizing the timed Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) method. Then using the contraction method to design a differential energy function, the parameter update law of the PHS is obtained and the contractility of the closed-loop system is proved by leveraging the structure properties of PHS. Moreover, the exponential decay rate of tracking controllers is provided and the impact of parameters on system performance is analyzed. The proposed method not only handles time-varying and time-invariant systems in a unified way but also has the advantages of easier energy function construction and relatively simpler stability analysis than the conventional Lyapunov method. Finally, to validate the effectiveness and robustness of proposed tracking strategy, comparative simulations and experiments are performed on uncertain mechanical systems.",

By integrating a coordination controller, the SMC enhances responsiveness in transient state, while the PCH control ensures stability in steady state. Together, they collectively achieve MPPT control for FC-DFIG systems. The effectiveness and advantages of the proposed control strategy are validated through simulation and experiment.",

      "abstract": "This work presents a novel formulation and numerical strategy for the simulation of geometrically nonlinear structures. First, a non-canonical Hamiltonian (Poisson) formulation is introduced by including the dynamics of the stress tensor. This framework is developed for von-Kármán nonlinearities in beams and plates, as well as geometrically nonlinear elasticity with Saint-Venant material behavior. In the case of plates, both negligible and non-negligible membrane inertia are considered. For the former case the two-dimensional elasticity complex is leveraged to express the dynamics in terms of the Airy stress function. The finite element discretization employs a mixed approach, combining a conforming approximation for displacement and velocity fields with a discontinuous stress tensor representation. A staggered, linear implicit time integration scheme is proposed, establishing connections with existing explicit-implicit energy-preserving methods. The stress degrees of freedom are statically condensed, reducing the computational complexity to solving a system with a positive definite matrix. The integration strategy preserves energy and angular momentum exactly. The methodology is validated through numerical experiments on the Duffing oscillator, a von-Kármán beam, and a column undergoing finite deformations. Comparisons with fully implicit energy-preserving method and the leapfrog scheme demonstrate that the proposed approach achieves superior accuracy while maintaining energy stability. Additionally, it enables larger time steps compared to explicit schemes and exhibits computational efficiency comparable to the leapfrog method.",

      "abstract": "We employ a port-Hamiltonian approach to model nonlinear rigid multibody systems subject to both position and velocity constraints. Our formulation accommodates Cartesian and redundant coordinates, respectively, and captures kinematic as well as gyroscopic effects. The resulting equations take the form of nonlinear differential-algebraic equations that inherently preserve an energy balance. We show that the proposed class is closed under interconnection, and we provide several examples to illustrate the theory.",

To ensure finite-time stability (FTS) of the closed-loop SNPHS and further achieve finite-time contractive stability (FTCS), we develop a switching state-feedback (SSF) controller together with two trade-off-based mode-dependent average dwell-time (MDADT) switching schemes. FTC stabilization conditions are then derived for both SNPHSs and the associated SNSs. Moreover, to attain $$\\mathcal {H}_\\infty $$ H ∞ FTCS performance, we introduce the maximum ratio of the activation time of unstable modes and, together with the proposed trade-off-based MDADT schemes, sufficient conditions on $$\\mathcal {H}_\\infty $$ H ∞ FTCS control are also established for both SNPHSs and the associated SNSs via the SSF control design. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed results.",

      "abstract": "This paper proposes a modular, efficient, and stable numerical approach based on the port-Hamiltonian (pH) framework for the simulation of rigid-flexible multibody dynamics. The proposed method resolves the strongly nonlinear rigid-flexible coupling characteristics exhibited by variable-topology flexible multibody systems undergoing high-speed rotation and large spatial maneuvering, and enables the efficient marching of numerically stiff problems faced by traditional methods. By constructing a unified multi-domain energy description framework based on port-Hamiltonian theory, standardized modeling of system dynamic behavior is achieved. Model smoothing techniques are employed for model denoising, effectively overcoming the stiff problems. Furthermore, built upon the Component-Level Co-rotational (C-CR) finite element formulation, the method combines the symplectic Euler midpoint (SEM) scheme with the Component-Based Enhanced Solution (CES) strategy, enabling the efficient resolution of large-scale nonlinear equations while preserving energy conservation properties in long-term numerical simulations. Numerical simulations show that the proposed method exhibits significant advantages in both numerical stability and computational efficiency, providing a novel framework for eVTOL aircraft simulation, design, and control.",

To solve the H _∞ control problem, the energy function of a Hamiltonian system is shaped to such a form that could be a candidate solution of HJI inequality. Next, the energy function is shaped as a candidate of control ISS-Lyapunov function, and then the input-to-state stabilization of port-controlled Hamiltonian systems is achieved. Some easily verifiable sufficient conditions are presented.",

      "abstract": "This paper investigates parallel simultaneous stabilization (PSS) of a set of multi-input nonlinear Port-Controlled Hamiltonian (PCH) systems subject to actuator saturation (AS), and proposes a number of results on the design of PSS controllers for the PCH systems with AS. Firstly, the case of two PCH systems with AS is studied. Exploring the special property of the saturation nonlinearity and the structural properties of dissipative Hamiltonian system, the two systems are combined to generate an augmented PCH system, with which some results on the control design are then obtained. When there are external disturbances in the two systems, a robust PSS controller is designed for the systems. Secondly, the case of more than two PCH systems with AS is investigated, and several new results are proposed for the PSS problem. Finally, two illustrative examples are presented to show that the stabilization controllers obtained in this paper work very well.",

A γ -dissipative inequality is established by using a proper control law and a storage function. Then based on the Razumikhin stability theorem, a sufficient condition is proposed for the asymptotically stability of the closed-loop system. Finally, the authors investigate the case that there are time-invariant uncertainties belonging to some convex bounded polytypic domain and an L _2 disturbance attenuation control law is proposed. Study of illustrative example with simulation shows that the presented method in this paper works very well in the disturbance attenuation of time-delay Hamiltonian systems.",

Firstly, by exploiting the Hamiltonian structural properties, a proper form of the Hamiltonian function is obtained, based on which a finite-time stability criterion is then presented for a class of Hamiltonian systems. Secondly, using the obtained stability criterion and the so-called “energy shaping plus damping injection” technique, the continuous finite-time stabilization problem is studied for the PCH system, and several global stabilization results are provided. Finally, the continuous robust finite-time stabilization of the PCH system with external disturbances is investigated, and two results on designing global robust finite-time stabilizers are obtained. Study of several examples with numerical simulations shows that the control design approach developed in this paper works very well.",

Firstly, two parallel connecting PH systems subject to the AS and input delay are proposed. Secondly, a simultaneous stabilization control law is designed by a difference between the two feedback control laws containing the input delay. Thirdly, computing a Lyapunov-Krasovskii function assures the simultaneous stabilization of the above systems. Finally, simulation is given to show the correctness of the proposed contents.",

The scheme is based exclusively on passivity based control, without restricting the input frequency as it is done in field oriented control (FOC). A port-controlled Hamiltonian (PCH) model of the induction motor is deduced to make the interconnection and damping of energy explicit on the scheme. The proposed controller is validated under computational simulations and experimental tests using an inverter prototype.",

First, a desired potential energy introduced by a transitive Hamiltonian function is added to the original kinetic energy to yield a desired Hamiltonian function. Second, an asymptotically stabilized controller is designed based on a new matching equation with the obtained Hamiltonian function. Finally, a numerical example is given to show the effectiveness of the proposed method.",

Several conditions are established under which an ellipsoid is contractively invariant, and thus can be employed to find the biggest ellipsoid contained in the domain of attraction. It is shown that the proposed conditions can be expressed in the form of the linear matrix inequalities (LMIs) optimization problem with constraints. Study of an illustrative example shows that the proposed method works very well in estimating the domain of attraction for some classes of nonlinear PCH systems with AS.",

      "abstract": "In this paper, the asymptotic stability of Port-Hamiltonian (PH) systems with constant inputs is studied. Constant inputs are useful for stabilizing systems at their nonzero equilibria and can be realized by step signals. To achieve this goal, two methods based on integral action and comparison principle are presented in this paper. These methods change the convex Hamiltonian function and the restricted damping matrix of the previous results into a Hamiltonian function with a local minimum and a positive semidefinite matrix, respectively. Due to common conditions of Hamiltonian function and damping matrix, the proposed method asymptotically stabilizes more classes of PH systems with constant inputs than the existing methods. Finally, the validity and advantages of the presented methods are shown in an example.",

      "abstract": "Given an energy-dissipating port-Hamiltonian system, we characterise the exponential decay of the energy via the model ingredients under mild conditions on the Hamiltonian density $$\\mathcal{H}$$ . In passing, we obtain generalisations for sufficient criteria in the literature by making regularity requirements for the Hamiltonian density largely obsolete. The key assumption for the characterisation (and thus the sufficient criteria) to work is a uniform bound for a family of fundamental solutions for some non-autonomous, finite-dimensional ODEs. Regularity conditions on $$\\mathcal{H}$$ for previously known criteria such as bounded variation are shown to imply the key assumption. Exponentially stable port-Hamiltonian systems with densities in L _∞ only are also provided.",

      "abstract": "The conventional nonlinear control methods for induction motors have the problem of difficult observation of rotor current, and load disturbances make the dynamic performance of the system speed control unsatisfactory. A novel disturbance rejection control scheme with variable damping model based on port controlled Hamiltonian with dissipation is proposed. The induction drive is regarded as energy conversion device including mechanical and electrical ports. The Euler Lagrange equation of the closed-loop system is obtained by the output feedback to establish the energy shaping control method. The variable damping injection is introduced to improve the dynamic performance of the conventional control methods. The $$L_2$$ L 2 disturbance rejection controller is designed to enhance the load disturbance resistance performance of induction motors. The experimental results show that the proposed method can optimize the dynamic and steady-state performance of the induction drive control system and effectively meet the control requirements of the speed and torque under load disturbances.",

      "abstract": "This paper investigates the input disturbance suppression problem for nonlinear Port-Controlled Hamiltonian (PCH) system and presents a number of new results on the controllers design via the internal model approach. Different from the existing results on this topic we consider two cases. Firstly, the case of the disturbance generated from a linear Hamiltonian system acts through a channel other than the input channel is studied by adopting a method of decomposing the control into two parts and designing an internal model to zero the effect of the exogenous disturbance. Secondly, the case of the disturbance generated from a bounded nonlinear exosystem is studied by presenting a procedure of designing a nonlinear internal model to cancel the effect of the disturbance under two fundamental assumptions. Moreover, to further improve the suppression, a more effective internal model is also designed under less hypotheses. Finally, as an useful application, a corollary is presented by applying these results on PCH system to general nonlinear affine system. Simulations of a third-order synchronous generator model with disturbance generated from a nonlinear exosystem show the effectiveness of the designed internal model.",

Firstly, the adaptive stabilization problem is studied, and a control design method is developed by using both the dissipative Hamiltonian structural and saturated actuator properties. Secondly, for the case that there are both parametric uncertainties and external disturbances in the AS systems, an adaptive H _∞ control design approach is presented. Finally, study of an example of power systems with simulations shows that the adaptive controller proposed in this paper is effective.",

A simple condition is derived under which trajectories starting from the origin will remain inside an ellipsoid. The disturbance tolerance ability of the closed-loop system under a given feedback control law is measured by the size of this ellipsoid. Based on the above mentioned condition, the problem of disturbance tolerance can be expressed in the form of the linear matrix inequalities (LMIs) optimization problem with constraints. In addition, an H _∞ control approach is presented to attenuate the disturbances, and disturbance rejection ability in terms of L _2 gain is also determined by the solution of an LMI optimization problem. Study of an illustrative example with simulations shows the effectiveness of the methods proposed.",

      "abstract": "This study presents a design method for port-controlled Hamiltonian system, in which the nonlinear control is decomposed into the stabilization control at given equilibrium and additional L _2 adaptive control. The stabilization controller includes the simplified object model, which is the internal model controlling the conception expansion in nonlinear case. The errors arising from parameters and modelling are evaluated using the weighing matrix of the penalty function, which simplifies the design procedure of control. The L _2 adaptive control law is feedback control of the output errors with weighting matrix, which is the key character of the adaptive control. The proposed decomposing and simplifying method of the control law can be easily applied to investigate the higher order system. The procedure of control design and the issues associated with the application of control law are demonstrated by taking the hydro turbine generating system as an example. Simulation shows that the proposed method is very stable and robust.",

For the simplification, this work focuses on the nonlinear control law of the grid side converter (GSC) that is directly connected to the grid and affected during network disturbances. The proposed controller is designed through the analysis of PMSG GSC model from the passivity viewpoint in order to regulate the reference of the DC voltage and track the reference of the reactive current. The exponential stability of the equilibrium point of the error dynamics at the origin is guaranteed by using Lyapunov theory. Finally, the proposed method is validated through simulation. The simulation results show that the performance has smaller overshoot and faster convergence when the proposed method is used than when the conventional method is used.",

      "abstract": "This paper presents a new direct active and reactive power control (DPC) scheme for a three-phase grid connected voltage source inverter (VSI) based on the passivity viewpoint using the port-controlled Hamiltonian (PCH) system. The proposed controller consists of feedforward and feedback parts. The feedforward part (the reference inputs) is generated through the flatness of the dynamics of the VSI model, which makes the error dynamics in the form of PCH system. The nonlinear feedback part is designed to enhance the damping of the error dynamics by using its Lyapunov function. The proposed control method has an ability of the finite time reaching condition similar to sliding mode control (SMC). Moreover, the exponential stability and uniform performance are guaranteed over all operating points without need for reaching a certain manifold. The proposed method is validated by using an experiment through hardware-in-the-loop system with a digital signal processor. The experimental results for the proposed method are compared with those using SMC-DPC method. The proposed method significantly reduces the total harmonic distortion in the output current without deteriorating the transient response of the active and reactive powers. In addition, it provides robust performance against the line impedance variations and the grid voltage sag.",

Under two cases that the SNPCH system is subject to actuator saturation (AS) and the SNPCH system is without AS, a design approach for the switching robust $${{\\cal H}_\\infty}$$ H ∞ feedback controller is developed to attenuate the external disturbances. The sufficient conditions are established for $${{\\cal H}_\\infty}$$ H ∞ control of the corresponding closed-loop systems based on Hamilton-Jacobi inequality techniques. Furthermore, via the Hamiltonian realization method, the obtained results are applied to solve the $${{\\cal H}_\\infty}$$ H ∞ control for switched nonlinear affine systems with external disturbances. Finally, two numerical examples are presented to illustrate the effectiveness of the proposed $${{\\cal H}_\\infty}$$ H ∞ control methods.",

      "abstract": "In the literature of control theory, tracking control of port controlled Hamiltonian systems is generally achieved using canonical transformation. Closed form evaluation of state-feedback for the canonical transformation requires the solution of certain partial differential equations which becomes very difficult for nonlinear systems. This paper presents the application of neural networks for the canonical transformation of port controlled Hamiltonian systems. Instead of solving the partial differential equations, neural networks are used to approximate the closed-form state-feedback required for canonical transformation. Ultimate boundedness of the tracking and neural network weight errors is guaranteed. The proposed approach is structure preserving. The application of neural networks is direct and off-line processing of neural networks is not needed. Efficacy of the proposed approach is demonstrated with the examples of a mass-spring system, a two-link robot arm and an Autonomous Underwater Vehicle (AUV).",

      "abstract": "In this paper, we present two adaptive control approaches to handle uncertainties caused by parametric and modeling errors in a class of nonlinear systems with uncertainties. The methods use the Port-controlled Hamiltonian (PCH) modelling framework and the interconnection and damping assignment passivity-based control (IDA-PBC) control design methodology being the most effectively applicable method to such models. The methods explore an extension on the classical IDA-PBC by adopting the state-transformation, yielding a dynamic state-feedback controller that asymptotically stabilizes a class of underactuated mechanical systems and preserves the PCH structure of the augmented closed-loop system. The results are applied to the underactuated mechanical systems that are a class of mechanical systems with broad applications and are more interesting as well as challenging control problems within this context. The results are illustrated with numerical simulations applied to two underactuated robotic systems; the Acrobot and non-prehensile planar rolling robotic (disk-on-disk) systems.",

      "abstract": "This paper presents a passivity-based control strategy dealing with underactuated two-degree-of-freedom (2-DoF) mechanical systems. Such a methodology, which is based on the interconnection and damping assignment passivity-based control (IDA-PBC), rooted within the port-controlled Hamiltonian framework, can be applied to a very large class of underactuated 2-DoF mechanical systems. The main contribution, compared to the previous literature, is that the new methodology does not involve the resolution of any partial differential equation, since explicit solutions are given, while no singularities depending on generalised momenta are introduced by the controller. The proposed strategy is applied to two case studies: a) the stabilisation of a translational oscillator with a rotational actuator (TORA) system; b) the gait generation for an underactuated compass-like biped robot. The performances of the presented solution are evaluated through numerical simulations.",

The proposed observer is full order, and it is a copy of the original system dynamics with a corrective term. The suggested design methodology benefits from the port Hamiltonian framework properties. Based on a convenient assumption and exploiting the fact that the observer is structure preserving, the error between the plant and the observer converges exponentially to zero. The key tool in achieving our goal is the contraction analysis method. The observer design method is illustrated in the RLC circuit. We show that the presented approach may be applied in the inverted pendulum example. For both examples, some simulation results are presented.",

This observer design approach is based on the use of a powerful tool derived from continuum mechanics and differential geometry, known as contraction analysis. Under two verifiable assumptions, it is shown that error dynamics between the plant and the observer states converges exponentially to zero. Finally, our design method is applied to two physical systems arising from different domains: The DC motor and the RLC circuit.",

      "abstract": "The present work proposed a non-affine nonlinear air-supply subsystem model of proton exchange membrane fuel cell under a port-Hamiltonian framework. Furthermore, the control problem has been formulated in the port-Hamiltonian framework considering the balance between power consumption through the compressor and pressure distribution in the stack. Then, a novel passivity-based nonlinear control algorithm is developed via dynamic matching while preserving the port-Hamiltonian architecture. The main purpose of the control algorithm is to regulate the air-supply ratio and the excess oxygen in the optimal range. Finally, an explicit stability analysis of the closed-loop system is established, demonstrating that it is stable asymptotically in the domain of attraction. The simulation results demonstrate the effectiveness of the proposed control design approach.",

      "abstract": "A fractional frequency transmission system (FFTS) is the most competitive choice for long distance transmission of offshore wind power, while the Hexverter, as a newly proposed direct AC/AC converter, is an attractive choice for its power conversion. This paper proposes a novel control scheme characterizing the global stability and strong robustness of the Hexverter in FFTS applications, which are based on the interconnection and damping assignment passivity-based control (IDA-PBC) methodology. Firstly, the frequency decoupled model of the Hexverter is studied and then a port-controlled Hamiltonian (PCH) model is built. On this basis, the IDA-PB control scheme of the Hexverter is designed. Considering the interference of system parameters and unmodeled dynamics, integrators are added to the IDA-PB controller to eliminate the steady-state error. In addition, the voltage-balancing control is applied in order to balance the capacitor DC voltages to obtain a better performance. Finally, the simulation results and experimental results are presented to verify the effectiveness and superiority of the IDA-PB controller.",

Based on the mean-value theorem, multiple Lyapunov functions scheme, and universal approximation ability of fuzzy logic systems, a switching fuzzy adaptive controller is designed to ensure that all closed-loop signals are semiglobally uniformly ultimately bounded. Furthermore, the norm of an ideal weighting vector in fuzzy logic systems is taken as the estimation parameter instead of the elements of the weighting vector to reduce the dimension of adaptation laws. This switching controller can weaken the conservativeness brought by the application of the same controller for each subsystem. Finally, some examples are provided to verify the validity of the proposed approach.",

It is shown that there exists an equivalent relationship between the LQ-optimal control of boundary control systems and the output optimal control of the extended models. These results are applied to the port-Hamiltonian systems.",

      "abstract": "Unmanned Aerial Vehicles (UAVs) are increasingly deployed in complex, safety–critical missions where robust control under environmental uncertainties—such as in-flight icing and sensor noise—is essential. These disturbances degrade aerodynamic performance, flight stability, and tracking accuracy, challenging conventional control methods. This paper presents a novel control framework that synergistically integrates a fuzzy logic controller (FLC) with online adaptive tuning via Particle Swarm Optimization (PSO), embedded within a port-Hamiltonian (PH) modeling structure. The PH framework ensures physically consistent, energy-aware representation of UAV dynamics, enabling rigorous Lyapunov-based stability analysis and passivity guarantees. The key innovation lies in combining adaptive fuzzy control with an energy-based PH system model, which together enhance robustness against complex, nonlinear disturbances, such as icing and sensor noise, while simultaneously optimizing energy efficiency. Extensive simulations under realistic environmental and parametric uncertainties demonstrate significant improvements over traditional PID and standalone fuzzy controllers, including up to 85.7% reduction in altitude tracking error and 31.6% decrease in total energy consumption. Importantly, the approach maintains computational tractability by employing a simplified planar 3-DOF model focusing on translational and pitch dynamics—acknowledged as a main limitation and direction for future work. This integrated methodology advances the state-of-the-art by bridging adaptive intelligent control with rigorous physics-based modeling, providing a scalable and robust solution for next-generation autonomous UAVs operating safely in uncertain and adverse conditions.",

      "abstract": "In order to solve the problem of excessive damage to doubly fed induction generator (DFIG) system under the condition of unbalanced voltage, this paper presents an improved coordinated control strategy based on doubly-fed induction generator (DFIG) wind power system, which can solve these problems well. The innovation of this paper is that the parallel grid-side converter (PGSC) uses a passivity-based controller (PBC) based on the Port Control Hamiltonian Dissipation (PCHD) model. Not only can four different control goals be achieved, namely, constant voltage of DC bus voltage, grid-side active power without second harmonics, grid-side reactive power without second harmonics, and grid-side current without negative sequence component, but also to ensure that the balance of stator and rotor current without distortion, the DFIG output power and electromagnetic torque without pulsation. The proposed coordinated control strategy has the characteristics of not changing the control strategy of the rotor-side converter and avoiding complex high-order matrix. The experimental results on the software platform and the hardware platform show that the proposed coordinated control strategy has the advantages of fast response, strong anti-interference ability, high stability, less control parameters.",

      "abstract": "In this paper, a novel cooperative controller combining Linear Quadratic optimal control based on feedback linearization (LQ-FL) and state error port-Hamiltonian (EPH) with integral term is proposed for permanent magnet synchronous motor. Firstly, the LQ-FL is presented to ensure rapid dynamic performance, and the EPH method makes up for the shortcomings of the system in steady-state performance. The integral term is utilized to eliminate the position tracking steady-state error. Secondly, the Gaussian function is utilized to coordinate the two controllers and make them play their respective superiorities. Then, a nonlinear disturbance observer is used to resolve the total disturbance caused by parameter changes, modeling errors and external disturbance. Finally, the effectiveness and robustness of the proposed controller are verified by simulation and experiments.",

      "abstract": "In this work, we discuss the application of energy-based controller design for under-actuated soft robot manipulators. The continuous dynamics of the soft robot are modeled through the differential geometry of Cosserat beams. Using a finite-dimensional truncation, the system can be written as a reduced port-Hamiltonian model that preserves the passivity condition. Then, a model-based controller is introduced that produces a local minimizer of closed-loop potential energy for the desired end-effector configuration. The stabilizing control utilizes an energy-based approach and exploits the passivity of the soft robotic system. The effectiveness of the energy-based controller is demonstrated through extensive simulations of various soft robotic systems that share a resemblance with biology. All software and numerical studies are provided in an open-access SOROTOKI toolkit written in Matlab.",

      "abstract": "This paper presents a composite passivity-based controller for surface-type permanent magnet synchronous motors, which significantly enhances the anti-disturbance capabilities of speed tracking control against total disturbances, i.e., sudden load variations, modeling errors, and external uncertainties. First, a port-controlled Hamiltonian with a dissipation model is established for the permanent magnet synchronous motor. A field-oriented control framework based on the current inner loop is implemented via interconnection and damping assignment, offering a simple structure and clear physical interpretation. Second, an active disturbance rejection control with a load torque estimator is proposed to mitigate the total disturbance and reduce the burden on the linear extended state observer. Finally, the efficiency and robustness of the presented control method, which can achieve rapid dynamic tracking and excellent steady-state performance, are verified by an experimental platform using a DSPF28335 and MATLAB/Simulink. These results show that the system maintains high accuracy and stability under varying operating conditions.",

      "abstract": "The power generation of photovoltaic (PV) systems is significantly influenced by atmospheric conditions. The irregular energy exchange between the input (PV) and output (grid) sides can lead to oscillations in the DC-link voltage, which can adversely affect the stability and energy-harvesting efficiency of the system. To address this issue, a unified energy shaping control (UESC) strategy is proposed for grid-connected photovoltaic systems to improve the dynamic performance of the system. The traditional energy shaping control (ESC) strategy controls the DC-link voltage and grid-connected current independently, with the DC-link voltage controlled by a PI controller. However, the proposed UESC strategy is based on the unified port-controlled Hamiltonian (PCH) model in the synchronous reference frame for the entire PV system, which simultaneously controls the DC-link voltage and the grid-connected current. Simulation and experimental results demonstrate that the UESC strategy exhibits superior stability and dynamic performance compared to the traditional ESC strategy.",

      "abstract": "Conventional physics-based modeling techniques involve high effort, e.g., time and expert knowledge, while data-driven methods often lack interpretability, structure, and sometimes reliability. To mitigate this, we present a data-driven system identification framework that derives models in the port-Hamiltonian (pH) formulation. This formulation is suitable for multi-physical systems while guaranteeing the useful system theoretical properties of passivity and stability. Our framework combines linear and nonlinear reduction with structured, physics-motivated system identification. In this process, high-dimensional state data obtained from possibly nonlinear systems serves as input for an autoencoder, which then performs two tasks: (i) nonlinearly transforming and (ii) reducing this data onto a low-dimensional latent space. In this space, a linear pH system that satisfies the pH properties per construction is parameterized by the weights of a neural network. The mathematical requirements are met by defining the pH matrices through Cholesky factorizations. The neural networks that define the coordinate transformation and the pH system are identified in a joint optimization process to match the dynamics observed in the data while defining a linear pH system in the latent space. The learned, low-dimensional pH system can describe even nonlinear systems and is rapidly computable due to its small size. The method is exemplified by a parametric mass-spring-damper and a nonlinear pendulum example, as well as the high-dimensional model of a disc brake with linear thermoelastic behavior.",

We derive another Poisson structure for these equations by using general methods of symplectic geometry. The main ingredients in our construction are the symplectic structure on the co-adjoint orbits for the group of canonical transformations, and the symplectic structure for the phase space of the electromagnetic field regarded as a gauge theory. Our Poisson bracket satisfies the Jacobi identity, whereas Morrison's does not [37]. Our construction also shows where canonical variables can be found and can be applied to the Yang-Mills-Vlasov equations and to electromagnetic fluid dynamics.",

      "abstract": "Hamiltonian structures for 2- or 3-dimensional incompressible flows with a free boundary are determined which generalize a previous structure of Zakharov for irrotational flow. Our Poisson bracket is determined using the method of Arnold, namely reduction from canonical variables in the Lagrangian (material) description. Using this bracket, the Hamiltonian form for the equations of a liquid drop with a free boundary having surface tension is demonstrated. The structure of the bracket in terms of a reduced cotangent bundle of a principal bundle is explained. In the case of two-dimensional flows, the vorticity bracket is determined and the generalized enstrophy is shown to be a Casimir function. This investigation also clears up some confusion in the literature concerning the vorticity bracket, even for fixed boundary flows.",

The techniques are baseda on time-stepping with the generating function obtained as an approximate solution to the Hamilton-Jacobi equation, following ideas of deVogelaére, Channel,, and Feng. To accomplish this, the Hamilton-Jacobi theory is reduced from T∗G to g∗, where g is the Lie algebra of a Lie group G. The algorithms exactly preserve any additional conserved quantities in the problem. An explicit algorithm is given for any semi-simple group and in particular for the Euler equation of rigid body dynamics.",

      "abstract": "A Hamiltonian formulation of adiabatic free boundary inviscid fluid flow using only physical variables is presented in both the material and spatial formulation. Using the symmetry of particle relabeling, we derive the noncanonical Poisson bracket in Eulerian representation as a reduction from the canonical bracket in Lagrangian representation. When the free boundary of the fluid is given as the zero set of a function dragged along by the fluid flow, there is another bracket due to Abarbanel et al. [Physics of Fluids, (vol. 31), (2802), (1988)]. It is shown that this formulation «coverså the present one by proving that the natural restriction map is Poisson. It is also shown that the potential vortycity and the conserved quantities found by Abarbanel and Holm [Physics of Fluids (vol. 30), (3369), (1987)] are also conserved in the free boundary case.",

      "abstract": "This chapter deals with the design of a passivity-based controller for DC–DC converters by using a general representation for second-order converters, that is, buck, boost, buck-boost, and noninverting buck-boost converters. The main idea is to propose a dynamic structure for representing these converters by introducing some constants that allow compressing them into a unique representation. The general model obtained for these converters is a bilinear port-controlled Hamiltonian (PCH) representation, whose control input is multiplied by some state variables. This PCH structure allows designing a general proportional–integral controller with passive output that ensures the asymptotic stability for closed-loop operation in the Lyapunov sense. Numerical results demonstrate that the general proposed control scheme allows regulating the voltage output of all the converters with minimum errors and adequate responses during step changes in the reference signal.",

It an interesting example of an underactuated mechanical system (UMS) that is widely used in control theory research. The chapter begins with an introduction that highlights the importance of this system in both theoretical and practical applications. A detailed description of the system follows, emphasizing its key components and configurations. Real-life applications of the inertia wheel inverted pendulum, such as in robotics and balancing mechanisms, are also discussed. The core of the chapter focuses on the mathematical modeling of the system, starting with the derivation of the dynamic model. The open-loop behavior of the system is then analyzed, followed by the formulation of the port-Hamiltonian model. To facilitate control design, the system is linearized around its equilibrium point, providing insights into its controllability. Finally, the chapter presents the experimental setup and addresses the implementation issues, covering the mechanical and electrical components, the software used, and a detailed description of the evaluation scenarios conducted in real-time experiments.",

      "abstract": "Quite often, control theory takes the state space model of the to-be-controlled system for granted. In contrast, port-Hamiltonian systems theory bridges the gap between modeling and control of physical systems. It provides a unified framework for the modeling of complex multiphysics systems. At the same time it offers powerful tools for analysis and control by identifying the underlying physical structure, as reflected in, e.g., energy balance and other conserved quantities. This leads to control schemes that exploit the physical structure, instead of compensating for it. As a result, the derived control laws tend to be simple, physically interpretable, and robust with respect to physical parameter variations. In this paper, after introducing port-Hamiltonian systems, the focus is on 'control by interconnection' for set-point stabilization of nonlinear physical systems. Most of this theory is well-established, but novel developments using 'energy ports' instead of 'power ports' are also included.

      "abstract": "In rehabilitation robotics, control of energy flow is not merely a stability requirement but a therapeutic tool that shapes the quality and safety of human-robot interaction (HRI). The precise modulation of potential and kinetic energy within the coupled human–robot system governs how assistance is provided, how disturbances are rejected, and how patient effort is encouraged. Energy shaping approaches enable the controller to sculpt an artificial energy landscape anchored at a prescribed reference posture, so that restorative torques emerge naturally from the gradient of the shaped potential and disturbance-rich interactions are regulated within bounded, passive operating limits. This study presents a novel deep learning-based energy shaping framework for torque control in a three-degree-of-freedom (DOF) ankle rehabilitation robot. The proposed method is rooted in port-Hamiltonian mechanics. It employs interconnection and damping assignment-passivity-based control (IDA-PBC) to shape the energy landscape of the system, promoting practical stability and safe patient interaction. To address the limitations of static or heuristic energy shaping, we introduce a physics-informed data-driven approach in which the potential energy function is dynamically constructed through an Attention-Augmented Fourier Neural Operator (AFNO). This architecture learns mappings from spatiotemporal sensor data, including joint kinematics and interaction torques, to optimal shaping parameters that define the control energy field. The control strategy was experimentally validated on an ankle rehabilitation robot with ten healthy subjects (eight male, two female, aged 25–43), performing controlled movements across dorsiflexion/plantarflexion, inversion/eversion, and abduction/adduction. Experimental data confirmed that the shaped potential energy fields successfully guided joint trajectories toward the prescribed reference posture under disturbance-rich interaction conditions, while maintaining passivity and minimizing unnecessary energy expenditure.",

      "abstract": "The general dilemma faced in a conventional linear proportional–integral (PI) controller is to achieve the best transient performance (i.e. fast rise time and low overshoot level) at the same time. However, fast response is usually accompanied by high overshoot level. On the other hand, very stable control without overshoot is usually achieved at the expense of a more sluggish response to set point changes and load disturbances. Therefore, compromise between fast response and low overshoot level should be made. In this paper, to overcome these contradictions and limitations, nonlinear error shaping function (ESF) is introduced to amplify gain at low error level but reduce gain at high error level. Firstly, interconnection and damping structure for the closed-loop system composed of PI controller and first-order plant is revealed based on the port-controlled hamiltonian with dissipation (PCHD) formation. Secondly, passivity analysis is performed by the interconnection and damping assignment (IDA) passivity-based control (PBC) algorithm. In simulation studies, several nonlinear error shaping functions are examined and compared to verify performance improvements.",

A composite control method is developed by combining the damping injection and the nonlinear disturbance observer techniques together. A series of coordinate transformation is presented to transform the system with mismatched disturbance into matched disturbance system. By means of Lyapunov stability theorems, global stability analysis for the closed-loop Hamiltonian system is presented. It is shown that the system output is regulated to zero asymptotically in the presence of mismatched disturbance without larger overshoots and longer settling time caused by integral action. Study on two examples with simulation results demonstrates the effectiveness of the proposed control method.",

The approximate controllability and observability Gramians on the finite-time interval [ T 1 , T 2 ] ( 0 ≤ T 1 < T 2 < ∞ ) can be obtained by the shifted Legendre polynomials and the reduced port-Hamiltonian system is constructed by the union of dominant eigenspaces. Since the port-Hamiltonian system is square, the cross Gramian on the time interval [ T 1 , T 2 ] can also be approximated by using the shifted Legendre polynomials. Then, the truncated singular value decomposition of the approximate finite-time cross Gramian is carried out to obtain the projection matrix. Finally, the proposed methods are verified by two numerical examples.",

      "abstract": "In this note, Timoshenko beams with interior damping and boundary damping are studied from the viewpoints of control theory and numerical approximation. Especially, the uniform exponential stabilities of the beams are studied. The meaning of uniform exponential stability in this paper is two-fold: The first one is in the classical sense and also is concisely called exponential stability by many authors; The second one is that the semi-discretization systems, which are derived from an exponentially stable continuous beam by some semi-discretization schemes, are uniformly exponentially stable with respect to the discretized parameter. To investigate uniform exponential stability of continuous and discrete systems, five completely different methods, which are stability theory of port-Hamiltonian system, direct method of Lyapunov functional, perturbation theory of C 0 -semigroup, spectral analysis of unbounded operator and frequency standard of exponential stability for contractive semigroup, are involved. Especially, a new method, which is based on the frequency domain characteristics of uniform exponential stability of C 0 -semigroup of contractions, is established to verify the uniform exponential stability of semi-discretization systems derived from coupled system. The effectiveness of the numerical approximating algorithms is verified by numerical simulations.",

      "abstract": "In this contribution, we extend the hybridization framework for the Hodge Laplacian [Awanou et al. (2023) [16]] to port-Hamiltonian systems describing linear wave propagation phenomena. To this aim, a dual field mixed Galerkin discretization is introduced, in which one variable is approximated via conforming finite element spaces, whereas the second is completely local. The mixed formulation is then hybridized to obtain an equivalent formulation that can be more efficiently solved using a static condensation procedure in discrete time. The size reduction achieved thanks to the hybridization is greater than the one obtained for the Hodge Laplacian as the final system only contains the globally coupled traces of one variable. Numerical experiments on the 3D wave and Maxwell equations illustrate the convergence of the method and the size reduction achieved by the hybridization.",

      "abstract": "We study chaotic synchronization in a 5D Hindmarsh–Rose neuron model augmented with electromagnetic induction and a switchable memristive autapse. For two diffusively coupled identical neurons, we derive the transverse error dynamical system and analyze local synchronization via the linearized error system around the synchronization manifold. A quadratic Lyapunov function yields explicit sufficient conditions for (i) asymptotic stability when the memristive switching remains dissipative and (ii) practical stability with an explicit ultimate bound under non-dissipative switching. We complement this with a Hamiltonian-based viewpoint: a Helmholtz decomposition of the linearized error vector field provides a closed-form synchronization Hamiltonian and its rate identity. Numerical simulations corroborate convergence or ultimate boundedness of the synchronization errors and an overall decay of the synchronization Hamiltonian and its instantaneous rate toward zero after transients, and show consistent trends between Lyapunov- and Hamiltonian-based diagnostics across parameters. Finally, we propose the first port-Hamiltonian physics-informed neural network (pH-PINN) that learns this synchronization Hamiltonian and its rate from data while preserving conservative/dissipative structure, achieving close agreement with the analytical expressions.",

To show the practical relevance, we apply this interconnection to a model system of an actively cooled gas turbine blade. We also show that this interconnection relation behaves well with respect to a discretization in finite element space, ensuring its usability for practical applications.",

Numerical results for coupled mass–spring–damper chains illustrate the computational efficiency of the splitting methods compared to a straight-forward application of the implicit midpoint rule to the overall system.",

      "abstract": "The port-Hamiltonian framework is a structure-preserving modeling approach that preserves key physical properties such as energy conservation and dissipation. When subsystems are modeled as port-Hamiltonian systems (pHS) with linearly related inputs and outputs, their interconnection remains port-Hamiltonian. This paper introduces a systematic method for transforming coupled port Hamiltonian ordinary differential equations systems (pHODE) into a single monolithic formulation, and for decomposing a monolithic system into weakly coupled subsystems. The monolithic representation ensures stability and structural integrity, whereas the decoupled form enables efficient distributed simulation via operator splitting or dynamic iteration.",

      "abstract": "Electrochemical capacitors, called supercapacitors (SCs) or ultracapacitors, are devices conveniently used for embedded electrical energy management owing to their huge capacitance, low internal resistance and flexible control through power electronic conversion. This paper proposes a main power supply of hybrid Wind Generator (WG)–SC within the train station for feeding the traction onboard SC through specified limited feeding transit durations. Onboard SCs provide the train with the requested start–up self–energy. The hybrid WG–SCs system is an environmental–friendly source that enables the independency on national grid and guarantees an efficient bidirectional power transfer for energy management with enhanced dynamic performance. Therefore, the dynamic modelling and the experimental analysis of the modern hybrid WG–SCs used for managing the charge/discharge operation of SCs at Unity Power Factor (UPF) mode are presented. For this purpose, the Port–Controlled Hamiltonian (PCH) methodology is deduced and explicitly presented. Simulation results, via MATLAB™, reveal that the proposed PCH control methodology can be successfully implemented to ensure acceptable system dynamic behavior. Numerical results are validated with experimental measurements to investigate the significance of the PCH approach for the energy management operation in eco-tractions.",

      "abstract": "With the emergency of competitive markets as central operational mechanisms, the real-time market clearing results are used to determine the optimal power dispatch. It inevitably strengthens the coupling between the market update process and the physical response of the generators and networks. It necessitates the development of stability analysis for such coupled systems. Based on the primal–dual gradient method, an economic cybernetic model is established to simultaneously characterize the market operation and electromechanical power system dynamics. Inspired by modern control theory, the proposed dynamic model constructs a state space in which the actions of market participants are control signals, and the system states, such as nodal prices, bus voltages, and frequency, are treated as state variables. To promote the expandability, we also formulate the coupled dynamics in port-Hamiltonian form and provide detailed proof and sufficient conditions for its asymptotic stability by using properties of incremental passive systems. The whole transaction process implemented in a distributed manner aims at maximizing social welfare and frequency regulation when the economic-physical system reaches its equilibrium point.",

      "abstract": "This paper is concerned with the problem of H ∞ model reduction for the linear port-controlled Hamiltonian systems. The development includes both the continuous- and discrete-time cases. Some sufficient conditions are obtained for the existence of solutions in terms of linear matrix inequalities (LMIs) and a coupling non-convex rank constraint set. In addition, an explicit parametrization of the desired reduced-order model can be constructed if these conditions are satisfied. Furthermore, the conditions based on the strict LMIs without rank constraint are derived for the zeroth-order H ∞ approximation problem. Finally, the effectiveness of the proposed model reduction method is illustrated via a practical example.",

We propose a controller based on passivity theory with the aim of damping oscillations in a power system. Passivity-based control arises as a natural choice for hydro-turbine governing system since its open-loop dynamic has a port-Hamiltonian structure, which allows designing a controller that preserves the passive structure in closed-loop via interconnection and damping reassignment. The proposed controller considers the complete non-linear model of the system and guarantees global asymptotic stability in the sense of Lyapunov. Time-domain simulations demonstrate the robustness and proper performance of the proposed methodology under different operative conditions when is compared with the classical controllers.",

      "abstract": "The port-Hamiltonian formulation is a powerful method for modeling and interconnecting systems of different natures. In this paper, the port-Hamiltonian formulation in tensorial form of a thick plate described by the Mindlin–Reissner model is presented. Boundary control and observation are taken into account. Thanks to tensorial calculus, it can be seen that the Mindlin plate model mimics the interconnection structure of its one-dimensional counterpart, i.e. the Timoshenko beam. The Partitioned Finite Element Method (PFEM) is then extended to both the vectorial and tensorial formulations in order to obtain a suitable, i.e. structure-preserving, finite-dimensional port-Hamiltonian system (PHs), which preserves the structure and properties of the original distributed parameter system. Mixed boundary conditions are finally handled by introducing some algebraic constraints. Numerical examples are finally presented to validate this approach.",

      "abstract": "The mechanical model of a thin plate with boundary control and observation is presented as a port-Hamiltonian system (PHs 1 1 PHs stands for port-Hamiltonian systems. ), both in vectorial and tensorial forms: the Kirchhoff-Love model of a plate is described by using a Stokes-Dirac structure and this represents a novelty with respect to the existing literature. This formulation is carried out both in vectorial and tensorial forms. Thanks to tensorial calculus, this model is found to mimic the interconnection structure of its one-dimensional counterpart, i.e. the Euler-Bernoulli beam. The Partitioned Finite Element Method (PFEM 2 2 PFEM stands for partitioned finite element method. ) is then extended to obtain a suitable, i.e. structure-preserving, weak form. The discretization procedure, performed on the vectorial formulation, leads to a finite-dimensional port-Hamiltonian system. This part II of the companion paper extends part I, dedicated to the Mindlin model for thick plates. The thin plate model comes along with additional difficulties, because of the higher order of the differential operator under consideration.",

The model consists of the power preserving interconnection between two infinite dimensional systems describing the beam’s motion and deformation with a finite dimensional nonlinear system describing the dynamics of the actuated rotating joints. To derive the model, Timoshenko’s assumptions are made for the flexible beams. Using Hamilton’s principle, the dynamic equations of the system are derived and then written in the Port-Hamiltonian (PH) framework through a proper choice of the state variables. These so called energy variables allow to write the total energy as a quadratic form with respect to a state dependent energy matrix. The resulting model is shown to be a passive system, a convenient property for control design purposes.",

      "abstract": "With this contribution, we give a complete and comprehensive framework for modeling the dynamics of complex mechanical structures as port-Hamiltonian systems. This is motivated by research on the potential of lightweight construction using active load-bearing elements integrated into the structure. Such adaptive structures are of high complexity and very heterogeneous in nature. Port-Hamiltonian systems theory provides a promising approach for their modeling and control. Subsystem dynamics can be formulated in a domain-independent way and interconnected by means of power flows. The modular approach is also suitable for robust decentralized control schemes. Starting from a distributed-parameter port-Hamiltonian formulation of beam dynamics, we show the application of an existing structure-preserving mixed finite element method to arrive at finite-dimensional approximations. In contrast to the modeling of single bodies with a single boundary, we consider complex structures composed of many simple elements interconnected at the boundary. This is analogous to the usual way of modeling civil engineering structures which has not been transferred to port-Hamiltonian systems before. A block diagram representation of the interconnected systems is used to generate coupling constraints which leads to differential algebraic equations of index one. After the elimination of algebraic constraints, systems in input-state-output (ISO) port-Hamiltonian form are obtained. Port-Hamiltonian system models for the considered class of systems can also be constructed from the mass and stiffness matrices obtained via conventional finite element methods. We show how this relates to the presented approach and discuss the differences, promoting a better understanding across engineering disciplines. A Matlab framework is available on http://github.com/awarsewa/ph_fem/ to facilitate the application of the methods to different problems.",

      "abstract": "This article introduces a novel systematic methodology for modeling a class of multidimensional linear mechanical systems that directly allows to obtain their infinite-dimensional port-Hamiltonian representation. While the approach is tailored to systems governed by specific kinematic assumptions, it encompasses a wide range of models found in current literature, including ℓ-dimensional elasticity models (where ℓ = 1, 2, 3), vibrating strings, torsion in circular bars, classical beam and plate models, among others. The methodology involves formulating the displacement field using primary generalized coordinates via a linear algebraic relation. The non-zero components of the strain tensor are then calculated and expressed using secondary generalized coordinates, enabling the characterization of the skew-adjoint differential operator associated with the port-Hamiltonian representation. By applying Hamilton's principle and employing a specially developed integration by parts formula for the considered class of differential operators, the port-Hamiltonian model is directly obtained, along with the definition of boundary inputs and outputs. To illustrate the methodology, the plate modeling process based on Reddy's third-order shear deformation theory is presented as an example. To the best of our knowledge, this is the first time that a port-Hamiltonian representation of this system is presented in the literature.",

      "abstract": "Flexible multibody dynamics has been developed as an effective method for analyzing mechanical structures, wherein the Hamiltonian formulation draws attention for advantages such as the systematic handling of systems with varying mass. However, the utilization of the finite element method typically results in a large number of variables, which deteriorates computational efficiency. An effective method to reduce the number of variables (coordinates and canonical conjugate momentum) in Hamiltonian formulation needs to be presented. This paper proposes a novel reduced-order modeling of the Hamiltonian formulation based on the component mode synthesis method. A novel definition of momentum is proposed to construct the equation of motion. Compared with conventional Hamiltonian formulations, not only generalized coordinates but also momentum is reduced. By combining the absolute nodal coordinate formulation with the proposed formulation, it is applicable to analyze nonlinear structures with large deformation and rotations. Four numerical simulations were conducted to evaluate the performance of the proposed formulation, and calculation time reductions of 52.1 %, 83.6 %, 93.4 %, and 81.5 % were achieved. Overall, the proposed Hamiltonian formulation exhibits high calculation efficiency, good numerical stability, and high accuracy.",

      "abstract": "This article presents a systematic modeling methodology for deriving the infinite-dimensional port-Hamiltonian representation of geometrically nonlinear and hyperelastic systems, and a structure-preserving mixed FEM approach. The proposed methods provide a rigorous framework for obtaining the dynamic nonlinear partial differential equations governing these systems, ensuring that they are consistent with a Stokes–Dirac geometric structure. This structure is fundamental for modular multiphysics modeling and nonlinear passivity-based control. The modeling methodology is rooted in a total Lagrangian formulation, incorporating Green–Lagrange strains and second Piola–Kirchhoff stresses, where generalized displacements and strains define the interconnection structure. Using the generalized Hamilton's principle, infinite-dimensional port-Hamiltonian systems are systematically derived. To preserve the structure upon spatial discretization, a three-field mixed finite element approach is proposed, in which displacements, strains, and stresses are explicitly treated as independent variables to retain the port-Hamiltonian structure. The effectiveness of the framework is demonstrated through model derivation and simulations, using a geometrically nonlinear planar beam with Saint Venant–Kirchhoff material, and a compressible nonlinear 2D elasticity problem with a Neo-Hookean material model, as illustrative examples.",

      "abstract": "This paper presents a generalized energy-based modeling framework extending recent formulations tailored for differential–algebraic equations. The proposed structure, inspired by the port-Hamiltonian formalism, ensures passivity, preserves the power balance, and facilitates the consistent interconnection of subsystems. A particular focus is put on low-frequency power applications in electrical engineering. Stranded, solid, and foil conductor models are investigated in the context of the eddy current problem. Each conductor model is shown to fit into the generalized energy-based structure, which allows their structure-preserving coupling with electrical circuits described by modified nodal analysis. Theoretical developments are validated through a numerical simulation of an oscillator circuit, demonstrating energy conservation in lossless scenarios and controlled dissipation when eddy currents are present. The applicability of the methodology towards engineering applications is studied through a numerical simulation of a nonlinear three-phase transformer.",

      "abstract": "In this contribution, a finite element scheme to impose mixed boundary conditions without introducing Lagrange multipliers is presented for hyperbolic systems described as port-Hamiltonian systems. The strategy relies on finite element exterior calculus and domain decomposition to interconnect two systems with dual input-output behavior. The spatial domain is split into two parts by introducing an arbitrary interface. Each subdomain is discretized with a mixed finite element formulation that introduces a uniform boundary condition in a natural way as the input. In each subdomain the finite element spaces are selected from a finite element subcomplex to obtain a stable discretization. The two systems are then interconnected together by making use of a feedback interconnection. This is achieved by discretizing the boundary inputs using appropriate spaces that couple the two formulations. The final systems include all boundary conditions explicitly and do not contain any Lagrange multiplier. Time integration is performed using the implicit midpoint or Störmer-Verlet scheme. The method can also be applied to semilinear systems containing algebraic nonlinearities. The proposed strategy is tested on different examples: geometrically exact intrinsic beam model, the wave equation, membrane elastodynamics and the Mindlin plate. Numerical tests assess the conservation properties of the scheme, the effectiveness of the methodology and its robustness against shear locking phenomena.",

      "abstract": "This paper investigates the preservation of passivity in the discrete-time modeling of a class of port-Hamiltonian systems arising in power-electronic applications. We analyze the most commonly used discretization schemes and derive sufficient conditions under which each method preserves passivity. The results show, through passivity indicators and simulation studies, that the modified passive output obtained from the proposed framework preserves passivity, whereas the classical discrete-time passive output may violate it. For cases in which passivity is not inherently guaranteed, a systematic procedure to determine an admissible discretization step is provided. It is shown that the Exact, Backward Euler, Midpoint, and RK4 methods preserve passivity independently of the step size, while Forward Euler exhibits a maximum admissible step beyond which passivity is lost. Mathematical models are presented for applications in power electronics. However, the reader does not require specialized expertise in this area to reproduce results. The findings confirm that preserving passivity—rather than symplecticity—is the key requirement for the intended applications and that a rigorous analytical framework is necessary to ensure this property in discrete time.",

      "abstract": "This study proposes a novel adaptive integral controller integrated with the interconnection and damping assignment passivity-based control framework for underactuated mechanical systems, and applies it to tower cranes. First, an underactuated system model with uncertainties is constructed based on Port-controlled Hamiltonian structure. Subsequently, using a state transformation, an adaptive integral controller is designed to realize real-time estimation of unknown parameters and reduce steady-state errors. The stability of the closed-loop system under uncertainties is rigorously proven via the Lyapunov candidate function based on the Hamiltonian energy. Then, a constructive approach without additional parameter constraints is presented to obtain the solution of partial differential equations. Finally, the proposed controller is applied to an underactuated tower crane system, and the control parameters are determined by the pole placement method to reduce time and effort spent on parameter tuning. Experimental results demonstrate that, under the action of the proposed controller, the mean absolute tracking errors of the jib and the trolley remain within 0.9251 deg and 0.0175 m, and the mean absolute swing angles of the load are effectively suppressed within 0.1399 deg and 0.2239 deg, which fully complies with the performance specifications for industrial applications.",

      "abstract": "In this paper, we develop high-order splitting methods for linear port-Hamiltonian systems, focusing on preserving their intrinsic structure, particularly the dissipation inequality. Port-Hamiltonian systems are characterized by their ability to describe energy-conserving and dissipative processes, which is essential for the accurate simulation of physical systems. For autonomous systems, we introduce an energy-associated decomposition that exploits the system's energy properties. We present splitting schemes up to order six. In the non-autonomous case, we employ a port-based splitting. This special technique makes it possible to set up methods of arbitrary even order. Both splitting approaches are based on the properties of the commutator and ensure that the numerical schemes not only preserve the structure of the system but also faithfully fulfill the dissipation inequality. The proposed approaches are validated through theoretical analysis and numerical experiments.",

      "abstract": "In the simulation of differential-algebraic equations (DAEs), it is essential to employ numerical schemes that take into account the inherent structure and maintain explicit or hidden algebraic constraints. This paper focuses on operator splitting techniques for coupled systems and aims at preserving the structure in the port-Hamiltonian framework. The study explores two decomposition strategies: one considering the underlying coupled subsystem structure and the other addressing energy-associated properties such as conservation and dissipation. We show that for coupled index-1 DAEs with and without private index-2 variables, the splitting schemes on top of a dimension-reducing decomposition achieve the same convergence rate as in the case of ordinary differential equations. Additionally, we discuss an energy-associated decomposition for linear time-invariant port-Hamiltonian index-1 DAEs and introduce generalized Cayley transforms to uphold energy conservation. The effectiveness of both strategies is evaluated using port-Hamiltonian benchmark examples from electric circuits.",

      "abstract": "Discrete gradient methods are a powerful tool for the time discretization of dynamical systems, since they are structure-preserving regardless of the form of the total energy. In this work, we discuss the application of discrete gradient methods to the system class of nonlinear port-Hamiltonian differential-algebraic equations - as they emerge from the port- and energy-based modeling of physical systems in various domains. We introduce a novel numerical scheme tailored for semi-explicit differential-algebraic equations and further address more general settings using the concepts of discrete gradient pairs and Dirac-dissipative structures. Additionally, the behavior under system transformations is investigated and we demonstrate that under suitable assumptions port-Hamiltonian differential-algebraic equations admit a representation which consists of a parametrized port-Hamiltonian semi-explicit system and an unstructured equation. Finally, we present the application to multibody system dynamics and discuss numerical results to demonstrate the capabilities of our approach.",

      "abstract": "This paper proposes a novel approach to analyze and design the formation keeping control protocols for multiple underwater vehicles in the presence of communication faults and possible uncertainties. First, we formulate the considered vehicle model as the Port-controlled Hamiltonian form, and introduce the spring-damping system based formation control. Next, the dynamics of multiple underwater vehicles under uncertain relative information is reformulated as a network of Lur’e systems. Moreover, the agents under unknown disturbances generated by an external system are considered, where the internal model is applied to tackle the uncertainties, which still can be regulated as the Lur’e systems. In each case, the formation control is derived from solving LMI problems. Finally, a numerical example is introduced to illustrate the effectiveness of the proposed theoretical approach.",

      "abstract": "This work makes use of a passivity-based approach (PBA) and tools from Lyapunov theory to design a nonlinear controller for the asymptotic stabilization of a class of nonisothermal Continuous Stirred Tank Reactors (CSTR) around any desired stationary point. The convergence and stability proofs are derived in the port Hamiltonian framework. Asymptotic observers that do not require knowledge of reaction kinetics are also proposed for a system with incomplete state measurement. Numerical simulations are given to illustrate the application of the theoretical results to a CSTR with multiple steady states.",

      "abstract": "Increasing integration of renewable energy sources in the power grid leads to a complete re-thinking of its operation. This necessitates the consideration of new modeling and analysis approaches, which can serve as natural starting points for robust and scalable control and design strategies. In this ‘vision’ paper we will highlight two topics within the broad area of power networks: the modeling and analysis of the synchronous generator, and the modeling and analysis of power networks using the swing equation as an approximate model for the generator. In both cases we will discuss a port-Hamiltonian formulation, which reflects the underlying physics of power flow and energy storage. Although the port-Hamiltonian model of the synchronous generator reveals a clear structure it still poses fundamental challenges for its non-zero steady state stability analysis. It is shown how the swing equation can be directly deduced from the power balance of the port-Hamiltonian model of the synchronous generator. Under the phasor assumption, this leads to a port-Hamiltonian model of power networks of generators, which enables a straightforward stability analysis and provides a starting point for control.",

      "abstract": "In this paper we envision how to tackle a particularly challenging problem which presents highly interdisciplinary features, ranging from biology to engineering: the dynamic description and technological realisation of flapping flight. This document explains why, in order to gain new insights into this topic, we chose to employ port-Hamiltonian theory. We discuss how the physically unifying character of the framework is able to describe flapping dynamics in all its important aspects. The technological and theoretical challenges of flapping flight are discussed by considering the interplay between different topics. First of all, the formal conceptualisation of the problem is analysed. Second, the features and capabilities of port-Hamiltonian framework as the underneath mathematical language are presented. Subsequently, the discretisation of the resulting model by means of structure-preserving strategies is addressed. Once a reliable numerical model is available, we discuss how control actions can be computed based on high-level specifications aiming at increasing the flight performances. In the last part, the technological tools needed to validate experimentally the models and to equip a robotic bird prototype with the necessary sensing and actuation devices are discussed.",

      "abstract": "Controlling redundant manipulators in unstructured environments like agricultural settings is challenging due to high nonlinearities and the need for both precision and stability. This paper presents a novel intelligent control architecture that integrates a stable-by-design Passivity-Based Control (PBC) law with a bio-inspired reinforcement learning tuner. The core novelty lies in our Human Learning Behaviour (HLB) model, which, unlike conventional reward shaping, employs a finite-state machine to dynamically modulate the exploration strategy of a Deep Deterministic Policy Gradient (DDPG) agent. This state machine transitions between discrete states, framed as artificial emotions (e.g., Joy, Fear), based on real-time performance indicators. Each state directly adjusts the agent's exploration noise, enabling it to learn more efficiently by exploring aggressively when performance is poor and exploiting known good policies when performance is high. This adaptive tuner intelligently adjusts the proportional (Kp) and differential (KD) gains of the PBC law, which is derived from a Port-Controlled Hamiltonian (PCH) model to ensure the underlying manipulator dynamics remain stable for any positive-definite gains selected by the learning agent. Validated on an 8-DOF manipulator in simulated, obstacle-rich agricultural scenarios, the HLB-driven controller demonstrated a 77–80% improvement in trajectory tracking and a 30.7% reduction in energy consumption compared to fixed-gain and standard DDPG baselines, while maintaining a final tracking error of approximately 10⁻⁴ radians. The results confirm that our FSM-based adaptive exploration strategy yields a highly precise, energy-efficient, and robust intelligent control system suitable for complex robotic applications.",

      "abstract": "Spacecraft formation flying for interferometric observations around the 2nd Lagrange point in the Sun-Earth system (SEL2) is currently focal point in deep space exploration research, which demands high precision in relative position control of spacecraft. This paper proposes the relative motion dynamics of satellite formations around the L2 point in the port-Hamiltonian framework, and establishes a high-precision nonlinear dynamics model. PID passivity-based control (PID-PBC) is widely used in engineering. However, existing methods of PID-PBC cannot address the trajectory tracking issues in port-Hamiltonian systems. Utilizing the contraction properties of the port-Hamiltonian system, this paper proposes the trajectory tracking PID-PBC (tPID-PBC) approach, effectively resolving trajectory tracking issues for formation dynamics around L2 point in port-Hamiltonian framework. The paper details explicit solutions of the Partial Differential Equations (PDE) for the tPID-PBC method and its controller structure, and references the trajectories of interferometric observation formations, to verify the method’s effectiveness through numerical simulation. The presented control approach is applicable across generic port-Hamiltonian systems, offering substantial theoretical value.",

      "abstract": "To control the relative position and relative velocity of spacecraft formation, a time-varying nonlinear relative motion model under J 2 perturbation in an elliptical orbit is established in the port-Hamiltonian (PH) framework, and a distributed control law for spacecraft formation is developed using the consensus algorithm for parameter estimation and the passivity-based control (PBC) method based on the state-error interconnection and damping assignment (IDA) technique. First, the influence of J 2 perturbation on the potential energy and orbit parameters in the model is considered when the relative motion model is built in the PH frame, and the expression of the relative motion acceleration under J 2 perturbation is given. Second, to solve the problem that the state of the chief spacecraft cannot be directly obtained from the deputy spacecraft under distributed communication, a consensus-based parameter estimation method is introduced, the estimated parameter of the chief spacecraft is applied to the relative motion model in the PH frame, and a state error model with the estimated parameters derived from the consistency algorithm is established. Then, after the stability analysis is conducted on the desired PH system containing the estimated parameter values, the desired Hamiltonian energy function with the estimated parameters is designed according to the time-varying errors of the relative equilibrium states of the deputy spacecraft and the errors between deputy spacecraft, and the distributed control law of spacecraft formation is derived based on the state-error IDA-PBC method. Finally, the expected relative motion trajectory designed based on the TH equation is used to simulate a spacecraft formation under J 2 perturbation, and the results indicate that the spacecraft can quickly converge to the expected formation under the influence of the control law.",

      "abstract": "Due to the diverse shapes and weak irregular gravity of small bodies, conventional landers will encounter landing bounce. To solve this problem, this paper studies a recently proposed multi-node flexible lander, in order to elucidate the bounce suppression mechanism of the lander. Initially, the dynamic model of the lander is constructed based on the port-Hamiltonian system. A continuous contact model is employed to capture the dynamics of the collision interaction between the lander and the small body’s surface. Secondly, based on the dynamics model above, an energy-based analysis is conducted to compare the landing impact dissipation mechanism between conventional landers and the multi-node flexible lander. It is demonstrated that the multiple nodes and flexible connections configuration effectively attenuates landing impact, thereby suppressing bounce. Thirdly, the active control scheme for the multi-node flexible lander bounce suppression is proposed, which can further suppress the bounce. Finally, through comparative simulation experiments, the simulation results show that the bounce height of the multi-node flexible lander is obviously lower than that of the traditional lander, and the bounce height and bounce time will be further improved after the active control is applied. Monte Carlo landing experiments under various initial conditions are performed, further validating the efficacy of the multi-node flexible landing system in bounce suppression.",

      "abstract": "This paper proposes a nonlinear formation tracking control method using generalized canonical transformations with an adaptive mechanism for atmospheric drag. This method theoretically guarantees that satellites asymptotically track given reference trajectories in formation flying under disturbances, including atmospheric drag and the gravitational J2 effect. First, the nonlinear relative orbital motion is modeled in a port-Hamiltonian system. Second, a specific transformation is constructed for any twice differentiable reference formation trajectory that converts the system into an error system in the form of a time-varying passive port-Hamiltonian system based on generalized canonical transformations. Third, a passivity-based asymptotic stabilizing controller and an adaptive mechanism for the error system are presented, provided that the atmospheric drag coefficient is an unknown constant. Overall, the proposed method guarantees that the estimation error of the atmospheric drag coefficient is bounded and that the tracking error for the reference trajectory converges uniformly asymptotically to zero.",

      "abstract": "An energetic representation of helicopter flight controls, viewed as an Operator Assisting System, is proposed within the Port-Hamiltonian framework. The assisting controller modifies the dynamical behavior between the pilot stick and the swashplate, linked through a Continuous Variable Transmission, by enforcing force scaling and providing appropriate force feedback to the operator. Generic sufficient conditions are given on the assistance location and structure which allow the assisted system to be dissipative, hence providing nice stability and power scaling properties. Results are applied to the design of an assistance for a simplified flight control system. Simulations show the relevance of the method and are compared to real-life results.",

      "abstract": "Trajectory tracking control is pivotal for achieving autonomous operation in hydraulic excavators. This paper proposes a robust control scheme, merging passivity-based and impedance control, enhancing robustness and stability. First, the excavator’s coupled nonlinear dynamics are transformed into an open-loop port Hamiltonian model with disturbances. Through an energy shaping method, this model becomes an ideal closed-loop port Hamiltonian system, stabilized asymptotically by damping injection. An improved robust disturbance observer estimates system disturbances, guiding control compensation term design. Hydraulic cylinder forces and displacements are calculated from the closed-loop port Hamiltonian system’s matching equations. By integrating passivity and impedance control, a flow controller resolves electrohydraulic servo system nonlinearity. Comparative analysis with existing methodologies demonstrates the proposed robust controller’s superior tracking accuracy, even in the presence of shock disturbances.",

      "abstract": "This paper addresses trajectory tracking control of port-controlled Hamiltonian systems via generalized canonical transformations and passivity-based control. The main strategy adopted in this paper is to construct an error system, which describes the dynamics of the tracking error, by a passive port-controlled Hamiltonian system. After obtaining the error system, tracking control of the original system can be achieved by stabilizing the error system via passivity-based approach. First, a fundamental framework is provided for constructing the error system via generalized canonical transformations. Then a concrete design procedure is derived for a class of electro-mechanical systems. Furthermore, the proposed method is applied to a magnetic levitation system and laboratory experiments demonstrate its effectiveness.",

      "abstract": "A fundamental problem in the simulation and control of complex physical systems containing distributed-parameter components concerns finite-dimensional approximation. Numerical methods for partial differential equations (PDEs) usually assume the boundary conditions to be given, while more often than not the interaction of the distributed-parameter components with the other components takes place precisely via the boundary. On the other hand, finite-dimensional approximation methods for infinite-dimensional input–output systems (e.g., in semi-group format) are not easily relatable to numerical techniques for solving PDEs, and are mainly confined to linear PDEs. In this paper we take a new view on this problem by proposing a method for spatial discretization of boundary control systems based on a particular type of mixed finite elements, resulting in a finite-dimensional input–output system. The approach is based on formulating the distributed-parameter component as an infinite-dimensional port-Hamiltonian system, and exploiting the geometric structure of this representation for the choice of appropriate mixed finite elements. The spatially discretized system is again a port-Hamiltonian system, which can be treated as an approximating lumped-parameter physical system of the same type. In the current paper this program is carried out for the case of an ideal transmission line described by the telegrapher's equations, and for the two-dimensional wave equation.",

For physical systems a natural candidate storage function is the difference between the stored and the supplied energies—leading to the so-called energy-balancing control, whose underlying stabilization mechanism is particularly appealing. Unfortunately, energy-balancing stabilization is stymied by the existence of pervasive dissipation, that appears in many engineering applications. To overcome the dissipation obstacle the method of Interconnection and Damping Assignment, that endows the closed-loop system with a special—port-controlled Hamiltonian—structure, has been proposed. If, as in most practical examples, the open-loop system already has this structure, and the damping is not pervasive, both methods are equivalent. In this brief note we show that the methods are also equivalent, with an alternative definition of the supplied energy, when the damping is pervasive. Instrumental for our developments is the observation that, swapping the damping terms in the classical dissipation inequality, we can establish passivity of port-controlled Hamiltonian systems with respect to some new external variables—but with the same storage function.",

The paper investigates the two basic problems. A suitable geometric structure for time-varying PCH systems is proposed first. Then the dissipative realization problem of time-varying nonlinear systems is investigated, and serval new methods and sufficient conditions are presented for the realization.",

The key to make good use of the SMES units is to design effective controllers. This paper presents a number of results on the analysis and control of multi-machine power systems with such units via Hamiltonian function method. It has been shown that the multi-machine power systems with SMES units can be made to be a port-controlled Hamiltonian (PCH) system by using a state feedback control, and that the stability of the resulting system can be established. Furthermore, this paper proposes a novel energy-based adaptive L 2 disturbance attenuation control scheme for the multi-machine systems with SMES units. The control scheme is a decentralized one and consists of two parts: one is an L 2 disturbance attenuation excitation controller for the generators, and the other is an adaptive L 2 disturbance attenuation controller for the SMES units. Simulations on a six-machine system with one SMES unit show that the proposed control scheme is very effective.",

      "abstract": "Port-based network modeling of physical systems leads to a model class of nonlinear systems known as port-Hamiltonian systems. Port-Hamiltonian systems are defined with respect to a geometric structure on the state space, called a Dirac structure. Interconnection of port-Hamiltonian systems results in another port-Hamiltonian system with Dirac structure defined by the composition of the Dirac structures of the subsystems. In this paper the composition of Dirac structures is being studied, both in power variables and in wave variables (scattering) representation. This latter case is shown to correspond to the Redheffer star product of unitary mappings. An equational representation of the composed Dirac structure is derived. Furthermore, the regularity of the composition is being studied. Necessary and sufficient conditions are given for the achievability of a Dirac structure arising from the standard feedback interconnection of a plant port-Hamiltonian system and a controller port-Hamiltonian system, and an explicit description of the class of achievable Casimir functions is derived.",

      "abstract": "This paper investigates simultaneous stabilization of a set of nonlinear port-controlled Hamiltonian (PCH) systems and proposes a number of results on the design of simultaneous stabilization controllers for the PCH systems. Firstly, the case of two PCH systems is studied. Using the dissipative Hamiltonian structural properties, the two systems are combined to generate an augmented PCH system, with which some results on the control design are then obtained. For the case that there exist parametric uncertainties in the two systems’ Hamiltonian structures, an adaptive simultaneous stabilization controller is proposed. When there are external disturbances and parametric uncertainties in the two systems, two simultaneous stabilization controllers are designed for the systems: one is a robust controller and the other is a robust adaptive one. Secondly, the case of more than two PCH systems is investigated, and a new result is proposed for the simultaneous stabilization of the systems. Finally, two illustrative examples are studied by using the results proposed in this paper. Simulations show that the simultaneous stabilization controllers obtained in this paper work very well.",

A non-minimal kernel representation of this family of structures (named Dirac structures) is presented. It is derived from the parameterized incidence matrices which are a mathematical representation of the primal and dual dynamic network graphs associated with the system. This representation has the advantage of making it possible to model complex physical switching systems with varying constraints and to fall within the framework of passivity-based control.",

The control design is focused on the presentation of a new energy-shaping methodology for tracking control based on the introduction of virtual non-homogeneous fields where a desired energy is defined to compensate for the actual energy of the robot manipulator while a virtual field forces the system to track a general reference trajectory. This requires use of the Legendre–Fenchel transformation and allows for the derivation standard control laws in the robotics field such as PD control with gravity compensation or PD with precompensation. Finally, the passivity of the input–output mapping of the non-autonomous Hamiltonian system is analyzed in detail, resulting in new Lyapunov candidate functions having their roots in physics.",

It is well-known that the method, in its basic form, imposes some unnatural controller initialization to yield asymptotic stability of the desired equilibrium. We propose two different ways to overcome this restriction, one based on adaptation ideas, and the other one adding an extra damping injection to the controller. The analysis and design principles are illustrated through an academic example.",

      "abstract": "A technique that provides closed loop integral action depending on the passive outputs of port-controlled Hamiltonian systems is already available. This paper addresses a new method that allows us to add integral action also on system variables having relative degree higher than one, while still preserving the Hamiltonian form and, thus, closed loop stability. The new approach is applied to design speed regulation controllers for the permanent magnet synchronous motor. Closed loop stability and asymptotic rejection of unknown piecewise constant load torques are formally proved. This theoretically predicted control system performance is illustrated via simulation experiments, which also show that the properties hold under parameter uncertainties. This is in line with the usual practice of including integral action in a controller with the aim of improving its closed loop robustness. The fact that the method enhances the range of possible integral actions in the controller, enriched with this robustness property, allows us to assess it as a practically important complement to the well-known interconnection and damping assignment techniques developed in the framework of port-controlled Hamiltonian systems.",

It is shown how to employ the Arnoldi method for model reduction in a particular coordinate system in order to preserve not only a specific number of the Markov parameters but also the port-Hamiltonian structure for the reduced order model. Furthermore it is shown how the Lanczos method can be applied in a structure preserving manner to a subclass of port-Hamiltonian systems which is characterized by an algebraic condition. In fact, for the same subclass of port-Hamiltonian systems the Arnoldi method and the Lanczos method turn out to be equivalent in the sense of producing reduced order port-Hamiltonian models with the same transfer function.",

The essential idea is to make the augmented system consisting of the plant and the observer dynamics to become strictly passive with respect to an invariant manifold defined on the extended state-space, on which the state estimation error is zero. We first introduce the concept of passivity of a system with respect to a manifold by defining a new input and output on the extended state-space and then perform a partial state feedback passivation which leads to the construction of the observer. We then illustrate this observer design procedure on two physical examples, the magnetic levitation system and the inverted pendulum on the cart system.",

First, the stabilization problem is studied, and a control design method is developed by using both the dissipative Hamiltonian structural and saturating actuator properties. Second, for the case that there are external disturbances in the systems, an H ∞ controller is designed to attenuate the disturbances. Finally, the results obtained for Hamiltonian systems are applied to the stabilization and H ∞ control of nonlinear affine systems subject to actuator saturation, and several interesting results are presented. Study of an example of power system with simulations shows that the controller proposed in this paper is effective.",

      "abstract": "This contribution is concerned with self-sensing actuation (SSA) for the adaptive vibration control of smart structures with piezoelectric actuators. The electro-mechanical model of a Kirchhoff plate equipped with two piezoelectric patches is rewritten in the form of an infinite dimensional port controlled Hamiltonian system with dissipation (PCHD) where collocation of input and output is achieved by SSA. In the case of piezoelectric actuators, self sensing requires a robust separation of electric current due to the direct piezoelectric effect from the measured electric current. Because of the unfavorable ratio of these two signals, the design of an approximate observer for the electric current due to the direct piezoelectric effect is proposed. The control design goal is the asymptotic suppression of a harmonic disturbance with unknown frequency, amplitude and phase. The control law is derived for the plant augmented by an appropriate exosystem, which models the properties of the disturbance. The novelty of this contribution is the extension of the control design methods from the finite dimensional case to the infinite dimensional one. The stability analysis for the infinite dimensional system is based on the concept of L 2 -stability and the small gain theorem. Vibration attenuation around a dominant eigenfrequency is demonstrated by simulation and experiment.",

      "abstract": "This contribution presents two approximation methods for linear infinite-dimensional systems that ensure the preservation of stability and passivity. The first approach allows one to approximate internal source free infinite-dimensional systems such that the resulting approximation is a port-controlled Hamiltonian system with dissipation. The second method deals with the class of systems that are not required to have conjugated outputs but only a dissipative system operator. It yields approximations with a dissipative system matrix for which bounds of their stability margin are provided. Both approaches are based on a state space formulation of the infinite-dimensional system. This makes it possible to use the Petrov–Galerkin approximation whose free parameters are partly used for achieving the structure preservation. Since still free parameters remain, further application specific objectives, such as, e.g., moment matching, can be achieved. Both approaches are applied to the approximation of an Euler–Bernoulli beam.",

In this paper, we develop a framework for model reduction of large-scale multi-input/multi-output port-Hamiltonian systems via tangential rational interpolation. The resulting reduced model is a rational (tangential) interpolant that retains the port-Hamiltonian structure; hence it remains passive. We introduce an H 2 -inspired algorithm for effective choice of interpolation points and tangent directions and present several numerical examples illustrating its effectiveness.",

This formulation is based on the splitting of the state bundle and the use of appropriate covariant derivatives, which guarantees that the structure of the equations is invariant with respect to time-variant coordinate transformations. In particular, we will interpret our covariant system representation in the context of control theoretic problems. Typical examples are time-variant error systems related to trajectory tracking problems which allow for a Hamiltonian formulation. Furthermore we will analyze the concept of collocation and the balancing/interaction of power flows in an intrinsic fashion.",

First we study canonical forms for port-Hamiltonian systems with nonholonomic constraints.

Third, we propose a dynamic output feedback stabilization method without measuring the velocity based on the corresponding state feedback result. Numerical examples demonstrate the effectiveness of the proposed method.",

      "abstract": "This paper investigates the finite-time stability (FTS) analysis and finite-time H ∞ control design for a class of nonlinear time-delay Hamiltonian systems, and proposes some delay-dependent results on both the FTS and finite-time control design. First, a criterion on the FTS is proposed for general time-delay nonlinear systems via the Razumikhin approach. Then, based on the criterion, some delay-independent and delay-dependent conditions on the FTS are derived for the nonlinear time-delay Hamiltonian systems by constructing a suitable Lyapunov function. Third, we use the obtained FTS results to investigate the finite-time H ∞ control problem, and present a control design procedure for a class of nonlinear time-delay port-controlled Hamiltonian systems by the energy-shaping approach. Study of two illustrative examples shows that the results obtained in this paper work very well in the FTS analysis and control design of some nonlinear time-delay Hamiltonian systems.",

      "abstract": "In this paper, the technique of local linear dynamics assignment is presented, which complements the powerful Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) methodology. In IDA-PBC, nonlinear state feedback controllers are designed by matching the system’s dynamics with a desired Port-Hamiltonian (PH) state representation. The latter consists of an energy function, which serves as the closed-loop Lyapunov function, as well as matrices, describing the virtual internal exchange and dissipation of the energy. A major difficulty in IDA-PBC is how to determine reasonable values for the large number of free design parameters. Local linear dynamics assignment offers a solution to this problem with a number of advantages. (i) Invoking the closed-loop Jacobian linearization to fix the parameter values provides transparency with respect to the resulting local dynamic behavior. (ii) An appropriate state transformation isolates the coordinates available for energy shaping. (iii) A related local linear state transformation makes the resulting system of design equations linear. (iv) Assigning a Hurwitz closed-loop Jacobian and ensuring positive semi-definiteness of the closed-loop dissipation matrix, the tedious definiteness check of the energy is omitted. The design steps are illustrated with the Ball on Wheel example.",

The Immersion & Invariance methodology is adopted, with the main result formulated in the Port-Hamiltonian framework, for both model and target dynamics. The procedure is applicable to mechanical systems with under-actuation degree larger than one, extending the results recently reported by some of the authors. The approach is successfully applied to two benchmark examples and some basic connections with the interconnection and damping assignment passivity-based control are revealed. An additional contribution of this work is the identification of a class of mechanical systems whose mechanical structure remains invariant under partial feedback linearization.",

We characterize several families of parameterized port Hamiltonian models that match the moments of a given port Hamiltonian system, at a set of finite interpolation points. We also discuss the problem of Markov parameters matching for linear systems as a moment matching problem for descriptor representations associated with the given system, at zero interpolation points. Solving this problem yields families of parameterized reduced order models that achieve Markov parameter matching. Finally, we apply these results to the port Hamiltonian case, resulting in families of parameterized reduced order port Hamiltonian approximations.",

These finite-dimensional Dirac structures offer a framework for the formulation of standard input–output finite-dimensional port-Hamiltonian systems that emulate the behavior of distributed-parameter port-Hamiltonian systems. This paper elaborates on the matrix representations of simplicial Dirac structures and the resulting port-Hamiltonian systems on simplicial manifolds. Employing these representations, we consider the existence of structural invariants and demonstrate how they pertain to the energy shaping of port-Hamiltonian systems on simplicial manifolds.",

      "abstract": "Inspired by the recent developments in modeling and analysis of reaction networks, we provide a geometric formulation of the reversible reaction networks under the influence of diffusion. Using the graph knowledge of the underlying reaction network, the obtained reaction–diffusion system is a distributed-parameter port-Hamiltonian system on a compact spatial domain. Motivated by the need for computer-based design, we offer a spatially consistent discretization of the PDE system and, in a systematic manner, recover a compartmental ODE model on a simplicial triangulation of the spatial domain. Exploring the properties of a balanced weighted Laplacian matrix of the reaction network and the Laplacian of the simplicial complex, we characterize the space of equilibrium points and provide a simple stability analysis on the state space modulo the space of equilibrium points. The paper rules out the possibility of the persistence of spatial patterns for the compartmental balanced reaction–diffusion networks.",

      "abstract": "We consider the problem of stability analysis for droop-controlled inverter-based microgrids with meshed topologies. The inverter models include variable frequencies as well as voltage amplitudes. Conditions on the tuning gains and setpoints for frequency and voltage stability, together with desired active power sharing, are derived in the paper. First, we prove that for all practical choices of these parameters global boundedness of trajectories is ensured. Subsequently, assuming the microgrid is lossless, a port-Hamiltonian description is derived, from which sufficient conditions for stability are given. Finally, we propose for generic lossy microgrids a design criterion for the controller gains and setpoints such that a desired steady-state active power distribution is achieved. The analysis is validated via simulation on a microgrid based on the CIGRE (Conseil International des Grands Réseaux Electriques) benchmark medium voltage distribution network.",

The control goal is to make the constellation converge to a circular target orbit, while spatially distributing the satellites at equal inter-satellite distances. The solution is defined in the port-Hamiltonian framework, which gives a clear physical interpretation of the obtained control laws, insight into the energy consumption and complete stability proofs. The controller consists of two parts: the internal control system steers each individual satellite to the target orbit, the external control system equally distributes the satellite constellation. Numerical simulation results are given to illustrate the effectiveness of the approach.",

      "abstract": "Irreversible port-Hamiltonian systems (IPHS) have recently been proposed for the modelling of irreversible thermodynamic systems. On the other hand, a classical result on the use of the second law of thermodynamics for the stabilization of irreversible processes is the celebrated thermodynamic availability function. These frameworks are combined to propose a class of Passivity Based Controller (PBC) for irreversible processes. An alternative formulation of the availability function in terms of internal energy is proposed. Using IPHS a matching-condition, which is interpreted in terms of energy-shaping, is derived and a specific solution that permits to assign a desired closed-loop structure and entropy rate is proposed. The approach can be compared with Interconnection and Damping Assignment-PBC, this method however leads in general to thermodynamically non-coherent closed-loop systems. In this paper a system theoretic approach is employed to derive a constructive method for the control design. The closed-loop system is in IPHS form, hence it can be identified with a thermodynamic system and the control parameters related with thermodynamic variables, such as the reaction rates in the case of chemical reactions. A generic non-linear non-isothermal continuous stirred tank reactor is used to illustrate the approach.",

      "abstract": "The presence of dissipation hampers our ability to shape the energy of port-Hamiltonian systems using control-by-interconnection methods—a phenomenon called the dissipation obstacle. In particular, the Casimir functions that are used to shift the energy function cannot depend on the coordinates where dissipation is present if we use passive controllers. Recently, it was proposed to relax the latter condition using non-passive controllers that inject energy into the system to be able to create the required Casimir functions. In this note we prove that, alas, even if the Casimirs can be created with active controllers the dissipation obstacle stymies the possibility to assign an energy function with the minimum at an equilibrium point. As a corollary we prove that the deleterious effect of pervasive dissipation does not only stem from the inability of the controller to inject the (infinite) energy required for stabilization—as it was stated in earlier publications.",

A dynamical model including the planar discontinuous friction force is presented in the port-Hamiltonian framework. Moreover, continuous and discontinuous controllers are designed in order to achieve a desired prescribed formation. The main results are derived using tools from nonsmooth Lyapunov analysis. It is shown that the continuous static feedback controller fails to achieve the exact formation, while the discontinuous controller achieves the desired task exactly. Numerical simulations are provided to illustrate the effectiveness of the approach.",

The upper bounds for the deviations in networks of first or second order agents, respectively, depend on the minimal eigenvalue of the extended Laplacian of the system. In networks of first order agents, the deviations decay exponentially with a rate depending on the same minimal eigenvalue. In case networks of second order systems meet specific design properties, it can be shown that the deviations also decay exponentially with half the rate compared to first order systems.",

      "abstract": "Equilibrium stabilization of nonlinear systems via energy shaping is a well-established, robust, passivity-based controller design technique. Unfortunately, its application is often stymied by the need to solve partial differential equations, which is usually a difficult task. In this paper a new, fully constructive, procedure to shape the energy for a class of port-Hamiltonian systems that obviates the solution of partial differential equations is proposed. Proceeding from the well-known passive, power shaping output we propose a nonlinear static state-feedback that preserves passivity of this output but with a new storage function. A suitable selection of a controller gain makes this function positive definite, hence it is a suitable Lyapunov function for the closed-loop. The resulting controller may be interpreted as a classical PI—connections with other standard passivity-based controllers are also identified.",

The control and disturbance signals entering the nodal dynamics are “unmatched” meaning that some nodes are only subject to disturbances and not to the actuating signals. To further enrich our model and motivated by synchronization problems in physical networks, we accommodate (solvable) algebraic constraints resulting in a fairly general and heterogeneous network. It is shown that appropriate dynamic feedback controllers achieve output agreement on a desired vector, in the presence of physical coupling and despite the influence of constant as well as time-varying disturbances. Furthermore, we address the case of an optimal steady-state deployment of the control effort over the network by suitable distributed controllers. As a case study, the proposed results are applied to a heterogeneous microgrid.",

      "abstract": "This paper considers a string of vehicles where the local control law uses the states of the vehicle’s immediate predecessor and follower. The coupling towards the preceding vehicle can be chosen different to the coupling with the following vehicle, which is referred to as an asymmetric bidirectional string. Further, the asymmetry for the velocity coupling can be chosen differently to the asymmetry in the position coupling. It is investigated how the effect of the disturbance on the control errors in the string depends on the string length. It is shown, that in case of symmetric position coupling and asymmetric velocity coupling, linear scaling can be achieved. For symmetric interactions, the errors scale quadratically in the number of vehicles. When the coupling in position is asymmetric, exponential scaling may occur or the system might even become unstable. The paper thus gives a comprehensive overview of the achievable performance in linear, asymmetric, bidirectional platoons. The results reveal that symmetry in the position coupling and asymmetry in velocity coupling qualitatively improve the performance of the string. Extensive numerical results illustrate the theoretical findings.",

      "abstract": "The conditions for existence of solutions and stability, asymptotic and exponential, of a large class of boundary controlled systems on a 1D spatial domain subject to nonlinear dynamic boundary actuation are given. The consideration of such class of control systems is motivated by the use of actuators and sensors with nonlinear behavior in many engineering applications. These nonlinearities are usually associated to large deformations or the use of smart materials such as piezo actuators and memory shape alloys. Including them in the controller model results in passive dynamic controllers with nonlinear potential energy function and/or nonlinear damping forces. First it is shown that under very natural assumptions the solutions of the partial differential equation with the nonlinear dynamic boundary conditions exist globally. Secondly, when energy dissipation is present in the controller, then it globally asymptotically stabilizes the partial differential equation. Finally, it is shown that assuming some additional conditions on the interconnection and on the passivity properties of the controller (consistent with physical applications) global exponential stability of the closed-loop system is achieved.",

We propose new algorithms to solve this problem based on a reformulation using linear dissipative Hamiltonian systems: we show that a matrix A is stable if and only if it can be written as A = ( J − R ) Q , where J = − J T , R ⪰ 0 and Q ≻ 0 (that is, R is positive semidefinite and Q is positive definite). This reformulation results in an equivalent optimization problem with a simple convex feasible set. We propose three strategies to solve the problem in variables ( J , R , Q ) : (i) a block coordinate descent method, (ii) a projected gradient descent method, and (iii) a fast gradient method inspired from smooth convex optimization. These methods require O ( n 3 ) operations per iteration, where n is the size of A . We show the effectiveness of the fast gradient method compared to the other approaches and to several state-of-the-art algorithms.",

We define a synchronous steady-state behavior which corresponds to the desired nominal operating point of a power system and obtain necessary and sufficient conditions on the control inputs, load model, and transmission network, under which the power system admits this steady-state behavior. We arrive at a separation between the steady-state conditions of the transmission network and generators, which allows us to recover the steady-state of the entire power system solely from a prescribed operating point of the transmission network. Moreover, we constructively obtain necessary and sufficient steady-state conditions based on network balance equations typically encountered in power flow analysis. Our analysis results in several necessary conditions that any power system control strategy needs to satisfy.",

      "abstract": "In this paper, we describe the development of a Riemannian optimal model reduction method for linear stable port-Hamiltonian systems. This development is motivated by the fact that there remains room for improvement in existing methods. The model reduction problem is formulated as an optimization problem on the product manifold of the set of skew symmetric matrices, the manifold of the symmetric positive definite matrices, and Euclidean space. The reduced systems constructed using the optimal solutions to the problem preserve the original structure, i.e., stability, passivity, and the port-Hamiltonian form. The Riemannian gradient is derived to relate our problem to another problem in some studies, and the Hessian is also derived to solve our problem using a Riemannian trust region method. The initial point in the proposed method is chosen by using the output of the iterative rational Krylov algorithm for linear port-Hamiltonian systems (IRKA-PH). A numerical experiment illustrates that the proposed method considerably improves the results of IRKA-PH when the reduced-model dimension is small.",

To this end, a structure preserving reduction method and a modified LQG control design are combined to derive a reduced order model suitable for control purposes. We first recall the structure preserving reduction method for port Hamiltonian systems called effort constraint method and characterize the error bound associated to this reduction method. We then give sufficient conditions for non-standard LQG design which allow to design a passive controller equivalent to the control by interconnection of port Hamiltonian systems. This LQG method allows to define an LQG balanced realization by computing the LQG Gramians, the effort-constraint method is then used to derive a reduced order port Hamiltonian system and to design a reduced order passive LQG controller. Finally, the method is illustrated in simulation on a mass–spring–damper system. The performances of the reduced order controller are compared to the results obtained with a full order passive LQG controller.",

      "abstract": "The main contribution of this paper is a general synthesis methodology of exponentially stabilising control laws for a class of boundary control systems in port-Hamiltonian form that are dissipative with respect to a quadratic supply rate, being the total energy the storage function. More precisely, general conditions that a linear regulator has to satisfy to have, at first, a well-posed and, secondly, an exponentially stable closed-loop system are presented. The methodology is illustrated with reference to two specific stabilisation scenarios, namely when the (distributed parameter) plant is in impedance or in scattering form. Moreover, it is also shown how these techniques can be employed in the analysis of more general systems that are described by coupled partial and ordinary differential equations. In particular, the repetitive control scheme is studied, and conditions on the (finite dimensional) linear plant to have asymptotic tracking of generic periodic reference signals are determined.",

In particular, we obtain constructive sufficient conditions for stochastic feedback stabilization that provide a shaped energy function for the closed-loop system while preserving a Hamiltonian structure at the closed-loop level. In the dynamic control case, energy shaping is achieved by combining the physical energy of the plant and the emulated energy of the controller. Several numerical examples are presented that demonstrate the efficacy of the proposed passivity-based stochastic control framework.",

Such representations are typically not unique and the degrees of freedom associated with nonuniqueness are related to the solution set of the Kalman–Yakubovich–Popov linear matrix inequality (LMI). In this paper we analyze robustness measures for different possible port-Hamiltonian representations and relate it to quality functions defined in terms of eigenvalues of the matrix solution of the LMI. In particular, we look at the analytic center of this LMI. Within this framework, we derive inequalities for the passivity radius of the given model representation.",

      "abstract": "The zero dynamics of infinite-dimensional systems can be difficult to characterize. The zero dynamics of boundary control systems are particularly problematic. In this paper the zero dynamics of port-Hamiltonian systems are studied. A complete characterization of the zero dynamics for port-Hamiltonian systems with invertible feedthrough as another port-Hamiltonian system on the same state space is given. It is shown that the zero dynamics for any port-Hamiltonian system with commensurate wave speeds are a well-posed system, and are also a port-Hamiltonian system. Examples include wave equations with uniform wave speed on a network. A constructive procedure for calculation of the zero dynamics that can be used for very large system order is provided.",

The velocity of the desired trajectory and parts of the model information are unknown apart from boundedness assumptions. A velocity observer based method and a sliding mode controller are proposed while the asymptotic tracking result is guaranteed by a zero-state detectability condition for both cases. Unlike previous results, the studied systems are not necessarily feedback linearizable nor in a strict feedback form. The ball and beam system is utilized to illustrate the implementation of the proposed tracking control laws.",

A suitable framework is provided to model these systems and to investigate their shifted passivity properties, based on which a stability analysis is carried out. The applicability of the results is illustrated with the important problem of stability analysis of electrical circuits with constant power loads.",

Here, mathematical model for hyperthermia therapy involves solution to the thermal wave equation as state while the control is given by the pointwise time dependent heat source. The target is the temperature at a given point within the tumor. Pointwise optimal control problem on and inside a tissue is solved subject to thermal wave model with Dirichlet and Rubin boundary conditions. The pointwise heating source induced by heating probe inserted at the tumor site as control at specific depth inside the biological body. Solutions for both thermal wave problem and its associated adjoint problem are proposed. Approximate controllability of the thermal wave problem is derived with the help of strongly continuous semigroups theory. We prove that the system is pseudo-port Hamiltonian. Pointwise time dependent optimal control problem is solved by using time discretization, conjugate gradient technique and strongly continuous semigroups theory. A set of numerical experiments concerning the design of optimal heating power strategy in cancer treatment by hyperthermia are presented.",

      "abstract": "Port-Hamiltonian system theory is a well-known framework for the control of complex physical systems. The majority of port-Hamiltonian control design methods base on an explicit input-state-output port-Hamiltonian model for the system under consideration. However in the literature, little effort has been made towards a systematic, automatable derivation of such explicit models. In this paper, we present a constructive, formally rigorous method for an explicit port-Hamiltonian formulation of multi-bond graphs. Two conditions, one necessary and one sufficient, for the existence of an explicit port-Hamiltonian formulation of a multi-bond graph are given. We summarise our approach in an algorithm for the automated generation of an explicit port-Hamiltonian model from a given multi-bond graph. An academic example illustrates the results of this paper.",

      "abstract": "An observer-based boundary controller for infinite-dimensional port-Hamiltonian systems defined on 1D spatial domains is proposed. The design is based on an early-lumping approach in which a finite-dimensional approximation of the infinite-dimensional system derived by spatial discretization is used to design the observer and the controller. As long as the finite-dimensional approximation approaches the infinite-dimensional model, the performances also do. The main contribution is a constructive method which guarantees that the interconnection between the controller and the infinite-dimensional system is asymptotically stable. A Timoshenko beam model has been used to illustrate the approach.",

      "abstract": "In this paper, we propose a continuous-time adaptive feedback controller for the optimal control of input-state-output port-Hamiltonian systems with respect to general Lagrangian performance indices. The proposed control law implements an online learning procedure which uses the Hamiltonian of the system as an initial value function candidate. The continuous-time learning of the value function is achieved by means of a certain Lagrange multiplier that allows to evaluate the optimality of the current solution. In particular, constructive conditions for stabilizing initial value function candidates are stated and asymptotic stability of the closed-loop equilibrium is proven. Simulations of an exemplary nonlinear optimal control problem demonstrate the performance of the controller resulting from the proposed online learning procedure.",

      "abstract": "We present a novel approach for discrete-time state feedback control implementation which reduces the deteriorating effects of sampling on stability and performance in digitally controlled nonlinear mechanical systems. We translate the argument of energy shaping to discrete time by using the symplectic implicit midpoint rule. The method is motivated by recent results for linear systems, where feedback imposes closed-loop behavior that exactly represents the symplectic discretization of a desired target system. For the nonlinear case, the sampled system and the target dynamics are approximated with second order accuracy using the implicit midpoint rule. The implicit nature of the resulting state feedback requires the numerical solution of an in general nonlinear system of algebraic equations in every sampling interval. For an implementation with pure position feedback, the velocities/momenta have to be approximated in the sampling instants, which gives a clear interpretation of our approach in terms of the Störmer–Verlet integration scheme on a staggered grid. Both the Hamiltonian and the Lagrangian perspective are adopted. We present discrete-time versions of impedance or energy shaping plus damping injection control as well as computed torque tracking control in the simulation examples to illustrate the performance and stability gain compared to the quasi-continuous implementation. We discuss computational aspects and show the structural advantages of the implicit midpoint rule compared to other integration schemes in the appendix.",

We introduce a suitable definition of discrete SPHS based on symplectic variational integrators. By properly choosing the collocation points for discrete-time SPHS we are able to approximate a continuous SPHS. Moreover, under suitable assumptions on the Hamiltonian of the system, we guarantee energy conservation, which is a key property in the standard PHS framework. Numerical examples are provided to show the goodness of the proposed method.",

The proposed solution is based on the virtual contractivity-based control (v-CBC) method, which employs the notions of virtual systems and of contractivity. This approach leads to a family of asymptotic tracking controllers that are not limited to those that preserve the pH structure of the closed-loop system nor require an intermediate change of coordinates. Nevertheless, structure preservation and other properties (e.g., passivity) are possible under sufficient conditions. The performance of the proposed v-CBC scheme is experimentally evaluated on a planar robot of two degrees of freedom (DoF).",

      "abstract": "This paper deals with the asymptotic stabilization of a class of port-Hamiltonian (pH) 1-D Partial Differential Equations (PDE) with spatial varying parameters, interconnected with a class of linear Ordinary Differential Equations (ODE), with control input on the ODE. The class of considered ODE contains the effect of a proportional term, that can be considered as the proportional action of a controller or a spring in case of mechanical systems. In this particular case of study, it is not possible to directly add damping on the boundary of the PDE. To remedy this problem we propose a control law that makes use of a “strong feedback” term. We first prove that the closed-loop operator generates a contraction strongly continuous semigroup, then we address the asymptotic stability making use of a Lyapunov argument, taking advantage of the pH structure of the original system to be controlled. Furthermore, we apply the proposed control law for the stabilization of a vibrating string with a tip mass and we show the simulation results compared with the application of a simple PD controller.",

      "abstract": "We present a novel model-order reduction (MOR) method for linear time-invariant systems that preserves passivity and is thus suited for structure-preserving MOR for port-Hamiltonian (pH) systems. Our algorithm exploits the well-known spectral factorization of the Popov function by a solution of the Kalman–Yakubovich–Popov (KYP) inequality. It performs MOR directly on the spectral factor inheriting the original system’s sparsity enabling MOR in a large-scale context. Our analysis reveals that the spectral factorization corresponding to the minimal solution of an associated algebraic Riccati equation is preferable from a model reduction perspective and benefits pH-preserving MOR methods such as a modified version of the iterative rational Krylov algorithm (IRKA). Numerical examples demonstrate that our approach can produce high-fidelity reduced-order models close to (unstructured) H 2 -optimal reduced-order models.",

      "abstract": "Based on the port-Hamiltonian framework, this paper proposes a novel control scheme for stabilising the voltage in DC networks affected by (i) unknown ZIP-loads, i.e., nonlinear loads consisting of the parallel combination of constant impedance (Z), current (I) and power (P) load types, and (ii) unknown (but bounded) time-varying disturbances. Differently from the results existing in the literature, where restrictive (sufficient) conditions on the load parameters, voltage trajectory and voltage reference are assumed to be satisfied, this is the first paper (to the best of our knowledge) proposing a controller that relaxes such conditions and guarantees the exponential stability of the desired equilibrium point, whose region of attraction can be increased by simply tuning the control gains. In the case the network is affected by unknown time-varying disturbances, local input-to-state stability (l-ISS) is ensured. Furthermore, if non-ideal P-loads are considered, excluding the unrealistic possibility that the load absorbs infinite current when the voltage approaches zero, the aforementioned stability results hold globally.",

      "abstract": "We present a new fixed-order H-infinity controller design method for potentially large-scale port-Hamiltonian (pH) plants. Our method computes controllers that are also pH (and thus passive) such that the resulting closed-loop systems is again passive, which ensures closed-loop stability simply from the structure of the plant and controller matrices. In this way, we can avoid computationally expensive eigenvalue computations that would otherwise be necessary. In combination with a sample-based objective function which allows us to avoid multiple evaluations of the H-infinity norm (which is typically the main computational burden in fixed-order H-infinity controller synthesis), this makes our method well-suited for plants with a high state–space dimension. In our numerical experiments, we show that applying a passivity-enforcing post-processing step after using well-established H-infinity synthesis methods often leads to a deteriorated H-infinity performance. By contrast, our method computes pH controllers, that are automatically passive and simultaneously aim to minimize the H-infinity norm of the closed-loop transfer function. Moreover, our experiments show that for large-scale plants, our method is significantly faster than the well-established fixed-order H-infinity controller synthesis methods.",

      "abstract": "An in-domain finite dimensional controller for a class of distributed parameter systems on a one-dimensional spatial domain formulated under the port-Hamiltonian framework is presented. Based on (Trenchant et al. 2017) where positive feedback and a late lumping approach is used, we extend the Control by Interconnection method and propose a new energy shaping methodology with an early lumping approach on the distributed spatial domain of the system. Our two main control objectives are to stabilize the closed-loop system, as well as to improve the closed-loop dynamic performances. With the early lumping approach, we investigate two cases of the controller design, the ideal case where each distributed controller acts independently on the spatial domain (fully-actuated), and the more realistic case where the control action is piecewise constant over certain intervals (under-actuated). We then analyze the asymptotic stability of the closed-loop system when the infinite dimensional plant system is connected with the finite dimensional controller. Furthermore we provide simulation results comparing the performance of the fully-actuated case and the under-actuated case with an example of an elastic vibrating string.",

      "abstract": "This paper proposes an extended interconnection and damping assignment passivity-based control technique to control the pressure dynamics in the fuel delivery subsystem of proton exchange membrane fuel cells. The fuel cell stack is a distributed parameter model which can be modeled by partial differential equations. In this paper, the segmentation concept is used to approximate the partial differential equations model by ordinary differential equations model. Therefore, each segment is having multiple ordinary differential equations to obtain the lump-sum model of the segments. Subsequently, a generalized multi-input multi-output lumped parameters model is developed in port-Hamiltonian framework based on mass balance to minimize the modeling error. The modeling errors arise due to the difference between spatially distributed pressures in the segments, and also due to the difference between the actual stack pressure and the measured output pressure of the anode. The segments interconnection feasibility is ensured by maintaining passivity of each segment. With consideration of re-circulation and bleeding of the anode in the modeling, an extended energy-shaping and output tracking state-feedback controller is proposed to control the spatially distributed pressure dynamics in the anode. Furthermore, a sliding mode observer of high order is designed to estimate the unmeasurable pressures with known disturbances. Performance recovery of output feedback control is accomplished with explicit stability analysis. The effectiveness of the proposed control approach is validated by the simulation results.",

      "abstract": "The model reduction problem in the Loewner framework for port-Hamiltonian and network systems on graphs is studied. In particular, given a set of right-tangential interpolation data, the (subset of) left-tangential interpolation data that allow constructing an interpolant possessing a port-Hamiltonian structure is characterized. In addition, conditions under which an interpolant retains the underlying port-Hamiltonian structure of the system generating the data are given by requiring a particular structure of the generalized observability matrix. Ipso facto a characterization of the reduced order model in terms of Dirac structure with the aim of relating the Dirac structure of the underlying port-Hamiltonian system with the Dirac structure of the constructed interpolant is given. This result, in turn, is used to solve the model reduction problem in the Loewner framework for network systems described by a weighted graph. The problem is first solved, for a given clustering, by giving conditions on the right- and left-tangential interpolation data that yield an interpolant possessing a network structure. Thereafter, for given tangential data obtained by sampling an underlying network system, we give conditions under which we can select a clustering and construct a reduced model preserving the network structure. Finally, the results are illustrated by means of a second order diffusively coupled system and a first order network system.",

It proposes a precise parametrization of this modulation from the open-loop systems structures in order to guarantee the consistency of the closed loop energy and entropy balance equations. The results are illustrated by means of the examples of a heat-exchanger, a gas-piston system and a chemical reaction.",

      "abstract": "This paper is concerned with reduced-order control design for a class of high dimensional linear port-Hamiltonian systems stemming from the modeling of large-scale systems networks or from the discretization of distributed parameter systems. A class of dynamic controllers synthesized from low-dimensional and reduced-order models of the system are proposed. First, the controller structure and the criteria for asymptotic stability are established for a controller based on the full-order model. Then, using structural invariants, two design methods are proposed and compared: one based on a low-dimensional model of the system and the other on a reduced-order model based on modal truncation. With applications in shape control in mind, the system’s equilibrium points are parametrized using the controller parameters. It allows to establish an optimal criterion to minimize the norm of the error between the intended and achievable closed-loop equilibrium configurations. An asymptotic stability margin in terms of the full and low/reduced order models stiffness matrices is provided and related with the closed-loop transient performances. Mindlin plate with specific inputs is used to show how dynamic shape control can be achieved using the proposed approach.",

      "abstract": "Linear Quadratic differential games and their Open-Loop Nash Equilibrium (OL-NE) strategies are studied with a threefold objective. First, it is shown that the state/costate lifted system (arising from the application of Pontryagin’s Minimum Principle) is such that its behaviour restricted to the equilibrium subspace can be interpreted as the (non-power-preserving) interconnection of two cyclo-passive Port-Controlled Hamiltonian systems. Such PCH systems constitute the best response generators for each player, thus mimicking and extending the corresponding interpretation of (single-player) optimal control problems. Second, by realizing that the behaviour of the lifted dynamics off the equilibrium subspace is “irrelevant” for generating the equilibrium strategies, it is shown that such an invariant subspace can be rendered, via a suitably constructed virtual input, externally asymptotically stable while preserving the OL-NE. Finally, based on these premises we provide a closed-form gradient-descent method to solve the asymmetric coupled Riccati equations characterizing the OL-NE strategies.",

This paper proposes a sampled-data passivity-based control approach that solves the regulation problem for discrete-time underactuated mechanical systems. Moreover, in contrast to other discrete-time controllers for these systems, the proposed control design method does not require the solution of partial differential equations. To illustrate the approach, we consider three case studies with computational details and simulations.",

      "abstract": "The dynamics of irreversible thermodynamic systems have been expressed in terms of conservative contact systems where contact vector fields are generated by contact Hamiltonian functions defined on the Thermodynamic Phase Space (TPS). In this paper, we first emphasize the importance of both the Gibbs relation and the Gibbs–Duhem relation of the entropy or energy contact form in developing a first-order invariance constraint that every contact Hamiltonian function must satisfy. This novel insight is then considered together with the zero-order invariance constraint to infer solutions, thereby yielding a generalized family of contact Hamiltonian functions generating non-strict or strict contact vector fields which are equal on the associated Legendre submanifold on which the dynamics of the thermodynamic system is living. Finally, we show sufficient conditions under which the inverse images of zero by the contact Hamiltonian functions or the Legendre submanifold are globally attractive when lifting the system dynamics to the complete TPS. A simulated example is given to support the theoretical developments and to discuss the difference of the dynamic behaviours between the generated strict and non-strict contact vector fields.",

To this end, we formulate an energy-based model for these systems within the port-Hamiltonian framework. Then, we employ Lyapunov theory and the notion of contractive systems to develop control approaches in the port-Hamiltonian framework. Remarkably, these control methods eliminate the need to solve partial differential equations or implement any change of coordinates and are endowed with a physical interpretation. We also investigate the effect of coupled damping on the transient performance and convergence rate of the closed-loop system. Finally, the applicability of the proposed approaches is illustrated in two applications of electromechanical systems through simulations.",

      "abstract": "This paper proposes a passivity-based port-Hamiltonian (pH) framework for multi-agent displacement-based and rigid formation control and velocity tracking. The control law consists of two parts, where the internal feedback is to track the velocity and the external feedback is to achieve formation stabilization by steering variables of neighboring agents that prescribe the desired geometric shape. Regarding the external feedback, a general framework is proposed for stabilizing different kinds of formations (including displacement-based, distance-based, angle-based, bearing-based and heterogeneous formations) by means of the advantage that the pH model is energy-based and coordinate-free. To solve the issue that the incidence matrix is not of full column rank over cyclic graphs, the graph matrix property is used to prove the convergence to the target sets for the displacement-based formation, while for rigid formations, the algebraic conditions of infinitesimal rigidity are investigated to achieve local asymptotic stability. Furthermore, the rigid formation with heterogeneous constraints is further investigated under this framework and the local asymptotic stability is proved under a mild assumption. Simulations are performed to illustrate the effectiveness of the framework.",

      "abstract": "This paper derives two relevant results in the context of weak energy shaping for stochastic port-Hamiltonian systems (SPHS). Energy shaping is a technique systematically used to design feedback laws that shape the Hamiltonian of a controlled system to converge to a desired configuration under a general passivity condition. Such an approach has been recently extended to SPHS, but the resulting theory has limitations excluding relevant examples such as the additive noise case. However, it has been shown that the invariant measure of the SPHS allows the introduction of a weaker notion of convergence, hence obtaining a significant extension of the classical energy shaping theory for SPHS. In this paper, we continue investigating the weak energy shaping of SPHS, showing that the Fokker–Planck equation associated with an SPHS can be seen as the Fokker–Planck equation of an infinite-dimensional deterministic PHS. Moreover, we explicitly compute the invariant measure for a specific class of SPHS with additive noise.",

      "abstract": "This paper considers the general formation control problem under the port-Hamiltonian framework and proposes a method to meet the requirements of general formation control while protecting agent privacy. First, the general formation control problem is expressed as an optimization problem whose solution satisfies the requirements of the general formation. To protect the sensitive data of each agent, a distributed controller is designed through the desired general formation output dynamic, which still maintains a port-Hamiltonian form, making the Hamiltonian function the natural choice for the Lyapunov function candidate. It is then shown that the designed system converges exponentially to the global optimum of the optimization problem. Finally, simulations on an application case, namely underactuated unmanned surface vehicles with different parameters are provided to verify the effectiveness of the proposed method.",

      "abstract": "Hamiltonian neural networks (HNNs) represent a promising class of physics-informed deep learning methods that utilize Hamiltonian theory as foundational knowledge within neural networks. However, their direct application to engineering systems is often challenged by practical issues, including the presence of external inputs, dissipation, and noisy measurements. This paper introduces a novel framework that enhances the capabilities of HNNs to address these real-life factors. We integrate port-Hamiltonian theory into the neural network structure, allowing for the inclusion of external inputs and dissipation, while mitigating the impact of measurement noise through an output-error (OE) model structure. The resulting output error port-Hamiltonian neural networks (OE-pHNNs) can be adapted to tackle modeling complex engineering systems with noisy measurements. Furthermore, we propose the identification of OE-pHNNs based on the subspace encoder approach (SUBNET), which efficiently approximates the complete simulation loss using subsections of the data and uses an encoder function to predict initial states. By integrating SUBNET with OE-pHNNs, we achieve consistent models of complex engineering systems under noisy measurements. In addition, we perform a consistency analysis to ensure the reliability of the proposed data-driven model learning method. We demonstrate the effectiveness of our approach on system identification benchmarks, showing its potential as a powerful tool for modeling dynamic systems in real-world applications.",

      "abstract": "Connections between port-controlled Hamiltonian (PCH) systems and differential games are explored in this paper. First, it is shown that a given differential game can be associated with a family of PCH systems. Second, the converse is demonstrated namely that a given PCH system can be associated with a family of differential games. Third, combining these insights, we present a strategy for assigning cost matrices of a differential game, and the free parameters that arise in the context of PCH systems, to achieve a specific closed-loop behaviour, characterised by a desired closed-loop energy function. The construction of the resulting control laws only requires solving linear matrix inequalities. Finally, the latter “integrated approach” is extended to provide a method to design decentralised control laws for a class of networked multi-agent systems.",

      "abstract": "We study nonlinear singular optimal control problems of port-Hamiltonian (descriptor) systems. We employ general control-affine cost functionals that include as a special case the energy supplied to the system. We first derive optimality conditions for the case of ordinary differential equations with and without control bounds by applying the general theory to the specially structured port-Hamiltonian case, and show that this leads to elegant optimality conditions, in particular in the linear case. We then extend these results to classes of nonlinear port-Hamiltonian descriptor systems.",

      "abstract": "The SLC (solute carrier) superfamily mediates the passive transport of small molecules across apical and basolateral cell membranes in nearly all tissues. In this paper, we employ bond-graph approaches to develop models of SLC transporters that conserve mass, charge, and energy, respectively, and can be parameterized for a specific cell and tissue type for which the experimental kinetic data are available. We show how analytic expressions that preserve thermodynamic consistency can be derived for a representative four- or six-state model, given reasonable assumptions associated with steady-state flux conditions. We present details on fitting parameters for SLC2A2 (a GLUT transporter) and SLC5A1 (an SGLT transporter) to experimental data and show how well the steady-state flux expressions match the full kinetic analysis. Since the bond-graph approach will not be familiar to many readers, we provide a detailed description of the approach and illustrate its application to a number of familiar biophysical processes.",

At their core, they fulfill an energy balance relating stored, dissipated and supplied energy. To accurately resolve this energy balance in time discretizations, we propose an adaptive grid refinement technique based on a posteriori error estimation. The evaluation of the error estimator includes the computation of adjoint sensitivities. To interpret this adjoint equation as a backwards-in-time equation, we show piecewise weak differentiability of the dual variable. Then, leveraging dissipativity of the port-Hamiltonian dynamics, we present a parallelizable approximation of the underlying adjoint system in the spirit of a block-Jacobi method to efficiently compute error indicators. We illustrate the performance of the proposed scheme by means of numerical experiments showing that it yields a smaller violation of the energy balance when compared to uniform refinements and traditional step size controlled time stepping.",

      "abstract": "We study linear quadratic Gaussian (LQG) control design for linear port-Hamiltonian systems. To this end, we exploit the freedom in choosing the weighting matrices and propose a specific choice which leads to an LQG controller which is port-Hamiltonian and, thus, in particular stable and passive. Furthermore, we construct a reduced-order controller via balancing and subsequent truncation. This approach is closely related to classical LQG balanced truncation and shares a similar a priori error bound with respect to the gap metric. By exploiting the non-uniqueness of the Hamiltonian, we are able to determine an optimal pH representation of the full-order system in the sense that the error bound is minimized. In addition, we discuss consequences for pH-preserving balanced truncation model reduction which results in two different classical H ∞ -error bounds. Finally, we illustrate the theoretical findings by means of two numerical examples.",

      "abstract": "In this paper we suggest a class of quasi-port-Hamiltonian systems called Irreversible port-Hamiltonian Systems, that expresses simultaneously the first and second principle of thermodynamics as a structural property. These quasi-port-Hamiltonian systems are defined with respect to a structure matrix and a modulating function which depends on the thermodynamic relation between state and co-state variables of the system. This modulating function itself is the product of some positive function γ and the Poisson bracket of the entropy and the energy function. This construction guarantees that the Hamiltonian function is a conserved quantity and simultaneously that the entropy function satisfies a balance equation containing an irreversible entropy creation term. In the second part of the paper, we suggest a lift of the Irreversible Port-Hamiltonian Systems to control contact systems defined on the Thermodynamic Phase Space which is canonically endowed with a contact structure associated with Gibbs' relation. For this class of systems we have suggested a lift which avoids any singularity of the contact Hamiltonian function and defines a control contact system on the complete Thermodynamic Phase Space, in contrast to the previously suggested lifts of such systems. Finally we derive the formulation of the balance equations of a CSTR model as an Irreversible Port-Hamiltonian System and give two alternative lifts of the CSTR model to a control contact system defined on the complete Thermodynamic Phase Space.",

      "abstract": "In this contribution, stability and passivity properties of a class of thermodynamic processes are addressed from a thermodynamical point of view. These thermodynamic processes can be constituted by multiple spatially homogeneous dynamic subsystems modeled by ordinary differential equations. It is shown that the internal entropy production may be used as a Lyapunov function candidate to prove the isolated system stability properties and as a storage function to assess the passivity properties when the system interacts with the surroundings. In addition, it is shown that the stability condition depends on a matrix whose dimension is equal to the number of modeled dynamical phenomena taking place within the system, i.e. the number of phenomena can be smaller than the system dimension. Moreover, a port-controlled Hamiltonian representation of this class of systems based on the internal entropy production is developed. Finally, the theory proposed is applied to three study cases: a heat exchanger, a ideal gas adiabatic chemical reactor and a ideal gas jacketed chemical reactor.",

      "abstract": "Boundary controlled irreversible port-Hamiltonian systems (BC-IPHS) defined on a 1-dimensional spatial domain are defined by extending the formulation of reversible BC-PHS to irreversible thermodynamic systems controlled at the boundaries of their spatial domain. The structure of BC-IPHS has clear physical interpretation, characterizing the coupling between energy storing and energy dissipating elements. By extending the definition of boundary port variables of BC-PHS to deal with the irreversible energy dissipation, a set of boundary port variables are defined such that BC-IPHS are passive with respect to a given set of conjugated inputs and outputs. As for finite dimensional IPHS, the first and second laws of Thermodynamics are satisfied as a structural property of the system. Several examples are given to illustrate the proposed approach.",

      "abstract": "This work focuses on the investigation of the applicability of port Hamiltonian systems (PHS) approach to model chemical process plant systems and the generalization of the PHS originally proposed for reversible thermodynamic systems to irreversible thermodynamic system characterized by coupled physicochemical phenomenon and significant irreversible entropy generation. To this end, the first part of this work presents a definition and analysis of the proposed generalized class of conservative pseudo port Hamiltonian system for general open multi-input multi-output (MIMO) irreversible thermodynamic system. In the second part of the work, the generalized PHS approach is applied to multiphase process systems with coupled irreversible entropy generation. The proposed modeling framework is extended to model chemical process systems network with recycle, which is prevalent in chemical process plants.",

      "abstract": "Libration point orbits around collinear points present numerous properties which are worthwhile for space missions. Because orbits around these points are exponentially unstable, station-keeping strategies aim for periodic motion.This paper considers the problem of Lagrangian point stabilisation in the Sun-Jupiter system with non-ideal solar sail and albedo effect. Energy shaping and dissipation injection are used to stabilize the Lagrangian points, which are originally unstable. Through shaping of Hamiltonian (energy) and dissipation injection at the designed equilibrium point, we obtained that a closed-loop system is stable and asymptotic stable respectively. We discover that the orbits are stable under port- Hamiltonian control using best fit results.",

      "abstract": "Inspired by the structure of the single-clew-shaped conservative chaotic flows generated from the Nosé–Hoover oscillator, the possible local dynamic behaviors of the thermostatted oscillator are discovered near the axis of the clew-shaped chaotic flows. Based on the formalism of the port-controlled Hamiltonian system, we propose a variant of the Nosé–Hoover oscillator, which denotes a class of 3D one-thermostat systems and satisfies the canonical probability distribution. Then, three example systems are constructed to demonstrate the global structures with one-, two- and eight-clew conservative chaotic flows. Numerical results show that the different global structures depend on both the system’s Hamiltonian that determines the basic shape of clew-shaped conservative chaotic flows and the curves of equilibrium points that contain the axis of each clew.",

      "abstract": "To overcome the limitations of interconnection and damping assignment passivity-based control (IDA-PBC) in partially unknown nonlinear systems, particularly the reliance on large damping coefficients that may cause control inputs to exceed physical constraints, this paper proposes a novel adaptive neural network passivity-based control strategy incorporating a passivity-based observer. In the proposed framework, neural networks are introduced to relax the strict requirement of the desired closed-loop port-controlled Hamiltonian (PCH) model and to construct dynamic compensation mechanisms. These mechanisms are embedded into the interconnection and damping assignment passivity-based observer (IDA-PBO), resulting in an adaptive neural network IDA-PBO (ANNIDA-PBO) with enhanced dynamic compensation capability. On the control side, neural-network-based adaptive laws and compensation terms are developed to accurately approximate and compensate for unmodeled dynamics. This design alleviates the inherent limitation of conventional IDA-PBC methods that depend on large damping coefficients to achieve robustness. As a result, the proposed framework enables a well-conditioned selection of control gains within physical constraints and effectively decouples the strong dependence between robustness performance and damping parameters in standard IDA-PBC designs. Furthermore, the closed-loop system is shown to be semi-globally uniformly ultimately bounded through port-controlled Hamiltonian modeling and Lyapunov stability analysis. Finally, simulation studies on two representative nonlinear systems are conducted to validate the proposed method, demonstrating improved control accuracy and enhanced robustness against external disturbances.",

      "abstract": "The proper orthogonal decomposition reduced-order model (POD-ROM) has been widely used as a computationally efficient surrogate model in large-scale numerical simulations of complex systems. However, when it is applied to a Hamiltonian system, a naive application of the POD method can destroy the Hamiltonian structure in the reduced-order model. In this paper, we develop a new reduced-order modeling approach for Hamiltonian systems, which modifies the Galerkin projection-based POD-ROM so that the appropriate Hamiltonian structure is preserved. Since the POD truncation can degrade the approximation of the Hamiltonian function, we propose to use a POD basis from shifted snapshots to improve the approximation to the Hamiltonian function. We further derive a rigorous a priori error estimate for the structure-preserving ROM and demonstrate its effectiveness in several numerical examples. This approach can be readily extended to dissipative Hamiltonian systems, port-Hamiltonian systems, etc.",

      "abstract": "Accurate numerical simulation of dynamical systems is essential in applications ranging from particle physics to geophysical fluid flow to space hazard analysis. However, most traditional numerical methods do not account for the underlying geometric structure of the physical system, leading to simulation results that may suggest nonphysical behavior. The field of geometric numerical integration (GNI) is concerned with numerical methods that respect the fundamental physics of a problem by preserving the geometric properties of the governing differential equations. Research over the past two decades has produced GNI methods that are so accurate that they are now used for benchmarking purposes for long-time simulation of conservative dynamical systems. However, their utility for large-scale engineering problems is still an open question. This paper presents a review of structure-preserving numerical methods with focus on their engineering applications. The purpose of this paper is to provide an overview of different classes of GNI methods for mechanical systems while providing a survey of practical examples from numerical simulation of realistic engineering problems.",

      "abstract": "We present several high-order accurate finite element methods for the Maxwell’s equations which provide time-invariant, non-drifting approximations to the total electric and magnetic charges, and to the total energy. We devise these methods by taking advantage of the Hamiltonian structures of the Maxwell’s equations as follows. First, we introduce spatial discretizations of the Maxwell’s equations using mixed finite element, discontinuous Galerkin, and hybridizable discontinuous Galerkin methods to obtain a semi-discrete system of equations which display discrete versions of the Hamiltonian structure of the Maxwell’s equations. Then we discretize the resulting semi-discrete system in time by using a symplectic integrator. This ensures the conservation properties of the fully discrete system of equations. For the Symplectic Hamiltonian HDG method, we present numerical experiments which confirm its optimal orders of convergence for all variables and its conservation properties for the total linear and angular momenta, as well as the total energy. Finally, we discuss the extension of our results to other boundary conditions and to numerical schemes defined by different weak formulations.",

      "abstract": "Hamiltonian operator inference has been developed in Sharma et al. (2022) to learn structure-preserving reduced-order models (ROMs) for Hamiltonian systems. The method constructs a low-dimensional model using only data and knowledge of the functional form of the Hamiltonian. The resulting ROMs preserve the intrinsic structure of the system, ensuring that the mechanical and physical properties of the system are maintained. In this work, we extend this approach to port-Hamiltonian systems, which generalize Hamiltonian systems by including energy dissipation, external input, and output. Based on snapshots of the system’s state and output, together with the information about the functional form of the Hamiltonian, reduced operators are inferred through optimization and are then used to construct data-driven ROMs. To further alleviate the complexity of evaluating nonlinear terms in the ROMs, a hyper-reduction method via discrete empirical interpolation is applied. Accordingly, we derive error estimates for the ROM approximations of the state and output. Finally, we demonstrate the structure preservation, as well as the accuracy of the proposed port-Hamiltonian operator inference framework, through numerical experiments on a linear mass–spring-damper problem and a nonlinear Toda lattice problem.",

      "abstract": "We propose a port-Hamiltonian formulation and structure-preserving discretization of finite elasticity. The energy functional (or Hamiltonian) is based on a polyconvex representation of the stored energy and gives rise to three strain-type fields, which play the role of energy variables in the port-Hamiltonian formulation. We show that a Hu-Washizu-type extension of the variational principle of Livens can be used (i) to derive the continuous port-Hamiltonian formulation and (ii) to perform a structure-preserving spatial discretization. In particular, we show that the spatial finite element discretization of the underlying mixed formulation yields a discrete port-Hamiltonian system. Moreover, the temporal discretization of the underlying continuous formulation yields a new energy-momentum consistent framework, which accommodates alternative finite element formulations. The new framework, in particular, covers mixed finite elements that have been shown to be well suited for handling quasi-incompressible material behavior. Numerical examples are provided to evaluate the numerical performance and stability of the newly devised energy-momentum schemes.",

      "abstract": "An energy-based modeling framework for the nonlinear dynamics of spatial Cosserat rods undergoing large displacements and rotations is proposed. The mixed formulation features independent displacement, velocity and stress variables and is further objective and locking-free. Finite rotations are represented using a director formulation that avoids singularities and yields a constant mass matrix. This results in an infinite-dimensional nonlinear port-Hamiltonian (PH) system governed by partial differential–algebraic equations with a quadratic energy functional. Using a time-differentiated compliance form of the stress–strain relations allows for the imposition of kinematic constraints, such as inextensibility or shear-rigidity. A structure-preserving finite element discretization leads to a finite-dimensional system with PH structure, thus facilitating the design of an energy–momentum consistent integration scheme. Dissipative material behavior (via the generalized Maxwell model) and non-standard actuation approaches (via pneumatic chambers or tendons) integrate naturally into the framework. As illustrated by selected numerical examples, the present framework establishes a new approach to energy–momentum consistent formulations in computational mechanics involving finite rotations.",

      "abstract": "In this paper, the finite-time boundedness (FTB) and H ∞ control are discussed for a class of uncertain switched port-controlled Hamiltonian (PCH) systems via adaptive control strategies. In view of the mode-dependent matching principle, the energy-based multiple Lyapunov functions method and the mode-dependent average dwell time (MDADT) approach, sufficient conditions on the FTB are obtained for uncertain switched PCH systems by employing a set of adaptive mode-dependent state feedback controllers. Furthermore, to solve the finite-time H ∞ control for the system under consideration, a new set of mode-dependent state feedback controllers are designed to restrain both the structured uncertainties and disturbances, and sufficient conditions on the H ∞ control problem are derived for the system under a new MDADT scheme. Finally, the numerical simulations are presented to illustrate the effectiveness of the proposed finite-time adaptive control methods.",

      "abstract": "The paper proposes a tracking-error passivity-based control scheme for the asymptotic stabilization of homogeneous reaction systems. The approach uses the concept of vessel extents in the Port-Hamiltonian (PH) framework. Concretely, the extent-based representation that is obtained by linear time-invariant transformation of the reaction model is expressed as a perturbed PH system, whereby the reaction rates constitute unmatched time-varying disturbances. Two scenarios are considered. The first one assumes that the molar numbers of all species and the reaction temperature are measured and, furthermore, the kinetic model is known, while the second scenario relaxes these assumptions and requires only the measurements of a subset of the molar numbers and of the reactor temperature, but no knowledge of reaction kinetics. For the first scenario, the passivity-based method is used to compensate the disturbances, while preserving the PH structure of the error system via simple matrix factorization of the disturbances. For the second scenario, a constructive procedure is proposed to complete the space of vessel extents with the aim of computing an appropriate damping injection for the closed-loop system. It is shown that the proposed strategies guarantee that the system trajectories converge towards the desired setpoints without the need of state observation. A reaction system exhibiting non-minimum phase behavior is used to illustrate the theoretical developments. The closed-loop performance is discussed and compared to that of a PI controller.",

      "abstract": "Bayesian optimization (BO) has emerged as a powerful black-box optimization approach for complex systems, making sequential decisions through Gaussian process (GP) models to explore complex search spaces. However, conventional BO faces certain challenges when applies to optimizations of chemical systems, particularly with limited measurement data and physical constraints. This paper proposes an adaptive framework combining transfer learning with physics-informed GP to enhance BO performance for chemical process optimization. By incorporating physics-based priors through Gaussian Process Port-Hamiltonian Systems (GP-PHS) in the point-by-point transfer learning methodology, the proposed approach dynamically leverages knowledge from related source domains while satisfying physical constrains. The framework’s effectiveness is demonstrated across three chemical systems including a water tank, an electrochemical cell, and an isothermal continuous stirred tank reactor (CSTR). Results show improvements in both optimization accuracy and convergence speed compared to traditional BO methods. This proposed approach bridges the gap between data-driven optimization and physical principles, offering a robust solution for complex chemical system optimization under data scarcity.",

This literature review, with the help of more than one hundred classified references, highlights the main features, the positioning with respect to seminal works from the literature on this topic, and the advantages provided by such a framework. A focus is given on the shallow water equations and the incompressible Navier–Stokes equations in 2D, including numerical simulation results. It is also shown how it opens very stimulating and promising research lines towards thermodynamically consistent modeling and structure-preserving numerical methods for the simulation of complex fluid systems in interaction with their environment.",

      "abstract": "This paper describes the modeling of a soft actuator called an ionic polymer-metal composite (IPMC) by using distributed port-Hamiltonian (DPH) systems on multiple spatial scales. The multi-scale IPMC structure consists of an electric double layer, an electro-stress diffusion coupling and a flexible beam. The coupling of the structure can be modeled by the DPH systems with unidirectional energy flows on connecting boundaries of the subsystems, and it is called a boundary multi-scale coupling. The boundary multi-scale couplings derived from detailed models can be used for multi-scale retaining interconnections of various reduced models, e.g. numerical models with approximations.",

The control strategy is developed using Port-Hamiltonian theory and interconnection and damping assignment passivity-based control. Using energy routing, the trajectory of a virtual fully actuated plant is guided onto a vector field. A tracking controller is then used that commands the underactuated plant to follow the velocity of the virtual plant. An integral control is inserted between the two control layers, which adds robustness and disturbance rejection to the design.",

      "abstract": "The problem of modeling and control of multi-terminal high-voltage direct-current transmission systems is addressed in this paper, which contains five main contributions. First, to propose a unified, physically motivated, modeling framework — based on port-Hamiltonian representations — of the various network topologies used in this application. Second, to prove that the system can be globally asymptotically stabilized with a decentralized PI control that exploits its passivity properties. Close connections between the proposed PI and the popular Akagi's PQ instantaneous power method are also established. Third, to reveal the transient performance limitations of the proposed controller that, interestingly, is shown to be intrinsic to PI passivity-based control. Fourth, motivated by the latter, an outer-loop that overcomes the aforementioned limitations is proposed. The performance limitation of the PI, and its drastic improvement using outer-loop controls, is verified via simulations on a three-terminal benchmark example. A final contribution is a novel formulation of the power flow equations for the centralized references calculation.",

The second one is extended with the thermal diffusion. A feedforward control is used to ensure the compatibility with the actuator physical ability. An IDA-PBC feedback is proposed to improve the system stabilization and convergence speed. The controllers are validated in the simulation using RAPTOR code and tested in TCV, the result is analyzed and the followed discussion proposed the required improvement for the next experiments.",

The disturbances include persistent disturbances introduced by engine torque ripples compensation, and transient disturbances caused by transient load power demands. The disturbance rejection is achieved via singular perturbation theory. The original system is a Port-Controlled Hamiltonian (PCH) system, and the controller is designed based on interconnection and damping assignment. Experimental results verify the effectiveness of the disturbance rejection control.",

The aim is seeking the optimal point subject to voltage, current and power constraints. The algorithm is described by a continuous-time port-Hamiltonian model, and the inequality constrains are included by the use of barrier functions. The dynamics of the algorithm is studied and stability conditions are obtained. Finally, the method is used for the offshore wind integration grid in the North Sea and the interconnection with the network dynamics is tested by means of numerical simulations.",

This model reproduces the basic mechanical properties of a class of one dimensional flexible endoscope. The flexible structure and the EAP actuator are both modelled as port-Hamiltonian systems. The EAP actuator is interconnected with the flexible structure in a power preserving manner such that the global system is again a PHS. Using the obtained model, two passivity based control strategies are applied to derive the controllers which achieve a desired equilibrium configuration with desired dynamic behaviour. An experimental benchmark composed of the Ionic Polymer Metal Composites patches glued to a flexible beam is used to validate the proposed model and control law.",

      "abstract": "Reusable technology in the field of space launchers requires complex maneuvers to land a launcher first stage, requiring variable thrust from the rocket engine. The developments in electrical actuators allowed the introduction of closed-loop controllers for liquid propelled rocket engines (LPRE). While closed-loop controllers have been suggested in the literature with robustness guarantees, few stability proofs have been given. The LPRE is a complex non-linear system, rendering a direct approach to determine a Lyapunov function complex. In this paper, a reformulation of the state-space equations into a model more adapted to stability analysis is proposed, and a passivity approach is derived to prove the stability. In addition, a closed-loop controller that enforces the passivity of the system is designed, with a new equilibrium assignment. Simulated results illustrate the performances of the closed-loop controlled engine.",

      "abstract": "This paper addresses high-precision formation control for spacecraft operating in low Earth orbit, motivated by the requirements of future space interferometry missions such as SILVIA. The proposed approach formulates the relative dynamics within a port-Hamiltonian framework and introduces an Adaptive Boundary-layer Sliding Mode Control (AB-SMC) law to overcome the limitations of conventional SMC with constant gains. The key innovation lies in a dynamic, error-dependent adjustment of the sliding manifold, enhancing transient performance while guaranteeing high-precision trajectory tracking. Rigorous Lyapunov-based analysis establishes explicit ultimate bounds on the tracking error and ensures closed-loop stability, while extensive Monte Carlo simulations further validate the proposed AB-SMC compared to standard control approaches. Results show that AB-SMC achieves faster convergence, lower control effort, and sub-millimeter tracking accuracy, demonstrating its practical robustness and implementation feasibility in realistic, uncertain orbital environments while respecting low-thrust constraints.",

      "abstract": "In this communication, a control problem based on thermodynamic principles is developed to control the output temperature of a heat exchanger in an experimental setup. The system is controlled through a nonlinear output error, which is proportional to the total entropy production within the heat exchanger. A lumped-parameter model of the heat exchanger allows to define the thermodynamic control scheme, with geometric control principles, a high-gain observer and an anti-windup scheme, which provides robustness against parametric uncertainties and disturbances. To make a comparison with classical control schemes, a Ziegler–Nichols PID controller was tuned for a First Order Plus Dead Time plant approximation. The experimental setup used a National Instruments Compact FieldPoint controller, and the control scheme was programmed in a LabVIEW interface. The performance of the proposed controller was tested under two criteria: energetic performance and total tracking control error. The results show that the classical controller has a better energy-saving performance, while the thermodynamic controller has a better tracking performance, making it more suitable for applications where temperature control needs to be more precise.",

      "abstract": "In this paper, our goal is to study the regular reduction theory of regular controlled Hamiltonian (RCH) systems with symplectic structure and symmetry, and this reduction is an extension of regular symplectic reduction theory of Hamiltonian systems under regular controlled Hamiltonian equivalence conditions. Thus, in order to describe uniformly RCH systems defined on a cotangent bundle and on the regular reduced spaces, we first define a kind of RCH systems on a symplectic fiber bundle. Then we introduce regular point and regular orbit reducible RCH systems with symmetry by using momentum map and the associated reduced symplectic forms. Moreover, we give regular point and regular orbit reduction theorems for RCH systems to explain the relationships between RpCH-equivalence, RoCH-equivalence for reducible RCH systems with symmetry and RCH-equivalence for associated reduced RCH systems. Finally, as an application we regard rigid body and heavy top as well as them with internal rotors as the regular point reducible RCH systems on the rotation group SO(3) and on the Euclidean group SE(3), as well as on their generalizations, respectively, and discuss their RCH-equivalence. We also describe the RCH system and RCH-equivalence from the viewpoint of port Hamiltonian system with a symplectic structure.",

      "abstract": "The permanent magnet synchronous motor (PMSM) has several advantages over the DC motor and is gradually replacing it in the industry. The dynamics of the PMSM are described by non-linear equations; it is sensitive to unknown external disturbances (load), and its characteristics vary over time. All of these restrictions complicate the control task. Non-linear controls are required to adjust for non-linearities and the drawbacks mentioned above. This paper investigates an interconnection and damping assignment (IDA) passivity-based control (PBC) combined with a non-linear observer approach for the PMSM using the model represented in the dq-frame. The IDA-PBC approach has the inherent benefit of not canceling non-linear features but compensating them in a damped manner. The suggested PBC is in charge of creating the intended dynamic of the system, while the non-linear observer is in charge of reconstructing the recorded signals in order to compel the PMSM to track speed. The primary objective of this study is to synthesize the controller while accounting for the whole dynamic of the PMSM and making the system passive. It is performed by restructuring the energy of the proposed strategy and introducing a damping component that addresses the non-linear elements in a damped instead of deleted way, so providing a duality concept between both the IDA-PBC and the observer There are three methods for computing IDA-PBC: parametric, nonparametric, and algebraic. The parameterized IDA-PBC method is used to control the speed of the PMSM. This method uses the energy function in parameterized closed-loop in terms of some functions depending on the system’s state vector, such that the energy formation step is satisfied. Then, the original port-controlled Hamiltonian (PCH) dynamics in open-loop (OL) are equalized with the desired one in closed-loop (CL). The equalization process allows obtaining a set of solutions of the partial differential equations. The latter must be solved in terms of the parameters of the energy function of the closed-loop. Finally, the stability properties are studied using the Lyapunov theory. Generally, the proposed candidate offers high robustness, fast speed convergence, and high efficiency over the conventional benchmark strategies. The effectiveness of the proposed strategy is performed under extensive numerical investigation with MATLAB/Simulink software.",

      "abstract": "This paper presents a novel sliding-mode load frequency control (LFC) strategy for two-area thermal interconnected power system. Backstepping technique is utilized to design the controller. The sliding control method can be motivated heuristically by reasoning that one would expect better tracking performance exposed to parametric uncertainties and load disturbances. The controlled system’s asymptotic stability and the robustness of the controlled system are proved mathematically utilizing the Lyapunov theorem. Moreover, it is shown numerically that the proposed controller can diminish the intensity of the frequency oscillations caused by the load disturbance. The advantages of the proposed control approach are shown by comparing the results of proposed controller based on backstepping sliding mode control (BSMC) and other control approaches designed with the second order smc (SOSMC), observer-based BSMC (OBSMC) and port-Hamiltonian system and cascade system based proportional integral derivative (PHPID) controllers.",

      "abstract": "Many nonlinear physical phenomena, including various power systems, can be modeled, analyzed, and controlled using the framework of port-Hamiltonian systems. Moreover, this framework can offer more advanced methods to cope with modern challenges in the energy sector. This paper presents a comprehensive and systematic survey of recent studies on the application of the port-Hamiltonian approach to power systems. Over a hundred of relevant research works are reviewed to show the vast capabilities of this approach and point out its possible gaps. The works are classified according to the type of power systems under study. The analysis of the articles shows that the vast majority of them are dedicated to controller design, a much smaller part of the works deals with the modeling and stability issues, and only a few consider the problem of optimal control. Moreover, the paper discusses current challenges and future trends in this direction.",

      "abstract": "In this paper, the large-signal stability properties of a system formed of a single-phase AC Microgrid equipped with a two-level control scheme are analyzed. The aim is to show that it is possible to formally characterize the operative capacities of the controlled system when the nonlinear model that describes its dynamical behavior is considered. Thus, the presented analysis contributes to the formulation of the widely demanded methodology to analyze the large-signal stability properties of Microgrids without invoking small-signal arguments. The analyzed model includes the dynamic of the power converters associated with each distributed energy resource, an inner control law, and a power-sharing mechanism. To better illustrate the scope of the contribution, it is assumed that the Microgrid operates in islanded mode. The inner control schemes are designed using passivity-based ideas, while the power-sharing stage includes the most popular and exhaustively implemented Droop control. The large-signal stability analysis of the Microgrid is carried out by exploiting the Port-controlled Hamiltonian structure of the network and taking advantage of the stability and passivity properties of this class of dynamical systems together with the Input-to-State stability properties of the Droop scheme.",

We recall first how two port Hamiltonian systems coupled by an interface may be expressed as an port Hamiltonian systems augmented with two variables being the characteristic functions of the two spatial domains. Then we consider the case of a moving interface and show that it may be expressed as the previous port Hamiltonian system augmented with an input, being the velocity of the interface and its conjugated output variable. We then discuss the interface relations defining the dynamics of the displacement of the interface and give an illustration with the simple example of two gases coupled by a moving piston.",

      "abstract": "In this paper we present a systematic framework for modeling of power networks. The basic idea is to view the complete power network as a port-Hamiltonian system on a graph where edges correspond to components of the power network and nodes are buses. The interconnection constraints are given by the graph incidence matrix which captures the interconnection structure of the network. As a special case we focus on the system obtained by interconnecting a synchronous generator with a resistive load. We use Park's state transformation to decouple the dynamics of the state variables from the dynamics of the rotor angle, resulting in a quotient system admitting equilibria. We analyze the stability of the quotient system when it is given constant input mechanical torque and electrical excitation.",

This coupled system naturally arises in musical acoustics when viscous and thermal effects at the wall of the duct of a wind instrument are taken into account. The resulting equation, known as the Webster–Lokshin model, has variable coefficients in space, and a fractional derivative in time. This equation can be recast into the port Hamiltonian framework by using the diffusive representation of the fractional derivative in time and a multiscale state space representation. The port-Hamiltonian formalism proves adequate to reformulate this coupled system, and could enable another well-posedness analysis, using classical results from port-Hamiltonian systems theory.",

From the port-Hamiltonian description of the electrical circuits with memristors, a target dynamics is assigned to the matching equation proposed by the methodology known as Interconnection and Damping Assignment-Passivity-Based Control. The inclusion of the memristor element extends the closed-loop dynamics and it results in an extra term in the control algorithm that can be seen as a state-modulated gain. Two mechanical examples, in the form of position control systems, are included to show possible applications.",

The immersion and matching equations in both approaches have a similar structure which is exploited to derive equivalent control laws, each of them providing a different perspective on the stabilization problem. In particular, the coordinate change which renders the potential energy matching PDE in IDA-PBC an ordinary differential equation is used to define the immersion map in I&I. It is shown that the energy shaping part of the IDA-PBC controller makes the closed-loop system an interconnection of two lower-dimensional port-Hamiltonian (pH) systems in the on- and off-manifold coordinates that appear in the I&I framework. The effect of damping injection output feedback can be identified with dissipation in the off-manifold part of the interconnected system. Dissipation is propagated to the on-manifold part which results in asymptotic stability of the system's equilibrium. The particular choice of the I&I design parameters in the present example, including the unconventional definition of coordinates on the invariant manifold, provides an interesting re-interpretation of the IDA-PBC control law from the I&I perspective. Finally, a discussion on the equivalence of the two approaches is presented by examining the cases of linear mechanical systems with one unactuated pivot as well as of general linear mechanical systems.",

      "abstract": "In recent work a class of quasi port Hamiltonian system expressing the first and second principle of thermodynamics as a structural property has been defined: Irreversible port-Hamiltonian system. These systems are very much like port-Hamiltonian systems but differ in that their structure matrices are modulated by a non-linear function that precisely expresses the irreversibility of the system. In a first instance irreversible port-Hamiltonian systems are extended to encompass coupled mechanical and thermodynamical systems, leading to the definition of reversible–irreversible port Hamiltonian systems. In a second instance, the formalism is used to suggest a class of passivity based controllers for thermodynamic systems based on interconnection and Casimir functions. However, the extension of the Casimir method to irreversible port-Hamiltonian systems is not so straightforward due to the “interconnection obstacle”. The heat exchanger, a gas-piston system and the non-isothermal CSTR are used to illustrate the formalism.",

      "abstract": "This paper deals with the energy-balancing passivity-based control of linear, lossless, distributed port-Hamiltonian systems. Once inputs and outputs have been chosen to obtain a well-defined boundary control system, the problem is tackled by determining, at first, the class of energy functions that can be employed in the energy-shaping procedure, together with the corresponding boundary state-feedback control actions. To verify the existence of solutions for the closed-loop system, the equivalence between energy-balancing and energy-Casimir methods is shown. For the latter approach, the conditions for having a particular set of Casimir functions in closed-loop are given, and then the existence of the associated semigroup is studied. Since both the methods provide the same control action, the existence result determined for the energy-Casimir method is valid also for the energy-balancing controller. Simple stability is obtained by shaping the open-loop Hamiltonian, while asymptotic stability is ensured if proper “pervasive” (boundary) damping is present. In this respect, a stability criterion is discussed. The methodology is illustrated with the help of a simple example, i.e. a Timoshenko beam with full-actuation on one side, and an inertia on the other side.",

      "abstract": "For conservative mechanical systems, the so-called Caughey series are known to define the class of damping matrices that preserve eigenspaces. In particular, for finite-dimensional systems, these matrices prove to be a polynomial of one reduced matrix, which depends on the mass and stiffness matrices. Damping is ensured whatever the eigenvalues of the conservative problem if and only if the polynomial is positive for positive scalar values. This paper first recasts this result in the port-Hamiltonian framework by introducing a port variable corresponding to internal energy dissipation (resistive element). Moreover, this formalism naturally allows to cope with systems including gyroscopic effects (gyrators). Second, generalizations to the infinite-dimensional case are considered. They consist of extending the previous polynomial class to rational functions and more general functions of operators (instead of matrices), once the appropriate functional framework has been defined. In this case, the resistive element is modelled by a given static operator, such as an elliptic PDE. These results are illustrated on several PDE examples: the Webster horn equation, the Bernoulli beam equation; the damping models under consideration are fluid, structural, rational and generalized fractional Laplacian or bi-Laplacian.",

The first is taking a distributed optimal control point of view, applicable to a network of households with production devices, but also with demand side control, and with power-to-gas facilities. The expected future market structure is also considered. The second perspective considers the physics of the power grid, and the full order models that we can build. A port-Hamiltonian perspective is briefly considered, and some questions about the coupling of the two perspectives are raised.",

      "abstract": "We develop a method to simplify the partial differential equations (PDEs) associated to the potential energy for interconnection and damping assignment passivity based control (IDA-PBC) of a class of underactuated mechanical systems (UMSs). Solving the PDEs, also called the matching equations, is the main difficulty in the construction and application of the IDA-PBC. We propose a simplification to the potential energy PDEs through a particular parametrization of the closed-loop inertia matrix that appears as a coupling term with the inverse of the original inertia matrix. The parametrization accounts for kinetic energy shaping, which is then used to simplify the potential energy PDEs and their solution that is used for the potential energy shaping. This energy shaping procedure results in a closed-loop UMS with a modified energy function. This approach avoids the cancellation of nonlinearities, and extends the application of this method to a larger class of systems, including separable and non-separable port-controlled Hamiltonian (PCH) systems. Applications to the inertia wheel pendulum and the rotary inverted pendulum are presented, and some realistic simulations are presented which validate the proposed control design method and prove that global stabilization of these systems can be achieved. Experimental validation of the proposed method is demonstrated using a laboratory set-up of the rotary pendulum. The robustness of the closed-loop system with respect to external disturbances is also experimentally verified.",

Using Itô and Stratonovich integrals on Hilbert spaces, a formal mathematical description of this specific class of stochastic systems is presented, and some properties, including almost sure and weak passivity, are investigated. By considering dissipative effects, we derive a condition for SPHSs to be weakly passive. Finally, the stochastic port-Hamiltonian framework and the passivity concepts are illustrated on the example of an inhomogeneous vibrating string subject to random damping and state noises.",

      "abstract": "We investigate optimal control of linear port-Hamiltonian systems with control constraints, in which one aims to perform a state transition with minimal energy supply. Decomposing the state space into dissipative and non-dissipative (i.e. conservative) subspaces, we show that the set of reachable states is bounded w.r.t. the dissipative subspace. We prove that the optimal control problem exhibits the turnpike property with respect to the non-dissipative subspace, i.e., for varying initial conditions and time horizons optimal state trajectories evolve close to the conservative subspace most of the time. We analyze the corresponding steady-state optimization problem and prove that all optimal steady states lie in the non-dissipative subspace. We conclude this paper by illustrating these results by a numerical example from mechanics.",

      "abstract": "Stochastic infinite-dimensional port-Hamiltonian systems (SPHSs) with multiplicative Gaussian white noise are considered. In this article we extend the notion of Dirac structure for deterministic distributed parameter port-Hamiltonian systems to a stochastic ones by adding some additional stochastic ports. Using the Stratonovich formalism of the stochastic integral, the proposed extended interconnection of ports for SPHSs is proved to still form a Dirac structure. This constitutes our main contribution. We then deduce that the interconnection between (stochastic) Dirac structures is again a (stochastic) Dirac structure under some assumptions. These interconnection results are applied on a system composed of a stochastic vibrating string actuated at the boundary by a mass–spring system with external input and output. This work is motivated by the problem of boundary control of SPHSs and will serve as a foundation to the development of stabilizing methods.",

Firstly, we establish an improved FxTS criterion. Secondly, by utilizing this criterion and interconnection and damping assignment passivity-based (IDA-PBC) technique, two new FxTS results are given for PCH systems with the assumption about Hamiltonian functions. Then, a fixed-time H ∞ control design procedure is presented by using a new Lyapunov–Krasovskii (L-K) functional. Finally, the forced mathematical pendulum model with a constant time-delay shows the effectiveness of our results.",

In case of a fixed interface position, we characterize the boundary and interface conditions for which the associated port-Hamiltonian operator generates a contraction semigroup. Furthermore, we present sufficient conditions for the exponential stability of the generated C 0 -semigroup.

      "abstract": "This paper is concerned with the structure/passivity-preserving model order reduction of linear port-Hamiltonian systems. We first present, with the help of the implicit port-Hamiltonian formulation, some issues related to the standard Singular Perturbation technique. We use a simple example to analyze these aspects, paving the way for a recent approach developed to reduce the model order, called Beyond Singular Perturbation. This technique leverages the description of the dominant evolution of the original system whenever a time-scale separation is present among its dynamics. With this tool, we study the system’s Hamiltonian time evolution, showing that we can successfully reconstruct the dominant behavior of the Hamiltonian by slightly modifying the storage function of the resulting reduced-order model. We conclude the work with a discussion about the class of input signals that allow a good performance of the reduced-order model.",

      "abstract": "This work investigates the passivity-based control of a class of underactuated mechanical systems subject to matched disturbances that enter the dynamics through a state-dependent vector-valued function that is not integrable. The main contributions include a new passivity-based controller with a dynamic extension, designed with the port-Hamiltonian formalism, and, most importantly, a suitably defined function of the states, serving the purpose of estimating the disturbance parameters while circumventing the usual integrability assumption. A corresponding controller is designed with the Lagrangian formalism, and key differences are discussed. Numerical simulations on two examples demonstrate the effectiveness of the new controllers.",

      "abstract": "Energy-based modeling is often very appropriate for physical system modeling for development and analysis of multi domain dynamic system models. One such tool for modelling of system is bond graph (BG), which allows to model complex system, with clear interconnection rules and preserving the physical structure of the system. In various engineering system, operation is carried out on various time scale. One such area of generic system is microgrid, where multidisciplinary microgrid components operating on various time scales. In such hybrid system, flows and efforts comprise a very good choice of variables to link components for system stability and performance analysis. Since components are typically connected through various power electronics devices, mathematical modeling capable of capturing high frequency behavior is of utmost concern in stability analysis. Solid state transformer (SST) is one such device playing a key role in bi-directional power flow between the grid and various renewable sources. This paper proposes the use of the BG approach to recognize the energy representation of the microgrid in port-Hamiltonian form by looking at the energy transformation aspects of microgrid components. The port-controlled Hamiltonian systems (PCHS) are the mathematical description of bond graphs which allows integration of subsystems of hybrid microgrid using energy as the linking concept. To illustrate the utility of BG in hybrid systems, basic PI controller is implemented. The aim of the paper is to show how to model complex systems in bond graph domain.",

      "abstract": "Superconducting magnetic energy storage (SMES) has been widely used to stabilize the power fluctuations of wind farms to achieve efficient grid connections. However, conventional converters can rarely satisfy the high power quality requirements of a power grid. Compared to other convertors, a three-level T-type converter (3LT2C) can improve the output performance and operating efficiency of a system and reduce the voltage stress and conduction loss of power switches. Therefore, the 3LT2C has broad application prospects for electric power storage. A precise control strategy is also necessary for the practical application of an SMES system, which has significant nonlinear dynamic characteristics. Energy-shaping (ES) control is a nonlinear control method that is based on the theoretical design of interconnection and damping assignment (IDA), which considers both the nonlinear nature of a system and the energy perspective. This study proposes an ES control strategy for an SMES system based on a 3LT2C. Mathematical models and port-controlled Hamiltonian (PCH) models of the SMES are established. The ES control strategy of the SMES system is designed based on a feedback interconnection structure through analysis of the novel SMES topology. Finally, the effectiveness of the control strategy and the proposed topology are verified through simulations.",

      "abstract": "This paper proposes a method to control low frequency circulating currents generated in parallel interleaved converters. In this configuration, inverters are parallelized using magnetically linked inductors. Generally, to improve the harmonic content of the output voltage, carrier interleaving is used. This results in a higher circulating current (differential mode current) to flow through the two Voltage Source Converters (VSCs). High frequency components of circulating currents are efficiently reduced by the mutual inductance of the Coupled Inductors (CI). However, CI cannot efficiently filter the low frequency components. When the uncontrolled circulating currents become too high; they lead to CI saturation, higher switching losses, and degrade the overall performances of the converter. Therefore, this paper presents a global control strategy for a grid-connected parallel interleaved converter based on the concept of Port Controlled Hamiltonian (PCH). With this controller, active and reactive powers delivered to the grid are efficiently controlled. In addition, the controller considerably reduces the value of the low frequency circulating current. Converter performances are evaluated by simulation and compared with the classical PI control and the Linear Quadratic (LQ) control. An experimental setup was developed to verify the feasibility of the proposed system. Results obtained from experiments show a good agreement with the simulation, confirming the performances of the proposed method.",

      "abstract": "This paper proposes a direct power control for electrical energy storage systems (EESS) in ac microgrids. This strategy allows managing instantaneous active and reactive power without using a conventional inner-loop current regulator and without a phase-locked loop, increasing the reliability of the system while reducing investment costs. PI passivity-based control (PI-PBC) is selected to control the direct power model of EESS. This is because their models exhibit a port-Hamiltonian formulation in open-loop, and PI-PBC exploits this formulation to design a PI controller, which guarantees global asymptotically stability in closed-loop in the sense of Lyapunov. Simulations tested the proposed model in a microgrid and compared with conventional vector oriented controls in a dq reference frame and a direct power model controlled via feedback linearization (FL). PI-PBC has a better performance than other two controllers in all considered scenarios. Simulation results have conducted through MATLAB/SIMULINK software by using the SimPowerSystem toolbox.",

      "abstract": "In this paper, a meshed DC microgrid control architecture whose goal is to manage load balancing and efficient power distribution is introduced. A novel combination of port-Hamiltonian (PH) modeling with differential flatness and B-splines parametrization is introduced and shown to improve the microgrid's performance. A three layer supervision structure is considered: (i) B-spline parametrized flat output provide continuous profiles for load balancing and price reduction (high level); (ii) the profiles are tracked through a MPC implementation with stability guarantees (medium level); (iii) explicit switching laws applied to the DC/DC converters ensure appropriate power injection. Each level functions at a different time-scale (from slow to fast), and the control laws are chosen appropriately. The effectiveness of the proposed approach is evaluated by simulations over a DC microgrid composed by a collection of solar panels (PV), an energy storage system (ES), a utility grid (UG) and a consumers’ demand.",

      "abstract": "This paper presents a model for stabilizing multi-terminal high voltage direct-current (MT-HVDC) networks with constant power terminals (CPTs) interfaced with power electronic converters. A hierarchical structure of hierarchical control is developed, which guarantees a stable operation under load variations. This structure includes a port-Hamiltonian formulation representing the network dynamics and a passivity-based control (PBC) for the primary control. This control guarantees stability according to Lyapunov’s theory. Next, a convex optimal power flow formulation based on semidefinite programming (SDP) defines the control’s set point in the secondary/tertiary control. The proposed stabilization scheme is general for both point-to-point HVDC systems and MT-HVDC grids. Simulation results in MATLAB/Simulink demonstrate the stability of the primary control and the optimal performance of the secondary/tertiary control, considering three simulation scenarios on a reduced version of the CIGRE MT-HVDC test system: (i) variation of generation and load, (ii) short-circuit events with different fault resistances and (iii) grid topology variation. These simulations prove the applicability and efficiency of the proposed approach.",

      "abstract": "As the penetration of renewable energy sources using power electronics as an interface method in power systems increases, traditional synchronous generators are gradually being replaced, leading to a continuous reduction in power system inertia and a decrease in frequency support and oscillation suppression. In order to enhance the inertia support of VSC-HVDC systems, this paper proposes an interconnection and damping assignment passivity-based control (IDA-PBC) strategy based on inertia emulation. The strategy achieves inertia emulation control by releasing or absorbing inertial power through the DC capacitor, thereby suppressing frequency oscillations. As the inertial power released by capacitor charging and discharging is small and cannot maintain stability between interconnected power systems during large disturbances, IDA-PBC reshapes the energy of the system by injecting an interconnection matrix and a damping matrix to achieve matching of voltage and frequency between systems, which in combination with inertial simulation can improve the interconnectivity and stability between systems. Also in inertia emulation designs, PLLs are unable to accurately track system frequencies in weak grids and passive control can quickly adjust the output of the VSC-HVDC to achieve fast tracking. This fast response capability helps to reduce system oscillations and frequency excursions and improves system stability. Results from simulation and RT-LAB hardware-in-the-loop (HIL) testing attest to the efficacy of this solution.",

      "abstract": "In order to address the issue of controller stability reduction caused by the fixed damping injection method, this paper provides a variable damping injection for the passive control strategy optimization method in the superconducting magnetic energy storage (SMES) system based on the capacitor-inductor-inductor-capacitor (CLLC) topology structure. First, the paper analyzes the CLLC-SMES system's charging and discharging principle and gives a port-controlled Hamiltonian-with-dissipation (PCHD) model for the passive controller. Then, the range of damping values is clarified, and the attention is paid to understanding how changes in damping parameters affect system stability on both the alternating current (AC) and direct current (DC) sides. After that, using the self-learning methodology of the back propagation (BP) neural network, a variety of damping parameters and optimization goals are added, and the BP neural network controllers on the AC and DC side are created to provide the variable damping injection for the passive system. Finally, the active and reactive power, the AC side and DC side voltage, and the superconducting magnet discharge current are computed and implemented in a simulation model of the CLLC-SMES passive control system based on the BP neural network. According to the simulation results, the system with the variable damping injection reaches the steady state earlier and has less overshoot than the system with the fixed damping injection. Additionally, the optimization method of the passive control strategy with the variable damping injection based on the BP neural network is capable of improving the power quality and system stability.",

      "abstract": "Distributed control for large-scale multi-robot systems remains challenging under sparse and time-varying communication graphs, where one-hop interaction models may miss long-range task context and homogeneous policies may produce overly similar behaviors. This paper proposes PIMARL–V–Cycle, a physics-informed multi-agent reinforcement learning framework that embeds a fixed-graph V-shaped multi-hop attention backbone into a port-Hamiltonian policy actor. The V-shaped backbone repeatedly applies sparse graph attention on the communication graph to enlarge the receptive field, while skip connections preserve local geometric information and agent-specific cues. The decoder then synthesizes actions through a structured port-Hamiltonian parameterization, and the overall policy is trained with Soft Actor-Critic under centralized training and decentralized execution using a graph-structured replay buffer. We evaluate the method on cooperative navigation and spatial sampling tasks in VMAS and assess communication robustness in a Robotarium simulator with communication delays, packet losses, and noise. In the tested settings, PIMARL–V–Cycle improves mean coordination performance over MLP, graph self-attention, and the original physics-informed baseline, and it transfers to larger test teams within the reported range without additional training. Qualitative observations further suggest that skip-connected multi-hop aggregation reduces the herding behavior observed in the baseline during large-scale exploration. The results demonstrate the value of combining V-shaped long-range graph perception with port-Hamiltonian action decoding for scalable and robust multi-robot coordination.",

      "abstract": "In this paper, new results of plasma ι-profile and β control on TCV, using total plasma current I p , and ECCD (Electron Cyclotron heating and Current Drive) heating source have been discussed. The control model is governed by the resistive diffusion equation coupled with the thermal transport equation, written in PCH (Port-Controlled Hamiltonian) formulation. The IDA-PBC (Interconnection and Damping Assignment – Passivity based Control) controller is developed and tested on simulation as well as on TCV real plant. Two test scenarios are considered: ι control only, and ι and β control. The spatial distributions of ECCD profiles are pre-defined and only input powers are used for control design. Thus, a stationary control is defined in order to consider all non-linearity and actuator constraint, and a linear feedback IDA-PBC will ensure the convergence speed and the robustness of the closed-loop system. The obtained results are encouraging towards using routinely such plasma advanced control algorithm in a near future.",

This setting includes degenerate Lagrangian systems and systems with both holonomic and nonholonomic constraints, as well as networks of Lagrangian mechanical systems. The definition of implicit Lagrangian systems with a configuration space Q makes use of Dirac structures on T ∗ Q that are induced from a constraint distribution on Q as well as natural symplectomorphisms between the spaces T ∗ T Q , T T ∗ Q , and T ∗ T ∗ Q . Two illustrative examples are presented; the first is a nonholonomic system, namely a vertical disk rolling on a plane, and the second is an L–C circuit, a degenerate Lagrangian system with holonomic constraints.",

As a control system with the constraint taken into account, this model is formulated as a port-controlled Hamiltonian system defined on the cotangent bundle of the shape space for the jointed cylinders. A control is then designed as a function on the cotangent bundle, according to a standard procedure. Thus, the equations of motion are determined on the cotangent bundle together with the control. The whole motion as a vibrational motion of the falling cat is obtained after integrating the constraint equation of the vanishing total angular momentum. An example of the falling cat is given in which the model turns a somersault to approach a target state in equilibrium with an expected rotation after finishing a vibrational motion.",

Thus, in order to describe uniformly CH systems defined on a cotangent bundle and on the optimal reduced spaces, we first define a kind of CH systems on a Poisson fiber bundle. Then we introduce the optimal point, optimal orbit, and regular Poisson reducible CH systems with symmetry by using the optimal momentum map and reduced Poisson tensors (or reduced symplectic forms). Moreover, we give some optimal reduction theorems for CH systems to explain the relationships between OpCH-equivalence, OoCH-equivalence, RPR-CH-equivalence for optimal reducible CH systems with symmetry and CH-equivalence for associated optimal reduced CH systems. Finally, we describe the CH system and CH-equivalence from the viewpoint of port Hamiltonian system with a Poisson structure, and give two examples to state theoretical results of optimal point reduction of CH systems.",

      "abstract": "This paper addresses the issue of structure-preserving discretization of open distributed-parameter systems with Hamiltonian dynamics. Employing the formalism of discrete exterior calculus, we introduce a simplicial Dirac structure as a discrete analogue of the Stokes–Dirac structure and demonstrate that it provides a natural framework for deriving finite-dimensional port-Hamiltonian systems that emulate their infinite-dimensional counterparts. The spatial domain, in the continuous theory represented by a finite-dimensional smooth manifold with boundary, is replaced by a homological manifold-like simplicial complex and its augmented circumcentric dual. The smooth differential forms, in discrete setting, are mirrored by cochains on the primal and dual complexes, while the discrete exterior derivative is defined to be the coboundary operator. This approach of discrete differential geometry, rather than discretizing the partial differential equations, allows to first discretize the underlying Stokes–Dirac structure and then to impose the corresponding finite-dimensional port-Hamiltonian dynamics. In this manner, a number of important intrinsically topological and geometrical properties of the system are preserved.",

      "abstract": "In this paper, we explore dynamics of the nonholonomic system called vakonomic mechanics in the context of Lagrange–Dirac dynamical systems using a Dirac structure and its associated Hamilton–Pontryagin variational principle. We first show the link between vakonomic mechanics and nonholonomic mechanics from the viewpoints of Dirac structures as well as Lagrangian submanifolds. Namely, we clarify that Lagrangian submanifold theory cannot represent nonholonomic mechanics properly, but vakonomic mechanics instead. Second, in order to represent vakonomic mechanics, we employ the space T Q × V ∗ , where a vakonomic Lagrangian is defined from a given Lagrangian (possibly degenerate) subject to nonholonomic constraints. Then, we show how implicit vakonomic Euler–Lagrange equations can be formulated by the Hamilton–Pontryagin variational principle for the vakonomic Lagrangian on the extended Pontryagin bundle ( T Q ⊕ T ∗ Q ) × V ∗ . Associated with this variational principle, we establish a Dirac structure on ( T Q ⊕ T ∗ Q ) × V ∗ in order to define an intrinsic vakonomic Lagrange–Dirac system. Furthermore, we also establish another construction for the vakonomic Lagrange–Dirac system using a Dirac structure on T ∗ Q × V ∗ , where we introduce a vakonomic Dirac differential. Finally, we illustrate our theory of vakonomic Lagrange–Dirac systems by some examples such as the vakonomic skate and the vertical rolling coin.",

      "abstract": "In this paper, we present a Lagrangian variational formulation for nonequilibrium thermodynamics. This formulation is an extension of Hamilton’s principle of classical mechanics that allows the inclusion of irreversible phenomena. The irreversibility is encoded into a nonlinear phenomenological constraint given by the expression of the entropy production associated to all the irreversible processes involved. From a mathematical point of view, our variational formulation may be regarded as a generalization to nonequilibrium thermodynamics of the Lagrange–d’Alembert principle used in nonlinear nonholonomic mechanics, where the conventional Lagrange–d’Alembert principle cannot be applied since the nonlinear phenomenological constraint and its associated variational constraint must be treated separately. In our approach, to deal with the nonlinear nonholonomic constraint, we introduce a variable called the thermodynamic displacement associated to each irreversible process. This allows us to systematically define the corresponding variational constraint. In Part I, our variational theory is illustrated with various examples of discrete systems such as mechanical systems with friction, matter transfer, electric circuits, chemical reactions, and diffusion across membranes. In Part II of the present paper, we will extend our variational formulation of discrete systems to the case of continuum systems.",

This variational formulation extends Hamilton’s principle to allow the inclusion of irreversible processes in the dynamics. The irreversibility is encoded into a nonlinear nonholonomic constraint given by the expression of entropy production associated to all the irreversible processes involved. In Part II, we develop this formulation for the case of continuum systems by extending the setting of Part I to infinite dimensional nonholonomic Lagrangian systems. The variational formulation is naturally expressed in the material representation, while its spatial version is obtained via a nonholonomic Lagrangian reduction by symmetry. The theory is illustrated with the examples of a viscous heat conducting fluid and its multicomponent extension including chemical reactions and mass transfer.",

After recalling a framework for nonlinear port-Hamiltonian systems, we model each circuit component as an individual port-Hamiltonian system. The overall circuit model is then derived by considering a port-Hamiltonian interconnection of the components. We further compare this modeling approach with standard formulations of nonlinear electrical circuits.",

Starting from the group of diffeomorphisms as a configuration space for the fluid, the Stokes–Dirac structure is derived by Poisson reduction and then augmented by boundary ports and distributed ports. The additional boundary ports have been shown to appear naturally as surface terms in the pairings of dual maps, always neglected in standard Hamiltonian theory. The port-Hamiltonian model presented in Part I corresponded only to the kinetic energy of the fluid and how its energy variables evolve such that the energy is conserved. In Part II, we utilize the distributed port of the kinetic energy port-Hamiltonian system for representing a number of fluid-dynamical systems. By adding internal energy we model compressible flow, both adiabatic and isentropic, and by adding constraint forces we model incompressible flow. The key tools used are the interconnection maps relating the dynamics of fluid motion to the dynamics of advected quantities.",

The first novelty of the presented model is the inclusion of non-zero energy exchange through, and within, the spatial boundaries of the domain containing the fluid. The second novelty is that the port-Hamiltonian model is constructed as the interconnection of a small set of building blocks of open energetic subsystems. Depending only on the choice of subsystems one composes and their energy-aware interconnection, the geometric description of a wide range of fluid dynamical systems can be achieved. The constructed port-Hamiltonian models include a number of inviscid fluid dynamical systems with variable boundary conditions. Namely, compressible isentropic flow, compressible adiabatic flow, and incompressible flow. Furthermore, all the derived fluid flow models are valid covariantly and globally on n-dimensional Riemannian manifolds using differential geometric tools of exterior calculus.",

      "abstract": "We introduce the geometric structure underlying the port-Hamiltonian models for distributed parameter systems exhibiting moving material domains. The first part of the paper aims at introducing the differential geometric tools needed to represent infinite-dimensional systems on time–varying spatial domains in a port–based framework. A throughout description on the way we extend the structure presented in the seminal work [25], where only fixed spatial domains were considered, is carried through. As application of the proposed structure, we show how to model in a completely coordinate-free way the 3D fluid–structure interaction model for a rigid body immersed in an incompressible viscous flow as an interconnection of open dynamical subsystems.",

In particular, we show that similar to the symplectic case, one can prove a nonsqueezing theorem for cosymplectomorphisms on R 2 m + 1 . Using this nonsqueezing theorem, we can define the concept of “cosymplectic capacity”. We show that the set of all cosymplectic capacities on cosymplectic manifolds of dimension 2 m + 1 has a close relationship with the set of all symplectic capacities on symplectic manifolds of dimension 2m. Furthermore, we study the relationship between fixed points of cosymplectomorphisms and symplectomorphisms.",

      "abstract": "In this paper, we present port-Hamiltonian formulations of the incompressible Euler equations with a free surface governed by surface tension and gravity forces, modelling e.g. capillary and gravity waves and the evolution of droplets in air. Three sets of variables are considered, namely ( v , Σ ) , ( η , ϕ ∂ , Σ ) and ( ω , ϕ ∂ , Σ ) , with v the velocity, η the solenoidal velocity, ϕ ∂ a potential, ω the vorticity, and Σ the free surface, resulting in the incompressible Euler equations in primitive variables and the vorticity equation. First, the Hamiltonian formulation for the incompressible Euler equations in a domain with a free surface combined with a fixed boundary surface with a homogeneous boundary condition will be derived in the proper Sobolev spaces of differential forms. Next, these results will be extended to port-Hamiltonian formulations allowing inhomogeneous boundary conditions and a non-zero energy flow through the boundaries. Our main results are the construction and proof of Dirac structures in suitable Sobolev spaces of differential forms for each variable set, which provides the core of any port-Hamiltonian formulation. Finally, it is proven that the state dependent Dirac structures are related to Poisson brackets that are linear, skew-symmetric and satisfy the Jacobi identity.",

      "abstract": "Permanent Magnet Synchronous Motors (PMSMs) are widely employed in high-performance drive applications due to their superior efficiency and dynamic capabilities. However, their control remains challenging owing to nonlinear dynamics, parameter variations, and unmeasurable external disturbances, particularly load torque fluctuations. This study proposes an enhanced Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) scheme, formulated within the port-controlled Hamiltonian (PCH) framework, to address these limitations. A nonlinear disturbance observer is embedded to estimate and compensate, in real time, for lumped mismatched disturbances arising from parameter uncertainties and external loads. Additionally, a flatness-based control strategy is employed to generate the desired current references within the nonlinear drive system, ensuring accurate tracking of time-varying speed commands. This integrated approach preserves the system’s energy-based structure, enabling systematic stability analysis while enhancing robustness. The proposed control architecture also maintains low complexity with a limited number of tunable parameters, facilitating practical implementation. Simulation and experimental results under various operating conditions demonstrate the effectiveness and robustness of the proposed method. Comparative analysis with conventional proportional-integral (PI) control and standard IDA-PBC strategies confirms its capability to handle disturbances and maintain dynamic performance.",

      "abstract": "Mathematical modeling of real-world physical systems requires the consistent combination of a multitude of physical laws and phenomenological models. This challenging task can be greatly simplified by hierarchically decomposing systems into ultimately simple components. Moreover, the use of diagrams for expressing the decomposition helps make the process more intuitive and facilitates communication, even with non-experts. As an important requirement, models have to respect fundamental physical laws such as the first and the second law of thermodynamics. While some existing modeling frameworks make such guarantees based on structural properties of their models, they lack a formal graphical syntax. We present a compositional and thermodynamically consistent modeling language with a graphical syntax. In terms of its semantics, we essentially endow port-Hamiltonian systems with additional structural properties and a fixed physical interpretation, ensuring thermodynamic consistency in a manner closely related to the metriplectic or GENERIC formalism. While port-Hamiltonian systems are inspired by graphical modeling with bond graphs, neither the link between the two, nor bond graphs themselves, can be easily formalized. In contrast, our syntax is based on a specialization of the well-studied operad of undirected wiring diagrams. By combining a compositional, graphical syntax with an energy-based, thermodynamic approach, the presented modeling language simplifies the understanding, reuse, and modification of complex physical models.",

We will distinguish the case where the Lagrangian or the Hamiltonian depend on derivative variables (jet-variables) of first-order and the case where second-order derivatives appear. This distinction will be important for the correct determination of the boundary conditions in the Lagrangian scenario and for the investigation of possible boundary ports in the Hamiltonian picture. The derivation of the partial differential equations and the boundary terms/ports will be accomplished in a geometric fashion by using the so-called Cartan-form. We visualize our results by mechanical examples such as beams and plates.",

As for the finite dimensional case, a feedback control transforms the original model into a closed loop target Hamiltonian model. Both distributed control and boundary control are used. The finite rank distributed control is determined to solve an average IDA-PBC matching equation. A backstepping boundary control is used to stabilize the matching error. The control model chosen to illustrate the approach is the so-called resistive diffusion equation for the radial diffusion of the poloidal magnetic flux.",

      "abstract": "This paper illustrates a general synthesis methodology of asymptotic stabilising, energy-based, boundary control laws, that is applicable to a large class of distributed port- Hamiltonian systems. Similarly to the finite dimensional case, the idea is to design a state feedback law able to perform the energy-shaping task, i.e. able to map the open-loop port- Hamiltonian system into a new one in the same form, but characterised by a new Hamiltonian with a unique and isolated minimum at the equilibrium. Asymptotic stability is then obtained via damping injection on the boundary, and is a consequence of the La Salle's Invariance Principle in infinite dimensions. The general theory is illustrated with the help of a simple concluding example, i.e. the boundary stabilisation of a transmission line with distributed dissipation.",

More specifically we show here that a pseudo Hamiltonian representation with R(x) > 0 can be obtained by considering the Brayton-Moser formulation via a unified potential function that verifies a thermodynamic evolution criterion. As a consequence, it gives additional degrees of freedom (i.e. to construct alternate pseudo Hamiltonian models with new passive outputs) usable for further studies on the control design. A representative example of irreversible processes via the non isothermal continuous stirred tank reactor model is used to illustrate the theoretical developments.",

      "abstract": "On this work is shown how to derive a structural representation of a class of thermo-mechanical systems in the Port Hamiltonian framework in order to express explicitly the dissipation along the trajectories of the dynamics. To achieve this goal the entropy is used as the storage function. The dissipation structures are correlated with irreversible processes, while the conservative processes are correlated with reversible or isentropic processes. Finally, three study cases are presented: the first one is an adiabatic gas-piston system, the second is an adiabatic two chambers gas-piston-gas system and the last one is an adiabatic liquid-pendulum system.",

      "abstract": "Port-Hamiltonian (PH) systems are energy-rooted representations of dynamical systems whichallow, through energy shaping, to design controller based on physical considerations. Since,bioreactions kinetics are based on data fitting, the obtention of a passive or a PH representationof a continuous bioreactor is not straightforward. Its is shown that an adequate change ofcoordinates and the use of appropriate energy functions allow for a pseudo-PH formulation ofthe dynamics of continuous fermenters. Different candidate energy functions are being testedand an adaptive controller is designed to cope with uncertainties on the specific growth rate.Simulations show the relevance of the approach.",

      "abstract": "This paper aims at developing a Brayton-Moser analogue of an infinite-dimensional system in the port-Hamiltonian framework, defined with respect to a Stokes-Dirac structure. It is shown that such a formulation leads to defining alternative passive maps, which differ from those in the port-Hamiltonian framework via a “power-like” function called the mixed-potential function. This mixed-potential function can also be used for stability analysis. We present our results for a general port-Hamiltonian system, with Maxwell's equations and the transmission line, with nonzero boundary conditions, as examples.",

      "abstract": "This paper is concerned with stability analysis of delay feedback structures within discrete port-Hamiltonian framework. We introduce a discrete dynamics that approximates linear port-Hamiltonian systems and is passive relatively to the same storage and dissipation functions. Stability of interconnected discrete systems is then addressed when considering time-varying delay feedback interconnection structure. A delay bounds-dependent stability condition is derived for variable and bounded delayed interconnection, reducing to a delay-independent condition for constant delay. A sufficient condition is formulated in terms of a feasibility problem under LinearMatrix Inequality (LMI) constraints. It is noticeable that the LMI parameters linearly depend on the network characteristics (damping and input matrices). Moreover, computing and storing past history of the discrete flow is no longer required. A numerical example illustrates the feasibility of the approach.",

This paper shows that the gradient method admits a Brayton-Moser and a port-Hamiltonian representation. In fact, its dynamics can be interpreted as a interconnection of multiple (port-Hamiltonian) passive systems, which plays a key role in proving asymptotic stability of the method. As an application to smart grids, this paper studies the problem of frequency regulation in power grids, while maximizing the social welfare. By applying the gradient method, we obtain a real-time dynamic pricing model in port-Hamiltonian form. By coupling with the port-Hamiltonian description of the physical network we obtain a closed-loop port-Hamiltonian system, which properties are exploited to prove asymptotic stability to the set of optimal points.",

      "abstract": "The use of beams and similar structural elements is finding increasing application in many areas, including micro and nanotechnology devices. For the purpose of buckling analysis and control, it is essential to account for nonlinear terms in the strains while modeling these exible structures. Further, in modeling of micro and nanotechnology devices, the micro length scale parameter effects can be accounted by the use of a 2 dimensional stress-strain relationship. This paper studies the buckling effect for a slender, vertical beam with a tip-mass at one end and fixed on a movable platform at the other. For the purpose of illustration, the movable platform is assumed to be a cart. Accounting for a 2 dimensional stress-strain relationship, nonlinear expressions for strains, and incorporating an inextensibility constraint of the beam, the Hamiltonian equations of motion are obtained. The equations of motion are then cast in a port-Hamiltonian form with appropriately defined flows and efforts. We then carry out a preliminary modal analysis of the system to describe candidate post-buckling configurations and study the stability properties of these equilibria. The vertical configuration of the beam under the action of gravity is without loss of generality, since the objective is to model a potential field that determines the equilibria.",

      "abstract": "A quaternion representation is often used to describe the attitude of a rigid body type spacecraft since it does not have any singular point whereas the conventional Euler angle description intrinsically has one. However, the dynamical equation with quaternions become more complicated than those described by Euler angles. The scope of this paper is to provide a basis of modeling and control of those systems using port-Hamiltonian system formulation to remove some of those difficulties in control of those systems. A stabilization procedure based on passivity based control is proposed and a sufficient condition for artificial potential energy are derived for a class of simple systems with quaternions.",

To reduce the difficulty, in this paper, we derive quasi-optimal regulators for nonholonomic systems such as a typical chained system with some restriction to the form of control inputs. To achieve the solution, we employ a notion of stability in roughness, which is Lyapunov stability theory for dynamical systems driven by rough paths. The rough paths are capable of transforming some nonholonomic systems into holonomic systems with “hidden control inputs”. Thus, the control problems are simplified in exchange for the degradation of some control performances.",

On the other hand, power-based Dirac structures can be naturally generalised by the use of operators in a similar fashion as Tellegen's theorem is generalised by the use of so-called Kirchhoff voltage and current operators. The purpose of such operators is to derive, from one set of efforts and ows that belong to a given Dirac structure, another set of quantities that also belong to the same Dirac structure. Examples of such operators are differentiation and integration with respect to time, Fourier and Laplace transform, or replacing the efforts and ows by their complex-valued analytical signal representations. Hence, many different representations of the same Dirac structure are possible. This opens up the possibility to formalise a whole new family of port-Hamiltonian representations beyond the usual time-domain and power-based setting.",

      "abstract": "The main contribution of this paper is a general methodology for the definition of a new passive output that is instrumental for the stabilisation of a large class of distributed port-Hamiltonian systems defined on a one-dimensional spatial domain. This new output is in fact employed within the control by interconnection via Casimir generation paradigm for the synthesis of boundary stabilising control laws. It is well-known that this control technique is limited by the so-called \"dissipation obstacle\" when the passive controller is interconnected to the natural input/output port of the plant. When it is the case, it is impossible to shape the energy of the system along the directions in which dissipation is present. In this paper, it is shown how these limitations can be removed by interconnecting the boundary controller to the new passive output of the system, and then how the control by interconnection can easily deal with the dissipation obstacle. The general theory is illustrated with the help of a concluding example, the boundary stabilization of the shallow water equation.",

We utilize a change of variables that transforms the port-Hamiltonian system into one with constant mass-inertia matrix, and we use an interaction matrix that includes the depth information together with the image features variables of the image plane. We develop a control strategy that renders a closed-loop system that is port-Hamiltonian. The introduced approach is applied to a two degrees of freedom robot arm problem, and simulation results are provided.",

The novelty of the presented results lies in the fact that, contrary to the usual practice of establishing these properties for a given circuit, generic features of this class of networks are interpreted in terms of interconnections of the circuit elements to conceive specific topologies for which both stability and consensus are guaranteed. Fundamental for this achievement is the Hamiltonian structure exhibited by the circuits, since the features enjoyed by this kind of dynamical systems allow to systematically state the structural (interconnection) properties under which stability is assured while conditions to conclude consensus are derived from the analysis of its equilibria.",

The system includes the mechanical part, a Salient Permanent Magnet Synchronous Machine (SPMSM), a battery energy storage unit, a super-capacitor, a solar panel (PV) generation unit as well as the corresponding converters to DC-links. This microgrid is connected to a three-phase utility (external) grid. A port-Hamiltonian model is proposed for the system. It includes the descriptions of nonlinear characteristics and the limitations for each components as well as some typical operation demands.",

      "abstract": "It is well—known that the presence of dissipation hampers our ability to shape the energy of port—Hamiltonian systems using control.by.interconnection methods—a phenomenon called the dissipation obstacle. In particular, the Casimir functions that are used to shift the energy function cannot depend on the coordinates where dissipation is present if we use, as is usually the case, passive controllers. Recently, it was proposed to relax the latter condition, namely, to use controllers that inject energy into the system to be able to create the required Casimir functions. In this note we prove that, alas, even if the Casimirs can be created with active controllers the dissipation obstacle stymies the possibility to assign an energy function with the minimum at an equilibrium point. As a corollary we prove that the subtle, deleterious effect of pervasive dissipation does not only stem from the inability of the controller to inject the (infinite) energy required for stabilization—as it was conjectured in earlier publications",

      "abstract": "The main purpose of this paper is to investigate the robustness of tracking controllers for mechanical systems vis—à—vis external disturbances. The controllers designed are obtained by modifying a change of coordinates recently proposed for robust energy shaping controller. This type of change of coordinates allows to assign damping in all the states when the closed loop is written in port{Hamiltonian form. This feature simplify the stability analysis by ensure that the Hamiltonian function is a strict Lyapunov function of the closed loop. Moreover, robustness of the closed loop against external disturbances is ensured. This result is also extended for mechanical systems interacting with elastic environments and linear deformation. The robust properties are preserved adding terms in the control law via the new change of coordinates.",

From these two parametrizations we derive the boundary port variables of the system and check the existence of solutions in the case of Dankwert boundary conditions. We show that existence of solution can be derived from both the coercivity condition on the closure relations and some inequality condition on the input matrix mapping. Even if in the case of constant parameters these two approaches are equivalent, the canonical factorization is the only one that can be applied when some of the parameters depends on the spatial variable. This property is of major interest when linearized non isothermal tubular reactors are considered.",

      "abstract": "The aim of this paper is to present a port-Hamiltonian (pH) formulation of the rigidbody attitude control problem, therefore enhancing the set of available tools for its modeling and control. First, a pH formulation of both dynamics and kinematics equations is presented. Second, a standard energy-balancing passivity-based controller (EB-PBC) is used for set-point tracking. Third, the controlled system is endowed with a dynamical extension to achieve set-point tracking without measuring the angular velocities. As a conclusive remark, it is showed under specific assumptions that these three results can be achieved regardless the coordinate representation in use. Additional examples follow to motivate the adoption of the pH formulation.",

This morphological computation can be modelled and designed using Port-Hamiltonian systems (PHS) theory, since the basis of both is the interconnection of dynamic elements. In this paper, we explore the application of PHS to morphological computation, showing that a three degrees-of-freedom elastic spring functioning as spine in a quadrupedal robot can lead to forward locomotion|without any complicated control action whatsoever.",

It is first shown in the 1D-wave equation case that the impedance matching boundary feedback can be written as a passive feedback on the boundary port variables. In the Euler-Bernoulli case, the impedance matching feedback matrix involves fractional derivatives and integrals. It is shown that the usual diffusive representation of such feedback is not formally a dissipative port-Hamiltonian system, even if from a frequency point of view this feedback proves passive.",

Based on the energetic integrator, the discrete-time methodology that exactly preserves the passivity property is presented for a linear Hamiltonian system with physical damping. A stability condition is given when taking the desired Hamiltonian as Lyapunov candidate function. The model of the spacecraft is composed of a rigid central body actuated by a torque motor around the vertical axis with two flexible appendages and a local mass at the tip of each appendage. Experiments are carried out to assess the validity of the more theoretical design methodology. The results show that the performances of our design results are better compared to an emulation controller obtained by sample and hold or Tustin transformation of the continuous-time controller.",

A structure-preserving discretization renders the partial differential equations ordinary ones. In this paper, we show how the structure of the lumped-parameter state representation for two conservation laws on a one-dimensional spatial domain can be exploited to easily formulate different (inverse) models. Based thereon, a simple modular procedure for feedforward controller design is developed, using known results from the dynamic inversion of nonminimum-phase systems. The example of the shallow water equations serves to illustrate the design steps and to present simulation results.",

In airplanes, for example, these coupled vibrations can lead to structural fatigue, noise and even instability. At ISAE, we have an experimental device that consists of a cantilevered plate with a fluid tank near the free tip. This device is being used for model validation and active control studies. This work uses the port-Hamiltonian systems formulation for modeling this experimental device. Structural dynamics and fluid dynamics are independently modeled as infinite-dimensional systems. The plate is approximated as a beam. Shallow water equations are used for representing the fluid in the moving tank. The global system is coupled and spatial discretization of the infinite-dimensional systems using mixed finite-element method allows to obtain a finite-dimensional system that is still Hamiltonian.",

This method combines two processes to reach both the second order accuracy and explicit computations. First, we design a one-step two- stage implicit numerical method for Port-Hamiltonian systems that preserves passivity. Second, a change of state is proposed to yield an explicit computation. It requires assumptions on the Hamiltonian variations. The complete method is illustrated on two basic examples for which these assumptions are fulfilled.",

Assume that on the edges there is no damping, and so the dynamics can be described by an infinite-dimensional, port-Hamiltonian system. For general infinite-dimensional systems, the zero dynamics can be difficult to characterize and are sometimes ill-posed. However, for this class of systems the zero dynamics are shown to be well-defined. Using the underlying structure, simple characterizations and a constructive procedure can be obtained.",

      "abstract": "This paper deals with the port Hamiltonian formulation of a 2D boundary controlled acoustic system. The system under consideration consits of an acoustic wave traveling in a tube equipped with a network of microphones/loudspeakers. The purpose of this smart skin is to damp the acoustic wave and reduce its effect at the output of the tube. It is first commented how the original 3D system can be reduced to a 2D system by considering symmetries. Then, the boundary port variables associated with the wave equation are parametrized in order to define a Dirac structure in two dimensions, compatible with the interconnection at the boundaries with the actuation system. The overall system (wave+actuators/sensors) is finally expressed as a port Hamiltonian control system and a first stabilizing distributed control law is proposed.",

      "abstract": "In this paper we consider partial differential equations in a port-Hamiltonian setting. A crucial property of this system class, especially for control purposes, is the property to be able to link a power balance relation to the structure of the equations. However, to derive this power balance relation one has to take into account also the effects of energy flows via the boundary. This can be handled in a straightforward manner when the Hamiltonian depends on derivative variables of first order, e.g. by using integration by parts. If higher-order derivatives appear (higher-order field theory) then integration by parts cannot be used without due care, thus we suggest an approach by using the so-called Cartan-form. In this paper we concentrate on second-order theories in a port-Hamiltonian framework and we visualize the derivation of a power balance relation by using mechanical examples such as plates modeled as a first-order and as second-order field theory.",

      "abstract": "This paper presents a Hamiltonian model of marine vehicle dynamics in six degrees of freedom in both body-fixed and inertial momentum coordinates. The model in body-fixed coordinates presents a particular structure of the mass matrix that allows the adaptation and application of passivity-based control interconnection and damping assignment design methodologies developed for robust stabilisation of mechanical systems in terms of generalised coordinates. As an example of application, we follow this methodology to design a passivity-based tracking controller with integral action for fully actuated vehicles in six degrees of freedom. We also describe a momentum transformation that allows an alternative model representation that resembles general port-Hamiltonian mechanical systems with a coordinate dependent mass matrix. This can be seen as an enabling step towards the adaptation of the theory of control of port-Hamiltonian systems developed in robotic manipulators and multi-body mechanical systems to the case of marine craft dynamics.",

Akin to the classical IDA-PBC method, the original system is transformed via a state-feedback to a port-Hamiltonian system where the corresponding interconnection and damping matrices and the energy function are shaped according to the given set of unsafe states and to the desired equilibrium point. By embedding it in a hybrid control framework, we show how the global results can also be obtained. We illustrate the efficacy of our proposed method on a nonlinear second-order system.",

Especially, heat exchangers of counter-flow type/parallel-flow type are treated, where they are respectively described by a coupled hyperbolic equations with time lag in the boundary feedback loop. When time lag does not exist, the exponential stability has been shown for counter-flow type by using the port Hamiltonian approach as well as the spectral analysis, and the conditions for the exponential stability to be assured are given. In this paper, time lag is expressed by using a transport equation, and the port Hamiltonian approach is applied to the whole system. A condition for the system with time lag to be exponentially stable is derived for counter-flow type and parallel-flow type.",

The method is applied to the Euler-Bernoulli equation with piezoelectric patches. The voltage is considered as an external input of the system. This gives rise to an unbounded input operator. A weak formulation is used to overcome this difficulty. It also allows defining a discretization method which leads to a finite-dimensional port-Hamiltonian system; the energy flow of the original system is preserved. Numerical results are compared to experimental ones to validate the method. Further work should use this model to couple the approximated equations with a more complex system, and to design active control laws.",

In this paper, an undamped wave equation system is given in the port-Hamiltonian formulation. The important issue of obtaining discrete version of the port-Hamiltonian system representation is explored. The exact discretization method is applied to the port-Hamiltonian system which transforms the system from a continuous to a discrete state space setting. The development of the discretized port Hamiltonian system formulation is necessary foundation for the discrete and computer based regulator and model realizations. The results are illustrated by numerical simulations.",

We show that a flexible-joint robot has a port-Hamiltonian representation which is also a singularly perturbed ordinary differential equation. Moreover, the associated reduced slow subsystem corresponds to a port-Hamiltonian model of a rigid-joint robot. To exploit the usefulness of the reduced models, we provide a numerical example where an existing controller for a rigid robot is implemented.",

      "abstract": "Energy based approaches have proven to be specially well suited for the modeling and control of mechanical systems. Among these approaches the port-Hamiltonian framework presents interesting properties for the structural modeling of complex systems and for the design of non-linear controllers using passivity In this paper we use this framework to model a typical micro-robotic contact scenario and to propose a simple but effective globally stabilizing controller. The model and the controller take into account the transitions from a non-contact to a contact state (and the inverse) by the introduction of a non-linear (switching) contact element. A one degree of freedom experimental micro-robotic setup is used to test and illustrate the results.",

The Chaplygin sleigh cannot be asymptotically stabilised with a smooth control law, since Brockett’s necessary conditions for smooth stabilisation is not satisfied. To asymptotically stabilise the origin, two potential energy shaping control laws are developed that render the system asymptotically stable to two equilibrium manifolds, which intersect at the origin. A switching strategy between the energy shaping controllers is derived that ensures the system converges to the intersection of the equilibrium manifolds.",

We derive conditions under which the power system admits a steady-state behavior characterized by an operation of the grid at a synchronous frequency as well as a power balance for each single device. Based on this, we specify a set on which the dynamics of the power grid match the desired steady-state behavior and show that this set is control-invariant if and only if the control inputs to the generators are constant. Moreover, we constructively obtain network balance equations typically encountered in power flow analysis and subsequently show that the power system can be operated at the desired steady-state if and only if the network balance equations can be solved.",

Virtual couplings define interaction control forces between neighbouring vehicles. Moreover, the couplings are designed to enforce a desired vehicle-vehicle and vehicle-target spacing. The whole network is modelled in the passive, energy-based, port-Hamiltonian framework. Such framework allows to prove closed-loop stability using the whole system kinetic and virtual potential energy by constructing a suitable Lyapunov function. Furthermore, the robustness to communication delays is also demonstrated. Simulation results are given to illustrate the effectiveness of the proposed approach.",

The structure of the system is derived from the expression of the internal entropy creation, and just as for the lumped case the IPHS structure is expressed as a function of the distributed thermodynamic driving forces and a positive definite function containing the thermodynamic parameters of the different diffusion processes. The distributed thermodynamic driving forces are expressed as the evaluation of the internal energy density and entropy density on a pseudo-Poisson bracket defined by the skew-adjoint differential operator defining the coupling between the different energy domains. This is analogous to the case of lumped IPHS, where the pseudo-Poisson bracket is defined not by differential operators but by constant (canonical) skew-symmetric matrices.",

Two classes of observers preserving the port-Hamiltonian structure are considered: a proportional observer; and a proportional observer with an integral action. It is shown that the proposed passive observers are stable with respect to the interconnection of the observed system and the observer. For both designs, the observation gains are chosen such that the error dynamics takes the form of a port-Hamiltonian system. Simulation results for plasma profiles estimation illustrate the proposed observers performance, including in cases where their key physical parameters are badly known.",

The closed-loop system is in IPHS form, hence it can be identified with a desired reaction network and the control parameters are related with thermodynamic variables, such as the reaction rates. A complex reaction network is used to illustrate the approach: the van der Vusse reaction mechanism.",

We propose distributed controllers that regulate the pressure drop at each end-user asymptotically towards desired set-points. We prove that the obtained closed-loop nonlinear system is locally asymptotically stable. In contrast to previous results, the proposed solution guarantees besides pressure regulation, that the pumps generate only positive pressures (inputs), required by many (centrifugal) pumps that are commonly used in hydraulic networks.",

Then, using a Control by Interconnection (CbI) approach, a distributed state feedback is designed in order to transform an hyperbolic PHS into a parabolic one, the latter being asymptotically stable and even purely dissipative (with no oscillating modes). Distributed wave damping in 1D vibro-acoustic pipes, using piezo actuators, is considered as an illustration example for the proposed control design.",

The result is applied on a non-linear model of an ideal, compressible, isentropic fluid with one-dimensional spatial domain. The idea is to design at first a state feedback law able to perform the energy-shaping task, i.e. able to render the closed-loop system a port-Hamiltonian system with a new Hamiltonian with a minimum at the desired equilibrium. Then, under some assumptions on the existence of solutions and pre-compactness of trajectories, asymptotic stability is obtained via damping injection on the boundary. The result is a consequence of the La Salles Invariance Principle in infinite dimensions.",

For the physical power grid a third-order structure-preserving model is considered involving both frequency and voltage dynamics. By applying the primal-dual gradient method to the social welfare problem, a distributed dynamic pricing algorithm in port-Hamiltonian form is obtained. After interconnection with the physical system a closed-loop port-Hamiltonian system of differential-algebraic equations is obtained, whose properties are exploited to prove local asymptotic stability of the optimal point.",

      "abstract": "The power grid evolution towards the smart grid integration is certainly expected in the near future. Disciplinary technologies from many fields that are combined for such a large scale venture, have a complicated result. It seems that rather more efficient tools are needed for the analysis and design of the future smart electric grids, especially at the distribution part. A possible solution is the complex network deployment that provides an alternative framework to better understand and analyze smart grid systems that are composed by different interacting parts in a network fashion. The complex network representation can thus be extended to a multi-level formulation where at any level the outputs may be used as command inputs for the lower levels. The method is established on the basis of suitably determined graphs and therefore can be used in a common way, independently from variations on grid topology or the power injected or consumed. This is a very valuable fact due to the intermittent and unpredictable nature of modern distribution systems. However, a basic problem that arise is how under any possible graph representation, one can be sure that the system is undoubtedly stable. Therefore, in this paper, a systematic method, absolutely compatible with the complex network deployment, is established to indicate that, under common conditions, every modern distributed generation system with variable topology and bounded control inputs, can be represented as a special structure passive port-Hamiltonian stable system. Finally, a particular microgrid example with a standard primary control level scheme is examined to evaluate the proposed method.",

The tracking problem is solved by defining a suitable invariant sliding manifold which provides a desired steady state behavior. The manifold is then made attractive via contraction techniques. Finally, we present numerical simulation results where a SCARA robot is commanded by the proposed tracking control law.",

      "abstract": "Whereas conventional power systems heavily rely on bulk generation by synchronous machines, future power systems will be comprised of distributed generation based on renewable sources interfaced by power electronics. A direct consequence of retiring synchronous generators is the loss of rotational inertia, which thus far was the dominant time constant in a power system, as well as the loss of the generator controls, which are the main source of actuation of the power grid. Prompted by these paradigm shifts, we study the dynamic behavior of a nonlinear and first-principle low-inertia power system model including detailed power converter models and their interactions with the power grid. In this paper, we focus particularly on the admissible steady-state behavior of such a low-inertia power grid and derive necessary and sufficient control specifications for power converters.",

      "abstract": "This paper presents a modular modeling framework for the Ocean Grazer’s Power Take-Off (PTO) system, which operates as an array of point-absorber type devices connected to a hydraulic system. The modeling is based on the port-Hamiltonian (PH) framework that enables energy-based analysis and control of the PTO system. Firstly, a modular model of a point-absorber hydraulic system, which represents the main building block of the PTO, is presented. The model consists of wave-mechanical and hydraulic subsystems that are interconnected with a transformer-type interconnection. Secondly, we show passivity of the point-absorber hydraulic element and the accumulation of potential energy, which is due to the novel pumping mechanism of the point-absorber. Finally, we illustrate these properties through simulation results.",

      "abstract": "In this paper, we adopt eigenstructure assignment in order to assist with the tuning of a nonlinear energy-based regulator for the positioning of a marine craft in the horizontal plane. The control law is designed using interconnection and damping assignment passivity-based control (IDA-PBC), which results in passive target dynamics that can be expressed as a port-Hamiltonian system (PHS). IDA-PBC has been applied before with success in a number of different applications. To date, however, there has been minimal development in either tuning tools or techniques that can analytically aid the designer in achieving the desired response characteristics. Good results can be achieved only with intuitive and meticulous manual tuning. By linearising the nonlinear target dynamics in PHS form, we demonstrate that the analysis of the eigenstructure, and consequently its assignment can significantly aid the tuning process. The approach provides a mechanism for simultaneously considering the frequency domain characteristics at a point of linearisation, as well as the time domain characteristics. A demonstration of the method is provided in the form of a design study for position regulation of an underwater vehicle in the horizontal plane.",

The originality lies in the fact that all design steps, from modeling, over discretization to feedforward control are executed within the port-Hamiltonian (PH) framework. To obtain a finite-dimensional PH model which is suitable for inversion-based feedforward control design, a geometric pseudo-spectral discretization is performed. The feedforward control is tested with a plant model implemented in standard FEM software. The results of this paper will be amended by feedback control to achieve highly dynamic motion control on a lab test rig which is currently under construction.",

      "abstract": "This paper deals with the structure and passivity preserving model reduction and the reduced order controller design for a class of distributed controlled port Hamiltonian systems - Timoshenko beam. The boundary conditions of the beam lead to physical constraints which are hardly considered in the reduction procedure. In this work we propose to use the descriptor system realization of port Hamiltonian system to conserve the physical constraints. A passive LQG control design method is proposed for this type of system. This LQG method defines a balanced coordinate which allows us to reduce the system. Using the obtained reduced model, a reduced order passive controller which stabilizes the full order system is designed using the LQG method. At last we give the numerical simulations to show the effectiveness of the proposed reduced passive controller.",

The model relates electrical and mechanical inputs to corresponding conjugate outputs, allowing to simulate the membrane transducer in actuation and energy harvesting application. Starting from a nonlinear, physics-based model developed in the authors’ previous works, a suitable function is initially proposed to quantify the overall electro-mechanical energy in the system. Subsequently, a complete description in terms of Hamiltonian, dissipation function, and system matrices is provided. The port-Hamiltonian formalism permits to assess the thermodynamic consistency of the model, making it a reliable tool for the prediction of energetic performance in dynamic applications. Furthermore, it opens up the possibility of applying powerful nonlinear analysis and design tools.",

      "abstract": "Multi-carrier energy systems have been identified as a major concept for future energy supply. For their operation, model-based control methods are necessary whose design requires modular, multi-physical control-oriented models. In literature, there exists no control design model which combines the variables of the networks and system dynamics that go beyond ideal storage elements. Port-Hamiltonian systems represent a promising approach for the scalable modeling and control of multi-carrier energy systems. In this publication we present a case study which illustrates the port-Hamiltonian modeling of an exemplary coupled electricity and gas distribution system. Simulations indicate the plausibility of the presented model.",

      "abstract": "This paper presents the dynamical model of a DC microgrid, composed by a solar panel, an energy storage system, a utility grid and a group of interconnected loads, such as housing-office equipment and electrical vehicles. The transmission lines connect the energy sources with the loads through the corresponding switching DC/DC converters. The novelty resides in the port-Hamiltonian formulations developed for the physical model which is first described through a Bond Graph. An extended architecture of the system with a meshed topology is presented. The proposed architecture has the ability to reduce the power losses within the DC microgrid system by increasing the different transmission line paths among the sources and the loads. The global dynamical model of the system is finally converted into a state-space representation. Furthermore, in view of system control and optimization we formulate the load balancing problem of the DC microgrid in order to stabilize the power flow within the DC bus. The model is validated with some primary simulations.",

Such a model represents an effective control-oriented tool to describe the hysteretic dynamics of SMAs, but its highly complex structure makes it difficult to analyze fundamental properties such as energetic consistency, i.e., passivity. Focusing on the isothermal case, we propose a suitable storage function which permits to analyze passivity of the SMA model and to quantify energy dissipation due to hysteresis. In addition, a port-Hamiltonian representation of the resulting passive model is developed. This result permits to quantitatively assess energetic performance of SMAs when operating, e.g., as passive non-viscous dampers, and opens up the possibility of using powerful tools from port-Hamiltonian theory to analyze and design control systems for SMA actuators.",

By representing the hysterisis through hysterons interconnected with the mechanical and electrical components, it is shown that the hysteresis behaves as an irreversible process. This is elegantly captured by the IPHS structure and makes it possible to isolate the different irreversible phenomena of the overall system. Furthermore, it is shown that in general an electromechanical system with hysteresis corresponds to a reversible-IPHS, i.e., the combination of a conservative Hamiltonian system with an irreversible one defined with respect to the same Hamiltonian. A micro-mechatronic example is used to illustrate the approach.",

The variational formulation is based on the introduction of the concept of thermodynamic displacement. This concept makes possible the definition of a nonlinear nonholonomic constraint given by the expression of the entropy production associated to the irreversible processes involved, to which is naturally associated a variational constraint to be used in the variational formulation. We consider both discrete (i.e., finite dimensional) and continuum systems and illustrate the variational formulation with the example of the piston problem and the heat conducting viscous fluid.",

The Dirac structures are constructed on the Pontryagin bundle P = TQ ⊕ T ⁎ Q, where Q = Q × ℝ is the thermodynamic configuration manifold. In particular, it is illustrated how one can develop Dirac structures that include nonlinear nonholonomic constraints originated from the entropy production in each irreversible process. Lastly, we also present the induced Dirac structure on N = T⁎Q × ℝ together with the associated Lagrange-Dirac and Hamilton-Dirac dynamical formulations in analogy with nonholonomic mechanics.",

      "abstract": "Electrochemical processes play an important role in many natural and technological processes; such as, mineral refining, water purification, energy storage and generation. The port-Hamiltonian framework has been widely used for modeling and control design of mechanical and electro-mechanical systems. It has demonstrated to be an important tool to analyze and integrate models of different domains. This work discusses the modeling of isothermal electrochemical processes as port-Hamiltonian systems. Port-Hamiltonian models based on the Gibbs energy function are derived for two examples. They illustrate the main steps to obtain a port-Hamiltonian representation from molar and charge balance equations. Further work will consider non isothermal reactions and the analysis of system considering also diffusion phenomena.",

The energy representation of one heat exchanger is presented based on the incidence matrices of the graph related to heat transfer and the graph of the heat convection. Then the global heat exchanger network is obtained from the heat exchanger graph models as well as the incidence matrices of the interconnection obtained by adding additional vertices corresponding to the connector elements. The Port Hamiltonian representation of the heat network exchanger is given in the case of constant pressure. Then we show the incremental passivity of one compartment of the heat exchanger.",

      "abstract": "Fluid-structure interaction models are of special interest for studying the energy transfer between the moving fluid and the mechanical structure in contact. The vocal folds are an example of a fluid-structure system, where the mechanical structure is usually modeled as a mass-spring-damper system. In particular, the estimation of the collision forces of the vocal folds is of high interest in the diagnosis of phonotraumatic voice pathologies. In this context, the port-Hamiltonian modeling framework focuses on the energy flux in the model and the interacting forces. In this paper, we develop a port-Hamiltonian fluid-structure interaction model based on the interconnection methodology proposed by Lopes and Hélie (2016).",

      "abstract": "In this contribution, we develop a structured port-Hamiltonian model for a class of irreversible distributed parameter systems and exploit the obtained formulation for model reduction from dimension 3 to dimension 1 in space. The proposed methodology is motivated by the control of burning plasma profiles in Tokamak reactors. The burning plasma is viewed as a multi-physics system built on Maxwell equations and total mass, species, momentum, energies, and entropy balance equations. Moreover, the system presents nonlinear couplings, especially through transport coefficients, and its dynamic evolves over multiple time scales. The main couplings considered here are the Joule effect, the Lorentz forces, and the fusion reaction kinetics. The port-based modeling formulation and reduction rely on the use of the Gibbs relation, Onsager linear transport theory, Stokes–Dirac structures, and energy preserving geometric reduction.",

      "abstract": "A number of applications involving wave propagation are asymptotically stable, but the decay rate of the mode does not increase with increasing wave number. Applications include electrical transmission, acoustic waves and water waves. There are many different approximation methods for these systems that are fine for simulation. But the qualitative behaviour of the approximated eigenvalues can be quite different. Controller and estimator design with different approximations can yield different results. A number of partial differential equations (PDEs) are derived using Hamilton’s principle. This provides information about the energy of the system that can be a guideline in establishing well-posedness on an appropriate state space. Recent work on a port-Hamiltonian approach to approximation shows promise in obtaining finite-dimensional approximations that are useful for control and estimation. A key feature of the port-Hamiltonian approach is careful attention to how the energy in the system is modelled and approximated. How does this approach compare to more traditional approaches to scientific computation? In particular, what are the similarities and what are the differences? These questions will be examined in the talk, and in discussion, through several relatively simple examples.",

      "abstract": "Repetitive Control (RC) schemes are described by systems of coupled PDEs and ODEs and, in this paper, their stability analysis relies on the modularity of the port-Hamiltonian framework to characterise a family of linear plants for which this control technique can be successfully applied. To achieve this, the regulator, that is in fact an infinite dimensional system, is treated as a boundary control system in port-Hamiltonian form, and novel results dealing with the exponential stabilisation of this class of infinite dimensional systems are exploited. The focus here is on plants that are strictly proper and, as a consequence, on Modified Repetitive Control (MRC) schemes, i.e. RC schemes in which a low-pass filter is in series with the pure delay block. The result is a characterisation of a class of linear systems for which MRC schemes converge.",

      "abstract": "In this paper, the mathematical model of a flexible spacecraft system composed of a hub and two symmetrical beams loaded with tip masses is reconsidered to design a control law for internal disturbance rejection. This model has a port-Hamiltonian structure and is passive. The disturbance rejection is performed by a feedback control law using the angular rates at the two tips of a beam. The closed-loop asymptotic stability of such a collocated / non-collocated control is analyzed through explicitly solving the Partial Differential Equations (PDE) of the system. Finally, the experimental results are carried out to assess the validity of the proposed control methodology.",

Moreover, since boundary control and observation appear naturally in this formulation, the method is suitable both for simulation and control of infinite-dimensional port-Hamiltonian systems. The method can be applied using FEM software, and comes along with worked-out test cases on the 2D wave equation in different geometries and coordinate systems.",

For systems with non-zero input, symplecticity extends to the conservation of a discrete energy balance, based on which a discrete-time Dirac structure is defined. Using Gauss-Legendre collocation, the corresponding quadrature formula allows to quantify the discretization error for the supplied energy. On a linear example, backward error analysis and numerical experiments are performed in order to illustrate the accuracy of the resulting structure-preserving integration schemes.",

The existing pHs discretization methods deal only with the geometric part, in this paper we perform an adapted symplectic time stepping to get the fully discrete scheme in order to preserve both the geometrical properties and the energy aspects. We also show that staggered finite volume method carry over to a non-linear problem, the 2D irrotational shallow water equations. However, due to the non linearity and the non separability of the Hamiltonian, some difficulties arise both for the high order accuracy in the spatial discretization, and also for the symplecticity of the time integration.",

This allows us to directly interconnect the wave-structure pH model with an existing pH model of (an array of) wave energy converters (WEC)s, thereby enabling the application of existing pH-based control and optimization methods to the interconnected WEC. We present a Hamiltonian function corresponding to the radiation terms, based on which a pH model of radiation forces is constructed. Lastly, using a simple array of floaters, where each one is connected to a linear power take-off (PTO) system, we compare the simulation of our pH model with the results of the standard open-source toolbox WEC-Sim, which is designed for simulating any type of WEC.",

Moreover we consider changes in the cable parameters, i.e. it’s elasticity, mass and length when the cables are wound/unwound from the winches. To the best of our knowledge nobody considered such a detailed and generic model of a CDPR in PH structure before. Since motion simulators are built to mimic systems with different physical properties, PH modeling can pave the way for physics-shaping controllers.",

This is a constructive design method that combines the concept of virtual systems and of differential passivity. We apply the method to the tracking control problem of flexible joints robots (FJRs) which are formulated in the port-Hamiltonian (pH) framework. Simulations on a two degrees of freedom FJR are presented to show the performance of a controller obtained with this approach.",

Using a general parameterization of the passive outputs for pH systems, we give necessary conditions to construct PID-PBCs and carry-out the stability analysis of the desired equilibrium point in closed-loop. The main results are the inclusion of additional degrees of freedom for the solution of the partial differential equation that is necessary to complete the controller design and the novel construction of PID-PBCs using passive outputs with relative degree zero.",

In this paper, we propose a method to robustify a system which has been stabilised using IDA-PBC with respect to constant, matched disturbances via the addition of integral action. The proposed controller extends previous work on the topic by being robust against uncertainty in the damping structure of the system, a quantity which may not be known in many applications.",

The inner tube of the endoscope is a flexible structure that can be represented by a Timoshenko beam. Actuators are patches of EAP. There is freedom in the choice of EAP actuators location. In this paper, we first propose a port Hamiltonian model of the endoscope. In order to choose the optimal location for the EAP actuators, we consider the linear quadratic (LQ) performance as the optimal performance objective. At last, some numerical simulation results are given based on the real experimental setup parameters.",

It is first investigated how a given optimal control affect the closed-loop system design and, on the other hand, how an optimal criterion may be used as a guideline for IDA-PBC parameters design. The case of a trivial relation between the optimal control gain and the desired total power in the IDA-PBC design is investigated in this work while some other choices could be further considered. The proposed method is successfully illustrated via the example of a linearized pendulum.",

It is well known that nonholonomic mechanical systems cannot be asymptotically stabilised using smooth control laws as they do no satisfy Brockett’s necessary condition for smooth stabilisation. Here, we propose a discontinuous control law that can be interpreted as a potential energy shaping and damping injection controller. The proposed controller is shown to be robust against the parameters of both the inertia matrix and the damping structure of the open-loop system.",

      "abstract": "A simple lumped port-Hamiltonian model for an actuated flexible beam is proposed. The flexible beam is modelled as a n-DOF actuated beam, and the port-Hamiltonian model is constructed by a systematic interconnection of the links of the beam. The proposed model is then instrumental to derive a stabilizing controller using interconnection and damping assignment - passivity based control considering an underactuated scenario. The work has been developed motivated by the practical application to a medical endoscope with distributed actuation by electro-active polymers. The lumped parameter model offers the possibility of having input/output ports in every joint between successive links, this permits to easily model the action of the actuators as an input force applied to a specific joint.",

      "abstract": "This work proposes a passivity-based approach to deal with the output-tracking-error problem for a large class of nonlinear chemical processes including non-minimum phase systems. More precisely, in that framework, the system dynamics is firstly written into the relaxing (pseudo) port-Hamiltonian representation which does not necessarily require the positive semi-definite property of the damping matrix. Then, a reference trajectory associated with a certain structure passing through a desired equilibrium point (i.e., the set-point) is chosen so that the error dynamics can be globally asymptotically stabilized at the origin thanks to the assignment of an appropriate damping injection. This method is subsequently illustrated for a benchmark of multiple reactions systems, namely Van de Vusse reaction system. The numerical simulations show the applications of the proposed approach.",

Its dynamical analysis is described through the Bond Graph notion and the port-Hamiltonian formalism. A multiscale supervision scheduling is developed to handle the load balancing problem for the proper energy distribution within the transmission network. The control architecture considers three control layers. These are implemented via a combination of differential flatness and MPC (Model Predictive Conctrol).",

      "abstract": "Electrochemical processes have been developed for a wide range of applications such as, mineral refining, water purification, energy storage and generation. The development of models to describe these processes is very important for their analysis, optimization and operation. The framework of irreversible port-Hamiltonian systems has proven to be an important tool to analyze and integrate thermal models with models of different domains. This work discusses the modeling of non-isothermal electrochemical processes as irreversible port-Hamiltonian systems. An irreversible port-Hamiltonian model based on the internal energy function is derived for a simple but general example. The irreversible model is obtained from the molar and charge balance equations combined with the entropy balance equation. The resulting model can be interpreted as a thermodynamic system and aspects such as entropy production, thermodynamic driving forces and intensive/extensive variables are encoded in the representation. An electrochemical process with two simultaneous reactions is considered to illustrate the approach. The interconnection with a resistive load is also considered to illustrate the benefit of the port-based formulation of the model.",

      "abstract": "The aim of this paper is to recast the heat equation with boundary control and observation in the port-Hamiltonian formalism. The anisotropic and heteregenous case in an n-D geometrical domain is systematically developped. Three different points of view are presented. The first two are thermodynamically founded, taking either entropy or energy as Hamiltonian functional. With the choice of entropy, the second principle can be recovered. With the choice of energy, following Zhou et al. (2017), extra physical variables are introduced allowing to recover the first principle. The third formulation is classical from a mathematical perspective, although less meaningful physically speaking; however the Hamiltonian proves to be a Lyapunov functional, which is useful for boundary control purposes. Moreover, all these three formulations can be discretized with a structure-preserving scheme, as presented in the companion paper Serhani et al. (2019a).",

      "abstract": "The heat equation with boundary control and observation can be described by means of three different Hamiltonians, the internal energy, the entropy, or a classical Lyapunov functional, as shown in the companion paper (Serhani et al. (2019a)). The aim of this work is to apply the partitioned finite element method (PFEM) proposed in Cardoso-Ribeiro et al. (2018) to the three associated port-Hamiltonian systems. Differential Algebraic Equations are obtained. The strategy proves very efficient to mimic the continuous Stokes-Dirac structure at the discrete level, and especially preserving the associated power balance. Anisotropic and heterogeneous 2D simulations are finally performed on the Lyapunov formulation to provide numerical evidence that this strategy proves very efficient for the accurate simulation of a boundary controlled and observed infinite-dimensional system.",

More precisely, a linear transformation is used to transform the original dynamics into a new model, where the enthalpy, reaction variant and reaction invariant are the state variables. Then, the transformed model is formulated into the port-Hamiltonian structure before the tracking-error-based approach is applied to design the controllers for the purpose of stabilization. The numerical simulations for the first order reaction modelled with the continuous stirred tank reactor having the multiplicity behavior subsequently show that the proposed feedback law is able to stabilize the system at the desirable equilibrium point.",

More specifically, a parametrised version of the repetitive compensator, i.e. of the infinite-dimensional controller employed in RC schemes, modelled as a boundary control system (BCS) in port-Hamiltonian form is presented. Well-posedness and stability of such control scheme are rigorously addressed thanks to novel tools based on dissipativity theory and originally developed for the stabilisation of BCS. Here, the linear and the nonlinear cases are tackled, and in both the cases the classes of plants for which RC schemes are exponentially stable are determined. Moreover, and explicit motivation of perfect asymptotic tracking and disturbance rejection for exponentially stable RC systems without relying on the internal model theory is provided. To show the validity of the analysis, simulations are reported.",

This is the main difference with respect to the port-Hamiltonian form, where the dynamic depends on the derivatives up to a certain order and with respect to the spatial coordinate of the gradient of the Hamiltonian function, i.e. of the total energy.",

      "abstract": "The port-Hamiltonian framework allows for a structured representation and interconnection of distributed parameter systems described by Partial Differential Equations (PDE) from different realms. Here, the Mindlin-Reissner model of a thick plate is presented in a tensorial formulation. Taking into account collocated boundary control and observation gives rise to an infinite-dimensional port-Hamiltonian system (pHs). The Partitioned Finite Element Method (PFEM), already presented in our previous work, allows obtaining a structure-preserving finite-dimensional port-Hamiltonian system, and accounting for boundary control in a straightforward manner. In order to illustrate the flexibility of PFEM, both types of boundary controls can be dealt with: either through forces and momenta, or through kinematic variables. The discrete model is easily implementable by using the FEniCS platform. Computation of eigenfrequencies and vibration modes, together with time-domain simulation results demonstrate the consistency of the proposed approach.",

      "abstract": "A 2D wave equation with boundary damping of impedance type can be recast into an infinite-dimensional port-Hamiltonian system (pHs) with an appropriate feedback law, where the structure operator J is formally skew-symmetric. It is known that the underlying semigroup proves dissipative, even though no dissipation operator R is to be found in the pHs model. The Partitioned Finite Element Method (PFEM) introduced in Cardoso-Ribeiro et al. (2018), is structure-preserving and provides a natural way to discretize such systems. It gives rise to a non null symmetric matrix R. Moreover, since this matrix accounts for boundary damping, its rank is very low: only the basis functions at the boundary have an influence. Lastly, this matrix can be factorized out when considering the boundary condition as a feedback law for the pHs, involving the impedance parameter. Note that pHs - as open system - is used here as a tool to accurately discretize the wave equation with boundary damping as a closed system. In the worked-out numerical examples in 2D, the isotropic and homogeneous case is presented and the influence of the impedance is assessed; then, an anisotropic and heterogeneous wave equation with space-varying impedance at the boundary is investigated.",

Departing from the partial differential equations that describe mass and momentum balances a scalable lumped-parameter model is proposed. To this end the framework of port-Hamiltonian systems is instrumental to derive a modular system which upon interconnection describes segments with different cross sections and dissipation effects. In order to perform the interconnection between different segments the incompressibility hypothesis is relaxed in some infinitesimal section to admit density variations and energy transference between segments. Numerical simulations are performed in order to illustrate the model.",

The mechanical dynamic of the flexible beam and the electrical dynamic of the IPMC actuators have been taken into account in the modeling approach. Furthermore, in order to achieve the desired configuration of this IPMC actuated flexible beam, a control strategy is proposed based on the Linear quadratic Gaussian (LQG) control and damping injection. Finally, the proposed model is validated on a real experimental set-up. The effectiveness of the proposed control strategy is shown by the simulation results based on the real physical parameters of the experimental set-up.",

      "abstract": "This paper aims to propose a finite-dimensional observer-based state feedback controller to stabilize a class of boundary controlled system. To this end, we propose to use an early-lumping approach, where the infinite-dimensional port-Hamiltonian system is first discretized using a structure-preserving method. Then, we build a passive observed-based controller using a Linear Matrix Inequality (LMI) and finally, the controller is interconnected with the infinite-dimensional system in a passive way. Due to its passivity and Hamiltonian structure, this observer-based controller can stabilize not only the discretized lumped parameter system but also the original distributed parameter system. This approach avoids the intrinsic drawback of early lumping approach and spillover effects. Finally, the boundary controlled undamped wave equation is used to illustrate the effectiveness of the proposed controller.",

The systems under consideration, governed by partial differential equations, are described in a port-Hamiltonian setting making heavy use of the underlying jet-bundle structure, where we restrict ourselves to systems with 1-dimensional spatial domain and 2nd-order Hamiltonian. To show the applicability of the proposed approach, we develop a dynamic controller for an Euler-Bernoulli beam actuated with a pair of piezoelectric patches and conclude the article with simulation results.",

This model describes the multiscale structure of the system. Submodels are coupled by boundary multi-scale elements. In order to preserve the causality of the system, Lagrangian multipliers are introduced to deal with the coupling between the electro-stress diffusion in the polymer and the flexible beam structure of the actuator. Finally, a structure-preserving discretization scheme and some appropriate projections are used to derive an explicit model suitable for simulation. The accuracy of the model is verified using experimental data.",

Combining the spatial with a structure-preserving temporal scheme leads to a fully discretized control model of the infinite-dimensional system, which can be exploited for discrete-time trajectory planning. We show that with a suitable approximation of the continuous nonlinear equations, a stable explicit numerical scheme is obtained for flatness-based feedforward control of quasilinear hyperbolic systems. As an example, we consider the 1D shallow water equations and the inverse flow routing problem, i. e. the computation of the upstream discharge trajectory from a given downstream hydrograph. We compare our approach with known results based on the method of characteristics.",

A generalized canonical transformation connects two port-Hamiltonian systems through a pair of a feedback and a coordinate change. This paper clarifies how a generalized canonical transformation connects the plant nonholonomic port-Hamiltonian system with an error system. Stabilizing the path following error system allows one to derive a constructive path following control law for the nonholonomic port-Hamiltonian system. Finally, an example shows a concrete design procedure of the proposed method.",

These systems are Hamiltonian control systems defined on a symplectic manifold, however departing from standard Hamiltonian control systems, due to the property that the Hamiltonian function is homogeneous in the generalized momentum variables. In this paper we study the class of state feedbacks preserving the geometric structure of such Homogeneous Hamiltonian control systems and rendering the closed-loop system again a Homogeneous Hamiltonian control system. It is shown that only a constant control preserves the canonical Liouville form. Hence a non-trivial state feedback necessarily changes the geometric structure in closed-loop defined by a modified Pfaffian form. Finally we derive a matching equation on the nonlinear feedback and the closed-loop Pfaffian form.",

The operator matrix representation of the structure includes not only exterior differential operators, but also codifferential operators in the sense of the dual of the pairing between differential forms. Since the successive operation of the matrix is equivalent to the Laplace-Beltrami operator, we call it a Stokes-Dirac operator. Furthermore, the Stokes-Dirac operator is augmented by harmonic differential forms that reflect the topological geometry of manifolds. The extension enable us to describe a power balance of particular boundary energy flows on manifolds with a non-trivial shape.",

Based on this condition, we investigate classes of port-Hamiltonian and gradient systems which are Krasovskii’s passive. Moreover, we provide a new interconnection based control technique based on Krasovskii’s passivity. Our proposed control technique can be used even in the case when it is not clear how to construct the standard passivity based controller, which is demonstrated by examples of a Boost converter and a parallel RLC circuit.",

First a port-Hamiltonian formulation for a countercurrent heat exchanger is proposed. It is so as to guarantee convergence of the observer. It is shown that the Stokes-Dirac structure obtained by opening only the dissipation ports due to the convection phenomenon, is conservative. Secondly, a SMO based on an interconnected structure of port-Hamiltonian systems is designed. The convergence of the dynamics of the estimation error is proven. The simulation results illustrate the effectiveness of this estimation strategy.",

      "abstract": "With the gradual transformation of power generation towards renewables, distributed energy resources are becoming more and more relevant for grid stabilization. In order to involve all participants in the joint solution of this challenging task, we propose a distributed, model-based and unifying controller for frequency and voltage regulation in AC microgrids, based on steady-state optimal control. It not only unifies frequency and voltage control, but also incorporates the classic hierarchy of primary, secondary and tertiary control layers with each closed-loop equilibrium being a minimizer of a user-defined cost function. By considering the individual voltage limits as additional constraints in the corresponding optimization problem, no superordinate specification of voltage setpoints is required. Since the dynamic model of the microgrid has a port-Hamiltonian structure, stability of the overall system can be assessed using shifted passivity properties. Furthermore, we demonstrate the effectiveness of the controller and its robustness against fluctuations in active and reactive power demand by means of numerical examples.",

      "abstract": "This paper presents an observer based nonlinear control for a flexible beam clamped on a rotating inertia. The considered model is composed by a set of Partial Differential Equations (PDEs) interconnected with an Ordinary Differential Equation (ODE), with control input in the ODE. The control problem consists in orienting the beam at the desired position, maintaining the flexible vibrations as low as possible. To this end, it is presented a nonlinear controller that depends on the beam’s state. An Observer is designed to reconstruct the infinite dimensional state, and the estimated state is used in the nonlinear controller instead of the real one. Assuming well-posedness of the closed loop system, it is shown the exponential convergence of the estimated state, and the asymptotic stability of the closed loop system. Numerical simulations are presented to characterize the closed loop behaviour with different choices of observer’s parameters.",

A finite element based method is employed to obtain a consistently discretized model.

The two approaches are assessed numerically, by comparing the Hamiltonian and the state variables norm for progressively refined meshes.",

For this purpose, we suggest to use the phase field modeling approach. In the first part we recall the phase field models, in particular the Cahn–Hilliard and Allen–Cahn equations, and show that they may be expressed in terms of a dissipative Hamiltonian system. In the second part we show how this Hamiltonian model may be extended to a Boundary Port Hamiltonian System and illustrate the construction on the example of crystallization.",

      "abstract": "Metallic open cell foams have multiple applications in industry, e.g. as catalyst supports in chemical processes. Their regular or heterogeneous microscopic structure determines the macroscopic thermodynamic and chemical properties. We present an object-oriented python library that generates state space models for simulation and control from the microscopic foam data, which can be imported from the image processing tool iMorph. The foam topology and the 3D geometric data are the basis for discrete modeling of the balance laws using the cell method. While the material structure imposes a primal chain complex to define discrete thermodynamic driving forces, the internal energy balance is evaluated on a second chain complex, which is constructed by topological duality. The heat exchange between the solid and the fluid phase is described based on the available surface data. We illustrate in detail the construction of the dual chain complexes, and we show how the structured discrete model directly maps to the software objects of the python code. As a test case, we present simulation results for a foam with a Kelvin cell structure, and compare them to a surrogate finite element model with homogeneous parameters.",

The goal is to achieve open-loop output tracking or finite-time transitions between steady states or operating profiles. Introducing new (fictious) boundary conditions in terms of so-called flat outputs, the port-Hamiltonian system is reformulated as a Cauchy problem in the spatial domain. The parametrization of any system variable and input by the flat output is computed using two different solution approaches. By assigning a suitable desired trajectory for the flat output, the input parametrization yields the feed forward control law to solve the motion planning task. The presented theory is applied to the wave equation with spatially varying parameters and is evaluated by numerical calculations and simulations.",

In this paper, we extend the definition of Port Hamiltonian systems defined with respect to Lagrangian submanifold to a class of infinite-dimensional systems where the Lagrangian submanifold is defined by first-order differential operators. We show that this adds some port boundary variables and derive the energy balance equation. This construction is illustrated on the model of a flexible nanorod made of composite material.",

The control action, implemented through a state feedback or a dynamic controller, is derived by using the port-Hamiltonian framework. More precisely, the standard energy-shaping approach plus damping assignment is adapted to cope with infinite dimensional systems with anti-damping boundary conditions. It is shown how to modify the equivalent dynamic controller to account for the instability propagation along the domain.",

We develop a method of bicomplex pH systems that is strictly symplectic and we show how it overcomes the obstacle and allows one to systematically use Casimir functions to shape the energy.",

It is well-known that explicit PHSs can be formulated on the basis of bond graphs. Indeed, the port-Hamiltonian formulation of bond graphs without dependent storages has been well investigated. However, little effort has been made towards bond graphs with dependent storages. This is a problem as dependent storages frequently occur in models from many engineering fields. In this paper, we address the explicit port-Hamiltonian formulation of bond graphs with dependent storages. Our idea is to express the port-Hamiltonian dynamics and output as functions of only the system inputs and independent storages. The main result is a rigorous and constructive method to formulate bond graphs containing dependent storages as explicit PHSs. An acadamic example illustrates and verifies our method.",

      "abstract": "The interconnection and damping assignment passivity-based control (IDA-PBC) is well-known for regulating the behavior of nonlinear systems. In underactuated mechanical systems (UMSs), its application requires the satisfaction of matching conditions, which in many cases demands to solve partial differential equations (PDEs). Only recently, the IDA-PBC method has been extended to UMSs in implicit representation, where the system dynamics are described by a set of differential-algebraic equations. In some system classes, this implicit model allows to circumvent the PDE obstacle and to construct an output-feedback law. This paper discusses the design and real-system implementation of the total energy shaping IDA-PBC with an optimal local performance for a portal crane system in implicit port-Hamiltonian representation. The implicit controller is compared with the simplified (explicit) IDA-PBC, introduced by Xue and Zhiyong (2017), which also shapes the total energy and avoids PDEs.",

In this research we especially focus on controller design for fully actuated mechanical systems as a case study. A virtual holonomic constraint force is calculated as a nonlinear feedback input by introducing the coordinate transformation. When some assumptions hold, this feedback successfully converts the original mechanical system into the reduced order port-Hamiltonian system with desired holonomic constraints. A numerical example shows the effectiveness and the property of the proposed virtual holonominc control.",

      "abstract": "Automatic guided vehicles (AGVs) recently have gained increasing attentions and applications, however, frequently stopping to recharge largely reduces service efficiency. Wireless power transfer (WPT) is considered as a practice energization way to solve this problem. In this paper, a passivity-based controller (PBC) and parameter designing method for compensation topology are proposed for AGVs WPT system. The PBC based on port-controlled Hamiltonian system (PCHS) is designed to achieve desired constant systematic working power by regulating the output voltage of DC/DC converter. The LCC-LCC resonant network is analyzed in the principle of the impedance matching method, and a proportional integral (PI) controller is implemented to realize zero steady-state error. Simulation are carried out in PLECS to verify analysis, and results show that proposed controller scheme and compensation designing method ensure the stability of the charging system against load variations, and the fast response performance of the control algorithm is also validated.",

Inspired by the theory of passivity-based control, the proposed method aims at simultaneously and asymptotically stabilize all the desired working modes by means of a static nonlinear state feedback law. An asynchronous external signal is then employed to trigger a hybrid controller in order to switch between the different working modes. The proposed approach is validated by means of simulations performed on the ubiquitous mass-spring-damper system.",

      "abstract": "This paper pertains to the flat representation of a class of port-Hamiltonian (PH) systems and advocates the use of bicausality of Bond graphs for finding appropriate flat outputs. Systems which are differentially flat have several useful properties which can be exploited to generate, for example, optimal trajectories/profiles which ensure constraints satisfaction. For the special case of PH systems combining the power preserving property with the flatness properties leads to effective control strategies for multi-physical systems. Hence, the purpose of this paper is to explore the implications and features of a particular class of PH systems (which can be retrieved from a Bond Graph representation) in finding their flat output representation. We concentrate on the example of an electrical storage system of a DC microgrid to illustrate the proposed theory.",

      "abstract": "This work investigates the position control problem for a soft continuum manipulator in Cartesian space intended for minimally invasive surgery. Soft continuum manipulators have a large number of degrees-of-freedom and are particularly susceptible to external forces because of their compliance. This, in conjunction with the limited number of sensors typically available, results in uncertain kinematics, which further complicates the control problem. We have designed a partial state feedback that compensates the effects of external forces employing a rigid-link model and a port-Hamiltonian approach and we have investigated in detail the use of integral action to achieve position regulation in Cartesian space. Local stability conditions are discussed with a Lyapunov approach. The performance of the controller is compared with that achieved with a radial-basis-functions neural network by means of simulations and experiments on two prototypes.",

      "abstract": "In this paper we address the problem of implementing a stochastic variable admittance control. Both the variable part of the admittance control and the noise affecting the system may concur to the instability of the system. We propose an energy tank approach, based on the theory of stochastic port–Hamiltonian systems and weak passivity, where the energy dissipated by the stochastic system, if any, is stored into the tank to implement the desired actions. As we consider a non–vanishing noise, we need to consider weaker notion of passivity and convergence. We will show how the notion of weak passivity can be properly defined so that equipping a stochastic system with a suitable energy tank, variable admittance control can be efficiently implemented. We prove that the overall system is weakly passive and it converges toward an invariant measure. Simulation results show the effectiveness of the derived theoretical framework.",

      "abstract": "The linear quadratic regulator is a widely used and studied optimal control technique for the control of linear dynamical systems. It consists in minimizing a quadratic cost functional of the states and the control inputs by the means of solving a linear Riccati equation. The effectiveness of the linear quadratic regulator relies on the cost function parameters hence, an appropriate selection of these parameters is of mayor importance in the control design. Port-Hamiltonian system modelling arise from balance equations, interconnection laws and the conservation of energy. These systems encode the physical properties in their structure matrices, energy function and definition of input and output ports. This paper establishes a relation between two classical passivity based control tools for port-Hamiltonian systems, namely control by interconnection and damping injection, with the linear quadratic regulator. These relations allow then to select the weights of the quadratic cost functional on the base of physical considerations. A simple RLC circuit has been used to illustrate the approach.",

More precisely, two viscous compressible fluids are separated by a moving rigid body on a bounded domain (0, L). Thermodynamics is taken into account, leading to two pHs for each physical domain: one associated to the kinetic energy and the other one to the internal energy. No chemical reaction is being considered in the system. A control by mass injection/rejection and heating is then applied at the left end of the first fluid.",

      "abstract": "In this paper we consider the physical-based modeling of 3D and 2D Newtonian fluids including thermal effects in order to cope with the first and second principles of thermodynamics. To describe the energy fluxes of non-isentropic fluids we propose a pseudo port-Hamiltonian formulation, which includes the rate of irreversible entropy creation by heat flux. For isentropic fluids, the conversion of kinetic energy into heat by viscous friction is considered as an energy dissipation associated with the rotation and compression of the fluid. Then, a dissipative port-Hamiltonian formulation is derived for this class of fluids. In the 2D case we modify the vorticity operators in order to preserve the structure of the proposed models. Moreover, we show that a description for inviscid or irrotational fluids can be derived from the proposed models under the corresponding assumptions leading to a pseudo or dissipative port-Hamiltonian structures.",

Specifically, we formulate this transformed model into a perturbed port-Hamiltonian (PH) structure, where the vector of reaction rates is expressed as a matched/unmatched and time-varying disturbance. Then, together with the tracking-error-based control method for the stabilization, two different configurations to compensate such disturbance, including a feed-forward law and a dynamic feedback one, are designed such that the error system asymptotically converges to the set point and preserves the PH representation by assigning an appropriate damping injection. A complex reaction system is used to illustrate the approach.",

      "abstract": "Irreversible port-Hamiltonian systems (IPHS) are an extension of port-Hamiltonian systems (PHS) for irreversible thermodynamics which encompass a large class of thermodynamic systems that may contain reversible and irreversible phenomena. Energy shaping and damping injection are standard structure preserving passivity based control approaches which have proven to be very successful for the stabilization of PHS. However, in the case of irreversible thermodynamics, the non-linear nature of the systems make it non-trivial to apply these approaches for stabilization. In this paper we propose a systematic procedure to perform, in a first control loop, energy shaping by state modulated interconnection with a controller in IPHS form. Then, a second control loop guarantees asymptotic stability by the feedback of a new closed-loop passive output. The approach allows to stabilize IPHS while preserving the IPHS structure in closed-loop, allowing to interpret the closed-loop system as a desired thermodynamic system. The example of the continuous stirred tank reactor is used to illustrate the approach.",

The frequency response of the model at speech frequencies which are significant for sound transmission are found to comparable to existing results in literature. This model can also be used for investigation of tympanic membrane rupture or perforations. Future work will include modelling of the ear canal as horn shaped and inclusion of the angular motion of the tympanic membrane.",

      "abstract": "The main objective of this paper is to present a novel Port-Hamiltonian based model of the human inner ear. This model can be used in the assessment and diagnosis of the human inner ear diseases, for instance, Noise Induced Hearing Loss. It may also be used for understanding of sound transmission in the inner ear. The Cochlear Partition is modelled as a pair of Euler-Bernoulli beams coupled together by a linear massless distributed spring. The fluids in the Scala Vestibuli and Scala Tympani are also included in the model. The Cochlear displacement velocity is mainly enhanced by the Outer Hair Cells activities. For frequencies greater than 1 KHz the enhancements become very significant. The developed model also includes the outer hair cells. The model was validated against existing inner ear models and the results were found to be comparable. Future improvements to the model would involve inclusion of the auditory nerve to the model.",

Despite the large literature on mixed finite elements, no rigorous analysis of the connections between mixed elements and port-Hamiltonian systems has been carried out. In this paper we demonstrate how existing methods can be employed to discretize dynamical plate problems in a structure-preserving way. Based on convergence results of existing schemes, new error estimates are conjectured; numerical simulations confirm the expected behaviors.",

A key aspect of these systems is that the fluid typically flows across spatially and temporally varying cross-sections. We, first, show that not any choice of state-variables may be apt for obtaining a port-Hamiltonian realization under spatially varying cross-section. We propose a modified choice of the state-variables and then represent fluid dynamical systems in port-Hamiltonian representations. We define these port-Hamiltonian representations under spatial variation in the cross-section with respect to a new proposed state-dependent and extended Stokes- Dirac structure. Finally, we account for temporal variations in the cross-section and obtain a suitable structure that respects key properties, such as, for instance, the property of dissipation inequality.",

In both frameworks, a dynamic controller based on the energy-Casimir method is derived in order to stabilise certain equilibrias. Moreover, we propose distributed-parameter observers deduced by exploiting damping injection for the observer error. Finally, we compare the approaches by means of an in-domain actuated vibrating string and show the equivalence of the control schemes derived in both frameworks.",

This class of models enable one to exploit the structure of port-Hamiltonian systems for feedback control design while relaxing the constraint of deriving an exact structured port-Hamiltonian representation. For a given stabilizable nonlinear system, and with some assumptions on the unstructured part of the dynamics, a stabilizing control law is designed and asymptotic stability of a desired equilibrium of the system is demonstrated. A numerical illustration of the proposed approach is presented to demonstrate the design method.",

      "abstract": "Nonholonomic mechanical systems encompass a large class of practically interesting robotic structures, such as wheeled mobile robots, space manipulators, and multi-fingered robot hands. However, few results exist on the cooperative control of such systems in a generic, distributed approach. In this work we extend a recently developed distributed Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) method to such systems. More specifically, relying on port-Hamiltonian system modelling for networks of mechanical systems, we propose a full-state stabilization control law for a class of nonholonomic systems within the framework of distributed IDA-PBC. This enables the cooperative control of heterogeneous, underactuated and nonholonomic systems with a unified control law. This control law primarily relies on the notion of Passive Configuration Decomposition (PCD) and a novel, non-smooth desired potential energy function proposed here. A low-level collision avoidance protocol is also implemented in order to achieve dynamic inter-agent collision avoidance, enhancing the practical relevance of this work. Theoretical results are tested in different simulation scenarios in order to highlight the applicability of the derived method.",

The proposed methodology considers a dynamic output feedback controller such that the linearized relationship between the control inputs and the outputs of interest can be interpreted as a high-order compensator. Accordingly, the controllers are studied in the framework of the transfer functions, and the control gains can be tuned through a frequency analysis approach while ensuring the stability of the closed-loop system. Additionally, the controllers have the advantage that they do not require velocity measurements. We illustrate the applicability of the proposed methodology through a numerical example.",

Two different cases are considered to describe the energy fluxes in isentropic compressible and incompressible fluids. In the compressible case, the viscoelastic effects of shear and dilatational strains on the stress tensor are described individually through the corresponding constitutive equations. In the incompressible case, an approach based on the bulk modulus definition is proposed in order to obtain an appropriate characterization, from the port-Hamiltonian point of view, of the pressure and nonlinear terms in the momentum equation, associated with both dynamic pressure and vorticity of the flow.",

      "abstract": "An irreversible port-Hamiltonian system formulation of a class of piezoelectric actuator with non-negligible entropy increase is proposed. The proposed model encompasses the hysteresis and the irreversible thermodynamic changes due to mechanical friction, electrical resistance and heat exchange between the actuator and the environment. The electromechanical dynamic of the actuator is modeled using a non-linear resistive-capacitive-inductor circuit coupled with a mass-spring-damper system, while the non-linear hysteresis is characterized using hysterons. The thermodynamic behavior of the model is constructed by making the electromechanical coupling temperature dependent, and by characterizing the entropy produced by the irreversible phenomena. By means of numerical simulations it is shown that the proposed model is capable of reproducing the expected behaviors and is in line with reported experimental results.",

      "abstract": "This paper proposes a proportional-integral passivity-based control strategy to stabilize the transformed model of a chemical reaction system, described by vessel extents. It is shown that the transformed model belongs to a class of perturbed non-standard Port-Hamiltonian systems with time-varying unmatched (endogenous) disturbance, thereby limiting the applicability of the integral-action-based design method proposed by Donaire and Junco [A. Donaire and S. Junco. Automatica, 2009] because of a lack of interconnection. The developed method adapts a change of coordinates for the design to add an appropriate interconnection between relative-degree-one states and higher-relative-degree states that allows injecting a necessary damping to achieve asymptotic stability and preserving the PH representation of extended closed-loop system. A reversible reaction system is used to illustrate the proposed approach.",

This method unifies two methods, sliding mode control and passivity-based control, and has the advantages of both control methods. This paper proposes a pair of a pre-coordinate transformation and a state feedback so that we obtain a desired error port-Hamiltonian system that describes the dynamics of the tracking error. This approach enables us to obtain appropriate design parameters satisfying a kind of matching condition to realize sliding mode control with a Lyapunov function. The effectiveness of the proposed method is demonstrated by a numerical simulation.",

The resulting control law depends on distributed system states that cannot be measured, and therefore, we additionally design an infinite-dimensional observer by exploiting the port-Hamiltonian system representation. A Kirchhoff-Love plate serves as an example in order to demonstrate the proposed approaches.",

At first, a class of autonomous port-Hamiltonian systems whose dynamic is described by coupled PDEs and (nonlinear) ODEs is presented, and some properties (i.e., well-posedness and asymptotic stability of the origin) investigated. Secondly, an energy-based control design methodology is discussed. The finite-dimensional subsystem is equipped with an input, and a procedure for designing a state-feedback control action that maps the open-loop dynamic to a target one still in port-Hamiltonian form is illustrated. The idea is that the corresponding error system meets the requirements regarding the asymptotic stability of the origin stated in the first part of the paper. In this way, asymptotic convergence of the trajectories to the desired equilibrium configuration can be proved.",

The proposed approach combines statistical physics and port-Hamiltonian formulation, to produce macroscopic power balanced systems with reduced complexity.

The method is illustrated on two applications: an ideal gas in a thermostat, and a ferromagnet in a thermostat.",

      "abstract": "In this paper, the observer design problem for Port-Controlled Hamiltonian systems is approached. It is considered a particular class of these systems and a full-order order observer is proposed which belongs to the Structure Preserving approach since it is a copy of the original system with an output corrective term. Concerning the class of systems, it corresponds to nonlinear systems that exhibit nonlinearities given by the products between components of the state vector. The fact that this kind of behavior corresponds to a special property of the interconnection matrix is exploited to obtain a representation for the estimation error dynamics that is suitable to formally state the convergence properties of the observer. The usefulness of the contribution is illustrated by solving the speed observation problem for a Permanent Magnet Synchronous Motor.",

Structure-preserving model order reduction by parameter optimization, Preprint arXiv:2011.07567]. This strategy reduces the computational demand and the required a priori knowledge about the given full-order model, while at the same time retaining a high accuracy compared to other structure-preserving but also unstructured MOR algorithms. A numerical study with a port-Hamiltonian benchmark system demonstrates the effectiveness of our method when combined with this new adaptive sampling strategy. We also investigate the distribution of the sample points.",

Finally, the structure-preserving numerical scheme provided by the Partitioned Finite Element Method (PFEM) of [Serhani & al., 2019] is applied to the incompressible dissipative fluid in 2D.",

      "abstract": "The dissipative Shallow Water Equations (DSWEs) are investigated as port-Hamiltonian systems. Dissipation models of different types are considered: either as nonlinear bounded operators, or as linear unbounded operators involving a classical diffusion term in 1D, or the vectorial Laplacian in 2D. In order to recast the dissipative SWE into the framework of pHs with dissipation, a physically meaningful factorization of the vectorial Laplacian is being used, which nicely separates the divergent and the rotational components of the velocity field. Finally, the structure-preserving numerical scheme provided by the Partitioned Finite Element Method (PFEM) is applied to the nonlinear bounded dissipative fluid models. For the linear unbounded cases, a change of variables is highlighted, to transform the DSWEs into a new pHs with a polynomial structure, which proves more suitable for numerics.",

In particular, we consider examples arising from the structural dynamics of beams. Port-Hamiltonian beam models can be readily discretized by using mixed finite elements. The resulting numerical models are used to generate the input-output data. The data-driven realization is then compared to the original numerical model in terms of its bode plot and energy trend.",

In the present paper this is extended to pairs of linear differential operators defining a formally skew-adjoint relation between flows and efforts. Furthermore it is shown how the underlying repeated integration by parts operation is streamlined by the use of two-variable polynomial calculus. Dirac structures defined by formally skew adjoint operators together with differential operator effort constraints are treated within the same framework. Finally it is sketched how the approach can be also used for Lagrangian subspaces on bounded domains.",

      "abstract": "This paper proposes a passivity-based approach using bearing and velocity information for a triangular formation control with the interaction topology constrained by angles. The controller framework is designed using virtual couplings on the relative measurements related to the edges. The different measurements associated with the edges are mapped by the measurement Jacobian, which is calculated by the time-evolution of the measurement. To avoid unavailable distance measurements in the control law, an estimator is designed based on port-Hamiltonian theory using bearing and velocity measurements. The stability analysis of the closed-loop system is provided and simulations are performed to illustrate the effectiveness of the approach.",

The approach is twofold: (i) we apply our technique for linear viscous damping identification to improve the accuracy of the selected control technique, and (ii) we implement a passivity-based controller to stabilize and reduce the oscillations by selecting the control parameters properly in accordance with the identified damping. Moreover, we provide theoretical analysis for a particular passivity-based control approach on its effectiveness for reducing such oscillations. Also, we validate the methodology by implementing it experimentally in a planar manipulator.",

      "abstract": "In this paper, we analyze the stability of hydraulic, i.e. pressure and flow, equilibria in 4th generation district heating networks (DHNs). We consider the hydraulic behavior of a general class of DHNs with an arbitrary number of distributed heat generation units (DGUs) and end-users connected through a network of pipes. For each subsystem, we first derive a model in form of an explicit port-Hamiltonian system with nonlinear resistive structure. Based on these models and with methods from equilibrium-independent passivity (EIP), we prove the stability of the DHN’s hydraulic equilibria. From our results, we deduce requirements for a plug-and-play control of DHNs and draw conclusions for future work.",

      "abstract": "We address the problems of modeling and controlling multi-energy microgrids (meMGs) composed of an electrical and a thermal system, which are connected via heat pumps (HPs). At first, we model the individual subsystems in a port-Hamiltonian (pH) framework. Then, by exploiting the structural properties of pH systems, we interconnect the subsystems in a passive manner and show that the overall meMG is shifted passive with respect to the control input-output mapping. We then use this property to propose a distributed passivity based-control (PBC) that addresses frequency and temperature regulation by utilizing the resources in the meMG in a proportional fashion and renders the closed-loop equilibrium asymptotically stable.",

In particular, the formation network is represented by a directed communication graph with leaders and followers, where each agent is described as a port-Hamiltonian system with a constant mass matrix. Moreover, we adopt a distributed parameter approach to prove the scalable asymptotic stability of the network formation, i.e., the scalability with respect to the network size and the specific formation preservation. A simulation case illustrates the effectiveness of the proposed control approach.",

      "abstract": "The design of control engineering applications usually requires a model that accurately represents the dynamics of the real system. In addition to classical physical modeling, powerful data-driven approaches are increasingly used. However, the resulting models are not necessarily in a form that is advantageous for controller design. In the control engineering domain, it is highly beneficial if the system dynamics is given in PCHD form (Port-Controlled Hamiltonian Systems with Dissipation) because globally stable control laws can be easily realized while physical interpretability is guaranteed. In this work, we exploit the advantages of both strategies and present a new framework to obtain nonlinear high accurate system models in a data-driven way that are directly in PCHD form. We demonstrate the success of our method by model-based application on an academic example, as well as experimentally on a test bed.",

The syntax enables the modular and hierarchical specification of the composition pattern of lumped and distributed-parameter models. The semantics reflects the first and second law of thermodynamics as structural properties. Interconnected and hierarchically defined models of multiphysical thermodynamic systems can thus be expressed in a formal language accessible to humans and computers alike. We discuss a composed model of the Navier-Stokes-Fourier fluid on a fixed spatial domain as an example of an open distributed-parameter system. At the top level, the system comprises five subsystems which model kinetic energy storage, internal energy storage, thermal conduction, bulk viscosity, and shear viscosity.",

Firstly, the Port Hamiltonian formulation of the dynamics of the phase field variable, governed by the Allen-Cahn equation, is recalled. It is based on adding to the phase field variable, its gradient, and extending the system with its dynamics. Secondly, the model is completed by the energy balance equation for the heat conduction and the complete Port Hamiltonian model is derived. Thirdly an Algebro-differential Port Hamiltonian representation is suggested, where the Port Hamiltonian system is defined on a Lagrangian submanifold, allowing to use directly the variables defining the thermodynamical data.",

In order to simulate such a process, phase field models such as Allen-Cahn and Cahn-Hilliard can be used. In this paper, a port-Hamiltonian formulation of the Allen-Cahn equations is used and coupled to heat conduction, which allows for a thermodynamically consistent system to be written with the help of the entropy functional. In a second part, the Partitioned Finite Element Method, a structure-preserving spatial discretization method, is applied to the Allen-Cahn equation; it gives rise to an exact free energy balance at the discrete level. Finally some numerical results are presented.",

The key is to express the variational problem based on the principle of virtual power, with both the Dirichlet (velocity) and Neumann (stress) boundary conditions imposed in a weak sense. As a consequence, the formal skew-adjointness of the system operator becomes directly visible after integration by parts, and, after compatible FE discretization, the boundary degrees of freedom of both causalities appear as explicit inputs in the resulting state space model. The rationale behind our formulation is illustrated using a lumped parameter example, and numerical experiments on a one-dimensional rod show the properties of the approach in practice.",

The first approach is based on a direct low order structure preserving discretization while the second approach arise from the structure preserving model reduction of a high order discretzed model. Two passivity-based control techniques, namely control by interconnection and damping injection, are used to change the equilibrium point and the convergence rate of the closed-loop system. An Euler-Bernoulli beam example is used to illustrate the findings by means of discussion and numerical simulations.",

      "abstract": "In this paper, we propose a full state-feedback boundary control strategy for a one-dimensional wave-like equation with spatially varying parameters and indefinite damping coefficient. We consider Dirichlet boundary conditions at one end of the spatial domain and actuation at the other end. The control design relies on the backstepping methodology and aims at assigning the distributed damping (which determines the decay rate of the solutions) of the closed-loop system. The problem is formulated using the port-Hamiltonian system framework that allows the introduction of tuning parameters with clear physical interpretations for both backstepping transformations and achievable closed-loop behavior. The overall design is carried out on the vibrating string system example. Simulations illustrate the performance of the controller.",

      "abstract": "A prevalent theme throughout science and engineering is the ongoing paradigm shift from isolated systems to open and interconnected systems. Port-Hamiltonian theory developed as a synthesis of geometric mechanics and network theory. The possibility to model complex multiphysical systems via interconnection of simpler components is often advertised as one of its most attractive features. The development of a port-Hamiltonian modelling language however remains a topic which has not been sufficiently addressed. We report on recent progress towards the formalization and implementation of a modelling language for exergetic port-Hamiltonian systems. Its diagrammatic syntax is the operad of undirected wiring diagrams with an interpretation akin to bond graphs. Together with a port-Hamiltonian semantics defined as an operad functor, this enables a modular and hierarchical approach to model specification.",

Due to the fact that the equations of motion of a filamentous body are based on the theory of geometrically nonlinear mechanical systems, the port-Hamiltonian formulation is expressed by means of its co-energy (effort) variables. The resulting port-Hamiltonian state space model features a quadratic Hamiltonian and the nonlinearity is reflected in the state dependence of its interconnection matrix. Numerical experiments generated with FEniCS illustrate the properties of the resulting finite element models.",

We apply our recent approach from structure mechanics, which relies on the weak imposition of both Neumann and Dirichlet BCs based on a suitable variational principle, to the class of PH systems of two conservation laws. We illustrate (a) starting with the integral conservation laws the transition to an exterior calculus representation suitable for FE approximation according to Farle et al. (2013). Based thereon, we show (b) the variational formulation with weakly imposed BCs of both types. We discuss (c) on a simple example on a quadrilateral mesh the structure and the variables of the resulting FE models compared to the equations derived from a direct discrete approach on dual cell complexes. We (d) provide the corresponding FEniCS code for download.",

      "abstract": "In this contribution, port-Hamiltonian systems with non-homogeneous mixed boundary conditions are discretized in a structure-preserving fashion by means of the Partitioned FEM. This means that the power balance and the port-Hamiltonian structure of the continuous equations is preserved at the discrete level. The general construction relies on a weak imposition of the boundary conditions by means of the Hellinger-Reissner variational principle, as recently proposed in [Thoma et al., 2021]. The case of linear hyperbolic wave-like systems, including the elastodynamic problem and the Maxwell equations in 3D, is then illustrated in detail. A numerical example is worked out on the case of the wave equation.",

      "abstract": "Different from mechanic or reversible systems, such as port-Hamiltonian systems (PHS), which preserves the energy or the Hamiltonian, irreversible PHS (IPHS) also satisfy the second law of Thermodynamics, i.e., the internal entropy production of the system is always greater or equal to zero. Hence, when considering the interconnection of IPHS, it must be so that the first and second laws of Thermodynamics are satisfied, implying that the interconnection must be power-preserving and entropy-increasing. In this work the conditions for a thermodynamic admissible interconnection of IPHS have been studied and characterized. The interconnection law is given by a state modulated input-output feedback, in which each modulating function is related and defined by the corresponding irreversible thermodynamic driving force induced by the interconnection. The interconnection law also encompasses the reversible interactions, and can be interpreted as a generalization of a power-preserving interconnection to deal with thermodynamic systems. The result has been illustrated on the abstract interconnection of purely thermodynamic and thermo-mechanic systems, and on the examples of an ideal heat-exchanger and a gas-piston system.",

      "abstract": "Recently, passivity-based sliding mode control has been proposed for mechanical port-Hamiltonian systems. This controller has properties of both sliding mode control and passivity-based control, and Lyapunov stability is ensured by a Hamiltonian function with a non-smooth potential function. In the authors’ previous study, a special form of non-smooth potential function is considered and there are few parameters to adjust the controller for various control objectives. This paper proposes a new passivity-based sliding mode controller based on a wider class of potential functions. This approach enables us to reduce chattering and improve the behavior in reaching mode by adjusting parameters. The effectiveness of the proposed method is demonstrated by a numerical simulation.",

To this end, we find a smooth approximation of the inverse of the function that describes such a nonlinearity. Then, we propose an energy and damping injection approach — based on the PI-PBC technique — that compensates for the dead-zone. Moreover, we provide an analysis of the performance of the proposed controller near the equilibrium. We conclude this paper by experimentally validating the results on a two degrees-of-freedom planar manipulator.",

      "abstract": "In this paper, we design a sampled-data distributed output feedback controller to achieve output consensus for linear continuous-time port-Hamiltonian systems in presence of unknown disturbances. The key idea is borrowed from Krasovskii passivity-based output consensus control for continuous-time dynamics. To conceptualise this rationale to sampled control systems, we deal with a discrete-time system arising from a symplectic discretization of a continuous-time linear port-Hamiltonian system, such as the implicit midpoint method. As a preliminary step, we introduce the concept of Krasovskii passivity for discrete-time systems and further show that a discretized linear port-Hamiltonian system is Krasovskii passive in the discrete-time sense. Then, based on the discrete-time version of Krasovskii passivity, we develop a sampled-data output feedback controller to achieve output consensus. The proposed sampled-data controller can be understood as a symplectic discretization of the continuous-time output consensus controller. Finally, we illustrate the effectiveness of the main result by achieving current sharing in a DC power network.",

      "abstract": "Despite the immense success of neural networks in modeling system dynamics from data, they often remain physics-agnostic black boxes. In the particular case of physical systems, they might consequently make physically inconsistent predictions, which makes them unreliable in practice. In this paper, we leverage the framework of Irreversible port-Hamiltonian Systems (IPHS), which can describe most multi-physics systems, and rely on Neural Ordinary Differential Equations (NODEs) to learn their parameters from data. Since IPHS models are consistent with the first and second principles of thermodynamics by design, so are the proposed Physically Consistent NODEs (PC-NODEs). Furthermore, the NODE training procedure allows us to seamlessly incorporate prior knowledge of the system properties in the learned dynamics. We demonstrate the effectiveness of the proposed method by learning the thermodynamics of a building from the real-world measurements and the dynamics of a simulated gas-piston system. Thanks to the modularity and flexibility of the IPHS framework, PC-NODEs can be extended to learn physically consistent models of multi-physics distributed systems.",

      "abstract": "In this paper, we propose an energy based control approach for a class of underactuated soft robotic systems. The considered case study consists of an elastic structure driven by soft dielectric elastomer actuators, and is able to achieve large bending displacement thanks to a bi-stable design concept. The bi-stability feature, however, causes the system to exhibit an unstable behavior in open-loop. After providing a port-Hamiltonian description of the soft robotic system, sufficient conditions for the existence of an energy based stabilizing controller are provided. A linear matrix inequality approach is then proposed to practically address the design of the controller gain. The effectiveness of the method is verified by means of simulation studies, conducted on an experimentally validated model of the real-life device.",

Stability conditions are obtained based on the port-Hamiltonian structure of the droop control in grid-forming converters. We show that conventional grid-forming converters have a port-Hamiltonian structure in the multi-converter power system. A simple and direct estimation of the region of attraction is obtained. In addition, we proposed droop control with an angle feedback that ties two converters in order to improve transient response. This control maintains the port-Hamiltonian structure and hence the stability properties of the conventional droop. Numerical experiments show the accuracy of the model and the superior performance of the proposed control.",

      "abstract": "This paper aims at describing a synthesis procedure of discrete-time, energy-based regulators for continuous-time port-Hamiltonian systems. The methodology consists of three steps. The first twos deal with the definition of a discrete-time approximation of the plant to be successively employed in the development of the control law. Here, the focus is mainly on the last step, i.e. on how to interconnect digital controller and plant. The coupling is implemented via a zero-order hold and relies on the solution of an optimisation problem that determines the “best” and “minimal” correction to be applied to the nominal action to achieve the same performances obtained when the regulator is in closed-loop with the discrete-time model of the plant. This is the reference scenario used by the designer to develop and tune the control law. The procedure (time-discretisation, control design and coupling implementation) is illustrated in an example.",

      "abstract": "Switching physical systems are ubiquitous in modern control applications, for instance, locomotion behavior of robots and animals, power converters with switches and diodes. The dynamics and switching conditions are often hard to obtain or even inaccessible in case of a-priori unknown environments and nonlinear components. Black-box neural networks can learn to approximately represent switching dynamics, but typically require a large amount of data, neglect the underlying axioms of physics, and lack of uncertainty quantification. We propose a Gaussian process based learning approach enhanced by switching Port-Hamiltonian systems (GP-SPHS) to learn physical plausible system dynamics and identify the switching condition. The Bayesian nature of Gaussian processes uses collected data to form a distribution over all possible switching policies and dynamics that allows for uncertainty quantification. Furthermore, the proposed approach preserves the compositional nature of Port-Hamiltonian systems. A simulation with a hopping robot validates the effectiveness of the proposed approach.",

Starting from the partial differential Euler equations describing the dynamical flow of gas in a pipeline, the method of lines is employed to obtain a lumped-parameter model, which simplifies to a nonlinear third-order PHS. Parallels between gas networks and power systems are drawn by showing that the obtained pipeline PHS model has the same π-representation as electrical transmission lines. Moreover, to assist future control design, additional passivity properties of the pipeline PHS model are analysed and discussed. By comparing the proposed PHS models against other models in a standard simulation, we show that the simplifying assumptions have no material effect on the model fidelity. The proposed pipeline and network models can serve as a basis for passivity-based control and analysis while the power system parallels facilitate the transfer of existing methods.",

      "abstract": "This paper proves a stability property of mechanical port-Hamiltonian systems with kinetic potential energy shaping (KPES) with respect to external disturbances using the input-to-state stability (ISS) characterization. Such analysis is quite useful when constructing an output feedback controller consisting of a KPES state feedback controller and a state observer, since the stability of the resulting output feedback closed-loop system can be guaranteed by such stability by regarding the estimation error of the observer as the external disturbance to the KPES state feedback system. If this state feedback system is ISS with respect to the state estimation error and if this error is asymptotically stable, then the origin of the closed-loop system is asymptotically stable. Therefore, it is possible to obtain an output feedback controller consisting of a KPES state feedback controller with any asymptotic state observer. Numerical simulations verify the ISS property of the KPES state feedback system.",

The approach provides an optimal criterion for choosing a free parameter of the controller so that the closed-loop system converges to the best approximation of the desired imposed shape. The methodology is based on the so called control by interconnection method and structural invariant from which an analytical expression is obtained for the shapes that the system can actually achieve. An Euler-Bernoulli beam model with pointwise inputs is used as example to illustrate the proposed methodology.",

We recall the DG discretization procedure which is based on a subdivision of the computational domain, an elementwise weak formulation with up to two integrations by parts, and the interconnection of the elements using different numerical fluxes. We present the interconnection of the element models, which is power preserving in the case of conservative (unstabilized) numerical fluxes, and we set up the resulting global PH state space model. We discuss the properties of the obtained models, including the effect of the flux stabilization parameter on the spectrum. Finally, we show simulations with different parameters for a boundary controlled linear hyperbolic system.",

      "abstract": "Irreversible Port Hamiltonian Systems are a deviation from Port Hamiltonian Systems which embeds the definition of the irreversible phenomena taking place in the system. They are defined with respect to a quasi-Poisson bracket which ensures the positiveness of the entropy generation and is expressed in terms of the total entropy of the system. The port maps, however, associated with the conjugated port variables, were poorly justified and lacked any physical characterization. In this paper, we suggest a novel definition of the port maps which allows to recover not only the energy balance equation (when the Hamiltonian equals the total energy of the system) but also a entropy balance equation including the irreversible entropy creation term at the interface (the port) of the system in addition to the entropy creation term due to internal irreversible phenomena.",

      "abstract": "A damping assignment control law for infinite-dimensional port-Hamiltonian systems in one-dimensional space with actuators and sensors located at the spatial boundaries is proposed with the novelty that the boundary damping is unknown. This allows us to fix a desired decay of energy for the cases in which the system is over-damped, poorly damped, and even with negative damping. We propose an observer composed of an infinite-dimensional model and a finite-dimensional one for the state and parameter estimation. The asymptotic convergence of the observer is shown using LaSalle's invariance principle assuming that the trajectories are pre-compact. Finally, an observer-based adaptive output feedback controller is proposed for the damping assignment in the closed loop. The passivity of the closed-loop system is guaranteed with respect to the initial Hamiltonian of the system under the assumption that the observer is initialized identically to the current state and close enough to the parameter value. The transmission line is used to exemplify this approach.",

      "abstract": "Many nonlinear model predictive controls (NMPCs) are suffering from the computational cost as well as the stability for mechatonic systems in several situations. The paper proposes a simple but general fast search method of design parameters for stable NMPCs. The computational cost is reduced, that is, each closed-loop simulation runs faster and the number of the (stable or unstable) closed-loop simulations is decreased. First, we introduce dimensions (SI units) for the objective function which is usually dimensionless unlike the physical dynamics and constraints. Second, we propose a fast search method by mixing a nondimensionalization for the objective function and another nondimensionalization for the physical dynamics and constraints. Finally, the effectiveness of the proposed method is confirmed by a numerical experiment via an actual hydraulic cylinder. Almost 20% reduction of the computational cost is achieved to find good design parameters for the stable NMPCs. Remarkably, the proposed method is generally applicable to many NMPCs and is not restricted to a specific one.",

Inspired by the Port Hamiltonian framework, we use the Riemann invariants of the energy states to reformulate this problem as stabilizing a chain of two coupled hyperbolic subsystems with actuation at the in-between boundary. After applying successive transforms, it is shown to be equivalent to stabilizing a neutral-type delay-differential equation. A suitable controller is derived using the backstepping methodology with a Fredholm integral transform. Some simulations illustrate this approach.",

      "abstract": "Boundary controlled irreversible port-Hamiltonian systems (BC-IPHS) defined on 1, 2 and 3-dimensional spatial domains are defined by extending the formulation of reversible BC-PHS to irreversible thermodynamic systems controlled at the boundaries of their spatial domain. The structure of BC-IPHS has a clear physical interpretation, characterizing the coupling between energy storing and energy dissipating elements. By extending the definition of boundary port variables of BC-PHS to deal with the irreversible energy dissipation, a set of boundary port variables is defined so that BC-IPHS are passive with respect to a given set of conjugated inputs and outputs. As for finite-dimensional IPHS and 1-D infinite-dimensional IPHS recently defined in [Ramirez et al., Chem. Eng. Sci. (2022)], the first and second laws of Thermodynamics are satisfied as a structural property of the system. As a common thread, the 3D compressible fluid example is worked out to illustrate the proposed approach: both the reversible case of the isentropic fluid and the irreversible case of the non-isentropic fluid are presented.",

This paper considers the Control-by-Interconnection interpretation of integral control when applied to port-Hamiltonian systems. The interpretation allows the integral controller to be described as a port-Hamiltonian system independent of the plant dynamics. Using this interpretation, we present physical realizations of integral control for a mechanical and an electro-mechanical system.",

      "abstract": "In this work, a new second-order sliding mode controller for mechanical port-Hamiltonian systems is proposed. The authors’ former paper proposed a passivity-based sliding mode controller based on the kinetic-potential energy shaping (KPES). This controller is able to achieve only first-order sliding mode control since the KPES allows us to embed a subsystem, whose dimension is the same as that of the input, into the closed-loop system. The present paper extends the KPES to incorporate a higher-order subsystem in the closed-loop system, which enables us to obtain the subsystem that can realize second-order sliding mode control. The proposed controller is a unification of a passivity-based controller and a second-order sliding mode controller which does not cause undesirable chattering phenomena. It ensures finite-time convergence of the subsystem and asymptotic stability of the entire closed-loop system by utilizing two Lyapunov functions. A numerical example demonstrates the effectiveness of the proposed method.",

The proposed non-linear model is identified under different applied voltages and pressures, and validated against experimental results with relative errors of less than 0.3%. Subsequently, two passivity-based controllers are designed to stabilize the actuator at a desired position. The first controller is designed using control by interconnection. The second one considers additional integral action to reject disturbances while preserving the passivity of the closed-loop system.",

Compared to pure data-driven approaches, it relies on solid physics priors based on the Gaussian process port-Hamiltonian systems (GP-PHS) framework. This foundation guarantees that the learning procedure adheres to the fundamental physical laws governing real-world systems. Utilizing the Bayesian learning method, PyGpPHs enables physics-informed predictions with uncertainty quantification, which are based on the posterior distribution over Hamiltonians. The PyGpPHs toolbox is designed to make Bayesian learning with physics prior accessible to the learning and control community. PyGpPHs can be installed through an open-source link 1.",

      "abstract": "It is well known that the Lagrangian and Hamiltonian descriptions of field theories are equivalent at the discrete time level when variational integrators are used. Besides the symplectic Hamiltonian structure, many physical systems exhibit a Hamiltonian structure when written in mixed form. In this contribution, the discrete equivalence of Lagrangian, symplectic Hamiltonian and mixed formulations is investigated for linear wave propagation phenomena. Under compatibility conditions between the finite elements, the Lagrangian and mixed formulations are indeed equivalent. For the time discretization the leapfrog scheme and the implicit midpoint rule are considered. In mixed methods applied to wave problems the primal variable (e.g. the displacement in mechanics or the magnetic potential in electromagnetism) is not an unknown of the problem and is reconstructed a posteriori from its time derivative. When this reconstruction is performed via the trapezoidal rule, then these time-discretization methods lead to equivalent formulations.",

The mechanical model provides a description of large deformations including finite elastic and inelastic strains in a generalized Maxwell model. It is shown that the overall system results from a power-preserving interconnection of PH subsystems. By using a structure-preserving mixed finite element approach, a finite-dimensional PH model is derived. Eventually, midpoint discrete derivatives are employed to deduce an energy-consistent time-stepping method, which inherits discrete-time dissipativity for the irreversible system. An example simulation illustrates the numerical properties of the present approach.",

Yet, properly modeling irreversibility remains a challenge as one has to include a nonlinear relation between flows and efforts, leading to a nonlinear Dirac structure. In this work, we will focus on the modelling of a distributed coupling of the heat and wave equations as pH systems. In particular, the representation of the coupled dynamics as an irreversible pH system is presented and its properties discussed. A discretization in space which preserves both the second and first principles of thermodynamics is detailed. Finally some numerical results are presented.",

      "abstract": "This paper contributes to the application of port-Hamiltonian systems (pHs) theory in the context of fixed-wing airplanes, an area challenged by the difficulty of introducing aerodynamics in this framework. Expanding on recent initiatives that applied pHs theory to fixed-wing airplane dynamics - a move that simplified thrust and aerodynamics - our study introduces a comprehensive longitudinal dynamics formulation. This approach not only clarifies these earlier models by aligning more closely with traditional airplane dynamics equations but also integrates physical parameters from an A300 airplane model. By addressing and enhancing the thrust and aerodynamic representations, our formulation achieves a more accurate depiction of airplane dynamics. This work marks a step forward in the ongoing efforts to adapt pHs theory for aerospace engineering, laying the groundwork for more effective modeling and control strategies in this field.",

Recent developments have extended this representation to multiphysical systems. In this paper, a PH formulation of a Liquid Propelled Rocket Engine model is proposed. Starting from a classical state-space representation, a new model is derived which allows to demonstrate the global passivity feature of the system using the property of passivity inheritance by composition of several PH subsystems. The resulting representation allows to consider passivity-based control perspective for this class of complex thermodynamics system.",

      "abstract": "The paper discusses a Casimir based analysis of the General Actuator Model by Neville Hogan in which all actuators are classified into only two types: the Norton type and the Thevenin (Thévenin) type. Since the original version of the General Actuator Model was very weakly defined, the link to the fruitful port Hamiltonian framework is not clarified yet. First, a subset of the General Actuator Model is focused and we discuss a new port based modeling of the two types of the General Actuator Model. To clarify the link, a relation using the Casimir function between the two types is found as their structural properties. Second, a special mechatronic example whose energy is non-quadratic is analyzed as well as the popular mass-spring example. A hidden energy structure in these two examples is revealed unexpectedly. Not only a new observation for the special mechatronic example but also a new look at the popular mass-spring example are provided.",

For that purpose, we use a modular approach and consider the HASEL actuator as an interconnection of elementary subsystems. Each subsystem is modeled by an electrical component consisting of a capacitor in parallel with an inductor connected through the conservation of volume of the moving liquid to a mechanical structure based on inertia, linear, and torsional springs. The parameters are then identified, and the model is validated on the experimental setup. Position control is achieved by using Interconnection and Damping Assignment-Passivity Based Control (IDA-PBC) with integral action (IA) for disturbance rejection. Simulation results show the Efficiency of the proposed controller.",

      "abstract": "The Port-Hamiltonian formalism has demonstrated to be useful in different applications, allowing to explore structural properties to obtain stable controls. A common approach is to design controls in a continuous domain although, in practice, they are implemented in discrete time. However, the study of discrete-time port-Hamiltonian systems is challenging since the system may lose structural properties such as passivity after discretization. This paper shows that passivity is conserved for the backward Euler discretization method when the Hamiltonian is convex, and its gradient is Lipschitz. This result is relevant for power systems applications such as the control of two-area systems, high-voltage direct-current transmission, and microgrids. Although our method is simple and preserves passivity, it does not preserve the symplectic structure of the hamiltonian.",

We show how they can be used to translate Control by Interconnection to the discrete-time setting. We set up the discrete-time plant and controller model and compute the discrete-time inputs for which the desired equilibrium of the continuous-time closed-loop system becomes a stable equilibrium of the discrete-time models. To obtain a continuous-time control signal for the plant system in the sampling interval, these discrete inputs are then interpolated by a polynomial. The advantages of the proposed approach at large sampling times are illustrated in simulations using the example of the controlled pendulum.",

      "abstract": "In this paper the observer design problem for a class of nonlinear Port-Controlled Hamiltonian (PCH) systems is addressed. The approached class is characterized, first, by considering that the state vector can be divided into measurable and non measurable components and, second, in terms of the structure of the Hamiltonian energy function. Under these conditions, the main contribution of this paper is to propose an observer design methodology that considers as a basic feature the decomposition of the system as the interconnection of two PCH subsystems to obtain a reduced order observer. Regarding the Hamiltonian function, it is proved that the proposed methodology is able to deal with the same energy function that, to be best of the authors knowledge, is considered as the state-of-the-art contribution of the field. The proposed observer design is evaluated in a magnetic levitation system comparing its convergence characteristics with respect to another kind of observer that is reported in the literature.",

The new concept of dissipative Differential Hamiltonian dynamics is proposed providing a weaker notion of contractive dynamical system. Furthermore, the Differential Hamiltonian notion is extended to the definition of Differentially passive port-Hamiltonian system. We describe explicit conditions to exploit the ‘natural’ Differential Hamiltonian function as differential storage function for the port-Hamiltonian system dynamics.",

      "abstract": "This paper describes a synthesis and tuning procedure of discrete-time, energy-based regulators for port-Hamiltonian systems. Based on a discrete-time approximation of the plant, the control system is designed within the energy-shaping plus damping injection paradigm. This approach guarantees asymptotic stability, but it is not able “as is” to meet other requirements, such as task performance optimisation. The contribution is integrating the power of artificial neural networks as parametric function approximators and passivity-based control to enhance the performance of an asymptotically stable controlled system. The idea is to employ artificial neural networks that are optimally shaped to enhance the performances during task execution through the solution of an optimisation problem.",

      "abstract": "This paper investigates power-balanced descriptions of the conservative vibrating string. First, the hypotheses of continuum mechanics are recalled for the case of infinitesimal transformations. The string is described by classical partial differential equations (PDEs) and reformulated as a port Hamiltonian system (PHS). Second, the case of finite (possibly large) transformations is considered, for which the time variation of the elastic energy appears to be no longer the elastic power. To naturally solve this difficulty and ensure the invariance of the elastic power with respect to the superposition of rigid body motion, the problem is here addressed in the framework of a time-space formulation. Eulerian and Lagrangian conservative formulations are proposed in the context of non relativistic velocities. This work also yields perspectives for a time-space representation of a port-Hamiltonian vibrating string invariant to the change of observer in a relativistic context.",

      "abstract": "Voice production results from the interaction between expelled airflow and soft tissues in the larynx and the vocal tract. Among the large literature on this topic over the last fifty years, a few nonlinear fluid-structure interaction models have been proposed in the port-Hamiltonian framework for passivity purposes. In this paper, we examine, compare and discuss two lumped-element port-Hamiltonian models from the literature, both derived from distributed parameter descriptions and simplifying assumptions chosen to integrate the minimal relevant phenomena involved in the larynx (for self-oscillations) or the vocal tract (during articulation). These models are recalled and reformulated using common terminology and notations. This leads to equivalent circuit representations, the components and the structure of which allow direct comparison (about causality, dimension, nonlinear laws, coupling) and physical interpretation. These results highlight important properties to consider and provide guidelines for future modelling improvement to be used in simulation.",

      "abstract": "This paper addresses linear propagation in an acoustic pipe with a porous wall, a common scenario in wooden wind instruments. First, a scale separation technique is proposed for dissipative propagation within the wall: the material is modelled as a periodic assembly of identical microscopic cells, forming a network of channels filled with air. It is shown that the resulting PDE admits a port-Hamiltonian formulation, of which the state, flow, effort, Hamiltonian, and Differential connection operator are structured using powers of the scale parameter. The resulting macroscopic description, derived from the governing equations at the two lowest orders, manifests as a constrained port-Hamiltonian system involving a Lagrange multiplier. As an example, using an academic cell geometry, we determine the effective wavenumber and dissipation coefficient of a straight tube with a porous wall.",

Starting with the intuitive understanding that port-Hamiltonian systems are “in between” certain closed Hamiltonian systems, the geometric structure of port-Hamiltonian systems must be “in between” the geometric structures of the latter systems. These are Courant algebroids; and hence the geometric structures should be related by Courant algebroid morphisms. Using this idea, we propose a definition of an intrinsic geometric structure and show that it is unique, if it exists.",

This Distributed Parameter System (DPS) has non-collocated boundary control and observation, and reveals a scattering-energy preserving structure. We show that the discretized model preserves the aforementioned structure from the original infinite-dimensional system. Moreover, we analyse the case of moving meshes for the one-dimensional case. The moving mesh requires less states than the fixed one to produce solutions with a comparable accuracy, and it can also reduce the overshoot and oscillations of Gibbs phenomenon produced when using the FEM. Numerical simulations are provided for the case of a one-dimensional transport equation with fixed and moving meshes.",

In various applications, the Hamiltonian density can depend on spatial derivatives of the state such that these systems can not straightforwardly be formulated as boundary port-Hamiltonian system using a Stokes-Dirac structure. In this work, we show that any Hamiltonian system of the above class can be reformulated as a Hamiltonian system on the jet space, in which the Hamiltonian density only depends on the extended state variable itself and not on its derivatives. Consequently, well-known geometric formulations with Stokes-Dirac structures are applicable. Additionally, we provide a similar result for dissipative systems. We illustrate the developed theory by means of the the Boussinesq equation, the dynamics of an elastic rod and the Allen-Cahn equation.",

The model is suitable for representing the behavior of rubber like beams within the range of moderate deformations and rotations.

However, the introduction of white noise into the dynamics causes the model to exhibit divergence. In response, we add a relaxation term that draws the agents’ speed to a desired constant speed and plays the role of the input in the port-Hamiltonian framework. Our results show that this relaxation term effectively stabilises the dynamics even in the presence of stochastic noise.",

Here, we study the equivalent port-Hamiltonian representations of two systems with damping, written using either a classical Hamiltonian or a Stokes-Lagrange subspace. Then, we study the Timoshenko beam and Euler-Bernoulli models, the latter being the flow-constrained version of the former, and show how they can be written using either a Stokes-Dirac or Stokes-Lagrange subspace related by a transformation operator. Finally, it is proven that these transformations commute with the flow-constraint projection operator.",

The proposed approach entails replacing the sheet dynamics that limit deformation in a low-scale model with those derived from a large-scale discretized beam model. By making a few additional assumptions compared to the original low-scale HASEL model, the resulting interconnected system is established by aligning the states of the mechanical component in the low-scale model with those of the large-scale beam model in a straightforward manner. To validate the effectiveness of the methodology, simulated examples are provided along with a comparison to experimental results.",

Using the language of category theory, we identify systems with their behavioural representation and view a port-control structure with desired structural properties on a given closed system as an extension of this system which itself may be embedded in a “larger” closed system. The latter system describes the nature of the ports (e.g. Hamiltonian, metriplectic etc.). This point of view allows us to describe meaningful port-control structures for a large family of systems, which is illustrated with Hamiltonian and metriplectic systems.",

This class includes in particular the Euler-Bernoulli beam equations and more generally 1D linear infinite-dimensional port-Hamiltonian systems with boundary control and observation as well as coupled systems. It is known, that for the Timoshenko beam models internal well-posedness implies well-posedness of the overall system. By means of an example we show that this is not true for the Euler-Bernoulli beam models. An easy verifiable equivalent condition for well-posedness of the overall system will be presented. We will conclude the paper by applying the obtained results to several Euler-Bernoulli beam models.",

      "abstract": "This paper addresses the port-Hamiltonian modeling of the Rayleigh beam, which bridges the gap between the Euler-Bernoulli and Timoshenko beam theories. This balance makes the Rayleigh model particularly suitable for scenarios where Euler-Bernoulli assumptions are insufficient, but Timoshenko’s complexity is unnecessary, such as in cases of moderate oscillations. The originality of the approach lies in deriving the Rayleigh beam model from the displacement field of the Timoshenko beam and incorporating an algebraic constraint consistent with Rayleigh beam theory. The resulting model is formulated as an infinite-dimensional port-Hamiltonian differential-algebraic equation (PH-DAE). A structure-preserving spatial discretization strategy is developed using the mixed finite element method, ensuring the preservation of the PH-DAE structure in the finite-dimensional setting. Numerical simulations demonstrate the accuracy and effectiveness of the proposed model and discretization approach.",

The model of the floating turbine includes the rigid body rotations of the floating platform, maintaining the small deformation approximation for the beam. The port-Hamiltonian approach is used for its modularity and to reflect the system’s passivity. Simulations using a simplified water-structure interaction modelled by Archimedes’ forces on a rectangular platform are given. Leveraging system modularity, control alternatives are discussed.",

The dynamics of the piezo tube actuator are represented by a finite-dimensional system, while the optical fiber is represented by an infinite-dimensional one. Additionally, the actuator and optical fiber are interconnected in a power-preserving manner. A control method for output regulation is proposed for the interconnected system, utilizing the internal model principle. The stability analysis of the closed-loop systems is also investigated. The proposed control method is validated through numerical simulations, demonstrating its effectiveness.",

      "abstract": "An inversion-based approach for the Euler-Bernoulli beam modeled in terms of a boundary controlled port-Hamiltonian system is presented. The goal is to achieve an open-loop finite-time transition between steady states. Exchanging the systems input by a new (fictitious) boundary condition in terms of a so-called basic output located at the boundary or inside the spatial domain, the port-Hamiltonian system is reformulated as a boundary value problem in the spatial domain. Input solution samples are numerically calculated with an inverse Laplace transformation or Fast Fourier Transformation algorithm by assigning a suitable desired trajectory for the basic output. The presented solution approach is evaluated by numerical calculations and simulations.",

Expanding upon previous work on low-scale models, this study adapts the control strategy to large-scale systems, ensuring its effectiveness across scales. The proposed control law retains its structure from the low-scale case, with dimensionality remaining constant despite the increased system complexity. As in the low-scale setting, the closed-loop system mitigates the drift. Numerical simulations confirm the methodology’s effectiveness, demonstrating its capability to achieve precise position control and mitigate drift in large-scale systems.",

We opt for the port-Hamiltonian framework for the representation due to its innate capability of structure-preservation for power-preserving interconnections.

Based on the physical discretization, we then validate the applicability of models of different orders on an example of cantilever beam. We also propose a port-Hamiltonian structure-preserving generalized balanced truncation approach for further reduction of the order.",

      "abstract": "This paper proposes a robust dissipative boundary control for a system described by a 2-D Navier–Stokes equation with polytopic uncertainties under the port-Hamiltonian formulation. The goal of the controller is to obtain a fluid behavior that suppresses the vorticity of the waves. A complete robustness analysis, including both robust stability and robust performance, is presented. Additionally, a topological analysis of the polytopic uncertainties is performed to elucidate the open-loop system behavior. Meanwhile, the dissipative boundary-based controller is obtained by selecting an appropriate storage function. As a case study application, a wave tank is used to illustrate the approach proposed in the paper.",

This new configuration is based on a wound-rotor synchronous generator (WRSM) and a doubly-fed induction machine (DFIM). The energy-based model of the whole system is obtained taking advantage of the capabilities of the port-based modeling techniques. From the dq port-controlled Hamiltonian description of the WRSM and DFIM, the Hamiltonian model of the proposed Direct Synchronous-Asynchronous Conversion System (DiSAC) is developed. Subsequently, the bond graph models of the DiSAC and associate systems are also provided. Numerical simulations are also presented in order to validate the proposed system.",

The controller is designed in order to inject all the generated power into the grid, while the reactive power can be controlled to meet the power system requirements. The system is represented through its port controlled Hamiltonian model, and the controller is designed by interconnection and damping assignment. This design method allows an intuitive way to remove the undesired couplings between system dynamics while assigning the damping required to achieve the expected convergence rate. The proposed controller allows a direct control of the DC link voltage by proper selection of the controller parameters. Moreover, an integral action is added to the proposed controller in order to eliminate the steady-state error in the system variables. The proposal is validated through simulation tests performed using a realistic converter model.",

      "abstract": "In this paper a new nonlinear regulation for synchronous generator excitation control is presented. This method comprises the nonlinear Interconnection and Damping Assignment (IDA) method together with the generator voltage feedback giving a nonlinear Automatic Voltage Regulator (AVR). First, the IDA excitation control is introduced in the third order salient pole synchronous generator mathematical model represented as a Port Controlled Hamiltonian (PCH) system. Thereafter, a generator voltage feedback signal is added. It is proven that adding the feedback to IDA control preserves a PCH structure of a system and the system is therefore passive. In the paper it is also proven that the gained system is stable and that the reference operating point corresponds to the minimal energy point of the system. Finally, the gained IDA AVR is tested with seventh order synchronous generator model and compared to classical generator excitation controllers. The simulations show the efficient tracking of generator voltage reference value, as well as the maintenance of stability in case of grid-side short-circuit occurrence. The main advantages of the proposed controller are efficiently generator voltage tracking and attenuation of electromechanical oscillations in case of a large disturbance, such as grid-side short-circuit.",

      "abstract": "This paper proposes a direct power control (DPC) for a high-voltage direct-current system using voltage source converters (VSC-HVDC) by applying passivity-based control theory. This system allows doing an efficient and reliable integration of electrical network from renewable energy sources. The DPC model permits instantaneous control of the active and reactive power without employing the conventional inner-loop current regulator and the phase-locked loop, thus diminishing investment costs and increasing the reliability of the system. The proportional-integral passivity-based control (PI-PBC) is chosen to control the direct power model of the VSC-HVDC system since this system exhibits a port-Hamiltonian formulation in open-loop and as PI-PBC can exploit this formulation to design a PI controller, which guarantees asymptotically stable in closed-loop based on Lyapunov’s theory. Passivity-based control is an active research subject in the control community which has gained a reputation of being a very theoretical subject. Nevertheless, it can have advantages from a practical point of view including an implementation similar to the conventional controls for power systems applications. The paper is oriented to the power & energy systems community, taking into account this practical approach. The proposed controller is assessed by simulations in a two-terminal VSC-HVDC system and compared with a PI direct power controller. Four simulation conditions using MATLAB/SIMULINK were conducted to verify the effectiveness of PI-PBC against a PI controller and a perturbation observer-based adaptive passive control under various operating conditions.",

      "abstract": "This paper considers a discrete-time scheduling method for the power balancing of a continuous-time DC microgrid system. A high-order dynamics and a resistor network are used for modelling the electrical storage unit and the DC bus of the centralized microgrid system, respectively. A PH (Port-Hamiltonian) formulation on graphs is employed to explicitly describe the microgrid topology. This modelling approach allows us to derive a discrete-time model which preserves the power and energy balance of the physical system. Next, a constrained economic MPC (Model Predictive Control) using the proposed control model is formulated for efficiently managing the microgrid operation. The systematic combination of the network modelling method and optimization-based control allows us to generate the appropriate power profiles. Finally, the benefits of the proposed approach are validated through simulation and comparison results over a particular DC microgrid elevator system under different scenarios and using real numerical data.",

      "abstract": "This paper deals with the problem of controlling a multi-source system applied in hybrid electrical vehicles. The system consists of a proton exchange membrane fuel cell (PEMFC) and a super capacitor (SC). Fuel cell (FC) provides energy for load as a main power source, and SC helps the system in a load peak or in fast transients. The system is modeled as Port controlled Hamiltonian (PCH), and interconnection and damping assignment passivity based controller (IDA-PBC) is used for a typical hybrid vehicle. The aim is first to support the load power in all circumstances without interruption by combination of FC and SC production, and second to control the DC bus voltage. The purposed system analyzed under standard driving cycle consists of off-load, over-load, and charging conditions of SC. Simulations are accomplished in MATLAB/Simulink software for validation of control strategy and new represented algorithm. The results illustrate that both control method and algorithm can manage power among PEMFC, SC, and the load whereas the DC bus voltage remains near its reference.",

      "abstract": "This paper presents a novel error port-controlled Hamiltonian (EPCH) strategy with adaptive gains for a class of complex nonlinear systems subject to actuator saturation and disturbances. Considering the actuator saturation phenomenon in real complex systems, a new smooth saturation function with hyperbolic tangent is adopted to deal with the limitations between the actuator and the control signal. A nonlinear disturbance observer (NDOB) is utilized to compensate the influence of model parameter uncertain, noise, measurement error, external disturbance and other factors in real complex systems. To enhance the accuracy of position control and tracking control for the target, we propose a novel EPCH strategy, which adopts adaptive gain and variable damping technology in the damping injection link. Finally, the permanent magnet synchronous motor (PMSM) servo system is applied to verify the proposed method. The strategy proposed compared with port-controlled Hamiltonian based on disturbance observer, port-controlled Hamiltonian based on load torque estimator and other methods has better control performances by simulation results.",

      "abstract": "Cable-driven wave motion compensation devices are essential for safe maritime operations, including offshore supply missions and marine engineering tasks. In suspended cable configurations, the dynamic performance is inherently constrained by payload weight, since gravity not only enables force closure but also limits the available control authority. Moreover, the system is constantly subjected to wave-induced disturbances, which exacerbate platform oscillations and further challenge controller robustness. To tackle these issues, a novel passivity-based control approach is proposed in this paper that integrates fast terminal sliding mode control with adaptive damping modulation. Specifically, a port-Hamiltonian sliding mode control framework is established to ensure finite-time convergence under energy dissipation constraints, while a bimodal damping modulation strategy is introduced to dynamically regulate system damping for balancing convergence rate and vibration suppression. In addition, a cascaded observer is proposed to reconstruct disturbances and mitigate sensor noise. The global stability of the closed-loop system is rigorously established based on Lyapunov analysis. Simulation and experimental results demonstrate that, under comparable force output levels, the proposed controller reduces the Integral of Time-weighted Absolute Error index by 58 % and 55 %, respectively, thereby achieving improved steady-state performance. The robustness of the proposed controller is further confirmed by sea trials.",

      "abstract": "This article focuses on the design of tracking control for chaotic fractional order systems subjected to perturbations in a port-Hamiltonian framework. The fractional order systems of general form are modeled into port-controlled Hamiltonian form. Then, the extended results on the dissipativity, energy balance, and passivity of the fractional order systems are proved and presented in this paper. The port-controlled Hamiltonian form of the fractional order systems are proved to be asymptotically stable via energy balancing concept. Furthermore, a tracking controller is designed for the fractional order port-controlled Hamiltonian form by utilizing the matching conditions of the port-Hamiltonian systems. Stability of the system is established and analyzed explicitly for the closed-loop system with the help of direct Lyapunov method. Finally, an application example is solved with simulation results and discussions to prove the effectiveness of the propounded control design approach.",

      "abstract": "The conventional tracking control of mechanical systems is generally based on the stabilization of error dynamics and most of the results can only guarantee asymptotic tracking of the desired trajectories. Since error dynamics are generally time-varying, it is very difficult to find appropriate Lyapunov functions or control Lyapunov functions to complete stability analysis and controller design. To address this limitation, the novel constructive exponential tracking control method is proposed to mechanical systems by utilizing the Hamiltonian realization and contraction analysis in this paper. Firstly, based on the Hamiltonian realization and use the structural characteristics of port-Hamiltonian systems, the exponential tracking controllers are constructed for fully actuated and under-actuated mechanical systems by combining the pre-feedback with feedback control. The proposed tracking control strategies can be used to discuss fully actuated and under-actuated mechanical systems in a unified framework. Then the exponential decay-rate of tracking controllers and procedure for selecting control parameters for fully actuated and under-actuated mechanical systems are given. Finally, comparative simulations and experiments are carried out to illustrate the effectiveness and robustness of the proposed control strategy.",

      "abstract": "In recent years, propelled by the rapid development of information technology and the Internet, the formation control of multi-agent systems has gradually emerged as a research hotspot. This paper focuses on the formation control problem of multi-agent mechanical systems with port-Hamiltonian (PH) dynamics. Firstly, the formation problem is converted into an optimization problem whose solution meets the formation requirements. Subsequently, in order to guide the closed-loop system to converge to the solution of this optimization problem, we propose two distributed controllers. The first controller is designed for multi-agent systems where the formation output is defined by position. Notably, this controller preserves the PH structure in the closed-loop, which simplifies the selection of candidate Lyapunov functions for proving the asymptotic convergence of the system to the desired formation. To characterize the minimum convergence rate of the closed-loop system, the second controller is proposed. Based on this controller, the exponential stability and the minimum convergence rate of the closed-loop system are provided. Additionally, these controllers only require agents to exchange estimations of the average state with their neighbors, thereby protecting the privacy of their state and value function information. Finally, the effectiveness of these controllers is verified through an application case on nonholonomic wheeled robots.",

      "abstract": "This paper introduces a distributed approach for dynamic formation tracking and formation fault-tolerant control within the port-Hamiltonian energy framework for multi-agent system (MAS) affected by Coulomb friction. The coupling relationships between agents are equivalently modeled as virtual springs, which simulate the interaction forces between agents to reflect the relative positions and motion states of the agents. A distance-based distributed control scheme is designed, to ensure that the formation composed of multiple agents can continuously adjust the direction and size of the formation while achieving target tracking. Additionally, considering the possibility of communication failure due to agent motion faults, a fault-tolerant algorithm based on topological reconstruction is proposed to reconstruct the formation topology after faults. The feasibility of this control method is verified through numerical simulations.",

      "abstract": "This article proposes a soft-event-triggered-based dynamic damping adaptive fuzzy output-constraints error-port Hamiltonian (EPH) control for robot manipulator with model uncertainty. In the controller design, a generalized desired Hamiltonian function, a dynamic damping matrix, and a soft-event-triggered mechanism are primarily developed. Firstly, a generalized desired Hamiltonian function is proposed, which not only reflects the physical properties of the system but also serves as a generalized Lyapunov function for stability analysis under both constrained and unconstrained conditions. The generalized desired Hamiltonian function provides a new framework for output constraint control and analysis of robot manipulator. Secondly, a dynamic damping matrix based on the equivalent damping ratio of a closed-loop system is designed to systematically optimize the tracking performance of the system by adjusting the equivalent damping ratio through dynamic damping. Thirdly, to reduce communication burden and prevent sampling failures caused by excessively large triggered thresholds, a soft-event-triggered controller is designed. In addition, an adaptive fuzzy system and an adaptive disturbance estimation are integrated to compensate for model uncertainty, nominal model inaccuracies and external disturbances. Finally, the effectiveness of the proposed controller is verified by comparative experiments on a robot manipulator platform.",

It is stated as a generalized pseudo-spectral method which performs exact differentiation by using simultaneously several approximation spaces generated by polynomials bases and suitable choices of port-variables. The symplecticity of this spatial reduction method is proved when used for the reduction of both closed and open systems of conservation laws, for any choice of collocation points (i.e. for any polynomial bases). The symplecticity of some more usual collocation schemes is discussed and finally their accuracy on approximation of the spectrum, on the example of the ideal transmission line, is discussed in comparison with the suggested reduction scheme.",

The essential ingredients to achieve this are: (i) a velocity–vorticity formulation in rotational form, (ii) a sequence of function spaces capable of exactly satisfying the divergence free nature of the velocity field, and (iii) a conserving time integrator. Proofs for the exact discrete conservation properties are presented together with numerical test cases on highly irregular triangular grids.",

The resulting numerical discretizations are applied to the linear and nonlinear Schrödinger equations. Some conservative properties of the numerical schemes are investigated and confirmed in the numerical experiments.",

      "abstract": "We devise the first symplectic Hamiltonian hybridizable discontinuous Galerkin (HDG) methods for the acoustic wave equation. We discretize in space by using a Hamiltonian HDG scheme, that is, an HDG method which preserves the Hamiltonian structure of the wave equation, and in time by using symplectic, diagonally implicit and explicit partitioned Runge–Kutta methods. The fundamental feature of the resulting scheme is that the conservation of a discrete energy, which is nothing but a discrete version of the original Hamiltonian, is guaranteed. We present numerical experiments which indicate that the method achieves optimal approximations of order k + 1 in the L 2 -norm when polynomials of degree k ≥ 0 and Runge–Kutta time-marching methods of order k + 1 are used. In addition, by means of post-processing techniques and by increasing the order of the Runge–Kutta method to k + 2 , we obtain superconvergent approximations of order k + 2 in the L 2 -norm for the displacement and the velocity. We also present numerical examples that corroborate that the methods conserve energy and that they compare favorably with dissipative HDG schemes, of similar accuracy properties, for long-time simulations.",

      "abstract": "A mixed mimetic spectral element method is applied to solve the rotating shallow water equations. The mixed method uses the recently developed spectral element histopolation functions, which exactly satisfy the fundamental theorem of calculus with respect to the standard Lagrange basis functions in one dimension. These are used to construct tensor product solution spaces which satisfy the generalized Stokes theorem, as well as the annihilation of the gradient operator by the curl and the curl by the divergence. This allows for the exact conservation of first order moments (mass, vorticity), as well as higher moments (energy, potential enstrophy), subject to the truncation error of the time stepping scheme. The continuity equation is solved in the strong form, such that mass conservation holds point wise, while the momentum equation is solved in the weak form such that vorticity is globally conserved. While mass, vorticity and energy conservation hold for any quadrature rule, potential enstrophy conservation is dependent on exact spatial integration. The method possesses a weak form statement of geostrophic balance due to the compatible nature of the solution spaces and arbitrarily high order spatial error convergence.",

      "abstract": "We present the mixed Galerkin discretization of distributed parameter port-Hamiltonian systems. On the prototypical example of hyperbolic systems of two conservation laws in arbitrary spatial dimension, we derive the main contributions: (i) A weak formulation of the underlying geometric (Stokes–Dirac) structure with a segmented boundary according to the causality of the boundary ports. (ii) The geometric approximation of the Stokes–Dirac structure by a finite-dimensional Dirac structure is realized using a mixed Galerkin approach and power-preserving linear maps, which define minimal discrete power variables. (iii) With a consistent approximation of the Hamiltonian, we obtain finite-dimensional port-Hamiltonian state space models. By the degrees of freedom in the power-preserving maps, the resulting family of structure-preserving schemes allows for trade-offs between centered approximations and upwinding. We illustrate the method on the example of Whitney finite elements on a 2D simplicial triangulation and compare the eigenvalue approximation in 1D with a related approach.",

      "abstract": "A finite-difference spatial discretization scheme that preserves the port-Hamiltonian structure of infinite dimensional systems governed by the wave equation is proposed. The scheme is based on the use of staggered grids for the discretization of different variables of the system. The discretization is given in 2D for rectilinear and regular triangular meshes. The proposed method is completed with the midpoint rule for time integration and numerical results are provided, including considerations for interconnection and closed loop behaviors and isotropy comparison between the proposed meshes.",

We show that the new method which is obtained by using both continuous and discontinuous discretisations in space, admits a local and global conservation law of energy. We also show existence and uniqueness of solutions of the discrete equations. Further, we illustrate the error behaviour and the conservation properties of the proposed discretisation in extensive numerical experiments on the linear and nonlinear wave equation and the nonlinear Schrödinger equation.",

      "abstract": "In this paper we propose a novel approach to discretize linear port-Hamiltonian systems while preserving the underlying structure. We present a finite element exterior calculus formulation that is able to mimetically represent conservation laws and cope with mixed open boundary conditions using a single computational mesh. The possibility of including open boundary conditions allows for modular composition of complex multi-physical systems whereas the exterior calculus formulation provides a coordinate-free treatment. Our approach relies on a dual-field representation of the physical system that is redundant at the continuous level but eliminates the need of mimicking the Hodge star operator at the discrete level. By considering the Stokes-Dirac structure representing the system together with its adjoint, which embeds the metric information directly in the codifferential, the need for an explicit discrete Hodge star is avoided altogether. By imposing the boundary conditions in a strong manner, the power balance characterizing the Stokes-Dirac structure is then retrieved at the discrete level via symplectic Runge-Kutta integrators based on Gauss-Legendre collocation points. Numerical experiments validate the convergence of the method and the conservation properties in terms of energy balance both for the wave and Maxwell equations in a three dimensional domain. For the latter example, the magnetic and electric fields preserve their divergence free nature at the discrete level.",

      "abstract": "Friedrichs' systems (FS) are symmetric positive linear systems of first-order partial differential equations (PDEs), which provide a unified framework for describing various elliptic, parabolic and hyperbolic semi-linear PDEs such as the linearized Euler equations of gas dynamics, the equations of compressible linear elasticity and the Dirac-Klein-Gordon system. FS were studied to approximate PDEs of mixed elliptic and hyperbolic type in the same domain. For this and other reasons, the discontinuous Galerkin method (DGM) represents the most common and versatile choice of approximation space for FS in the literature. We implement a distributed memory solver for stationary FS in deal.II. Our focus is model order reduction. Since FS model hyperbolic PDEs, they often suffer from a slow Kolmogorov n-width decay. We develop and combine two approaches to tackle this problem in the context of large-scale applications. The first is domain decomposable reduced-order models (DD-ROMs). We will show that the DGM offers a natural formulation of DD-ROMs, in particular regarding interface penalties, compared to the continuous finite element method. We also develop new repartitioning strategies to obtain more efficient local approximations of the solution manifold. The second approach involves shallow graph neural networks used to infer the limit of a succession of projection-based linear ROMs corresponding to lower viscosity constants: the heuristic behind concerns the development of a multi-fidelity super-resolution paradigm to mimic the mathematical convergence to vanishing viscosity solutions while exploiting to the most interpretable and certified projection-based DD-ROMs.",

      "abstract": "We study the structure-preserving space discretization of port-Hamiltonian (pH) systems defined with differential constitutive relations. Using the concept of Stokes-Lagrange structure to describe these relations, these are reduced to a finite-dimensional Lagrange subspace of a pH system thanks to a structure-preserving Finite Element Method. To illustrate our results, the 1D nanorod case and the shear beam model are considered, which are given by differential and implicit constitutive relations for which a Stokes-Lagrange structure along with boundary energy ports naturally occur. Then, these results are extended to the nonlinear 2D incompressible Navier-Stokes equations written in a vorticity–stream function formulation. It is first recast as a pH system defined with a Stokes-Lagrange structure along with a modulated Stokes-Dirac structure. A careful structure-preserving space discretization is then performed, leading to a finite-dimensional pH system. Theoretical and numerical results show that both enstrophy and kinetic energy evolutions are preserved both at the semi-discrete and fully-discrete levels.",

      "abstract": "In this article we study port-Hamiltonian partial differential equations on certain one-dimensional manifolds. We classify those boundary conditions that give rise to contraction semigroups. As an application we study port-Hamiltonian operators on networks whose edges can have finite or infinite length. In particular, we discuss possibly infinite networks in which the edge lengths can accumulate zero and port-Hamiltonian operators with Hamiltonians that neither are bounded nor bounded away from zero. We achieve this, by first providing a new description for maximal dissipative extensions of skew-symmetric operators. The main technical tool used for this is the notion of boundary systems. The latter generalizes the classical notion of boundary triple(t)s and allows to treat skew-symmetric operators with unequal deficiency indices. In order to deal with fairly general variable coefficients, we develop a theory of possibly unbounded, non-negative, injective weights on an abstract Hilbert space.",

      "abstract": "For an ideal transmission line described by the telegrapher's equations, a mixed finite element method-an extension of widely used spatially discretized approach-has been introduced. This numerical approximation approach maintains both the Dirac structure and passivity, guaranteeing that the spatially discretized system preserves its port-Hamiltonian characteristics. In this paper, we employ this method to spatially discretize two infinite-dimensional port-Hamiltonian systems characterized by variable coefficients and boundary controls. Subsequently, we explore the preservation of exponential stability in the resulting semi-discretized systems, establishing their uniform exponential stability concerning discretization parameters. Through frequency domain analysis, uniform exponential stability is demonstrated for both semi-discretized models. Finally, numerical simulations confirm the efficacy of this semi-discrete approach.",

Using the concept of a hypocoercivity index, quantitative estimates on the short-time and long-time decay behavior of a hypocoercive system are derived. As a useful tool for analyzing the structural properties, an infinite-dimensional staircase form is also derived and connections to linear systems and control theory are presented. Several examples illustrate the new concepts and the results are applied to the Lorentz kinetic equation.",

      "abstract": "This work is motivated by an aeronautical issue: the fuel sloshing in the tank coupled with very flexible wings. Vibrations due to these coupled phenomena can lead to problems like reduced passenger comfort and maneuverability, and even unstable behavior. Port-Hamiltonian systems (pHs) provide a unified framework for the description of multi-domain, complex physical systems and a modular approach for the interconnection of subsystems. In this work, pHs models are proposed for the equations of liquid sloshing in moving containers and for the structural equations of beams with piezoelectric actuators. The interconnection ports are used to couple the sloshing dynamics in the moving tank to the motion the beam. This coupling leads to an infinite-dimensional model of the system in the pHs form. A finite-dimensional approximation is obtained by using a geometric pseudo-spectral method that preserves the pHs structure at the discrete level. Experimental tests on a structure made of a beam and a tank were carried out to validate the finite-dimensional model of liquid sloshing in moving containers. Finally, the pHs model proves useful to design an active control law for the reduction of sloshing phenomena.",

This paper aims at providing a fundamental theory for proving the effectiveness of this procedure. The class of problem that the procedure can deal with has been extended. Its application was formerly restricted to linear time invariant siso system. The systems considered now are linear time invariant mimo systems. The optimization objective is the minimization of dissipation and input. The developments concerning the optimal control problem are based on the Pontryagin maximum principle and the proof of the effectiveness of the procedure makes a broad use of the port-Hamiltonian concept. As a result, the bond graph representation of the given optimization problem enables the analytical system, which provides the optimal solution, to be derived. The work presented in this paper is the first step in research with perspectives towards formulating dynamic optimization problems in bond graph and, towards coupling this formulation with a sizing methodology using bond graph language and a state-space inverse model approach. This sizing methodology, however, is not the topic of this paper and thus is not presented here.",

A generalization of Passivity Based Control (PBC) is proposed and fitted to bond graph formalism. The state equations of the equivalent average model are first deduced from the original bond graph using the notion of commutation cells and then interpreted according to Port Controlled Hamiltonian formalism. The whole approach is presented in a formal way. This method is then applied on a multicellular serial converter, which is widespread in power systems and of growing interest. The application of PBC associated to a modelling approach using commutation cells on a non-trivial example shows its efficiency to determine a generic controller, the number of elementary cells being considered as a parameter.",

Once flow, effort, and “power” (i.e., the cash flow) have been defined, the behaviour of these simple elements is provided, and their interconnection is described in terms of Dirac and contact structures. The first ones, associated to power conservation in physical modelling, correspond to the law of good bookkeeping (Walras׳s Law), in economy. Differently, contact structures appear in the description of irreversible phenomena, and in macro-economy they are employed in a more realistic formulation of the firm (or supplier) behaviour. The firm, in fact, is a profit maximising entity that interconnects the markets associated to the demand and to the input factors in order to create a profit. Several examples are provided to show to effectiveness of the approach.",

      "abstract": "In this paper we present a dynamic model of marine vehicles in both body-fixed and inertial momentum coordinates using port-Hamiltonian framework. The dynamics in body-fixed coordinates have a particular structure of the mass matrix that allows the application of passivity-based control design developed for robust energy shaping stabilisation of mechanical systems described in terms of generalised coordinates. As an example of application, we follow this methodology to design a passivity-based controller with integral action for fully actuated vehicles in six degrees of freedom that tracks time-varying references and rejects disturbances. We illustrate the performance of this controller in a simulation example of an open-frame unmanned underwater vehicle subject to both constant and time-varying disturbances. We also describe a momentum transformation that allows an alternative model representation of marine craft dynamics that resembles general port-Hamiltonian mechanical systems with a coordinate dependent mass matrix.",

To overcome those defects, a new energy-shaped method based on the cyclo-passivity is proposed to avoid solving partial differential equations. Due to the proposed method, the exponential stability of Port-Hamiltonian has been worked out. Besides that, a relationship between the guaranteed cost control and dissipation is established for the Port-Hamiltonian system, which presents an explicit form of dissipative energy. At last, examples show the validity of the proposed contents.",

      "abstract": "This paper is concerned with the problems of simultaneous stabilization and set-point output regulation of N Port-Hamiltonian (PH) systems. First, incremental models of PH systems are constructed and the passivity of incremental systems is established with some reasonable assumptions. Then a proportional plus integral (PI) controller is proposed to simultaneously stabilize incremental systems, and the stability of the closed-loop system is proved by Lyapunov function approach. The simple case with two PH systems is studied emphatically, and the obtained results are also naturally extended to the general case of N PH systems. Finally, the validity and applicability of the proposed PI controller is verified through an illustrative example.",

For unforced SPCH systems, via energy-based multiple Lyapunov functions methods, sufficient conditions of both exponential stability and asymptotical stability are obtained under arbitrary switching signals with an average dwell time scheme. Then, based on the state feedback, a switching controller is designed to stabilize SPCH systems, and a switching H ∞ controller is presented to attenuate the external disturbances for SPCH systems, while SPCH systems are subject to actuator saturation, the stabilization and H ∞ control are investigated and the truncation-inequality method is employed to deal with the saturation. Finally, two numerical simulation examples are provided to verify the effectiveness of the proposed methods.",

      "abstract": "In motor system control design, a single controller is usually employed to simultaneously control two or more motors for saving costs, which also achieves the computational simplification of control. In practical Hamiltonian systems control, more systems also need to be stabilized by a single controller under some working conditions. Thus, this paper studies simultaneous stabilization problem of two nonlinear Port-controlled Hamiltonian (PCH) systems with disturbances by a composite controller. Based on the Hamiltonian structure properties, two PCH systems are combined together to generate an augmented PCH system by utilizing output feedbacks firstly. Then, to estimate disturbances effectively, it is essential to design a nonlinear disturbance observer (NDOB) and the estimate is employed to feedforward compensate the effects of disturbances. Next, combining the output feedback part and the disturbance compensation part together, a simultaneous stabilization controller is developed. Subsequently, it is proved that the closed-loop system under the proposed controller is asymptotically stable. Finally, an example with simulations reveals that the proposed method is effective.",

      "abstract": "This paper investigates the finite-time stability (FTS) and finite-time stabilization for a class of nonlinear singular time-delay Hamiltonian systems, and proposes a number of new results on these issues. Firstly, an equivalent form is obtained for the nonlinear singular time-delay Hamiltonian systems by the singular matrix decomposition method, based on which some delay-independent and delay-dependent conditions on the FTS are derived for the systems by constructing a kind of novel Lyapunov function. Secondly, we use the equivalent form as well as the energy shaping plus damping injection technique to investigate the finite-time stabilization problem for a class of nonlinear singular port-controlled Hamiltonian (PCH) systems with time delay, and present a specific control design procedure for the systems. Finally, we give several illustrative examples to show the effectiveness of the results obtained in this paper.",

      "abstract": "This paper addresses the problems of finite-time stabilization and H ∞ control for a class of switched port-controlled Hamiltonian (SPCH) systems with actuator saturation (AS). By the energy-based multiple Lyapunov functions (MLFs) method and the mode-dependent average dwell time (MDADT) technique, finite-time stability criterion for unforced SPCH systems with all modes finite-time stable is derived. Further, state feedback strategies and truncation inequality technique are employed to achieve finite-time stabilization of SPCH systems with AS, where each unforced subsystem may be finite-time unstable. Besides, a switching state feedback controller is developed to attenuate the external disturbances for SPCH systems with AS and external disturbances, and new criterion is presented to solve the finite-time H ∞ control problem for the augmented system. Finally, numerical examples are provided to show the effectiveness of the proposed methods.",

      "abstract": "This paper considers the group output consensus problem for a class of disturbed port-controlled Hamiltonian multi-agent systems via a composite control method. The composite distributed control protocol is proposed by combining the damping injection and energy shaping method, the finite-time disturbance observer (FTDO) technique and distributed protocol, which makes the closed-loop Hamiltonian multi-agent systems asymptotically stable and the group outputs reach consensus. It is shown that many kinds of disturbances can be estimated accurately via the FTDO. The advantage is that this control scheme exhibits not only better robustness against disturbances, but also the nominal system recovery performance. Two illustrative examples reveal that the designed control protocol is effective.",

      "abstract": "This paper is concerned with the simultaneous exponential stabilization problem for a set of stochastic port-controlled Hamiltonian (PCH) systems. Due to the limited bandwidth of the channels, the phenomena of fading channels and transmission delays which are described by a time-varying stochastic model always occur in the communication channels from the controller to the actuator. Meanwhile, actuator saturation constraint is taken into account. On the basis of dissipative Hamiltonian structural and saturating actuator properties, those stochastic PCH systems are combined to generate an augmented system. By utilizing the stochastic analysis theory, sufficient criterions are given for the simultaneous stabilization controller design ensuring that the closed-loop system is simultaneously exponentially mean-square stable (SEMSS). For the case that there exist external disturbances in the systems, some results on stability analysis and controller design are given. The developed controller design scheme is proved by a three-helicopter model simulation example.",

First, a NN super twisting sliding mode control method is developed for system with unknown external disturbances and uncertain parameters, where NN is adopted to approximate unknown control gain, the disturbance observer (DOB) is employed to estimate the unknown lumped disturbance. The dynamic performance of the control system is enhanced. Second, the EPH control method based on DOB is developed to increase the accuracy of the control system. Lastly, NN super twisting sliding mode and EPH methods-based cooperative control strategy is developed, the superiority of the proposed method is verified through the simulation and experiments.",

      "abstract": "Finite-time design is not common in classical controllers, and the ones in the literature are not usually robust. The state-dependent differential Riccati equation (SDDRE) is an optimal nonlinear design in the company of a finite-horizon cost function that manipulates the terminal time using a weighting matrix of states. This method is sensitive to parametric model uncertainty, though its finite time characteristics can be augmented with other controllers. Port-controlled Hamiltonian (PCH) design can present a robust control law by defining the desired inertia matrix in the reference Hamiltonian function. The PCH is not finite-time; however, it can be modified using the suboptimal gain of the SDDRE controller. This paper combines the SDDRE and the PCH design to present a novel nonlinear controller with both finite-time and robust behavior toward parameter uncertainty in modeling. The finite-time behavior refers to the capability of controlling a system with different final times, as the input parameter to the system (or finishing a control task in a predefined time). The analytical stability proof of the proposed input law has been addressed using Lyapunov’s second method. The modified PCH is applied to second-order dynamical systems; as an illustrative example, a two-degree-of-freedom (DoF) inverted pendulum has been simulated and compared with a proportional–derivative (PD) control and a PCH with constant PD gains. A four-DoF robot arm was also simulated to highlight the application of the proposed method on complex systems. The introduced method outperformed the classical ones and showed finite-time regulation with different terminal times.",

A new passivity-preserving controller design that includes two dynamic extensions for disturbance rejection purposes is presented. The new controller is compared with the corresponding port-controlled Hamiltonian implementation, and an interpretation of the dynamic extensions as low-pass filters is proposed. The effectiveness of the proposed controller is demonstrated with numerical simulations.",

      "abstract": "Recently, the aggregative game in cyber-physical systems has gained significant attention from researchers. In this work, we employ the port Hamiltonian (PH) framework to model the multi-agent systems, providing an accurate representation of the physical dynamics for each player (agent). Then, taking into account the impact imposed by the physical dynamics of the multi-agent systems, we investigate the Nash equilibrium seeking problem of the aggregative game with two types of state-dependent cost functions. Next, two distributed Nash equilibrium seeking algorithms are proposed for aggregative games with these cost functions, respectively. Furthermore, we demonstrate that the multi-agent systems with the proposed distributed algorithm exponentially converge to the Nash equilibrium of the aggregative game with the corresponding cost function. Finally, two simulation examples are provided to show the effectiveness of the proposed algorithms.",

      "abstract": "For a class of Port-controlled Hamiltonian systems with nonvanishing disturbances, this paper investigates its disturbance rejection and stabilization problems via two kinds of sliding-mode control (SMC) approaches. Firstly, a new framework is developed to construct the integral sliding surface, which is dependent on the structure of the Hamiltonian system, and then a SMC law is developed to asymptotically stabilize the Hamiltonian system with better disturbance rejection capability. Secondly, in order to further reduce the chattering phenomenon and maintain the system nominal performance, a novel sliding surface is proposed based on the nonlinear disturbance observer (NDOB) and then a disturbance estimation-based SMC law is designed, which can effectively counteract disturbances and make the closed-loop Hamiltonian system asymptotically stable. Finally, a simulation example clarifies the effectiveness of the two SMC approaches, and the superiority of the NDOB-based SMC approach is also illustrated by comparisons.",

      "abstract": "Dirac structures appear naturally in the study of certain classes of physical models described by partial differential equations and they can be regarded as the underlying power conserving structures. We study these structures and their properties from an operator-theoretic point of view. In particular, we find necessary and sufficient conditions for the composition of two Dirac structures to be a Dirac structure and we show that they can be seen as Lagrangian (hyper-maximal neutral) subspaces of Kreĭn spaces. Moreover, special emphasis is laid on Dirac structures associated with operator colligations. It turns out that this class of Dirac structures is linked to boundary triplets and that this class is closed under composition.",

The forward-backward observers-based algorithm is utilized to solve this problem. The formula for calculating the initial value is derived. Moreover, the iterative sequence is also built for any given guess value and it is showed that it strongly converges to initial value. However, because the exponential stabilities of the error systems between the original systems and the forward∖backward observers play important roles in the involved algorithm, the exponential stability of some related system is firstly discussed. Furthermore, combining the theory of port-Hamiltonian system and the finite difference, the semi-discretization scheme of the finite difference with order reduction is given and the uniform exponential stability of the semi-discretization system is verified by the method paralleling to the continuous system. Finally, the convergence analysis of the finite difference scheme is given and the convergence of the solution of the mixed finite element scheme induced by the finite difference scheme with order reduction to the solution of the continuous counterpart is also presented.",

      "abstract": "A high performance non-linear controller that exploits the properties of port-Hamiltonian systems to precisely define the interconnections and energy dissipations of non-linear processes is presented for a large class of chemical processes. The controller is derived from classical interconnection and damping assignment–passivity based control theory but an additional degree of freedom is introduced in the controller design by the use of “non-exact matching” closed-loop storage functions. By a proper closed-loop interconnection assignment the proposed controller achieves total decoupling between outputs and since no inversion of the process dynamics is made in the design it is equally applicable to minimum phase and nonminimum phase system. The controller design methodology is presented and stability conditions are stated. As illustrative example the proposed method is used to design controllers for a multiple-input/multiple-output non-isothermal continued stirred tank reactor that exhibits nonminimum phase behavior.",

      "abstract": "In recent years so-called Port-Hamiltonian systems became popular in the literature. This is mainly due to the passivity properties and the evident system structure of Port-Hamiltonian systems that allow an energy interpretation of this system class. Based on these properties Port-Hamiltonian systems constitute an active research area and several control design methods for Port-Hamiltonian systems have been developed. Especially the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) method has been proven to be very successful. In the application of IDA-PBC and other Port-Hamiltonian system techniques to real-world examples so far mainly electro-mechanical systems have been considered, because for those examples Port-Hamiltonian systems are the standard modeling framework. This paper gives an introduction to the framework of Port-Hamiltonian systems and the IDA-PBC design and shows with different examples that it is also applicable in process control.",

      "abstract": "Abstract This paper proposes a thermodynamical pseudo-Hamiltonian formulation of Continuous Stirred Tank Reactor model in which takes place some chemical reaction. This is done both in the isothermal and non isothermal cases. It is shown that the Gibbs free energy and the opposite of entropy can be chosen as Hamiltonian function respectively. For the non isothermal case, the so-called Interconnection and Damping Assignment Passivity Based Control method is applied to stabilize the system at a desired state. For this general reaction scheme, the control problem is shown to be easy to solve as soon as the closed loop Hamiltonian function is chosen to be proportional to the so-called thermodynamic availability function. Simulation results based on a simple first order reaction and operating conditions leading to multiple steady states of the CSTR are given to validate the proposed control design procedure.",

Using entropic formulation of thermodynamic systems, the construction is applied to a class of thermo-mechanical systems. The proposed approach leads to an explicit expression of the dissipation along the trajectories of the dynamics. The considered thermo-mechanical systems are, in a thermodynamical sense, systems for which the dynamics of the extensive variables are functions of the intensive variables with respect to an entropic formulation. Using the entropy as the storage function, the dissipative structures of an analogue to a port-controlled Hamiltonian (PCH) representation are identified with irreversible phenomena, while the conservative structures are identified with reversible or isentropic phenomena. Examples are presented to illustrate the application of the proposed methodology, including a reacting system.",

It applies to the spatial discretization of systems of conservation laws with boundary energy flows and/or distributed source terms. The symplecticity of the proposed spatial discretization schemes is defined with respect to the natural power pairing (form) used to define the port-Hamiltonian formulation for the considered systems of balance equations. The method is applied to the resistive diffusion model, a parabolic equation describing the plasma dynamics in tokamaks. A symplectic Galerkin scheme with Bessel conjugated bases is derived from the usual Galerkin method, using the proposed method. Besides the spectral and energetic properties expected from the symplecticity of the method, it is shown that more accurate approximation of eigenfunctions and reduced numerical oscillations result from this choice of conjugated approximation bases. Finally, the obtained numerical results are validated against experimental data from the tokamak Tore Supra facility.",

      "abstract": "In this paper, a tracking-error-based control design without feedback passivation stage is developed for the stabilization of physical and chemical nonlinear processes. To achieve control objectives, the system dynamics is first formulated under appropriate conditions as a relaxing (pseudo) port-Hamiltonian (PH) representation with some quadratic storage function, in which the positive semi-definite property of damping matrix may not be taken necessarily into account. Then, a reference trajectory expressed by a certain structure passing through a desired set-point (or containing an optimal profile) is suitably chosen. By adding a relevant damping injection, asymptotic and global convergence of error dynamics is guaranteed. Two case studies including the level control of a four-tank process of continuous time type and the optimal tracking of a batch polymerization reactor of discontinuous time type due to the nature of the process operation are used to illustrate the application and the effectiveness of the approach. Besides the control performance comparison with the conventional passivity-based control method and the robustness evaluation against disturbance and/or noise are included.",

      "abstract": "According to the actual production requirements in process control, this paper proposes an optimized control strategy for the quadruple-tank liquid level system (QTLLS). Firstly, using the Bernoulli’s law and mass conservation principle, the dynamic mathematical model of QTLLS is established and linearized. Secondly, the state error port controlled Hamiltonian (EPCH) controller is designed by Hamiltonian system model construction which utilize the Hamiltonian principle, and a disturbance observer(DOB) is chosen to compensate disturbances impact. Thirdly, a deadbeat model predictive (DBMP) control algorithm with discrete-time disturbance observer (DTDOB) is proposed. Finally, in order to establish an optimized control strategy, an optimized function is proposed, which can give full play to the advantages of DBMP-OB algorithm with fast dynamic response and EPCH-OB algorithm with good steady-state performance. A wealth of results from simulation and experimental fully confirm the superiority of the proposed control strategies compare with proportional–integral–derivative (PID) control and sliding mode control (SMC). Moreover, the proposed optimized control strategy has been realized position control, tracking control and disturbance compensation control in this paper. It meets the needs of production and has great industrial application prospects.",

      "abstract": "In this work we propose a nonlinear passive control approach based on the Port-Hamiltonian framework for a multistage anaerobic digestion (AD) system. The process that we analyze has two coupled bioreactors that treat a high-strength organic wastewater. The model is introduced as a simple mass-balance equations with Monod and Haldane type kinetics. A Gibbs-free-energy-based storage function is first used to characterize the passive behavior of the open-loop process and its internal dissipation mechanisms. For controller synthesis, a separate quadratic Hamiltonian is introduced within the control-oriented IDA-PBC formulation. The controller is designed with the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) method that reshapes the dynamics to follow a desired closed-loop energy profile. In the proposed design, the physical interconnections and biochemical constraints are kept explicit, while the desired operating point is locally stabilized without requiring model inversion. The control input acts on the dilution rate of each reactor. In this way, the main process variables, such as Chemical Oxygen Demand (COD) and Volatile Fatty Acids (VFA), stay close to their reference values, even in the presence of the influent composition perturbations. The performance of the proposed strategy is tested by numerical simulations. The numerical results show satisfactory disturbance rejection and recovery of the steady-state regime under the evaluated operating scenarios. Practical implementation will require online estimation of unmeasured biomass states and suitable computational hardware.",

      "abstract": "This paper deals with the time-domain simulation of an electro-mechanical piano: the Fender Rhodes. A simplified description of this multi-physical system is considered. It is composed of a hammer (nonlinear mechanical component), a cantilever beam (linear damped vibrating component) and a pickup (nonlinear magneto-electronic transducer). The approach is to propose a power-balanced formulation of the complete system, from which a guaranteed-passive simulation is derived to generate physically-based realistic sound synthesis. Theses issues are addressed in four steps. First, a class of Port-Hamiltonian Systems is introduced: these input-to-output systems fulfill a power balance that can be decomposed into conservative, dissipative and source parts. Second, physical models are proposed for each component and are recast in the port-Hamiltonian formulation. In particular, a finite-dimensional model of the cantilever beam is derived, based on a standard modal decomposition applied to the Euler-Bernoulli model. Third, these systems are interconnected, providing a nonlinear finite-dimensional Port-Hamiltonian System of the piano. Fourth, a passive-guaranteed numerical method is proposed. This method is built to preserve the power balance in the discrete-time domain, and more precisely, its decomposition structured into conservative, dissipative and source parts. Finally, simulations are performed for a set of physical parameters, based on empirical but realistic values. They provide a variety of audio signals which are perceptively relevant and qualitatively similar to some signals measured on a real instrument.",

      "abstract": "We study the characterization of several distance problems for linear differential-algebraic systems with dissipative Hamiltonian structure. Since all models are only approximations of reality and data are always inaccurate, it is an important question whether a given model is close to a ‘bad’ model that could be considered as ill-posed or singular. This is usually done by computing a distance to the nearest model with such properties. We will discuss the distance to singularity, the distance to the nearest high index problem, and the distance to instability for dissipative Hamiltonian systems. While for general unstructured differential-algebraic systems the characterization of these distances are partially open problems, we will show that for dissipative Hamiltonian systems and related matrix polynomials there exist explicit characterizations that can be implemented numerically.",

      "abstract": "We present a new balancing-based structure-preserving model reduction technique for linear port-Hamiltonian descriptor systems. The proposed method relies on a modification of a set of two dual generalized algebraic Riccati equations that arise in the context of linear quadratic Gaussian balanced truncation for differential algebraic systems. We derive an a priori error bound with respect to a right coprime factorization of the underlying transfer function thereby allowing for an estimate with respect to the gap metric. We further theoretically and numerically analyze the influence of the Hamiltonian and a change thereof, respectively. With regard to this change of the Hamiltonian, we provide a novel procedure that is based on a recently introduced Kalman–Yakubovich–Popov inequality for descriptor systems. Numerical examples demonstrate how the quality of reduced-order models can significantly be improved by first computing an extremal solution to this inequality.",

      "abstract": "Modern model-based nonlinear control requires a good mathematical description of the system we want to control, for both, the system analysis and the controller design. Obviously, the term nonlinear system is too broad, and one is interested in subclasses of nonlinear systems with at least two properties. These classes should cover real world problems, and there should exist controller design methods, powerful enough to admit a systematic design of the closed loop with certain properties. Now, classical Hamiltonian systems have a rich mathematical structure, which has been extended such that dissipative effects and inputs, outputs, or better ports, are included in this class. This contribution starts with a Hamiltonian description of linear time invariant lumped parameter systems to motivate the introduction of certain mathematical ideas, which will be exploited in the nonlinear case afterwards. After that the approach will be extended to the distributed parameter case. Finally, the applicability of the presented methods is shown with the help of a piezoelectric elastic structure.",

We arrange an associated port-Hamiltonian (pH) formulation of first order for the second-order systems. Each pH system implies a Hamiltonian function describing an internal energy.

      "abstract": "In this paper, a novel dual closed-loop control framework is proposed for trajectory tracking of electro-hydraulic servo systems, utilizing interconnection and damping assignment passivity-based control alongside a finite-time extended state observer. First, a finite-time approach, coupled with an extended state observer, is employed to estimate system model uncertainties and stochastic disturbances, achieving fast finite-time uniformly ultimately bounded stability of observation errors. Second, the nonlinear state–space model is converted into a port-controlled Hamiltonian system with disturbances. Energy shaping and damping injection methods are then applied to transform the port-controlled Hamiltonian model into the desired closed-loop system. Subsequently, the cascade characteristics of the electro-hydraulic servo system are leveraged to establish virtual inputs, facilitating the development of a dual closed-loop interconnection and damping assignment passivity-based controller. The inner-loop controller utilizes spool displacement as an input to mitigate the effects of external disturbances and enhance single-loop control performance, thereby increasing robustness against model uncertainties and external disturbances. Finally, numerical simulations validate the effectiveness and performance of the proposed control strategy in the context of trajectory tracking control for the electro-hydraulic servo system. Compared with FLSMC-MPC and Backstepping-MPC, the proposed controller improve the tracking accuracy by 61.6% and 12.4%, and the velocity tracking performance by 75.7% and 34.2%, respectively.",

      "abstract": "Constant Power Loads (CPLs), which are widely present in DC microgrids, exhibit negative impedance characteristics, reducing the system’s stability margin and posing significant challenges to grid control and stability. To address this issue, we propose an Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) strategy. By reshaping system energy and injecting damping, the proposed controller ensures the attainment of the desired equilibrium point and dynamic performance, thereby enhancing the microgrid’s stability margin. Unlike conventional IDA-PBC methods, which typically modify the interconnection matrix by introducing a parameter K to obtain a unique control law solution, our approach achieves a unique solution by redefining the reference voltage. This strategy effectively eliminates singularity issues at the equilibrium point. Furthermore, we conduct a comprehensive stability analysis of the proposed IDA-PBC, derive the system’s stability margin, and design a trajectory-tracking controller to validate its advantages in improving stability. Finally, numerical simulations and experiments are performed to verify both the effectiveness of the proposed controller and the accuracy of the stability analysis.",

      "abstract": "Interconnection and Damping Assignment (IDA)-Passivity Based Control (PBC) is a promising control method for power converters which can guarantee the large-signal stability of complex modular Microgrids (MG). Passivity can be propagated between passive sub-systems by using the Port Controlled Hamiltonian (PCH) formalism and preserving the natural electrical ports interface for controlled systems. However, the solution based on this approach may cause the apparition of a singular region, leading to certain undesired behaviors. This paper proposes a new control strategy for a boost converter based on IDA-PBC technique, removing the singularities and preserving the closed-loop form used for the proof of passivity. A modified way of computing current reference is introduced and characterized. Experimental validation of the proposed controller is performed using a 3 kW experimental bench with voltage step-up from 200 V to 300 V. The performance of the controller is evaluated in a simulated DC-MG application and compared with a conventional controller. This work evaluates the robustness and dynamics of the proposed controller under variation of the model’s parameters.",

Scaling forces and velocities means scaling the power that is exchanged between master and slave sides through the communication channel. In this paper we show how it is possible to embed power scaling in the scattering based communication channel used in port-Hamiltonian based telemanipulation. Furthermore, a strategy for passively dealing with variable communication delay is proposed in order to allow scaled teleoperation over packet switched networks as Internet.",

The standard approaches used for the control of the port Hamiltonian systems are not applicable to a wide variety of mechatronic systems. This happens, for example, when the input control variable acts directly on some dissipative components of the system. In these cases the controlled devices can only dissipate power and the problem is to find a proper control law in order to meet the control requirements. This paper proposes four control laws for the controlled dissipative components which allow to satisfy a set of control requirements by acting on the energy stored in a subsection of the given system or by controlling the power flowing through a physical section of the system. Although some important issues remain open, the example of the semi-active suspension shows that some positive results can be achieved by applying the proposed approach.",

      "abstract": "This paper deals with the problem of simulating an Ultrasonic Sealing System (USS). The USS is a complex electromechanical system used to seal aseptic packages for liquid foods that is the core of the most advanced filling machines. Since the overall device is the result of the interconnection of several sub-systems that belong to different physical domains, the problem is tackled within the port-Hamiltonian framework, which is naturally multi-domain and multi-scale. On the other hand, the simulation of the whole sealing process is not a trivial task due to the presence of a Compact Transducer (CT) that can be modeled only by means of commercial finite-element software. Then, only extremely high-order models are available, which makes the simulation of the complete system impractical. Consequently, a novel model reduction procedure for port-Hamiltonian systems has been developed. The method is able to preserve the frequency behavior of the original system in a neighborhood of a predefined set of frequencies of interest. In this way, simulation times have been drastically shortened without loosing the essential dynamical information. The reduced order model can be adopted to test the validity of the controller, and to simulate and perform the diagnosis of the entire sealing process. The results of the model reduction algorithm have been experimentally validated. Moreover, also the complete USS model has been derived.",

      "abstract": "Passivity-based control (PBC) is commonly used for the stabilization of port-Hamiltonian (PH) systems. The PH framework is suitable for multi-domain systems, for example mechatronic devices or micro-electro-mechanical systems. Passivity-based control synthesis for PH systems involves solving partial differential equations, which can be cumbersome. Rather than explicitly solving these equations, in our approach the control law is parameterized and the unknown parameter vector is learned using an actor–critic reinforcement learning algorithm. The key advantages of combining learning with PBC are: (i) the complexity of the control design procedure is reduced, (ii) prior knowledge about the system, given in the form of a PH model, speeds up the learning process, (iii) physical meaning can be attributed to the learned control law. In this paper we extended the learning-based PBC method to a regulation problem and present the experimental results for a two-degree-of-freedom manipulator. We show that the learning algorithm is capable of achieving feedback regulation in the presence of model uncertainties.",

Soft continuum manipulators are characterised by high structural compliance which results in a large number of degrees-of-freedom, only a subset of which can be actuated independently or instrumented with sensors. External disturbances, which are common in many applications, result in uncertain dynamics and in uncertain kinematics thus making the control problem particularly challenging. We have investigated the use of integral action to model the uncertain kinematics of the manipulators, and we have designed a new control law to achieve position regulation in Cartesian space by employing a port-Hamiltonian formulation and a passivity-based approach. In addition, we have compared two adaptive laws that compensate the effects of the external disturbances on the system dynamics. Local stability conditions are discussed with a Lyapunov approach and are related to the controller parameters. The performance of the controller is demonstrated by means of simulations and experiments with two different prototypes.",

      "abstract": "This paper addresses the modeling, parameter identification, and validation of curling Hydraulically Amplified Self-healing Electrostatic (HASEL) actuators using the port Hamiltonian (PH) framework. Employing a modular approach, the HASEL actuator is conceptualized as a combination of elementary subsystems. Each subsystem includes electrical and mechanical components. The electrical component is characterized by a variable capacitor in parallel with a resistor branch, which is in series with another capacitor that is also in parallel with a resistor branch, representing charge retention-related drift. The mechanical component consists of linear and torsional springs connected to an equivalent mass. The parameters of the proposed model were identified using the Levenberg–Marquardt optimization algorithm with data from the developed experimental setup. Additional sets of experimental data were used to validate the obtained model.",

      "abstract": "This paper is concerned by the port-Hamiltonian modeling and control of a dielectric elastomer actuator designed for use in a cardiac assist device. The proposed nonlinear model captures the actuator’s hyperelastic material behavior, viscoelastic damping, and electromechanical coupling, and remains valid for large deformations up to 40 %. An original Interconnection and Damping Assignment Passivity-Based Control strategy is developed to achieve closed-loop stabilization at a desired position. The accuracy of the multiphysics model and the performances of the proposed controller are experimentally validated.",

      "abstract": "This paper investigates the control problem for soft continuum manipulators that operate on a plane and that are subject to unknown disturbances. In general, soft continuum manipulators have more degrees-of-freedom than control inputs and are characterised by nonlinear dynamics. Thus, achieving high position accuracy with these systems in the presence of disturbances is a challenging task. In this paper we present the design of a new partial-state feedback controller by using the port-Hamiltonian formulation and we develop a variation of the Integral Interconnection and Damping Assignment Passivity Based Control methodology for a class of soft continuum manipulators. The system dynamics on the bending plane is described by using a rigid-link underactuated model with n elastic virtual joints. The proposed control law regulates the tip rotation to the desired value while compensating unmodelled disturbances and only depends on the tip rotation, which is measurable, hence it is implementable. The effectiveness of the controller is demonstrated with simulations and with experiments on a soft continuum manipulator prototype that employs pneumatic actuation.",

      "abstract": "This paper addresses the robust control problem of mechanical systems with hybrid dynamics in port-Hamiltonian form. It is assumed that only the position states are measurable, and time-delay and saturation constraint affect the control signal. An extended state observer is designed after a coordinate transformation. The effect of the time delay in the control signal is neutralized by applying Padé approximant and augmenting the system states. An assistant system with faster convergence is developed to handle actuators saturation. Fractional-order sliding mode controller acts as a centralized controller and compensates for the undesired effects of unknown external disturbance and parameter uncertainties using the observer estimation results. Stability analysis shows that the closed-loop system states, such as the observer tracking error, and the position/velocity tracking errors, are finite-time stable. Simulation studies on a two ball-playing juggler robot with three degrees of freedom validate the theoretical results’ effectiveness.",

      "abstract": "Clustered tensegrity systems (CTSs) are lightweight, energy-efficient, and modular, making them ideal for engineering applications. The port-Hamiltonian (pH) framework is well-suited for their design and analysis due to its effectiveness in modeling dynamic systems. However, when CTSs are modeled within the pH framework, several challenges arise: (1) Current spatial discretization methods for pH systems are complex and inefficient for CTSs, and cannot directly represent strong nonlinear coupling. (2) Current symplectic time discretization methods for pH systems are inefficient and unstable when solving stiff equations. First, a spatial discretization method based on positional finite element method (PFEM) is proposed. It can accurately capture strong nonlinear coupling from large-scale rotations and deformations without relying on rotation matrices. Then, a stiff problem modification based on symplectic time discretization is proposed. Combined with a Quasi-Newton strategy, it significantly improves computational efficiency with few losses of precision. Numerical simulations show that discrete pH systems based on PFEM can efficiently and accurately capture the energy and dynamic behavior of CTSs. The proposed modification effectively improves stiff problem and significantly enhances computational efficiency.",

These dynamic controllers combine a logical switching architecture with hybrid dynamics to guarantee that the system plant energy is strictly decreasing across switchings. The general framework leads to hybrid closed-loop systems described by impulsive differential equations. Special cases of energy-based hybrid controllers involving state-dependent switching are described, and an illustrative numerical example is given to demonstrate the efficacy of the proposed approach.",

This method is based on a mathematical representation of the dynamic network graph and of its dual graph, using the hybrid incidence matrix, and on a constructive method for analyzing admissible and constrained configurations. The port–Hamiltonian representation associated with the set of hybrid system configurations, parameterized by the discrete state of the switches, is synthesized to be part of the hybrid automaton of the system. This is a further step towards a generic control synthesis for physical switching systems.",

      "abstract": "A parallel simultaneous stabilization of two systems governed by partial differential equation (PDE), with conservation law subject to actuator saturation, is considered, and a method on the control design is proposed. Based on the orthogonal decomposition for a Port-Controlled Hamiltonian system, an  approach to the parallel simultaneous stabilization of two systems governed by partial differential equation, with conservation law subject to actuator saturation, is established. The study shows that the parallel simultaneous stabilization controller obtained in this paper is valid in the case of the systems governed by the PDEs.",

This formulation is an extension to compressible flows of the well-known vorticity–stream function formulation of the incompressible Euler equations. The Hamiltonian and associated Poisson bracket for this new formulation of the compressible Euler equations are derived and extensive use is made of differential forms to highlight the mathematical structure of the equations. In order to deal with domains with boundaries also the Stokes–Dirac structure and the port-Hamiltonian formulation of the Euler equations in density weighted vorticity and dilatation variables are obtained.",

      "abstract": "A modern vehicle can be viewed as a complex cyber–physical system (CPS) where the vehicle dynamics interact with the software control systems. Adaptive cruise control (ACC) and lane keeping control (LKC), in particular, are foundational features for semi-autonomous and autonomous driving. Safety analysis of such systems is extremely important for realizing vehicle autonomy. Ensuring safety in such complex CPS is very challenging, especially in the presence of interactions between multiple subsystems, nonlinearities, hybrid dynamics, and disturbances. This paper presents an approach for safety analysis of automotive control systems using multi-modal port-Hamiltonian systems. The approach uses the Hamiltonian function as a barrier between the energy levels of the safe and unsafe states and employs passivity to prove that trajectories cannot cross this barrier. The approach is applied to the safety analysis of a vehicle dynamics composed with ACC and LKC. The goal is to ensure that the host vehicle will not collide with a lead vehicle and will not skid off of the road. The control design is implemented and evaluated using a hardware-in-the-loop simulation platform. The experimental results demonstrate the safety analysis approach including the impact of implementation effects such as discretization and quantization.",

      "abstract": "In this paper, the stabilization and H ∞ control are considered for switched port-controlled Hamiltonian systems (SPCHSs) with unstabilizable modes via energy-based multiple Lyapunov functions (MLFs) methods and mode-dependent average dwell time (MDADT) strategies, where an improved MDADT-based tradeoff method is developed by a time subsequence technique to govern the running time of the asymptotic stabilization modes and the other ones. Firstly, based on the mode-dependent state feedback controllers, stabilization conditions are derived for SPCHSs with unstabilizable modes under a new MDADT scheme. Secondly, for the case that there are external disturbances for the system, the mode-dependent H ∞ controllers are designed to attenuate external disturbances, besides, H ∞ control conditions are achieved for the system by the energy-based MLFs method with the designed MDADT scheme. Finally, two simulation examples are presented to demonstrate the effectiveness of the proposed methods.",

      "abstract": "Applying jumping locomotion into autonomous mobile robot is an effective way for improving abilities to overcome barriers and pass through complex terrains. In this paper, based on the designed structural framework for bio-inspired quadruped jumping robot, dynamic model is established by utilizing port-Hamiltonian with dissipation (pHd) method, and a passivity-based control strategy for the robot joints trajectory tracking is presented. First, morphology and biomimetics knowledges of frogs (a kind of animals with excellent jumping skill) motivate us to complete a bio-inspired jumping robot framework based on frog’s motion mechanism and body structure with torsional springs as energy storage device. Then, combining system passivity and dissipation, port-Hamiltonian method is utilized to build a dynamic model for expressing the relationship of energy and force in the designed robot. Jumping process analysis of different stages is also designed for ensuring the robot to complete taking-off and landing stages successfully. Next, with the definition of extending feasible robotic joint trajectory by La Salle invariant set principle, interconnection and damping assignment passivity-based control (IDA-PBC) method is exerted to obtain a trajectory controller for realizing smoothly and stably trajectory tracking in joint space. At last, simulation results show the reasonableness of the designed framework. By comparing our method with state-feedback and sliding mode control, effectiveness of the dynamic model and trajectory controller is also verified.",

      "abstract": "In this paper, utilizing energy-based multiple Lyapunov functions (EMLFs) analysis tools, we explore the issues concerning finite-time stabilization and finite-time H ∞ control for switched uncertain nonlinear port-Hamiltonian systems (SUNPHSs) under average dwell time (ADT) restrictions. To solve the impact of uncertain terms and relax the structure of EMLFs, the corresponding constraint conditions are adopted, based on which an improved ADT-based switching scheme is developed, and the sufficient criterion is put forward to ensure the finite-time stability (FTS) of SUNPHSs. Subsequently, a mode-dependent switching state feedback (MDSSF) controller is exploited to render the resulting closed-loop SUNPHSs FTS. Moreover, to attenuate disturbances, another MDSSF controller is presented to keep SUNPHSs possessing finite-time H ∞ performance under a new ADT-based switching scheme. Finally, three simulation examples, including a switched nonlinear circuit system, are provided to substantiate the feasibility of the derived finite-time control approaches.",

      "abstract": "This paper proposes a dual-subsystem cooperative control architecture for a class of affine nonlinear systems. By employing a cooperative weighting function that satisfies the convex combination mechanism, the architecture achieves deep integration of reinforcement learning-based port-Hamiltonian (RL-PH) control and RL-based sliding mode control (RL-SMC). Specifically, the first subsystem aims to enhance steady-state performance. By parameterizing damping injection and additional energy, a reinforcement learning algorithm is adopted to online tune the unknown parameters. This approach not only avoids the complexity of solving the Hamilton–Jacobi–Bellman partial differential equation within the PH framework, but also realizes optimal PH control. The second subsystem focuses on improving transient performance. By constructing a cost function associated with the sliding surface, the conventional SMC is transformed into an optimal control problem, which is approximated by a critic neural network (NN). Furthermore, a nested updating law is meticulously designed to strictly guarantee the asymptotic stability of the NN weight estimation error. Finally, a Gaussian function-based cooperative mechanism is constructed to achieve the seamless fusion of the two control laws. Experimental results demonstrate that the proposed strategy significantly outperforms the standalone RL-PH or RL-SMC methods in terms of both steady-state accuracy and dynamic response speed.",

      "abstract": "This paper presents a motion control system for tracking of attitude and speed of an underactuated slender-hull unmanned underwater vehicle. The feedback control strategy is developed using the Port-Hamiltonian theory. By shaping of the target dynamics (desired dynamic response in closed loop) with particular attention to the target mass matrix, the influence of the unactuated dynamics on the controlled system is suppressed. This results in achievable dynamics independent of stable uncontrolled states. Throughout the design, the insight of the physical phenomena involved is used to propose the desired target dynamics. Integral action is added to the system for robustness and to reject steady disturbances. This is achieved via a change of coordinates that result in input-to-state stable (ISS) target dynamics. As a final step in the design, an anti-windup scheme is implemented to account for limited actuator capacity, namely saturation. The performance of the design is demonstrated through simulation with a high-fidelity model.",

      "abstract": "The paper proposes a general framework to manage a team of Autonomous Underwater Vehicles (AUVs), while keeping the communication constraints, during missions execution. Virtual spring-damper couplings (passive by definition) define the distributed interaction forces between neighbouring vehicles. In this way, through passivity theory, a suitable Lyapunov function for the closed loop system is built to ensure stable convergence of the network vehicles to an equilibrium point, also providing robustness in presence of communication fading and delays, very common in the marine environment. Simulations of typical missions show the effectiveness of the proposed approach. An equivalence between this typical port-Hamiltonian framework and a specific class of potential games, the Bilateral Symmetric Interaction (BSI) one, is also established. Hence, modelling the network with passive elements, it is possible to shape the transient behaviour of the players and the reached equilibria at the end of the game.",

An energy-based model is presented that represents the underactuated submarine in a non-neutrally buoyant state. This model is then used to synthesize a control law using Port-Hamiltonian theory and interconnection and damping assignment passivity-based control. Lyapunov analysis is used to demonstrate stability of the closed-loop system, and a simulation-based study is presented to demonstrate performance of the control law. The results demonstrate that a closed loop non-linear controller is able to improve the quality of emergency rise by automatically compensating for some parasitic effects in the hydrodynamics that can compromise ascent performance.",

The thrust system consists of two propellers which are driven by two electric-powered motors. A hybrid coordination control strategy based on signal and energy method is proposed. The energy controller uses the Port-Controlled Hamiltonian (PCH) control approach, and the signal controller uses the Lyapunov's direct method and backstepping approach. The design of coordination control strategy is used to adjust the strength of the signal controller and energy controller. Simulation results confirm the validity and stability of control algorithm, and the results show that the proposed algorithm can quickly track signals with energy optimization.",

      "abstract": "This paper addresses the tracking control problem of unmanned underwater vehicles under the condition of external disturbances and unmodeled dynamics using Port-Hamiltonian theory. By introducing Port-Hamiltonian theory, conventional UUVs dynamics can be transformed into Port-Hamiltonian form with insightful expressions. Then, combined with a structure preserving adaptive method, unmodeled dynamics and unknown disturbances can be addressed simultaneously without destroying the interconnection structure of the Hamiltonian system. Finally, based on interconnection and damping assignment passivity-based control, the controller is designed in an intuitive way. The dissipation property of Port-Hamiltonian theory is utilized to prove the stability. Compared with other methods that come from the view of signal processing, the proposed scheme has the advantages of better potential and physical interpretation of engineering applications. Simulations and comparisons are conducted to demonstrate the effectiveness of the proposed method.",

Firstly, the three degree of freedoms DP ship model with time delay is transformed into a Port-Controlled Hamiltonian (PCH) one, based on which we design its observer system. Then, by using the augmented technology and the Lyapunov stability theory, several observer-based robust stabilization controllers and observer-based adaptive robust stabilization controllers are designed for the DP ship with time delay, and some delay-independent and delay-dependent robust stabilization results are obtained. Finally, the simulation results show the effectiveness of the observer-based robust stabilization controller proposed in this paper.",

      "abstract": "In this paper, a novel energy-based trajectory tracking control strategy for under-actuated unmanned surface vessels (USVs) in the presence of unknown environmental disturbances is presented. The port-Hamiltonian framework is utilized to propose a passivity-based control model in body-fixed coordinates of the USVs. An adaptive disturbance estimation method is detailed and used to accurately estimate the environmental disturbances affecting USV motion. Furthermore, a passive and Hamiltonian structure-preserving controller is employed to achieve the desired trajectory of the USV system, and the stability of the desired target dynamic system is rigorously proven. The effectiveness of the proposed controller is demonstrated through simulations and experiments on a USV experimental platform, showcasing its capability of trajectory tracking performance and mitigating the effects of disturbances.",

      "abstract": "The fixed-time tracking control schemes of unmanned underwater vehicles (UUVs) are investigated in body-fixed coordinates frame based on Port-Hamiltonian (PH) model with external disturbances. The novel locally and globally fixed-time control laws via the interconnection and damping assignment passivity-based control (IDA-PBC) are designed for trajectory tracking in UUVs. The virtual desired equilibria consisted of the tracking error and the desired trajectory are established by the matching conditions. Moreover, the fixed-time stabilization of the UUV induced of variable parameter matrixes is analyzed. Compared with the traditional IDA-PBC controller, the UUV is guaranteed to achieve the reference trajectory within a fixed time regardless of initial conditions. In the presence of external disturbances, the H ∞ laws are incorporated in the fixed-time control for the UUV, which can ensure faster trajectory tracking and strong anti-disturbance. Finally, the simulation results demonstrate the effectiveness of the main schemes.",

      "abstract": "A novel state error passivity-based cooperative formation controller is proposed for multiple unmanned surface vessels (MUSVs) with complete environments. An energy consumption model is constructed for the MUSVs to elucidate the energy consumption. Firstly, the multiple unmanned surface vessels model is tailored to a new dynamical model as a multiple port Hamiltonian framework. Then, a passivity-based cooperative formation controller is proposed by combining a state error port Hamiltonian controller, an improved leader–follower composite distributed protocol, and a nonlinear disturbances observer. We address the cooperative formation control of multiple USVs by using the port-Hamiltonian framework. Nonlinear disturbances observer is designed to estimate the external disturbances. A smooth function is combined to handle the system input saturation. The controller performances are illustrated by some scenario experiments. The proposed novel controller can archive the cooperative formation of the MUSVs, and effectively improve the integrated system endurance time.",

      "abstract": "Autonomous underwater vehicles (AUVs) are essential to the exploration and utilization of oceanic environments. The development of trajectory tracking control technology has become critical for ensuring precise navigation and efficient task execution by AUVs in marine settings. This paper introduces an adaptive finite-time asymptotic stabilization control method, employing the Hamiltonian approach for AUV trajectory tracking. This method is designed to effectively address time-varying external disturbances and variations in model parameters. By utilizing orthogonal decomposition techniques, the mathematical model for AUV trajectory tracking is transformed into a port-controlled Hamiltonian (PCH) model. Additionally, Hamiltonian control theory is applied to formulate an adaptive finite-time trajectory controller specifically tailored for AUVs. Theoretical analysis, grounded in Lyapunov stability theory, substantiates the adaptive finite-time stability of the closed-loop control system for AUV trajectory tracking. Furthermore, simulation results confirm the efficacy and superiority of the proposed control method, demonstrating reduced tracking errors and accelerated convergence rates in comparison to infinite-time techniques.",

      "abstract": "This paper proposes a novel event-triggered energy-based controller for Unmanned Surface Vessels (USVs) operating in complex scenarios, integrating reinforcement learning techniques with an energy-based framework. Model uncertainties are captured via actor-critic neural networks (NNs), where actor NNs generate control actions and critic NNs assess their performance. To address disturbances, a self-learning nonlinear disturbance observer with an adaptive learning factor is developed, enhancing the accuracy of disturbance estimation. A state-error port-controlled Hamiltonian (PCH) strategy ensures trajectory tracking, complemented by variable damping techniques to optimize the closed-loop system’s dynamic response. The design incorporates event-triggered mechanisms and adaptive control methods to ensure boundedness of all closed-loop signals. Stability analysis demonstrates convergence of the tracking error to a neighborhood of the origin, and simulation results validate the controller’s feasibility and efficacy.",

      "abstract": "This paper proposes a safety-critical cascade control strategy based on the Port-Hamiltonian (PH) framework and Control Barrier Functions (CBFs) to resolve the actuation singularities caused by High-Order CBFs and the Quadratic Program (QP) infeasibility of standard Control Lyapunov Function Control Barrier Function (CLF-CBF) frameworks applied to underactuated surface vehicles (USVs). The outer position loop reformulates the Line-of-Sight (LOS) kinematic error dynamics into a PH structure and utilizes Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) to construct a nominal path-following controller. A kinematic-layer CBF safety filter computes safety-filtered virtual velocity references for the inner-loop, and a passivity-preserving theorem is established within the PH framework. Subsequently, the inner velocity loop integrates IDA-PBC with an H ∞ scheme to track these references and actively attenuate unknown disturbances, compensating for the inherent underactuation of USVs. Comparative simulations across three distinct scenarios validate that the proposed framework effectively suppresses actuator chattering during robust path following and ensures reliable obstacle avoidance capabilities in highly dynamic multi-obstacle environments.",

Compared with other strategies, the rectifier has more dynamic and static performances by using the new strategy. Because of utilizing IDA-PBC to design passivity based controller, the stable state performance and robustness against the load's disturbance of PWM rectifiers are both improved.

Those port-Hamiltonian systems are able to modify their internal structure as well as their interconnection with the environment over time. The framework allows us to prove the First and Second Laws of thermodynamics, but also lets us apply results from optimal and stochastic control theory to physical systems. In particular, we show how to use linear control theory to optimally extract work from a single heat source over a finite time interval in the manner of Maxwell’s demon. Furthermore, the optimal controller is a time-varying port-Hamiltonian system, which can be physically implemented as a variable linear capacitor and transformer. We also use the theory to design a heat engine operating between two heat sources in finite-time Carnot-like cycles of maximum power, and we compare those two heat engines.",

In this paper, we aim at providing an overview of the application of machine learning for port Hamiltonian systems in terms of modelling and control. After an introduction to Port Hamiltonian systems framework, recent results on Hamiltonian systems modelling are presented. Some results on minimal realization and model reduction are then overviewed. Finally, the most important results on the control of Port Hamiltonian systems based machine learning are discussed including adaptive control, iterative control and reinforcement learning. The results presented in this paper are a motivation for the potential of applying machine learning methods to dynamical systems in general and port Hamiltonian systems in particular.",

      "abstract": "Hybrid machine learning based on Hamiltonian formulations has recently been successfully demonstrated for simple mechanical systems, both energy conserving and not energy conserving. We introduce a pseudo-Hamiltonian formulation that is a generalization of the Hamiltonian formulation via the port-Hamiltonian formulation, and show that pseudo-Hamiltonian neural network models can be used to learn external forces acting on a system. We argue that this property is particularly useful when the external forces are state dependent, in which case it is the pseudo-Hamiltonian structure that facilitates the separation of internal and external forces. Numerical results are provided for a forced and damped mass–spring system and a tank system of higher complexity, and a symmetric fourth-order integration scheme is introduced for improved training on sparse and noisy data.",

      "abstract": "Learning dynamical systems through purely data-driven methods is challenging as they do not learn the underlying conservation laws that enable them to correctly generalize. Existing port-Hamiltonian neural network methods have recently been successfully applied for modeling mechanical systems. However, even though these methods are designed on power-balance principles, they usually do not consider power-preserving discretizations and often rely on Runge-Kutta numerical methods. In this work, we propose to use a second-order discrete gradient method embedded in the learning of dynamical systems with port-Hamiltonian neural networks. Numerical results are provided for three systems deliberately selected to span different ranges of dynamical behavior under control: a baseline harmonic oscillator with quadratic energy storage; a Duffing oscillator, with a non-quadratic Hamiltonian offering amplitude-dependent effects; and a self-sustained oscillator, which can stabilize in a controlled limit cycle through the incorporation of a nonlinear dissipation. We show how the use of this discrete gradient method outperforms the performance of a Runge-Kutta method of the same order. Experiments are also carried out to compare two theoretically equivalent port-Hamiltonian systems formulations and to analyze the impact of regularizing the Jacobian of port-Hamiltonian neural networks during training.",

      "abstract": "In this paper, we introduce a framework called ISO-pHNN for identifying nonlinear port-Hamiltonian systems using input-state-output data. The framework utilizes neural networks’ universal approximation capacity to effectively represent complex dynamics in a structured way. We explore different architectures based on MLPs, KANs, and using prior information. The identification technique is validated through examples featuring nonlinearities in either the skew-symmetric terms, the dissipative terms, or the Hamiltonian. We show that incorporating a port-Hamiltonian structure does not lower the accuracy and that using additional prior information improves long-term predictions.",

      "abstract": "Current station keeping strategies target periodic orbits around the unstable Lagrange points. These control strategies are based on the Circular Restricted Three-Body Problem (CRTBP) linearized around an equilibrium point and cannot ensure global stability. In this paper, we use the port-Hamiltonian approach to reformulate the CRTBP with input, which preserves the original nonlinear dynamics. Designing a control strategy based on energy shaping and dissipation injection, we obtain the closed-loop Hamiltonian as the candidate of Lyapunov function, which guarantees asymptotic stability. The control strategy designed here is successfully applied to the stabilization of Lagrange points in CRTBP. Furthermore, the designed control approach shows global stability within the application region of CRTBP model, and it is applicable to set arbitrary equilibrium points. The current framework is also stable against error in the thrust and still works when the third body moves beyond the region of applicability of the linearized dynamics, where the linear controller may fail. Finally, this method has potential to be extended to the three-dimensional CRTBP, where both the perturbation and the thrust out of the plane are considered.",

By means of energy composition of analog circuit, controller AVR and PSS equivalent energy function descriptions are obtained. Then controller energy functions are added to the generator Hamiltonian function, and composed the total energy function of system. Furthermore, a Hamiltonian model of generator integrated AVR and PSS is derived. Finally, according to the dissipative properties of Hamiltonian model, AVR and PSS influences on generator system dissipative properties are analyzed, and PSS damping effect on port is discussed. The results show that damping characteristics reflected in the model are consistent with practical system.",

      "abstract": "The energy management of Hybrid Electric Vehicles (HEV) has witnessed significant academic and industrial attention in recent years. Indeed, the use of different power sources in HEV requires both smart and efficient energy management scheme to split and manage power among them. The energy management strategy should enable continuous supply load balance. In HEVs, the energy management procedure should consider the constraints of load and the different available sources. The fundamental contribution of this paper is the energy management in the HEV in presence of faults in the fuel cell (FC) level while considering battery state of charge constraints. For the flexibility and durability of the proposed energy management scheme, the system mathematical modeling using Port-Controlled Hamiltonian (PCH) approach is developed. Therefore, the Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) is used for a smartly energy management. According to the simulation results, the IDA-PBC is an adequate nonlinear control method that guarantees the stability of the system.",

      "abstract": "This paper presents an adaptive one-step model predictive control (MPC) strategy for optimal load-sharing and voltage regulation in isolated direct current (DC) microgrids. Utilizing a port-Hamiltonian representation within a reduced model, the proposed secondary control method ensures physically consistent actions and incorporates a recursive least-squares algorithm for real-time estimation of the reduced conductance matrix. The one-step formulation enables the analytical derivation of the optimal control law, ensuring convexity and global optimality for real-time implementation. Additionally, a convex optimization procedure is introduced to compute droop control gains, maintaining the passivity properties of the system while balancing current sharing and voltage regulation within operational constraints. Dynamic simulations on a realistic DC microgrid benchmark validate the method’s effectiveness, demonstrating enhancements in load-sharing accuracy, voltage regulation, and responsiveness to abrupt demand changes. These results highlight the potential of the proposed MPC framework to improve the reliability and efficiency of DC microgrid operations.",

      "abstract": "In this paper, disturbance reconstruction and robust trajectory tracking control of biped robots with hybrid dynamics in the port-Hamiltonian form is investigated. A new type of Hamiltonian function is introduced, which ensures the finite-time stability of the closed-loop system. The proposed control system consists of two loops: an inner and an outer loop. A fractional proportional–integral–derivative filter is used to achieve finite-time convergence for position tracking errors at the outer loop. A fractional-order sliding mode controller acts as a centralized controller at the inner-loop, ensuring the finite-time stability of the velocity tracking error. In this loop, the undesired effects of unknown external disturbance and parameter uncertainties are compensated using estimators. Two disturbance estimators are envisioned. The former is designed using fractional calculus. The latter is an adaptive estimator, and it is constructed using the general dynamic of biped robots. Stability analysis shows that the closed-loop system is finite-time stable in both contact-less and impact phases. Simulation studies on three types of biped robots (i.e., two-link walker, RABBIT biped robot, and flat-feet biped robot) demonstrate the proposed controller’s tracking performance and disturbance rejection capability.",

      "abstract": "Robotic systems have evolved to handle various significant interaction tasks in different environments. Under these conditions, the involvement of humans in the environment drastically complicates such interaction tasks; as the safety of humans should be prioritized while seeking to achieve the desired task aim. It is thus paramount that appropriate developments should be pursued with specific considerations for such safety-performance-balanced interaction tasks on unknown soft environments (e.g., humans). Towards this end, we present an adaptive robust, and passive control scheme based on model predictive control and variable impedance control that addresses this challenge. Under this control scheme, during robotic interaction tasks with complex environments (e.g., humans), the presented development and design incorporate safety thresholds that are carefully satisfied via impedance adaptation, and realized by a safety-related mode-switching mechanism. Once the safety thresholds are satisfied, task performance is then focused on. Additionally, a real-time adaptive robust parameter estimator is designed and utilized to estimate the environment contact model for the model predictive control, and thus this control scheme is robust against disturbances (e.g., which would invariably arise from the inevitable small bounded human motions) during the interaction tasks. Finally, the key safety and performance attainments of the proposed control scheme are verified via experiments. The experiments are conducted on two silicone rubber models and a human arm. These show that the proposed control scheme effectively outperformed various currently available control schemes in these interaction tasks with unknown environment contact models, and bounded but unpredictable environment position shifts, such as in robotic ultrasound scanning applications.",

      "abstract": "Thermodynamic system dynamics exhibit strong nonlinearity and high uncertainty. If a simple control law can effectively regulate the thermodynamic systems, it will substantially reduce the complexity of engineering implementation, commissioning, and maintenance. While passivity-based control has been successfully applied to mechanical, electrical, and electromagnetic systems using energy as a storage function, thermodynamic systems require a different approach due to the non-convex characteristics of their internal energy function. This research defines the entropy production metric and proposes the port-Hamilton realization of the thermodynamic system dynamics. By using the second-order difference of entropy production metric as the storage function, the extended-state passivity-based control is proposed. The control leverages the principle of irreversible thermodynamics that entropy production reaches a minimum at the steady state, ensuring the asymptotic stability of the closed-loop system. The method is applied to design the power-level control law of high-temperature gas-cooled reactors, providing a new perspective on managing thermodynamic system dynamics. Furthermore, the research reveals the impact of control gain on control performance, offering insights for control strategy optimization.",

This is done first establishing equivalences among key variables in both domains through the comparison of the expressions of the stored system energy in both formalisms. Later, with the help of the general field-representation of bond graphs and its associated standard implicit form, the functions characterizing this class of Port-Hamiltonian Systems, i.e., interconnection, dissipation and input/output matrices, as well as their properties, are immediately expressed in terms of bond graphs parameters. Under suitable assumptions, the method supports the direct derivation of Input-State-Output Port-Hamiltonian Systems – which is an explicit type of PHS – even from bond graphs having causally coupled dissipators and storages in derivative causality, which are known to imply algebraic and implicit differential equations. The methods are illustrated with some application examples covering different causal situations. Besides its intrinsic interest as a technique for model conversion, the contribution is seen as a useful step towards implementing Port-Hamiltonian based control system design methods with the support of BG techniques.",

      "abstract": "This paper presents a methodology to perform energy shaping and interconnection and damping assignment in the bond graph domain, and addresses a new result on integral action control which improves the robustness of these passivity based control methods, which were first introduced on the port-controlled Hamiltonian systems with dissipation formalism. The methods perform expressing the desired closed-loop energy, interconnection and damping properties on a so-called target bond graph, which is built as follows on the plant bond graph: (i) adding virtual storage elements enforces a minimum on the target bond graph energy at a prespecified stable closed-loop equilibrium state, (ii) changing the R -field and its interconnection with the rest of the graph assigns a new dissipation function, and (iii) suitably inserting of power conserving elements (bonds and other structural BG-elements) among junctions yields the desired power conserving interconnection structure. The control law is then determined developing physically based heuristics and formal techniques on the target and plant bond graphs, which deliver a set of partial differential equations to be solved. The method to achieve integral control consists in adding to the target bond graph virtual elements representing the integral action and a change of variables, and then computing the integral control law with standard BG equation-reading procedures. These BG heuristics and prototyping allow to provide integral action on outputs of relative degree greater than one, a contribution of this work not previously available in the literature. This shows that the physical properties of bond graphs are beneficial not only to expediently perform methods contributed by control theory, but also to derive new theoretical results.",

      "abstract": "This paper presents a new way to derive an optimal control system for a specific optimisation problem, based on bond graph formalism. The procedure proposed concerns the optimal control of linear time invariant MIMO systems and can deal with both cases of the integral performance index, these correspond to dissipative energy minimization and output error minimization. An augmented bond graph model is obtained starting from the bond graph model of the system associated with the optimal control problem. This augmented bond graph, consisting of the original model representation coupled to an optimizing bond graph, supplies, by its bicausal exploitation, the set of differential-algebraic equations that analytically give the solution to the optimal control problem without the need to develop the analytical steps of Pontryagin’s method. The proof uses the Pontryagin Maximum Principle applied to the port-Hamiltonian formulation of the system.",

Based on the dissipation structure matrix of this port-Hamiltonian LuGre model, an alternative proof can be given for the passivity conditions that are known in the literature. As a specific example, the interconnection of a mass with the port-Hamiltonian LuGre model is presented. It is shown that the lossless-interconnection structure and dissipation structure of the port-Hamiltonian LuGre model are consistent with those of this interconnection. As an additional example, the port-Hamiltonian formulation of a quarter-car system with a LuGre-based tyre model is presented.",

More precisely, we give conditions under which a general nonlinear system can be transformed into a PCH system via static state feedback. We consider the two extreme cases where the target PCH system is completely a priori fixed or completely free, as well as the case where it is only partially predetermined. When the energy function is free a set of partial differential equations needs to be solved, on the other hand, if it is fixed we have to deal with a set of algebraic equations. In the former case, we give some verifiable necessary and sufficient conditions for solvability. As a by-product of our analysis we obtain some stabilization results for nonlinear systems.",

We propose an algorithm for constructing an approximate discrete-time model, which guarantees Hamiltonian conservation. We show that the algorithm also preserves, in a weaker sense, the losslessness property of a class of port-controlled Hamiltonian systems. An application of the algorithm to port-controlled Hamiltonian systems with quadratic Hamiltonian is presented, and we use this to solve the stabilization problem for this class of systems based on the approximate discrete-time model constructed using the proposed algorithm. We illustrate the usefulness of the algorithm in designing a discrete-time controller to stabilize the angular velocity of the dynamics of a rigid body.",

Discrete models can be obtained either by discretizing a smooth model, or by directly modeling at the discrete level itself. One of the goals of this paper is to model port-Hamiltonian systems at the discrete level. We also show that the dynamics of the discrete models we obtain exactly correspond to the dynamics obtained via a usual discretization procedure. In this sense we offer an alternative to the usual procedure of modeling (at the smooth level) and discretization.",

      "abstract": "Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) is a technique that regulates the behavior of nonlinear systems assigning a desired (Port Hamiltonian) structure to the closed-loop. This basic idea, introduced seven years ago, has turned out to be very successful and has provided solutions to a wide variety of physical problems. Although IDA-PBC is originally formulated as a static state-feedback technique a natural question that arises is whether it is possible to extend the realm of applicability of the method by considering dynamic controllers. More precisely, is the set of plants that is stabilizable with static state-feedback IDA-PBC smaller than the one stabilizable with dynamic IDA-PBC? The main contribution of this paper is to prove that the answer to this question is, unfortunately, negative.",

      "abstract": "Passivity-based controllers (PBCs) achieve stabilization of nonlinear systems, rendering the closed-loop passive with a desired energy (storage) function. A natural question is, under which conditions is it possible to make this function equal to the difference between the plant and controller energies—when the controller is said to be energy-balancing. In this paper we prove that a necessary and sufficient condition for energy-balancing is that the open and the closed-loop systems have the same dissipation functions and passive outputs. A second contribution of our work is the identification of a new passive output for Port–Hamiltonian systems, which is invariant to the action of PBCs that modify only the energy function–so-called basic interconnection and damping assignment PBCs–proving that they are energy-balancing. To establish these results a new algebraic framework for analysis and design of PBCs, centered around the principles of output and dissipation invariance, is developed. Using this framework several PBC schemes reported in the literature are compared. Also, we present a systematic procedure to generate new passive outputs, this result is of interest on its own, since it allows to extend the applicability of PBC to systems that are non-minimum phase and/or have relative degree larger than one.",

The proposed approach is justified by the fact that the adopted spatial discretization technique is able to preserve Casimir functions in the closed-loop system when going from the distributed to the (approximated) lumped parameter system. Besides the intrinsic difficulties related to the large number of state variables, the finite element model is generally given in terms of a Dirac structure and is completely a -causal, which implies that the plant dynamics is not given in standard input-state-output form, but as a set of DAEs. Consequently, the classical energy Casimir method has to be extended in order to deal with dynamical systems with constraints, usually appearing in the form of Lagrangian multipliers. The general methodology is illustrated with the help of an example in which the distributed parameter system is a lossless transmission line.",

      "abstract": "Regulation of passive outputs of nonlinear systems can be easily achieved with an integral control (IC). In many applications, however, the signal of interest is not a passive output and ensuring its regulation remains an open problem. Also, IC of passive systems rejects constant input disturbances, but no similar property can be ensured if the disturbance is not matched. In this paper we address the aforementioned problems and propose a procedure to design robust ICs for port-Hamiltonian models, that characterize the behavior of a large class of physical systems. Necessary and sufficient conditions for the solvability of the problem, in terms of some rank and controllability properties of the linearized system, are provided. For a class of fully actuated mechanical systems, a globally asymptotically stabilizing solution is given. Simulations of the classical pendulum system illustrate the good performance of the scheme.",

The main idea is to construct a reduced-order Dirac structure corresponding to zero power flow in some of the energy-storage ports. This can be performed in two canonical ways, called the effort- and the flow-constraint methods. We show how the effort-constraint method can be regarded as a projection-based model reduction method. Both the effort- and flow-constraint reduction methods preserve the stability and passivity properties of the original system, as a consequence of preserving the port-Hamiltonian structure.",

Implicit representations arise when a system is modeled in Cartesian coordinates and when the system constraints are applied in the form of additional algebraic equations. Explicit representations are derived when generalized coordinates are used. A relationship between the phase spaces for both system representations is derived in this article, justifying the equivalence of the representations in the sense of preserving their Hamiltonian functions as well as their Hamiltonian symplectic forms, ultimately resulting in the same Hamiltonian flow.",

      "abstract": "Control contact systems represent controlled (or open) irreversible processes which allow us to represent simultaneously the energy conservation and the irreversible creation of entropy. Such systems systematically arise in models established in Chemical Engineering. The differential-geometric of these systems is a contact form in the same manner as the symplectic 2-form is associated to Hamiltonian models of mechanics. In this paper we study the feedback preserving the geometric structure of controlled contact systems and render the closed-loop system again as a contact system. It is shown that only a constant control preserves the canonical contact form, hence a state feedback necessarily changes the closed-loop contact form. For strict contact systems, arising from the modelling of thermodynamic systems, a class of state feedback that shapes the closed-loop contact form and contact Hamiltonian function is proposed. The state feedback is given by the composition of an arbitrary function and the control contact Hamiltonian function. The similarity with structure preserving feedback of input–output Hamiltonian systems leads to the definition of input–output contact systems and to the characterization of the feedback equivalence of input–output contact systems. An irreversible thermodynamic process, namely the heat exchanger, is used to illustrate the results.",

      "abstract": "We consider a basic model of a dynamical distribution network, modeled as a directed graph with storage variables corresponding to every vertex and flow inputs corresponding to every edge, subject to unknown but constant inflows and outflows. As a preparatory result it is shown how a distributed proportional–integral controller structure, associating with every edge of the graph a controller state, will regulate the state variables of the vertices, irrespective of the unknown constant inflows and outflows, in the sense that the storage variables converge to the same value (load balancing or consensus). This will be proved by identifying the closed-loop system as a port-Hamiltonian system, and modifying the Hamiltonian function into a Lyapunov function, dependent on the value of the vector of constant inflows and outflows. In the main part of the paper the same problem will be addressed for the case that the input flow variables are constrained to take value in an arbitrary interval. We will derive sufficient and necessary conditions for load balancing, which only depend on the structure of the network in relation with the flow constraints.",

      "abstract": "Aim of this paper is to show how the Dirac structure properties can be exploited in the development of energy-based boundary control laws for distributed port-Hamiltonian systems. Usually, stabilization of non-zero equilibria has been achieved by looking at, or generating, a set of structural invariants, namely Casimir functions, in closed-loop. Since this approach fails when an infinite amount of energy is required at the equilibrium (dissipation obstacle), this paper illustrates a novel approach that enlarges the class of stabilizing controllers. The starting point is the parametrization of the dynamics provided by the image representation of the Dirac structure, that is able to show the effects of the boundary inputs on the state evolution. In this way, energy-balancing and control by state-modulated source methodologies are extended to the distributed parameter scenario, and a geometric interpretation of these control techniques is provided. The theoretical results are discussed with the help of a simple but illustrative example, i.e. a transmission line with an RLC load in both serial and parallel configurations. In the latter case, energy-balancing controllers are not able to stabilize non-zero equilibria because of the dissipation obstacle. The problem is solved thanks to a (boundary) state-modulated source.",

      "abstract": "Conservation laws and balance equations for physical network systems typically can be described with the aid of the incidence matrix of a directed graph, and an associated symmetric Laplacian matrix. Some basic examples are discussed, and the extension to k -complexes is indicated. Physical distribution networks often involve a non-symmetric Laplacian matrix. It is shown how, in case the connected components of the graph are strongly connected, such systems can be converted into a form with balanced Laplacian matrix by constructive use of Kirchhoff’s Matrix Tree theorem, giving rise to a port-Hamiltonian description. Application to the dual case of asymmetric consensus algorithms is given. Finally it is shown how the minimal storage function for physical network systems with controlled flows can be explicitly computed.",

Energy shaping is used for the purpose of stabilizing a desired equilibrium. When using implicit models, the problem turns out to be a simple quadratic programming problem (as opposed to the partial differential equations that need to be solved when using explicit representations). The described approach is generalized to address the problem of stabilization of homoclinic orbits thus leading to the formulation of swing-up strategies for underactuated systems.",

These equations occur in various applications, e. g., in combustion engines or chemical reactors. After modeling, discretization, and model reduction, important system properties as the energy conservation are usually lost which may lead to unphysical simulation results. In this paper, we introduce a port-Hamiltonian formulation of the one-dimensional Navier–Stokes equations for reactive flows. The port-Hamiltonian structure is directly associated with an energy balance, which ensures that a temporal change of the total energy is only due to energy flows through the boundary. Furthermore, the boundary ports may be used for control purposes.",

      "abstract": "In this paper a passive integrator dedicated to input/output Hamiltonian systems approximation is presented. In a first step, a discrete Hamiltonian framework endowed with a Lie derivative-like formula is introduced. It is shown that the discrete dynamics encodes energy conservation and passivity. Additionally, the characterization of the discrete dynamics in terms of Dirac structure is shown to be invariant by interconnection. The class is thus composable: networked systems belong to the class. In a second step, the discrete dynamics is considered as a one-step integration method. The method is shown to be convergent and provides a discrete-time approximation of an input/output Hamiltonian system. Accordingly, the discrete dynamics inherits intrinsic energetic characteristics (storage function and dissipation rate) from the original system. The method is thus tagged as passive integrator. As an illustration, the closed-loop behavior of interconnected subsystems and the stabilization of a rigid body spinning around its center of mass are presented.",

      "abstract": "In this paper, we examine the shifted passivity property of port-Hamiltonian systems. Shifted passivity accounts for the fact that in many applications the desired steady-state values of the input and output variables are nonzero, and thus one is interested in passivity with respect to the shifted signals. We consider port-Hamiltonian systems with strictly convex Hamiltonian, and derive conditions under which shifted passivity is guaranteed. In case the Hamiltonian is quadratic and state dependency appears in an affine manner in the dissipation and interconnection matrices, our conditions reduce to negative semidefiniteness of an appropriately constructed constant matrix. Moreover, we elaborate on how these conditions can be extended to the case when the shifted passivity property can be enforced via output feedback, thus paving the path for controller design. Stability of forced equilibria of the system is analyzed invoking the proposed passivity conditions. The utility and relevance of the results are illustrated with their application to a 6th order synchronous generator model as well as a controlled rigid body system.",

      "abstract": "A geometric spatial reduction method is presented in this paper. It applies to port Hamiltonian models for open systems of balance equations. It is based on projections which make use of the spatial symmetries in the model and preserve the “natural” power pairing. Reductions from 3D to 2D and 1D domains are illustrated via two examples. The first one is a vibro-acoustic system with cylindrical symmetry where 3D–2D reduction is applied. The second one is the system of two coupled parabolic equations describing the poloidal magnetic flux diffusion and heat radial transport in tokamak reactors. In this latter example the toroidal symmetry allows to perform a 3D–1D reduction. Obtained reduced models are compared with the common control models found in the literature for these two examples.",

The main idea is to use system theory to write the nonlinear PDE as a well-posed infinite-dimensional linear system interconnected with a static nonlinearity. By a simple example, it is shown that in general well-posedness of the closed-loop system is not guaranteed. We show that well-posedness of the closed-loop system is guaranteed for linear systems whose input to output map is coercive for small times interconnected to monotone nonlinearities. This work generalizes the results presented in [1], where only globally Lipschitz continuous nonlinearities were considered. Furthermore, it is shown that a general class of linear port-Hamiltonian systems satisfies the conditions asked on the open-loop system. The result is applied to show well-posedness of a system consisting of a vibrating string with nonlinear damping at the boundary.",

We discretize the underlying continuous-time Dirac structure with the collocation method and add discrete-time dynamics by the use of symplectic numerical integration schemes. The conservation of a structural discrete-time energy balance – expressed in terms of the discrete-time Dirac structure – extends the notion of symplecticity of geometric integration schemes to open systems. We discuss the energy approximation errors in the context of the presented definition and show that their order for linear PH systems is consistent with the order of the numerical integration scheme. Implicit Gauss–Legendre methods and Lobatto IIIA/IIIB pairs for partitioned systems are examples for integration schemes that are covered by our definition. The statements on the numerical energy errors are illustrated by elementary numerical experiments.",

Our motivation in this study is two-fold, on one hand, it is well-known that many physical systems are described by port-Hamiltonian models. On the other hand, contraction is a fundamental property that has been efficiently exploited for the design of observers, as well as tracking, adaptive and multi-agent controllers for nonlinear systems. The conditions for contraction are given in terms of feasibility of linear matrix inequalities, hence their verification is computationally efficient.",

Employing  results on evolution families, we show C 1 -well-posedness of the corresponding Cauchy problem, and thereby existence and uniqueness of classical solutions for sufficiently regular initial data. Further, we demonstrate that a dissipation condition in the style of the dissipation condition sufficient for uniform exponential stability in the autonomous case also leads to a uniform exponential decay rate of the energy in this non-autonomous setting.",

We exploit a port-Hamiltonian system description based on an underlying jet-bundle formalism, where we restrict ourselves to systems with 2nd-order Hamiltonian. A certain power-conserving interconnection enables the application of a dynamic control law based on structural invariants. Furthermore, we use various examples such as beams and plates with in-domain actuation to demonstrate the capability of our approach.",

This paper proposes Stokes–Dirac structures with respect to which port-Hamiltonian representations for such two-phase flow models can be obtained. We introduce a non-quadratic candidate Hamiltonian function and present dissipative Hamiltonian representations for both models. We then use the structure of the corresponding formally skew-adjoint operator to derive a Stokes–Dirac structure for the two variants of multi-phase flow models. Moreover, we discuss the difficulties in deriving a port-Hamiltonian formulation of the DFM with general slip conditions, and argue why this model may not be energy-consistent.",

      "abstract": "This paper, puts in discussion the structural identifiability of LTI Port-Controlled Hamiltonian (PCH) systems, in order to develop a specific identification and control theory. This is due to their remarkable properties of power conservation and stability under power preserving interconnection. The main part of the paper, presents a power based identifiability approach, with specific propositions and definitions. It is based on the power knowledge associated with the system ports, interconnected by a Dirac structure, for selected input signals. In a preliminary section, corresponding transfer functions, system outputs, Markov parameters, observability conditions, port-observability or infinite Grammians are defined for each port. Beside this, a port-identifiability concept is introduced for the identifiability analysis of one port. It is proved that between the input and system ports, a specific model can be determined for identification analysis, preserving in the same time the PCH structure. As examples to demonstrate the theory, a controlled LC circuit and a DC motor are selected for the lossless and lossy cases, respectively.",

      "abstract": "In this note, an enhanced trajectory tracking (or equivalently, tracking-error) approach is developed for the control of nonlinear systems whenever the stage of feedback passivation design prior to synthesizing state feedback controllers is impossible. To achieve this purpose while using the original state vector to retain its interpretation, it is possible without the use of input and state coordinate transformations to combine the system dynamics with the so-called extended quadratic port-Hamiltonian (PH) models (including possibly the quadratic pseudo PH models) which are then divided into non-relaxing and relaxing ones for further study on control benefits. Interestingly, both cases are associated to a unifying quadratic Hamiltonian storage function similar to that of electrical, mechanical, or electromechanical systems with a specific insight. Sufficient conditions for the global asymptotic or exponential convergence of the system trajectory to the reference one are shown. In addition, a Proportional–Integral action can be added to the tracking control for improving the closed-loop performance and robustness. The proposed approach is illustrated via two case studies, including the non-minimum phase Van de Vusse reaction system and the 3-DOF SCARA robot.",

      "abstract": "This paper proposes a Control by Interconnection design, for a class of constrained Port-Hamiltonian systems, which is based on an associated Model Predictive Control optimization problem. This associated optimization problem allows to consider both state and input constraints simultaneously. Based on the first order Karush–Kuhn–Tucker optimality condition, the primal–dual gradient method is then used to build a passive feedback controller, derived from the MPC-induced optimization problem. The resulting passive controller is coupled with the original Port-Hamiltonian system through a power-preserving interconnection, in order to guarantee both the closed-loop stability and constraints satisfaction, but not the optimality anymore. Comments on parameters tuning for the proposed control design, together with validations of the approach through simulations first on a linear LC circuit, then on a nonlinear Permanent Magnet Synchronous Motor and comparisons with a classical MPC design, are provided to discuss the effectiveness of the approach.",

We show that a commonly used empirical model of a pump leads to a port-Hamiltonian (pH) and hence stable system. We use standard arguments to show that WDNs are incrementally pH, and show that local PI controllers preserve stability. These controllers are robust in that they do not require specific knowledge of the equilibrium input. We further show that controllers based on physical feedback that WDN operators usually rely on have merit in the pH framework. All of these controllers are shown to be useful in mitigating disturbances and tracking setpoints corresponding to assignable equilibria.",

By a modification of the two central algebraic Riccati equations, we ensure that the resulting controller will be port-Hamiltonian. Using these modified equations, we proceed to show that a corresponding balanced truncation approach preserves port-Hamiltonian structure. We illustrate the theoretical findings using numerical examples and observe that the chosen representation of the port-Hamiltonian system can have an influence on the approximation qualities of the reduced order model.",

      "abstract": "In this paper, we introduce the notions of generalized controllability and observability functions for stable continuous-time nonlinear systems. We propose a balanced realization for nonlinear port-Hamiltonian systems in which the generalized energy functions are balanced and at the same time the Hamiltonian of the corresponding system is in diagonal form. The reduced order model obtained by truncation of states in the balanced coordinates preserves the port-Hamiltonian structure. For a special case of nonlinear port-Hamiltonian systems with quadratic Hamiltonian, the approach of generalized balanced truncation boils down to a feasibility problem of matrix inequalities. We illustrate the results with an example of a mass–spring–damper system with Coulomb friction.",

The incorporation of algebraic constraints has led to a multitude of definitions of port-Hamiltonian differential–algebraic equations (DAE) systems in the literature. This paper presents extensions of results obtained in Gernandt et al. (2021); Mehrmann and van der Schaft (2023) in the context of maximally monotone structures, and shows that any such structure can be written as the composition of a Dirac and a resistive structure. This yields an alternative, but equivalent, definition of linear port-Hamiltonian DAE systems with certain advantages. In particular, it leads to simpler coordinate representations, as well as to explicit expressions for the associated transfer functions.",

      "abstract": "We present a new optimization-based structure-preserving model order reduction (MOR) method for port-Hamiltonian differential–algebraic equations (pH-DAEs). Our method is based on a novel parameterization that allows us to represent any linear time-invariant pH-DAE of a prescribed model order. We propose two algorithms which directly optimize the parameters of a reduced model to approximate a given large-scale model with respect to either the H ∞ or the H 2 norm. This approach has several benefits. Our parameterization ensures that the reduced model is again a pH-DAE system and enables a compact representation of the algebraic part of the large-scale model, which in projection-based methods often requires a more involved treatment. The direct optimization is entirely based on transfer function evaluations of the large-scale model and is therefore independent of the structure of the system matrices. Numerical experiments are conducted to illustrate the high accuracy and small reduced model orders in comparison to other structure-preserving MOR methods.",

      "abstract": "In this paper, we develop a systematic approach to stabilize a general class of hyperbolic systems while assigning them a specified closed-loop behavior with a clear energy interpretation. More precisely, we address in-domain dissipation assignment for boundary-controlled Port Hamiltonian systems. The controller is designed so that the closed-loop system behaves like a target system with a specified energy decay rate. The PHS framework is used to take advantage of the natural physical properties of the system to define well-posed, exponentially stable, and easily parametrizable target system candidates, thus resulting in modular controllers. Under some generic structural assumptions, we rewrite the considered Port Hamiltonian system in the Riemann coordinates. The control approach is then based on the backstepping methodology. We combine classical Volterra transformations with an innovative time-affine transform to map the original system to the desired target system. The proposed approach is applied to two test cases: a clamped string and a clamped Timoshenko beam. Both are illustrated in numerical simulations.",

      "abstract": "This paper shows a finite-dimensional controller design for the boundary control of the heat equation on a 1D spatial domain. The controller exponentially stabilizes the plant at the desired equilibrium profile. The controller is defined using irreversible port-Hamiltonian systems formulation, and it is motivated by passivity-based control techniques developed for port-Hamiltonian systems defined on 1D spatial domains. The boundary controller is designed to have an exponentially stabilizing energy-shaping and entropy-assignment effect. It works with an actuation at one boundary and a reflective boundary condition at the other. The controller can handle situations where measurements are available at only one or both boundaries. The paper characterizes the existence of structural invariant functions to shape the closed-loop energy and assign the required closed-loop entropy. The design approach is illustrated through numerical simulations.",

In particular, we are concerned with optimal state transitions and output stabilization on finite-time horizons. We analyze a class of optimal control problems, where the performance functional can be interpreted as a linear combination of energy supply, entropy generation, or exergy supply. Our results establish the integral turnpike property towards the set of thermodynamic equilibria providing a rigorous connection of optimal system trajectories to optimal steady states. Throughout the paper, we illustrate our findings by means of two examples: a network of heat exchangers and a gas-piston system.",

      "abstract": "This paper presents a systematic methodology for the discretization and reduction of a class of one-dimensional Partial Differential Equations (PDEs) with inputs and outputs collocated at the spatial boundaries. The class of system that we consider is known as Boundary-Controlled Port-Hamiltonian Systems (BC-PHSs) and covers a wide class of Hyperbolic PDEs with a large type of boundary inputs and outputs. This is, for instance, the case of waves and beams with Neumann, Dirichlet, or mixed boundary conditions. Based on a Partitioned Finite Element Method (PFEM), we develop a numerical scheme for the structure-preserving spatial discretization for the class of one-dimensional BC-PHSs. We show that if the initial PDE is passive (or Impedance Energy Preserving), the discretized model also is. In addition and since the discretized model or Full Order Model (FOM) can be of large dimension, we recall the standard Loewner framework for the Model Order Reduction (MOR) using frequency domain interpolation. We recall the main steps to produce a Reduced Order Model (ROM) that approaches the FOM in a given range of frequencies. We summarize the steps to follow in order to obtain a ROM that preserves the passive structure as well. Finally, we provide a constructive way to build a projector that allows to recover the physical meaning of the state variables from the ROM to the FOM. We use the one-dimensional wave equation and the Timoshenko beam as examples to show the versatility of the proposed approach.",

      "abstract": "In this note, we consider port-Hamiltonian structures in numerical optimal control of ordinary differential equations. By introducing a novel class of nonlinear monotone port-Hamiltonian (pH) systems, we show that the primal–dual gradient method may be viewed as an infinite-dimensional nonlinear pH system. The monotonicity and the particular block structure arising in the optimality system is used to prove exponential stability of the dynamics towards its equilibrium, which is a critical point of the first-order optimality conditions. Leveraging the port-based modeling, we propose an optimization-based controller in a suboptimal receding horizon control fashion. To this end, the primal–dual gradient based optimizer-dynamics is coupled to a pH plant dynamics in a power-preserving manner. We show that the resulting model is again monotone pH system and prove that the closed-loop exhibits local exponential convergence towards the equilibrium.",

We show that under mild assumptions, the finite cost condition is always satisfied. Moreover, we give an explicit bound on the norm of the optimal cost operator. In the case where the system is energy preserving, the unique optimal control is given together with the corresponding optimal cost operator. In this case, we derive an explicit solution to an adapted operator Riccati equation. We apply our results to boundary control systems, first-order port-Hamiltonian systems and an Euler–Bernoulli beam with shear force control.",

      "abstract": "In this paper, Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) notion is utilized to design a novel controller for teleoperation systems with asymmetric variable time delay in the communication channel and passive/non-passive interaction forces. By shaping both of the kinetic and potential energies, the performance of position and force tracking is improved compared to conventional controllers. Using the Lyapunov–Krasovskii theorem, sufficient synthesis conditions are derived in terms of Linear Matrix Inequalities (LMIs) to ensure stable position and force tracking in the system. The dynamical models of actuators, i.e. Direct Current (DC) motors, are considered in the design of control law. Finally, comparative simulation results are presented to demonstrate the superiority of the proposed method contrasted to some recent rival methods in the literature. The real-world applicability of the proposed control strategy is verified by the laboratory experiments.",

      "abstract": "Passivity-based control (PBC) is a well-established technique that has shown to be very powerful to design robust controllers for physical systems described by Euler–Lagrange (EL) equations of motion. For regulation problems of mechanical systems, which can be stabilized “shaping” only the potential energy, PBC preserves the EL structure and furthermore assigns a closed-loop energy function equal to the difference between the energy of the system and the energy supplied by the controller. Thus, we say that stabilization is achieved via energy balancing. Unfortunately, these nice properties of EL–PBC are lost when used in other applications which require shaping of the total energy, for instance, in electrical or electromechanical systems, or even some underactuated mechanical devices. Our main objective in this paper is to develop a new PBC theory which extends to a broader class of systems the aforementioned energy-balancing stabilization mechanism and the structure invariance. Towards this end, we depart from the EL description of the systems and consider instead port-controlled Hamiltonian models, which result from the network modelling of energy-conserving lumped-parameter physical systems with independent storage elements, and strictly contain the class of EL models.",

In particular, the relationships between nonlinear Hilbert adjoint operators, Hamiltonian extensions and port-controlled Hamiltonian systems are established. Then, characterizations of the adjoints of controllability, observability and Hankel operators are derived from this analysis. The state-space realizations of such adjoint operators provide new insights on singular value analysis and duality issues in nonlinear control systems theory. Finally, a duality between the controllability and observability energy functions is proved.",

      "abstract": "In the last decades, several researchers have concentrated on the dynamic modeling of nonlinear electrical circuits from an energy-based perspective. A recent perspective is based on the concept of port-Hamiltonian (PH) systems. In this paper, we discuss the relations between the classical Brayton–Moser (BM) equations—stemming from the early sixties—and PH models for topologically complete nonlinear RLC circuits, with and without controllable switches. It will be shown that PH systems precisely dualize the BM equations, leading to possible advantages at the level of controller design. Consequently, useful and important properties of the one framework can be translated to the other. Control designs for the PH model cannot be directly implemented since they require observation of flux and charges, which are not directly available through standard sensors, while the BM models require only observation of currents and voltages. The introduced duality allows to pull back PH designs to the space of currents and voltages. This offers the possibility to exchange several different techniques, available in the literature, for modeling, analysis and controller design for RLC circuits. Illustrative examples are provided to emphasize the duality between both frameworks.",

Furthermore, an inverse optimal hybrid feedback control framework is developed that characterizes a class of globally stabilizing energy-based controllers that guarantee hybrid sector and gain margins to multiplicative input uncertainty of hybrid Hamiltonian systems.",

We follow the approach proposed by van der Schaft and Maschke and extract from the basic (energy-conserving) LC–circuit the remaining elements, i.e., resistors, switches, diodes and transformers, which we treat as external ports. This method naturally yields a Hamiltonian system with two additional conjugated sets of port variables. This procedure, besides being systematic and very general, has the additional advantage of resulting in equations of a form appropriate for simulation and design of the highly succesful passivity–based controllers.",

      "abstract": "The aim of this paper is to provide an intrinsic Hamiltonian formulation of the equations of motion of network models of non-resistive physical systems. A recently developed extension of the classical Hamiltonian equations of motion considers systems with state space given by Poisson manifolds endowed with degenerate Poisson structures, examples of which naturally appear in the reduction of systems with symmetry. The link with network representations of non-resistive physical systems is established using the generalized bond graph formalism which has the essential feature of symmetrizing all the energetic network elements into a single class and introducing a coupling unit gyrator. The relation between the Hamiltonian formalism and network dynamics is then investigated through the representation of the invariants of the system, either captured in the degeneracy of the Poisson structure or in the topological constraints at the ports of the gyrative type network structure. This provides a Hamiltonian formulation of dimension equal to the order of the physical system, in particular, for odd dimensional systems. A striking example is the direct Hamiltonian formulation of electrical LC networks.",

      "abstract": "It is shown that the intrinsic geometry associated with equilibrium thermodynamics, namely the contact geometry, provides also a suitable framework in order to deal with irreversible thermodynamical processes. Therefore we introduce a class of dynamical systems on contact manifolds, called conservative contact systems, defined as contact vector fields generated by some contact Hamiltonian function satisfying a compatibility condition with some Legendre submanifold of the contact manifold. Considering physical systems' modeling, the Legendre submanifold corresponds to the definition of the thermodynamical properties of the system and the contact Hamiltonian function corresponds to the definition of some irreversible processes taking place in the system. Open thermodynamical systems may also be modeled by augmenting the conservative contact systems with some input and output variables (in the sense of automatic control) and so-called input vector fields and lead to the definition of port contact systems. Finally complex systems consisting of coupled simple thermodynamical or mechanical systems may be represented by the composition of such port contact systems through algebraic relations called interconnection structure. Two examples illustrate this composition of contact systems: a gas under a piston submitted to some external force and the conduction of heat between two media with external thermostat.",

A special class of time-varying generalized canonical transformations are introduced which modify the kinetic energy of the original system without changing the generalized Hamiltonian structure with passivity. Utilizing these transformations, time-varying asymptotically stabilizing controllers for the nonholonomic Hamiltonian systems are derived. Since the proposed method is a natural generalization of passivity based control for conventional holonomic systems, it is expected that the tools developed for conventional systems will be applicable to nonholonomic systems based on the proposed method.",

Two sets of (almost) equivalent LMIs are proposed. In the first set, the interconnection and damping matrices do not appear explicitly, which makes it more difficult to directly manipulate those matrices. By requiring the system to have no uncontrollable pole at s=0, the second set of LMIs, explicitly containing the interconnection and damping matrices, can be obtained. Taking into account the physical properties of the system, some prespecified structures can be imposed directly on those matrices.",

The system is Hamiltonian with respect to an infinite-dimensional Dirac structure associated with the exterior derivative and based on Stokes’ theorem. The theory is applied to the telegraph equations for an ideal transmission line, Maxwell’s equations on a bounded domain with non-zero Poynting vector at its boundary, and a vibrating string with traction forces at its ends. Furthermore, the framework is extended to cover Euler’s equations for an ideal fluid on a domain with permeable boundary. Finally, some properties of the Stokes–Dirac structure are investigated, including the analysis of conservation laws.",

The procedure is essentially an adaptation of the procedure for discretization of Stokes-Dirac structures presented in (Clemente-Gallardo et al., 2002), that does not preserve the port-Hamiltonian structure after discretization. With some modifications essentially inspired on the finite difference paradigm, the procedure now results in a system that preserves the collocated port-Hamiltonian structure along with some other desirable conditions for interconnection. The simulation results are compared with those presented previously in (Golo et al., 2002).",

      "abstract": "This paper first addresses the question when a given (possibly nonlinear) RGLC circuit can be rewritten as a port-Hamiltonian (PH) system—with state variables the inductor currents and capacitor voltages instead of the fluxes and charges, respectively. The question has an affirmative answer for a class of circuits that fulfills a certain regularity condition. This class includes circuits where all dynamic elements are linear, and the associated resistors and conductors are passive—though possibly nonlinear. Interestingly, the resulting Hamiltonian function is related with the circuits instantaneous reactive power associated with the inductors and capacitors. This novel circuit representation, called a reactive port-Hamiltonian description, naturally suggests a new set of non-standard passive outputs, which are shown to be useful for the design of reactive power compensation schemes. A Van der Pol oscillator circuit is used to illustrate the developments throughout the paper.",

Thereby, it is the task of the impedance control system to produce a response to an external force which corresponds to the response of a predefined mechanical system, with a desired (nonlinear) stiffness and a desired (nonlinear) damping characteristics around a desired operating point of the piston position. The controller design is based on a port-Hamiltonian representation of the mathematical model utilizing the fundamental thermodynamic relations of an isentropic fluid.",

The issues of constructing a discrete-time model for Hamiltonian system are in general different from those for dissipative systems. We propose an algorithm for constructing an approximate discrete-time model, which guarantees the Hamiltonian conservation, and apply the algorithm to a class of port-controlled Hamiltonian systems. We illustrate the usefulness of the algorithm in designing a discrete-time controller to stabilize the angular velocity of a rigid body.",

A generalization of Passivity Based Control is proposed and fitted to bond graph formalism in the general case where derivative causality occur in the models. The state equations deduced from the original bond graph models are first made explicit via a special variable change, then interpreted according to Port Controlled Hamiltonian formalism. The whole approach is presented in a formal way, and illustrated on the example of a power converter.",

A general framework of tracking control utilizing the passivity property is proposed. Firstly, it is shown how to construct an error system, which describes the dynamics of the tracking error, by a passive port-controlled Hamiltonian system. Secondly, a practical procedure to construct tracking controllers of port-controlled Hamiltonian systems including nonholonomic systems is derived. Finally, a simple example of tracking control of a nonholonomic system demonstrates the effectiveness of the proposed method. This method is a natural extension of the conventional passivity based control and is expected to derive robustly stable control systems.",

In particular the relationship among nonlinear Hilbert adjoint operators, Hamiltonian extensions and port-controlled Hamiltonian systems are clarified. The characterization of controllability, observability and Hankel operators, and controllability and observability functions will be derived based on it. Furthermore a duality between the controllability and observability functions will be proven. The statespace realizations ofsuch operators provide new insights to nonlinear control systems theory.",

At first we refer to the generalized canonical transformation which preserves the structure of Hamiltonian systems and the passivity property that physical systems innately possess. Next we show a general stabilization strategy for port-controlled Hamiltonian systems based on it which is a natural generalization of well-known passivity based control. Finally we utilize this method to mechanical Hamiltonian systems with nonholonomic constraints by modifying the kinetic energy of the system. Furthermore some examples are given to show how this technique works for physical systems.",

      "abstract": "this paper presents a systematic method, to obtain the hybrid Hamiltonian formulation of a class of linear switched systems (LSS). The advantages of this formulation are that the state of the switching part is explicit and the equations are directly related to the interconnection constraints and dissipation. The resulting port controlled Hamiltonian representation with dissipation is of course hybrid, including continuous and discrete variables. The network graph of the system gives its Dirac structure which is reduced in successive steps to obtain the Hamiltonian formulation.",

Since the introduction of this controller design methodology four years ago many theoretical extensions and practical applications have been reported in the literature. The theoretical developments include some useful variations and shortcuts that may be introduced when the technique is applied to particular classes of systems and the incorporation of additional features to handle control scenarios other than just stabilization. The purposes of this paper are to collect and present in a unified way some of the new theoretical results and to discuss the current research and future directions",

      "abstract": "Stabilization of nonlinear feedback passive systems is achieved assigning a storage function with a minimum at the desired equilibrium. For physical systems a natural candidate storage function is the difference between the stored and the supplied energies—leading to the so-called Energy-Balancing control, whose underlying stabilization mechanism is particularly appealing. Unfortunately, energy-balancing stabilization is stymied by the existence of pervasive dissipation, that appears in many engineering applications. To overcome the dissipation obstacle the method of Interconnection and Damping Assignment, that endows the closed-loop system with a special—port-controlled Hamiltonian—structure, has been proposed. If, as in most practical examples, the open-loop system already has this structure, and the damping is not pervasive, both methods are equivalent. In this brief note we show that the methods are also equivalent, with an alternative definition of the supplied energy, when the damping is pervasive. Instrumental for our developments is the observation that, swapping the damping terms in the classical dissipation inequality, we can establish passivity of port-controlled Hamiltonian systems with respect to some new external variables—but with the same storage function",

As an applicative example of the presented methodology, a flexible beam, modeled according to the Timoshenko theory, with a mass under gravity field connected to a free end, is considered. After the distributed port Hamiltonian (dpH) model of the beam is introduced, the control problem is discussed. The concept of structural invariant (Casimir function) is generalized to the infinite dimensional case and the so-called control by interconnection control technique is extended to the infinite dimensional case. In this way, finite dimensional passive controllers can stabilize distributed parameter systems by shaping their total energy, i.e. by assigning a new minimum in the desired equilibrium configuration that can be reached if a dissipation effect is introduced",

Following the nonlinear output regulation theory, the regulator which solves the problem is given by a parallel connection of two subcontrollers: an internal model unit and a regulator to stabilize the extended system composed by the plant and the internal model unit. The main idea is to use the PCHS theory in order to design that stabilizer controller: as in many cases the plant to be addressed is indeed a mechanical/electric system, and it is very easy to think about it as a PCHS, the paper shows the conditions to fulfill in order to design the internal model unit as a PCHS, allowing to use the powerful energy-shaping theory in order to stabilize the extended system. Moreover the same techniques are used to design an internal model based controller able to globally solve a problem of input disturbance suppression",

      "abstract": "This paper discusses the relation between the power continuous interconnection structure in network models and the geometric structure of Hamiltonian systems. Firstly the gyrative interconnection structure, characterizing interdomain coupling in physical systems, is related to the Poisson structure of Hamiltooian systems. Secondly, the concept of port interaction is used to define the interaction of Hamiltonian systems with their environment. Thirdly, different integrability assumptions, concerning the definition of interaction by interaction potentials and the Jacobi identities, are discussed. Finally it is presented how the previous results may be generalized to power continuous interconnection st1Uctures encompassing as well the power exchanges internal to a physical model as well as the exchanges with its environment. In this case the power continuous interconnection is related with Dirac structure, a geometric structure generalizing the Poisson bracket to constrained and implicit Hamiltonian systems.",

A first basic feature of these systems is that their internal dynamics is Hamiltonian with respect to a Poisson structure determined by the topology of the network and to a Hamiltonian given by the stored energy. Secondly the network representation provides automatically (intrinsically to the notation) to every port-control variable (input) a port-conjugated variable as output. This definition of port-conjugated input and output variables, based on energy considerations, is shown to have important consequences for the observability and controllability properties, as well as the external characterization of port- controlled Hamiltonian systems.",

      "abstract": "This paper investigates the output consensus problem of port-controlled Hamiltonian (PCH) multi-agent systems with both Fixed and switching topologies. Firstly, a distributed group output consensus protocol is designed via the energy shaping method to reach globally stability and group output consensus. Secondly, a new distributed control protocol is proposed by using the structural properties of the PCH systems. The advantage of this protocol is that it can transform the directed graph to the undirected graph by constructing a kind of virtual neighbors. Thirdly, a control protocol is designed with the extended LaSalle0s invariance principle developed for switched systems under the jointly connected topology condition to make all the agents reach output consensus when the topology is switching. Finally, some illustrative examples with simulations are provided to demonstrate the effectiveness of the protocols designed in this paper.",

They cover a class of linear time-invariant state/signal system that is general enough to include most of the standard classes of linear time-invariant dynamical systems, but simple enough that it is easy to understand the fundamental principles. They begin by explaining the basic theory of finite-dimensional and bounded systems in a way suitable for graduate courses in systems theory and control. They then proceed to the more advanced infinite-dimensional setting, opening up new ways for researchers to study distributed parameter systems, including linear port-Hamiltonian systems and boundary triplets. They include the general non-passive part of the theory in continuous and discrete time, and provide a short introduction to the passive situation. Numerous examples from circuit theory are used to illustrate the theory.",

This kind of system is useful for supervised hands-on training where a trainer interacts with a trainee through two haptic devices, in order to practice on a manual task performed on a virtual or teleoperated robot (e.g., for an Minimally Invasive Surgery (MIS) task in a surgical context). This paper details the proof of stability of an Energy Shared Control (ESC) architecture we previously introduced for one degree of freedom (d.o.f.) devices. An extension to multiple degrees of freedom is proposed, along with an enhanced version of the Adaptive Authority Adjustment function. Experiments are carried out with 3 d.o.f. haptic devices in free motion as well as in contact contexts in order to show the relevance of this architecture.",

      "abstract": "This paper proposes a robust controller for the generation of stable limit cycles in multi-input mechanical systems subjected to model uncertainties. The proposed idea is based on Port-Controlled Hamiltonian (PCH) model and energy-based control by considering the Hamiltonian function as the Lyapunov function. For this purpose, first, a nominal controller is designed by shaping the energy function of the system according to the structure of the desired limit cycle. Then, an additional robustifying control term is designed based on the integral sliding mode method with the selection of an appropriate sliding surface. Finally, computer simulations for two practical case studies are provided to confirm the effectiveness of the proposed controller in the generation of stable limit cycles in the presence of uncertainties.",

      "abstract": "<jats:p>The subject of geometric numerical integration deals with numerical integrators that preserve geometric properties of the flow of a differential equation, and it explains how structure preservation leads to improved long-time behaviour. This article illustrates concepts and results of geometric numerical integration on the important example of the Störmer–Verlet method. It thus presents a cross-section of the recent monograph by the authors, enriched by some additional material.</jats:p><jats:p>After an introduction to the Newton–Störmer–Verlet–leapfrog method and its various interpretations, there follows a discussion of geometric properties: reversibility, symplecticity, volume preservation, and conservation of first integrals. The extension to Hamiltonian systems on manifolds is also described. The theoretical foundation relies on a backward error analysis, which translates the geometric properties of the method into the structure of a modified differential equation, whose flow is nearly identical to the numerical method. Combined with results from perturbation theory, this explains the excellent long-time behaviour of the method: long-time energy conservation, linear error growth and preservation of invariant tori in near-integrable systems, a discrete virial theorem, and preservation of adiabatic invariants.</jats:p>",

      "abstract": "<jats:p>In the last few decades the concepts of structure-preserving discretization, geometric integration and compatible discretizations have emerged as subfields in the numerical approximation of ordinary and partial differential equations. The article discusses certain selected topics within these areas; discretization techniques both in space and time are considered. Lie group integrators are discussed with particular focus on the application to partial differential equations, followed by a discussion of how time integrators can be designed to preserve first integrals in the differential equation using discrete gradients and discrete variational derivatives.</jats:p><jats:p>Lie group integrators depend crucially on fast and structure-preserving algorithms for computing matrix exponentials. Preservation of domain symmetries is of particular interest in the application of Lie group integrators to PDEs. The equivariance of linear operators and Fourier transforms on non-commutative groups is used to construct fast structure-preserving algorithms for computing exponentials. The theory of Weyl groups is employed in the construction of high-order spectral element discretizations, based on multivariate Chebyshev polynomials on triangles, simplexes and simplicial complexes.</jats:p><jats:p>The theory of mixed finite elements is developed in terms of special inverse systems of complexes of differential forms, where the inclusion of cells corresponds to pullback of forms. The theory covers, for instance, composite piecewise polynomial finite elements of variable order over polyhedral grids. Under natural algebraic and metric conditions, interpolators and smoothers are constructed, which commute with the exterior derivative and whose product is uniformly stable in Lebesgue spaces. As a consequence we obtain not only eigenpair approximation for the Hodge–Laplacian in mixed form, but also variants of Sobolev injections and translation estimates adapted to variational discretizations.</jats:p>",

      "abstract": "We discuss the modelling framework of port-Hamiltonian descriptor systems and their use in numerical simulation and control. The structure is ideal for automated network-based modelling since it is invariant under power-conserving interconnection, congruence transformations and Galerkin projection. Moreover, stability and passivity properties are easily shown. Condensed forms under orthogonal transformations present easy analysis tools for existence, uniqueness, regularity and numerical methods to check these properties.After recalling the concepts for general linear and nonlinear descriptor systems, we demonstrate that many difficulties that arise in general descriptor systems can be easily overcome within the port-Hamiltonian framework. The properties of port-Hamiltonian descriptor systems are analysed, and time discretization and numerical linear algebra techniques are discussed. Structure-preserving regularization procedures for descriptor systems are presented to make them suitable for simulation and control. Model reduction techniques that preserve the structure and stabilization and optimal control techniques are discussed.The properties of port-Hamiltonian descriptor systems and their use in modelling simulation and control methods are illustrated with several examples from different physical domains. The survey concludes with open problems and research topics that deserve further attention.",

      "abstract": "It is a very important issue to minimise the change of the interconnect structure matrix when stabilising a port‐controlled Hamiltonian (PCH) system. Toward this problem, a parametric design method is proposed in this paper for a type of PCH systems. First, concepts of H‐damping‐assignable and H‐damping‐assigning controller are introduced, and the stability of the closed‐loop system resulting from this type of controller is discussed. Secondly, a necessary and sufficient condition for the system to be H‐damping‐assignable is given, and, when this condition is met, a parametric general expression of all the H‐damping‐assigning controllers is obtained. Thirdly, the free parameters are optimised to minimize the change of the interconnect structure matrix and also the norm of the control gain matrix. The parameter optimisation is formulated as a standard quadratic programming problem, to which analytical solutions are obtained. Finally, comparative simulations are carried out for a numerical example to verify the effect and the superiority of the proposed method.",

      "abstract": "The authors address the problem of tuning a non‐linear energy‐based regulator for the positioning of a surface marine craft. Interconnection and damping assignment passivity‐based control (IDA‐PBC) is used for the control design, resulting in passive target dynamics that can be expressed as a port‐Hamiltonian system (PHS). The IDA‐PBC methodology has been successfully utilised in several applications, however, there has been minimal development in tuning methods that can analytically assist the designer to achieve desired response characteristics. It is demonstrated that eigenvalue assignment of the linearised target dynamics in PHS form can significantly aid the tuning process. Based on this analysis, the authors propose a systematic tuning approach to achieve certain performance and response characteristics. A comprehensive demonstration of the proposed tuning method is provided for the position regulation of an underwater vehicle in the horizontal plane in a case study, where numerical analysis of robustness is also conducted.",

      "abstract": "The memristor is added to the port‐Hamiltonian systems to improve the disturbance suppression performance in this paper. The concepts of locally fixed‐time stability and locally fixed‐time control of port‐Hamiltonian systems are presented. From this starting point, two novel memristor‐based locally fixed‐time controllers are designed to suppress the external disturbance of port‐Hamiltonian systems via the interconnection and damping assignment passivity‐based control technique. Comparing with the classical interconnection and damping assignment passivity‐based control methodology without memristor, there are some advantages. First, the settling‐time related to the memristor‐based controllers in stabilizing the same port‐Hamiltonian systems are shorter. Second, the memristor‐based controllers can make the oscillation in the case of the strong periodic disturbance be better suppressed. Theoretical analysis shows that the memristor‐based controller possesses good disturbance rejection performance owing to it can make the system states in a neighbourhood accelerate convergence to the desired equilibrium point. Two illustrative examples show that the theoretical results and the controllers designed in this paper work very well.",

      "abstract": "This paper considers the problem of robust stabilization of linear time‐invariant systems with respect to unmodelled dynamics and structure uncertainties. To that end, a methodology to find the nearest negative imaginary system for a given non‐negative imaginary system is presented first. Then, this result is employed to construct a near optimal linear quadratic Gaussian controller achieving desired performance measures. The problem is formulated using port‐Hamiltonian method and the required conditions are defined in terms of linear matrix inequalities. The technique is presented using the fast gradient method to solve the problem systematically. The designed controller satisfies a negative imaginary property and guarantees a robust feedback loop. The effectiveness of the approach is demonstrated by a simulation on a numerical example.",

      "abstract": "In this article, a cooperative control combining deadbeat predictive control (DBPC) and state error port‐controlled Hamiltonian (EPCH) method is presented for permanent magnet synchronous motor drives. This effective combination is achieved by a cooperation scheme based on the error function. First, the DBPC is introduced to provide a fast dynamic response, and the state EPCH method based on the loss model is constructed to get good steady‐state performance and high efficiency. After that, to combine the advantages of both controllers, the improved sigmoid function based on real‐time position error is designed as a cooperative scheme. Each control method can be utilised effectively within the corresponding range. Meanwhile, the switching process is continuous and smooth without unnecessary chattering. Thus, the proposed method not only solves the contradiction between dynamic and steady performance but also optimises energy consumption. Finally, the proposed method is verified experimentally. The results show that the motor control system based on the proposed method has fast dynamic transient response and good steady‐state performance with high efficiency.",

      "abstract": "The poor damping of bidirectional dc (bi‐dc) converter caused by constant power load makes power system prone to oscillation, and non‐minimum phase characteristic also jeopardises voltage stability. To solve these challenges, the interconnection and damping assignment passivity‐based control (IDA‐PBC) is utilised to improve transient response. The influences of the right‐half‐plane (RHP) zero on the stability margin and controller design are illustrated by zero dynamics analysis. Then the port‐controlled Hamiltonian modelling is used to obtain the IDA‐PBC control law, which is suitable to the bi‐dc converter and independent of the operation mode. The system dissipation property is modified, and thus the desired damping is injected to smooth the transient voltage. To remove the voltage error caused by RHP zero and adjust the damping ratio, an energy controller with an adjustment factor is introduced. Besides, a virtual circuit is established to explain the physical meaning of the control parameter, and the parameter design method is given. Passivity analysis assesses the controller performance. Simulation results are analysed and compared with other control strategies to test the proposed IDA‐PBC strategy.",

      "abstract": "In converter‐based grids (CBGs) without support from the main grid or synchronous generators, grid‐forming converters (GFMs) are responsible for sustaining frequency and voltage stability. However, disturbances or load variations frequently lead to frequency and voltage deviations, and the operating point (OP) of GFM may not align with the desired stable state. Under severe faults, current‐limiting actions may be triggered, potentially leading to instability. This paper proposes a Port‐Hamiltonian (PH) framework‐based control strategy to optimise steady‐state operation and improve transient stability. A PH model of a GFM under VSG control is first derived, including its energy function and the stability region boundary imposed by current‐limiting constraints. Interconnection and damping assignment passivity‐based control (IDA‐PBC) is then employed to shape the system energy so the OP becomes the minimum of the energy function, while a PH‐structured integrator compensates for steady‐state frequency and voltage deviations. Leveraging PH structural properties enables unified modelling, stability analysis, and controller design, while simplifying the proof of closed‐loop stability. Finally, simulations on an IEEE 9‐bus CBG system validate the proposed method: the GFM tracks the desired equilibrium, avoids current‐limiting activation during faults, and returns to the pre‐fault OP with superior transient performance compared to the original uncontrolled case.",

      "abstract": "The majority of monitoring and control applications at a distribution system control center rely on the assumption that the distribution network is in quasi steady-state. Known limitations of the quasi steady-state assumption are its inability to capture fast transients and harmonic distortion. Both of them are induced by the large-scale integration of distributed energy sources (DES) and power electronics. This motivates a dynamic modeling of distribution grids since such an approach naturally obviates the steady-state assumption. In the literature, the dynamic modeling of distribution networks mainly leads to implicit models in forms of differential-algebraic equations (DAEs). In contrast, the explicit modeling in terms of ordinary differential equations (ODEs) has received limited attention. This is a problem as the model-based design of a controller and state estimator usually requires an explicit model. In this paper, we present a first approach towards a dynamic description of an unbalanced distribution grid by an explicit ODE model. A minimal system consisting of two buses and one three-phase three-wire line is considered. The contribution is twofold: first, we propose a time-domain dynamic model for the minimal system in form of an explicit Port-Hamiltonian system; secondly, the dynamic model is validated through experiments. The results show that the dynamic model can deal with both, fast transients and harmonic distortion.",

      "abstract": "Wind farms connected to series-compensated transmission lines have the risk of sub-synchronous oscillation (SSO). The most effective countermeasure against SSOs is to identify the primary cause and then eliminate it. However, it is challenging for existing measurement-based methods to locate SSO sources accurately and timely. To solve this problem, we propose a location method based on the Hamiltonian system theory for identifying the SSO source. Considering the electromagnetic transient process, an energy function for power systems with DFIGs is constructed using the Hamiltonian system theory. The SSO port energy is obtained based on the energy function, and then the SSO source location can be identified by determining the direction of the total SSO port energy flow of a sub-system. The effectiveness of the proposed method is verified through case studies. The results show that the disturbance source can be located accurately in the forced SSO scenario, and the participation of DFIGs can be evaluated based on the port energy in the negatively damped SSO scenario.",

First, the robustness of IDA‐PBC in the presence of non‐vanishing matched and unmatched uncertainties is analysed and sufficient conditions are derived to ensure ultimate boundedness of system. Second, the robust control design is provided by adding a new control input to the former controller designed by IDA‐PBC, such that asymptotic stability of the closed‐loop system in the face of non‐vanishing matched uncertainties is fulfilled. Finally, the proposed robust controller is evaluated through simulations of two practical examples, i.e. an inertia wheel pendulum and a single‐link elastic joint robot. The simulation outcomes clearly reveal the effectiveness of the presented robust controller.",

      "abstract": "This study presents a new non-linear passivity-based controller for a wound-rotor synchronous machine, acting as a motor drive. The control objectives are stated in the dq-frame, and the port-controlled Hamiltonian model is also obtained. A power flow analysis allows to state the control goals in terms of ohmic losses reduction, and motivates the use of the field current for the reactive power compensation. From the Hamiltonian structure, the simultaneous interconnection and damping assignment technique is used to compute the control action, which results in a controller with a simpler architecture than the standard one for this class of machines, able to cope with both positive and negative external mechanical loads and having thus bidirectional power capabilities. The robustness of the control action is also taken into account in the design procedure. Finally, the computed controller is validated via numerical simulations.",

      "abstract": "The dynamics of many physical systems can be suitably described as the form of port-controlled Hamiltonian systems. Based on this, a number of control design methods have been successfully proposed and applied in both mechanical and electrical systems. However, the rigorous structure requirements of the classical Hamilton system inevitably limit its scope of application, with the multi-machine power system considering transfer conductances as one notorious example. This study presents the pseudo-generalised Hamiltonian system, which has a more general form and a wider range of application. A new Lyapunov candidate function is proposed and proved to be a real Lyapunov function under some assumptions. Two global centralised excitation control strategies are designed by a damping injection energy balancing method and the L 2 -disturbance attenuation method, respectively. Furthermore, a multi-machine power system with transfer conductance is taken as an example to explicitly describe the application of the proposed theory. Experimental results demonstrate the effectiveness of the methodology presented in this study.",

It is assumed that the time delay parameters are unknown time-varying functions for which the only available information is about the upper bounds on their magnitude and/or variation. The stability conditions proposed here are established by constructing Lyapunov–Krasovskii stability certificates, based on the Hamiltonians of the individual port-Hamiltonian systems. The forms of the Lyapunov–Krasovskii functionals vary according to the information available on the delay parameter. It is shown how different informations on the delay are utilised to construct stability certificates.",

      "abstract": "This article studies output synchronisation of a set of non‐linear interconnected systems and general linear interconnected systems. It will be shown that output synchronisation of the systems can be achieved by adding a new coupling interconnections (consensus algorithm) to the existing interconnections if the input and output relationship of the given system is passive. The output synchronisation scheme will then be applied to a class of interconnected non‐linear systems with the special structure of port‐controlled Hamiltonian (PCH) dynamics. Since the structure of the PCH systems is restrictive, we further present a synthesis of state feedback controller to overcome the restriction. This result will be applied to multi‐machine power systems. As the second part of this paper, the output synchronisation of general linear interconnected systems will be ensured. In the case of linear interconnected systems, the synchronisation can be achieved by a decentralised observer‐based output feedback control scheme. The controller and observer gains will be calculated from decentralised linear matrix inequality conditions. Simulation tests are conducted to evaluate the performance of the proposed methods.",

      "abstract": "This study presents a practical method of neural network (NN) adaptive tracking control of uncertain port‐controlled Hamiltonian (PCH) systems. NN is used to compensate for parametric uncertainties and unlike the previous studies, the dynamics of the NN tuning law is driven by both the position as well as the velocity errors owing to the introduction of the information preserving filtering of the Hamiltonian gradient. In addition, the proposed controller achieves the ℒ2 disturbance attenuation objectives as well as preserves the PCH structure of the system in closed loop. Simulation examples demonstrate the efficacy of the proposed approach.",

First, the authors propose a sufficient condition for the dissipation of stochastic Hamiltonian systems and discuss the energy property of the systems, which will be used for the stability analysis and feedback controller design. Then, the authors show that the system is (asymptotically) stable in probability if it is (strictly) dissipative. By completing the Hamiltonian realisation of the stochastic non‐linear systems, a feedback controller is proposed to stabilise the system under the condition of dissipation and zero state detectability. For stochastic non‐linear systems subjected to external disturbances, an energy‐based <jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" xlink:href=\"graphic/cth20318-math-0003.png\" xlink:title=\"urn:x-wiley:17518644:media:cth20318:cth20318-math-0003\"/> controller was proposed by choosing the Hamiltonian function to construct a solution of Hamiltonian–Jacobi inequality.

First, the port‐Hamiltonian system is reduced based on the frequency‐interval controllability and observability Gramians. In order to reduce the computational cost, the frequency‐interval cross Gramian is utilised to yield the frequency‐interval balanced truncation method. For the symmetric port‐Hamiltonian systems, the authors prove that these two methods can generate equivalent reduced systems. Additionally, they are also devoted in exploring two structure‐preserving balanced truncation methods over time intervals, where one is based on the time interval controllability and observability Gramians and the other is based on the time interval cross Gramian. All the resulting reduced systems have port‐Hamiltonian structure, and as a consequence, they are passive. Two numerical examples are simulated to demonstrate the efficiency of the proposed methods.",

In addition to producing a new tracking control, this method also provides a re-interpretation of established results, such as computed torque control, PD+ control and Slotine-Li control. The authors also consider port-controlled Hamiltonian (PCH) systems, which are more general than EL systems. They develop a new matching equation for PCH systems so that interconnection damping assignment passivity-based control (IDA-PBC) can be applied to the control of a larger class of under-actuated PCH systems and the tracking control of some non-passive systems.",

This study studies the mathematical model of Y‐MMC and builds the port‐controlled Hamiltonian model. Since vector control scheme can hardly ensure global stability, the interconnection and damping assignment passivity‐based control (IDA‐PBC) method is applied for controller design of Y‐MMC. Three typical IDA‐PBC strategies are then proposed, featuring the asymptotical stability of the desired equilibrium. To eliminate steady‐state error, integrators are further added to the IDA‐PB controller. Different from the previous research, the proposed method enables the decoupling of different‐frequency components and the suppression of frequency leakage. Besides, the reactive power distribution coefficients are introduced to characterise the optimisation allocation of reactive power between arms. Finally, the effectiveness and superiority of the proposed control strategy are verified by both the simulation and experiment results.",

      "abstract": "Although the control strategy regarding quasi‐Z‐source inverter (qZSI) has been widely studied, the dynamic response and steady‐state accuracy of the system with a non‐linear section should be further improved. Based on this, this study proposes an energy shaping control (ESC) method based on the port‐controlled Hamiltonian (PCH) model for qZSIs. Firstly, based on the average state‐space model, the PCH model of the qZSI system is first built, which is an indispensable preprocessing for the following controller design. Based on the proposed model, the ESC method combining the interconnect matrix with damping configuration is proposed to improve the dynamic response and steady‐state accuracy, which is verified through comparing with several existing linear and non‐linear control strategies in detail. Finally, simulation and experimental results verify the effectiveness of the proposed method.",

      "abstract": "This study reveals the energy shaping port‐controlled Hamiltonian passivity‐based control (PCH‐PBC) technique for an interleaved boost power factor correction (IBPFC) converter. First, the mathematical modelling of an IBPFC converter is developed under all possible operating modes. Then, the average state‐space model of the system is established with the help of averaging state‐space technique. Further, the PCH technique is applied for controller design and the stability analysis of the proposed system is carried out. A proportional‐integral (PI) controller is integrated with the PCH‐PBC controller to achieve minimum steady‐state errors. Finally, a Simulink model of the proposed system is developed using the Simulink toolbox of MATLAB software and its performances are studied under several operating conditions and verified through experimentation. To assess the system performance in terms of efficiency and input current total harmonic distortion (THD), the comparative study is also carried out under different controllers. Based on the simulation outcomes, the proposed controller is compared with the benchmark PI controller, adaptive passivity‐based controller in terms of different control parameters. The performances of the controller are also investigated against dynamic variations at the input voltage and the load. It is observed that the proposed PCH‐PBC controller achieves robustness against the aforesaid variations.",

      "abstract": "Modular multilevel converters (MMCs) have the advantages of high‐power density and small‐harmonic distortion because of their modularity and flexibility, thus providing a new avenue for research into scalable superconducting magnetic energy storage (SMES) in renewable energy generation. This study presents coordinated control for a three‐phase four‐wire (3P4W) MMC‐based SMES system under unbalanced voltage applications. First, the positive‐ and negative‐sequence mathematical models and the port‐controlled Hamiltonian with dissipation model of the 3P4W MMC‐SMES system are established by introducing an additional path for zero‐sequence current. Second, a multi‐objective passivity‐based control strategy that can effectively improve the power quality and system robustness and eliminate both double‐frequency active and reactive power fluctuations or double‐frequency active power fluctuation and negative‐sequence current is proposed. The simulation results based on MATLAB/Simulink demonstrate the effectiveness of the proposed topology of the SMES and its control strategy.",

Furthermore, employing the modified Hamiltonian function directly as the storage function, a non-linear adaptive L2 gain control method is proposed to solve the problem of L2 gain disturbance attenuation for this Hamiltonian system with parametric perturbations.

In particular there are few results on quantitative aspects of the subject. This article considers a digital implementation problem of the passivity based control for port-controlled Hamiltonian systems. A sufficient condition for asymptotic stability is given in terms of the Hamilton-Jacobi-Isaac inequality. A more tractable sufficient condition is also shown with a reward of conservatism. The effectiveness of the proposed methods is demonstrated by numerical examples.",

A model for neutrally buoyant underwater vehicles is formulated as a PHS, and then the tracking controller is designed for the horizontal plane-surge, sway and yaw. The control design is done by formulating the error dynamics as a set-point regulation port-Hamiltonian control problem. The control design is formulated in two steps. In the first step, a static-feedback tracking controller is designed, and the second step integral action is added. The global asymptotic stability of the closed loop system is proved and the performance of the controller is illustrated using a model of an open-frame offshore underwater vehicle.",

      "abstract": "In order to improve the stability of the virtual synchronous generator (VSG) system and suppress the power oscillation, a power oscillation suppression strategy of VSG based on the finite‐time Hamiltonian method is proposed in this paper. Firstly, based on the traditional VSG control, the port‐controlled Hamiltonian with dissipation model for the active power closed‐loop circuit of the VSG grid‐connected inverter is established by considering additional control inputs. Secondly, a Hamiltonian finite‐time controller design method based on interconnection and damping assignment passivity‐based control is proposed to achieve finite‐time stability of the system. The Hamiltonian function is designed as a fractional power form by energy shaping, and the convergence speed of the system is accelerated by damping injection so that the system can quickly stabilize at the expected balance point. Then, the designed Hamiltonian function is taken as the Lyapunov function to analyse the system stability and calculate the convergence time of the VSG system. Finally, the simulation and hardware in the loop verification results show the effectiveness and great potential of this proposed controller in shortening the power oscillation time.",

      "abstract": "With the rapid integration of renewable energy sources, particularly wind and solar power, grid‐connected converters have become essential interfaces between renewable energy systems and the power grid. Among the various control strategies, grid‐following (GFL) and grid‐forming (GFM) controls are commonly used, with GFM converter playing a crucial role in enhancing grid stability. However, traditional GFM converter often rely on linear control methods, which struggle with nonlinear grid dynamics and transient faults. To address these challenges, passivity‐based control (PBC) has emerged as a promising solution for improving system stability. This paper proposes a novel passivity‐based control strategy for GFM converter, incorporating the impact of the control delays. Using the port‐controlled Hamiltonian (PCH) model, we design a feedback controller based on interconnection and damping assignment passivity‐based control (IDA‐PBC), ensuring system stability. Additionally, a frequency‐domain D‐partition method is introduced to derive the stability region and boundary of the controller under time delays, providing clear tuning criteria. The proposed strategy offers an improved approach for large‐scale renewable energy integration, enhancing converter stability and performance. The results contribute to advancing passivity‐based control theory and its practical application in renewable energy systems.",

      "abstract": "The electrodynamic loudspeaker couples mechanical, magnetic, electric and thermodynamic phenomena. The Thiele/Small (TS) model provides a low frequency approximation, combining passive linear (multiphysical or electric-equivalent) components. This is commonly used by manufacturers as a reference to specify basic parameters and characteristic transfer functions. This paper presents more refined nonlinear models of electric, magnetic and mechanical phenomena, for which fundamental properties such as passivity and causality are guaranteed. More precisely, multiphysical models of the driver are formulated in the core class of port-Hamiltonian systems (PHS), which satisfies a power balance decomposed into conservative, dissipative and source parts. First, the TS model is reformulated as a linear PHS. Then, refinements are introduced, step-by-step, benefiting from the component-based approach allowed by the PHS formalism. Guaranteed-passive simulations are proposed, based on a numerical scheme that preserves the power balance. Numerical experiments that qualitatively comply with measured behaviors available in the literature are presented throughout the paper.",

In order to achieve stabilization, we couple the system to a dynamic boundary controller, that is, a controller that acts on the system only via the boundary points<jats:italic>a</jats:italic>,<jats:italic>b</jats:italic>of the spatial domain. We use a nonlinear controller in order to capture the nonlinear behavior that realistic actuators often exhibit and, moreover, we allow the output of the controller to be corrupted by actuator disturbances before it is fed back into the system. What we show here is that the resulting nonlinear closed-loop system is input-to-state stable w.r.t. square-integrable disturbance inputs. In particular, we obtain uniform input-to-state stability for systems of order<jats:italic>N</jats:italic>= 1 and a special class of nonlinear controllers, and weak input-to-state stability for systems of arbitrary order<jats:italic>N</jats:italic>∈ ℕ and a more general class of nonlinear controllers. Also, in both cases, we obtain convergence to 0 of all solutions as<jats:italic>t</jats:italic>→<jats:italic>∞</jats:italic>. Applications are given to vibrating strings and beams.",

      "abstract": "We examine the minimization of a quadratic cost functional composed of the output and the terminal state of  infinite-dimensional evolution equations in view of existence of solutions and optimality conditions. While the initial value is prescribed, we are minimizing over all inputs within a specified convex subset of square integrable controls with values in a Hilbert space. The considered class of infinite-dimensional systems is based on the system node formulation. Thus, our developed approach includes optimal control of a wide variety of linear partial differential equations with boundary control and observation that are not well-posed in the sense that the output continuously depends on the input and the initial value. We provide an application of particular optimal control problems arising in energy-optimal control of port-Hamiltonian systems. Last, we illustrate the our  theory by two examples including a non-well-posed heat equation with Dirichlet boundary control and a wave equation on an L-shaped domain with boundary control of the stress in normal direction.",

      "abstract": "These lecture notes provide an overview of recent research on the modeling and control of smart grids using distributed algorithms. In particular, energy-based modeling of general AC power networks using the framework of port-Hamiltonian systems theory is presented, and the relevance of such a formulation for stability analysis and control design is discussed. Low-level control design aspects (at a physical layer) for DC microgrids are also considered, achieving objectives such as fair load sharing among distributed generation units and (average) voltage regulation using limited data and measurements from the system. Finally, general frameworks for the optimal control of smart grids are introduced to consider both physical and economic constraints and exploit the flexibility brought up by storage devices and demand response from the grid’s prosumers.",

      "abstract": "This paper studies the collective motion of self-driven agents in a one-dimensional space with periodic boundaries, using a stochastic Port-Hamiltonian system (PHS) with symmetric nearest-neighbor interactions and additive Brownian noise as an external input. In the case of a quadratic potential the PHS is an Ornstein-Uhlenbeck process for which we explicitly determine the distribution for any time <jats:italic>t</jats:italic> ≥ 0 and in the limit <jats:italic>t</jats:italic> → <jats:italic>∞</jats:italic>. In particular, we characterize the collective motion by showing that the agents’ positions tend to build exactly one cluster. This is confirmed in simulations that show rapid and coordinated motion among agents, driven by noise, despite the absence of a preferred direction of motion in the model. Remarkably, the theoretical properties observed in the Ornstein-Uhlenbeck process also emerge in simulations of the nonlinear model incorporating a general interaction potential.",

This note approaches the Dirac structures for infinite-dimensional systems using the theory of linear relations on Hilbert spaces. First, a kernel representation for a Dirac structure is proposed. The one-to-one correspondence between Dirac structures and unitary operators is revisited. Further, the proposed kernel representation and a scattering representation are constructively related. Several illustrative examples are also presented in the paper.",

The structure E is said to be integrable if the Courant bracket [X,Y]∊ΓE, ∀X,Y∊ΓE. Then, necessarily, one also has [X,Z]∊ΓE⊥, ∀Z∊ΓE⊥ [Vaisman, I., “Isotropic subbundles of TM⊕T*M,” Int. J. Geom. Methods Mod. Phys. 4, 487–516 (2007)]. A weak-Hamiltonian dynamical system is a vector field XH such that (XH,dH)∊ΓE⊥(H∊C∞(M)). We obtain the explicit expression of XH and of the integrability conditions of E under the regularity condition dim(prT*ME)=const. We show that the port-controlled, Hamiltonian systems (in particular, constrained mechanics) [Dalsmo, M. and van der Schaft, A. J., “On representations and integrability of mathematical structures in energy conserving physical systems,” SIAM J. Control Optim. 37, 54–91 (1998)] may be interpreted as weak-Hamiltonian systems. Finally, we give reduction theorems for weak-Hamiltonian systems and a corresponding corollary for constrained mechanical systems.",

From the variational principle, the Euler-Lagrange equations follow in an unambiguous way, but it is well known that this is not true for the Cartan form. This also has consequences on the derivation of the boundary conditions when non-trivial variations are allowed on the boundary. By posing extra conditions on the set of possible boundary terms, we exploit the degree of freedom in the Cartan form to extract physical meaningful boundary expressions. The same mathematical machinery will be applied to derive the boundary ports in a Hamiltonian representation of the partial differential equations which is crucial for energy based control approaches. Our results will be visualized for mechanical systems such as beam and plate models.",

The mode of PWM duty has been adjusted to control regenerative braking of PMSM using energy controller for the port-controlled Hamiltonian model. The simulation analysis indicates that a smooth control could be realized and the highest efficiency and the smallest current ripple could be achieved by Regenerative Braking Systems.",

      "abstract": "In view of highly decentralized and diversified power generation concepts, in particular with renewable energies, the analysis and control of the stability and the synchronization of power networks is an important topic that requires different levels of modeling detail for different tasks. A frequently used qualitative approach relies on simplified nonlinear network models like the Kuramoto model with inertia. The usual formulation in the form of a system of coupled ordinary differential equations is not always adequate. We present a new energy-based formulation of the Kuramoto model with inertia as a polynomial port-Hamiltonian system of differential-algebraic equations, with a quadratic Hamiltonian function including a generalized order parameter. This leads to a robust representation of the system with respect to disturbances: it encodes the underlying physics, such as the dissipation inequality or the deviation from synchronicity, directly in the structure of the equations, and it explicitly displays all possible constraints and allows for robust simulation methods. The model is immersed into a system of model hierarchies that will be helpful for applying adaptive simulations in future works. We illustrate the advantages of the modified modeling approach with analytics and numerical results.",

      "abstract": "In this manuscript, a general formulation of 3-dimensional compressible fluids based on the port-Hamiltonian framework is presented, both for isentropic and non-isentropic assumptions, describing the energy flux between the mechanical, chemical, and thermal domains, with an explicit characterization of the first and the second law of thermodynamics. For isentropic fluids, the conversion of kinetic energy into heat by viscous friction is considered as energy dissipation associated with the rotation and compression of the fluid. A dissipative port-Hamiltonian formulation is derived for this class of fluids, including vorticity boundary conditions in the port variables. For non-isentropic fluids, we consider a fluid mixture with multiple chemical reactions. To describe the energy fluxes, we propose a pseudo port-Hamiltonian formulation, which includes the rate of irreversible entropy creation by heat flux, chemical reaction, diffusion of matter, and viscous friction.",

First, a careful description of the mathematical tools that are needed to formulate the relevant conservation laws is given. Second, following an axiomatic approach, the two thermodynamic principles will be described, leading to a consistent description of entropy creation mechanisms on manifolds. Third, a specialization to Fourier–Navier–Stokes fluids will be carried through.",

      "abstract": "Wind energy systems can be classified into constant speed and variable speed ones. In constant speed schemes, the generator is directly connected to the electric grid. On the other hand, variable speed operation can be accomplished interposing a static converter in the energy flow between the generator and the grid, permitting a high control flexibility. The main control objectives are the maximization of the conversion efficiency and the elimination of torque oscillations propagated through the drive train. It is assumed in this paper that the most flexible part of the system lies on the turbine, constraining the control solutions to generator speed feedback. The control task is addressed from a passivity-based control viewpoint. The drive train dynamics is modelled as a port-controlled Hamiltonian system with dissipation. Then, stabilization of the desired operating point is achieved through energy shaping and damping injection. Depending on the damping matrix assignment, different control solutions are recovered. Finally, a dynamic feedback controller which preserves the system structure is proposed to improve the system performance without measuring the wind velocity.",

      "abstract": "In this paper the method of power shaping, as recently introduced for the stabilization of non-linear RLC circuits, is generalized to a larger class of systems showing similarities (and important differences) with the class of port-controlled Hamiltonian systems. Other than for port-controlled Hamiltonian systems, the stabilization of these new systems is not stymied by a ‘dissipation obstacle’ and, in fact, every power-shaping controller is power balancing as well. It is shown that the power-shaping controller can be realized as a port-controlled Hamiltonian system connected by means of a gyrator to the plant. The theoretical results are applied to the class of non-linear RLC circuits described by Brayton–Moser's equations, and a physical implementation of the controllers in terms of standard electrical circuit elements is given.",

      "abstract": "Static and Coulomb frictions are extensively used in automotive mechanical systems to control the synchronization between two shafts or two axles. Clutches, gearboxes and limited-slip differentials are some examples. This paper proposes a method for the efficient simulation of a wide class of automotive mechanical systems with static and Coulomb friction phenomena. The modelling approach is based on the port-Hamiltonian representation of the dynamic systems and the computation of the friction forces requires only the zero crossing detection. A slight approximation allows faster and sufficiently accurate simulations even without an accurate zero crossing detection. The proposed approach has been used to simulate the behaviour of a complex gearbox provided by some high level farm tractors.",

      "abstract": "Focusing on wind energy conversion system (WECS) at the doubly-fed induction generator (DFIG) control level, a novel control approach was proposed to optimise wind energy capture from consideration of physical nature and energy relationship. According to energy flowing, the WECS was divided into several multi-ports energy conversion subsystems, and the structure matrices of the subsystems were elaborately designed. Based on this, port-controlled Hamiltonian models of the subsystems were obtained, and energy-based control using the models was provided to realise the machine side and the grid side control objectives of the WECS. The approach was applied on a 2 MW WECS, and compared with classical proportional-integral (PI) controller using MATLAB/Simulink. The results show that the energy-based control not only fully satisfies both side control requirements, but also has more robust control performances for a turbulent wind than the PI control.",

      "abstract": "This article presents an energy-based coordinated control of machine- and grid-side converters in a wind energy conversion system (WECS) with a doubly-fed induction generator (DFIG) based on the theory of port-controlled Hamiltonian (PCH) system. Taking into account energy transmission in the dual PWM converter rather than treating rectification and inversion as separate parts, an integrated PCH model for the whole WECS was established from physical meanings. And depending on the new model, an energy-based coordinated control approach was proposed to meet the control requirements of the WECS with an additional objective which was to limit the DC-link voltage fluctuation. The approach was applied on a 2MW WECS, and compared with the energy-based respective control strategy using MATLAB/Simulink. The results show that the proposed control approach provides faster dynamic performance since the two converters operate with the knowledge of each other's operating status, and thus is able to smooth the power flow in the DC-link more effectively.",

      "abstract": "Interconnection and damping assignment is a controller design methodology that regulates the behaviour of dynamical systems assigning a desired port-Hamiltonian structure to the closed-loop. A key step for the application of the method is the solution of the so-called matching equation that, in the case of nonlinear systems, is a partial differential equation. It has recently been shown that for linear systems the problem boils down to the solution of a linear matrix inequality that, moreover, is feasible if and only if the system is stabilisable – making the method universally applicable. It has also been shown that if we narrow the class of assignable structures – e.g. to mechanical instead of the larger port-Hamiltonian – the problem is still translated to a linear matrix inequality, but now stabilisability is not sufficient to ensure its feasibility. It is additionally required that the uncontrolled modes are simple and lie on the jω axis, which is consistent with the considered scenario of mechanical systems without friction. The purpose of this article is to present these important results in a tutorial, self-contained form – invoking only basic linear algebra methods.",

A more appropriate definition in the context uncontrollable systems terms existence a storage function, namely function such that, along every system trajectory, its rate change at each time instant most power supplied to that time. However, even when expressible just external variables, property crucially hinges on whether or not depends variables unobservable/hidden from variables: this paper investigates key aspects both cases, and also proposes another intuitive dissipativity. These three definitions are compared: we show drawbacks one addressed by another.Dealing first with observable functions, under conditions no two poles add zero strict as frequency tends infinity, prove dissipativities part equivalent. We use behavioural approach formalising notions: behaviour set all trajectories. functions have be unobservable lossless' It known, however, result certain fallacious' examples lossless propose an dissipativity: system/behaviour called dissipative if it can embedded superbehaviour. embeddability results them resolve fallacy example termed due functions. next quite unreasonably, admits behaviours strictly antidissipative.

Both full-actuated and underactuated mechanical systems in the presence of noise are considered in this class. The proposed method gives conditions for the controller gain and design parameters under which the state remains bounded in probability. The bounded region and achieving probability are both assignable, and a stochastic Lyapunov function is explicitly provided based on a Hamiltonian structure. Although many conventional stabilisation methods assume that the noise vanishes at the origin, the proposed method is applicable to systems under persistent disturbances.",

      "abstract": "ABSTRACT A treatment of a chemical reaction network theory is given from the perspective of nonlinear network dynamics, in particular of consensus dynamics. By starting from the complex-balanced assumption, the reaction dynamics governed by mass action kinetics can be rewritten into a form which allows for a very simple derivation of a number of key results in the chemical reaction network theory, and which directly relates to the thermodynamics and port-Hamiltonian formulation of the system. Central in this formulation is the definition of a balanced Laplacian matrix on the graph of chemical complexes together with a resulting fundamental inequality. This immediately leads to the characterisation of the set of equilibria and their stability. Furthermore, the assumption of complex balancedness is revisited from the point of view of Kirchhoff's matrix tree theorem. Both the form of the dynamics and the deduced behaviour are very similar to consensus dynamics, and provide additional perspectives to the latter. Finally, using the classical idea of extending the graph of chemical complexes by a ‘zero’ complex, a complete steady-state stability analysis of mass action kinetics reaction networks with constant inflows and mass action kinetics outflows is given, and a unified framework is provided for structure-preserving model reduction of this important class of open reaction networks.",

      "abstract": "Improving the robustness, vis-à-vis matched input disturbances of interconnection and damping assignment, passivity based control (IDA-PBC) for a class of underactuated mechanical systems is addressed in this paper. The characterised class of systems is described by a Port Controlled Hamiltonian (PCH) model which represents another alternative to the classical Euler–Lagrange models for which IDA–PBC yields a smooth stabilising controller. Our main contribution consists of combining the so-called IDA-PBC controller with an adaptive control technique. Some sufficient stability conditions on matched input disturbances are given. In order to estimate the stability and performance robustness of both controllers, a stochastic robustness analysis was used. Indeed, we used the Monte Carlo simulation (MCS) based on uncertainties to analyse the behaviour of the closed-loop system. The comparison of the stability robustness between the classical IDA-PBC controller and the proposed one is then provided. As an illustration, we proposed to revisit the application of IDA-PBC controller to the inertia wheel inverted pendulum in the presence of matched disturbances. Simulation and real-time experimental results mirror the theoretical results and prove the efficiency of the proposed controller.",

      "abstract": "ABSTRACT This paper proposes a tracking-error-based multivariable control to stabilise a nonlinear system at the desired trajectory (including the open-loop unstable equilibrium manifold). The control approach is developed on the basis of feedback passivation and then applied to stabilise globally exponentially a class of free-radical polymerisation reactors. More precisely, under certain conditions the system dynamics can be rendered strictly input/output passive through the use of an appropriate input coordinate transformation. A canonical form related to the so-called port-Hamiltonian representation of passive system is consequently derived and provides physical interpretations such as dissipative/non-dissipative term and supply rate. A feedback law based on tracking-error is then designed for the global exponential stabilisation at a reference trajectory passing through the desired set-point. The theoretical developments are illustrated for polystyrene production in a continuous stirred tank reactor. Numerical simulations show that the system trajectory converges globally exponentially to the reference trajectory despite effects of disturbance.",

      "abstract": "ABSTRACT The passivity-based control (PBC) is not robust and it relies upon the system model. Moreover, partial differential equations (PDE) are encountered during its designing process which are difficult to be solved and in some cases unfeasible. In this article, reinforcement learning (RL) designs the PBC parameters via solving PDE online. RL and adaptive control are employed in order to make the nonlinear closed-loop system robust against the disturbance and model uncertainty. Through the utilisation of adaptive control technique, the passivity-based controller design along with learning could be executed as though the disturbance within the system could also be eliminated. The simulations and the comparison made with the previous methods manifest the greater advantage and superiority of the proposed method.",

      "abstract": "In this paper, the control problem of Islanded Microgrids is approached. A controller scheme that considers the necessity to assure the generation of grid-forming nodes as well as the proper operation of grid-following nodes is proposed. The main feature of the contribution is the explicit inclusion of the dynamic of the power converters existing in this kind of networks making possible the evaluation of the system performance under sudden and fast changes in the operating conditions typically found in these applications. The scheme uses only the measurement of local variables and guarantees that both voltages and currents of the network achieve the values required to satisfy a prescribed power balance imposed by the loads. The design of the proposed controller is carried out by exploiting a Port-Controlled Hamiltonian representation of the system and applying the Passivity-based Controller design methodology. The stability properties of the closed-loop system are formally proved and its usefulness is illustrated via numerical simulations.",

      "abstract": "This paper presents an adaptive control strategy for solving multi-player noncooperative differential games with dynamics modelled as general nonlinear input-state-output port-Hamiltonian systems. The proposed controller is obtained by extending an existing single-player feedback Nash strategy to N players and by using the Hamiltonian of the port-Hamiltonian system as an admissible control-Lyapunov function for each player. Necessary and sufficient conditions for the stability of the resulting controlled system are provided by employing Lyapunov stability theory. Furthermore, the N player feedback strategy is extended by adaptively weighting the individual value functions to ensure convergence to the Nash solution. Finally, numerical simulations demonstrate the effectiveness of the proposed explicit control laws.",

      "abstract": "In this paper, the problems of stabilisation and control are addressed for switched port-controlled Hamiltonian (SPCH) systems with unstable modes and actuator saturation (AS) via energy-based multiple Lyapunov functions methods. Firstly, by a switching state feedback controller with truncation-inequality techniques, the considered system is transformed into an unforced SPCH system with asymptotically stable, stable and unstable modes. Then, by developing an alternative switching law with slow/fast mode-dependent average dwell time (MDADT) switching scheme, new sufficient conditions are obtained for stabilisation of the SPCH system. Secondly, by designing a new switching feedback controller, revealing the characteristics of alternative switching signals and defining an indicative function, a new criterion for control of the SPCH systems with unstable modes and AS is achieved via the slow/fast MDADT switching scheme. Moreover, based on the obtained results and the indicative function, control conditions for the corresponding SPCH system are also derived under a slow MDADT switching scheme and a traditional average dwell time scheme, respectively. Finally, some numerical examples are given to verify the effectiveness of the proposed methods.",

      "abstract": "This article is concerned with the three-dimensional (3D) trajectory tracking control (TTC) problem for a type of autonomous underwater vehicles (AUVs) subject to unknown time-varying disturbances, input saturations, and energy constraints. With the help of port-controlled Hamiltonian (PCH) method, the system model under consideration is firstly transformed into a Hamiltonian form, and a reduced-order extended state observer (ESO) is constructed to obtain the disturbance estimate. Then, a desired state-error controller is designed to guarantee the prescribed trajectory tracking performance. Subsequently, by introducing an auxiliary system enabling to decrease the effects of input saturations, the uniformly ultimate boundedness (UUB) is achieved for the closed-loop feedback system. Finally, a simulation example is given to demonstrate the effectiveness of the developed TTC approach.",

      "abstract": "In this paper, we propose a structure-preserving model order reduction (MOR) method for parametric port-Hamiltonian (PH) systems. First, Laguerre polynomials are applied to generate the local reduced-order bases at selected parameter sample points. By expanding the system state variables in the time domain through Laguerre polynomials, we obtain the expansion coefficients for each parameter sample point. These coefficients are subsequently processed to derive the local transformation matrix necessary for the reduction procedure. We then introduce the Riemannian geometry of the Grassmann manifold and employ its tangent space for interpolation. The precomputed local reduced-order bases are organised into several groups, where the reference points are independently chosen form each group to ensure that the remaining points in each group are sufficiently proximate to their corresponding reference points. By utilising logarithmic mapping, the local reduced-order bases are transferred to the tangent spaces of the Grassmann manifold at the reference points. For a new parameter, the local reduced-order bases are interpolated within the tangent spaces of the Grassmann manifold, which facilitates the structure-preserving MOR of parametric PH systems. Finally, numerical experiments are given to validate the effectiveness of the proposed method.",

The construction exploits the intrinsic modularity of port-Hamiltonian systems to obtain a formulation of linear thermoelasticity as an interconnection of the elastodynamics and heat equations. The derived model can be readily discretized by using mixed finite elements. The discretization is structure-preserving, since the main features of the system are retained at a discrete level. The proposed model and discretization strategy are validated against a benchmark problem of thermoelasticity, the Danilovskaya problem.",

      "abstract": "This paper extends a kinetic-potential energy shaping method to stochastic mechanical port-Hamiltonian systems. The kinetic-potential energy shaping brings a new class of Lyapunov function candidates involving a cross term of the position and the momentum without solving partial differential equations for deterministic port-Hamiltonian systems. However, the conventional kinetic-potential energy shaping does not necessarily work for stochastic port-Hamiltonian systems due to energy increase by stochastic noise. Therefore, we first provide a modification properly compensated by using stochastic generalized canonical transformations. Then, two stochastic stability results are presented. The first result shows a necessary condition for stochastic asymptotic stability for an equilibrium state. The other one shows a necessary condition for stochastic bounded stability for a target state, which is not necessarily an equilibrium point. GRAPHICAL ABSTRACT",

      "abstract": "To reduce air pollution and global warming, renewable energy technologies may generate power. Wind, solar PV, and fuel cell energy are the primary sources. Solar PV system-powered brushless direct current motor (BLDC) drives are used in the automobile industry due to their importance. In this study, Sheppard–Taylor (S-T) converter and Pulse Width Modulated (PWM) Inverter-fed BLDC provide steady voltage across the BLDC motor drive independent of solar PV system power output. When renewable energy is scarce, the proposed battery-supercapacitor hybrid energy storage system (BS-HESS) provides electricity. S-T converters may be used for load matching and power processing to create energy-efficient systems and stabilize PV panel output voltage. The variable step size open circuit voltage-Maximum Power Point Tracking (VSSOCV-MPPT) technique in S-T converter switching pulses extracts maximum power from the solar PV system. This study considers the PVSWPS control function as a Port-Controlled Hamiltonian (PCH) system to continue rural growth and reduce the greatest demand and load. MATLAB/Simulink software simulates the system’s performance, and FPGA controllers validate the controller’s real-time performance.",

In particular, a flexible beam, modeled according to the Timoshenko theory and in distributed port Hamiltonian form, with a mass under gravity field connected at a free end, is considered. The control problem is approached by generalization of the concept of structural invariant (Casimir function) to the infinite dimensional case and the so-called control by interconnection technique is extended to the infinite dimensional case. In this way, finite dimensional passive controllers can stabilize distributed parameter systems by shaping their total energy, i.e., by assigning a new minimum in the desired equilibrium configuration that can be reached if a dissipation effect is introduced.",

      "abstract": "Bond graphs are primarily used in the network modeling of lumped parameter physical systems, but controller design with this graphical technique is relatively unexplored. It is shown that bond graphs can be used as a tool for certain model matching control designs. Some basic facts on the nonlinear model matching problem are recalled. The model matching problem is then associated with a particular disturbance decoupling problem, and it is demonstrated that bicausal assignment methods for bond graphs can be applied to solve the disturbance decoupling problem as to meet the model matching objective. The adopted bond graph approach is presented through a detailed example, which shows that the obtained controller induces port-Hamiltonian error dynamics. As a result, the closed loop system has an associated standard bond graph representation, thereby rendering energy shaping and damping injection possible from within a graphical context.",

      "abstract": "This contribution is dedicated to the geometric description of infinite-dimensional port Hamiltonian systems with in- and output operators. Several approaches exist, which deal with the extension of the well-known lumped parameter case to the distributed one. In this article a description has been chosen, which preserves useful properties known from the class of port controlled Hamiltonian systems with dissipation in the lumped scenario. Furthermore, the introduced in- and output maps are defined by linear differential operators. The derived theory is applied to the piezoelectric field equations to obtain their port Hamiltonian representation. In this example, the electrical field strength is assumed to act as distributed input. Finally it is shown, that distributed inputs, that are in the kernel of the input map act similarly on the system as certain boundary inputs.",

The methodology is based on the first principle, conservation laws and constitutive closure relations. The latter are the phenomenological laws relating fluxes and thermodynamic forces. Then instantaneous power conservation appears naturally as a geometric interconnection structure called Dirac structure. The multi-level case (several macroscopic spatial scales) is investigated with the assumption that the spatial scales are separated and may be considered as two distinct phases. In this case, it is shown that both the interconnection coupling within a phase and the multi-level interconnection coupling are Dirac structures.",

      "abstract": "The port-Hamiltonian modelling framework is extended to a class of systems containing memristive elements and phenomena. First, the concept of memristance is generalised to the same generic level as the port-Hamiltonian framework. Second, the underlying Dirac structure is augmented with a memristive port. The inclusion of memristive elements in the port-Hamiltonian framework turns out to be almost as straightforward as the inclusion of resistive elements. Although a memristor is a resistive element, it is also a dynamic element since the associated Ohmian laws are rather expressed in terms of differential equations. This means that the state space manifold, as naturally defined by the storage elements, is augmented by the states associated with the memristive elements. Hence the order of complexity is, in general, defined by the number of storage elements plus the number of memristors in the system. Apart from enlarging our repertoire of modelling building blocks, the inclusion of memristive elements in the existing port-Hamiltonian formalism possibly opens up new ideas for controller synthesis and design.",

      "abstract": "A reduction method that preserves geometric structure and energetic properties of non-linear distributed parameter systems is presented. It is stated as a general pseudospectral method using approximation spaces generated by polynomials bases. It applies to Hamiltonian formulations of distributed parameter systems that may be derived for hyperbolic systems (wave equation, beam model, shallow water model) as well as for parabolic ones (heat or diffusion equations, reaction–diffusion models). It is defined in order to preserve the geometric symplectic interconnection structure (Stokes–Dirac structure) of the infinite-dimensional model by performing exact differentiation and by a suitable choice of port variables. This leads to a reduced port-controlled Hamiltonian finite-dimensional system of ordinary differential equations. Moreover, the stored and dissipated power in the reduced model are approximations of the distributed ones. The method thus allows the direct use of thermodynamics phenomenological constitutive equations for the design of passivity-based or energy-shaping control techniques.",

      "abstract": "This article deals with the geometric analysis of the evolutionary and the polysymplectic approach in first-order Hamiltonian field theory. Based on a variational formulation in the Lagrangian picture, two possible counterparts in a Hamiltonian formulation are discussed. The main difference between these two approaches, which are important for the application, is besides a different bundle construction, the different Legendre transform as well as the analysis of the conserved quantities. Furthermore, the role of the boundary conditions in the Lagrangian and in the Hamiltonian pictures will be addressed. These theoretical investigations will be completed by the analysis of several examples, including the wave equation, a beam equation and a special subclass of continuum mechanics in the presented framework.",

Based on the matrix measure approach, sufficient conditions on the original system matrices are derived. Once they are fulfilled, the stability of each of the reduced models is guaranteed as well as that of the parametric model resulting from interpolation. In addition, it is shown that these sufficient conditions are met by port-Hamiltonian systems and by a relevant set of second-order systems obtained by the finite element method. The new approach is illustrated by two numerical examples.",

Electromagnetic field and material domain balance equations are expressed in covariant forms, together with the magneto-hydrodynamics interconnection structure connecting them together. The balance equations for the entropy, mass and momentum, as well as closure equations in the material domain, are derived from the Boltzmann equation (kinetic theory). The Gibbs–Duhem equation is used to compute the irreversible entropy source term and to define the interdomain ℜ-field of the model. All derived interdomain couplings in the material domain are represented using Dirac and Stokes–Dirac structures and the resistivity ℜ-field structure.

      "abstract": "ABSTRACT The use of beams and similar structural elements is finding increasing application in many areas including micro and nanotechnology devices. For the purpose of buckling analysis and control, it is essential to account for nonlinear terms in the strains while modelling these flexible structures. Further, the Poisson’s effect can be accounted in modelling by the use of a two-dimensional stress–strain relationship. This paper studies the buckling effect for a slender, vertical beam (in the clamped-free configuration) with horizontal actuation at the fixed end and a tip-mass at the free end. Including also the inextensibility constraint of the beam, the equations of motion are derived. A preliminary modal analysis of the system has been carried out to describe candidate post-buckling configurations and study the stability properties of these equilibria. The vertical configuration of the beam under the action of gravity is without loss of generality, since the objective is to model a potential field that determines the equilibria. Neglecting the inextensibility constraint, the equations of motion are then casted in port-Hamiltonian form with appropriately defined flows and efforts as a basis for structure-preserving discretization and simulation. Finally, the finite-dimensional model is simulated to obtain the time response of the tip-mass for different loading conditions.",

It is based on the projection which makes use of the symmetries and on the preservation of the ‘natural’ power pairing for the considered system. Thanks to this reduction, an Interconnection and Damping Assignment Passivity Based Control (IDA-PBC-like) synthesis for infinite dimensional port-Hamiltonian systems is investigated. As for the finite dimensional case, a feedback control transforms the original model into a closed-loop target Hamiltonian model. Both distributed control and boundary control are used. The finite rank distributed control is determined to solve an average IDA-PBC matching equation. A backstepping boundary control is used to stabilize the matching error. The control model chosen to illustrate the approach is the so-called resistive diffusion equation for the radial diffusion of the poloidal magnetic flux.",

      "abstract": "ABSTRACT This paper illustrates a general synthesis methodology of asymptotic stabilizing, energy-based, boundary control laws that are applicable to a large class of distributed port-Hamiltonian systems. The methodological results are applied on a simplified model of an isothermal tubular reactor. Due to the presence of diffusion and convection, such example, even if relatively easy from a computational point of view, is not trivial. The idea here is to design a state feedback law able to perform the energy-shaping task, i.e. able to render the closed-loop system a port-Hamiltonian system with the same structure, but characterized by a new Hamiltonian with a unique and isolated minimum at the equilibrium. Asymptotic stability is then obtained via damping injection on the boundary and is a consequence of the LaSalle’s Invariance Principle in infinite dimensions.",

Two examples are studied: the transmission line and a non-isothermal reaction diffusion process. The proposed approach uses thermodynamic variables in order to define the infinite-dimensional interconnection structure linking the different phenomena. A presentation is given for one-dimensional spatial domain. For the transmission line, the Hamiltonian is the total energy and for the reaction diffusion process it is the enthalpy or the opposite of entropy.",

Despite their popularity, no publication has appeared which adapts them for use with port-based modelling tools such as bond graphs, linear graphs or port-Hamiltonian theory. In this paper, we present – for scleronomic systems – a momentum form of Kane’s equations, fully compatible with port-based modelling methods. When applied to holonomic systems using coordinate derivatives, the momentum form of Kane’s equations is an efficient alternative to Lagrange’s equations, providing a momentum formulation without the need to assemble and differentiate the system kinetic co-energy function. When applied to holonomic or nonholonomic systems using generalized speeds, a rotational decomposition of the generalized forces leads to a convenient set of matrix equations of motion, for which a system-level multibond graph interpretation is given. Heuristics are provided for selection of generalized speeds which, for systems with open-chain kinematics, produce a block-diagonal mass matrix and reduce the complexity of the equations from order- to order-. For scleronomic systems, the momentum formulation retains all analysis capabilities offered by the original acceleration formulation. Two example problems are solved with the momentum formulation, including the nonholonomic rolling thin disk.",

      "abstract": "ABSTRACT Stability of power networks is an increasingly important topic because of the high penetration of renewable distributed generation units. This requires the development of advanced techniques for the analysis and controller design of power networks. Although there are widely accepted reduced-order models to describe the power network dynamics, they are commonly presented without details about the reduction procedure. The present article aims to provide a modular model derivation of multi-machine power networks. Starting from first-principle fundamental physics, we present detailed dynamical models of synchronous machines and clearly state the underlying assumptions which lead to some of the standard reduced-order multi-machine models. In addition, the energy functions for these models are derived, which allows to represent the multi-machine systems as port-Hamiltonian systems. Moreover, the systems are proven to be shifted passive, which permits for a power-preserving interconnection with other passive components. Graphical Abstract",

The aim of this paper is to show how these vibrations can be modelled within the framework of port-Hamiltonian systems. It turns out that two port-Hamiltonian descriptions in physical variables are possible. The first one is in descriptor form, whereas the second one has a non-local Hamiltonian density. In addition, it is shown that under appropriate boundary conditions these models possess a unique solution which is non-increasing in the corresponding ‘energy’, i.e., the associated infinitesimal generator generates a contraction semigroup on a Hilbert space, whose norm is directly linked to the Hamiltonian.",

      "abstract": "ABSTRACT A simple and scalable finite-dimensional model based on the port-Hamiltonian framework is proposed to describe the fluid–structure interaction in tubes with time-varying geometries. For this purpose, the moving tube wall is described by a set of mass-spring-damper systems while the fluid is considered as a one-dimensional incompressible flow described by the average momentum dynamics in a set of incompressible flow sections. To couple these flow sections small compressible volumes are defined to describe the pressure between two adjacent fluid sections. The fluid-structure coupling is done through a power-preserving interconnection between velocities and forces. The resultant model includes external inputs for the fluid and inputs for external forces over the mechanical part that can be used for control or interconnection purposes. Numerical examples show the accordance of this simplified model with finite-element models reported in the literature.",

      "abstract": "ABSTRACT We investigate an energy-based formulation of the two-field poroelasticity model and the related multiple-network model as they appear in geosciences or medical applications. We propose a port-Hamiltonian formulation of the system equations, which is beneficial for preserving important system properties after discretization or model-order reduction. For this, we include the commonly omitted second-order term and consider the corresponding first-order formulation. The port-Hamiltonian formulation of the quasi-static case is then obtained by (formally) setting the second-order term zero. Further, we interpret the poroelastic equations as an interconnection of a network of submodels with internal energies, adding a control-theoretic understanding of the poroelastic equations.",

      "abstract": "ABSTRACT Port-Hamiltonian systems theory provides a structured approach to modelling, optimization and control of multiphysical systems. Yet, its relationship to thermodynamics seems to be unclear. The Hamiltonian is traditionally thought of as energy, although its meaning is exergy. This insight yields benefits: 1. Links to the GENERIC structure are identified, making it relatively easy to borrow ideas from a popular nonequilibrium thermodynamics framework. 2. The port-Hamiltonian structure combined with a bond-graph syntax is expected to become a main ingredient in thermodynamic optimization methods akin to exergy analysis and beyond. The intuitive nature of exergy and diagrammatic language facilitates interdisciplinary communication that is necessary for implementing sustainable energy systems and processes. Port-Hamiltonian systems are cyclo-passive, meaning that a power-balance equation immediately follows from their definition. For exergetic port-Hamiltonian systems, cyclo-passivity is synonymous with degradation of energy and follows from the first and the second law of thermodynamics being encoded as structural properties.",

However, the underlying mathematical coupling structures have not been thoroughly investigated. In this work, the port-Hamiltonian formalism is applied to the conjugate heat transfer problem in gas turbine blades. A mathematical model based on common engineering simplifications is constructed and further simplified to reduce complexity and focus on the coupling structures of interest. The model is then cast as a port-Hamiltonian system and examined for stability and well posedness.",

After discretization, we combine the laws of continuum mechanics for solids and fluids within a unified port-Hamiltonian (pH) modelling approach by adapting the equations through an appropriate coordinate transformation on the second-order level. The high-dimensionality of the resulting system is reduced by model order reduction. The article focuses on pH-systems in different state transformations, a variety of basis generation techniques as well as structure-preserving model order reduction approaches that are independent from the projection basis. As main contribution, a thorough comparison of these method combinations is conducted. In contrast to typical frequency-based simulations in acoustics, transient time simulations of the system are presented. The approach is embedded into a straightforward workflow of sophisticated commercial software modelling and flexible in-house software for multi-physics coupling and model order reduction.",

Our method exploits the structural properties of the Rosenbrock system matrix for this system class and utilizes condensed forms which often arise in applications and reveal the solution behaviour of a system. Provided that the original system has such a form, our method produces reduced-order models (ROMs) of minimal dimension, which tangentially interpolate the original model’s transfer function and are guaranteed to be again in pH-DAE form. This allows the ROM to be safely coupled with other dynamical systems when modelling large system networks, which is useful, for instance, in electric circuit simulation.",

      "abstract": "We consider the dynamics of an elastic continuum under large deformation but small strain. Such systems can be described by the equations of geometrically nonlinear elastodynamics in combination with the St. Venant-Kirchhoff material law. The velocity-stress formulation of the problem turns out to have a formal port-Hamiltonian structure. In contrast to the linear case, the operators of the problem are modulated by the displacement field which can be handled as a passive variable and integrated along with the velocities. A weak formulation of the problem is derived and essential boundary conditions are incorporated via Lagrange multipliers. This variational formulation explicitly encodes the transfer between kinetic and potential energy in the interior as well as across the boundary, thus leading to a global power balance and ensuring passivity of the system. The particular geometric structure of the weak formulation can be preserved under Galerkin approximation via appropriate mixed finite elements. In addition, a fully discrete power balance can be obtained by appropriate time discretization. The main properties of the system and its discretization are shown theoretically and demonstrated by numerical tests.",

      "abstract": "This paper reveals energy shaping passivity-based control methodology for a three-level (TL) Ćuk PFC converter. The proposed control methodology is based on the dynamic model of the system along with the idea of energy shaping and damping injection. First, a dynamic model of the TL Ćuk PFC converter is developed using the port-controlled Hamiltonian formulation and the state-space averaging technique. Then, the PCH control technique is implemented in the system and the stability analysis is carried out. In order to eliminate the steady state error, a PI controller is integrated with the PCH-PBC control scheme. Further, the performances of aforesaid system are investigated for battery charging application with the help of MATLAB/Simulink. To validate the simulation study, a prototype model of TL Ćuk PFC converter with proposed controller is built using OP-5142 real-time simulator and test results are recorded. Furthermore, the power quality features of TL Ćuk PFC converter are assessed through monitoring of input current THD under different operating conditions. To assess the system performance in terms of efficiency, input p.f., input current THD, and controller parameters, the proposed controller is compared with benchmark PI controller under dynamic variations at the input voltage and the load.",

      "abstract": "In this paper, we propose a new second-order sliding mode controller for mechanical port-Hamiltonian systems. This paper proposes a passivity-based sliding mode controller based on kinetic-potential energy shaping (KPES). So far this type of controller was only able to achieve first-order sliding mode control, since the KPES allows one to embed a subsystem whose dimension is the same as that of the input into the closed-loop system. This paper extends the KPES to incorporate a higher-order subsystem in the closed-loop system, which enables us to obtain the subsystem that can realize second-order sliding mode control. The proposed controller is integration of a passivity-based controller and a second-order sliding mode controller which does not cause undesirable chattering phenomena. It ensures finite-time convergence of the subsystem and asymptotic stability of the entire closed-loop system by utilizing two Lyapunov functions. Moreover, due to the design freedom in selecting a Lyapunov function candidate of the KPES, it can deal with several control objectives including trajectory tracking control. A numerical example demonstrates the effectiveness of the proposed method.",

In this approach, the Hamiltonian function, which is the sum of kinetic and potential energies of the system, is considered as the Lyapunov function for stability analysis. The stability analysis is done based on the port-controlled Hamiltonian (PCH) model. In this regard, two theorems are given and proved that the proposed controllers lead to disturbance attenuation for both absolutely known system model and unknown ones with parametric uncertainties. In the case of parametric uncertainties, the energy-based controller has an adaptive approach. Performance of proposed controllers is illustrated through simulations taken on a 2-link robot manipulator system, which validate the theoretical achievements of this paper.",

      "abstract": "Control theory usually finds no suitable place in the education of physics. The port-Hamiltonian framework, which generalizes the formalism of Hamiltonian mechanics, provides a physics-based control strategy. This framework is also promising in the education of physicists in control theory. In this paper, we use the port-Hamiltonian framework to reformulate a physics system and introduce the physics-based control strategy, including the energy, dissipation, and structure assignments. The closed-loop Hamiltonian is a candidate of the Lyapunov function, which guarantees the global stability of the closed-loop system. These physics-based control strategies are illustrated using the Duffing oscillator and the Lorenz system. We also provide port-Hamiltonian descriptions for two examples in celestial mechanics.",

We discuss how control laws should be designed to minimize the effect of small variations in the generators terminal conditions, i.e. local control that does not have access or knowledge to a model of the rest of the system. For analysis purpose we present a linearized generator model and apply a full state feedback control consisting of both regulation of the generator flux and rotational dynamics.",

      "abstract": "Port-Hamiltonian systems are pertinent representations of many nonlinear physical systems. In this study, we formulate and analyse a general class of stochastic car-following models with a systematic port-Hamiltonian structure. The model class is a generalisation of classical car-following approaches, including the <jats:italic>optimal velocity model</jats:italic> of Bando <jats:italic>et al</jats:italic> (1995 <jats:italic>Phys. Rev.</jats:italic> E <jats:bold>51</jats:bold> 1035), the <jats:italic>full velocity difference model</jats:italic> of Jiang <jats:italic>et al</jats:italic> (2001 <jats:italic>Phys. Rev.</jats:italic> E <jats:bold>64</jats:bold> 017101), and recent stochastic following models based on the Ornstein–Uhlenbeck process. In contrast to traditional models where the interaction is totally asymmetric (i.e. depending only on the speed and distance to the predecessor), the port-Hamiltonian car-following model also depends on the distance to the follower. We determine the exact stability condition of the finite system with <jats:italic>N</jats:italic> vehicles and periodic boundaries. The stable system is ergodic with a unique Gaussian invariant measure. Other properties of the model are studied using numerical simulation. It turns out that the Hamiltonian component improves the flow stability and reduces the total energy in the system. Furthermore, it prevents the problematic formation of stop-and-go waves with oscillatory dynamics, even in the presence of stochastic perturbations.",

      "abstract": "A control strategy based on Hamiltonian energy theory is proposed for the wind farm with flywheel energy storage system (FESS). The control of the ratio consensus of the flywheel energy storage system is realized by adjusting the speed of the flywheel energy storage unit. First, the port-controlled Hamilton (PCH) model of the flywheel energy storage unit is established, and the port-controlled Hamiltonian with dissipation (PCH-D) model is obtained by using the feedback stabilization principle of the PCH system. Then, the problem of the ratio consensus control of the flywheel energy storage system is investigated. In order to realize that all flywheel energy storage units can store and release energy at the same rate, the control strategy of Hamilton energy shaping is applied to adjust the speed of flywheel energy storage units. Finally, the effectiveness of the proposed control strategy is verified by simulations.",

In this paper, a model of TWW with features, including space-saving, four to two-wheel transformation, and adjustable seat height is proposed to increased mobility and independence of the user. Then, the mathematical model of a TWW in its balanced mode is derived. The model is based on the total energy in the system. The system is divided into subsystems whereby the interconnections which exist are utilized. The nonlinearity of the model is preserved using port-controlled Hamiltonian (PCH) system and made to advantage.

      "abstract": "This paper presents an analysis of mobility on an over-actuated Remotely Operated Vehicle (ROV) that becomes under-actuated due to multiple actuator faults of different types of degradation. The analysis is developed on a regulation control problem, including modeling and robust control design. The dynamic model is formulated using a Port-Hamiltonian formalism, emphasizing energy conservation and passivity. The control strategy is developed through a Control by Interconnection (CbI) structure to regulate the ROV posture as an interconnected energy-based system. Singular Value Decomposition (SVD) is employed to assess mobility effectiveness in each spatial direction. Quadratic Programming (QP) is used for realistic control allocation under actuator constraints and fault conditions, highlighting the direction with reduced effectiveness for improving performance in a complete posture regulation task. The simulation results validate control allocation based on QP, demonstrating its robustness in maintaining ROV stability and achieving posture regulation under various fault scenarios. It has been shown that the ROV topology under study supports two individual thruster faults and still achieves a 3D target, and the resulting reduced directions can be enhanced by QP allocation; for instance, yaw error is improved by nearly 50% compared with the SVD method, demonstrating its ability to redistribute control forces efficiently while preserving closed-loop stability. Furthermore, computational performance analysis confirms the approach’s real-time feasibility for experimental implementation, with the QP solver operating at about 1 ms per iteration.",

      "abstract": "Abstract Soft robots are machines, and like all machines their function is to convert energy from one form into another to perform tasks. One key figure of merit for machines is their efficiency, which is defined as the ratio of task-oriented work out to total energy in. All soft robots convert stored energy (from e.g., batteries, pressurized gas, chemicals) into task-oriented work (picking up objects, locomoting, jumping). These systems are complex hybrids of chemical, mechanical, pneumatic, hydraulic, and electrical components. This complexity makes it difficult to analyze and measure their total efficiency and to identify the sources of energy loss between chemical, electrical, and mechanical domains. As the field of soft robotics matures, the design-flow process will shift from one in which building is central to one in which simulation takes precedence. That is, there is a shift from an empirical experimental methodology toward a well-characterized engineering workflow. At this point, questions such ...",

When the system is subject to perturbations, passivity or stability may be lost. To make the system robust, we use the freedom in the representation to characterize and construct optimally robust representations in the sense that the distance to non-passivity is maximized with respect to an appropriate matrix norm. We link this construction to the solution set of certain linear matrix inequalities defining passivity of the transfer function. We present an algorithm to compute a nearly optimal representation using an eigenvalue optimization technique. We also briefly consider the problem of finding the nearest passive system to a given non-passive one.",

      "abstract": "The notion of implicit port-Lagrangian systems for nonholonomic mechanics was proposed in Yoshimura &amp; Marsden (2006a, J. Geom. Phys., 57, 133–156; 2006b, J. Geom. Phys., 57, 209–250; 2006c, Proc. of the 17th International Symposium on Mathematical Theory of Networks and Systems, Kyoto) as a Lagrangian analogue of implicit port-Hamiltonian systems. Such port-systems have an interconnection structure with ports through which power is exchanged with the exterior and which can be modeled by Dirac structures. In this paper, we present the notions of implicit port-Lagrangian systems and port-Dirac dynamical systems in nonequilibrium thermodynamics by generalizing the Dirac formulation to the case allowing irreversible processes, both for closed and open systems. Port-Dirac systems in nonequilibrium thermodynamics can be also deduced from a variational formulation of nonequilibrium thermodynamics for closed and open systems introduced in Gay-Balmaz &amp; Yoshimura (2017a, J. Geom. Phys., 111, 169–193; 2018a, Entropy, 163, 1–26). This is a type of Lagrange–d’Alembert principle for the specific class of nonholonomic systems with nonlinear constraints of thermodynamic type, which are associated to the entropy production equation of the system. We illustrate our theory with some examples such as a cylinder-piston with ideal gas, an electric circuit with entropy production due to a resistor and an open piston with heat and matter exchange with the exterior.",

      "abstract": "The free surface motion in moving containers is an important physical phenomenon for many engineering applications. One way to model the free surface motion is by employing shallow water equations (SWEs). The port-Hamiltonian systems formulation is a powerful tool that can be used for modeling complex systems in a modular way. In this work, we extend previous work on SWEs using the port-Hamiltonian formulation, by considering the two-dimensional equations under rigid body motions. The resulting equations consist of a mixed-port-Hamiltonian system, with finite and infinite-dimensional energy variables and ports. 2000 Math Subject Classification: 34K30, 35K57, 35Q80, 92D25",

      "abstract": "The port-Hamiltonian (pH) theory for distributed parameter systems has developed greatly in the past two decades. The theory has been successfully extended from finite-dimensional to infinite-dimensional systems through a lot of research efforts. This article collects the different research studies carried out for distributed pH systems. We classify over a hundred and fifty studies based on different research focuses ranging from modeling, discretization, control and theoretical foundations. This literature review highlights the wide applicability of the pH systems theory to complex systems with multi-physical domains using the same tools and language. We also supplement this article with a bibliographical database including all papers reviewed in this paper classified in their respective groups.",

      "abstract": "In this paper, the control problem of microgrids (MGs)operating in islanded mode is approached from a passivity-based control perspective. A control scheme is proposed that, relying only on local measurements for the power converters included in the network representation, achieves both voltage regulation and power balance in the network through the generation of grid-forming and grid-following nodes. From the mathematical perspective, the importance of the contribution lies in the feature that, exploiting a port-controlled Hamiltonian representation of the MG, the closed-loop system’s stability properties are formally proved using arguments from the theory of non-linear dynamical systems. Fundamental for this achievement is the decomposition of the system into subsystems that require a control law and another whose variables can evolve in a free way. From the practical viewpoint, the advantage of the proposed controller lies in the feature that the power demanded by the loads is satisfied without neither computing its specific value nor solving the non-linear algebraic equations given by the power flow, avoiding the computational burden associated with this task. The usefulness of the scheme is illustrated via a numerical simulation that includes practical considerations.",

A discretization scheme is proposed, and a set of precise basis functions are given in order to obtain a structure-preserving finite-dimensional port- Hamiltonian approximation of the two-dimensional vibro-acoustic system. Using the closed-loop structural invariants of the approximated system an energy-Casimir controller is derived. The performance of the proposed discretization scheme and the controller is shown by means of numerical simulations.",

      "abstract": "Lumped elements models of vocal folds are relevant research tools that can enhance the understanding of the pathophysiology of many voice disorders. In this paper, we use the port-Hamiltonian framework to obtain an energy-based model for the fluid–structure interactions between the vocal folds and the airflow in the glottis. The vocal fold behavior is represented by a three-mass model and the airflow is described as a fluid with irrotational flow. The proposed approach allows to go beyond the usual quasi-steady one-dimensional flow assumption in lumped mass models. The simulation results show that the proposed energy-based model successfully reproduces the oscillations of the vocal folds, including the collision phenomena, and it is useful to analyze the energy exchange between the airflow and the vocal folds.",

      "abstract": "This paper presents a structure-preserving spatial discretization method for distributed parameter port-Hamiltonian systems. The class of considered systems are hyperbolic systems of two conservation laws in arbitrary spatial dimension and geometries. For these systems, a partitioned finite element method (PFEM) is derived, based on the integration by parts of one of the two conservation laws written in weak form. The non-linear one-dimensional shallow-water equation (SWE) is first considered as a motivation example. Then, the method is investigated on the example of the non-linear two-dimensional SWE. Complete derivation of the reduced finite-dimensional port-Hamiltonian system (pHs) is provided and numerical experiments are performed. Extensions to curvilinear (polar) coordinate systems, space-varying coefficients and higher-order pHs (Euler–Bernoulli beam equation) are provided.",

We consider the $\\mathcal{H}_2$ optimal model order reduction problem of the general linear port-Hamiltonian systems. The problem is formulated as an optimization problem on the product manifold, which is composed of the set of skew symmetric matrices, the manifold of the positive definite matrices, the manifold of the positive semidefinite matrices with fixed rank and the Euclidean space. To solve the optimal problem, the Riemannian geometry of the product manifold is given. Moreover, the Riemannian gradient and the Riemannian Hessian of the objective function are derived. Furthermore, we propose the Riemannian trust-region method for the optimization problem and introduce the truncated conjugate gradient method to solve the trust-region subproblem. Finally, the numerical experiments illustrate the efficiency of the proposed method.",

      "abstract": "This paper models and simulates conservative linear acoustic propagation in axisymmetric pipes with time–space-dependent cross-sections. It extends the horn equation to moving-wall bores. The physical equations (partial differential equations) satisfy a power balance, allowing their formulation as a Port-Hamiltonian system. A two-step numerical method is proposed, which preserves mass, momentum and power conservation in discrete domains. Spatial discretization yields a system of Ordinary Differential Equations (ODE) that satisfies known acoustic characteristics for static walls and ensures power-balanced propagation for controlled dynamic walls. Time discretization via the discrete-gradient method results in a discrete time–space model. Simulations validate conservative propagation and resonances for static walls and capture dynamic vocal tract acoustics during articulation.",

      "abstract": "We discuss a class of linear control problems in a Hilbert space setting. This class encompasses such diverse systems as port-Hamiltonian systems, Maxwell's equations with boundary control or the acoustic equations with boundary control and boundary observation. The boundary control and observation acts on abstract boundary data spaces such that the only geometric constraint on the underlying domain stems from requiring a closed range constraint for the spatial operator part, a requirement which for the wave equation amounts to the validity of a Poincare–Wirtinger-type inequality. We also address the issue of conservativity of the control problems under consideration.",

      "abstract": "It is well documented that shaping the energy of finite-dimensional port-Hamiltonian systems by interconnection is severely restricted due to the presence of dissipation. This phenomenon is usually referred to as the dissipation obstacle. In this paper, we show the existence of dissipation obstacle in infinite dimensional systems. Motivated by this, we present the Brayton–Moser formulation, together with its equivalent Dirac structure. Analogous to finite dimensional systems, identifying the underlying gradient structure is crucial in presenting the stability analysis. We elucidate this through an example of Maxwell’s equations with zero energy flows through the boundary. In the case of mixed-finite and infinite-dimensional systems, we find admissible pairs for all the subsystems while preserving the overall structure. We illustrate this using a transmission line system interconnected to finite dimensional systems through its boundary. This ultimately leads to a new passive map, using this we solve a boundary control problem, circumventing the dissipation obstacle.",

      "abstract": "We consider the simulation of barotropic flow of gas in long pipes and pipe networks. Based on a Hamiltonian reformulation of the governing system, a fully discrete approximation scheme is proposed using mixed finite elements in space and an implicit Euler method in time. Assuming the existence of a smooth subsonic solution bounded away from vacuum, a full convergence analysis is presented based on relative energy estimates. Particular attention is paid to establishing error bounds that are uniform in the friction parameter. As a consequence, the method and results also cover the parabolic problem arising in the asymptotic large friction limit. The error estimates are derived in detail for a single pipe, but using appropriate coupling conditions and the particular structure of the problem and its discretization, the main results directly generalize to pipe networks. Numerical tests are presented for illustration.",

      "abstract": "A port-Hamiltonian (pH) system formulation is a geometrical notion used to formulate conservation laws for various physical systems. The distributed parameter port-Hamiltonian formulation models infinite dimensional Hamiltonian dynamical systems that have a nonzero energy flow through the boundaries. In this paper, we propose a novel framework for discontinuous Galerkin (DG) discretizations of pH-systems. Linking DG methods with pH-systems gives rise to compatible structure preserving semidiscrete finite element discretizations along with flexibility in terms of geometry and function spaces of the variables involved. Moreover, the port-Hamiltonian formulation makes boundary ports explicit, which makes the choice of structure and power preserving numerical fluxes easier. We state the Discontinuous Finite Element Stokes–Dirac structure with a power preserving coupling between elements, which provides the mathematical framework for a large class of pH discontinuous Galerkin discretizations. We also provide an a priori error analysis for the port-Hamiltonian discontinuous Galerkin Finite Element Method (pH-DGFEM). The port-Hamiltonian discontinuous Galerkin finite element method is demonstrated for the scalar wave equation showing optimal rates of convergence.",

      "abstract": "In this article, we propose a model for a stand-alone hybrid distributed generation system. In this model, the input sources are distributed DC sources like solar panels or batteries. The idea behind this network framework is to introduce a hybrid DC/AC network, feasible for small and remotely located areas with stand-alone DC grids, in the vicinity of larger towns requiring a functional AC connection. The behaviour of the system in the steady state is analysed, and the network is mathematically represented with port-controlled Hamiltonian modelling. Stabilization to the desired voltage, both AC as well as DC, is attained with nonlinear passivity-based control taking into consideration not only the energy characteristics but also the inherent physical structure.",

Specifically, using a stochastic dissipativity, losslessness and accumulativity theory, we develop a nonlinear stochastic port-Hamiltonian system model characterized by energy conservation and entropy non-conservation laws that are consistent with statistical thermodynamic principles. In particular, we show that the difference between the average stored system energy and the average supplied system energy for our stochastic thermodynamic model is a martingale with respect to the system filtration, whereas the difference between average system entropy production and the average system entropy consumption is a submartingale with respect to the system filtration.

      "abstract": "Accurately learning the temporal behavior of dynamical systems requires models with well-chosen learning biases. Recent innovations embed the Hamiltonian and Lagrangian formalisms into neural networks and demonstrate a significant improvement over other approaches in predicting trajectories of physical systems. These methods generally tackle autonomous systems that depend implicitly on time or systems for which a control signal is known a priori. Despite this success, many real world dynamical systems are nonautonomous, driven by time-dependent forces and experience energy dissipation. In this study, we address the challenge of learning from such nonautonomous systems by embedding the port-Hamiltonian formalism into neural networks, a versatile framework that can capture energy dissipation and time-dependent control forces. We show that the proposed port-Hamiltonian neural network can efficiently learn the dynamics of nonlinear physical systems of practical interest and accurately recover the underlying stationary Hamiltonian, time-dependent force, and dissipative coefficient. A promising outcome of our network is its ability to learn and predict chaotic systems such as the Duffing equation, for which the trajectories are typically hard to learn.",

      "abstract": "Purpose                    This study aims to develop a systematic and efficient method for modeling and reducing the computational complexity of the Maxwell equations in 2D. By maintaining the port-Hamiltonian structure in both the full order model (FOM) and reduced-order model (ROM), this approach ensures that the essential dynamical properties are preserved. The ultimate goal is to create a reduced order model that is suitable for rapid simulations, control and analysis in electromagnetic applications, such as waveguides, which involve boundary control and observation, as well as interface discontinuities.                                                        Design/methodology/approach                    This research introduces an ROM procedure for the 2D Maxwell equations within a port-Hamiltonian framework. Using a mixed finite element method, the high-fidelity FOM is generated, which retains the original structure of the Maxwell equations. Model reduction is then achieved through the Loewner framework, allowing for a low-complexity model that is computationally efficient while preserving the port-Hamiltonian properties. A lifting operator is employed to recover the FOM’s internal variables from the reduced model, validating the accuracy of the ROM in reproducing the FOM’s dynamic behavior.                                                        Findings                    The proposed methodology effectively reduces the dimension of the Maxwell system by approximately 35 times, significantly decreasing computational time while maintaining high fidelity in the key output responses. Simulation results demonstrate that the reduced model accurately replicates the full order model’s dynamics and power balance. The approach also highlights the advantages of using a port-Hamiltonian structure for energy tracking, with ROMs exhibiting only minor discrepancies due to truncation. The findings validate the ROM as a reliable and efficient approximation of the original high-dimensional system, suitable for complex electromagnetic configurations.                                                        Originality/value                    This work provides a novel approach to reducing the 2D Maxwell equations within a port-Hamiltonian framework, preserving essential structure and dynamical properties. By leveraging the Loewner framework with a unique focus on passivity preservation, the method offers a practical solution for efficient simulation and control in electromagnetic systems. This ROM methodology, with its reduced computational burden and enhanced accuracy, is valuable for applications in electromagnetic field simulations and control design, where high computational efficiency and structure preservation are critical [1].",

The design methodology builds upon some developments on passivity-based stabilization of port-controlled Hamiltonian (PCH) systems reported in Ortega et al. (1999) and Maschke et al. (1998). We first write the system dynamics in PCH form, with the Hamiltonian function being the total mass. Then, following the design procedure, we modify the Hamiltonian function to assign a minimum at the desired equilibrium. Finally, to obtain an output feedback scheme, we inject positive damping into the system. We should underscore that, even though, adding positive damping is rather unusual in control applications, here it is naturally suggested by the design methodology. Some simulation results are presented to illustrate the properties of the controller.",

A special class of time-varying generalized canonical transformations are introduced which preserves the passivity property. Utilizing this transformation time-varying asymptotically stabilizing controllers for the nonholonomic Hamiltonian systems are derived. The proposed method is a natural generalization of passivity based control since we only employ the feedback which preserves the Hamiltonian structure of the original system.",

      "abstract": "This paper is devoted to a unified approach to trajectory tracking control of nonholonomic port-controlled Hamiltonian systems via generalized canonical transformations. The key idea is to construct an error system, which describes the dynamics of the tracking error, by a passive port-controlled Hamiltonian system. This strategy works for both holonomic and nonholonomic port-controlled Hamiltonian systems. A practical design procedure of global tracking controllers for those systems is proposed. This method is a natural extension of the conventional passivity based control and is expected to derive robustly stable control systems.",

Facing the limitation that the controlled devices can only dissipate power, the issue is to find a proper control law to satisfy the control requirements. The mechatronic systems can usually be divided into two or more subsystems that are connected by a power preserving connections. This paper proposes to choose the control inputs to lead the power towards a certain subsystems in order to satisfy the requirements by controlling the energy stored or the power dissipated in that subsystem. To this aim, the port Hamiltonian framework is used to model the mechatronic systems. A slight extension of the definition of port Hamiltonian system is proposed to allow the description of a larger set of mechatronic systems and to obtain an explicit representation of the energy flowing to a subsystem. Some of the control laws presented in literature about the control of semi-active suspensions are derived again by following the proposed approach and adding an energetic interpretation",

The B2B is a variable structure system (VSS), due to the presence of control-actuated switches; however, from a modelling and simulation, as well as a control-design, point of view, it is sensible to consider modulated transformers (MTF in the bond graph language) instead of the pairs of complementary switches. The port-Hamiltonian models of both subsystems are presented and, using a power-preserving interconnection, the Hamiltonian description of the whole system is obtained; detailed bond graphs of all subsystems and the complete system are also provided. Using passivity-based controllers computed in the Hamiltonian formalism for both subsystems, the whole model is simulated; simulations are run to test the correctness and efficiency of the Hamiltonian network modelling approach used in this work",

The modeling technique is based on the Hamiltonian system framework and on power-port interaction between subsystems. The model allows fast and precise simulations and therefore can be used for the development and the validation of control strategies by simulations and hardware in the loop experiments. The proposed model has been validated comparing the simulation results with experimental measurements",

A novel weighted balanced realization and model reduction procedure is proposed which preserves port-Hamiltonian structure as well as stability, reachability and observability of the original system. This implies that one can utilize the intrinsic physical properties such as physical energy and the corresponding dissipativity for the reduced order model. Further, the proposed method reduces the computational effort in solving partial differential equations for nonlinear balanced realization. A numerical simulation shows how the proposed method works.",

The Lscr2-gain is typically used in combination with the small-gain theorem. In particular it can be used to guarantee robust stability with respect to gain-bounded model uncertainties. This application of the Lscr2-gain is demonstrated with a biochemical fermentation process where the specific cell growth rate is unknown but contained in a parameter interval.",

Based on a finite-time stability criterion and the so-called \"energy shaping plus damping injection\" technique, the continuous finite-time stabilization problem is studied for the PCH systems, and several global stabilization results are obtained. Via Hamiltonian realization, the results obtained for the Hamiltonian systems are applied to investigate continuous finite-time stabilization of nonlinear affine systems, and several global control design results are presented. Study on several examples shows that the control design approaches developed in this paper work very well.",

This paper considers the tethered satellite in a Hamiltonian framework and determines a port-controlled Hamiltonian formulation that adequately describes the nonlinear dynamical system. Based on this model, a nonlinear controller is designed that will make the system asymptotically stable around its open-loop equilibrium. The control scheme handles the time-varying nature of the system in a suitable manner resulting in a large operational region. The performance of the closed loop system is treated using Floquet theory, investigating the closed loop properties for their dependency of the controller gain and orbit inclination.",

      "abstract": "An energy-based hybrid control framework for stabilization of multimachine power systems is proposed as a means to enhance transient stability of power systems. This approach is based on energy representation of power systems by using port-controlled Hamiltonian forms. The controllers utilize logic-based switching to enhance energy dissipation for the synchronous generators. This paper develops general energy dissipating excitation control design and stabilization results for such controllers.",

      "abstract": "Stability of a class of nonlinear systems, called port-Hamiltonian systems, in the presence of time delay in the communication between the plant and controller is studied. The delay parameter is an unknown function which varies with time and for which the upper bounds on the magnitude and variation are known. The presence of delay may destroy the port-Hamiltonian structure of the system. Because of this, stability of the time delay systems is not obvious. We thus propose a theory to test the stability of port-Hamiltonian systems with time delay. The stability problem considered here, relies on the construction of a Lyapunov-Krasovskii (LK) functional based on the Hamiltonian of the port-Hamiltonian system. Based on the LK functional, we derive some sufficient conditions for the system to be asymptotically stable in presence of uncertain delays.",

      "abstract": "In this contribution a new systematic approach is presented to achieve desired local linear error dynamics for trajectory tracking of a nonlinear plant, where passivity based control by interconnection and damping assignment (IDA-PBC) is used to stabilize the error dynamics. Especially in the tracking case the solvability of the matching PDEs may restrict a state-independent dissipation matrix for the resulting time-varying port-Hamiltonian (pH) closed loop system to be singular. This in turn may impede to prove stability with the closed loop energy as a time-varying Lyapunov function. As a consequence an extension of the approach of local linear dynamics assignment for the resulting pH system, which has been introduced in a previous paper, is proposed. A factorization of the state- and time-dependent design matrix can ensure complete damping of the closed loop system, while the principal part of the matching PDEs remains state-independent to simplify the solvability conditions and the solution itself. The application of the approach is presented with the magnetic levitation experiment, including the estimation and optimization of the domain of attraction.",

We propose a novel construction which exploits the notion of algebraic solution of the so-called matching equation. The latter notion is instrumental in constructing an energy function defined on an extended state-space without involving the solution of any partial differential equation. This results, differently from the classical solution, in a dynamic state feedback that stabilizes a desired equilibrium point. Finally we show that, in the linear time-invariant case and under standard assumptions, the proposed methodology provides the standard passivity-based controller.",

The proposed controller is obtained combining a redesign of the recently reported exponentially stable immersion and invariance velocity observer and a new state-feedback passivity-based controller, which assigns to the closed-loop a port-Hamiltonian structure with a desired energy function. The result is applicable to a large class of mechanical systems including those with unbounded inertia matrix and possible presence of friction forces. Unlike previous results that rely on the presence-exact knowledge and pervasiveness-of these forces, our design treats them as disturbances, which are suitably compensated.",

Our main contribution is the identification of a class of systems for which a globally stable PI can be designed knowing only the systems input matrix and measuring only the actuated coordinates. The construction of the PI is done invoking passivity theory. The difficulties encountered in the design of adaptive PI controllers with the existing theoretical tools are also discussed. As an illustration of the theory, we consider port-Hamiltonian systems and a class of thermal processes.",

      "abstract": "This paper is devoted to the design of a port Hamiltonian controller for different scenarios of brachiation movement by a two-link bio-inspired robot called brachiating robot. A unified technique for trajectory tracking control problem of nonholonomic (drift-less) port Hamiltonian systems was introduced in the past, which exploits a generalized canonical transformation to form an error system in order to convert the trajectory tracking problem into a stabilization one. Although the method is novel and promising, only fully actuated systems are considered and success of the approach relies on the possibility of solving a set of partial differential equations (PDEs). Considering the fact that the brachiating robot is an underactuated system which suffers from lack of control input, the control problem is demanding and solving the PDEs remains the main stumbling block for an applicability of the aforementioned technique to our problem. By exploiting insight to the intrinsic properties of the underactuated system and using some math tricks, we solve the PDEs explicitly and shape the kinetic and potential energy of the brachiating robot within the port Hamiltonian framework so that the brachiating maneuver is performed efficiently and without any redundant backward movements. Furthermore, the trajectory tracking control is proved thanks to the passivity property of the system. This paper opens up the way to deal with underactuated control problems in a different and broader framework and the method demonstrates promising outcomes in the analysis and simulation as will be showed here.",

It satisfies <inline-formula> <tex-math notation=\"LaTeX\">$g^{2}=-1$ </tex-math></inline-formula> but is different from the imaginary operator. With the help of the port-Hamiltonian systems theory, it is proved that the ghost of a system behaves exactly in the opposite way as the original system. This brings the ghost of a system into reality and paves the way to reveal the physical meaning of some imaginary concepts. Two applications are given as an example. One is to reveal the physical meaning of reactive power in electrical systems: it is the (real) power of the ghost system, which leads to a significantly simplified instantaneous power theory called the ghost power theory. The other is to define the reactive power for mechanical systems to complete the electrical–mechanical analogy. As a matter of fact, the resulting instantaneous power theory is generic and applicable to any dynamic system that can be described by the port-Hamiltonian model.",

      "abstract": "Power swings may cause power system instability; therefore, hybrid energy storage systems (HESSs) are necessary to smooth the output of wind farms. Superconducting magnetic energy storage (SMES) systems have a high power density, whereas battery energy storage systems (BESSs) provide a high energy density. The significant contribution of this paper is the proposal of hierarchical control strategies for an HESS composed of an SMES system and a BESS. Mathematical models and port-controlled Hamiltonian (PCH) models of the HESS are established. At the device level, a novel HESS control strategy based on the PCH models is proposed to improve its output performance. At the system level, a multilevel power allocation method based on empirical mode decomposition, Fuzzy control and advanced control is proposed to achieve an efficient grid connection for a wind farm; the grid connection considers the real-time and future state of charge of the SMES system and BESS. The effectiveness of the proposed strategies are verified through simulation studies.",

      "abstract": "In this paper, we propose a hybrid coordinated control method based on port-controlled Hamiltonian and backstepping to improve the position tracking performance for two degree of freedom SCARA robot. The port-controlled Hamiltonian (PCH) control is designated to ensure the stability of the system, and the backstepping control targets to improve the response speed of the system. Exponential function is used as a coordination function to achieve the coordinated control strategy to adapt to the position tracking control of 2-DOF SCARA robot. This hybrid coordination control system not only realizes a quick tracking control, but also improves the steady-state performance of the output signal. The simulation results show that when the external interference exists in the mechanical system of a 2-DOF SCARA robot, the hybrid tracking control system takes on the advantages of both methods, which shows good dynamic performance, good steady-state performance, and strong resistance to external interference.",

      "abstract": "This paper presents a novel nonlinear control strategy for a superconducting magnetic energy storage (SMES) system during network unbalance. Grid voltage unbalances tend to substantially degrade the operation of a SMES system; conventional control methods cannot completely address this issue. In this paper, three selectable control targets for the SMES are identified according to the working principle of the SMES under an unbalanced voltage condition to reduce the impacts of second harmonics in output power, output reactive power, and grid-side current. Next, the port-controlled Hamiltonian models of the SMES are established, and the positive- and negative-sequence interconnection and damping assignment passivity-based control (PBC) strategies are proposed accordingly. Simulation results show that the PBC has stronger robustness in both steady and dynamic states compared with the conventional proportional integral method, which effectively suppresses the oscillations caused by the unbalanced voltage.",

      "abstract": "A port-controlled Hamiltonian (PCH) control approach is presented to solve the position tracking problem of gantry robot based on induction motor (IM) drives. First, a robot model is established. Second, a PCH controller is designed to realize accurate position tracking of a gantry robot. For IM drives, it is convenient to choose a direct torque control strategy based on the sliding mode control, which overcomes the higher ripples of torque and flux. Third, a voltage reconstruction technique is introduced to calculate the stator voltage of the IM, which replaces the stator voltage measurement of the IM. Finally, the load torque observer is developed to estimate an unknown load torque. The asymptotic stability of the robot system is proved by the Lyapunov stability theory. Simulation results indicate that the system has excellent position tracking performances and load disturbance attenuation ability.",

      "abstract": "In this paper, a composite control scheme is presented to asymptotically stabilize a class of port-controlled Hamiltonian systems under nonvanishing disturbances. First, based on the damping injection method and the nonlinear disturbance observer (NDOB) technique, the robust composite control strategy is designed. The NDOB, as an effective observation tool, is developed to estimate the disturbances, and furthermore, the disturbances can be feedforward compensated using the estimates of disturbances. Then, for the augmented system, an asymptotic stability theorem is proposed via an input-to-state stability technique and Lyapunov stability theorems. The proposed control approach exhibits not only good robustness and disturbance rejection performances but also the property of nominal performance recovery. Finally, a simulation example on a circuit system is given to show the feasibility and advantage of the composite control method.",

      "abstract": "This paper is mainly focusing on the problem of speed tracking control for permanent magnet synchronous motor (PMSM) drive system subject to matched and mismatched disturbance. This is achieved by a novel Port-Controlled Hamiltonian control method with nonlinear disturbance observer. Different from the traditional speed-current cascade control for PMSM, the speed-current single loop controller is designed. Firstly, the Port-Controlled Hamiltonian model of PMSM is established, then the Hamiltonian speed controller is designed by using interconnection assignment and damping assignment method. However, the standard Hamiltonian controller cannot achieve the satisfying behavior in the presence of the parameter variations and external disturbance, thus a nonlinear disturbance observer is designed to estimate the lump disturbance of the system, which is used to the feed-forward compensation control. Finally, simulation and experiment on the speed control system of PMSM are implemented. The results show that the proposed method has fast speed control performance and strong robustness for the different disturbance.",

      "abstract": "With the integration of wind energy, the widely used doubly fed induction generator wind turbines (DFIG-WT) could induce Power System forced oscillations (FOs), which threaten the safety of power grid. In this paper, an accurate FOs location method is proposed to pinpoint sources of FOs to the specific components inside a DFIG-WT and a participation assessment method is proposed to evaluate the role of DFIG-WTs in the FOs event. Firstly, the energy structure of the DFIG-WT is constructed and the correspondence between the physical components and energy structure of the DFIG-WT is established. Thus, the sources of FOs can be located by the energy flow among the converter, wind turbine and induction generator. Furthermore, the port-controlled Hamiltonian (PCH) method is used to analyze the influence of external disturbances to the potential energy of DFIG-WT, based on which the participation factor of the DFIG-WT in FOs event can be defined. The simulation results demonstrate that the proposed method is able to locate the oscillation sources accurately and reveal the participation of the DFIG-WT in FOs events effectively.",

      "abstract": "This paper investigates the problem of the level control for two tank liquid level system(TTLLS) with parametric uncertainties and lumped disturbances. It is achieved by a novel adaptive disturbance attenuation control method based on the Port-Controlled Hamiltonian (PCH) model. Firstly, the model of TTLLS is established according to the mass balance principle and the PCH model is achieved. Based on the PCH model, the PCH controller of TTLLS is designed and the stability of the closed-loop system is ensured. To reduce the impact of disturbances and unmeasurable parameters, adaptive $L_{2}$ disturbance attenuation technology is integrated. To achieve the robustness and simplify the calculation, the parameter estimation vector is designed by splitting complex mathematical expressions. Utilizing the properties of the PCH method and merits of the adaptive disturbance attenuation technology, the integrated controller achieves good performance. Moreover, simulation and experimental results are given to show the effectiveness and strong robustness of the proposed control algorithm.",

      "abstract": "With the large-scale development of offshore wind power and the rapid development of smart grid, more and more attention has been paid to the stable operation of wind turbines under various conditions. In the actual operation process of wind turbines, there are inevitably many kinds of uncertain time delays, and also external or parameter disturbances, which affect the stable operation of wind turbines and make the system deviate from the original stable state. Based on Hamiltonian energy theory, the disturbance rejection of doubly fed wind turbines with multiple time delays is studied in this paper. Firstly, the doubly fed wind turbine is Hamiltonian realized to obtain its port controlled Hamiltonian with dissipation(PCH-D) model. Then, aiming at the PCH-D model, a multiple time delays controller is designed based on Casimir function, which can make wind turbines run stably under multiple time delays. Furthermore, based on the passive control theory, L2 gain disturbance rejection control technology is introduced to eliminate the steady-state error caused by external disturbance and improve the stability of wind turbines. Finally, the simulation results show that the proposed controller can effectively solve the multiple time delays and disturbance problems in the system, and improve the stability and anti-interference of wind turbines.",

During the movement of the secondary coil of the movable multi-load ICPT system, due to the change of mutual inductance and the randomness of the multi-load, it will cause the transmission power and efficiency to oscillate and generate harmonics. Firstly, in view of the above problems, this paper analyzes the ICPT system under movable multiple loads. The DQ transformation method was used to establish the large-signal mathematical model of the system, and PCHD mathematical model in the DQ domain was established to decouple the active and reactive power. Secondly, the passivity-based controller (PBC) is designed by using the principle of interconnection and damping assignment passivity-based control (IDA-PBC). After that, the second method of Lyapunov function is used for stability analysis, and further verifies the asymptotic stability of the closed-loop system. Finally, the proposed method was verified by MATLAB/Simulink simulation. The simulation results show that the passivity-based controller has stronger robustness in both steady and movable states compared with the PI controller, which effectively suppresses the oscillation and total harmonic distortion caused by the change of mutual inductances and the randomness of the loads.",

      "abstract": "In this article we present the implementation in Modelica language of a library with the fundamental components for modeling a wide variety of multiphysics systems. Modelica is an object-oriented modeling language, which allows to make a simple, systematic and elegant design of the library. The mechanisms of inheritance and composition of Modelica facilitate the modeling and reuse of components in different domains of Physics. To model the behavior of each component in a systematic framework we have used the theory of port-Hamiltonian systems, formulated mainly by means of differential geometry. The port-Hamiltonian approach allows a methodical definition of complex systems by connecting simple systems that exchange energy through connection ports. To graphically represent the components of a system and their connections, we have employed slightly modified bond graphs symbols for easier reading. The general and systematic applicability of the library is illustrated via two examples framed in different domains of Physics: the mechanical Sun-Earth-Moon system where we perform an analysis of errors that justifies the employed system of units, and the electrical nonlinear Chua circuit, modeled by composition of port-Hamiltonian subsystems. Both derived models have been built and simulated based on the more general models of mechanical and electrical systems, which are also part of the library developed with the port-Hamiltonian approach.",

      "abstract": "This paper presents a passivity-based control method for a small hydro-power system that consists of a permanent magnet synchronous generator (PSMG) connected to the grid through a back-to-back converter. Nonlinear models of the hydraulic, mechanical, and electrical parts of the small hydro-power system are considered. Two approaches in the realm of passivity-based control are implemented, namely, standard passivity-based control and PI-passive. These controls consider the intrinsic characteristics of the model, which has a port-Hamiltonian (pH) structure with a small hydro-power system in open-loop. The purpose is to design a control law with passive output which ensures asymptotic stability for closed-loop operation in the sense of Lyapunov’s theory. The paper is practically oriented, and hence, the proposed controllers are tested and compared with a conventional approach, in a 13.2 kV distribution feeder. The proposed controllers have been assessed and compared with a classical PI controller considering steady state and transient behaviors in small hydro-power plants (SHPs). Simulation results show that the proposed methodology guarantees stability and offers better dynamical performance.",

      "abstract": "We present a port-Hamiltonian system (PHS) model based on the interconnection between basic hydraulic elements equivalent to electrical components such as capacitors, inductors, and resistors to represent the dynamics of a water micro-channel experimental plant. We compare the fluid-structured interconnected PHS model with the data obtained from a micro-channel experimental plant. We then implement a controller using the total hydraulic-mechanical energy as a local Lyapunov function. Finally, we apply an integral action controller (IAC) to correct for modeling errors and load disturbances. The IAC is easy to design given the proposed interconnected model.",

      "abstract": "In this paper we present a robust trajectory tracking control for a fully actuated marine surface vehicle. The tracking controller is obtained using a port-Hamiltonian model of the marine craft and includes an integral action to compensate for constant disturbances. The proposed approach adds damping into both the position and integrator coordinates, leading to input-to-state stability with respect to time-varying disturbances. We exemplify this controller with a simulation for an unmanned surface vehicle subjected to constant and time-varying wind disturbances. The tracking controller rejects the disturbances achieving global exponential stability for constant disturbances and input state stability for time-varying disturbances.",

      "abstract": "In this paper, we present the physical foundations and the development of the thermodynamic part of a Modelica library with the fundamental components for modeling thermofluid systems. We have chosen Modelica because it is an object-oriented modeling language that allows an elegant design of the library, with a top-down conception that starts from very general components where we model the thermodynamic properties common to all simple substances and descend by inheritance to model the properties of each particular substance. To model the behavior of each component, we have used: classical thermodynamics to define the equilibrium states, the local equilibrium hypothesis of Classical Irreversible Thermodynamics to model the changes of state, and the port-Hamiltonian approach to obtain the equations of the system dynamics. With this formulation, we implement the thermodynamic behavior of ideal gases (including monatomic gases as a particular case), the 2073 substances defined for the CEA (Chemical Equilibrium with Applications) NASA Glenn computer program, the IAPWS Formulation 1995 for the Thermodynamic Properties of Water Substance for General and Scientific Use, and the Syltherm 800 HTF (Heat Transfer Fluid). We also define graphical symbols for each library component that facilitate modeling complex systems with simple drag-and-drop manipulations, component connection, and parameter selection. These symbols are a slightly modified version of those used in bond graphs to facilitate their reading and the representation of the structure of complex systems. We also show the modeling, simulation, and comparison for accuracy, performance, and scalability of some thermodynamic systems implemented with the Modelica Standard Library (MSL) and the proposed library.",

      "abstract": "The conflict between dynamic rapidity and steady-state accuracy is a crucial factor hindering the performance improvement of motor control system. To overcome the issue, this article proposes an optimized cooperative control combining feedback linearization (FBL) and error port-controlled Hamiltonian (EPCH) for permanent magnet synchronous motor (PMSM). First, FBL and EPCH are separately designed to obtain good dynamic and steady-state performances. Then, considering the individual advantages of FBL and EPCH, a cooperative strategy based on the real-time position error is applied to realize the smooth switching between the two methods, so that each method is utilized efficiently within the corresponding operating range. In addition, the particle swarm optimization (PSO) algorithm is introduced to properly select the controller parameters. Thus, an optimized cooperative control method, which takes into account both fast dynamic response and high steady-state precision, is developed for PMSM drives. The experimental results are finally given to illustrate the effectiveness and superiority of the proposed method.",

      "abstract": "The control of a flexible beam using ionic polymer metal composites (IPMCs) is investigated in this paper. The mechanical flexible dynamics are modelled as a Timoshenko beam. The electric dynamics of the IPMCs are considered in the model. The port-Hamiltonian framework is used to propose an interconnected control model of the mechanical flexible beam and IPMC actuator. Furthermore, a passive and Hamiltonian structure-preserving linear quadratic Gaussian (LQG) controller is used to achieve the desired configuration of the system, and the asymptotic stability of the closed-loop system is shown using damping injection. An experimental setup is built using a flexible beam actuated by two IPMC patches to validate the proposed model and show the performance of the proposed control law.",

      "abstract": "This article proposes a distributed secondary control scheme that drives a dc microgrid to an equilibrium point where the generators share optimal currents, and their voltages have a weighted average of nominal value. The scheme does not rely on the electric system topology nor its specifications; it guarantees plug-and-play design and functionality of the generators. First, the incremental model of the microgrid system with constant impedance, current, and power devices is shown to admit a port-Hamiltonian (pH) representation, and its passive output is determined. The economic dispatch problem is then solved by the Lagrange multipliers method; the Karush-Kuhn-Tucker conditions and weighted-average formation of voltages are then formulated as the control objectives. We propose a control scheme that is based on the Control by Interconnection design philosophy, where the consensus-based controller is viewed as a virtual pH system to be interconnected with the physical one. We prove the regional asymptotic stability of the closed-loop system using Lyapunov and LaSalle theorems. Equilibrium analysis is also conducted based on the concepts of graph theory and economic dispatch. Finally, the effectiveness of the presented scheme for different case studies is validated with a test microgrid system, simulated in both MATLAB/Simulink and OPAL-RT environments.",

      "abstract": "This paper is concerned with the anti-saturation control problem of a permanent magnet synchronous wind power system. By virtue of adaptive sliding mode control method and port-controlled Hamiltonian (PCH) control method, a new coordination controller is designed, which removes the input saturation effects and compensates the uncertainties of system model parameters. The controller takes the exponential function with parameters as the coordination function. By adjusting the parameters of coordination function, the designed coordination controller can respond to input saturation more quickly and improve the system’s dynamic performance. The effectiveness of the proposed strategy is demonstrated through simulations. The comparison results with the traditional control approach are also presented. It is shown that the proposed strategy can realize the speed tracking control of the generator and improve the maximum wind energy capture of wind turbine, so as to further improve the utilization efficiency of wind energy.",

      "abstract": "In this paper, a grid-forming (GFM) control is developed based on the nonlinear Port-Hamiltonian (PH) system theory to systematically achieve tracking control and Lyapunov-based stability by considering the power flow dynamic, voltage and current dynamics of voltage source converters (VSCs) system. The proposed controller is robust to both matched constant and periodic disturbances (e.g., grid voltage/frequency fluctuation, load change, voltage harmonics) and nonlinearities due to structural model uncertainties (e.g., output/line impedance variation, coupling effect). Compared to the conventional linear proportional resonant (PR)-based controller, the proposed PH-based nonlinear controller has uniform transient dynamic performance among different operating conditions in large disturbance rejection scenarios, resulted from the ensured closed-loop (semi)globally stable and uniform error dynamics with design facilitated configurable interconnection and damping matrices fixed by initial settings. Experimental results are presented to demonstrate the effectiveness of the proposed control framework in various working conditions.",

      "abstract": "The azimuth axis drive and control of large telescopes based on Segmented Arc Permanent Magnet Synchronous Motor (SAPMSM) is a current research hotspot, and issues such as unknown parameters and external interference are important factors affecting its tracking accuracy. This paper proposes a SAPMSM perturbation suppression strategy for large telescopes based on port-controlled Hamiltonian (PCH) theory. In this study, the Hamiltonian mathematical model of SAPMSM is established and the current controller of the SAPMSM is designed to reduce harmonics by configuring the required interconnection and damping matrix. In order to further improve the accuracy and anti-disturbance performance of speed feedback, a Generalized Proportional Integral Observer (GPIO) is selected for total disturbance observation, estimation and compensation. The experimental results indicated that the algorithm proposed in this paper has lower harmonic content in the phase current of the SAPMSM, which can ensure good position tracking ability and anti-interference performance of large telescopes.",

      "abstract": "This paper presents a unified adaptive passivity-based control strategy using incremental modeling to regulate the angular speed of a DC series motor driven by DC-DC converters operating in both buck and boost configurations. The proposed approach leverages an incremental port-Hamiltonian framework to design control laws that ensure the global asymptotic stability of the closed-loop system. To address the challenge posed by unknown load torques, a nonlinear disturbance observer is incorporated, allowing for the real-time estimation required for an accurate computation of equilibrium points and reference tracking. These theoretical developments are validated through experimental implementation and compared against an inverse optimal control (IOC) strategy. The results show that the proposed IDA-PBC significantly outperforms the IOC in terms of transient response, tracking accuracy, and disturbance rejection. In the buck configuration, the IDA-PBC reduces the rise time by up to 50.24% and completely eliminates the overshoot. Similarly, in the boost configuration, the rise time is improved by 20.63%, with enhanced stability and lower phase lag under sinusoidal tracking. These findings confirm the robustness and effectiveness of the proposed control strategy for real-time applications in electromechanical systems.",

      "abstract": "This paper proposes a passivity-based model predictive control (PB-MPC) strategy for a grid-connected photovoltaic system (PVS). The approach combines port-Hamiltonian modeling (pH) with the predictive and constraint-handling capabilities of MPC, preserving the system’s energy structure while enabling explicit constraint management. A discrete-time incremental pH formulation is derived, from which system passivity is theoretically established. The control problem is solved using a single-iteration Newton–Raphson scheme per sampling step, where control input constraints are enforced through projection onto the admissible control set, enabling real-time implementation. Simulation results demonstrate superior performance compared with conventional MPC and Porportional-Integral (PI) controllers, while additional analyzes confirm robustness, computational efficiency, and passivity preservation of the proposed controller. Real-time hardware-in-the-loop (HIL) validation using the OPAL-RT OP4512 platform further demonstrates improved dynamic response and reduced settling time.",

      "abstract": "Modular multilevel converter (MMC) is widely applied to high power renewable energy generation, due to the randomness of the renewable energy fluctuation, the system parameter perturbation and the nonlinear characteristic of MMC. The traditional vector control method can suppress the MMC circulating current, but it is hard to make sure the system strongly global stability and robust performance. To solve this problem, a novel passivity-based circulating current suppressing method based on port-controlled Hamiltonian with dissipation (PCHD) model is proposed. Based on the MMC global energy function of the PCHD model, the passivity-based controller is designed to modify the energy of closed-loop system by shaping storage function, so that the system energy could obtain the minimum value at the desired equilibrium point. The global asymptotic stability of the system is realized. The simulation results of MATLAB/Simulink shows that the proposed passivity-based circulating current suppressing method of MMC has the advantages of simplicity and good transient performance, and the system is globally stable and strongly robust.",

      "abstract": "High-performance control of induction motors has always been an important research direction in field of nonlinear control. The passivity-based control (PBC) method has brought a new solver to the globally stable controller design problem of nonlinear induction motor. The aim of this paper is to develop a control algorithm to realize asymptotically tracking of flux and speed under unknown time-varying load torque, and repress the tracking error caused by the stator and rotor resistance changes. To achieve this, a port-controlled Hamiltonian with dissipation (PCHD) model of induction motor is built, and a nonlinear feedback PBC method, combined with sliding mode control, is proposed. From the energy point of view, the inductor motor control system is analyzed and the “workless forces” is determined, which does not have any effect on the energy balance equation of the closed control system. This leads to a simple control structure with nonexistence of singularity and enhances the robustness of the control system. The reasonability and validity of the proposed method is testified by the experimental results based on dSPACE.",

      "abstract": "This paper presents Layer 1 of ARISE (Autonomous Reconfigurable Infrastructure for Swarm-based Exploration): a separation damping layer that rapidly suppresses post-release tip-off and drift in a carrier-deputy spacecraft swarm. We model each vehicle as a mechanical port-Hamiltonian (pH) system evolving on the Special Euclidean group $S E(3)$ and shape a convex storage function about the desired relative pose. By injecting collocated damping through the body-wrench port, the closed loop is made strictly passive, so the shaped Hamiltonian serves as a Lyapunov storage that decreases monotonically. We provide compact passivity guarantees in continuous time and in sampled implementation, including a bounded-delay extension using a passivity observer/controller (PO/PC). To realize the commanded wrench under actuator limits, we use a constrained allocator posed as a bounded nonnegative least-squares (BNLS) problem and give a condition under which damping dominates allocation and saturation errors. In a representative near-Earth-object flyby separation case study (Apophis-2029 reference), the layer drives both carrier and deputies to low-rate, low-drift conditions within minutes and remains robust to thrust dispersion, inertia variation, saturation, and fixed command latency. These results show that a minimal, passivity-based realization can reliably drain separation transients and hand off the swarm to subsequent formation-setting and pointing phases with clear stability margins.",

Both the change of coordinates and the dynamic extension add extra degrees of freedom that facilitate the solution of the matching equation associated with interconnection and damping assignment passivity-based control designs (IDA-PBC). The stability of the controlled system is proved using the closed loop Hamiltonian as a Lyapunov candidate function. The performance of the proposed controller is shown in simulation.",

The control design is based on Port-Hamiltonian theory. The target dynamics (desired dynamic response) is shaped with particular attention to the target mass matrix so that the influence of the unactuated dynamics on the controlled system is suppressed. This results in achievable dynamics independent of uncontrolled states. Throughout the design, insight of the physical phenomena involved is used to propose the desired target dynamics. The performance of the design is demonstrated through simulation with a high-fidelity model.",

In particular, for the studied class of systems we show the Kalman-Bucy filter itself is a port-Hamiltonian systems and by invoking the second law of thermodynamics, we can characterize the external power supply needed to generate an optimal state estimate. We also show how the required external power supply can be decreased by allowing the filter to perturb the measured system to a larger extent. Hence, it is possible to decrease the so-called back action of the filter by spending more energy. We illustrate our results using passive electric circuits.",

      "abstract": "In this work a new and fast network-wide framework is addressed for modeling and tracking the dynamic behavior of transmission lines in Power Networks (PN). A sparse-based mathematical formulation for Transmission Line Dynamic Behavior Tracking (TLDBT) is formed by incorporating a PN Port-Hamiltonian model. Among the TLDBT a new set of intermediate parameters called the line dynamic index coefficients (LDIC) are defined based on the wave propagation analysis of current waves in transmission lines. It is shown how these coefficients can reflect the dynamic behavior of the transmission lines. The online monitoring of variations in these index coefficients is interpreted as an alternative approach for TLDBT in power grids. Finally, exploiting the inherent sparsity in the PN structure this TLDBT problem is reformulated as a Structured Sparse Recovery Problem (SSRP) and the TLDBT-SSRP is solved for LDICs. The simulation results indicate that the proposed framework can be considered as an alternative approach to address the new challenges in the future generation of smart power grids modeling, monitoring and congestion-management strategies.",

An interconnection and damping assignment passivity-based control (IDA-PBC) approach is employed to design the closed-loop controller taking advantage of the port-Hamiltonian structure of the converter under average modeling. An adaptive online method to estimate the CPL consumption is made by guaranteeing asymptotic stability in Lyapunov’s sense for closed-loop operation. Numerical validation between a nonlinear controller based on a sliding theory and the proposed IDA-PBC approach demonstrates the effectiveness and robustness of the passivity-based methods for regulating voltage profiles in boost converters, including large-scale variations in the CPL. All the numerical validations are conducted in MATLAB/Simulink software.",

Based on this model we design a controller using the total hydraulic-mechanical energy as a local Lyapunov function. The objective is to control the level of the micro-channel in some arbitrary point inside the channel.",

Subsequently, an innovative harmonic suppression method of grid-connected current for voltage-controlled inverter has been presented. The grid-connected inverter model is transposed to the port-controlled Hamiltonian model, and the grid-connected controller is constructed on the energy-shaping control theory. This approach significantly simplifies the structure of the grid-connected controller and manages parameter quantity. Based on these findings, the effectiveness of the proposed harmonic suppression method in injected grid current is verified under various operating conditions via an experimental platform for the inverter, which employs the Danfoss inverter and RT Box controller.",

The observer is applied to the boost converter and the observation of the inductor current tracks the actual value well.",

      "abstract": "In this paper we present a passivity-based control (PBC) design for stabilisation of a DC-DC buck converter subject to nonlinear loads and matched and unmatched disturbances. We propose a stabilising dynamic controller that also implements integral action in the closed-loop system to reject constant disturbances. We show that the desired equilibrium in closed loop is exponentially stable and that it is input-to-state-stable with respect to matched and unmatched disturbances. The controller is designed within the framework of port-Hamiltonian theory, which allows us to ensure stability and robust closed-loop properties. We also characterise, in terms of the Volt-Ampere functions, the class of nonlinear loads that the controller can handle. The resulting controller is a classical interconnection and damping assignment PBC with integral action. An advantage of our design process is that we solve the so-called matching equation by construction; thus, we avoid the need of solving partial differential equations (PDEs). The performance of the control system is assessed via numerical simulations of the closed loop under several disturbance scenarios.",

The Port-controlled Hamiltonian system with dissipation (PCHD) model of permanent magnet synchronous motor with voltage disturbance is established by introduction of the state error and the integral action. The Lyapunov function is constructed to analyze the stability of system under the condition of constant and time-varying perturbations. This control strategy can obtain the control law of the d, q axis and integral action, and can keep an exponential convergence of the closed loop system. Experimental simulation results show the proposed control strategy can effectively suppress the constant and time-varying disturbances, eliminate the steady-state error, and improve the robustness of system.",

      "abstract": "In this paper, a new approach is successfully addressed to design the optimal controller of the port controlled Hamilton (PCH) system. The expected energy of the PCH system is shaped into the value function satisfying the Hamilton-Jacobi-Bellman (HJB) equation, where the method of interconnection and damping assignment is applied, and the expected energy is derived by exploiting the matrix decomposition approach. It is shown that the proposed method has many potential advantages for both theory and application of the optimal control of the PCH systems such as, instead of solving partial differential equations, the matching conditions in the optimal control become a set of algebraic equations. In practice, the discussed method is used to the optimal control of the induction motor for electric vehicle, and the simulation results are provided to validate the concepts.",

      "abstract": "A novel four quadrant operation control strategy of permanent magnet synchronous motor (PMSM) drive systems is proposed. In order to regulate precisely output direct current (DC) bus voltage and achieve the control of unity power factor, the exponential functional-based sliding mode reaching law (ESMRL), which adapts to the variations of the grid-side inverter and sliding mode surfaces, is developed. The mathematical model of PMSM based on port-controlled Hamiltonian (PCH) is established according to the energy-balancing point of view. On the basis of energy optimization and operation in four-quadrant, the PCH controller using energy-shaping and passivity-based control is applied in motor-side inverter. The controllers proposed ensure that the motor can run in four-quadrant, energy is bidirectional flow, the DC bus voltage is controllable, the power factor is near one and energy consumption is smaller. The simulation results authenticate the validity of the presented control algorithms.",

First, an exponential adaptive observer with Hamiltonian structure for uncertain generalized PHS is given based on the idea of augment plus feedback. Compared with the conventional observer design method, the proposed observer can maintain the structure of original system and simultaneously guarantees the completeness of the state's physical significance. Then, based on designed observer, we proposed an adaptive tracking control strategy by using the structure properties of the PHS and CM. Moreover, an analysis is provided of the relevant decay rate and how parameters affect tracking speed of system. Ultimately, simulation results demonstrated the effectiveness of proposed method.",

      "abstract": "Formation control of multiple unmanned surface vessels faces complex and changing environments and mission requirements, and the realization of efficient and complex formation control and the reduction of energy consumption have become key issues that need to be urgently addressed. In order to enhance system optimization, a state error port control Hamiltonian approach is employed to develop a Fourier-based controller for multiple unmanned surface vessels. It uses truncated Fourier series approximation curves and their finite coefficients to describe the shape of the curves in a state-error-port Hamiltonian framework. It automatically assigns multiple unmanned surface vessels to each of the formation control systems. The numerical and experimental results indicate that this approach not only simplifies the formation control process but also significantly reduces energy consumption. The algorithm has good tracking performance for closed boundaries of complex shapes, providing a novel and effective solution for complex formation tasks.",

The model is used to illustrate, sound transmission through the middle ear of a healthy subject. Parameters for validating the developed model were obtained from existing literature. The results indicate a peak at 1 kHz, confirming the behaviour of the middle ear as a resonant system tuned to the frequency between 700 and 1200 kHz. The results were found to be comparable to clinical and audiological data in existing literature. Future improvements to the presented model would include the rotational motion of the Stapes in the middle ear.",

      "abstract": "In this paper, we propose an energy-based approach to feedback control problem for a hopping robot on an elastic ground. In order that the system behaves in a periodic hopping motion, we make an attempt to keep the system's total energy (Hamiltonian) to a certain specified value. Since our target is inherently a hybrid system, which has discontinuous, and discrete event dynamics, we suggest a suitable impact model and describe it as a hybrid version of port-controlled Hamiltonian system. Then a passivity based control called IDA (interconnection and damping assignment) is applied to this problem, which results in a good performance in the ideal situation. Moreover, we introduce a servo-like integrator into this controller to reject disturbances due to modeling uncertainty. Efficiency of the proposed method is validated both in simulations and experiments using our newly developed hopping robot system.",

This model is one example of systems that have complex energy variables. For such a model, a unified modeling method is introduced with multivariable representation. First, a Stokes-Dirac structure is related to the calculus of variations by using a jet bundle formalism. Next, the flexible beams model is represented as the port Hamiltonian system. Finally, the model is compared to a conventional model and two reduced models",

This paper proposes a DHR for multi-machine multi-load power systems based on a novel DHR structure for nonlinear differential algebraic systems, with which we derive a sufficient condition for the existence and construction of DHRs with constant structure matrices. An example shows that the proposed DHR can facilitate the excitation controller design of power systems.",

      "abstract": "In this brief note a new strict Lyapunov function for mechanical systems controlled by the well-known Passivity-based Control technique of Interconnection and Damping Assignment is proposed. The general, total energy-shaping, formulation of the control technique is considered, which yields a port-Hamiltonian closed-loop system with non-fixed symplectic structure. To construct the proposed Lyapunov function a new systematic mathematical machinery is introduced. The resulting Lyapunov function contains, as particular cases, previous functions obtained for robot manipulators controlled by potential energy-shaping (plus damping injection) schemes. An additional contribution of our work is that, in contrast with most of the existing literature on this topic that is restricted to robot manipulators with only revolute joints, our analysis is applicable to robots with both revolute and prismatic joints. As an illustration example, practical bounds for a two-link direct drive robot manipulator are computed.",

Special interest has been shown to processes at constant temperature and pressure. The Port-Hamiltonian model of network of chemical reactions both in the concentration space and the reaction space followed by the Interconnection and Damping Assignment-Passivity Based Control (IDA-PBC) for open chemical systems is formulated here. Futhermore, application to bioprocess in batch and continuous modes has opened the energetic way of looking in to the modeling and control of such reactions. The technique is applied to model and simulate the control of enzymatic hydrolisis of cellulose in a continuous reactor. Special care has been taken to not look loosely on the physical coherence of a system, hence this paper can be an inspiring alternative to pseudo formulations and artificial control in the domain of biochemical engineering.",

      "abstract": "The interest for the vocal fold modeling and in numerical simulations of voice production has arised due to the need to better understand the basic physics of voiced speech and to provide diagnosis and treatment for people with voice disorders. Different models have been proposed and used for both clinical and scientific research studies. Lumped-element models of the vocal fold viscoelastic structure coupled with various aerodynamic and acoustical models have proved to be one of the most useful approaches. On the other hand, the port-Hamiltonian systems (PHS) approach provides a powerful tool for analysis, modeling and control of complex dynamical systems. The approach is based on an energy point of view of systems and has been used in several applications. In this paper, we apply the port-Hamiltonian systems approach to model the voice production system. In particular, we obtain a switching PHS, for a body-cover model of the vocal folds. The resulting model explicitly shows the energy storage, energy dissipation and the interconnection underlying in the system. Additionally, different discretization of the obtained model are discussed.",

      "abstract": "This paper addresses the problem of voltage output regulation in DC Buck converters from the passivity-based control (PBC) point of view. The PBC takes advantage of the natural port-Hamiltonian representation of dynamic equations of the buck converter, to design a feedback controller with proportionalintegral gains, that allows to guarantee stability conditions in the sense of Lyapunov for closed-loop operation. The design of the controller is based on the incremental dynamic model of the buck converter. The PBC approach considers unknown resistive loads in the controller design without degrading the dynamic performance of the controller. In addition, the proposed approach allows to design a controller regardless the buck parameters (capacitance and inductance) which makes it robust to parametric uncertainties. Sliding planes and classical PI control methods are used for comparing the proposed PBC method. All simulations have been performed in MATLAB software by using SymPowerSystems library.",

      "abstract": "This paper deals with the output voltage regulation problem in a direct current (DC) microgrid interfaced through an interleaved boost converter while the power transference is indirectly controlled. The interleaved boost converter is modeled using the averaging modeling theory to obtain a continuous bilinear dynamical model using a port-Hamiltonian (pH) representation. The pH representation is used to design an efficient controller with proportional and integral action that preserves the passive structure of the model during the closed-loop operation via passivity-based control theory (i.e., a PI-PBC design). At the same time, stability properties in the sense of Lyapunov are ensured. The proposed PI-PBC controller is compared against a nonlinear one based on the exact feedback control (EFC) theory. Numerical simulations in the PLECs software for MATLAB/Simulink reveal the effectiveness of the proposed EFL control in comparison with the EFC design when voltage and power variations are simultaneously tested.",

      "abstract": "Using a proportional-integral passivity-based control (PI-PBC) framework, this paper addresses the modeling and nonlinear control of a DC-DC boost converter operating in continuous conduction mode (CCM). The converter is first described through an averaged state-space model, which is reformulated as a port-Hamiltonian (pH) structure to facilitate energy-based control design. A PI-PBC law is proposed using component-wise error signals, and its stability is rigorously demonstrated via Lyapunov analysis. To improve dynamic performance across varying operating points, a gain-scheduling formulation is introduced, allowing the control gains to adapt as functions of the desired equilibrium state. The simulation results confirm that the proposed PI-PBC strategy provides accurate voltage regulation and fast transient response while ensuring continuous conduction. The controller exhibits robustness under reference changes and load disturbances, and the gain-scheduled designs outperform constant-gain implementations in terms of overshoot reduction and settling time.",

First, the Hamiltonian stabilizing control of IPMSM is realized using energy-shaping method of interconnection and damping assignment. Then the desired equilibrium is acquired by maximum torque per current(MTPA) and field-weakening control. Finally, the load torque observer is designed and the controller design is developed when the load torque is unknown. The simulation results show that the proposed method has good speed tracking performance and anti-disturbance ability in the full speed range, and the theory contributes to the improvement of control performance in the electric vehicle.",

      "abstract": "The paper proposes a control strategy which combines Active Disturbance Rejection Control (ADRC) and Passivity-Based Control (PBC) for Permanent Magnet Synchronous Motor (PMSM) sensor-less system. The Port-Controlled Hamiltonian with Dissipation (PCHD) model of PMSM is established, which uses the method of Interconnection and Damping Assignment PBC (IDA-PBC). Adjust the parameters of the current regulator to improve the robustness of the system. To reduce the steady-state error, the ADRC speed regulator is applied to the strategy. To estimate rotor speed and position, Model Reference Adaptive System (MRAS) method is adopted. The results of simulation show that the application of ADRC-PBC control strategy on sensor-less system of PMSM provides smaller steady-state error, better anti-jamming ability and better system dynamic performance.",

The control scheme is designed by the PCH control and L2 gain strategies. The calculating of the equilibrium point in the system uses the maximum torque/current principle below the base speed and the flux weakening principle above the base speed. Load torque disturbance always exists in the practical PMSM speed control system and using L2 gain to attenuate it. The PMSM speed control system is asymptotically stable. Simulation results show that the motor can achieve higher speed region with response rapidly, and has good attenuation ability to load torque disturbance.",

We formulate this problem as the Port-controlled Hamiltonian form, and a feedback control is introduced to symmetrize the non-symmetric part of the inertia matrix caused by the forward speed. And fault tolerant is necessary to be considered due to the fact communication faults occur in the complex ocean environment. In the presence of time-varying disturbances, the internal model is applied to tackle the uncertainties. The passivity enables the closed-loop systems to converge to steady states. Numerical simulation results are given to illustrate the effectiveness of the approach.",

A sliding mode control method combined with Port-Controlled Hamiltonian (PCH) is introduced to cope with the chattering problem of joint robot systems only controlled by the sliding mode control scheme. Firstly, the mathematical model of robot system and permanent magnet synchronous motor (PMSM) drive system are given in this paper. Then, the sliding mode control technique is utilized to design signal controllers for fast steady-state performance. And the PCH method is used for constructing energy controllers to decreasing energy losses. In addition, a coordination strategy is constructed to coordinate sliding mode control and PCH control for obtaining satisfactory control performance. Finally, the simulation results are presented to show the effectiveness of the method proposed in this paper.",

Firstly, the two degree of freedom mechanical arm system is transformed into a Port Controlled Hamiltonian (PCH) model, based on which we design its finite time observer system. Secondly, a robust stabilization controller based on finite time observer is designed by using dimension expansion technique and Lyapunov stability theory and some new robust stabilization results based on finite time observer are given. Different from existing stabilization results on the infinite-time observer, under the finite-time observer designed, the closed-loop system can converge quickly and has good robustness when it is disturbed by external environment.",

In this article, the designed adaptive Kalman filtering algorithm is utilized to estimate the image Jacobian matrix, reinforcing the robustness of the robot system. Dependent on this estimation, the visual servo controller is formulated, generating the joint control signal of the robot driven by direct current motors. Besides, considering energy transformation based control, error port-controlled Hamiltonian method is introduced to enhance the stability and accurate performance of joint servo control. Simulation and experimental results demonstrate that the designed control strategy achieves faster and more accurate location of the target.",

      "abstract": "This paper presents the design and performance evaluation of a passivity-based proportional-integral control (PIPBC) strategy for a single-phase pulse-width modulated current source converter (PWM-CSC) supplying a linear load. The control law is derived from a port-Hamiltonian representation of the converter in order to ensure asymptotic stability using a Lyapunov-based approach with component-wise error signals. To improve the transient response and the method's robustness under varying operating conditions, various gain scheduling strategies are examined, including constant gains, inverse scaling, and proportional scaling based on stored energy, as well as interpolation techniques using polynomial functions. The simulation results show that the proportional gain scaling method outperforms the other approaches in terms of the output current's dynamic response and its total harmonic distortion (THD). This strategy strikes a superior balance between settling time, overshoot, and harmonic attenuation, making it a strong alternative for high-performance power electronics applications. This study concludes with a comparative analysis of the implemented control schemes and provides some considerations for future hardware validation.",

      "abstract": "This paper focuses on power management strategy for a hybrid system involving the Fuel Cell (FC) as the main power source and the Supercapacitors (SCs) as the auxiliary power source. An innovative Passivity-based Control (PBC) strategy with multi-equilibrium states is proposed. The hybrid system is modeled as a Port-controlled Hamiltonian (PCH) system and then the operating modes and the corresponding multi-equilibrium states of the hybrid system are analyzed. Additionally, the proposed PBC is designed based on Interconnection and Damping Assignment (IDA) method and the stability of the closed-loop system is proven theoretically. The simulation results show that the proposed PBC could stabilize the DC bus voltage without any steady state errors and reasonably balance the power distribution between the FC and the SC.",

      "abstract": "This paper proposes an adaptive trajectory tracking control for an autonomous planar two-wheeled vehicle subject to nonholonomic constraints. Furthermore, the vehicle model considers a so-called positive trail that provides self-alignment of the steering in many vehicle types, including bicycles. The dynamics of the system is described in a port-Hamiltonian form that is suitable for systematic synthesis of passivity-based controllers. This also enables an explicit description of the system dynamics including the nonholonomic constraints by an ODE. By a generalized canonical transformation, an error system is determined preserving the port-Hamiltonian structure. This reduces the tracking problem to a stabilization problem that is solved by a further transformation. The controller is designed for a structure preserving simplified model and applied to the original model handling the omitted effects due to the simplification as disturbance. Finally, an adaptive controller is applied that, in the port-Hamiltonian framework, guarantees the asymptotic tracking of a given trajectory despite large parameter uncertainties.",

      "abstract": "This paper describes the application of the Port Controlled Hamiltonian Network for Modelling and Control of non-linear power system dynamics. Goal of this work is to propose a methodology for system level design for power electronics driven electrical networks able to guarantee large signal stability. Starting from a model-level modular approach, the system is defined using the interconnection concept. The paper focuses on a DC micro-grid scenario where several converters interact with a lumped load. Contrary to previous work, the load is modelled as a Constant Power Load (CPL) introducing new challenges in terms of system stability.",

      "abstract": "One of the major challenges of voltage stabilization in converter-based DC microgrids are the multiple interacting units displaying intermittent supply behavior. In this paper, we address this by a decentralized scalable, plug-and-play voltage controller for voltage-source converters (VSCs) at primary level. In contrast to existing approaches, we follow a systematic and constructive design based on port-Hamiltonian systems (PHSs) which does neither require the heuristic proposition of a Lyapunov function nor the computation of auxilliary variables such as time-derivatives. By employing the Hamiltonian naturally obtained from the PHS approach as Lyapunov function and using the modularity of passive systems, we provide sufficient conditions under which the designed VSC controllers achieve microgrid-wide asymptotic voltage stability. Integral action (IA), which preserves the passive PHS structure, robustifies the design against unknown disturbances and ensures zero voltage errors in the steady-state. Numerical simulations illustrate the functionality of the proposed voltage controller.",

To this end, a port-Hamiltonian formulation and a passivity-based control approach are employed. The main contribution is a new dynamic extension of the interconnection-and-damping assignment passivity-based control that only depends on the generalized position. Numerical simulations on an Acrobot system demonstrate that the proposed approach allows stabilizing the prescribed equilibrium by relying only on position feedback.",

      "abstract": "Passivity-based control (PBC) has shown to be very powerful to design robust controllers for physical systems described by Euler-Lagrange (EL) equations of motion. The application of PBC in regulation problems of mechanical systems yields controllers that have a clear physical interpretation in terms of interconnection of the system with its environment. In particular, the total energy of the closed-loop is the difference between the energy of the system and the energy supplied by the controller. Furthermore, since the EL structure is preserved in closed-loop, PBC is robust vis a vis unmodeled dissipative effects. Unfortunately, these nice properties are sometimes lost when PBC is used in other applications, for instance, in electrical and electromechanical systems. In this paper we further contribute to develop a new PBC theory encompassing a broader class of systems, and preserving the aforementioned energy-balancing stabilization mechanism and the structure invariance, continuing upon our previous work. Towards this end we consider port-controlled Hamiltonian systems with dissipation (PCHD), which result from the network modeling of energy-conserving lumped-parameter physical systems with independent storage elements, and strictly contain the class of EL models.",

In order to obtain a dynamic feedback, an integrator is added to the system firstly. Then the generalized canonical transformation is utilized to let the integrator play the role of an estimator of the unmeasurable state based on passivity. This technique can derive a time-varying output feedback stabilizing controller under a certain assumption. Furthermore the effectiveness of the proposed technique is demonstrated via a well known knife edge example.",

In particular, we obtain constructive sufficient conditions for hybrid feedback stabilization that provide a shaped energy function for the closed-loop system while preserving a hybrid Hamiltonian structure at the closed-loop level. Furthermore, an inverse optimal hybrid feedback control framework is developed that characterizes a class of globally stabilizing energy-based controllers that guarantee hybrid sector and gain margins to multiplicative input uncertainty of hybrid Hamiltonian systems.",

Since the introduction of this controller design methodology five years ago (1999), many theoretical extensions and practical applications have been reported in the literature. The theoretical developments include some variations and shortcuts that are useful when dealing with particular classes of systems, and the incorporation of additional features to handle control scenarios other than just stabilization. On the application side the method has provided solutions to a wide variety of physical problems. The purpose of this paper is to review the fundamental theory of this control system design approach. Main new results and practical applications as well as current open problems and future directions are discussed in a companion paper.",

The classical finite dimensional port Hamiltonian formulation of a dynamical system is generalized in order to cope with the distributed parameter and multivariable case. The resulting class of infinite dimensional systems is quite general, thus allowing the description of several physical phenomena, such as heat conduction, piezoelectricity and elasticity. Furthermore, classical PDEs can be rewritten within this framework. The key point is the generalization of the notion of finite dimensional Dirac structure in order to deal with an infinite dimensional space of power variables.",

The classical finite dimensional port Hamiltonian formulation of a dynamical system has been generalized to the distributed parameter and multivariable case by extending the notion of finite dimensional Dirac structure in order to deal with an infinite dimensional space of power variables. Consequently, it seems natural that also finite dimensional control methodologies developed for finite dimensional port Hamiltonian systems can be extended in order to cope with infinite dimensional systems. In this paper, the control by interconnection and energy shaping methodology is applied to the stabilization problem of a distributed parameter system by means of a finite dimensional controller. The key point is the generalization of the definition of Casimir function to the hybrid case, i.e. when the dynamical system to be considered results from the power conserving interconnection of an infinite and a finite dimensional part. A simple application concerning the stabilization of the one-dimensional heat equation is presented.",

A Stokes-Dirac structure can be extended to an externally supplied distributed energy besides an energy exchange through the boundary. First, we show that any disturbance can be decomposed into a boundary energy structure and a distributed energy structure. Next, the system representation is given by the decomposed structures. Finally, two examples are presented.",

      "abstract": "A novel class of fixed-order, energy-based hybrid controllers is proposed as a means for achieving enhanced energy dissipation in Euler-Lagrange, port-controlled Hamiltonian, and lossless dynamical systems. These dynamic controllers combine a logical switching architecture with continuous dynamics to guarantee that the system plant energy is strictly decreasing across switchings. The general framework leads to closed-loop systems described by impulsive differential equations. In addition, we construct hybrid dynamic controllers that guarantee that the closed-loop system is consistent with basic thermodynamic principles. In particular, the existence of an entropy function for the closed-loop system is established that satisfies a hybrid Clausius-type inequality. Special cases of energy-based hybrid controllers involving state-dependent switching are described.",

We show that under some mild assumptions, a new Hamiltonian can be found such that the system is again passive with respect to the new supply rate (y-y<inf>0</inf>)<sup>T</sup>(u-u<inf>0</inf>).",

      "abstract": "Either from a control theoretic viewpoint or from an analysis viewpoint it is necessary to convert smooth systems to discrete systems, which can then be implemented on computers for numerical simulations. Discrete models can be obtained either by discretizing a smooth model, or by directly modeling at the discrete level itself. The goal of this paper is to apply a previously developed discrete modeling technique to study the interconnection of continuous systems with discrete ones in such a way that passivity is preserved. Such a theory has potential applications, in the field of haptics, telemanipulation etc. It is shown that our discrete modeling theory can be used to formalize previously developed techniques for obtaining passive interconnections of continuous and discrete systems.",

Once the distributed port Hamiltonian (dpH) model of the plate is introduced, a simple boundary or distributed control methodology based on damping injection is discussed.",

A systematic controller design which maintains the Port Hamiltonian structure of the plant is demonstrated for the case of a double-ended piston with only one servovalve. The developed controller shows good robustness properties and is able to inject additional damping into the load system without velocity measurement.

First, we focus on dynamics with endlink mass perturbation after the settling time. Second, we derive the exact and explicit structured singular value for manipulators by using structural properties of the dynamics. The derived structured singular value is nothing but the structured singular value of manipulators without control because the passivity based control preserves the Hamiltonian structure. Furthermore, based on the derived structured singular value, we quantitatively analyze the robust stability and performance of robotic manipulators with the passivity based control",

It is structured into dissipative and conservative sub-systems related through a symplectic geometric structure which expresses instantaneous power conservation. This model is equivalent to the classical Saint-Venant equations (nonlinear PDEs also called shallow water equations) but trivially exhibits some interesting properties (passivity, stability, stored energy, entropy production) which may be useful for analysis or control purposes. Therefore the paper then focuses on a reduction scheme which preserves the geometric symplectic structure of the infinite dimensional model. This reduction scheme leads to a reduced port-controlled Hamiltonian finite-dimensional system which is compared with the infinite dimensional model and with other classical reduced models both in terms of spectral and energetic properties.",

It is known from Noether's theorem that a conservation law is associated with an invariant property called a symmetry. In certain cases, the symmetry appears in a system as a hidden infinite-dimensional structure. Such a structure can be defined by using a recursive operator consisting of a Hamiltonian pair and is called a bi-Hamiltonian structure. The bi-Hamiltonian structure induces a hierarchical set of conservation laws. This concept can be used for reducing a system possessing a bi-Hamiltonian structure to simpler port-representations of the conservation laws. Finally, a boundary observer for symmetry destruction is shown.",

A port-controlled Hamiltonian (PCH) representation is given for each component of the network. The corresponding linear model around the equilibrium point is shown to meet a convex condition in the frequency domain, able to be exploited in the stability analysis of interconnected systems. The application of this property to a classical two-areas example shows that it can be computationally exploited even in the case of non-idealized models.",

      "abstract": "This paper presents a new nonlinear passivity-based controller for a wound rotor synchronous machine, acting as a motor drive. From the standard dq-model the control objectives are stated, and the Port-controlled Hamiltonian model is also obtained. A simple power flow study allows to state the control goals in terms of reactive power compensation and ohmic losses reduction. Starting from the Hamiltonian structure, the Simultaneous Interconnection and Damping Assignment (SIDA-PBC) technique is used to develop the control action. The desired robustness of the control action is also taken into account in the design procedure. This results in a globally asymptotically stabilizing controller, which is validated via numerical simulations.",

SPHS's are extension of the deterministic port-Hamiltonian systems which are used to express various passive systems. First, we show a necessary and sufficient condition to preserve the stochastic port-Hamiltonian structure of the system under a class of coordinate transformations. Second, we derive a condition for the system to be stochastic passive. Third, we equip Stochastic Generalized Canonical Transformations (SGCT's), which are pairs of coordinate and feedback transformations preserving the stochastic port-Hamiltonian structure. Finally, we propose a stochastic stabilization framework based on stochastic passivity and SGCT's.",

First we look at the consequences for the matching equations when applying Inter-connection and Damping Assignment Passivity-Based Control (IDA-PBC). Then we look at the possibilities of asymptotically stabilizing a class of port-Hamiltonian mechanical systems without having to know the velocities, as once presented for Euler-Lagrange (EL) systems. Here it is shown how the idea of damping injection by dynamic extension works when shaping the total energy in the port-Hamiltonian framework.",

      "abstract": "Interconnection and damping assignment passivity-based control (IDA-PBC) is a technique that regulates the behavior of nonlinear systems assigning a desired (port hamiltonian) structure to the closed-loop. This basic idea, introduced eight years ago, has turned out to be very successful and has provided solutions to a wide variety of physical problems. Although IDA-PBC is originally formulated as a static state-feedback technique it can easily be reformulated to use dynamic controllers. A natural question that arises is whether it is possible to extend the realm of applicability of the method by considering dynamic controllers. More precisely, is the set of plants that is stabilizable with static state-feedback IDA-PBC smaller than the one stabilizable with dynamic IDA-PBC? The main contribution of this paper is to prove that the answer to this question is, unfortunately, negative.",

First, we show a geometrical structure of port variables determined by differential forms. Next, we state the necessary condition for regarding the distributed energy structure as a boundary energy structure which is boundary integrable. From these results, we define the fundamental form that generates the distributed port-Hamiltonian system with distributed energy structures in a variational problem. Finally, we present a new concept of boundary controls for the distributed port-Hamiltonian system with distributed energy structures in space-time coordinates.",

Inflatable structures have very nice properties, suitable for aerospace applications. We can construct e.g. a huge light weight reflector for a satellite which consumes very little space in the rocket because it can be inflated when the satellite is in the orbit. So with this technology we can build inflatable reflectors which are about 100 times bigger than solid ones. But to be useful for telescopes we have to actively control the surface of the inflatable to achieve the desired surface accuracy. The starting point of the control design is modeling for control, in the case port-Hamiltonian (pH) modeling. We show how to derive a nonlinear infinite dimensional pH model of a 1-D Euler-Bernoulli beam with piezo actuation. In the future we will also focus on 2-D models.",

The control law presented here is extension of an existing passive velocity field controller for fully actuated mechanical systems. The proposed method employs vector fields on the phase (co-tangent) spaces instead of those on the velocity (tangent) spaces. Since port-Hamiltonian systems can describe a wider class of systems than conventional mechanical ones, the proposed method is applicable to various systems. Furthermore, by making use of the port-Hamiltonian structure of the closed loop system, we can obtain a novel controller to assign the desired total energy. Moreover, a numerical simulation of a simple nonholonomic system exhibits the effectiveness of the proposed method.",

A local state decomposition (the nonlinear version of the Kalman decomposition) is instrumental for the approach that preserves the port-Hamiltonian structure. The strongly accessible reduction scheme goes along similar lines as the linear scheme. However, the observable reduction scheme is somewhat more involved. Under some additional assumptions, the reduction can be performed along the lines of the linear scheme. If these assumptions are not fulfilled, a reduction scheme for a zero-observable representation using duality in the co-energy coordinates is developed. Finally, the possibilities to apply the approaches of this paper to approximate order reduction by e.g., use of balancing procedures, is discussed.",

Based on the dissipation structure matrix of this port-Hamiltonian LuGre model, an alternative proof can be given for the passivity conditions that are known in the literature. As a specific example, the interconnection of a mass with the port-Hamiltonian LuGre model is presented. It is shown that the lossless interconnection structure and dissipation structure of the port-Hamiltonian LuGre model are consistent with those of the interconnection. Additionally, to render the friction model continuously differentiable, a smooth re-parametrization of the friction curve is proposed that extends and simplifies the existing results.",

      "abstract": "This paper is devoted to path following control for port-Hamiltonian systems whose desired path is time-varying. Most of the existing results on path following can only take care of time invariant paths, hence they cannot be applied to control systems whose environments change, e.g., path following control with moving obstacle avoidance or with a path crossing itself. The proposed method solves this problem by employing decoupling control of three particular directions in the phase space which allows one to assign time-varying potential functions and vector fields.",

      "abstract": "This paper illustrates a novel model reduction procedure for port-Hamiltonian systems able to preserve the frequency behavior of the original system in a neighborhood of a predefined set of frequencies of interest. This research is part of a wider activity carried out in collaboration with Tetra Pak concerning the modelling and simulation of the Ultrasonic Sealing System (USTS). Due to the presence of a Compact Transducer (CT) that can be modelled only by means of commercial finite element CAE software, which provide extremely high-order dynamical systems, it is not possible to perform a simulation of the complete system to test the validity of the controller and perform the diagnosis of the sealing process in detail. The proposed procedure drastically reduces the simulation time without loosing the essential dynamical information. The model reduction algorithm is validated, at first, by means of a simple benchmark (a beam with a pair of piezo-electric actuators on both sides) and then applied to one piezo-electric actuator of the CT. The application to the whole system is still under development.",

      "abstract": "Port network modeling of physical systems leads directly to an important class of passive state space systems: port-Hamiltonian systems. We consider here methods for model reduction of large scale port-Hamiltonian systems that preserve port-Hamiltonian structure and are capable of yielding reduced order models that satisfy first-order optimality conditions with respect to an H2 system error metric. The methods we consider are closely related to rational Krylov methods and variants are described using both energy and co-energy system coordinates. The resulting reduced models have port-Hamiltonian structure and therefore are guaranteed passive, while still retaining the flexibility to interpolate the true system transfer function at any (complex) frequency points that are desired.",

Characterization of such state discontinuities is a classical issue in circuit theory which, typically, is based on the so-called charge and flux conservation principle. This paper proposes a general state transfer principle for arbitrary switching port-Hamiltonian systems. This new principle coincides with the charge and flux conservation principle in the special case of linear RLC circuits, but also covers circuits with nonlinear capacitors and inductors, and of arbitrary topology. Moreover, the new principle is applied to switching mechanical systems.",

      "abstract": "The main contribution of this paper is a procedure for the control by energy shaping via Casimir generation of high-order port-Hamiltonian systems obtained from the spatial discretization of infinite dimensional dynamics. Beside the intrinsic difficulties related to the large number of state variables, the finite element model is generally given in terms of a Dirac structure and is completely a-causal, which implies that the plant dynamics is not given in standard input-state-output form, but as a set of DAEs. Consequently, the classical energy-Casimir method has to be extended in order to deal with dynamical systems with constraints, usually appearing in the form of Lagrangian multipliers. The methodology is illustrated with reference to a particular example, i.e. an hinged-hinged Timoshenko beam with torque actuators at both sides.",

In this paper it is shown how this power-based framework is used for control of standard mechanical systems. For systems which are affected by parameter uncertainty or other unknown disturbances adaptive control and integral control are also described in this framework. The power-based control approach is also compared with the energy-shaping control of port-Hamiltonian systems. The most interesting difference is the possibility of having adaptive and integrator dynamics depending on position errors, while preserving the physical structure.",

In a first instance we suggest a PCH formulation of the CSTR in the isothermal case, generated by a Hamiltonian being a reaction invariant with a Poisson structure matrix defined by the stoichiometric coefficients of the reaction or reaction network. In a second instance we include the energy balance equation and suggest a pseudo port Hamiltonian formulation with Hamiltonian function being either the internal energy or the entropy. In a third instance we consider the lift of the latter formulation on the whole Thermodynamic Phase Space and discuss two alternative formulations differing outside the Legendre submanifold associated with the thermodynamic properties of the CSTR.",

Using a port-Hamiltonian form of a quarter-car with LuGre tyre model, an energy shaping controller is constructed that stabilizes some desired relative (sliding) velocity. The measured variables are the friction force and the relative velocity. A stability analysis shows that this controller is robust against tyre-road friction uncertainties. A simplified control law is proposed that inherits the robustness characteristics of the original controller. Finally, this simplified controller is tested in a simulation environment, showing that the desired relative velocity is stabilized for different friction parameter values.",

Based on this system representation conditions for Casimir densities (functionals) will be derived where in this context the variational derivative plays an extraordinary role. Furthermore the coupling of finite and infinite dimensional systems will be analyzed in the spirit of the control by interconnection problem. Our Hamiltonian representation differs significantly from the well-established one using Stokes-Dirac structures that are based on skew-adjoint differential operators and the use of energy variables. We mainly base our considerations on a bundle structure with regard to dependent and independent coordinates as well as on differential-geometric objects induced by that structure.",

      "abstract": "This paper addresses the issue of structure-preserving discretization of open distributed-parameter systems with Hamiltonian dynamics. Employing the formalism of discrete exterior calculus, we introduce simplicial Dirac structures as discrete analogues of the Stokes-Dirac structure and demonstrate that they provide a natural framework for deriving finite-dimensional port-Hamiltonian systems that emulate their infinite-dimensional counterparts. This approach of discrete differential geometry, rather than discretizing the partial differential equations, allows to first discretize the underlying Stokes-Dirac structure and then to impose the corresponding finite-dimensional port-Hamiltonian dynamics. In this manner, we preserve a number of important topological and geometrical properties of the system.",

First, the interconnecting structure is not limited to the simple feedback case considered there, and this opens new possibilities for designing control systems. Second, the number of simultaneously interconnected systems is not limited to two, which allows for extra flexibility in modeling, particularly in the case of electrical networks. Several relevant particular cases are presented, and the application to the interconnection of port-Hamiltonian systems is discussed by means of an example.",

Using a local coordinate transformation, the effect of the homogeneous solution of the potential energy matching PDE is isolated. By comparison of desired local linear dynamics with the parametrized linearization of the closed loop dynamics a set of linear equations for the IDA-PBC design parameters is derived. Besides the possibility to assign predefined dynamics the definiteness check of the potential energy can be omitted. With an Acrobot-type mechanical system the design steps are illustrated and simulations validate the performance of the approach.",

In this paper, we develop a framework for model reduction of large-scale multi-input/multi-output nonlinear port-Hamiltonian systems that retains the port-Hamiltonian structure in the reduced order models. Within this framework, reduced order models are determined by the selection of two families of approximating subspaces. We consider two approaches deriving from a) a POD-based selection of subspaces, and b) an an ℋ2-based quasi-optimal selection of subspaces. We compare performance of the reduced order models on a nonlinear lossy LC ladder network.",

      "abstract": "Interconnection and damping assignment passivity- based control (IDA-PBC) is a nonlinear state feedback technique that endows the closed-loop system with a port-Hamiltonian (PH) structure. The assigned energy function qualifies as a Lyapunov function and thus can be used to estimate the domain of attraction (DA). However, determining the largest bounded sublevel set of a general energy function which is contained in the DA is a difficult task. In this paper, a numerical algorithm is developed to cope with this problem without formulating conditions on the energy function. Moreover, an optimization procedure is proposed to determine a controller parametrization which maximizes the estimated DA, while simultaneously taking account of desired closed-loop performance. An illustrative example is included, where also a comparison to a linear state feedback controller is presented.",

Once inputs and outputs have been properly chosen to have a well-posed boundary control system, conditions for the existence of Casimir functions in closed-loop are given, together with their relation with the controller structure. These invariants suggest how to select the controller Hamiltonian to introduce a minimum at the desired equilibrium. Such equilibrium can be made asymptotically stable via damping injection, if proper “pervasive” damping injection conditions are satisfied. The methodology is illustrated with the help of a Timoshenko beam with constant non-zero force applied at one side of the spatial domain, and full-actuation on the other one.",

      "abstract": "This paper proposes a method for designing set-point regulation controllers for a class of underactuated mechanical systems in Port-Hamiltonian System (PHS) form. A new set of potential shape variables in closed loop is proposed, which can replace the set of open loop shape variables-the configuration variables that appear in the kinetic energy. With this choice, the closed-loop potential energy contains free functions of the new variables. By expressing the regulation objective in terms of these new potential shape variables, the desired equilibrium can be assigned and there is freedom to reshape the potential energy to achieve performance whilst maintaining the PHS form in closed loop. This complements contemporary results in the literature, which preserve the open-loop shape variables. As a case study, we consider a robotic manipulator mounted on a flexible base and compensate for the motion of the base while positioning the end effector with respect to the ground reference. We compare the proposed control strategy with special cases that correspond to other energy shaping strategies previously proposed in the literature.",

The overall system is first modelled as a boundary controlled port Hamiltonian system made up as the interconnection of an infinite dimensional system (modelled as an undamped Timoshenko beam) representing the flexible arm of the gripper with two finite dimensional systems representing the DNA bundle and the suspension/actuator mechanism. The base of the arm is clamped on the suspension mechanism leading to under actuated system. The controller considered under strict dissipative port Hamiltonian format uses the velocity of the base of the tweezers arm as input and generates a force as output. The exponential stability of the closed loop system is derived by checkininfinite and finite dimensional system.g simple conditions on both the infinite and finite dimensional system.",

In this paper we show that by use of a Memristive element in the controller design enables us to generate additional Casimir functions relating the state of the memristor to the plant state. This additional conserved quantity manifests itself in the control law in form of a state-modulated gain. We present our results with examples in the context of control by Casimir generation in the port-Hamiltonian framework, which essentially deals with shaping the energy of the system. We also present the applicability of the results towards control by power shaping of electrical circuits in the Brayton-Moser framework for modeling of electrical networks.",

      "abstract": "In this paper position control strategies via force feedback are presented for standard mechanical systems in the port-Hamiltonian framework. The presented control strategies requires a set of coordinate transformations, since force feedback in the port-Hamiltonian framework is not straightforward. With the coordinate transformations force feedback can be realized while preserving the port-Hamiltonian structure. The port-Hamiltonian formalism offers a modeling framework with a clear physical structure and other properties that can often be exploited for control design purposes, which is why we believe it is important to preserve the structure. The proposed control strategies offers an alternative solution to position control with more tuning freedom and exploits knowledge of the system dynamics.",

We use the Dynamic Extension Algorithm to the system. The dynamic extended system becomes an input affine system so that the tracking controller is obtained in input-output linearization framework. The tracking control law is generated considering the stability and performance of the input output linearized dynamics. We apply it to a static synchronous compensator (STATCOM) system, which is not an input affine system. We make a dynamic extension of the STATCOM system to conveniently design a reference output and then put the dynamics into the form of port-controlled Hamiltonian to apply the proposed tracking controller. Simulation results show that the proposed method improves the transient performance of the system over the previous results even in the lightly damped operating range.",

      "abstract": "It is widely accepted in the literature that magnetic effects in the piezoelectric beams is relatively small, and does not change the overall dynamics. Therefore, most models for piezoelectric beams completely ignore the magnetic energy. These models are known to be exponentially stabilizable by a mechanical feedback controller in the energy space. In this paper, we use a variational approach to derive the differential equations and boundary conditions that model a single piezoelectric beam with magnetic effects. Next, we show that the resulting control system can be formulated as a port-Hamiltonian system and is hence well-posed. Finally, by using only an electrical feedback controller (the current flowing through the electrodes), we show that the closed-loop system is strongly stable in the energy space for a dense set of system parameters. The difference between this result and that for models that neglect magnetic effects is discussed.",

Particularly, we are interested in incorporating an exponentially stable response to a robust passivity-based control design. We formulate and analyse the stability of the proposed controllers based on the port-Hamiltonian framework. One of the novelties of the presented control design, is that exponential stability is achieved without removing the natural non-linearity of the mechanical system. To the best of our knowledge, this is the first time an exponentially stable controller is reported with this passivity-based method.",

A conservative discrete linear port-Hamiltonian dynamics involving a modified conjugate port-output is introduced. It is shown that the projection yielding the discrete dynamics and the composition by canonical interconnection commute. As a by-product, symplecticity of the numerical flow is preserved by interconnection whenever input vector fields are Hamiltonian vector fields, which is analogous to the continuous case. The negative feedback interconnection of two circuits illustrates the results.",

Usually, stabilisation of non-zero equilibria has been achieved by looking at, or generating, a set of structural invariants, namely Casimir functions, in closed-loop. Since this approach fails when an infinite amount of energy is required at the equilibrium (dissipation obstacle), this paper illustrates that the class of stabilising controllers is enlarged if the synthesis relies on the parametrisation of the dynamics provided by the image representation of the Dirac structure, able to show the effects of the boundary inputs on state evolution. The theoretical results are discussed with the help of a simple but illustrative example, i.e. a transmission line with RLC load in both serial and parallel configurations.",

Two general cases are considered, when the system is (i) linear time-invariant or (ii) nonlinear, with dynamic behavior described by a port-Hamiltonian model with constant dissipation and switching interconnection matrix. The latter class includes the practically important case of power converters.

      "abstract": "This paper aims at extending the port-Hamiltonian formalism to a simple class of macro-economic systems. As in physical modelling, for these systems, the dynamics is the result of the interaction between a limited set of “atomic components,” such as inventories, (re)investments, suppliers and demand. Once flow, effort, and “power” (i.e., the cash flow) have been defined, the behaviour of these simple elements is provided, and their interconnection is described in terms of a Dirac structure, whose power conservation property is recognised as the equivalent of the law of good bookkeeping, i.e. the Walras's Law, in economy. Then, port-Hamiltonian and Brayton-Moser descriptions of the system dynamics is obtained by port interconnection, as usually done in case of physical systems. Some example are provided to explain not only the potentialities, but also the limitations of the proposed approach.",

We design our system using port-Hamiltonian theory and the bondgraph modelling technique. Our approach builds upon the architecture presented in [22], which relied on partial measurements of relative position rather than position measurements with respect to an inertial frame. The previous work used a generalised form of the image Jacobians employed in image-based visual servo (IBVS) control literature to compute the desired control forces. However, the implementation of these measurement Jacobians requires unknown information about the relative positions of the vehicles. A key contribution of this paper is that we show how a depth observer can be integrated into the design to overcome this problem for the case where bearing measurements are available. Assuming that a single distance measurement is also available, we can specify a rigid goal formation in terms of the available measurements of relative positions. For this system, we prove local convergence to the desired configuration. We then provide a discussion regarding the implementation, and suggest that in practice, the distance measurement may be unnecessary. This discussion is supported by simulation results.",

      "abstract": "Aerial Manipulators (AMs) are a special class of underactuated mechanical systems formed by the join of Unmanned Aerial Vehicles (UAVs) and manipulators. A thorough analysis of the dynamics and a fully constructive controller design for a quadrotor plus n-link manipulator in a free-motion on an arbitrary plane is provided, via the lDA-PBC methodology. A controller is designed with the manipulator locked at any position ensuring global asymptotic stability in an open set and avoiding the AM goes upside down (autonomous). The major result of stability/robustness arises when it is proved that, additionally, the controller guarantees the boundedness of the trajectories for bounded movements of the manipulator, i.e. the robot manipulator executing planned tasks, giving rise to a non-autonomous port-controlled Hamiltonian system in closed loop. Moreover, all trajectories converge to a positive limit set, a strong result for matching-type controllers.",

      "abstract": "This work is devoted to an impedance grasping strategy for a class of standard mechanical systems in the port-Hamiltonian framework. The presented control strategy requires a set of coordinate transformations, since the impedance control in the port-Hamiltonian framework with structure preservation is not straightforward. The impedance grasping control is achieved via a virtual spring with a variable rest length. The force that is exerted by the virtual spring leads to a dissipation term in the impedance grasping controller which is needed to obtain a smoother noncontact to contact transition. Simulations results are given in order to motivate our results.",

We propose a new definition of algebraic solution of the so-called matching equation. This notion is instrumental for the construction of an energy function on an extended state-space, which does not rely on the solution of any partial differential equation. We provide sufficient conditions that allow to preserve the port-Hamiltonian structure in the extended closed-loop system. The theory is validated on an electrostatic microactuator by assigning an interconnection and damping structure that cannot be imposed with the standard approach.",

      "abstract": "In this paper we present some new results on two energy-shaping controllers for port-Hamiltonian (pH) systems: Control by Interconnection (CbI) and Energy-Balancing Passivity-Based Control (EB-PBC). The work is motivated by two recent developments, first, the identification of a novel class of passive outputs for pH systems. Second, the observation that allowing the energy function of the controller used in CbI to depend on the state of the system to be controlled also generates new passive outputs. As shown here, using these passive outputs gives additional degrees of freedom for the design of CbI and EB-PBC to make both techniques more widely applicable. Another contribution of the paper is to provide an unified framework for the design of the various forms of CbI and EB-PBC reported in the literature, objective that is achieved viewing EB-PBC as a particular instance of CbI with regulated sources.",

On the basis of a Lyapunov-Krasovskii functional and the Wirtinger's inequality (known to be less conservative than the popular Jensen's inequality) we show the improvements of the newly proposed criterion with respect to other existing ones. The stability analysis is derived based on a delay independent criterion. A classical nonlinear example taken from the literature illustrates the relevance of the results.",

      "abstract": "This paper aims at extending a novel approach based on the port-Hamiltonian formalism and able to model macro-economic systems to include a more realistic formulation of the firm (or supplier) behaviour. The firm is a profit maximising entity, naturally described in terms of a contact structure, that interconnects the markets associated to the demand and to the input factors in order to create a profit. To determine the resulting dynamics, the paper shows how to interconnect the port-Hamiltonian systems associated to each market with contact structures, i.e. how to combine power conserving interconnecting structures, namely Dirac structures (related to the Walras's Law of macro-economic), with contact structures, usually employed to describe irreversible phenomena. Beside the specific application to macro-economy, since a contact structure can be associated to a sort of “energy-based” maximisation/minimisation problem, it is also shown how to achieve such kind of interconnection via feedback control, i.e. how to shape a power-conserving interconnection to obtain a contact structure.",

The PHS structure is used to design a controller that rejects unmatched constant disturbances from non-passive outputs. In the PHS framework, the disturbance rejection problem has been addressed adding integral action and using a change of coordinates. In our approach, we avoid a change of coordinates keeping the original state vector, which contains variables with physical interpretation. The methodology proposed in this paper is illustrated on an electrical circuit and on a permanent magnet synchronous motor. Simulation of the later example shows the performance of the control design.",

The energy-shaping control action is based on the so-called control by interconnection and Casimir generation methodology (energy-Casimir method), here extended to deal with distributed port-Hamiltonian systems with 2D domain. On the other hand, the L2-gain property is obtained via damping injection by modulating a gain associated to a dissipative relation. Such approach takes inspiration from the Passivity Observer / Passivity Controller (PO / PC) technique originally developed for telemanipulation systems. Even if the proposed framework is quite abstract and general, possible target applications deal with the stabilisation of flexible structures, or with the stabilisation and attenuation of sound propagation in rectangular cavities.",

This approach can be applied to a large class of port-Hamiltonian systems, both in the lumped, and in the distributed parameter cases. It is also shown how the limitations of the control by interconnection and energy-shaping via Casimir generation can be removed by interconnecting the controller to a different control port, i.e. how it is possible to compute a new passive output that is instrumental for removing the intrinsic constraints imposed by the dissipative structure of the system.",

      "abstract": "This paper studies the problem of frequency regulation in power grids, while maximizing the social welfare. Two price-based controllers are proposed; the first one an internal-model-based controller and the second one based on a continuous gradient method for optimization. Both controllers can be implemented in a fully distributed fashion, with freedom in choosing a controller communication network. As a result, two real-time dynamic pricing models described by port-Hamiltonian systems are obtained. By coupling with the port-Hamiltonian description of the physical network we obtain a closed-loop port-Hamiltonian system, whose properties are exploited to prove asymptotic stability of the set of optimal points. Numerical results show the performance of both controllers in a simple case study.",

This work concerns the class of Newtonian mechanical port-Hamiltonian systems (PHSs), that is those having separable energy being quadrating in momentum (with constant mass matrix). We first introduce a discretization scheme which ensures a passivity equation relatively to the same storage and dissipation functions as the continuous-time PHS. A discrete controller is then obtained following the IDA-PBC design procedure applied to the discrete PHS system. This method guarantees that, from an energetic viewpoint, the discrete closed-loop behavior is similar to the continuous one. Under zero-state observability assumption, closed-loop stability then follows from LaSalle principle. The method is illustrated on an inertia wheel pendulum model.",

One of the advantages of the proposed method is its ability to utilize the stabilization results for the purpose of tracking. For many systems, when the stabilization problem is solved via the common IDA-PBC method, using some simple modifications on the closed-loop Hamiltonian function, the tracking problem can also be solved through the Timed IDA-PBC technique.",

      "abstract": "Equilibrium stabilisation of nonlinear systems via energy shaping is a well-established, robust, passivity-based controller design technique. Unfortunately, its application is often stymied by the need to solve partial differential equations. In this paper a new, fully constructive, procedure to shape the energy for a class of port-Hamiltonian systems that obviates the solution of partial differential equations is proposed. Proceeding from the well-known passive, power shaping output we propose a nonlinear static state-feedback that preserves passivity of this output but with a new storage function. This function contains some tuning gains used to ensure it is positive definite, hence a suitable Lyapunov function for the closed-loop. Connections with other standard passivity-based controllers are indicated and it is shown that the new controller design is applicable to two benchmark examples.",

This class of systems is motivated by the problem of stability in droop-controlled microgrids with delays. Delay-dependent stability conditions are derived via the Lyapunov-Krasovskii method. The stability conditions are applied to an exemplary microgrid. The efficiency of the results is illustrated via a simulation example.",

      "abstract": "In this paper, for a class of distributed port-Hamiltonian systems defined on a one-dimensional spatial domain, an equivalent Brayton-Moser formulation is provided. The dynamic is expressed as a gradient equation with respect to a new storage function, the “mixed-potential,” with the dimensions of power. The system is then passive with respect to a supply rate that is related to the reactive power, and that depends on the boundary port variables and on their time derivatives. This equivalent representation is the starting point for the development of boundary control laws able to shape the mixed-potential function. Differently from energy-balancing control schemes, this technique allows to deal with pervasive dissipation in the system in an effective way. The general theory is illustrated with the help of an example, the boundary stabilisation of a transmission line with internal dissipation.",

The energy-Casimir method is the starting point to determine a state-feedback law able to shape the closed-loop Hamiltonian and achieve simple stability. Then, it is shown how to design a further control loop that guarantees exponential convergence. Thanks to this result, it is possible to overcome a limitation of standard damping injection strategies that, if combined with energy shaping control laws based on energy-balancing, are able to assure, in general, only asymptotic convergence. The methodology is illustrated with the help of a simple example, the boundary stabilisation of a lossless transmission line.",

By analyzing the physical energy stored in the network and the generators, a port-Hamiltonian representation of the multi-machine system is obtained. Moreover, it is shown that the open-loop system is passive with respect to its steady states which allows the construction of passive controllers to control the multi-machine network. As a special case, a distributed consensus based controller is designed that regulates the frequency and minimizes a global quadratic generation cost in the presence of a constant unknown demand. In addition, the proposed controller allows freedom in choosing any desired connected undirected weighted communication graph.",

In this paper first the formulation and extension of negative imaginary and counter-clockwise systems as (nonlinear) input-output Hamiltonian systems with dissipation is summarized. Next it is shown how by considering the time-derivative of the outputs a port-Hamiltonian system is obtained, and how this leads to the consideration of alternate passive outputs for port-Hamiltonian systems. Furthermore, a converse result to positive feedback interconnection of input-output Hamiltonian systems with dissipation is obtained, stating that the positive feedback interconnection of two linear systems is an input-output Hamiltonian system with dissipation if and only if the systems themselves are input-output Hamiltonian systems with dissipation. This implies that the Poisson and resistive structure matrices can be redefined in such a way that the interaction between the two systems only takes place via the coupling term in the Hamiltonian of the interconnected system. Subsequently, it is shown how the positive feedback interconnection of two nonlinear input-output Hamiltonian systems with dissipation can be extended to the network interconnection of such systems, and how this leads to a stability analysis of the interconnected system in terms of the Hamiltonians and output mappings of the component systems associated to the vertices, as well as of the network topology.",

The main contribution consists of proposing an alternative power loss function by means of a change of variables that translates the convex objective function into a strictly convex objective function. The results hold under some restrictive assumptions, but necessary to make steps towards a complete algorithm in future research. The obtained results are validated via numerical simulations.",

The main novelty lies in fact that the structural invariants are not used to shape the closed loop energy function but to modify the closed loop structure of the system by an appropriate choice of the controller structure. In particular it is shown that in the fully actuated case, this control strategy allows to transform an hyperbolic system composed of two conservation laws into a parabolic one. This work is illustrated on the example of the wave equation but can be easily generalised to a large class of systems encompassing vibrating strings and beam equations.",

      "abstract": "This paper presents a novel approach for the development of boundary control laws for a class of linear, distributed port-Hamiltonian systems, with one dimensional spatial domain. The idea is to determine a control action able to map the initial system into a target one, characterised not only by a different Hamiltonian function, but also by new internal dissipative and power-preserving interconnection structures. The methodology consists of two main steps, each associated to a generalised canonical transformation. In the first one, a coordinate change (based on a combination of a linear mapping and a backstepping transformation) is employed to modify the internal structure of the system. Then, in the second step, a generalised canonical transformation capable of properly shaping the Hamiltonian function is introduced. The proposed approach is illustrated with the help of an example, the boundary stabilisation of a lossless transmission line.",

      "abstract": "Backstepping boundary control is investigated for a class of linear port-Hamiltonian systems. It is shown that by considering as target system an exponentially stable dissipative PHS, i.e. a PHS with a linear dissipation term and homogeneous boundary conditions, a coordinate transformation based on a multiplicative operator suffices to map the open-loop system into the target system. The condition for the existence of the transformation is algebraic. Hence, the backstepping transformation and the associated matching condition are simpler than the conventional ones that considers Volterra integral terms and kernel conditions in the form of partial differential equations. Since the controller has been developed for a general class of linear PHS it is applicable to a large class of physical systems, as for instance transport, beam and wave equations. The result is illustrated on the examples of a transport equation and a vibrating string on a 1D spatial domain.",

      "abstract": "This paper deals with two different topics that, at a first sight, could look quite unrelated. The first one is about repetitive control: the scope is to determine a class of linear systems for which such control technique can be successfully applied, i.e. the resulting closed-loop system is stable. In repetitive control schemes, coupled PDEs and ODEs are present, and the idea is to rely on a port-Hamiltonian formulation, and on the properties of passive/dissipative systems to study the behaviour of the closed-loop dynamic. To perform this analysis, novel results dealing with the exponential stabilisation of linear boundary control system with one-dimensional spatial domain in port-Hamiltonian form via finite dimensional linear controllers are presented. This is in fact the second topic discussed in this paper, and the achieved results are applied in order to characterise a class of linear systems for which repetitive control schemes exponentially converge.",

The conventional path following control method needs to find a time invariant potential function which takes its minimum on the desired path. It is so difficult to find a potential function for a complex path. Inspired by the results of existing trajectory tracking control of port-Hamiltonian systems, we propose an improved path following control method. By solving partial differential equations, a potential function for path following control is acquired.",

As a result, the stability of the system is guaranteed if the rest of the system that the power electronic converter connects to is passive. The controller consists of two control loops, which form a passive port-Hamiltonian (PH) system, and one lossless block, which interconnects the passive block with the plant. In order to facilitate the implementation of the framework, a new word quorte is coined to represent the quantity that is dual to the torque. Simulation results are presented to demonstrate the effectiveness of the control framework in both grid-connected and islanded modes.",

The highly nonlinear response of dielectric elastomer material, in conjunction with the bi-stable biasing spring, makes the control of the overall system challenging. To systematically address the design of the control system, a novel approach is proposed based on port-Hamiltonian (PH) theory. First, based on a recently developed PH model of the dielectric elastomer material, a PH model of the overall actuator system is obtained. Subsequently, several control laws are designed by means of PH theory, i.e., interconnection and damping assignment passivity-based control (IDA-PBC), and IDA-PBC with integral of non-passive output for robust regulation. The developed control laws are finally compared with a conventional PID, showing improved dynamic performance in the overall actuation range.",

The observer convergence is addressed by systematically determining the output injection so that the observer error dynamics takes the form of an autonomous, passive port-Hamiltonian system. In this respect, the design resembles the interconnection and damping assignment passivity-based controller (IDA - PBC) used for the feedback stabilization of port-Hamiltonian systems. The observer performance is analyzed and illustrated in simulation examples.",

By using Bayesian inference, not only the mean value of the trajectory but also the covariance matrix is acquired. By incorporating the covariance information into the control system design, it is expected to create a potential function that takes into account uncertainty at each position on the trajectory.",

Thanks to the port-Hamiltonian formalism the models proposed here have a particular structure that makes them plug-in and modular, so that they can be interconnected for building holistic models for faulty water distribution networks.",

      "abstract": "In this paper, we propose a decentralized scalable, plug-and-play control of voltage-source inverters (VSIs) in islanded, inverter-based AC micro-grids at primary level. Particularly in islanded mode without inertia from conventional generators in the main grid, voltage and frequency stabilization must be performed exclusively by these VSIs. In contrast to existing approaches, we propose a systematic procedure that does not require the proposition of a Lyapunov function as well as avoids computationally expensive and possibly infeasible numerical optimization. It follows passivity techniques, namely interconnection and damping assignment passivity-based control (IDA-PBC) on the basis of port-Hamiltonian systems (PHSs) theory. By employing the Hamiltonian naturally obtained from the PHS approach as Lyapunov function and analyzing load dynamics, we prove microgrid-wide asymptotic voltage and frequency stability. A simulation validating our theoretical results concludes our work.",

      "abstract": "The Kirchhoff plate model is detailed by using a tensorial port-Hamiltonian (pH) formulation. A structure-preserving discretization of this model is then achieved by using the partitioned finite element (PFEM). This methodology easily accounts for the boundary variables and the finite-dimensional system can be interconnected to the surrounding environment in a simple and structured manner. The algebraic constraints to be considered are deduced from the boundary conditions, that may be homogeneous or defined by an interconnection with another pH system.The versatility of the proposed approach is assessed by means of numerical simulations. A first illustration considers a rectangular plate clamped on one side and interconnected to a rigid rod welded to the opposite side. A second example exploits the collocated output feature of pH systems to perform damping injection in a plate undergoing an external forcing. A stability proof is obtained by the application of the LaSalle’s invariance principle.",

      "abstract": "In this paper we consider the feedback equivalence of homogeneous Hamiltonian control systems. These systems are Hamiltonian control systems which are generated by Hamiltonian drift (autonomous) and control Hamiltonian functions that are homogeneous of degree 1 in the momentum variables, and arise in the Hamiltonian model structure of open thermodynamic systems. It may be shown that the homogeneity conditions can be translated as the invariance of the Liouville 1form. We consider the problem of characterizing classes of state feedbacks for which the closed-loop system is again Hamiltonian and leaves invariant some closed-loop 1-form. In the case when the open- and closed loop 1-forms differ by an added 1-form which is exact, we derive matching equations between the generating function of the added 1-form and the added Hamiltonian function. This approach is applied to the simple example of a non-isothermal mass-spring-damper system.",

      "abstract": "We propose a framework based on port-Hamiltonian modeling formalism aimed at learning interaction models between particles (or networked systems) and dynamical properties such as trajectory symmetries and conservation laws of the ensemble (or swarm). The learning process is based on approaches and platforms used for large scale optimization and uses features such as automatic differentiation to compute gradients of optimization loss functions. We showcase our approach on the Cucker-Smale particle interaction model, which is first represented in a port-Hamiltonian form, and for which we re-discover the interaction model, and learn dynamical properties that are previously proved analytically. Our approach has the potential for discovering novel particle cooperation rules that can be extracted and used in cooperative control system applications.",

The two estimators are applied to an estimation problem in an electric power system. Numerical simulations proof the validity of the proposed methods.",

In this paper, we use a port-Hamiltonian representation of marine vehicles to develop a passivity-based controller for the suppression of unknown input wave disturbances using a harmonic representation while tracking a time varying reference signal. Our controller is an extension of the tracking controller of [1], with the addition of the input disturbance suppression using an internal model unit from [2]. We show exponential stability for the tracking controller, and utilise Barbalat’s Lemma to show that all the signals in the input disturbance suppression controller are bounded. We illustrate our results through simulations.",

      "abstract": "Recently, the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) methodology has been extended to underactuated mechanical systems in implicit port-Hamiltonian representation. The method is not restricted to holonomic systems, does not require a positive-definite target inertia matrix and, under general conditions, avoids the need for solving partial differential equations. In this paper we simplify the conditions for (local) stability and present equivalent matching equations. In addition, we exploit the inherent polynomial structure of implicit systems modeled in Euclidean space, such that the implicit IDA-PBC problem can be cast as a linear matrix inequality problem. The method is applicable to desired Hamiltonians with arbitrary polynomial order. The proposed methodology is validated on the portal crane and the cart-pole system.",

      "abstract": "In this contribution, we apply a spatial structure– preserving discretization scheme to a 1–D burning plasma model. The plasma dynamics are defined by a set of coupled conservation laws evolving in different physical domains, matching the port–Hamiltonian formalism in infinite dimension. This model describes the time evolution of magnetic, thermic, and material plasma profiles. A structure–preserving spectral collocation method is used to discretize the set of Partial Differential Equations (PDEs) into a finite–dimensional port– Hamiltonian system, a set of Ordinary Differential Equations (ODEs). The discretization scheme relies on the conservation of energy, based upon the transformation of Stokes–Dirac structures onto Dirac ones. Transport models and couplings are chosen to match with the experimental Tokamak ITER. Among the couplings, we include bootstrap and ohmic currents, ion–electron collision energy, radiation loses, and the fusion reaction. The obtained control model is compared with two steady–state operation points obtained from a physics–oriented plasma simulator.",

      "abstract": "This paper deals with an application of active control of percussion instruments. Our setup consists of a tom-tom drum with a circular membrane, a cylindrical cavity and a circular rigid wall on which a loudspeaker is mounted. The current applied to the loudspeaker is controlled in order to modify the frequencies of the drum membrane modes. First, a PDE model of the axisymmetric transverse vibration of the tom-tom membrane is developed. Subsequently, the equation is recast as an infinite-dimensional port-Hamiltonian system. The port-Hamiltonian framework enables us to develop a numerical scheme that preserves the power balance and guarantees a stable simulation. Finally, a control law for the loudspeaker current is designed to modify the frequency of the first axisymmetric vibration mode of the drum membrane, using finite-time and passivity-based methods.",

      "abstract": "We consider the port-Hamiltonian formulation of systems of two conservation laws with canonical interdomain coupling in one spatial dimension. Based on the structure-preserving discretization in space and time, we propose two directions for the estimation of the discrete states from boundary measurement. First, we design full state Luenberger observers for the linear case. To guarantee unconditional asymptotic stability of the discrete-time error system, special attention is paid to the implementation of the correction term in the sense of implicit damping injection. Second, we exploit the flatness of the considered class of possibly nonlinear hyperbolic systems, which is preserved under the applied geometric discretization schemes, to obtain a state estimation based on boundary measurement. Numerical experiments serve as a basis for the comparison and discussion of the two proposed discrete-time estimation schemes for hyperbolic conservation laws.",

A geometric reduction by symmetry is obtained, simplifying the system to one-dimension. The recently developed Partitioned Finite Element Method is applied to semi-discretize the equations, preserving the boundary power-product of both the original 2D and the reduced 1D system. The main advantage of this power-preserving semi-discretization method is that it can be applied using well-established finite element software. In this work, we use FEniCS to solve the variational formulation, including the nonlinearity provided by the non-quadratic Hamiltonian of the SWE. A passive output-feedback controller using damping injection is used to dissipate the water waves.",

      "abstract": "In this paper we present an irreversible port-Hamiltonian model for describing the hysteresis in thermal shape memory alloy (SMA) wire actuators. In contrast to most mechatronic actuators which are operated under isothermal conditions, SMA wires must be heated with an electric current to generate a stroke. As a result of the non-isothermal activation, concepts such as energy dissipation no longer hold from a thermodynamic viewpoint, thus making it difficult to quantitatively analyze the relationship between SMA hysteresis and system stability. Starting from a physics-based model of the SMA based on the work of Müller-Achenbach-Seelecke, a candidate Helmholtz free-energy function is first proposed to describe the material under non-isothermal condition. Based on this result, the system internal energy is constructed and used as a storage function for an irreversible port-Hamiltonian representation. The developed model permits to quantify the energetic performance of SMA wires during non-isothermal actuation, as well as to assess the system thermodynamic consistency based on irreversible entropy production. In addition, the model represents the first step towards the design of energy-based control systems for hysteresis compensation.",

      "abstract": "Neural networks are discrete entities: subdivided into discrete layers and parametrized by weights which are iteratively optimized via difference equations. Recent work proposes networks with layer outputs which are no longer quantized but are solutions of an ordinary differential equation (ODE); however, these networks are still optimized via discrete methods (e.g. gradient descent). In this paper, we explore a different direction: namely, we propose a novel framework for learning in which the parameters themselves are solutions of ODEs. By viewing the optimization process as the evolution of a port-Hamiltonian system, we can ensure convergence to a minimum of the objective function. Numerical experiments have been performed to show the validity and effectiveness of the proposed methods.",

      "abstract": "We use energy conservation and power flows in port-Hamiltonian systems to develop a system identification procedure for linear time-varying systems. The basic idea is to use external energy flows to obtain information on internal energy storage, and hence state trajectories. Given N input and output trajectories (uk, yk ), k = 1, … , N of a linear port- Hamiltonian system, and additional information on resistive variables, a set of state trajectories xk, k = 1, …, N is computed via factorisation of a matrix of functions constructed from the external information. The basis transformation associated with a canonical factorisation of this matrix is discussed.",

This structure is associated with a Dirac structure that encloses its energy balance properties. In particular, port-Hamiltonian systems are naturally passive and Lyapunov stable, because the Hamiltonian defines a Lyapunov function. The explicit representation of input and dissipation in the structure make these systems particularly suitable for output feedback control. It is shown that this structure is invariant under a wide class of nonlinear transformations, and that it can be naturally modularized, making it adequate for automated modeling. We investigate then the application of time-discretization schemes to these systems and we show that, under certain assumptions on the Hamiltonian, structure preservation is achieved for some methods. Relevant examples are provided.",

Differently from most related literature, the system’s controlled output is taken as the power—not the current—injection at each generation unit, yielding a nonlinear closed-loop system. This makes the output regulation problem non-trivial, yet far more appealing in a practical setting than the usual linear current-voltage droop control. Our approach is inspired by passivity-based control design in the sense that we exploit the natural port-Hamiltonian representation of the system dynamics and its associated shifted Hamiltonian to derive a control law together with sufficient conditions on the tuning gains that guarantee global asymptotic stability. The analysis is illustrated via detailed simulations, where accurate power sharing is manifested among the distributed generation units in the presence of load variations.",

      "abstract": "In this paper we consider the stabilization problem of a beam clamped on a moving inertia actuated by an external torque and force. The beam is modelled as a distributed parameter port-Hamiltonian system (PDEs), while the inertia as a finite dimensional port-Hamiltonian system (ODEs). The control inputs correspond to a torque applied by a rotating motor and a force applied by a linear motor. In this paper we propose the use of a strong dissipation term in the control law, consisting of the time derivative of the restoring force at the clamping point. After a change of variables, the closed loop system shows dissipation at the boundaries of the PDEs. In this preliminary work we show that the closed loop operator is the generator of a contraction C0-semigroup in a special weighted space, with norm equivalent to the standard one. Further, we prove the asymptotic stability of the closed loop system and we show the effectiveness of the proposed control law in comparison with a PD controller with the help of numerical simulations.",

We introduce the port-Hamiltonian representation of this two-phase flow model and then invoke a mixed-finite-element method to perform a structure-preserving spatial discretization. Consequently, we obtain a finite-dimensional realization of a recently proposed novel Stokes-Dirac structure for this model. The properties of the resulting finite-dimensional realization are assessed and the conditions under which it is known to respect the properties of a finite-dimensional Dirac structure are discussed. Moreover, we derive the complete finite-dimensional interconnected port-Hamiltonian model by invoking the notion of power-preserving interconnection.",

      "abstract": "The self-excited induction generator presents important advantages for isolated generation systems ranging from low cost to simplicity of construction, operation, and maintenance. The complexity of the output voltage regulation problem for the generator is due to the nonlinear dynamics effects in presence of variable systems loads. The main contribution of the current work is first a generalization of the modeling approach to the self-exited squirrel-cage induction generator which is based on a stationary d-q frame of reference. The modeling approach is done via an energy-based strategy, more specifically, the port-Hamiltonian framework. Furthermore, we present here a novel control law based on a trajectory tracking strategy in order to attain asymptotic stability on a time-variant desired voltage at the output of the generator. The control action based on a so-called error system approach is focused on an exerted torque on the generator’s shaft. The performance of our modeling and control approach is validated via numerical simulations.",

Apart from the cyclo-passivity properties, this turns out to be intimately related to the interconnection topology of the system. A prime source of motivation for energy conversion is thermodynamics, in particular the Carnot-Clausius heat engine theory about conversion of thermal into mechanical energy. This classical theory is extended to general port-Hamiltonian systems satisfying structural conditions on their topology. In particular, the operation of Carnot cycles is generalized. This is illustrated by the examples of a precursor to the Stirling engine and an electro-mechanical actuator. Finally, alternative energy conversion schemes for general port-Hamiltonian systems, such as energy-routers, are discussed from the same vantage point.",

The system is stabilized via a scattering passive feedback law. We formulate the wave equation in a port-Hamiltonian fashion and show that the system is semi-uniformly stable, which is a stability concept between exponential stability and strong stability. Hence, this also implies strong stability of the system. In particular, classical solutions are uniformly stable. This will be achieved by showing that the spectrum of the port-Hamiltonian operator is contained in the left half plane C− and the port-Hamiltonian operator generates a contraction semigroup. Moreover, we show that the spectrum consists of eigenvalues only and the port-Hamiltonian operator has a compact resolvent.",

We show how to derive the model starting from the Principle of Least Action and we rewrite it as the interconnection between two port- Hamiltonian systems: an infinite dimensional system and a finite dimensional one. Therefore, we propose a control law that allows to exponentially stabilize the origin of the closed- loop system. Further, we show how to explicitly compute, from the system and control parameters, the exponential decreasing rate of the system's norm along time. For a sake of conciseness, we only sketch the theoretical proofs. Finally, we provide some numerical simulations illustrating the closed-loop performances with different choices of the control parameters.",

      "abstract": "This paper presents a design framework of discrete-time regulators for linear, port-Hamiltonian, boundary control systems. The contribution is twofold. At first, a discrete-time approximation of the plant dynamics originally described by a linear PDE with boundary actuation is introduced. The discretisation is performed in time only. Thus, the “distributed nature” of the state is maintained. Such a system inherits the passivity of the original one and is well-posed, namely the “next” state always exists. The second result is the characterisation of discrete-time, linear controllers in the port-Hamiltonian form that render the closed-loop dynamics asymptotically stable. A numerical example illustrates the effectiveness of the proposed framework.",

      "abstract": "This paper deals with modelling and control of an endoscope actuated by Ionic Polymer Metal Composites (IPMC) patches. The endoscope is modelled by a nonlinear partial differential equation (PDE) capable to describe large deformations. The dynamics of the flexible structure and of the IPMC patches are in port-Hamiltonian form, with the actuators interconnected to the mechanical device in power-conserving way. Thus, the complete model is a port-Hamiltonian system in which a PDE with fixed boundary conditions is coupled with a set of ordinary differential equations. The control inputs are the voltages applied to the patches, and the feedback law is designed within the Interconnection and Damping Assignment Passivity-based Control (IDA-PBC) framework. The asymptotic stability of the closed-loop system is proved, and the effectiveness of the design procedure is illustrated by a numerical example.",

      "abstract": "Port-Hamiltonian theory is an established way to describe nonlinear physical systems widely used in various fields such as robotics, energy management, and mechanical engineering. This has led to considerable research interest in the control of Port-Hamiltonian systems, resulting in numerous model-based control techniques. However, the performance and stability of the closed-loop typically depend on the quality of the PH model, which is often difficult to obtain using first principles. We propose a Gaussian Processes (GP) based control approach for Port-Hamiltonian systems (GPC-PHS) by leveraging gathered data. The Bayesian characteristics of GPs enable the creation of a distribution encompassing all potential Hamiltonians instead of providing a singular point estimate. Using this uncertainty quantification, the proposed approach takes advantage of passivity-based robust control with interconnection and damping assignment to establish probabilistic stability guarantees.",

      "abstract": "Data-driven approaches achieve remarkable results for the modeling of complex dynamics based on collected data. However, these models often neglect basic physical principles which determine the behavior of any real-world system. This omission is unfavorable in two ways: The models are not as data-efficient as they could be by incorporating physical prior knowledge, and the model itself might not be physically correct. We propose Gaussian Process Port-Hamiltonian systems (GPPHS) as a physics-informed Bayesian learning approach with uncertainty quantification. The Bayesian nature of GP-PHS uses collected data to form a distribution over all possible Hamiltonians instead of a single point estimate. Due to the underlying physics model, a GP-PHS generates passive systems with respect to designated inputs and outputs. Further, the proposed approach preserves the compositional nature of Port-Hamiltonian systems.",

      "abstract": "The energy Casimir method is an effective controller design approach to stabilize port-Hamiltonian systems at a desired equilibrium. However, its application relies on the availability of suitable Casimir and Lyapunov functions, whose computation are generally intractable. In this paper, we propose a neural network-based framework to learn these functions. We show how to achieve equilibrium assignment by adding suitable regularization terms in the training cost. We also propose a parameterization of Casimir functions for reducing the training complexity. Moreover, the distance between the equilibrium of the learned Lyapunov function and the desired equilibrium is analyzed, which indicates that for small suboptimality gaps, the distance decreases linearly with respect to the training loss. Our methods are backed up by simulations on a pendulum system.",

      "abstract": "This paper presents a framework for physics-informed energy-based neural network (NN) design to learn models of interconnected systems under the port-Hamiltonian (pH) formalism. In particular, this paper focuses on mechanical systems and incorporates the physical knowledge of Lagrangians into the neural networks to facilitate learning of equations of motion from the data. Moreover, the transformation from the Lagrangian mechanics to the Hamiltonian mechanics is incorporated into the NN architecture and learned from the data such that the learned model is compatible with the pH framework. Then, the structure of input-state-output pH models is imposed on the NN, which guarantees the dissipativity of the learned model. Furthermore, modeling interconnected systems is facilitated by the compositionality property of the pH systems. Additionally, the consistency between the Hamiltonian and Lagrangian is employed for the energy estimation to enable energy-based control. The proposed approach is shown to be computationally more efficient than the existing Lagrangian-based NN design approaches. Furthermore, the learned models with energy estimation are employed for energy-based model predictive control (MPC) design purpose. Experimental results using single (and double) inverted pendulum on carts show that the proposed learning-based approach can achieve an improved performance of model identification compared to the Lagrangian neural networks, accurate estimation of energies and strong control performance.",

      "abstract": "In this paper, we use elements of graph theory and port-Hamiltonian systems to develop a modular dynamic model describing the hydraulic behavior of 4th generation district heating networks. In contrast with earlier generation networks with a single or few heat sources and pumps, newer installations will prominently feature distributed heat generation units, bringing about a number of challenges for the control and stable operation of these systems, e.g., flow reversals and interactions among pumps controllers, which may lead to severe oscillations. We focus thus on flexible system setups with an arbitrary number of distributed heat sources and end-users interconnected through a meshed, multi-layer distribution network of pipes. Moreover, differently from related works on the topic, we incorporate dynamic models for the pumps in the system and explicitly account for the presence of pressure holding units. By inferring suitable (power-preserving) interconnection ports, we provide a number of claims about the passivity properties of the overall, interconnected system, which proves to be highly beneficial in the design of decentralized control schemes and stability analyses.",

The multiplier method is used to show exponential decay Me−αt with an expression for M and α in terms of the system parameters. The exponential stability of port-Hamiltonian systems has been studied in the literature, but previous results did not provide an explicit bound on the decay rate. This result is illustrated by the boundary stabilization of a Timoshenko beam.",

      "abstract": "In this paper, we combine the backstepping methodology and the port Hamiltonian framework to design a boundary full-state feedback controller that modifies the closed-loop in-domain damping of a Timoshenko beam. The beam under consideration is clamped in one end of its spatial domain and actuated at the opposite one. The port Hamiltonian formulation is used to derive several boundedly invertible transformations that map the original system into an exponentially stable closed-loop target system with additional in-domain damping terms. The proposed methodology allows the introduction of tuning parameters with clear physical interpretations for achievable closed-loop behavior. Simulations illustrate the performances of the controller.",

      "abstract": "This paper analyzes two synchronverters connected in parallel to a common capacitive-resistive load through resistive-inductive power lines. This system is conceptualized as a microgrid with two renewable energy sources controlled using the synchronverter algorithm. It is modeled as an interconnection of three port-Hamiltonian systems, and the dq-coordinates model is derived by averaging the frequencies. Applying the recent Leonov function theory, sufficient conditions to guarantee the global boundedness of the whole system’s trajectories are provided. This is necessary to reach the global synchronization of microgrids. Additionally, a numerical example illustrates the potential resonance behavior of the microgrid.",

      "abstract": "This study introduces a novel control oriented structure-preserving scheme for discretizing a class of multi-dimensional linear port-Hamiltonian systems, preserving their inherent structure while enabling the imposition of diverse combinations of boundary inputs, such as generalized velocities, displacements, and tractions. The proposed approach is grounded on the modified Linked Lagrange Multiplier method and the mixed Finite Element Method (FEM), where Dirichlet and Neumann boundary conditions are weakly enforced. Connections with other standard and mixed FEM approaches are also discussed. The proposed scheme is validated through comparisons with commercial software and simulations using a 2D elasticity model as a demonstrative example.",

      "abstract": "Systems of partial differential equations often admit different Hamiltonian representations, leading to different boundary variables that are either power or energy conjugate. It is shown that any linear infinite-dimensional Hamiltonian system can be transformed into one with constant symplectic matrix. Alternatively, any passive linear Hamiltonian system can be converted into one with constant energy storage matrix. The consideration of energy boundary variables points towards a new approach to control by interconnection. All this is illustrated on the example of the elastic rod.",

      "abstract": "Controlling large-scale cyber-physical systems necessitates optimal distributed policies, relying solely on local real-time data and limited communication with neighboring agents. However, finding optimal controllers remains challenging, even in seemingly simple scenarios. Parameterizing these policies using Neural Networks (NNs) can deliver good performance, but their sensitivity to small input changes can destabilize the closed-loop system. This paper addresses this issue for a network of nonlinear dissipative systems. Specifically, we leverage well-established port-Hamiltonian structures to characterize deep distributed control policies with closed-loop stability guarantees and a finite ${\\mathcal{L}}_{2}$ gain, regardless of specific NN parameters. This eliminates the need to constrain the parameters during optimization and enables training with standard methods like stochastic gradient descent. A numerical study on the consensus control of Kuramoto oscillators demonstrates the effectiveness of the proposed controllers.",

      "abstract": "In this paper are presented a novel modeling approach and a passivity-based control scheme to solve the output voltage regulation control problem of a class of Quasiresonant Converters. Instead of consider classical order reduction arguments, the proposed full order model recovers the Port-Controlled Hamiltonian structure naturally exhibited by the converters. This feature leads to the possibility to propose the implementation of a passive PI control scheme which has been widely recognized to achieve high performances while proving in a formal way its stability properties. In addition, the controller structure is complemented by the inclusion of a static map to use both the frequency and the duty-cycle of the square input signal as control input, guaranteeing a Zero Current Switching operation mode which drastically improves the efficiency of the circuit. The usefulness of the proposed model and control are validated in a numerical setting.",

      "abstract": "This paper proposes a novel nonsingular terminal sliding mode controller for mechanical systems based on passivity-based control. In the authors’ previous study, passivity-based sliding mode control is realized with kinetic potential energy shaping (KPES), which allows us to construct a wider class of energy-based Lyapunov function candidates. This paper extends KPES to deal with a special class of Lyapunov function candidates whose arguments depend nonlinearly on the momentum. Based on this extension, we propose a nonsingular terminal sliding mode controller that achieves finite time convergence of the closed-loop system with an energy-based Lyapunov function. Due to the passivity-based approach, the proposed controller guarantees Lyapunov stability of the closed-loop system even if the discontinuous control input is replaced with a continuous one to alleviate chattering. A numerical example demonstrates the effectiveness of the proposed method.",

The proposed control synthesis technique operates by transforming the cascaded open-loop system into a port-Hamiltonian closed-loop system via feedback and a change of coordinates. The closed-loop port-Hamiltonian structure is physically interpretable. To add robustness, sufficient conditions for input-to-state stability of the closed-loop system with respect to the disturbances are identified. The method is illustrated in an example.",

      "abstract": "We develop compositional learning algorithms for coupled dynamical systems, with a particular focus on electrical networks. While deep learning has proven effective at modeling complex relationships from data, compositional couplings between system components typically introduce algebraic constraints on state variables, posing challenges to many existing data-driven approaches to modeling dynamical systems. Towards developing deep learning models for constrained dynamical systems, we introduce neural port-Hamiltonian differential algebraic equations (N-PHDAEs), which use neural networks to parameterize unknown terms in both the differential and algebraic components of a port-Hamiltonian DAE. To train these models, we propose an algorithm that uses automatic differentiation to perform index reduction, automatically transforming the neural DAE into an equivalent system of neural ordinary differential equations (N-ODEs), for which established model inference and backpropagation methods exist. Experiments simulating the dynamics of nonlinear circuits exemplify the benefits of our approach: the proposed N-PHDAE model achieves an order of magnitude improvement in prediction accuracy and constraint satisfaction when compared to a baseline N-ODE over long prediction time horizons. We also validate the compositional capabilities of our approach through experiments on a simulated DC microgrid: we train individual N-PHDAE models for separate grid components, before coupling them to accurately predict the behavior of larger-scale networks.",

Port-Hamiltonian systems (PHS), in particular, are well-suited for interconnection and damping assignment passivity-based control (IDA-PBC) due to their structured, energy-centric modeling approach. However, current IDA-PBC faces two key challenges: (i) it requires precise system knowledge, which is often unavailable due to model uncertainties, and (ii) it is typically limited to set-point control. To address these limitations, we propose a data-driven tracking control approach based on a physics-informed model, namely Gaussian process port-Hamiltonian systems, along with the modified matching equation. By leveraging the Bayesian nature of the model, we establish probabilistic stability and passivity guarantees. A simulation demonstrates the effectiveness of our approach.",

      "abstract": "Port-Hamiltonian neural networks (pHNNs) are emerging as a powerful modeling tool that integrates physical laws with deep learning techniques. While most research has focused on modeling the entire dynamics of interconnected systems, the potential for identifying and modeling individual subsystems while operating as part of a larger system has been overlooked. This study addresses this gap by introducing a novel method for using pHNNs to identify such subsystems based solely on input-output measurements. By utilizing the inherent compositional property of the port-Hamiltonian systems, we developed an algorithm that learns the dynamics of individual subsystems, without requiring direct access to their internal states. On top of that, by choosing an output error (OE) model structure, we have been able to handle measurement noise effectively. The efficiency of the proposed approach is demonstrated through tests on interconnected systems, including multi-physics scenarios, highlighting its potential for identifying subsystem dynamics and facilitating their integration into new interconnected models.",

For a system that is exponentially stable, it is reasonable to expect the approximation to preserve this decay rate. Preservation of the decay rate is important for realistic simulations and also for reliable controller design. We show that a simple mixed finite element method conserves exponential stability for a class of boundary-damped systems that are port-Hamiltonian. The results are illustrated by LQ-optimal controller design for a wave equation with spatially varying physical parameters. The convergence and performance of the controllers obtained using this mixed finite element method are compared to those obtained using a standard finite-element method approximation, which does not preserve the stability margin.",

Unlike the classical Partitioned Finite Element Method (PFEM) approach, the proposed discretization method makes it possible to obtain an ordinary differential equation regardless of the boundary conditions, preventing the emergence of a differential-algebraic equation in the case of mixed boundary conditions. This novelty, recently validated for the wave and Timoshenko beam equations, is now extended to PDEs with a second-order differential operator. On the Schrödinger and Euler-Bernoulli equations, it is shown that the proposed numerical scheme can deal with a large type of boundary inputs and outputs.",

      "abstract": "The Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) is an advanced nonlinear control strategy founded on the passivity and stability principles of port-Hamiltonian (PH) systems. This approach provides a powerful tool for controlling underactuated nonlinear systems by assigning them a desired energetic structure, establishing a new equilibrium point and achieving asymptotic stability through energy dissipation. The main challenge in this context lies in solving complex, nonlinear Partial Differential Equations (PDEs) that arise from the desired energy shaping process. This challenge is often mitigated by identifying classes of systems for which these equations are solvable. To address these limitations, a Physics-Informed Neural Networks (PINNs) based approach for solving the nonlinear PDE related to the kinetic energy and the definition of a customized loss function is proposed. Furthermore, it is shown that, assuming the kinetic energy PDE is solved with minimal error, stabilization can be achieved through appropriate tuning of the damping matrix and by adopting a simple structure for the potential energy function, eliminating the need to solve the potential energy PDE. The proposed methodology is verified through numerical simulations.",

These field formulations are based on the Darwin-Ampére equation and yield different approximations of the full set of Maxwell's equations depending on the choice of additional equations. Various discrete EMQS formulations are analyzed using the port-Hamiltonian system framework. It is shown that only combinations of the Darwin-Ampere equation and the Maxwell continuity equation yield port-Hamiltonian differential-algebraic system of equations (pH-DAE) which implies their numerical stability, energy conservation related to a specific EMQS variant of the Hamiltonian and dissipativity results.",

      "abstract": "This paper presents an interconnection and damping assignment passivity-based controller (IDA-PBC) for Cascaded H-bridge Multilevel Inverter (CHMI). The main objective of this paper is to investigate the output voltage waveform regulation with low harmonic distortion. The circuit is modeled as a port-controlled Hamiltonian (PCH) system through average modeling. IDA-PBC is capable to regulate the voltage during various loading condition. The proposed control scheme is compared to the conventional double-loop PI controller and verified by detailed simulation analysis using MATLAB-Simulink software. Simulation results show that the proposed algorithm ensures fast response time and stability of the system during load change while maintaining low harmonic distortion.",

Using the dissipative Hamiltonian structural properties, the collection of PCH systems are combined to generate an augmented PCH system, with which a simultaneous stabilization controller is then designed. Based on the zero-state detectability, a more general result is also obtained for the simultaneous stabilization of the PCH systems. Finally, using the results obtained in this paper, the simultaneous stabilization of a collection of affine nonlinear systems is also investigated, and some useful corollaries are presented.",

We first use the LQG method to design two passive type controllers which are equivalent to the control of port Hamiltonian system by interconnection. One of these LQG type method permit us to define a LQG balanced realization by computing its LQG Grammians. Then we use the effort-constraint method to achieve a reduced order port Hamiltonian system and design a reduced order passive type LQG controller. Finally, the method is illustrated on a mass-spring system by numerical simulations of the closed loop system with the full order passive LQG controller and with its reduced order controller.",

      "abstract": "A new robust current control method of permanent magnet synchronous motor (PMSM) based on Port-controlled Hamiltonian (PCH) theory and disturbance observer is proposed in this paper. Firstly, the electromagnetic subsystem of PMSM is expressed as the PCH form. Then, the current tracking control is realized using the energy-shaping method of interconnection and damping assignment, and the stability in the equilibrium is proved. In addition, according to the parameter perturbation of the PMSM, a disturbance observer is designed to estimate the disturbance, which is used to the feedforward compensation control of the current loop. The simulation results show that the proposed control method has good current tracking performance and robustness.",

      "abstract": "This paper presents a new method to asymptotical stabilize the one-area Load Frequency Control system via the methods of Port-Hamiltonian system and cascade system. Due to the proposed method, the structural features of Load Frequency Control system have been deeply studied, that is, it can be represented as two cascade system. The asymptotical stability of one cascade system can be assured via the Integral Addition method for its structure is the same as the Port-Hamiltonian system, while the asymptotical stability of other cascade system can be assured by the Lyapunov function. Depending on the asymptotical stabilizations of the two cascade systems, a PID control law based on the views of PH system and cascade system is designed to asymptotical stabilize the Load Frequency Control system. Simulation results is given to show the effect of proposed method.",

In this paper the magnetic levitator model is synthetized using a Port Hamiltonian approach and with this model, an observed state gain feedback is tuned with a LQG technique. Then a SMC that used the observed state gain feedback in the sliding zone is developed, establishing the requirements for feedback stabilization. Results show that the system is able to stabilize the levitation sphere in a wider zone than the LQG control.",

Combined with modes charging and discharging modes, a port-controlled Hamiltonian mathematical model of the hybrid energy source system is established. By configuring the interconnection and damping matrices, an interconnection and damping assignment controller, incorporating the rule-based energy management strategy, is designed. When the load power demand changes, the designed controller can maintain the stability of the DC bus voltage and reasonably distribute the power between the battery and the supercapacitor. Experimental results verify the effectiveness of the proposed strategy.",

      "abstract": "Traditional grid-connected controllers often have complex structures, numerous control parameters, and limited stability, making them less suitable for practical applications. Therefore, it is crucial to design grid-connected controllers in a reasonable manner to enhance the grid-connected disturbance suppression capabilities of inverters. This paper begins by analyzing the pros and cons of traditional control methods, specifically focusing on the high-boost ratio Y-source inverter (DLVC-YSI-I) topology with DC link voltage clamping. Subsequently, the port-controlled Hamiltonian (PCH) model and energy-shaping control (ESC) method are employed to address the control problem of the improved Y-source grid-connected inverter from an energy perspective. By constructing a state average model based on the proposed topology's operating principle and converting the improved Y-source grid-connected inverter model into a PCH model using the state average method, an inverter grid-connected controller is designed based on ES theory. Finally, the proposed algorithm is validated on an experimental platform consisting of an impedance source inverter grid-connected system.",

      "abstract": "This paper addresses the passivity of continuous bioreactors around their non-zero equilibrium point by representing the system into a port-Hamiltonian system. In case of continuous bioreactors, the steady-state values of substrate(s) and biomass are not zero, thus passivity at shifted equilibrium point becomes interesting. A general representation of bioreactors is written in a form that allows to derive very simple conditions to prove their shifted passivity, using a quadratic energy function. In addition to that, the case of enforcing shifted passivity using feedback proportional control for general representation of bioreactors is also considered. Practical conditions are given for general single microbial reactions, and an example of anaerobic digestion of volatile fatty acids illustrates the multiple microbial reactions case.",

The proposed control strategy is based on the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) framework, which exploits the system’s passivity properties to design a controller that ensures global stability while shaping the closed-loop energy function. The converter is modeled using a port-Hamiltonian formulation, enabling the systematic development of the IDA-PBC scheme. This approach effectively transforms the trajectory tracking problem into a regulation problem, ensuring asymptotic stability and guaranteeing a wellposed energy function in the closed-loop system. Numerical simulations validate the proposed strategy, demonstrating that the sinusoidal current supplied by the PWM-CSC maintains a tracking error below $2 \\%$ and harmonic distortion levels below $3.5 \\%$ for both voltage and current waveforms. All simulations were performed in MATLAB/Simulink using the SimPowerSystems toolbox, version 2024b.",

Since continuous MMC state-space models naturally have time-periodic steady-state solutions, a first step towards the derivation of the controller is the formulation of an equivalent model characterized by constant steady-state solutions, obtained via a multi-frequency orthogonal coordinates transformation. For the design of the controller, the overall system is represented in an appropriate port-Hamiltonian formulation, which allows the derivation of the stabilizing control law using passivity-based arguments. The results are validated on a three-terminal simulation benchmark.",

      "abstract": "In this paper, our objective is to use notions of system energy to formulate closed-loop dc-dc converter controls that are nonlinear and satisfy passivity properties that guarantee stability. Port-Hamiltonian models are a particular form of models which can be used to describe the total energy in a converter, much like a Lyapunov function. In our approach, we first formulate a port-Hamiltonian model that represents the desired closed-loop dynamics we seek. However, the solution to this model is generally quite difficult for even the simplest of converters. To bypass this challenge, we offer a framework where a neural-network-based controller is trained to estimate the solution to this design problem. Essentially, our objective is to ensure that the energy dynamics of the dc-dc converter with a neural network as a controller closely match that of the target port-Hamiltonian model. This method circumvents the mathematical difficulties encountered when attempting to solve the closed-loop port-Hamiltonian model directly and gives a generalized framework. Our paper illustrates this approach and its versatile application towards boost, buck, buck-boost, and Ćuk converters.",

However, the increased complexity of CPS caused by interactions between components creates challenges for the implementation of model-based design. In this paper, we present a modeling framework for the model-based design toolchain which uses port-Hamiltonian systems (PHS) to model CPS components and interactions. In this framework, passivity-based control methods are used to design controllers and compose them through Dirac structures. We evaluate the modeling framework using an automotive control system and present simulation results to demonstrate the effectiveness of the framework.",

      "abstract": "This paper presents a control scheme for the secondary level voltage control in DC Microgrids consisting of parallel operated converters and Constant Power Loads (CPLs). CPLs might cause a destabilizing effect on the DC bus voltage. The proposed control law uses the Port-Hamiltonian modelling framework applied to the Line Regulating Converters (LRCs) and filters and compensates the deviations of the voltage from its nominal value. This controller uses the concept of energy shaping and passivity; the idea behind this concept is to shape the energy in such way that the resulting closed loop system is Port-Hamiltonian. It is shown that the resulting Port-Controlled Hamiltonian (PCH) systems can be interconnected and large signal stability for all possible operating points can be guaranteed. Simulation results on a Microgrid test system display the good performance and stability of the proposed control scheme.",

      "abstract": "This paper designs a novel collaborative control approach, including the longitudinal and lateral motion control, to guarantee the vehicle stability by the estimated vehicle states of electric vehicles. A nonlinear observer is developed to observe the lateral velocity and tire-road friction coefficient by a Dugoff's tire model. Moreover, a Lyapunov-based method is utilized to prove that the estimated errors converge to zero. The collaborative control is converted into a tracking problem by establishing a reference model. According to the estimated vehicle states and reference model, a passivity-based control strategy based on the port-Hamiltonian model is adopted to follow the referenced vehicle states and ensure the stable planar motions, and the asymptotic stability of the proposed controller is proved. In addition, a wheel torque distribution considering the transfer of vertical loads is designed to maximize the utilization of tire adhesive forces. Finally, simulation cases demonstrate the effectiveness of the designed nonlinear observer and controller.",

Firstly, a baseline feedback control is proposed utilizing the damping injection method. To estimate disturbances, then a novel exogenous disturbance observer is constructed, based on which a feedforward compensation control is developed. Next, a composite control law is proposed based on the feedforward compensation and the feedback control. For the Hamiltonian system, an asymptotic stability analysis is followed finally. The feasibility of the compensation control strategy is revealed by a numerical simulation example.",

Based on the recent formulation of Luenberger's approach in a two-degrees-of-freedom controller structure, we consider the dynamics of both plant and dynamic controller in linear pH form. The main differences compared to the standard linear case are (i) the expression of the invariant manifold in terms of co-energy variables and (ii) the stability proof via the definiteness of energy and dissipation matrices. To this end, the formulation of well-known LMI conditions for the stabilization of linear pH systems is adapted to the considered (dual) problem. The approach marks a preliminary step for the work on the nonlinear pH setting. Simulation and experimental results with a magnetic levitation device using only distance feedback illustrate the applicability of the approach.",

The presented method is especially designed for controlling impedance energy-preserving port-Hamiltonian systems. By combining the stabilization results of port-Hamiltonian systems and the theory of robust output regulation for exponentially stable systems, we design a simple finite-dimensional controller for an unstable system that together with output feedback achieves robust output regulation. The method is demonstrated on an example where we implement a robust regulating controller for the one-dimensional wave equation with boundary control and observation.",

It is clear that the cascade interconnection of power electronic converters may introduce large oscillation or risk instability due to the fact that power electronic circuits performing as loads have a constant power load (CPL) actions. This article presents the dc link voltage regulation of a boost converter supplied by a fuel cell/reformer engine feeding a CPL. The construction of the feedback controller is based on the new Hamiltonian function in sense of a proportional, integral and derivative terms (PID). It is certified through the design that the desired fixed point is (locally) asymptotically stable. The technique is authenticated via digital simulations and experimental test bench of a 2.5 kW fuel cell/reformer system.",

A port-controlled Hamiltonian form is used to guarantee the passivity property. In addition, different passivity-based control methods are applied to different DERs in a microgrid, where an energy storage system, wind turbine, and solar-based DERs are considered. Since all the operating DERs can guarantee the passivity property, the stable operation of the microgrid is guaranteed. The simulation results demonstrate that the proposed control method effectively manages the microgrid, ensuring stable operation.",

      "abstract": "The Port-Based system modeling is applied and becomes an attractive topic in the field of control engineering. Due to its energy based concept, it can model physical systems in an effective and systematic manner, e.g. Port-Controlled Hamiltonian approach. However different model structures can be obtained, if the system contains switching devices, e.g. voltage source converter. This paper presents two approaches for converter modeling and their effect on the system behavior, when the controller is designed by the IDA-PBC concept. The simulation results show that the responses of the closed loop system hardly depend on the structure of converter model, even the obtained controllers are different. Especially when the systems operate around the operating point.",

      "abstract": "By using cascode technique, a buck boost converter can provide higher step-up voltage than the conventional does at the same duty ratio. Because of having non-linear variable structure and a zero on the right half plane, the cascode buck-boost becomes a challenging topic for control engineering. In this paper, an energy-based model of the converter is created and a controller design method using port-Hamiltonian is proposed. The developed controller is suitable for the non-linear system with variable structure, since the simulation results show the remarkable achievement of the proposed controller in command tracking and disturbance rejection. In addition, it can effectively treat the non-minimum phases issue of the converter.",

The converter is a non-linear and non-minimum phase system with variable structure, which is an interesting topic in control engineering. The non-linear controller obtained using the port-Hamiltonian approach exhibits impressive performance. However, parasitic resistance in the inductor and other components brings steady state error in the output. To solve this issue, an outer loop with an integrator is added. The use of an FPAA makes it easier to implement the developed controller compared to using a microcontroller because the controller can be directly synthesized by connecting the analog blocks.",

The controller is developed using the Port-Hamiltonian framework, enabling the design of a state feedback control strategy that employs all system state variables as feedback inputs. This approach ensures high system stability and a fast dynamic response under varying operating conditions. Simulation results confirm that the proposed controller successfully converts a $\\mathbf{3 1 5 ~ V}$ peak, $\\mathbf{5 0}$ Hz AC input into a stable 800 V DC output. Additionally, under sudden load disturbances, the controller effectively regulates and maintains a steady DC output voltage, demonstrating robust performance and resilience.",

      "abstract": "It is well known that interactions between weakly damped LC input filters and constant power loads (CPL) can lead to instability. This paper deals, in particular, with this problem when several CPL are connected to the network through undamped LC filters. The second goal is the energy management. They are mainly achieved by controlling the energy flow between the network and a storage device. The latter is a super-capacitor connected to the network via two DC-DC converters. After Port controlled Hamiltonian (PCH) expression of the system dynamics, they are controlled using the passivity approach. A proof of stability of the controlled system is given. Robustness tests relative to parameters uncertainties are realized and simulation results confirm the validity the proposed approach. This approach has also the advantage of requiring the measurement of only two state variables.",

By combining rotor speed control and PCH passive control, the PMSG can quickly track the reference speed and DC-link voltage control can support power smoothly within the rated operating range of the wind turbine. To validate the effectiveness of the proposed method, a simulation was conducted by comparing it with traditional maximum power point tracking control.",

      "abstract": "In stand-alone power supply systems, due to fluctuations of electric energy generation and consumption, special devices are used for energy storage, most often batteries. In order to remove stress from batteries during sudden load change, it is advisable to use hybrid energy storage system (HESS), by adding a supercapacitor module to the battery. In this work, stand-alone power supply system with battery/supercapacitor HESS of active configuration are investigated in two modes with different structures – at the low load and at the high one. In the latter battery current should be limited due to improve the battery lifetime. Both HESS structures are represented as port-controlled Hamiltonian systems, and the synthesis of control systems is carried out using the IDA-PBC method. Given the nonlinearity of the system and its propensity to oscillations, the transition to the battery current limitation is accomplished by implementing the sliding mode of switching of the designed controllers. The conducted simulation studies in the Matlab/Simulink environment showed the workability and effectiveness of the proposed solution.",

We can alter the inverter model in three-phase abc coordinate to two-phase synchronous rotating dq coordinate for establishing port controlled Hamiltonian with dissipation (PCHD) model for this system. In view of this method, we can control the output energy of the system. Usually, we can use Single Chip Microcomputer or other kinds of computer with this algorithm for our design, this algorithm can be programmed with the computer language, such as C/C++ and assembly language, etc. Simulation results show that passivity-based control method can make this system possess the high-performance of robustness and dynamic.",

Thanks to the passivity property, global stability is guaranteed. The simulation results obtained using MATLAB/Simulink with the switching model are provided.",

      "abstract": "This paper presents a general control design for photovoltaic systems integrated with Direct–Current power grids by using an unidirectional boost converter. Passivity–based control (PBC) theory is used as a control technique since the dynamical model of the boost converter has an intrinsically port–Hamiltonian structure, where PBC theory is based upon, to design stable controllers via Lyapunov stability theory. To control the photovoltaic solar system, a current control mode is used, since photovoltaic cells are mathematically modelled as current sources, where the photo–current determined by the solar irradiance and the cell’s temperature. Proportional and proportional–integral passivity–based controllers are developed to operate the boost converter under current control mode to extract the maximum power available in the PV array. Simulation results are conducted via MATLAB/ODE–package software.",

The plant is described by port-controlled Hamiltonian (PCH) form. To perfect the implementation of the CPL application, an improved IDA-PBC is introduced based on the error between the desired equilibrium point and the state variable. Furthermore, the virtual damping assignment technique is addressed to tune the dynamic characteristic and an adaptive interconnection matrix is introduced for building the internal links in PCH models. Simulation and experimental results are given to show the effectiveness of the proposed approach.",

      "abstract": "With a high proportion of renewable energy connected to the power system, the power fluctuation problem of photovoltaic microgrid is becoming increasingly prominent. It is difficult for a single energy storage technology to meet the requirements of high power density and high energy density at the same time. Hybrid energy storage system (HESS) has become an effective solution to stabilize power fluctuation through the cooperative work of energy and power energy storage equipment. In this paper, a collaborative control strategy of \"system-level frequency division correction-equipment-level energy shaping\" is proposed. In the system level, Moby Dick optimization algorithm (BWO) is used to optimize the parameters of Variational Modal Decomposition (VMD) to achieve accurate frequency division of power signals, and in the equipment level, an energy shaping (ES) controller is designed based on port-controlled Hamiltonian (PCH) model. Through Matlab/Simulink simulation verification, the power deficit range of the system before suppression was -863.31W to 1182.25W. After adopting the control strategy proposed in this paper, the power deficit was suppressed to - 47.12W to 81.87W, reducing the fluctuation amplitude by 93.78%. Compared to traditional PI control, this strategy lowers DC bus voltage fluctuations by 45.3% to 65.8% and shortens suppression time by 24.7% to 33.3%. It significantly enhances the microgrid's stability and dynamic response performance under sudden power changes.",

      "abstract": "In this paper, a novel multi-input multi-output nonlinear model of proton exchange membrane fuel cells air supply subsystem under port-Hamiltonian framework is proposed-based on the segmentation of the cathode flow channel. The model consists of inlet valve, cathode flow channel, and back pressure valve to regulate the air supply. In this model, the valve openings are regarded to be inputs to the air-supply subsystem, and the valve orifices are modeled as a linear approximation from the characteristics curves of the solenoid valves. In addition, the developed model’s energy balance, dissipativity, and passivity properties are proved and discussed in details in this work. Furthermore, a passivity-based control action is designed to track the desired pressures trajectories in port-Hamiltonian framework with explicit stability analysis. Finally, the designed control action can minimize the tracking error of distributed pressures in the segments and also prove the effectiveness of the proposed model, as depicted with simulation results.",

      "abstract": "Starting from the classical structure of a three-phase voltage DC-AC converter whose basic controller is designed based on the PI-type control law, this article shows the structure of a DC-AC converter control system (CCS) based on the Port Controlled Hamiltonian (PCH) controller, along with the improvement of DC-AC CCS performance by means of machine learning (ML) strategy. Among these strategies, the most suitable for process control is reinforcement learning (RL), and the RL Twin-Delayed Deep Deterministic Policy Gradient (TD3) agent was chosen from the concrete implementations. The control structures and the synthesis of the PCH control law based on passivity theory are presented, and, in addition, the creation and training of an RL-TD3 agent is presented. Through numerical simulations it is proved the improvement in the DC-AC CCS performance in case of using the RL-TD3 agent in terms of the performance indicators of the control systems, of which we mention: response time, steady-state error, ripple, but also in terms of the quality of electricity according to the Total Harmonic Distortion (THD) analysis.",

The proposed controller guarantees globally exponentially stability for the system under closed-loop conditions via proportional control design. An averaging model of the buck-boost DC-DC converter is employed to represent the dynamics of the system via port-Hamiltonian (pH) structure. Simulation results show that a unique control law can be used to the charging or discharging battery process. MATLAB/SIMULINK software is employed to validate the proposed control methodology.",

      "abstract": "This paper addresses the voltage regulation problem on isolated three-phase microgrids via passivity-based control (PBC) with a proportional regulator under the abc reference frame. This reference frame is employed to design the proportional controllers to support voltage and frequency profiles on time-varying loads through a combination of small distributed energy resources and battery energy storage systems. The proposed approach avoids using frequency measurements and reduces the complexity of the control problem. PBC theory exploits natural port-Hamiltonian formulations of the power electronic converters to design controllers, guaranteeing stability for closed-loop operation. Two passivity-based proportional controllers are proposed and compared with conventional proportional actions reported in specialized literature. Simulation results show the effectiveness and robustness of the proposed approach to fulfill the control tasks.",

The controller is applicable for conventional generation with synchronous machines as well as for power electronics interfaced sources and it is robust against power fluctuations from uncontrollable loads or volatile regenerative sources. The price-based formulation allows additional requirements such as active power sharing to be met. The capability and effectiveness of our procedure is demonstrated by means of an 18-node exemplary grid.",

      "abstract": "For distributed haptic cooperation systems, this paper develops a framework for virtual environments such that the design of the coordinating controllers is decoupled from the network topology and the communication issues. The discrete-time n-port passivity of the shared virtual object (SVO) is presented when n SVO copies are distributed on an undirected and connected communication topology with unreliable data transmission. Wave nodes as passive network elements can be implemented on multilateral wave-based communication architecture to passively distribute power across the network. In this note, the wave node scheme introduced in [16] is employed to construct a passive wave-based network architecture in order to passively interconnect multiple discrete-time port-Hamiltonian local SVO copies alongside their coordinating controllers. The performance analysis shows that the proposed network architecture: (i) possesses n-port passivity over a network with time-varying delay and packet-loss; (ii) is lossless when subjected to communications with no time delay; and (iii) offers less dissipation comparing to the network structures built based on the node scheme proposed in [18]. Simulations in which a VO is shared among four peers across a network with constant and varying time-delay validate the analysis.",

      "abstract": "The DC-DC boost converter has a non-linear characteristic and the control-to-output transfer function of the linearised model exhibits a non-minimum phase system with a right-half-plane (RHP) zero. The consequence of this zero is a sluggish response of the converter and it’s difficult to design a controller that is robust against load variation. In this work, we present a non-linear passivity-based control (PBC) algorithm to regulate the output voltage of the DC-DC boost converter. This controller works on the principle of an ‘energy shaping plus damping injection’, which is obtained from non-linear dynamical feedback. The non-linear DC-DC boost converter is modeled by using Euler-Lagrange, Port-controlled Hamiltonian and Brayton-Moser equations. These different classical mechanics based controller’s design and their simulation results of input-output variables are compared under reference step changes and load perturbations in MATLAB/Simulink.",

To overcome several difficulties in using FCs as unique energy sources, the association of supercapacitor (SC) as power sources is proposed. A recent approach of passivity-based control (PBC) is the interconnection and damping assignment (IDA-PBC) which is a very useful technique to control systems assigning a desired port-controlled Hamiltonian (PCH) structure to the closed-loop. This paper constitutes a first attempt to use energy principles and PBC to regulate hybrid sources for embarked electric energy system",

      "abstract": "Moving toward more electric aircraft (MEA) concept, electrification of modern aircraft will consist of a large amount of constant power load (CPL), which giving tough stability problems and research opportunities. In such an application, on-board dc power system may have a time-varying system structure and operation pattern due to the flexibility of the distributed loads. This feature poses challenges for system stability and increases the difficulty of the stability analysis. To solve this problem, an interconnection and damping assignment (IDA) passivity-based controller (PBC) is proposed in this paper. Particularly, an adaptive interconnection matrix is designed for building the internal links in port-controlled Hamiltonian (PCH) system, and the virtual damping assignment technique is addressed to tune the dynamic characteristic. To meet all the electricity supply needs, the design procedures were introduced for determining the control law in both boost converter and buck converter cases. Simulation and experimental results are performed to confirm the proposed control algorithm. Results show that the proposed control approach ensures the stability and the fast response of the system in different cases when the CPL changes.",

To ensure the system stability, the Passivity-Based Controller (PBC) called Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) is addressed in this paper. The stability of the cascaded systems are proved via using the Hamiltonian function (storage function) as the Lyapunov candidate function. Especially the dynamic and the potential instability caused by the LC filter are regulated by rendering the LC filter into the Hamiltonian framework of the controlled subsystem. The performance of the proposed approach are illustrated in simulation and experiment.",

      "abstract": "This paper proposes the stabilization method of the DC microgrid, which includes multiple cascaded DC/DC power converters and LC filters. Stability is achieved by building a modified Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) based on port-controlled Hamiltonian modeling at the subsystem level. Firstly, the general design process of the proposed control strategy and its large-signal stability proof are introduced, and then the stability of the whole microgrid is proved. Secondly, a design example of the source subsystem controller is given. Finally, the modified IDA-PBC is applied to the basic unit of a DC microgrid. The experimental results and Hardware-in-the-loop results indicate the effectiveness of the proposed strategy.",

      "abstract": "This paper proposes a rigorous modeling and control strategy based on the port-Hamiltonian ($\\mathbf{p H}$) framework applied to a bidirectional DC-DC extended SEPIC converter intended for Vehicle-to-Everything (V2X) applications. Unlike commonly used idealized averaged models, the proposed formulation explicitly incorporates dissipative effects arising from parasitic resistances of inductors, equivalent series resistances of capacitors, and switching component losses. The system is described using canonical energy variables, ensuring intrinsic consistency of power exchanges and dissipation. A Lyapunov based stability analysis is carried out, and an Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) law is developed to guaranty output voltage regulation under bidirectional power flow operation. The desired equilibrium point is analytically computed from the dissipative steady-state equations, avoiding the use of iterative numerical methods. MATLAB/Simulink simulation results confirm the theoretical validity of the proposed approach and demonstrate robust regulation under load variations.",

Attention is given for non-linear systems which can be modeled as a port-Hamiltonian systems with affine state-dependent interconnection and damping matrices, and quadratic state-dependent Hamiltonian function. In particular, an LMI based characterization of the energy balance equation is achieved. Moreover, an hyper-rectangle is established on the state space domain, attempting to maximize the domain of attraction iteratively. The proposed method is applied to the third order Lotka Volterra food chain system, with good results on the convergence to steady state at the origin.",

      "abstract": "The advancement of power electronics field today has allowed us to generate new technologies in various areas such as renewable energies, energy storage systems with batteries, electric chargers, electric vehicle traction systems, and more. New technologies are increasingly demanding in terms of accuracy of system variables; for this, advanced control methods are applied, and this requires a model that correctly represents the operation of the system. The models of power converters are not trivial; therefore, this paper proposes to model a ThreeLevel Flying Capacitor Buck DC-DC Converter using the bond graph technique, which is a multiphysics modeling tool based on the electrical domain that will facilitate the comprehensive modeling of the system. In addition, the obtained model from the bond graph approach can be directly linked with a Port Hamiltonian System, to obtain a physical representation of the system and based on the conservation of energy. Moreover, results are presented with a proposed non-linear closed-loop control model decoupling the voltage and current dynamics of the multilevel converter. The obtained dynamic results demonstrate the good performance of the proposed modeling methodology.",

The dynamical system is viewed as energy-transformation device, which is particularly useful in studying complex nonlinear system. In this article, the PCH (port-controlled Hamiltonian) speed control model of PMSM is established. The speed controller, satisfying the maximum output power control theory, is proposed using energy-shaping principle. The resulting scheme consists of a state feedback to which a load torque observer is added to estimate the unknown load torque. The stabilization analysis of equilibrium is presented as well. Simulation results show that the control strategy proposed in this paper gives satisfactory performance both at steady state and during transients.",

Using interconnection and damping assignment passivity-based control (IDA-PBC) methodology, assigning a desired port-controlled Hamiltonian (PCH) structure to the closed-loop PMSM system, speed controllers are designed when the load torque is known and unknown, respectively. The stability of the desired equilibrium point satisfying the maximum output power control rule is also analysed. The speed controller of PMSM is implemented based on pulse-width modulation (PWM) control principle. By controlling the duty ratio of every inverter switch, PWM voltages satisfying the speed regulation requirement are provided to the three-phase stator windings of PMSM. Simulation results show the system has good dynamic and steady-state performances.",

Based on this model, a differentiable, force-torque sensing-independent, n-DoF passivity condition is derived, valid for time-varying references. An impedance fidelity metric is also defined from step-response power in free motion, capturing dynamic decoupling. The proposed metrics are validated in Gazebo simulations with a six-DoF manipulator and a quadruped leg. Results demonstrate the suitability of the PH framework for standardized impedance control benchmarking.",

The proposed approach constructs a quadratic error Hamiltonian directly in the physical coordinates, without any input or state transformations. By maintaining the geometric interconnection between the pose and velocity dynamics, the closed-loop system preserves the canonical PH structure in which dissipation is injected only through the velocity error channels. A closed-form control law is derived, consisting of a reference-side feedforward term and energy-consistent damping and stiffness injections, optionally complemented by a port-based PI correction to enhance robustness. The resulting error-PH system satisfies a passivity-based energy balance, and asymptotic convergence of both position and velocity errors is established via LaSalle’s invariance principle. Simulation studies on a 3-DOF USV model verify the effectiveness of the proposed controller in improving tracking accuracy and transient response while preserving physical consistency.",

A PCH model of induction motor is established. The induction motor and controller are interconnected, and desired closed-loop PCH system structure is obtained by the feedback control. The desired closed-loop Hamiltonian function is given. The controller and load torque observer are designed. The equilibrium stability of the closed-loop system is also verified. Using SVPWM signal transformation method, speed regulation of induction motor is implemented by controlling the duty ratio of every converter switch. The simulation results show the system has good load disturbances attenuation and good speed tracking performances.",

Structure preserving feedback of controlled conservative contact systems involves to determine the existence of closed-loop invariant Legendre submanifolds. General results characterizing these submanifolds are presented. For contact systems arising from the modelling of thermodynamic processes by using pseudo port-controlled Hamiltonian formulation a series of particular results, that permits to constructively design the invariant submanifold and relate them with the stability of the system, are presented. Furthermore, the closed-loop system may again be restricted to some invariant Legendre submanifold and the control reduced to a state-feedback control. A heat transmission example is used to illustrate the approach.",

However, ensuring the reliability and stability of these power grids is critical, and several control strategies have been developed to achieve these goals. In this study, we have modeled the decentralized behavior of microgrids using the port-Hamiltonian formulation and a PI controller to control the inverter voltage and output power. To demonstrate the effectiveness of our control method, we have conducted simulations that consider both maximum and worst-case system fluctuations.",

The idea is to supply such lights with clean electricity and isolated from the network. To answer this problem, one solution consists on the association of photovoltaic (PV) panel and battery. Battery can store energy from PV panel during the day and give it back during the night. First, the system model is presented then Port-Controlled Hamiltonian (PCH) form is written. This form allows to exhibit system characteristics and to simplify the stability proof. Then the control law is deduced using passivity theory and simulation results are shown. Contrary to PI or hysteresis control usually applied for these systems, here no sensor device is used for the control.",

A simple identifiability condition, is derived by transforming the port-Hamiltonian systems to the observable canonical form. Indeed, the observable canonical form, gives the possibility to represent the transfer function in a simplified form, similar to ARMAX models, used in identification. In order to test the identifiability of Port-Controlled Hamiltonian systems, a test was realized in the case of a LC circuit.",

More focus is put on chemical reaction network theory and its inclusion in the formulation to achieve synchronization between concentration space and reaction space. It is made clear that Gibbs free energy is an apt Hamiltonian function for such cases. The same concept is applied on a basic enzyme reaction. The Bond Graph models related to Hamiltonian formulation for both types of reactions are given in order to show its ability of pictorial representation and intuitive solution.",

Three case scenarios which include a healthy person, a sedated patient, and a spontaneously breathing patient are used to demonstrate the application of this model. The proposed model is sufficiently detailed enough to reproduce human respiratory responses to be applied in different representations of positive pressure while still maintaining low computational costs. The simulated results obtained are comparable to those in literature. The presented formulation of the Port Hamiltonian lumped parameter model can be applied in the design of robust controllers for Mechanical ventilators' patient dynamics.",

The proposed approach combines the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) method with droop control to control active and reactive power-sharing, as well as voltage magnitude and frequency. A port-controlled Hamiltonian model is developed to synthesize the control laws ensuring local stability at the microgrid’s equilibrium point. In comparison to previous IDA-PBC approaches presented in the literature, the approach proposed in this paper integrates droop control to improve dynamic performance and enable effective load sharing among distributed generation units. The performance of the proposed approach is evaluated using MATLAB/Simulink simulations on an islanded microgrid consisting of two sources and a constant impedance load. The obtained results demonstrate accurate active and reactive power-sharing, as well as efficient voltage control under disturbances.",

Both grid and controller are modeled as a port-Hamiltonian system, where the grid model consists of differential as well as algebraic equations. Simulations show that the resulting controller asymptotically stabilizes the frequency while maintaining minimum overall generation costs in steady state and being robust in terms of clock drifts and uncontrollable loads. Moreover, it is shown that active power sharing can be achieved by an appropriate choice of the cost function.",

      "abstract": "This paper presents a robust control strategy for enhancing the large-signal stability of DC microgrids with interconnected multi-segment converters. An improved Lyapunov-Hamiltonian Control Law (LHCL) is proposed to regulate the dynamic behavior of interleaved Boost/Buck converters supplied by fuel cells. By exploiting port-Hamiltonian modeling and integrating Lyapunov-based damping, the controller dynamically adapts to varying load conditions, particularly under challenging constant power load (CPL) scenarios. The proposed method ensures global stability by shaping energy flow and minimizing oscillations through analytically derived damping terms. Experimental validation on a test bench equipped with a real-time dSPACE controller demonstrates the superior performance of the LHCL approach under both constant resistance and CPL disturbances. The results confirm the method’s effectiveness in maintaining voltage stability, achieving current balancing, and ensuring robust energy management in DC microgrid interconnections.",

The control design is based on port-Hamiltonian system theory, enabling dynamic energy management among sources while maintaining global system stability. A nonlinear control law is developed using damping-injection techniques to regulate the DC bus voltage, ensure optimal power sharing, and respect power and energy constraints of each component. The strategy allocates fast dynamics to the supercapacitor, medium response to the battery, and slow dynamics to the fuel cell, achieving efficient energy coordination. Experimental validation is performed using a dSPACE controlled test bench with real-time monitoring. Results confirm that the proposed method ensures fast transient response, smooth voltage regulation, and robust operation under sudden load variations.",

      "abstract": "Stabilization of underactuated systems is a challenging problem especially when external disturbance is applied and the actuators are limited. Interconnection and damping assignment passivity-based control (IDA-PBC) is an approach to regulate the systems represented by port Hamiltonian modeling such as underactuated robots while its application is restricted by some PDEs. In this paper, IDA-PBC is implemented on a spatial3-DOF underactuated cable driven manipulator. A robust term with respect to bounded matched disturbance is designed, non-negative tension in cables by appropriate desired potential energy is considered and stability of the system is ensured by a Lyapunov candidate. simulation results illustrate the effectiveness of the proposed controller.",

For the parameter estimation we exploited the Immersion and Invariance approach to achieve an automatic tuning for the designed PBC controller. The locally asymptotic stability of the closed loop system under PBC control with proposed parameter estimator is shown using Lyapunov theory. Simulations are carried out to test performance of proposed adaptive control method. Results illustrates that the estimator successfully estimates the uncertain parameters and the PBC utilizing this parameters stabilizes the closed loop system and preserve the performance of certainty equivalent controller.",

At first, the Hamiltonian energy function is constructed according to the system model. Then, the model of wind turbine is transformed into the port-controlled Hamiltonian (PCH) system. Next, the bounded passivity-based controller is designed based on passivity theorems. Finally, in order to illustrate the effectiveness of the bounded passivity-based control, the simulations are performed.",

What's more, when the loads will be not pure resistive load, the inverter further requires controller possess high-performance. This paper proposes a nonlinear control strategy for the inverter called Passivity-based Control. We can alter the inverter model in three-phase abc coordinate to two-phase synchronous rotating dq coordinate for establishing the Port Control Hamiltonian (PCHD) model for this system. We can control the distribution of energy in the system to achieve the control aim.

Combined with the nonlinearity and passivity of MMC, this paper proposes a passive sliding mode (Port-Controlled Hamiltonian with Dissipation-Sliding-Mode Control) (PCHD-SMC) control strategy under three working conditions: steady-state operation, active power abrupt change and grid-side voltage abrupt change. Firstly, the Euler-Lagrange (EL) model of the modular multilevel converter was constructed, and the generation mechanism of the internal circulation was analyzed. Secondly, the passivity of MMC is analyzed, and the passive controller based on the EL model is applied to the current inner loop control. Then, sliding mode control is introduced to solve the problem that passive control is too dependent on parameters, which increases the robustness of the system and realizes the suppression of the two-fold circulation component. Finally, a 23-level MMC inverter simulation model was built in MATLAB/Simulink to verify the effectiveness and reliability of the proposed strategy.",

Energy-shaping approach is the essence of passivity-based control. With the definition of generalized passive Hamiltonian system, the PCH structure of permanent magnet synchronous motor was given. By using the MTPA (maximum torque per ampere) control theory, the desired equilibrium was obtained. The nonlinear controller was designed by the way of energy shaping method. Finally the system's stability was analyzed by simulation. The controller has preferable robustness and fast response performance",

By combining the damping injection, the finite time disturbance observer (FTDO) and the coordinate transformation techniques together, the composite controller is developed. The novel idea is to design a coordinate transformation to address the mismatched disturbance estimation. By the Lyapunov function method, the system output asymptotically converges to zero in the presence of mismatched disturbance. An example of a permanent magnet synchronous motor with simulations shows the effectiveness of the method proposed.",

Firstly, a port-controlled Hamiltonian (PCH) model of Buck-Boost converter and its suitable state space averaging (SSA) model are established. Secondly, using the energy-shaping theory of interconnection and damping assignment passivity-based control (IDA-PBC) techniques, the feedback control theory of Buck-Boost converter is given. Then the desired equilibrium point of the system is obtained, and the stability of equilibrium point is analyzed. Finally the feedback controller is developed using energy-shaping theory for the SSA model of the PCH system. Furthermore, an integrator is added around the passive output preserving stability to avoid steady state errors induced by the presence of noise and modeling errors. Simulation results for the full system confirm the correctness and efficiency of the obtained controller.",

      "abstract": "The design of a non-linear controller for a three-phase front end converter used to connect renewable energy sources to the grid is presented in this paper. The objectives of this controller are the injection of all the generated power into the grid and the control of the reactive power exchanged with the power system. The system is represented through Park coordinates and port controlled Hamiltonian models. The controller is designed by interconnection and damping assignment (IDA), and feedback linearization (FL). It is demonstrated that for the particular case of selecting interconnection and damping matrixes, then coupling can be eliminated from the system model and therefore the controller designed using interconnection and damping assignment results the same as that using feedback linearization. The control strategy proposed in the present work is validated through simulation.",

      "abstract": "Low voltage ride-through (LVRT) mandates that wind turbines stay connected to the grid during voltage drops. To satisfy the LVRT criteria for permanent magnet direct-drive wind turbines, this paper proposes a control strategy involving an energy-dissipating circuit on the machine-side and reactive power compensation on the grid. The machine-side energy-dissipating circuit, known as the Braking Chopper (BC) circuit, is utilized, while grid-side reactive power compensation employs the Port-Controlled Hamiltonian Algorithm (PCH). When the grid voltage drops, the BC circuit absorbs excess power generated during the fault to maintain stability in the DC bus voltage, while the PCH provides reactive power compensation. Once the grid voltage returns to normal, the BC circuit is disconnected, and the PCH resumes normal grid-connected operation. Using Matlab/Simulink, a simulation model was constructed, and simulations were conducted. The results demonstrate that the control strategy proposed in this paper enables successful LVRT during symmetrical grid faults.",

      "abstract": "This paper introduces a novel control strategy for a voltage source inverter (VSI) within a microgrid environment, using the port-controlled Hamiltonian (PCH) system framework. This approach simplifies the management of dynamic performance and convergence challenges that arise during interactions between power sources and constant power loads in the microgrid. The strategy leverages the passivity properties of system components, which play a crucial role in ensuring overall microgrid stability. To validate the proposed control method, a 3-phase inverter is implemented and tested in a laboratory setting using a Micro-LabBox controller board on the dSPACE platform. The control algorithm is digitally executed, and its effectiveness is demonstrated through both MATLAB/Simulink simulations and experimental results. The control strategy exhibits excellent performance during highly dynamic power-load cycles, making it a valuable solution for microgrid applications.",

      "abstract": "Electromagnetic transient (EMT) simulation is of fundamental importance for the design and operation of modern power systems. The solution of EMT models relies on numerical integration methods whose performance depends on the structure, scale, and stiffness of the system models. In this paper, we develop a synchronous generator model that maintains the underlying physical structure. In particular, a synchronous generator is represented as the interconnection of energy storage ports, dissipation ports, and external ports, leading to a canonical port-Hamiltonian system formulation. By exploiting the port-Hamiltonian structure, we introduce an energy-related invariant quantity for the developed model and construct a geometric numerical integrator based on the discrete gradient. This geometric numerical integrator can exactly maintain the energy-related invariant in the discrete-time solution. Numerical experiments verify the energy-preserving property of the proposed geometric. Comparative analysis with the Runge-Kutta method and the implicit trapezoidal method shows that, the energy-preserving geometric numerical integrator has better long-term numerical stability and accuracy especially at relatively large integration steps.",

In order to capture accurately the inherent characteristics of the human body in lumped-parameter manners, the conventional linear Kelvin-Voigt models are replaced by the nonlinear Hunt-Crossley models. As an application of the contact dynamics, coupled stability of compliant robotic arm with impedance control is theoretically analyzed from energetic viewpoints. Experiments are done to verify the massage stability. The proposed contact dynamics evidently has great potential on performance improvement of robot massage, which will be our research subject.",

      "abstract": "In this paper, we address the problem of stabilisation of robots subject to nonholonommic constraints and external disturbances using port-Hamiltonian theory and smooth time-invariant control laws. This should be contrasted with the commonly used switched or time-varying laws. We propose a control design that provides asymptotic stability of an manifold (also called relative equilibria)-due to the Brockett condition this is the only type of stabilisation possible using smooth time-invariant control laws. The equilibrium manifold can be shaped to certain extent to satisfy specific control objectives. The proposed control law also incorporates integral action, and thus the closed-loop system is robust to unknown constant disturbances. A key step in the proposed design is a change of coordinates not only in the momentum, but also in the position vector, which differs from coordinate transformations previously proposed in the literature for the control of nonholonomic systems. The theoretical properties of the control law are verified via numerical simulation based on a robotic ground vehicle model with differential traction wheels and non co-axial centre of mass and point of contact.",

We develop an energy monitoring control system that observes energy flows among the different subsystems involved in pHRC, shaping them to improve human safety according to selected metrics. Port-Hamiltonian formalisms are used to model each sub-system and their interconnection. An energy-based compliance controller that enhances safety by adapting the robot behavior is proposed and validated through extensive simulations.",

      "abstract": "In this paper we consider the problem in which the human commands the overall behavior of a robot team while the robots are controlled to comply with formation constraints. Such human-robot team interaction is challenging in terms of system complexity and control synthesis. Port-Hamiltonian framework is suitable for modeling the interconnected systems. In this paper we model the robotic team, cooperatively manipulating an object, as a constrained port-Hamiltonian system. Furthermore, we propose a passivity-based control approach in the port-Hamiltonian framework for the cooperative manipulation system guided by the human. The control mechanism is based on the energy shaping for achieving a desired behavior of the formation and its preservation. An energy tank in the cascade is introduced to guarantee passivity of the system commanded by the human and safe interaction with humans in the robot environment. We validate the proposed approach with simulation and experiments.",

      "abstract": "In this work, we show how the interactive behavior of an aerial robot can be modeled and controlled effectively and elegantly in the port-Hamiltonian framework. We present an observer-based wrench/impedance controller for a fully-actuated hexarotor. The analysis and control are performed in a geometrically consistent manner on the configuration manifold of the special Euclidean group SE (3) such that the UAV’s nonlinear geometric structure is exploited. The controller uses a wrench observer to estimate the interaction wrench without the use of a force/torque sensor. Moreover, the concept of energy tanks is used to guarantee the system’s overall contact stability to arbitrary passive environments. The reliability and robustness of the proposed approach is validated through simulation and experiment.",

Addition of control actions is requested to generate additional gaits and robustify the existing one. This paper designs an interconnection and damping assignment passivity-based control, rooted within the port-Hamiltonian framework, to generate further gaits with respect to state-of-the-art methodologies, enlarge the basin of attraction of existing gaits, and further robustify the system against controller discretization and parametric uncertainties. The performance of the proposed algorithm is validated through numerical simulations and comparison with existing passivity-based techniques.",

We propose a port-Hamiltonian description of the multi-robot system to exploit universal physical constraints in interconnected systems and achieve closed-loop stability. We represent a multi-robot control policy using an architecture that combines self-attention mechanisms and neural ordinary differential equations. The former handles time-varying communication in the robot team, while the latter respects the continuous-time robot dynamics. Our representation is distributed by construction, enabling the learned control policies to be deployed in robot teams of different sizes. We demonstrate that LEMURS can learn interactions and cooperative behaviors from demonstrations of multi-agent navigation and flocking tasks.",

      "abstract": "In this article, we investigate the model based position control of soft hydraulic actuators arranged in an an-tagonistic pair. A dynamical model of the system is constructed by employing the port-Hamiltonian formulation. A control algorithm is designed with an energy shaping approach, which accounts for the pressure dynamics of the fluid. A nonlinear observer is included to compensate the effect of unknown external forces. Simulations demonstrate the effectiveness of the proposed approach, and experiments achieve positioning accuracy of 0.043 mm with a standard deviation of 0.033 mm in the presence of constant external forces up to 1 N.",

      "abstract": "Navigating in human-filled public spaces is a critical challenge for deploying autonomous robots in real-world environments. This paper introduces NaviDIFF, a novel Hamiltonian-constrained socially-aware navigation framework designed to address the complexities of human-robot interaction and socially-aware path planning. NaviDIFF integrates a port-Hamiltonian framework to model dynamic physical interactions and a diffusion model to manage uncertainty in human-robot cooperation. The framework leverages a spatial-temporal transformer to capture social and temporal dependencies, enabling more accurate spatial-temporal environmental dynamics understanding and port-Hamiltonian physical interactive process construction. Additionally, reinforcement learning from human feedback is employed to fine-tune robot policies, ensuring adaptation to human preferences and social norms. Extensive experiments demonstrate that NaviDIFF outperforms state-of-the-art methods in social navigation tasks, offering improved stability, efficiency, and adaptability11The experimental videos and additional information about this work can be found at: https://sites.google.com/view/NaviDIFF.",

This energy control approach is chosen for its proprieties that allow the synthesis of robust control laws that guarantee the whole system stability. For this aim, the power system circuit and the classical droop control are firstly presented in Port Controlled Hamiltonian (PCH) form. Then voltage and droop controllers design methodology is detailed. The validity of this control configuration is verified through simulation results.",

Inductive transmission lines connect between these. The model of the SG and its prime mover includes a frequency droop loop that acts through the prime mover and its governor, with its own dynamics. The SG model takes into account the variation of the inductances with the rotor angle. We derive a mathematical model of the system that takes into account a simplified model of the damper windings and is a fifth order nonlinear system. We present sufficient conditions on the model’s parameters to insure local stability for the system. We strive to find sufficient conditions that are easy to verify. We use Lyapunov functions and the port-Hamiltonian representation.",

      "abstract": "Under the Internet of Things initiative, networks are designed to incorporate both sensing as well as switching/control action. The need for control action may arise in different physical domains. Bond graphs are a useful tool which provides modeling of multiple processes that simultaneously take place in different physical domains. The current work discusses the need to develop mathematical models of the dynamics associated with non-linear sensing and actuation processes that may take place in several physical domains. As many control solutions are designed in state space, Input-State-Output Port-Hamiltonian (ISO PHS) formulations are the best tool to describe the associated dynamics of the elements in a network. Non-linear switching action can be emulated using memristive devices. This contribution, therefore, focusses on translating bond graph representations accounting for energy exchange across different ports in a network, where the transduction processes take place in a multitude of physical domains. As an example, the ISO PHS of a bond graph of a memristive element embedded in a simple switch circuit is presented. The work is of general interest to the sensors community and has applications in the design of sensor networks.",

      "abstract": "This paper addresses the challenging energy management problem of a DC-microgrid elevator system using a coherent combination between port-Hamiltonian approach for physical system modeling, differential flatness for profiles generation and predictive control for taking into account constraints, optimization costs and reference profiles. The microgrid connected to a three-phase utility grid includes a mechanical part, a Salient Permanent Magnet Synchronous Machine (SPMSM), an energy storage unit, a super-capacitor, a solar panel (PV) generation unit as well as the corresponding converters to DC-links. We will concentrate here on the microgrid's mechanical part connected to the synchronous machine. More precisely, a constrained predictive control combined with differential flatness is employed for efficiently manage the dissipative energy. First, optimal profiles of both the stator currents and rotor speed are provided using flat trajectory generation. Next, a constrained Model Predictive Control (MPC) optimization problem is formulated in order to satisfy the a priori given profiles. Comparison and simulation results validate the benefits of the proposed approach.",

      "abstract": "This work investigates cooperative dual-arm manipulation between two ornithopters in the post-perching phase. Flapping wing aerial systems are lightweight platforms designed to imitate bird flight, suitable for environmental monitoring tasks. When interacting with their environment, these systems must be able to perch on a branch as an initial step, followed by adjusting their position to achieve the desired pose and workspace. This research explores the application of a Port-Hamiltonian-based control method for designing and analysing controllers in cooperative manipulation by two ornithopters during the post-perching phase. The connection of end effectors while holding an object adds complexity and constraints to the problem. To address this, an energy-based approach using Optimal Port-Hamiltonian control and Optimal Load Distribution (OLD) is employed to evenly distribute the load between the arms. The effectiveness and advantages of this method are demonstrated through the defined scenario in which an optimal control law is implemented to derive an efficient trajectory for cooperative manipulation while tracking the desired elliptical path.",

      "abstract": "The basic idea of the power-oriented graphs (POG) modeling technique is to use the power interaction between subsystems as basic concept for modeling. This approach is theoretically supported by the definition and the properties of the port-controlled Hamiltonian systems and allows the modeling of a wide variety of systems involving different energetic domains. Differently from the bond graphs technique, based on the same concept, the POG modeling technique solves explicitly the causality problem. By this way, the POG schemes are easily readable, close to the computer implementation and allow reliable simulations using every computer simulator. This paper introduces the properties of the POG technique and presents some examples related to automotive control systems",

The total bond graph, integrated by the electromechanical sub-model and the converter sub-model, spans mechanical, electrical and magnetic energy domains. Through the detailed bond graphs of sub-models and the total bond graph of the system, the corresponding port-controlled Hamiltonian (PCH) models for subsystems and the whole system are also extracted. Finally, the bond graph and the PCH model of DFWPS are validated by the simulations in 20sim.",

The main control objectives are to inject all the available power into the grid while controlling the reactive power exchanged with the power system. With this aim, the system is represented by its Port-Controlled Hamiltonian model and the controller is designed by interconnection and damping assignment. The proposed design allows a direct control of the DC link voltage dynamics while avoiding the use of derivatives in the implementation of control equations. The behaviour of the proposed control strategy is validated through simulations tests performed using a realistic converter model.",

Firstly, a Hamiltonian realization is proposed for the visual servoing system. We proposed an image based visual servo controller for a new binocular stereo vision model which can avoid estimating depth information. Secondly, in accordance with the Hamiltonian realization method the visual servoing system can be modeled as a port-controlled Hamiltonian (PCH) system. For the PCH system, the stability analysis is given. Finally, simulation results are presented to illustrate the performance of the proposed controller.",

A new double loop control of the D-PMSG is proposed with the outer speed loop controlled by a non-singular higher-order terminal sliding mode (NHTSM) controller to undertake maximum wind power point tracking (MPPT). In the inner current control loop is a passivity-based controller (PBC) designed to manage the three-phase PWM rectifier. Simulation results show that the controller design is effective and that the system exhibits satisfactory performance.",

An innovative Interconnection and Damping Assignment Passivity-based Controller (IDA-PBC) with multi-equilibrium states is proposed in this paper. The hybrid system is first modeled as a Port-controlled Hamiltonian (PCH) system by considering the PEMFC and the SC as external voltage signals. Moreover, the IDA-PBC is designed using the techniques of energy shaping and damping injection, and the multi-equilibrium states of the hybrid system in different operating modes are analyzed. Simulation studies are carried out in Matlab/Simulink software to validate the proposed control strategy. The results show that the proposed IDA-PBC with multi-equilibrium states optimally balances power flow distribution in the hybrid system and ensures the stability of the hybrid system in different operating modes.",

The proposed method is designed in the framework of port-controlled Hamiltonian system. The proposed method is made up of two parts, one thing is a feedfoward part and the other is a feedback part. The feedforward part is calculated from the model dynamics of VSI. The feedback part is designed to compensate for system uncertainty. The proposed method is verified with simulation and experiment. The simulation uses MATLAB/Simulink and PLECS, and the experiment uses hardware in the loop (HIL) with TI TMS320F28335 DSP. The simulation and experiment results compared with those using direct power control-sliding mode control (DPC-SMC) for the grid connected VSI. The proposed method gives less total harmonic distortions, faster transient response.",

Based on the model and passivity of MMC-UPQC, the passivity based controller is designed by injecting virtual damping in current inner loop, which can accelerate the convergence of error storage function and ensure the global stability of MMC-UPQC. To improve the disturbance rejection ability, the nonlinear active disturbance rejection control (ADRC) is employed in voltage outer loop to provide desired current for inner loop. A circulating current controller based on ADRC is designed, which can effectively reduce switching losses. Compared with PI control, the proposed control has advantages such as good dynamic and static performance and strong disturbance rejection ability. The simulation results of five-level MMC-UPQC in Matlab/simulink validate the feasibility of the proposed control strategy.",

      "abstract": "Nowadays distribution power systems are used in different applications such as aircraft, ships, submarines and hybrid electric vehicles. However, the interaction between individually designed power subsystems may cause instability. Moreover, in these applications, the constant power load (CPL) also poses challenges for system dynamic response and stability. Thus, the main objective is to stabilize the cascaded system supplying the CPL. An interconnection and damping assignment (IDA) passivity-based control (PBC) scheme for LC filter cascaded with buck converter supplying CPL is proposed. The plant is described by port-controlled Hamiltonian (PCH) form. Particularly, an adaptive interconnection matrix is developed to achieve internal links in PCH system. A modified IDA-PBC and its proof are presented to perfect the implementation for the CPL application. Simulation results are given to illustrate the effectiveness of the proposed approach.",

      "abstract": "This paper presents a Port-Hamiltonian based modelling and control approach for MVDC Shipboard Power Systems (SPSs). The Line Regulating Converters (LRCs) consist of parallel-connected submodules based on the single-phase Dual Active Bridge (DAB) topology. The load side converters (Point of Load (POL) converters) are tightly regulated buck converters, which exhibit Constant Power Load (CPL) behavior with destabilizing effect on the MVDC bus voltage. We apply here an Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) strategy to the MVDC SPS and evaluate its performance by simulation in MATLAB Simulink. The analyzed scenarios consider large disturbances such as load step up, submodule disconnection and LRC module disconnection. Furthermore, we prove that the entire MVDC is Port-Hamiltonian and therefore the system stability is guaranteed by the IDA - PBC.",

      "abstract": "This paper proposes a robust control approach for improving the power quality in three-phase standalone based micro-grids. The key developed idea is to increase the disturbance rejection ability of an Interconnection and Damping Assignment Passivity-Based Controller (IDA-PBC)by adding an integral action. Indeed, the classical IDA-PBC techniques suffer from their parametric dependency. Hence, the use of the proposed technique allows enhancing the load voltage quality either in nominal operating conditions or in presence of system uncertainties. The power system circuit is modeled as a Port-Controlled Hamiltonian (PCH)system. Then, the control design is detailed. The validity of the proposed control algorithm is verified using simulation studies, and its effectiveness is illustrated through a comparison analysis with a Proportional-Integral (PI)under various operating conditions.",

Compared to traditional current controllers, such as proportional-resonant controller, only one control parameter requires to be tuned in the proposed energy-shaping controller. Moreover, the proposed energy-shaping control can not only realize a quick tracking reponse, but also improve the steady-state performance of the injected grid current whether or not the grid voltage is distorted. Simulation and experimental results have validated the correctness and feasibility of the proposed scheme through a 1 kW grid-connected inverter system.",

The interconnection matrix is changed from the original antisymmetric matrix to the upper triangular matrix with zero corner elements, which simplifies the design process. What’s more, to enhance the stability of the system, the combination of classic control theory and modern control theory is proposed to design the damping parameters of the controller. The main idea is to ensure the inverter output impedance is passive. The relationship between the controller parameters and the external interaction stability is compared. The simulation results are carried out to validate the effectiveness and robustness of the proposed approach.",

However, the variation of the load connected on the output degrades the whole system operation. In this paper, by using port-Hamiltonian system concept, the Energy Shaping technique and damping injection is utilized to remove load fluctuation from controller design process. In addition, the feedback and feedforward controller can be designed simultaneously, and both are combined in the developed controller. Therefore, the feedback loop becomes robust, and the disturbance rejection is enhanced. The simulation and experimental results on a 24V, 30W DC-DC buck-boost converter show the remarkable achievement of the proposed controller in command tracking and disturbance rejection.",

      "abstract": "Controlling output voltage of the DC-DC Buck-Boost converter has been a challenging topic for many years, since its averaged dynamics is a non-minimum phase system with highly load variation. Several methods avoid this difficulty by controlling the voltage via the inductor current. This paper presents a nonlinear energy-based controller design approach, which can directly control the output voltage without internal current loop. Due to damping assignment technique, the damping of the closed-loop system can be determined, and the problem with load variation is solved. To verify the performance of the proposed approach, the controller is test with a simulation and with existing converter. The result confirms the achievement of the proposed controller.",

      "abstract": "The classic proper energy element in electric vehicle consists of batteries and fuel cell (FQ, which allow a relatively high autonomy, but they are with moderate power capability. On the other hand, the capacitors have high power capability they can only be considered for applications which require little energy. In term of specifics energy and power, supercapacitors are situated between accumulators and traditional capacitors. The hybridation of these sources with a power source as supercapacitor (SC) is proposed. A recent approach of passivity- based control (PBC) is the interconnection and damping assignment (IDA-PBC) which is a very useful technique to control systems assigning a desired port-controlled Hamiltonian (PCH) structure to the closed-loop.",

      "abstract": "In continuous processing plants, flexibility of the web is a source of vibrations and resonance amongst motor drives and thus reduces the product quality. Port-controlled Hamiltonian with dissipation (PCHD) modeling is considered to develop stabilization strategies with a physical interpretation and motivation of the control action. A web transport system is modeled as a PCHD system and the control action is defined to obtain asymptotically stable operating points for the controlled system by a passivity argument. The controller negative output feedback gain matrix is interpreted as the realization of virtual dampers added to the system. Structural analysis is used both for controller tuning and to define damping matrices to generate a master-slave-like structure.",

      "abstract": "This paper presents a high-performance nonlinear controller for Switched reluctance machine (SRM), acting as a speed regulation motor drive. We use a cascaded torque control structure for torque ripple minimization. In a cascaded control structure, accurate torque control requires inner current controller. Passivity-based control (PBC) approaches is proposed for current control purpose. By using the port-controlled Hamiltonian (PCH) systems theory, a full-order nonlinear controlled model is first developed. Then nonlinear passivity-based adaptive sliding mode control algorithm in the presence of external disturbances for the purpose of torque ripple reduction and characteristic improvement is presented. The proposed controller design is separated into the inner loop and the outer loop controller. In the inner loop, passivity-based control (PBC) is employed by using energy shaping techniques to produce the proper switching function. The outer loop control is employed by adaptive sliding controller to determine the appropriate Torque command. It can also overcome the inherent nonlinear characteristics of the system and make the whole system robust to uncertainties. The performance of the proposed controller algorithm has been demonstrated in simulation and also experimentally using a 4KW, four-phase, 8/6 pole SRM DSP-based drive system.",

      "abstract": "Passivity control of permanent magnet synchronous generator based on dual PWM converter can improve the system robustness. However, the DC bus voltage fluctuation still exists in the system because of the separated control for the generator-side converter and the grid-side converter. By introducing the grid-side dynamic power error into the passivity control, a novel coordinated passivity control scheme is proposed in this paper, in order to suppress the DC bus voltage fluctuation. The port controlled dissipative Hamiltonian system model of the permanent magnet synchronous generator system is established based on the dual PWM converter, furthermore, the original Hamiltonian energy function of the system is matched to the expected Hamiltonian energy function by the energy re-shaping. Moreover, the main factor of the DC bus voltage fluctuation is analyzed from the point of view of the expected Hamiltonian energy function. Compared with the traditional power feedforward control method, the system has no feedforward effect at the steady state, which proves the steady-state performance of the grid-side converter. The simulation results and the experimental results show that the proposed coordinated passivity control scheme can suppress the DC bus voltage fluctuation effectively.",

      "abstract": "There are numerous nonlinear components in grid-connected inverter systems, such as the output saturation nonlinearity of the grid-connected current control system and the dead-time nonlinearity existing in pulse width modulation (PWM) strategies. Traditional linear control strategies based on linearized models struggle to ensure the system operates with strong robustness and global stability. To address this issue, this paper proposes an energy shaping control strategy based on the Port-Controlled Hamiltonian (PCH) model, investigating the stability of the Grid-Connected Inverter (GCI) system from the perspective of energy control. Firstly, this strategy constructs the PCH model of the GCI system in the dq coordinate system. Then, by using the interconnection and damping assignment method, the energy shaping control law is derived. This law modifies the energy flow and energy dissipation modes of the closed-loop GCI system, thereby achieving the global asymptotic stability of the system. Simulation and experimental results demonstrate that the energy shaping control strategy is simple in structure and exhibits excellent transient performance. Meanwhile, it ensures the GCI system maintains global stability and strong robustness under weak grid conditions.",

      "abstract": "Port Hamiltonian systems are usually passive with respect to port variables that are power conjugate (eg: voltage and current, force and velocity) and this lead to energy shaping control methods. But systems with ‘dissipation obstacle’ cannot be controlled using these port variables and therefore we need to search for alternative passive maps. One option is within the Brayton Moser framework, where passivity is obtained by differentiating one of the port variables. This has led to power shaping methods for control, but the solutions (if exists) obtained impose constraints on the physical parameters of the system. In this paper, starting from the Brayton Moser framework we present a new passivity property with differentiation at both the port variables. Further using this new passive map, a PI like controller is proposed and presented using parallel RLC circuit and transmission line system with non zero boundary conditions as examples.",

The developed model takes into account various wireless communication aspects: such as a wireless path loss model, the characteristics of a wireless communication system, mac layer and network layer protocols, antenna design, latencies, buffer dynamics, acknowledgment rate and so on. In the OSI model of seven layers, the main layers responsible for the flow and control of traffic are the MAC layer and the Network layer. The model was developed based on the operation of these two layers. In this paper, we provide an experimental validation of the previously developed port-Hamiltonian model, in an indoor wireless network test bed. We demonstrate, that the analysis of the theoretical model agrees with the experimental data. This work is the first to provide an experimental demonstration of port-Hamiltonian models developed for wireless communication systems.",

Improvising on top of IDA-PBC which just focuses on stability, the memristive port-Hamiltonian control addresses performance concerns in the control task by providing a state-modulated damping term to IDA-PBC via a memristor element. The control way of implementing the memristive IDA-PBC first requires solving a set of Partial Differential Equations (PDEs) and then choosing a suitable memristance function for the system, out of which the former is a challenging math problem and the latter is a design problem. This paper employs reinforcement learning to learn the memristive IDA-PBC law and in the process, avoids the challenging task of solving PDEs, automates the design of the memristance function and also respects some physical system-level constraints which are not accounted for by the control way of solving IDA-PBC.",

      "abstract": "Tapped-inductor Buck (TI-Buck) converter has the advantage of appropriate duty cycle ratio during large voltage conversion ratio and is widely used in many cases. In order to improve the performance of TI-Buck converter, the control strategy of TI-Buck converter is presented in this paper based on the energy-shaping theory of interconnection and damping assignment passivity-based control (IDA-PBC) techniques. First, the Port-controlled Hamiltonian (PCH) model of TI-Buck converter is derived. With the model, the feedback controller of TI-Buck converter is given based on IDA-PBC techniques, and the stability of system equilibrium point is analyzed. Furthermore, an integrator is added in parallel with the passive output preserving stability to avoid steady state errors induced by the presence of noise and modeling errors. In order to verify the theory expectation, computer simulation is carried out. Simulation results show that the control scheme achieves a good regulation of output voltage and let the system have a quite strong robustness, and an enough control capability to the variability of input voltage and load.",

      "abstract": "This article studies the formation control problem of multiple uncrewed underwater vehicles (UUVs) under time-varying external disturbances. The formation system is composed of a leader UUV and two follower UUVs. A three-dimensional (3D) formation robust control protocol of multi-UUV is presented based on the interconnection and damping assignment passivity-based control (IDA-PBC) method and the disturbance observer (DOB) technique. Firstly, the original UUV models are transformed into the Port-Hamiltonian (PH) structure. Next, the desired closed-loop PH system of the UUVs is constructed. With the IDA-PBC method, the design procedure of the formation controller is equal to solving matching equations, making the controller design intuitive. The DOB technique is introduced to compensate for the external time-varying disturbances to improve the robustness of the formation system. Finally, simulation results show that the proposed method accomplishes satisfactory formation performance and demonstrates the effectiveness of the proposed control protocol.",

      "abstract": "Considering the influence of internal parameter perturbation on the speed regulating performance of permanent magnet synchronous direct drive generator, the mathematical model of Permanent Magnet Synchronous Direct Drive Generator (PMSG) is studied from Hamiltonian energy and robustness. First, the mathematical model of port-controlled Hamiltonian system (PCHD) of PMSG system is deduced. Secondly, based on the principle of energy forming, PCHD and the extended state observer (ESO) technology, a passive current controller based on ESO is designed. In order to simplify the control algorithm and reduce the electromagnetic torque ripple, the system disturbance term is observed and compensated by ESO based on the inverse hyperbolic sine function. The simulation results show that this control method can ensure the stable operation of the system. It has strong speed tracking capability, load capability and robustness as well as has small electromagnetic torque ripple.",

This class of infinite dimensional system is quite general, thus allowing the description of several physical phenomena, such as heat conduction, elasticity, electromagnetism and, of course, piezoelectricity. The key point is the generalization of the notion of finite dimensional Dirac structure in order to deal with an infinite dimensional space of power variables. In this way, the dynamics of the system results from the interconnection of a proper set of elements, each of them characterized by a particular energetic behavior, while the interaction with the environment is described in terms of mechanical and electrical boundary ports.",

In this modeling large deformation for beam is considered and consequently, high order curvature terms are not neglected. An adaptation method for applying large moments in the beam tip is developed using FEM. Port Hamiltonian interconnected system modeling is used to model the resulted configuration. The energy-based variable structure method is utilized to develop an interconnected controller with energy function associated with a set of Casimir functions relating to sliding surfaces. The energy function of the controller is chosen to make an attractive sliding surface for closed-loop system. Using this system, vibration of the nonlinear beam is stabilized in the desired shape of the beam.",

First, we focus on dynamics with endlink mass perturbation after the settling time. Second, we derive the exact and explicit structured singular value for manipulators by using structural properties of the dynamics. The derived structured singular value is nothing but the structured singular value of manipulators without control because the passivity based control preserves the Hamiltonian structure. Furthermore, based on the derived structured singular value, we quantitatively analyze the robust stability of robotic manipulators with the passivity based control",

Not only passivity but also Casimir functions are used in the modeling and control as a new structural property. First, we refer port-Hamiltonian systems and their properties. Second, we propose two stabilization methods, a new dynamic asymptotic stabilization method and a new partial stabilization method. Third, we give a new model of hydraulic arms using Casimir functions. Furthermore, the proposed two stabilization methods are applied to this model and finally, the validity of our methods are confirmed by not only numerical simulations but also experiments even thought the bulk modulus is not identified at all.",

The robot has a dexterous mechanism with similar distribution of actuators' capability and a pair of mechanical joint stops like human beings. The proposed motion planning method combines target dynamics together with port-controlled Hamiltonian (PCH) system theory resulting in an energy controller which not only takes the mechanical joint stops into account but also realizes torque compensation from a high-power actuator to a low-power actuator. Simulation and experimental results prove the proposed method can generate the golf swings with specified hitting speed and finish position for our specially designed robot.",

The algebraic constraints of the interconnected systems are represented by a geometric object, called Dirac structure. This provides a powerful way to describe the non-contact to contact transition and contact viscoelasticity, by using the concepts of energy flows and power preserving interconnections. Using the port based model, an Intrinsically Passive Controller (IPC) is used to control the internal forces. Simulation results validate the model and demonstrate the effectiveness of the port-based approach.",

In particular, we propose a switching-based state mapping and control algorithm between a rate-based passive controller, which addresses the workspace incompatibility between the master and slave systems, and a pose-based passive controller, which is required for precise operation. The overall control architecture provides the possibility of changing the scaling factor of the mapping online, while preserving the passivity of the complete system. In our formulation, we use the port-Hamiltonian framework, in which energetic considerations play a determinant role for passivity and, thereby stability of the overall system. Simulation and experimental results illustrating the effectiveness of the proposed algorithm are also presented.",

      "abstract": "Soft limb locomotion is a relatively new and challenging research field. However, soft limbs can not yet transition to practical application due to difficulties associated with control methods. Motivated by this research problem, in this paper, we investigate the performance of energy based control of underactuated soft limbed systems. We augment the previously reported energy shaping function for rigid bipeds with a new set of functions for the novel class of underactuated compass gait soft bipeds. We evaluate the controller performance and identify desired features and characteristics for better speed performance of such a biped. The proposed energy shaping functions are compared through controlled Lagrangian (CL) method for Euler-Lagrangian (EL) models and interconnection and damping assignment passivity-based control (IDA-PBC) methods for port-controlled Hamiltonian (PCH) models. Results for system stability, speed performance, and input torque profiles are compared. The IDA-PBC controllers are observed to produce better input torque and performance over the CL methods.The findings assist in extending and developing novel controllers to implement on soft limbed robots for practical control applications of soft multi-continuum limbed robots.",

It is based on graph theory and port-Hamiltonian systems, which allows a modular approach to the interconnection of rigid bodies with compliant actuators by means of kinematic pairs. This modularity allows a very simple and straight-forward change in a manipulator's actuator morphology. An example of a two degree of freedom planar manipulator shows that this modeling method is more suitable for modeling changes in actuator placement than traditional Euler-Lagrange models.",

      "abstract": "This paper presents a novel control approach, based on the interconnection and damping-assignment passivity-based control (IDA-PBC), to achieve stable and periodic walking for underactuated planar biped robots with one degree of underactuation. The system's physical structure is preserved by assigning a target port-Hamiltonian dynamics to the closed-loop system, which also ensures passivity. The control design ensures that the tracking error to the desired periodic gait converges exponentially to zero, and the convergence rate can be adjusted via gain tuning. Besides, through the hybrid zero dynamics, the stability of the full-order system can be retrieved from the stability of the orbit created in a lower-dimensional manifold. The proposed approach is the first example of a tracking controller based on the IDA-PBC applied to underactuated biped robots. Numerical simulations on a five-link planar biped robot with unactuated ankles validate the approach and show the performance of the closed-loop system.",

      "abstract": "In modern robotics, the manipulators are no longer isolated under fully controlled conditions but rather conceived to work in unconstrained environments. Under these operations, compliant control and passivity properties of the robot are of great importance, and thus the system’s energy function plays a crucial role in the control design. In this work, we propose a new design of cartesian impedance control for a flexible robot whose dynamics is represented within the port-Hamiltonian framework. To improve the performance of the system and maximize the capabilities of the robot, the robotic control system is enhanced with energy tanks that allow for temporarily non-passive operations, but ensure the passivity of the extended system. In addition, a secondary controller is designed using the port-Hamiltonian approach to cover the case of redundant robotic manipulators. The performance of the full control system is tested via simulations of the Kuka iiwa manipulator in closed loop with the proposed passivity-based controller. The results show a satisfactory performance of the control system for set-point regulation, external forces, time-varying reference trajectories, and parametric uncertainty.",

      "abstract": "This paper presents a secondary voltage control scheme for microgrids based on the port-Hamiltonian modeling framework. The proposed secondary controller compensates the deviations of voltage amplitudes from their nominal values using the concept of energy shaping, which is the essence of passivity-based control in port-Hamiltonian systems. We shape the energy function and define a new Hamiltonian function such that the new potential energy function has a strict local minimum at the desired equilibrium point. Next, a feedback control is designed such that the closed-loop system preserves the port-Hamiltonian structure. The Hamiltonian in this case is the sum of the plant and the controllers energy functions. The stability analysis is performed and sufficient conditions on the controller gains to achieve voltage regulation are derived. The effectiveness of the proposed control methodology is evaluated using simulation for a benchmark microgrid system.",

      "abstract": "The operation of converters interconnecting ac and dc grids in future inertia-free and weak networks poses significant challenges. Modular multilevel converters applying dual grid-forming controls are able to effectively synchronize to weak grids and control the dc voltage levels simultaneously. This paper proposes an enhanced dual grid-forming strategy based on an equivalent voltage representing the converter’s internal energy. The converter’s control variables have been redesigned in order to improve system stability margins while at the same time preserving the macroscopic port-Hamiltonian structure of the converter. The correct operation of the converter for different grid inertia constants has been proved through small-signal and time-domain simulations, including inertia-free conditions. Moreover, the system is stable at both very weak and strong grid conditions, with short circuit ratios from 1 to 30.",

In this paper, we propose a control law that not only enhances the transient stability but also makes the system to satisfy output synchronization. The key idea of this paper is that the power system can be realized as Port-Controlled Hamiltonian(PCH) model and the model automatically satisfies the passivity with respect to input and output relationship. Using the property, we can analyze the output synchronization by employing consensus algorithm. Through simulation results, we evaluate the synchronization analysis.",

Here, both the plant and the controller are modelled in PH form, in terms of their own Hamiltonians. However, obtaining an appropriate controller Hamiltonian is generally difficult. In this paper, we address this issue by using reinforcement learning (RL). Additionally due to the semi-supervised optimization nature of the RL algorithms, a performance criterion can be readily included in CbI. We demonstrate the usefulness of the proposed learning algorithm for stabilization of a manipulator arm.",

In order to provide global asymptotical stability of the closed loop control system in the sense of Lyapunov approach, VSC is modelled within port-Hamiltonian framework. Classical PBC techniques are insufficient to achieve zero steady state tracking error. To eliminate this errors caused by constant disturbances, integrator is inserted into to the proposed PBC. Furthermore, designed adaptive observer allows sensorless operation for the proposed method. Simulation results are presented to validate the proposed controller.",

The time-delay variation range is divided into two sub-intervals. By considering the probability distribution of the time-varying delay between the two sub-intervals and the knowledge of the delay variation range, a novel linear matrix inequality (LMI) based stability condition is derived by defining a Lyapunov-Krasovskii functional. It is illustrated with the help of a numerical example that as the probability of delay taking a small value increases, the upper delay bound increases.",

Onboard EV chargers (OBCs) have been installed on electric vehicles to charge batteries. The trend of increasing power rating and minimized sizing of OBCs, the improvement in stability and performance has been interesting. This paper demonstrates non-isolated EV onboard chargers with controller design based on Port-Hamiltonian control law to approach a robust control system and operate under wide operating range.

      "abstract": "In this paper, a decentralized PI passivity-based controller is applied to modular multilevel converters to ensure global stability of a multiterminal high-voltage direct current system. For the derivation of the controller, an appropriate model with constant steady-state solutions is obtained via a multifrequency orthogonal coordinates transformation. The control design is then completed using passivity arguments, and performance guarantees are established by a small-signal analysis. The obtained results are validated by means of detailed time-domain simulations both on a single-terminal and a four-terminal benchmarks.",

      "abstract": "This article proposes a modified interconnection and damping assignment passivity-based control (IDA-PBC) for dc/dc converter cascaded with an LC filter. The plant is modeled using the port-controlled Hamiltonian (PCH) form. The main objective is to stabilize the cascaded system in case the system supplies constant power load (CPL). To solve the instability issues caused by tightly controlled cascaded systems, the IDA-PBC based on an overall PCH model, including LC input filter and dc/dc converter, is established. Moreover, to ensure that the proposed IDA-PBC admits one unique solution, an adaptive interconnection matrix is designed to build the internal links in the PCH model. Furthermore, in order to improve the implementation on an onboard dc microgrid application with time-varying CPLs, a modified IDA-PBC algorithm is proposed based on the error between the state vector and the desired operating point, which might be variable. The closed-loop Hamiltonian function is chosen as the Lyapunov candidate function to guarantee that the system operates in a stable manner. The virtual damping assignment technique is addressed to tune the dynamic characteristic of the closed-loop system. Simulation and experimental results are carried out to illustrate the proposed method’s effectiveness.",

      "abstract": "The development of an advanced modular control strategy for distributed generation-based islanded MicroGrids (MGs) is proposed in this article. This control strategy aims at achieving robust performances and accurate load power sharing in spite of system architecture. This strategy is based on the interconnection and damping assignment passivity-based control (IDA-PBC), which provides sufficient conditions to ensure the system modularity and stability. The design methodology of the proposed method is declined into three important steps. The whole system is modeled using the port-controlled Hamiltonian (PCH) formalism, the Hamiltonian function is minimized to synthesize the corresponding control laws, and finally, the stability of the synthesized control laws is verified. In this work, the Hamiltonian function is augmented with an enhanced decoupled droop (E2D) control in order to guarantee the stability of the whole system and ensure accurate power sharing when multiple DG units are interconnected. The effectiveness and modularity of the proposed modular IDA-PBC control with the E2D technique are evaluated and compared with a recent control strategy using an inner proportional-integral control with a decoupled droop technique. Experimental results and discussions are provided under resistive–inductive and nonlinear loading conditions.",

      "abstract": "As the crucial interface of renewable energy integration, the stable operation of power converters under grid faults and external disturbances has become much more important. However, synchronization instability of grid-tied inverters has been found caused by the phase-locked loop (PLL) under some critical operating conditions, such as the grid voltage sag, current surge, and transmission line faults. Due to the strong nonlinearity, transient stability analysis of inverters with PLL becomes much more complicated under large-signal perturbations and weak grid conditions. In this article, the large-signal synchronization stability of grid-tied inverters is investigated from the energy perspective. Based on the structural resemblance between the PLL and synchronous generator, the energy function is constructed to establish a port-Hamiltonian model for the grid-tied inverter. For the nonlinear inverter system, an explicit Hamilton-based stability criterion is developed for grid-tied converters according to the concept of dissipativity and LaSalle’s theorem. Moreover, the analytical stability boundary is acquired based on the proposed stability criterion and attraction region estimation, covering both controller parameters and grid parameters. To verify the effectiveness of the proposed analysis approach, extensive simulation and experimental results are presented. Compared with the conventional large-signal methods, the proposed Hamilton-based approach has explicit physical meaning and high accuracy.",

      "abstract": "Maintaining bus voltage stability is a central challenge in dc microgrids (MGs). This article introduces a decentralized adaptive energy-shaping approach (DEC) that seamlessly merges constant voltage and droop mode (DM) controls, ensuring the comprehensive large-signal stability of the MG. Central to the DEC’s architecture is its stratification of the MG into autonomous distributed unit (DU) subsystems. Using a nonlinear observer, this strategy effectively recognizes the electrical interactions among individual DU subsystems, obviating auxiliary output current sensors. This structured approach breaks down the intricate stability challenges of the MG into more manageable sections. These sections are carefully designed to address estimated couplings and reinforce each DU subsystem’s resilience. The introduced stabilization method, inspired by the passivity-based port-controlled Hamiltonian (pcH) system theory, adopts a passive control damping mechanism coupled with a dynamically adjusted interconnection coefficient. This ensures a smooth stability of DU subsystems, even when faced with significant disturbances. Rigorous theoretical analyses, underpinned by the Lyapunov theorem, corroborate the systemic stability conferred by the DEC design. Furthermore, it demonstrates robustness against unforeseen input voltage variations. Simulations and experiments demonstrate that the proposed control approach accelerates system recovery and broadens the stability margin.",

The system features advanced grid support functionalities based on IEEE 1547-2018, implemented on the inverter side. The rectifier-side controller ensures reference following for active and/or reactive powers and maintains the commanded dc bus voltage. The inverter-side controller ensures power command following for active and reactive powers. The proposed control architecture is designed to suppress second-harmonic oscillations in powers during unbalanced grid voltage sags by dynamically adjusting the currents on each ac side. This also ensures effective elimination of any second-harmonic oscillations in the equivalent dc bus voltage. Validation is performed on an OPAL-RT Technologies Inc. (OPAL-RT) real-time platform with case studies on unbalanced and balanced sags, demonstrating the controller’s effectiveness during real-time implementation. A reduced-scale laboratory prototype further verifies these case studies, with experimental results for balanced sags due to grid simulator limitations. The results confirm the robustness and efficiency of the proposed control strategy in ensuring stable and reliable operation under various grid conditions.",

      "abstract": "To overcome the heterogeneous dynamics and unreliable communication which adversely effect the stable control for connected and automated vehicle platoons, a new intelligent control approach, named virtual order-degradation interconnection and damping assignment (VO-IDA), is proposed in this article. First, the internal stability of vehicle platoons is ed into a class of tracking control problems for general chained integral systems. By converting the chained integral system into standard closed-loop port-controlled Hamiltonian form, VO-IDA achieves asymptotic tracking through the integration of backstepping order degradation and virtual stabilization control techniques. This conversion effectively eliminates the dependence on preceding vehicular acceleration as well. Second, under heterogeneous dynamics, explicit stable domains of control parameters are provided to ensure the attenuation of string stability for vehicle platoons via Laplace transform. Furthermore, a linear-proportional relationship between heterogeneous and homogeneous dynamics regarding spacing error ratio is uncovered. Leveraging this relationship, a modified multiobjective genetic algorithm is employed to online explore target locations within stable domains, enabling VO-IDA to conduct stable and precise control under heterogeneous dynamics. Comparative experiments verify the superiority of this approach.",

      "abstract": "This article incorporates free-surface and ambient wave effects into a nonlinear parametric model. Subsequently, its use is demonstrated via simulation of a scale model submarine maneuvering under the control of a nonlinear depth-keeping control system in a seaway. An energy-based model is presented, which represents the underactuated submarine in a free-surface-affected state. This model is then used to synthesize a control law using port-Hamiltonian theory and interconnection and damping assignment passivity-based control. The Lyapunov analysis is used to study the stability of the closed-loop system, and a simulation-based demonstration illustrates the performance of the control law. The results demonstrate that a closed-loop nonlinear controller is able to improve the quality of near-surface depth keeping by automatically compensating for parasitic effects in the hydrodynamics that can compromise depth-keeping performance during maneuvers.",

      "abstract": "In this paper, we consider memristors, meminductors, and memcapacitors and their properties as port-Hamiltonian systems. The port-Hamiltonian formalism naturally arises from network modeling of physical systems in a variety of domains. Exposing the relation between the energy storage, dissipation, and interconnection structure, this framework underscores the physics of the system. One of the strong aspects of the port-Hamiltonian formalism is that a power-preserving interconnection between port-Hamiltonian systems results in another port-Hamiltonian system with composite energy, dissipation, and interconnection structure. This feature can advantageously be used to model, analyze, and simulate networks consisting of complex interconnections of both conventional and memory circuit elements. Furthermore, the port-Hamiltonian formalism naturally extends the fundamental properties of the memory elements beyond the realm of electrical circuits.",

      "abstract": "Algebraic graph theory is a cornerstone in the study of electrical networks ranging from miniature integrated circuits to continental-scale power systems. Conversely, many fundamental results of algebraic graph theory were laid out by early electrical circuit analysts. In this paper, we survey some fundamental and historic as well as recent results on how algebraic graph theory informs electrical network analysis, dynamics, and design. In particular, we review the algebraic and spectral properties of graph adjacency, Laplacian, incidence, and resistance matrices and how they relate to the analysis, network reduction, and dynamics of certain classes of electrical networks. We study these relations for models of increasing complexity ranging from static resistive direct current (dc) circuits, over dynamic resistor..inductor..capacitor (RLC) circuits, to nonlinear alternating current (ac) power flow. We conclude this paper by presenting a set of fundamental open questions at the intersection of algebraic graph theory and electrical networks.",

      "abstract": "This letter deals with nonlinear repetitive control (RC), a technique used to reject periodic disturbances with a known and constant period. Since RC systems are defined over a state space of infinite dimension, the main theoretical problem that makes nonlinear case not trivial resides in the lack of adequate mathematical tools to study well-posedness of the closed-loop system and regularity of the solutions. Here, the stability analysis relies on recent results about the boundary control of infinite-dimensional port-Hamiltonian systems via nonlinear regulators, and the major contribution is the definition of a class of nonlinear plants for which a RC scheme is, at first, well-posed, and then exponentially stable. Moreover, an explicit proof of perfect local asymptotic tracking and disturbance rejection for exponentially stable RC systems is provided.",

      "abstract": "Scientists have long been attracted to mechanisms surrounding the predator–prey system. The Lotka–Volterra (LV) model is the most popular formalism used to investigate the dynamics of this system. LV equations present non-linear dynamics that exhibit periodic oscillations in both prey and predator populations. In practical situations, it is useful to stabilise the system asymptotically to a desired set point (population) wherein the two species coexist by fashioning specific control actions. This control strategy can be beneficial for problems that can arise when there is a risk of extinction of one of the species and human intervention must be planned. One natural and well-established theory for describing systems obeying energy balance laws is the port-Hamiltonian modeling, an extension of classical Hamiltonian mechanics to systems endowed with control and observation. The LV model can be formally represented as a non-linear mechanical oscillator employing the canonical equations of Hamilton. This special mathematical structure aids planning and designing efficient control actions. The proposed strategy employs a systematic procedure to efficiently plan biological control actions and bypass species extinction through asymptotic stabilisation of populations.",

      "abstract": "This letter proposes a novel framework to design a passivity based sliding mode controller for mechanical systems described by simple port-Hamiltonian systems. For this class of systems, passivity based control is often used to design a stabilizing controller which employs a physical energy of the plant system as a Lyapunov function candidate. This letter proves that there exist a special class of passivity based controllers which coincide with sliding mode ones. This approach enables us to obtain sliding mode control systems with explicit energy based Lyapunov functions. The proposed approach requires a kind of matching condition under which the two control schemes coincide with each other. How to relax the condition is also discussed. Furthermore, a numerical example demonstrates how the proposed method works.",

Using the port-Hamiltonian framework, two decentralized passivity-based control schemes are designed.

Thus, the observer-error dynamics are reformulated as an abstract Cauchy problem, which enables to draw conclusions regarding the well-posedness of the observer-error system. Furthermore, we show that the observer error is asymptotically stable by applying LaSalle’s invariance principle.",

      "abstract": "In this letter, we propose a passivity-based control technique, where the resulting controllers can be interpreted as lag-compensators for nonlinear mechanical systems described in the port-Hamiltonian framework. The proposed methodology considers a dynamic controller such that the relationship between the control input and the error signal of interest can be expressed in terms of a transfer function. Accordingly, the control gains can be tuned through a frequency analysis approach. Additionally, two practical advantages of the resulting controllers are that they do not require velocity measurements, and they can cope with input saturation. We illustrate the applicability of the proposed methodology through the stabilization of a planar manipulator, where the experimental results corroborate the effectiveness of the technique.",

      "abstract": "Task-invariant control methods for powered exoskeletons provide flexibility in assisting humans across multiple activities and environments. Energy shaping control serves this purpose by altering the human body’s dynamic characteristics in closed loop. Our previous work on potential energy shaping alters the gravitational vector to reduce the user’s perceived gravity, but this method cannot provide velocity-dependent assistance. The interconnection and damping assignment passivity-based control (IDA-PBC) method provides more freedom to shape a dynamical system’s energy through the interconnection structure of a port-controlled Hamiltonian system model. This letter derives a novel energetic control strategy based on IDA-PBC for a backdrivable knee-ankle exoskeleton. The control law provides torques that depend on various basis functions related to gravitational and gyroscopic terms. We optimize a set of constant weighting parameters for these basis functions to obtain a control law that produces able-bodied joint torques during walking on multiple ground slopes. We perform experiments with an able-bodied human subject wearing a knee-ankle exoskeleton to demonstrate reduced activation in certain lower-limb muscles.",

A port-Hamiltonian formulation is employed to describe the system dynamics, which includes the pressure dynamics of the hydraulic fluid. A new nonlinear control law is constructed with an energy-shaping approach, and it is combined with an adaptive observer to compensate the effect of unknown external forces. Stability conditions are investigated with a Lyapunov approach, and the effect of the tuning parameters and of key model parameters is discussed. The effectiveness of the controller is demonstrated with numerical simulations.",

A dynamical model of the system which accounts for the energy of the ideal gas is presented by employing the port-Hamiltonian formulation. A new control law is constructed with an energy shaping approach. An adaptive observer is employed to compensate the effect of external forces, including that of gravity. Numerical simulations indicate that the proposed controller is superior to simpler energy shaping algorithms.",

Similarly to continuous-time approaches, the synthesis is based on the mapping via state-feedback of the open-loop error system to a target one in port-Hamiltonian form, and with an asymptotically stable origin that corresponds to the perfect tracking condition. The procedure is formally described by a matching equation that, in continuous-time, turns out to be a nonlinear partial differential equation (PDE). This is not the case for sampled-data systems, so an algebraic approach is proposed. The solution is employed to construct a dynamical regulator that performs an “approximated” mapping. The stability analysis relies on Lyapunov arguments.",

      "abstract": "In this letter, we consider the exponential stabilization of a distributed parameter port-Hamiltonian system interconnected with an unstable finite-dimensional linear system at its free end and control input at the opposite one. The infinite-dimensional system can also have in-domain anti-damping. The control design passes through the definition of a finite-dimensional linear system that “embeds” the response of the distributed parameter model, and that can be stabilized by acting on the available control input. The conditions that link the exponential stability of the latter system with the exponential stability of the original one are obtained thanks to a Lyapunov analysis. Simulations are presented to show the pros and cons of the proposed synthesis methodology.",

      "abstract": "A recent formalization of thermodynamics under a dynamical systems approach introduces an axiom restricting the direction of power transmission between two subsystems, reflecting heat transfer from hot to cold bodies. This axiom enables precise results paralleling the statements of classical thermodynamics, including its second law, which places a limit on the amount of work that may be transferred to across system boundaries beyond that imposed by energy conservation. Systems exhibiting non-diffusive power transfer, including those with Hamiltonian dynamics are ruled out. Given that power networks with Hamiltonian dynamics fail the directionality axiom, are they still subject to limitations on their ability to perform work on the surroundings? This letter shows that such systems can satisfy a version of the above axiom involving averages over periodic regimes, revealing limitations on external power transfer and allowing a definition of second-law efficiency and a cyclic interpretation of energy equipartition. Focus is on a class of linear port-Hamiltonian systems, with frequency-domain methods used to describe the pertinent average quantities. The ability to establish an order relationship between the weighted average kinetic and potential energies has a central role. We show that this can be cast as a generalized eigenvalue problem.",

The quality of the proposed passivity-based control is validated and compared through simulations with the existing literature and the continuous-time implementation using the unicycle as a case study.",

      "abstract": "This letter investigates the design of a class of infinite-dimensional observers for one dimensional (1D) boundary controlled port-Hamiltonian systems (BC-PHS) defined by differential operators of order $N \\geq 1$. The convergence of the proposed observer depends on the number and location of available boundary measurements. Asymptotic convergence is assured for $N\\geq 1$, and provided that enough boundary measurements are available, exponential convergence can be assured for the cases $N=1$ and $N=2$. Furthermore, in the case of partitioned BC-PHS with $N=2$, such as the Euler-Bernoulli beam, it is shown that exponential convergence can be assured considering less available measurements. The Euler-Bernoulli beam model is used to illustrate the design of the proposed observers and to perform numerical simulations.",

The results provide an energetic interpretation of safety-critical control schemes, and induce novel passive designs with respect to standard methods based on damping injection. The results are specialised to port-Hamiltonian systems and simulations are performed on a cart-pole system.",

In this letter, a one-dimensional wave equation with a partially reflective boundary is approximated using a first-order mixed finite element method. The multiplier method is used to prove that the approximated systems are exponentially stable with a decay rate independent of the mesh size. Upper bounds on the exponential decay are obtained in terms of the physical parameters.",

To show the effectiveness of the proposed approach, we use the projection dynamics on the tangent cone for stabilizing boost converters in a DC microgrid while satisfying predefined input constraints.",

      "abstract": "Interconnection schemes are ubiquitous in physical systems. For instance, in multi-domain systems consisting of interconnected subsystems from different physical domains. Furthermore, the interconnection of two or more systems has also been exploited to analyze and control dynamical systems, especially passive ones. To this end, the most common interconnection structure is the negative feedback interconnection. However, this approach is unsuitable to directly couple the states of the subsystems in the overall system’s energy as customarily occurs in physical systems. This letter provides two interconnection approaches that overcome this issue. Notably, it is shown that these interconnection structures are suitable for decomposing passive systems into the interconnection of simpler passive subsystems. Moreover, these interconnections schemes allow the interpretation of some existing nonlinear control approaches as the interconnection of a passive plant with a passive controller. Additionally, the interpretation of the proposed interconnection structures is provided via bond graphs.",

      "abstract": "This letter proposes a passivity based integral sliding mode controller for mechanical port-Hamiltonian systems. Recently, passivity based sliding mode control (PBSMC) has been proposed for mechanical and electro-mechanical systems. This method has properties of both sliding mode control (SMC) and passivity based control. However, the robustness of the closed-loop system is not guaranteed in the reaching phase. For this problem, integral sliding mode control (ISMC), which eliminates the reaching phase, has been proposed. This letter proposes a unified control method of passivity based control and integral sliding mode control based on the idea of PBSMC. In order to achieve ISMC in the port-Hamiltonian form, an integral term of the sliding variable of PBSMC is firstly added to the system equation. Next, by adding an appropriate potential function to the Hamiltonian function, the dynamics of ISMC is obtained. The proposed method is more robust than PBSMC and ensures Lyapunov stability even if the resulting feedback controller is replaced by its continuous approximation to alleviate the chattering phenomena. The effectiveness of the proposed method is demonstrated by a numerical example.",

In particular, we design a threshold parameter for the event-triggering condition, a sampling period, and a maximum allowable delay such that interconnected port-Hamiltonian control systems with periodic event-triggering mechanism under a time-delayed communication are able to achieve asymptotically stable behaviour. Simulation results are presented to validate the theory.",

      "abstract": "This letter introduces a new framework of nonlinear, discrete-time, boundary control systems (BCSs) in the port-Hamiltonian form. The contribution is twofold. We start with a discrete-time approximation of a nonlinear port-Hamiltonian BCS, i.e., a dynamical system modelled by a nonlinear partial differential equation with boundary actuation and sensing. The most important feature is that the discretisation is performed in time only so that the “distributed nature” of the state is preserved. By approximating the gradient of the Hamiltonian density with its discrete gradient, the obtained sampled dynamics inherit the passivity of the original one. Besides, we prove that, under mild conditions, it is well-posed, i.e., the “next” state always exists. The second contribution deals with control design. More precisely, we have determined sufficient conditions for the plant dynamics and a static output feedback gain to make the closed-loop system asymptotically stable.",

      "abstract": "Linear quadratic differential games and their feedback Nash equilibrium (F-NE) solutions are considered. First, it is shown that F-NE strategies can be derived from the restriction to an invariant subspace of a system that is reminiscent of the state/costate dynamics arising in the context of open-loop NE solutions. Second, in terms of synthesis, it is shown that the equilibrium subspace can be rendered externally stable via virtual inputs without modifying the underlying F-NE strategies. Building upon these findings, we propose a gradient descent algorithm to determine a solution of the coupled Algebraic Riccati Equations associated with F-NE, which are generally challenging to solve. Finally, in terms of analysis, we show that the F-NE strategy of each player can be interpreted as the output of a passive Port-Controlled Hamiltonian system, and that the behaviour of the original system under the action of the F-NE strategies can be interpreted as an interconnection of these.",

      "abstract": "This letter examines the dynamic properties of a hybrid momentum observer for mechanical systems, extending the previously-reported results. The observer estimates the momentum vector from measurements of the configuration vector and is shown to be input-to-state stable with respect to external perturbations. In the absence of external perturbation the observer is shown to be globally exponentially stable, converging at a user-controlled rate. The observer is constructed from a port-Hamiltonian representation of mechanical systems and exhibits a passivity property with respect to an input-output port that can be utilised for subsequent control design. The theoretical results are demonstrated via numerical simulation on a 2-link vertical manipulator.",

      "abstract": "In this note, we propose a method for describing the dynamics of mechanical systems with velocity-based inputs within the port-Hamiltonian framework. Canonical representations of mechanical systems assume force/torque inputs. Many commonly used actuators, however, have internal dynamics that cause the output velocity to quickly converge to a specified reference velocity. In such cases, it is more meaningful from a modeling and control perspective to define models that admit a velocity input. This is achieved in this letter by performing a momentum transformation and state reduction, resulting in a reduced-order model where the relevant velocity is a causal input. The reduced-order model preserves the passivity of the original port-Hamiltonian system. The results are demonstrated by applying a velocity-input control signal to the classical cart-pole system.",

      "abstract": "Rigid body platoons are widely applied in many scenarios, such as planar vehicular platoons, satellite networks, and aerial/underwater navigation formations. Like string stability, mesh stability is adopted in these higher dimensional platoons to capture the non-increasing tracking errors over the networks. In this letter, we extend the traditional vehicular platooning control to higher dimensional rigid body scenarios with mesh stability concerns. The main challenges stem from the inherent underactuation of rigid body dynamics, the nonlinearity introduced by the $SO\\textit {(}3\\textit {)}$-based rotations, and the maintenance of mesh stability for all formations. To this end, we first apply the notion of $l_{2}$ weak mesh stability to capture the effect of propagation of errors over the network. Then, by assuming all the followers have access to the leader’s information, we propose a novel and constructive rigid body platooning control method based on the port-Hamiltonian framework, which also guarantees the $l_{2}$ weak mesh stability. This designed controller is further refined for the case when each follower only knows the neighboring information. Finally, the effectiveness of the proposed methods is verified via numerical simulations.",

The port-Hamiltonian framework offers advantages in modeling networks, dissipation, and heterogeneous agents. In this regard, designing flocking controllers in port-Hamiltonian form significantly increases their practical applications. Additionally, event-triggered control has proven effective in reducing bandwidth consumption. However, challenges remain in combining flocking requirements with energy-dissipating terms. Therefore, we propose a novel event-triggered flocking controller suitable for port-Hamiltonian systems. The method is validated through numerical simulations of a group of hexarotors.",

      "abstract": "In this letter, we study the energy-optimal control of nonlinear port-Hamiltonian (pH) systems in discrete time. For continuous-time pH systems, energy-optimal control problems are strictly dissipative by design. This property, stating that the system to be optimized is dissipative with the cost functional as a supply rate, implies a stable long-term behavior of optimal solutions and enables stability results in predictive control. In this letter, we show that the crucial property of strict dissipativity is not straightforwardly preserved by any energy-preserving integrator such as the implicit midpoint rule. Then, we prove that discretizations via difference and differential representations lead to strictly dissipative discrete-time optimal control problems. Consequently, we rigorously show a stable long-term behavior of optimal solutions in the form of a manifold (subspace) turnpike property. Finally, we validate our findings using two numerical examples.",

      "abstract": "This letter deals with discrete-time linear boundary control systems (BCSs) in port-Hamiltonian form, for which the discretization is performed in time while preserving the distributed nature of the state and the passivity of the original system. The contribution is twofold. First, an explicit parametrized expression of the discrete-time state evolution is derived. Second, this parametrization is employed to design a simple model predictive control (MPC) law. The receding-horizon scheme relies on an optimization procedure based on a quadratically constrained quadratic programming (QCQP) problem. By following standard arguments and exploiting the passivity of the BCS, we prove that the MPC methodology guarantees asymptotic stability.",

      "abstract": "In this work, we approach the control problem of fully-actuated UAVs in a geometric port-Hamiltonian framework. The UAV is modeled as a floating rigid body on the special Euclidean group SE(3). A unified near-hovering motion and impedance controller is derived by the energy-balancing passivity-based control technique. A detailed analysis of the closed-loop system's behavior is presented for both the free-flight stability and contact stability of the UAV. The robustness of the control system to uncertainties is validated by several experiments, in which the UAV is controlled near its actuator limits. The experiments show the ability of the UAV to hover at its maximum allowed roll angle and apply its maximum allowed normal force to a surface, without the input saturation destabilizing the system.",

      "abstract": "This paper deals with the modeling and control problem of a Hydraulically Amplified Self-healing Electrostatic (HASEL) actuator based on the port-Hamiltonian framework. A nonlinear spring-damper system is used to approximate the mechanical deformation of the actuator due to the motion of the fluid while a nonlinear capacitance is used to approximate the electric behavior of the system. The actuator position control strategy is investigated based on the Interconnection Damping Assignment-Passivity Based Control (IDA-PBC) method, with further Integral Actions (IA) added to cope with load uncertainties. The proposed model and control laws are validated on an experimental benchmark. The experimental tests demonstrate that the proposed model is accurate up to 94% of fitness. The controllers allow assigning the actuator position with ramp and sinusoidal references with the relative error less than 5%. At last, the robustness of the proposed IDA-PBC controller with IA has been shown with the experimental result for the unknown load disturbance rejection.",

      "abstract": "Existing tensegrity robot modeling predominantly relies on cable length as the primary control input, making it intractable for implementation on motor-driven physical systems. In addition, the current models lack precise formulations for intricate environmental interactions, such as ground contact forces during deformation and rolling maneuvers. To bridge these gaps, our study proposes a practicable modeling approach tailored for six-bar tensegrity robots within the Port-Hamiltonian framework. We address the internal forces stemming from interconnected bars and cables by elegantly formulating them as Hamiltonian expressions. Central to our modeling is the versatile “port”, encompassing contact and friction forces, and motor-driven propulsion. These considerations exhibit a broad applicability to cable-driven tensegrity robots, facilitating the straightforward deployment of controllers on real-world robotic platforms. The system parameters are identified via experiments on our prototype tensegrity robot, with results aligning closely with theoretical analyses. In summary, our work offers a refined modeling perspective overcoming challenges in control inputs and environmental interactions, validated through prototype experiments.",

      "abstract": "Pneumatic artificial muscles (PAMs) are soft actuators with softness and high power ratio. These characteristics provide a robot with adaptiveness and agility. However, controlling PAMs is difficult because they exhibit a highly nonlinear nature and involve complex multi-physical systems (i.e. mechanical and fluid systems). In particular, to achieve better control performance, the conventional approach suffers from estimating difficult-to-estimate parameters, such as the viscoelasticity of the PAM. To overcome the difficulty of controlling PAMs, this study utilized an interconnection and damping assignment passivity-based control (IDA-PBC) method via port-Hamiltonian (PH) framework. PH framework is well-suited for modeling PAMs because this framework describes the energy exchanges between the multi-physical systems of PMAs. In addition, the IDA-PBC method is a passivity based control that stabilizes the nonlinear systems. Loosely speaking, the feedback gain of the IDA-PBC method must be determined such that the PAM system is passive – that is, it either dissipates or conserves energy. Therefore, the PAM system can be stabilized without the precise viscoelastic parameters when the feedback gains are significantly higher than these parameters and ensure the system's passivity. Several experiments compared our proposed control with comparison control methods. As a result, our proposed control followed the desired position with a smaller error than the other comparison methods across a wide range of target positions.",

      "abstract": "Human collaboration with robots requires flexible role adaptation, enabling the robot to switch between an active leader and a passive follower. Effective role switching depends on accurately estimating human intentions, which is typically achieved through external force analysis, nominal robot dynamics, or data-driven approaches. However, these methods are primarily effective in contact-sparse environments. When robots under hybrid or unified force–impedance control physically interact with active humans or non-passive environments, the robotic system may lose passivity and thus compromise safety. To address this challenge, this letter proposes a unified Interactive Force-Impedance Control (IFIC) framework that adapts to interaction power flow, ensuring safe and effortless interaction in contact-rich environments. The proposed control architecture is formulated within a port-Hamiltonian framework, incorporating both interaction and task control ports, thereby guaranteeing autonomous system passivity. Experiments in both rigid and soft contact scenarios demonstrate that IFIC ensures stable collaboration under active human interaction, reduces contact impact forces and interaction force oscillations.",

Power, the rate of energy transport between components, is the universal currency of physical systems. Bond graphs are inherently energy based and thus related to other energy-based methods, including dissipative systems and port-Hamiltonians. This article has presented an introduction to bond graphs for control engineers. Although the notation can initially appear daunting, the bond graph method is firmly grounded in the familiar concepts of energy and power. The essential element to be grasped is that bonds represent power transactions between components",

In our contribution we present a systematic approach to fix constant parameters of the design matrices of IDA-PBC, such that the closed loop system behaves like a linear sample system in the environment of the assigned equilibrium, while (nonlinear) asymptotic stability is guaranteed with the standard IDA-PBC arguments. As a further result we give conditions under which a simplified, e.g., linearized control law can be applied, preserving stability of the closed loop nonlinear system.",

      "abstract": "A method to reconfigure in a nonprehensile way the pose (position and orientation) of a sphere rolling on a plate is proposed in this letter. The nonholonomic nature of the task is first solved at a planning level, where a geometric technique is employed to derive a Cartesian path to steer the sphere towards the arbitrarily desired pose. Then, an integral passivity-based control is designed to track the planned trajectory. The port-Hamiltonian formalism is employed to model the whole dynamics. Two approaches to move the plate are addressed in this paper, showing that only one of them allows the full controllability of the system. A humanoid-like robot is employed to bolster the proposed method experimentally.",

To better understand the complex dynamics of power systems, several authors suggest that such systems may be analyzed using port-Hamiltonian representations. In this work we extend this approach, and propose a port-Hamiltonian description for transmission networks which are modeled based on dq0 quantities. We present several results that show how to analyze the system stability and the behavior of the Hamiltonian. The results are demonstrated in several test cases.",

Within the port-Hamiltonian modeling framework, concepts that extend passivity margins and energy tanks are used to estimate power reserves in Hybrid Renewable Energy Systems. The methodology is applied to multi-source cells with renewable energy dedicated to the production of clean hydrogen. This work can be extended to more complex networked power systems, with the aim to increase the reliability of standalone networks by fitting the power demands while avoiding damage and extending lifetime of the equipment.",

This paper addresses the damping in suspension system augmented by the piezoelectric (PE) stack. The Hamiltonian system approach with port-power modeling of single subsystems is used for describing and studying the dissipative properties of piezoelectric stack element, integrated in series with a standard quarter-car suspension. The slightly improved, compared to the underlying passive suspension system, frequency response of the sprung mass acceleration is demonstrated. Moreover, the overall power flow in the system, caused by the disturbing road profile, and the dissipated power due to PE-augmented suspension are analyzed and discussed in detail. The results of dissipation analysis provide helpful tools for further developments towards PE-based energy harvesting.",

Specifically, using a stochastic dissipativity, losslessness, and accumulativity theory, we develop a nonlinear stochastic port-Hamiltonian system model characterized by energy conservation and entropy nonconservation laws that are consistent with statistical thermodynamic principles. In particular, we show that the difference between the stored system energy and the supplied system energy for our stochastic thermodynamic model is a martingale with respect to the system filtration, whereas the system entropy is a submartingale with respect to the system filtration.",

      "abstract": "Power-electronics-based Medium Voltage Direct Current (MVDC) shipboard power systems, consisting of several interconnected feedback-controlled switching converters, suffer from potential degradation of stability induced by negative incremental resistances due to the presence of constant power loads (CPLs). To tackle such a problem, we propose a system-level stabilizing control methods acting on the source side converters. It relies on the Port Controlled Hamiltonian (PCH) representation of a Buck Converters. Based on this approach an Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) law is designed. Simulation results for a MVDC Microgrid using converter switching models confirm the correctness and effectiveness of the designed controller while evaluating him against the well research Linearizing State Feedback (LSF).",

      "abstract": "This paper presents a cooperative, distance-based, distributed control law for multiple Autonomous Underwater Vehicles (AUVs) executing a mission while meeting mutual communications constraints. The classic graph theory provides the essential tools to model the whole network of interacting robots, which is then handled within the energy-based, port-Hamiltonian framework. The virtual interaction forces generated over each link are represented by visco-elastic couplings. The passivity theory allows the construction of a Lyapunov function for the closed loop system to demonstrate the stability in large of the whole network with the synthesized control law. Moreover, always using passivity-based techniques, the behaviour of the group is made as flexible as possible with arbitrary split and join events. Several software simulations, involving a team or sub-teams of agents that perform typical missions in marine environment, show the effectiveness of the proposed approach.",

      "abstract": "Task-specific, trajectory-based control methods commonly used in exoskeletons may be appropriate for individuals with paraplegia, but they overly constrain the volitional motion of individuals with remnant voluntary ability (representing a far larger population). Human-exoskeleton systems can be represented in the form of the Euler-Lagrange equations or, equivalently, the port-controlled Hamiltonian equations to design control laws that provide task-invariant assistance across a continuum of activities/environments by altering energetic properties of the human body. We previously introduced a port-controlled Hamiltonian framework that parameterizes the control law through basis functions related to gravitational and gyroscopic terms, which are optimized to fit normalized able-bodied joint torques across multiple walking gaits on different ground inclines. However, this approach did not have the flexibility to reproduce joint torques for a broader set of activities, including stair climbing and stand-to-sit, due to strict assumptions related to input-output passivity, which ensures the human remains in control of energy growth in the closed-loop dynamics. To provide biomimetic assistance across all primary activities of daily life, this paper generalizes this energy shaping framework by incorporating vertical ground reaction forces and global planar orientation into the basis set, while preserving passivity between the human joint torques and human joint velocities. We present an experimental implementation on a powered knee-ankle exoskeleton used by three able-bodied human subjects during walking on various inclines, ramp ascent/descent, and stand-to-sit, demonstrating the versatility of this control approach and its effect on muscular effort.",

      "abstract": "A new energy-based approach to mathematical modeling of multi-physical systems – Energetic Macroscopic Representation (EMR) has already shown its effectiveness in the study of a number objects of electric vehicle, renewable energy, energy storage systems etc. An important advantage of this approach over others is the clear procedure for creating control systems based on the principle of Inversion-Based Control (IBC). However, IBC encounters difficulties in more complex cases when the control object has multi-input subsystems with non-linear coupled dynamics. In this paper, for such cases, it is proposed to apply the description of a complex subsystem as Port Controlled Hamiltonian (PCH) and to synthesize the control system by the method of Interconnection and Damping Assignment, which will provide asymptotic stability of the nonlinear subsystem. The effectiveness of the proposed approach is demonstrated by the example of vector-controlled PMSM for both cases of mounting in the rotor of permanent magnets – surface and interior. The conducted simulation studies showed the effectiveness of the proposed approach and better control quality compared to the Field Oriented Control (FOC) of the components of the armature current vector.",

The energy of the NPC hybrid rectifier can flow in both directions, the total harmonic distortion (THD) is lower, and the converter capacity is larger. The port controlled hamiltonian with dissipation (PCHD) mathematical models of the Boost converter and the NPC rectifier are built respectively, and the passivity-based hybrid control (PBHC) controller is designed, which includes the outer voltage loop based on proportional-integral (PI) control and the inner current loop based on passivity based control. The designed control strategy is with better current tracking performance, output voltage stablity, and good robustness. The simulation model is established by MATLAB/Simulink, and the simulation results show good static and dynamic performances of the proposed control strategy.",

      "abstract": "This paper presents a novel control approach to improve the dynamic response of wind energy control systems (WECS) that use a permanent magnet synchronous generator (PMSG) operating under a wide input and load range. In this paper, it's shown that WECS is classified as a Port-Controlled Hamiltonian (PCH) system. Therefore, a nonlinear controller based on PCH is proposed, which is able to robustly control the WECS under parameter uncertainties and disturbances. The performance of the PCH-based controller is evaluated through simulation. Also, the proposed controller is implemented on an experimental prototype. Simulation and experimental results show a robust and fast transient performance compared to the conventional dq-controller.",

      "abstract": "The interest for smart-grids has grown worldwide and several utilities have begun to base their plans for expansion and modernization considering this concept. New trends to get more efficient, compact, and reliable power semiconductor devices, have motivated the development of new components such as the Solid-State Transformer (SST), which has become the key technology to be used in smart-grid applications. These advantages can be exploited by regulating the power flow in the dual-active bridge (DAB) of the SST. In this context, this paper focuses on proposing a passivity-based current controller for the DAB of an SST that regulates the power flow considering the passive behavior of DAB model and its port-Hamiltonian structure, which guarantees stability in closed-loop operation. To validate the proposed approach's effectiveness, the closed-loop system is tested under different power variations, including bi-directional power flow, and its performance is compared with a conventional PI controller. In addition, input voltage variations are also considered. Results validated the controller's capability of maintaining constant power flow in the event of input disturbances.",

      "abstract": "A low-inertial power system allows rapid fluctuations in frequency and phase under disturbances. These fluctuations can destabilize the entire system if not accounted for while estimating the control action. Therefore, fast and accurate synchronization is necessary to ensure inertial stability. However, there is a limit on the response time of synchronization controllers like a phase-locked loop (PLL) to ensure harmonic suppression and stability against a weak grid. In this context, a passivity-based controller is proposed as an alternative, which can enable fast current control and PLL response while maintaining stability and power quality. The results are compared with a proportional-integral (PI) controller while accounting for control and modulation delay.",

      "abstract": "The deployment of battery energy storage systems (BESS) plays a crucial role in enhancing the reliability and operational efficiency of renewable energy infrastructures. This study presents a resilient control strategy for BESS, implemented through a bidirectional buck–boost DC–DC converter and formulated within the extended port-Hamiltonian (EpH) framework using passivity-based control (PBC). A nonlinear averaged model is developed and expressed in EpH form, which highlights the system’s inherent passive characteristics. Stability analysis is conducted via Lyapunov theory, resulting in a dynamic controller that ensures global exponential stability. The proposed controller applies a unified control law for both charging and discharging processes, relying on a single proportional damping gain. Target state trajectories are designed to function as dynamic compensators, while robustness against parameter variations is systematically examined. MATLAB simulations validate the controller’s capability to accurately track time-varying current references and maintain precise load compensation. In comparison with conventional proportional–integral and sliding-mode controllers, the PBC-based approach demonstrates improved transient behavior, reduced tracking error, and simplified tuning requirements. Beyond offering a high-performance solution, this work also provides a practical framework for applying pH modeling and PBC theory to modern power electronic systems in renewable energy applications.",

      "abstract": "This paper presents an energy-based hybrid control, which replaces the traditional automatic voltage regulator (AVR) for excitation control of a synchronous generator connected to an infinite power system. The proposed controller is based on energy representation of the power system by using a port-controlled Hamiltonian form. The controller uses a hierarchical hybrid architecture characterized by continuous-time dynamics at the lower level of the hierarchy and logical decision-making units at the higher level of the hierarchy. The lower-level units, i.e., the subcontrollers, are each designed for a power system operating mode and directly interact with the power system to be controlled; while the higher-level decision-making units perform logical checks that identify system mode of operation and activates the corresponding lower-level unit; the activated lower-level unit then executes continuous control actions for the power system. Consequently, the controller can adapt to different power system operating modes. Simulation studies are carried out to show the effectiveness of the proposed controller for excitation control of the synchronous generator.",

This scheme characterize the global stability and strong robustness. Firstly, the frequency decoupled model of Hexverter is studied and then port-controlled Hamiltonian (PCH) model is built. On this basis, the IDA-PB control scheme of the Hexverter is designed. Considering the interference of system parameters and unmolded dynamics, integrators are added to the IDA-PB controller to eliminate the steady-state error. Finally, The simulation results are presented to verify that the proposed control scheme have good operation performance and strong robustness.",

      "abstract": "With the integration of more and more power electronics devices into the grid, it is not easy to guarantee the stability of the whole system due to the complexity of the control structure of various power converters. In this paper, we consider grid-forming and grid-following converters in one microgrid, in which the grid-forming converters support the voltage and frequency of the microgrid and the grid-following converters inject their maximum power into the microgrid. To handle the stability issue, the passivity principle is applied to guarantee the stability of the whole microgrid. We ensure every grid-following converter satisfies the passivity via the port-controlled Hamiltonian method. In addition, we apply the passivity-based proportional-resonant controller to the grid-forming converter. One of the advantages of the proposed method is that the phase lock loop system is eliminated, which may cause stability issues. Simulation results show that the proposed method can control the microgrid effectively.",

      "abstract": "In multiple parallel grid-following converters (GFL-VSCs), the nonlinear characteristics of the phase-locked loop (PLL) and other PLLs coupling interactions significantly affect the transient synchronization stability (TSS) of the GFL-VSCs. To fill this gap, this paper investigates the impact of coupling interactions based on the stability region boundary (SRB) theory. The study reveals that the coupling interactions limit the maximum phase angle of the PLL. Based on this, the stable manifold of GFL-VSCs is plotted using the differential-algebraic equation (DAE) SRB theory. It is shown that SRB of GFL-VSCs is composed of stable manifolds of unstable equilibrium point (UEP) or stable manifolds of semi-singular point (SSP) and partial singular surfaces. The composition of the SRB is closely tied to the influence of coupling interactions between PLLs. Furthermore, we propose a quantitative index based on the port-Hamiltonian (PH) energy function to assess the impact of coupling interactions on TSS. This method is implemented by comparing the critical energy values at the saddle points. This approach does not require internal measurements or model parameters, making it convenient for online applications. Finally, experiments and simulations were conducted to compare with existing methods, validating the effectiveness of the proposed approach.",

Based on the energy-dissipative property of APF state equations, the averaged PCH model in the d–q rotating frame with periodic disturbances, aperiodic disturbances and parametric perturbations is first established. The averaged PCH model of error system is further derived in terms of energy balance. Then, the influence of parametric perturbations can be converted into part of periodic disturbances and periodic adaptive L2 disturbance attenuation control algorithm is designed to suppress tracking errors resulted from parametric perturbations and disturbances: The periodic adaptive control compensates periodic disturbances, while the L2 disturbance attenuation can be used to stabilize the error system, ensure the convergence of periodic adaptive control and suppress other aperiodic disturbances. In addition, according to the demand in practical implementation, the proposed control algorithm is modified by ignoring the ripple component on dc-side capacitor reference voltage. Experimental results verify the validity of the proposed algorithm.",

      "abstract": "Recently, several power grids of China came across low frequency oscillations which are difficult to explain by the traditional negative damping mechanism. Some researchers suggest that those oscillations be caused by external periodic disturbances according to the forced oscillation mechanism. It takes no doubt that the oscillation source location (means locating the disturbances) is imperative and decisive to eliminate such a kind of oscillations. This paper proposes a location methodology based on Energy Supply on Port derived from the Port-Controlled Hamiltonian theory. By calculating the energy injected to the network at corresponding ports, the oscillation sources can be effectively located, even in complicated systems containing various kinds of control devices such as governors and exciters. Different from the traditional methodology based on eigen-analysis, the proposed methodology is naturally decentralized without the dependency on global measurements. Case studies on the standard 4-machine 2-area system and the IEEE-118 bus system show the effectiveness and efficiency of the proposed methodology.",

The PBC based on port-controlled Hamiltonian with dissipation (PCHD) model is designed for fast feedback tracking and stabilization of the nominal PCS. Then, the lumped disturbances are estimated by a nonlinear disturbance observer and compensated by feedforward term. Details on the design of baseline PBC, the nonlinear disturbance observer and stability robustness analysis are provided in this paper. With proposed method, a noticeable robustness against the lumped disturbances can be achieved as no more accurate system model is need for PBC method. The proposed method is implemented and validated through a down-scaled laboratory prototype. The simulation and experimental results are compared with the conventional PI and PBC methods, confirming that the proposed method can successfully achieve a good performance in zero steady-state tracking error, fast dynamic response and decoupling effectiveness against the lumped disturbances.",

      "abstract": "This paper presents a nonlinear controller for a permanent-magnet synchronous generator (PMSG) wind turbine system in the framework of port-controlled Hamiltonian system. For the simplification, this work focuses on the nonlinear control law of the grid side converter (GSC) that is directly connected to the grid and affected during network disturbances. The proposed controller is designed through the analysis of PMSG GSC model from the passivity viewpoint in order to regulate the reference of the DC voltage and track the reference of the reactive current. In order to fulfill low voltage ride through requirements, a DC chopper is used to dissipate surplus active power in the DC-link. By using the proposed method, the exponential stability of the equilibrium point of the error dynamics at the origin is guaranteed through Lyapunov theory. Finally, the proposed method is validated through simulation by using SimPowerSystems, MATLAB/Simulink. The simulation results show that the performance has smaller overshoot and faster convergence when the proposed method is used than when the conventional method is used.",

In order to control this kind of systems more effectively, many new control theories and methods are explored to use to design controller. Among these methods, the energy-based control design method has gained a lot of attentions in these years, which can provide more physical insights in nonlinear control. Especially, the port-controlled Hamiltonian system and generalized canonical transformation has some advantages on the modeling and control design of these nonlinear systems. In this paper, we proposed a control design for two-link flexible manipulators via generalized canonical transformation, arid the simulation results are shown to prove the effectiveness of the controllers.",

Firstly, based on the port-controlled Hamiltonian (PCH) systems theory, a PCH position tracking control model of PMSM is established. Secondly, using closed-loop state error PCH control and MTPA method, the control strategy of PMSM is presented when load torque is known and unknown. The control problem of the PMSM is reduced to the solution of a partial differential equation. The partial differential equation can be transformed into a set of general differential equation by assigning desired interconnection and damping matrix. Finally, the equilibrium stability is also analyzed. The simulation results show that the proposed scheme exhibits good position tracking control and load torque disturbances attenuation performances.",

      "abstract": "This paper studys a multi-phase boost converter for fuel cell (FC) applications. An original control law based on the Hamiltonian energy control principle for dc microgrid is considered. Using the port-controlled Hamiltonian property, we propose simple solutions to the system performance and stabilization problems when the interaction between power sources and constant power loads (CPLs). To corroborate the proposed control law, a prototype FC power converter (2.5-kW two-phase boost converter) is implemented in the laboratory. The Methanol FC system includes a fuel reformer that converts methanol and water liquid fuel into hydrogen gas to polymer electrolyte membrane FC (PEMFC) stack (2.5-kW, 50 V). The proposed control approach is realized with a digital estimate in a dSPACE MicroLabBox controller card. The experimental and simulation results verify that this is a good control scheme during constant power load cycles.",

      "abstract": "This paper studies two dynamic positioning ship systems’ simultaneous stabilization problem. The Hamilton function method is used to study the issue of simultaneous stabilization with unknown disturbance, and the related controllers are designed. First of all, we transform the dynamic positioning ship model into port controlled Hamiltonian (PCH) model, and the general simultaneous stabilization conditions are developed. Based on which, by adding the external interference, the robust controller is designed. Finally, the simulation results are tested by an illustrative example, which is shown to meet the expected requirements, and prove the rationality of the designed controller.",

      "abstract": "Soft pneumatic actuators are very popular in the soft robotic community due to their ease of manufacturing and simplicity of control. Currently, the efficiency of such soft actuators and their ability to do useful work are rarely investigated in a formal approach. The lack of task-orientated development approaches presents a barrier to utilize soft robotic systems in our everyday lives. In this paper, we describe an experimental approach based on port-Hamiltonian theory applied on a type of pneumatic network (pneu-net) actuator to investigate the efficiency of task-orientated work. We can obtain efficiency from the external interactions of the port-Hamiltonian system. If we can minimize the internal energy interactions, then the power continuous nature of the port-Hamiltonian structure ensures more input energy will result in more useful work done at the output. We found out that higher efficiency actuators can be achieved with a softer material and a thinner wall thickness in the desired direction of the deformation. The internal mechanical energy storage is reduced as a result. However, if the task requires a higher work-done then a stiffer material is required. We can start to define a design approach based on the task. The task can be generalized in terms of energy. We can select the material properties suitable for the magnitude of work done. We can design the geometry to minimize the internal energy stored. The empirical model of the port-Hamiltonian structure provides insights into how the mechanical efficiency varies in terms of design parameters and the port-Hamiltonian approach is a step towards more practical, task-orientated soft robotic systems.",

We show how very simple equations are obtained for the example of the snakeboard, and then discuss how these equations can be used to derive an energy-based controller in an intuitive way.",

      "abstract": "In this paper, the port Hamiltonian model of a manipulator is presented as the result of the power-conserving interconnection of a set of main components (rigid bodies, flexible links and kinematic pairs). Since rigid bodies and flexible links are described within the port Hamiltonian formalism, their interconnection is possible once a proper relation between the power conjugated port variables is deduced. These relations are the analogous of the Kirchoff laws of circuit theory. The final model is a mixed port Hamiltonian system because of the presence of a finite dimensional subsystem modelling the rigid bodies and of an infinite dimensional one describing the flexible links. The intrinsic modularity of the approach simplifies the model deduction and simulation, while the Hamiltonian description suggests the development of energy-based controllers",

First, we propose a generation method based on an asymptotic stabilization method without damping assignment. This asymptotic stabilization method preserves the Hamiltonian structure in the closed-loop system although the controller itself is not a port-Hamiltonian system. Second, we propose another method based on an adaptive asymptotic stabilization method for unknown damping. This adaptive asymptotic stabilizer does not use the value and the sign of the damping at all. Finally, we confirm the effectiveness of our techniques in some numerical simulation.",

      "abstract": "In this paper, two problems related to the simulation of virtual environments for haptic systems are considered. The first problem is how to simulate, in discrete time and with low computational effort, dynamic systems in order to preserve their passivity properties. As a matter of fact, simulation of complex systems in real time may lead to undesired effects, like unstable behaviours of the haptic interface, if proper care is not given to the definition of the simulation algorithm. An algorithm is presented here able to maintain the passivity properties of the physical (simulated) system with a reduced computational complexity. The second problem discussed in this paper is the interconnection of algorithms running at different frequencies, i.e., the control algorithm of the haptic interface (running typically at high frequency) and the algorithm simulating the virtual environment (running at lower frequency). A proper software interface, able to connect these two algorithms in an energetic-consistent manner, is presented and discussed. The general framework of both these techniques is the passivity theory and the so-called port-Hamiltonian formalism.",

      "abstract": "Passivity of virtual environments running in discrete time is a sufficient condition for stability of the system. The framework for passive sampled Port-Hamiltonian systems allows multi-dimensional virtual environments exhibiting internal dynamic behavior to be computed on a discrete medium in a passive manner. It is shown that a causality analysis is required in the framework to detect if any of the model elements have, a time dependent change of energy function in the energy balance of the system. The Standard Linear Solid model, which is often used to simulate the visco-elastic interaction with soft biological tissue is used as an example. Simulated and experimental results are provided to demonstrate the benefit of the described framework. It is shown that using this approach a multidimensional model which is passive in the continuous domain remains passive in the discrete domain, whereas a standard discretization approach can become non-passive.",

Such feedback provides the remote pilot with an intuitive feel of the robot's state and perceived local environment that will ensure simple and safe operation in cluttered 3D environments common in inspection and surveillance tasks. Our approach is based on energetic considerations and uses the concepts of network theory and port-Hamiltonian systems. We provide a general framework for addressing problems such as mapping the limited stroke of a ‘master’ joystick to the infinite stroke of a ‘slave’ vehicle, while preserving passivity of the closed-loop system in the face of potential time delays in communications links and limited sensor data.",

A brief literature survey reveals the need for minimal component designs and the benefits of impedance control schemes for interaction tasks such as grasping. The novel robotic finger concept supports these insights by combining three key features: minimal actuation, variable mechanical compliance and full manipulability. This combination of features allows for a minimal component design, while reducing control complexity and still providing required dexterity and grasping capabilities. The conceptual properties (such as variable compliance) are studied in a port-Hamiltonian framework. The framework proved to be suitable in analyzing and understanding the finger properties, which will be used for future controller design.",

      "abstract": "This paper presents the development of a nonlinear controller for the reaction wheel pendulum (RWP) via an interconnection and damping assignment passivity-based control (IDA-PBC) approach. The IDA-PBC approach works with the port-Hamiltonian open-loop dynamics of the RWP to propose a nonlinear controller that preserves the Hamiltonian structure in closed-loop by guaranteeing stability properties in the sense of Lyapunov. Numerical results confirm the theoretical development presented throughout simulations in Simulink package from MATLAB. Comparison with a Lyapunov-based approach is also provided.",

      "abstract": "This paper explores the controller's design for charging batteries for electric vehicle applications using the direct power representation of the system. These controllers' design is made via passivity-based control (PBC) theory by considering the open-loop port-Hamiltonian representation of the converter. The usage of PBC theory allows designing controllers for closed-loop operation, guaranteeing stability operation in the sense of Lyapunov. Two different PBC methods are explored in this contribution; these are i) interconnection and damping assignment PBC, and ii) proportional-integral design. These methods work over the system's incremental model for reaching a control law that ensures asymptotic stability. Numerical validations show that both controllers allow controlling active and reactive power independently in four-quadrants. This is important due to allow using batteries as dynamic energy compensators if it is needed. All the simulations are conducted in MATLAB simulink via SymPowerSystems library.",

An adaptive load estimator is also employed to avoid current measurements at the load point. This estimator permits an on-line estimation of the load conductance for maintaining the output voltage as constant as possible independent of its variations. The proposed PI-PBC allows guaranteeing stability conditions in Lyapunov's sense for a closed-loop operation by exploiting the port-Hamiltonian structure of the Ćuk converter model. Numerical simulations evidence the advantages of using PI actions for PBC designs compared with the classical interconnection and damping (IDA-PBC) approach.

      "abstract": "This paper addresses the problem of sinusoidal voltage generation in linear loads using a voltage source inverter (VSI). The port-Hamiltonian structure in open-loop is used to design a passivity-based controller with proportional-integral gains (PI-PBC) in order to develop the control strategy. The main advantage of using passivity-based controllers corresponds to the possibility of guaranteeing asymptotic stability by transforming the trajectory tracking problem into a regulation control one. In addition to the PI-PBC, a linear load estimator is employed based on an integral formulation to determine the value of the equivalent conductance in the load, which reduces the number of current sensors. Numerical validations demonstrate that the sinusoidal voltage provided by the VSI to the load has a tracking error lower than 1 %, with harmonic distortions lower than 2.6 %, both for voltage and currents in the load. All the simulations were conducted in MATLAB/Simulink using the SimPowerSystems library version 2017a.",

In zone III, the mechanical power harvested through the wind kinetic energy exceeds the rated generator power. Thus, when operating in this zone, the control objective is to keep the generator’s rated power constant. The classical asynchronous machine model in per unit is adapted to satisfy generator operation, power delivered to the grid at the stator winding while preserving the Port-Controlled Hamiltonian (PCH) structure. A control law is synthesized using energy-shaping control by varying the rotor angular velocity reference according to zone III demands. A series of simulations keeping the pitch angle constant are presented to show the effectiveness of the proposed methodology.",

      "abstract": "Stochastic disturbances caused by renewable energy systems (e.g., wind power and solar power) may deteriorate the transient stability problems in a power system. This paper proposes a stochastic nonlinear excitation controller for transient stability enhancement in a multimachine power system. The third-order model of generators is adopted. A new probabilistic stability criterion is presented where the magnitude of a stochastic disturbance is included explicitly. Then the whole power system is represented by a nonlinear stochastic differential equation set. The proposed excitation controller is implemented by leveraging the feature of a stochastic port-Hamiltonian system. Compared with the controller design methods based on the deterministic power system model, the proposed method can improve the system stability even in the presence of continuous stochastic disturbances on power injections. Besides, it is convenient to select the Hamiltonian function as the stochastic Lyapunov function in the proposed approach. Finally, the effectiveness of the proposed method is demonstrated by a two-area test system with a three-phase fault.",

This paper proposes a robust interconnection and damping assignment-based passivity controller design using a port-controlled Hamiltonian model with effective dynamic performance, tracking, and power quality compared to a classical controller. Classical control is combined with modern control to compute the required damping resistances of the interconnection and the damping assignmentbased passivity controller to enhance the system stability and robustness. The controller is implemented on a grid-forming converter with load variations, and the system is tested in MATLAB Simulink to validate the dynamic performance of the controller.",

      "abstract": "Traditionally, Single-Input, Multi-Output (SIMO) DC-DC converters - a category of multiport converters, have been used for multiple supplies with different output levels in hybrid and electric vehicles in both their isolated and non-isolated versions. The emerging idea is to use one controllable switch to avoid synchronisation problem among switches. A key challenge lies in modeling the SIMO converters due to its differential algebraic nature and increased state-space dimension. This work proposes a port-Hamiltonian approach for modeling the SIMO converters. Controller design involves both current and voltage control of non-isolated SIMO converters in order to achieve largesignal stability and steady-state accuracy of multiple outputs. Simulations are performed on a DC-DC SEPIC-Boost converter to compare the time-domain and the frequency-domain responses of the states in the proposed model w.r.t. the actual circuit model. The response of the converter to large variations in the load is also simulated.",

The key idea is to modify the physical energy function of the system into a time-varying or nonsmooth one.

A brief survey on this topic is given with an emphasis on its extension to output feedback control which is one of the main advantages of the proposed passivity based approach.",

The control design is tailored to the Bionic Handling Assistant, a continuum mechanic robot developed by the Festo AG. As in many real-world applications, the control design for the BHA system requires to address non-linearities and robustness issues. In this work, we aim to provide a constructive robust control design for the BHA system, which can be readily adapted to similar continuum robotic manipulators. We develop a controller with an integral action to enhance the robustness of the control system and to compensate for disturbances.",

Based on energy aspect, the full order Unknown Input Hamiltonian Observer (UIHO) design scheme guarantees robust residual generation through decoupling the disturbances effects from the fault ones. The fault estimation is, then, allowed by an algebraic transformation taking into account co-energy variables. Finally, simulation tests on ladder networks illustrate the effectiveness of the theoretical development.",

However, robustness enhancement of this control approach towards external disturbances remains an challenging and an open problem. In this paper, an experimental comparative study between two different IDA-PBC approaches is proposed. The first controller is a nonlinear Proportional Integral IDA-PBC, while the second one is a model reference adaptive IDA - PBC. To evaluate the effectiveness of both controllers, various real-time experimental scenarios have been conducted for the stabilization of the inertia wheel inverted pendulum. For the sake of a fair comparison, different performance-evaluation criteria have been proposed to quantify the control performance in terms of convergence and energy consumption. The results show a better performance of the nonlinear Proportional Integral IDA - PBC controller compared to the model reference adaptive IDA - PBC controller.",

Owing to energetic and structural aspects, the generic model is competent to deduct immediately the energetic redundancy relations by covering the causal energetic paths. The performances of the suggested scheme is proved by the simulation results on the DC motor.",

      "abstract": "The major problem of controlling a multi-variable electrical system comes mainly from the lack of information on its structure, which was supposed to always linear, a change in unexpected state may cause system instability, hence the requirement development of a new control structure incorporating nonlinear effects and time-varying phenomena while respecting the desired specifications on their stabilities. A new control scheme for speed induction motors is proposed in the present paper, called \"passivity based control (PBC) on the principle of exchange control energy via state feedback was presented it allows to work in several areas. A port-controlled Hamiltonian (PCH) model of the induction motor is deduced to make the interconnection and damping of energy explicit on the scheme. The proposed controller is validated under computational simulations MATLAB.",

      "abstract": "We provide a solution to the long-standing problem of transient stabilization of multimachine power systems with nonnegligible transfer conductances. More specifically, we consider the full 3n-dimensional model of the n-generator system with lossy transmission lines and loads and prove the existence of a nonlinear static state feedback law for the generator excitation field that ensures asymptotic stability of the operating point with a well-defined estimate of the domain of attraction provided by a bona fide Lyapunov function. To design the control law we apply the recently introduced interconnection and damping assignment passivity-based control methodology that endows the closed-loop system with a port-controlled Hamiltonian structure with desired total energy function. The latter consists of terms akin to kinetic and potential energies, thus has a clear physical interpretation. Our derivations underscore the deleterious effects of resistive elements which, as is well known, hamper the assignment of simple \"gradient\" energy functions and compel us to include nonstandard cross terms. A key step in the construction is the modification of the energy transfer between the electrical and the mechanical parts of the system which is obtained via the introduction of state-modulated interconnections that play the role of multipliers in classical passivity theory.",

      "abstract": "In this note, the regulation problem for mixed finite and infinite dimensional port Hamiltonian systems (m-pH systems) is discussed. A m-pH system results from the power conserving interconnection of finite and infinite dimensional systems in port Hamiltonian form. In particular, the system given by the interconnection of two finite dimensional systems, one of which is the controller, by means of an infinite dimensional connection is studied. The proposed control methodology is a generalization to the infinite dimensional case of a well-established passivity-based control technique for finite-dimensional port Hamiltonian systems, the control by interconnection and energy shaping, according to which the open-loop energy function is shaped so that a minimum in the desired configuration is introduced. This procedure is possible once the state variable of the controller is related to the state variable of the plant by constraining the state of the closed-loop system on a structural invariant (defined by a set of Casimir functions). In this way, the energy function of the controller, which is freely assignable, becomes a function of the configuration of the plant and, then, it can be easily shaped in order to solve the regulation problem.",

      "abstract": "The dynamics of many physical processes can be suitably described by Port-Hamiltonian (PH) models, where the importance of the energy function, the interconnection pattern and the dissipation of the system is underscored. To regulate the behavior of PH systems it is natural to adopt a Passivity-Based Control (PBC) perspective, where the control objectives are achieved shaping the energy function and adding dissipation. In this paper we consider the PBC techniques of Control by Interconnection (CbI) and Standard PBC. In CbI the controller is another PH system connected to the plant (through a power-preserving interconnection) to add up their energy functions, while in Standard PBC energy shaping is achieved via static state feedback. In spite of the conceptual appeal of formulating the control problem as the interaction of dynamical systems, the current version of CbI imposes a severe restriction on the plant dissipation structure that stymies its practical application. On the other hand, Standard PBC, which is usually derived from a uninspiring and non-intuitive ldquopassive output generationrdquo viewpoint, is one of the most successful controller design techniques. The main objectives of this paper are: (1) To extend the CbI method to make it more widely applicable-in particular, to overcome the aforementioned dissipation obstacle. (2) To show that various popular variants of Standard PBC can be derived proceeding from a unified perspective. (3) To establish the connections between CbI and Standard PBC proving that the latter is obtained restricting the former to a suitable subset-providing a nice geometric interpretation to Standard PBC-and comparing the size of the set of PH plants for which they are applicable.",

For this class of systems we provide simple tools to check exponential stability. This class is general enough to include models of flexible structures, traveling waves, heat exchangers, and bioreactors among others. The result is based on the use of a generating function (the energy for physical systems) and an inequality condition at the boundary. Furthermore, based on the port Hamiltonian approach, we give a constructive method to reduce this inequality to a simple matrix inequality.",

      "abstract": "The dynamics of open irreversible thermodynamic systems, that is systems including both the balance equation of the energy and the entropy, has been formulated as contact vector fields with generating functions depending on some external (control) variable and called conservative port contact systems. In this paper we relate the dynamical properties of these systems (equilibrium points, asymptotic stability) to properties of the generating functions (the contact Hamiltonian functions). We show that the equilibrium points of the system satisfy certain conditions involving the contact Hamiltonian function. We also consider Lyapunov's first theorem to emphasize a stability criterion for the equilibrium points in terms of this contact Hamiltonian function and relate it to some thermodynamical properties. These results are then related to the physical phenomena that are taking place in the system.",

Furthermore, it is shown how the rational Lanczos method applied to a subclass of port-Hamiltonian systems, characterized by an algebraic condition, preserves the port-Hamiltonian structure. In fact, for the same subclass of port-Hamiltonian systems the rational Arnoldi method and the rational Lanczos method turn out to be equivalent in the sense of producing reduced order port-Hamiltonian models with the same transfer function.",

Adaptive control is used to compensate for control errors that are caused by unknown or uncertain parameter values of a system. The adaptive control is also combined with canonical transformation theory for port-Hamiltonian systems. This allows for the adaptive control to be applied on a large class of systems and for being included in the port-Hamiltonian framework.",

      "abstract": "This paper introduces stochastic port-Hamiltonian systems and clarifies some of their properties. Stochastic port-Hamiltonian systems are extension of port-Hamiltonian systems which are used to express various deterministic passive systems. Some properties such as passivity of port-Hamiltonian systems do not generally hold for the stochastic port-Hamiltonian systems. Firstly, we show a necessary and sufficient condition to preserve the stochastic Hamiltonian structure of the original system under time-invariant coordinate transformations. Secondly, we derive a condition to maintain stochastic passivity of the system. Finally, we introduce stochastic generalized canonical transformations and propose a stabilization method based on stochastic passivity.",

In contrast to the well-established representation relying on Stokes-Dirac structures that are based on skew-adjoint differential operators and the use of energy variables, we employ a different port-Hamiltonian framework. Based on this system representation conditions for Casimir functionals will be derived where in this context the variational derivative plays an extraordinary role. Furthermore the coupling of finite- and infinite-dimensional systems will be analyzed in the spirit of the control by interconnection problem.",

This follows since the controller imposes exponential dissipation of the total energy. The result can by use for control synthesis and for the stability analysis of complex systems modeled by sets of coupled PDE's and ODE's. The result is specialized to port-Hamiltonian control systems and a simplified DNA-manipulation process is used to illustrate the result.",

The proposed controller is obtained combining a recently reported exponentially stable immersion and invariance observer and a suitably designed state-feedback passivity-based controller, which assigns to the closed-loop a port-Hamiltonian structure with a desired energy function. The result is applicable to a large class of mechanical systems and, in particular, no assumptions are made on the presence-and exact knowledge-of friction forces.",

      "abstract": "Many powerful tools exist for control design in the frequency domain, but are theoretically only justified for linear systems. On the other hand, nonlinear control deals with control design methodologies that are theoretically justified for a larger and more realistic class of systems, but primarily dealing with stability and to a lesser extent with performance. In this technical note a standard linear notch filter is modeled in the port-Hamiltonian (PH) framework, thereby proving that the notch filter is a passive system. The notch filter can then be interconnected with any other (nonlinear) PH system, while preserving the overall passivity property. By doing so, we can combine a frequency-based control method to improve performance, the notch filter, with the nonlinear control methodology of passivity-based control.",

      "abstract": "The Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) problem for port-controlled Hamiltonian systems is revisited. We propose a methodology that exploits the novel notion of algebraic solution of the so-called matching equation. This notion is instrumental for the construction of an energy function, defined on an extended state-space, which does not rely upon the solution of any partial differential equation. This yields, differently from the classical solution, a dynamic state feedback that stabilizes a desired equilibrium point. In addition, conditions that allow to preserve the port-controlled Hamiltonian structure in the extended closed-loop system are provided. The theory is validated on two physical systems: the magnetic levitated ball and a third order food-chain system. A dynamic control law is constructed for both these systems by assigning a damping factor that cannot be assigned by the classical IDA-PBC.",

      "abstract": "Port-Hamiltonian (PH) theory is a novel, but well established modeling framework for nonlinear physical systems. Due to the emphasis on the physical structure and modular framework, PH modeling has become a prime focus in system theory. This has led to a considerable research interest in the control of PH systems, resulting in numerous nonlinear control techniques. General nonlinear control methodologies are classified in a spectrum from model-based to model-free, where adaptation and learning typically lie close to the end of the range. Various articles and monographs have provided a detailed overview of model-based control techniques on PH models, but no survey is specifically dedicated to the learning and adaptive control methods that can benefit from the PH structure. To this end, we provide a comprehensive review of the current learning and adaptive control methodologies that have been adapted specifically to PH systems. After establishing the required theoretical background, we elaborate on various general machine learning, iterative learning, and adaptive control techniques and their application to PH systems. For each method we highlight the changes from the general setting due to PH model, followed by a detailed presentation of the respective control algorithm. In general, the advantages of using PH models in learning and adaptive controllers are: i) Prior knowledge in the form of PH model speeds up the learning. ii) In some instances new stability or convergence guarantees are obtained by having a PH model. iii) The resulting control laws can be interpreted in the context of physical systems. We conclude the paper with notes on open research issues.",

      "abstract": "This technical note presents an integrated approach for formation control and velocity tracking of a group of nonholonomic wheeled robots. The solution is defined within the port-Hamiltonian framework, providing a clear interpretation of the results. The controller consists of a local nonlinear heading and velocity tracking controller combined with a distributed formation controller. The formation controller achieves formations by assigning virtual couplings in between the robots. Experimental results are provided to illustrate the effectiveness of the approach.",

      "abstract": "This paper is concerned with the energy shaping of 1-D linear boundary controlled port-Hamiltonian systems. The energy-Casimir method is first proposed to deal with power preserving systems. It is shown how to use finite dimensional dynamic boundary controllers and closed-loop structural invariants to partially shape the closed-loop energy function and how such controller finally reduces to a state feedback. When dissipative port-Hamiltonian systems are considered, the Casimir functions do not exist anymore (dissipation obstacle) and the immersion (via a dynamic controller)/reduction (through invariants) method cannot be applied. The main contribution of this paper is to show how to use the same ideas and state functions to shape the closed-loop energy function of dissipative systems through direct state feedback i.e. without relying on a dynamic controller and a reduction step. In both cases, the existence of solution and the asymptotic stability (by additional damping injection) of the closed-loop system are proven. The general theory and achievable closed-loop performances are illustrated with the help of a concluding example, the boundary stabilization of a longitudinal beam vibrations.",

      "abstract": "In this paper, a unifying energy-based approach is provided to the modeling and stability analysis of power systems coupled with market dynamics. We consider a standard model of the power network with a third-order model for the synchronous generators involving voltage dynamics. By applying the primal-dual gradient method to a social welfare optimization, a distributed dynamic pricing algorithm is obtained, which can be naturally formulated in port-Hamiltonian form. By interconnection with the physical model a closed-loop port-Hamiltonian system is obtained, whose properties are exploited to prove asymptotic stability to the set of optimal points. This result is extended to the case that also general nodal power constraints are included into the social welfare problem. Additionally, the case of line congestion and power transmission costs in acyclic networks is covered. Finally, a dynamic pricing algorithm is proposed that does not require knowledge about the power supply and demand.",

      "abstract": "It is a universal phenomenon that the inputs of a real stochastic process are disturbed. However, this phenomenon is often ignored when stochastic port-Hamiltonian system (SPHS) is used for modeling, in which only the disturbance on the states is considered. For this reason, an extension of SPHS, named input-disturbed SPHS (Id-SPHS), is proposed to describe the inputs disturbance as well as the states one. The definition and some properties of Id-SPHS, including structure invariance and stochastic passivity, are presented one by one to construct the basic framework of Id-SPHS. Based on this framework, a passivity-based controller is further developed to stabilize Id-SPHS at its steady state. The control strategy is demonstrated in a thermodynamic heat conduction process with the results supporting strongly the proposed Id-SPHS theory.",

      "abstract": "In this paper we present a method for the addition of integral action to nonpassive outputs of a class of port-Hamiltonian (pH) systems. The proposed integral controller is a dynamic extension, constructed from the open-loop system, such that the closed loop preserves the pH form. It is shown that the controller is able to reject the effects of both matched and unmatched disturbances, preserving the regulation of the nonpassive outputs. Previous solutions to this problem have relied on a change of coordinates whereas the presented solution is developed using the original state vector and, therefore, retains its physical interpretation. In addition, the resulting closed-loop dynamics have a natural interpretation as a control by interconnection scheme.",

The controller design problems are formulated as optimization problems on the product manifold of the set of skew symmetric matrices, the manifold of the symmetric positive definite matrices, and Euclidean space. A Riemannian metric is chosen for the manifold in such a manner that the manifold is geodesically complete, i.e., the domain of the exponential map is the whole tangent space for every point on the manifold. In order to solve these problems, the Riemannian gradients of the objective functions are derived, and these gradients are used to develop a Riemannian steepest descent method on the product manifold. The geodesic completeness of the manifold guarantees that all points generated by the steepest descent method are on the manifold. Numerical experiments illustrate that our method is able to solve the two specified problems.",

      "abstract": "In this note, we address the problem of stabilization of <italic>port-Hamiltonian</italic> systems via the ubiquitous proportional-integral-derivative (PID) controller. The design is based on passivity theory, hence the first step is to identify <italic>all passive outputs</italic> of the system, which is the first contribution of the paper. Adding a PID around this signal ensures that the closed-loop system is ${\\mathcal L}_2$-stable for <italic>all</italic> positive PID gains. Global stability (and/or global attractivity) of a desired <italic>constant equilibrium</italic> is also guaranteed for a new class of systems for which a Lyapunov function can be constructed. A second contribution is to prove that this class—that is identified via some easily verifiable integrability conditions—is strictly larger than the ones previously reported in the literature. Comparisons of the proposed PID controller with control-by-interconnection passivity-based control are also discussed.",

      "abstract": "Interconnection and damping assignment passivity-based control (IDA-PBC) is a method that has been developed to (asymptotically) stabilize nonlinear systems formulated in the port-controlled Hamiltonian (PCH) structure. This method has gained increasing popularity and has been successfully applied to a wide range of dynamical systems. However, little is known about the robustness of this method in response to the effects of uncertainty which could result from disturbances, noises, and modeling errors. This paper explores the possibility of extending some energy shaping methods, taking into account the robustness aspects, with the aim of maintaining (asymptotic) stability of the system in the presence of perturbations which inevitably exist in any realistic applications. We propose constructive results on robust IDA-PBC controllers for underactuated mechanical systems that are quite commonly found in practice and have the most challenging control problems within this context. The proposed results extend some existing methods and provide a new framework that allows the implementation of integral and input-to-state stability controllers to underactuated mechanical systems. The results are applied to two physical systems: an inertia wheel pendulum and a rotary inverted pendulum that represent separable and nonseparable PCH systems, respectively.",

      "abstract": "In this paper, a full-order observer design method is proposed for port-Hamiltonian systems. The proposed method is based on the notion of contractive port-Hamiltonian systems. It is the first structure preserving observer design for a broad class of input-state-output port-Hamiltonian systems. The design procedure consists of solving a matching equation, similar to the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) for controller design. The matching equation, as shown in the paper, has some closed-form solutions for general class of mechanical and electromechanical systems. As another feature of the proposed method, it is shown that the existence of solution of the corresponding matching equation for a linear port-Hamiltonian system is equivalent to the detectability property of that system. Upon these facts, the proposed method can be considered as a counterpart of IDA-PBC for observer design. Simulations for some benchmark examples, including ball and beam, magnetic levitation, and permanent magnetic synchronous motor, show the potency and applicability of the method.",

      "abstract": "In this paper, the locally fixed-time and globally fixed-time $\\mathcal {H}_{\\infty }$ control problems for the port-controlled Hamiltonian (PCH) systems are investigated via the interconnection and damping assignment passivity-based control (IDA-PBC) technique. Compared with finite-time stabilization, where the convergence time of the closed-loop system's states relies on the initial values, the settling time of fixed-time stabilization can be adjusted to achieve desired equilibrium point regardless of initial conditions. The concepts of fixed-time $\\mathcal {H}_{\\infty }$ control, fixed-time stability region (or region of attraction), and fixed-time stability boundary are presented in this paper, and the criterions of globally fixed-time attractivity of a prespecified locally fixed-time stability region are obtained. Combining the locally fixed-time stability of an equilibrium point and the globally fixed-time attractivity of a prespecified fixed-time stability region, the globally fixed-time $\\mathcal {H}_{\\infty }$ control problem of PCH system is effectively solved. Two novel control laws are designed to deal with the globally fixed-time $\\mathcal {H}_{\\infty }$ control problem, and the conservativeness in estimating the settling time is also briefly discussed. An illustrative example shows that the theoretical results obtained in this paper work very well in the fixed-time $\\mathcal {H}_{\\infty }$ control design for PCH systems.",

      "abstract": "In this paper, we present a method to robustify asymptotically stable nonlinear systems by adding an integral action that rejects unknown additive disturbances. The proposed approach uses a port-Hamiltonian (pH) representation of the open-loop dynamics, which, relying on the asymptotic stability property, is guaranteed to exist. The integral action controller preserves the pH structure, and, by adding a suitable cross term between the plant and the controller states to the closed-loop energy function, it avoids the unnatural coordinate transformation used in the past. The controller is shown to be robust against some common types of modeling uncertainty, including unknown friction dynamics in mechanical systems.",

They are an extension of SPHSs defined on a finite-dimensional state space. The concept of well-posedness in the sense of Weiss and Salamon is generalized to the stochastic context. Under this extended definition, SPHSs are shown to be well posed. The theory is illustrated on an example of a vibrating string subject to a Hilbert space-valued Gaussian white noise process.",

      "abstract": "In this article, we give easily verifiable sufficient conditions for two classes of perturbed linear, passive partial differential equation (PDE) systems to be well-posed, and we provide an energy inequality for the perturbed systems. Our conditions are in terms of smoothness of the operator functions that describe the multiplicative and additive perturbations, and here, well-posedness essentially means that the time-varying systems have strongly continuous Lax–Phillips evolution families. A time-varying wave equation with a bounded multidimensional Lipschitz domain is used as illustration, and as a part of the example, we show that the time-invariant wave equation is a “physically motivated” scattering-passive system in the sense of Staffans and Weiss. The theory also applies to time-varying port-Hamiltonian systems.",

      "abstract": "In this article, we present some new results for the design of PID passivity-based controllers (PBCs) for the regulation of port-Hamiltonian (pH) systems. The main contributions of this article are: (i) new algebraic conditions for the explicit solution of the partial differential equation required in this design; (ii) revealing the deleterious impact of the dissipation obstacle that limits the application of the standard PID-PBC to systems without pervasive dissipation; (iii) the proposal of a new PID-PBC which is generated by two passive outputs, one with relative degree zero and the other with relative degree one. The first output ensures that the PID-PBC is not hindered by the dissipation obstacle, while the relative degree of the second passive output allows the inclusion of a derivative term. Making the procedure more constructive and removing the requirement on the dissipation significantly extends the realm of application of PID-PBC. Moreover, allowing the possibility of adding a derivative term to the control, enhances its transient performance.",

      "abstract": "This article proposes a method that combines linear quadratic Gaussian (LQG) control design and structure preserving model reduction for the reduced order control of infinite dimensional port Hamiltonian systems (IDPHS).For that purpose the weighting operators used in LQG control design are chosen such that the resulting dynamic controller is passive and the closed-loop system equivalent to control by interconnection. The method of Petrov–Galerkin is then used to approximate the balanced realization of the IDPHS by a finite dimensional port Hamiltonian system and to provide the associated reduced order LQG controller. The main advantages of the proposed method are that, first, both control and reduction are driven by closed-loop performances and that, second, due to the passivity properties of the controller the closed-loop stability is guaranteed when the finite dimensional controller is applied to the infinite dimensional system.",

Starting from a first feedback loop that is in charge of modifying the Hamiltonian function of the plant, a second control loop that guarantees exponential convergence to the equilibrium is designed. In this way, a major limitation of standard energy shaping plus damping injection control laws applied to linear port-Hamiltonian BCSs, namely the fact that only asymptotic convergence is assured, has been removed.",

      "abstract": "In this article, stabilization of port-Hamiltonian (pH) systems is studied in the context of shifted passivity. The pH systems, in general, are not shifted passive with respect to the given Hamiltonian and output. Therefore, we consider enforcing the property of shifted passivity by designing a state feedback, namely, shifted passivity via feedback. This introduced concept brings more insight into the stabilization of pH systems, and a set of partial differential equations is derived such that its solution specifies a state feedback achieving shifted passivity via feedback. Based on the framework of shifted passivity via feedback, a group of sufficient conditions is given such that a proposed proportional control with respect to a designed power shaping output can achieve closed-loop asymptotic stability. Some extended control design is provided to relax the required conditions.",

      "abstract": "In this article, a control framework is proposed to render a power electronic system passive by adopting the port-Hamiltonian (pH) systems theory. The system has a power electronic converter, either grid-tied or islanded. The control framework consists of a lossless interconnection block and three control channels. It makes the power converter behave as a virtual synchronous machine (VSM). The three channels are designed to, respectively, generate the frequency and the flux of the VSM and a third quantity that is necessary for forming the lossless interconnection. It is proven that the closed-loop system is passive without the need of assuming constant frequency, constant voltage, and/or constant loads. It is sufficient to only assume that the load can be described as a passive pH model. Hence, the proposed control framework is very generic.",

The control design is achieved using the internal model principle and the stability analysis using a Lyapunov approach. Contrary to existing works on the same topic, no assumption is made on the external well-posedness of the considered class of PDEs. The results are applied to robust tracking of a piezo actuated tube used in atomic force imaging.",

      "abstract": "The Second Law of thermodynamics implies that no thermodynamic system with a single heat source at constant temperature can convert heat into mechanical work in a recurrent manner. First, we note that this is equivalent to cyclo-passivity at the mechanical port of the thermodynamic system, while the temperature at the thermal port of the system is kept constant. This leads to the question, which general systems with two power ports have similar behavior: when is a system cyclo-passive at one of its ports, while the output variable at the other port (such as the temperature in the thermodynamic case) is kept constant? This property is called “one-port cyclo-passivity,” and entails, whenever it holds, a fundamental limitation to energy transfer from one port to the other. Sufficient conditions for one-port cyclo-passivity are derived for general multiphysics systems formulated in port-Hamiltonian form. This is illustrated by a variety of examples from different (multi-)physical domains; from coupled inductors and capacitor microphones to synchronous machines.",

      "abstract": "In this article, we treat extended balancing for continuous-time linear time-invariant systems. We take a dissipativity perspective, thus, resulting in a characterization in terms of linear matrix inequalities. This perspective is useful for determining a priori error bounds. In addition, we address the problem of structure-preserving model reduction of the subclass of port-Hamiltonian systems. We establish sufficient conditions to ensure that the reduced-order model preserves a port-Hamiltonian structure. Moreover, we show that the use of extended Gramians can be exploited to get a small error bound and, possibly, to preserve a physical interpretation for the reduced-order model. We illustrate the results with a large-scale mechanical system example. Furthermore, we show how to interpret a reduced-order model of an electrical circuit again as a lower dimensional electrical circuit.",

      "abstract": "This article investigates the transformation of Hamiltonian structures under sampling. It is shown that the exact sampled equivalent model associated to a given port-Hamiltonian continuous-time dynamics exhibits a discrete-time representation in terms of the discrete gradient, with the same energy function but modified damping and interconnection matrices. By construction, the proposed sampled-data dynamics guarantees exact matching of both the state evolutions and the energy-balance at all sampling instants. Its generalization to port-controlled Hamiltonian dynamics leads to characterize a new power conjugate output so recovering the concept of average passivation. On these bases, energy-management control strategies can be proposed. An energetic interpretation of the approach is confirmed by its formulation in the Dirac formalism. Two classical examples are worked out to validate the proposed sampled-data modeling in a comparative way with the literature.",

      "abstract": "The design of an observer-based state feedback controller with guaranteed passivity properties for port-Hamiltonian systems (PHS) is addressed using linear matrix inequalities (LMIs). The observer gain is freely chosen and the LMIs conditions such that the state feedback is equivalent to control by interconnection with an input strictly passive and/or an output strictly passive and zero-state detectable port-Hamiltonian controller are established. It is shown that the proposed controller exponentially stabilizes a class of infinite-dimensional PHS and asymptotically stabilizes a class of finite-dimensional nonlinear PHS. A Timoshenko beam model and a microelectromechanical system are used to illustrate the proposed approach.",

      "abstract": "This note proposes a passivity-based control method for trajectory tracking and formation control of nonholonomic wheeled robots without velocity measurements. Coordinate transformations are used to incorporate the nonholonomic constraints, which are then avoided by controlling the front end of the robot rather than the center of the wheel axle into the differential equations. Starting from the passivity-based coordination design, the control goals are achieved via an internal controller for velocity tracking and heading control, and an external controller for formation in the port-Hamiltonian framework. This approach endows the resulting controller with a physical interpretation. To avoid unavailable velocity measurements or unreliable velocity estimations, we derive the distributed control law with only position measurements by introducing a dynamic extension. In addition, we prove that our approach is suitable not only for acyclic graphs but also for a class of nonacyclic graphs, namely, ring graphs. Simulations are provided to illustrate the effectiveness of the approach.",

      "abstract": "A control system is called self-powered if the only energy it requires for operation is that which it absorbs from the plant. For a linear feedback law to be feasible for a self-powered control system, its feedback signal must be colocated with the control inputs, and its input–output mapping must satisfy an associated passivity constraint. The imposition of such a feedback law can be viewed equivalently as the imposition of a linear passive shunt admittance at the actuation ports of the plant. In this article, we consider the use of actively-controlled electronics to impose a self-powered linear feedback law. To be feasible, it is insufficient that the imposed admittance be passive, because parasitic losses must additionally be overcome. We derive sufficient feasibility conditions, which explicitly account for these losses. In the finite-dimensional, time-invariant case, the feasibility condition distills to a more conservative version of the positive-real lemma, which is parametrized by various loss parameters. Three examples are given, in which this condition is used to determine the least-efficient loss parameters necessary to realize a desired feedback law.",

      "abstract": "In this article, for the input-state-output class of port-Hamiltonian systems, the contraction property is characterized. Recently, some results on contraction of port-Hamiltonian systems with constant interconnection and damping matrices have been published. This article extends these results for state-modulated interconnection and damping matrices. In this regard, the powerful method of interconnection and damping assignment passivity-based control is extended for tracking designs. Controller design for underactuated mechanical systems with nonconstant mass matrices usually leads to nonconstant (state-modulated) interconnection and damping matrices for the closed-loop system. Therefore, the result of this article can be used for tracking controller design for underactuated mechanical systems. To show the potency of proposed results, a tracking controller for cart–pole system is designed and simulated.",

      "abstract": "This article aims at extending the continuous-time energy-shaping plus damping injection control design technique to deal with a class of nonlinear, discrete-time port-Hamiltonian systems. For such systems, the gradient of the Hamiltonian function in the continuous-time dynamics is replaced by a discrete gradient, thus leading to a state equation in implicit form. Its well-posedness is studied both in the autonomous and nonautonomous cases to determine when the dynamical equation admits a solution for the next state. Based on this analysis, the extension of the energy-shaping plus damping injection control methodology is discussed. At first, it is supposed that the control action depends on the discrete gradient of an energy function. Then, this hypothesis is removed, and an algebraic solution to the matching equation is proposed to enlarge the class of stabilizing controllers.",

With the help of the port-Hamiltonian framework, we first prove the existence of solutions and show, by the use of an appropriate Lyapunov function, that the system is exponentially stable and has an explicit decay rate. The explicit exponential bound is computed for an illustrative example for which we provide some numerical simulations.",

The characterization of the underlying Dirac structure depends on separating the stored energy associated with the system into two distinct components. Moreover, it is shown that power-preserving interconnection and negative output feedback maintain the port-Hamiltonian structure while increasing the dimension of the Dirac structure. Finally, the proposed approach is illustrated by means of an approximated gravity pendulum model.",

      "abstract": "In this article, we propose a new frequency-limited Riemannian geometric-nonlinear conjugate gradient model order reduction (MOR) method with the modified Armijo step-size control to solve the frequency-limited $\\mathcal {H}_{2}$ optimal MOR problem of linear port-Hamiltonian systems. This problem is formulated as a Riemannian optimization problem on the product of several manifolds. Based on the geometric properties of the product manifold, the Riemannian gradient of the cost function is derived. Further, by scaling the vector transport of the product manifold, we design a new Riemannian spectral conjugate gradient direction, which is always descent for the cost function and is independent of the line search used and the convexity of the cost function. Meanwhile, a new modified Armijo step-size control strategy is presented. The resulting reduced system can preserve the port-Hamiltonian structure and the passivity of the original system. Two numerical examples are simulated to demonstrate the efficiency of the proposed method.",

      "abstract": "In this work, the multiplier method is extended to obtain a general lower bound on the exponential decay rate for port-Hamiltonian systems in one space dimension with boundary dissipation. The physical parameters of the system may be spatially varying. It is shown that, under assumptions of boundary or internal dissipation, the system is exponentially stable. This is established through a Lyapunov function defined through a general multiplier function. Furthermore, an explicit bound on the decay rate in terms of the physical parameters is obtained. The method is applied to a number of examples.",

Very recently, Jacob and Laasri obtained strong results on the solvability and well-posedness of time-varying linear port-Hamiltonian systems with boundary control and boundary observation. In this article, we complement their results by discussing the solvability of linear, infinite-dimensional time-varying port-Hamiltonian systems not necessarily of boundary control type. The theory is illustrated on a system with a delay component in the state dynamics.",

      "abstract": "In this work, we propose a new passivity-based sliding mode control (PBSMC) method for mechanical port-Hamiltonian systems. PBSMC is unification of sliding mode control and passivity-based control. It achieves sliding mode control and Lyapunov stability simultaneously by employing an energy-based Lyapunov function. The proposed method gives a family of stabilizing controllers that smoothly interpolates passivity-based control and sliding mode control with design parameters. The freedom is useful to adjust the tradeoff between robustness against external disturbances and undesired chattering vibration. In addition, this article relaxes the restrictive condition, which is required in the authors' former result. As a result, we can apply the proposed PBSMC method to trajectory tracking control problems. Furthermore, the robustness of the proposed controller against matched and unmatched disturbances is investigated. Numerical examples demonstrate the effectiveness of the proposed method.",

Our definition of a delay pH system is motivated by investigating the Kalman–Yakubovich–Popov inequality on the corresponding infinite-dimensional operator equation. Moreover, we show that delay pH systems are passive and closed under interconnection. We describe an explicit way to construct a Lyapunov–Krasovskii functional and discuss implications for delayed feedback.",

      "abstract": "Passive systems are characterized by their inability to generate energy internally, providing a powerful tool for modeling physical phenomena. In addition, algebraically encoding passivity in the system description can be advantageous. For this, port-Hamiltonian systems are a prominent approach. Another possibility is writing the system in suitable coordinates. In this article, we investigate the equivalence between passivity and the feasibility of passivity encoding representations, thereby elaborating upon existing results for port-Hamiltonian systems. Based on our findings, we present a method to construct port-Hamiltonian representations of a passive system if the dynamics and the Hamiltonian are known.",

      "abstract": "This article presents a design framework of discrete-time regulators for linear port-Hamiltonian boundary control systems. The contribution is twofold. At first, a discrete-time approximation of the plant dynamics originally described by a linear partial differential equation with boundary actuation is introduced. The discretization is performed in time only. Thus, the “distributed nature” of the state is maintained. Such a system inherits the passivity of the original one and is well-posed, i.e., the “next” state always exists. In the second part, instead, the control design problem is tackled. Initially, the characterization of discrete-time, linear controllers in the port-Hamiltonian form that render the closed-loop dynamics asymptotically stable is presented. Then, the control by energy-shaping and damping injection paradigm is extended to deal with this novel class of distributed-parameter systems. A numerical example illustrates the effectiveness of the proposed framework.",

      "abstract": "In this article, we present a distributed control system design for the consensus of nonlinear multiagent systems subject to non-ideal communication channels and external disturbances. The agents are modeled as a class of perturbed port-Hamiltonian systems—a formalism to model complex physical and engineering systems—and the imperfection in the communication channels is represented by time-delays that are assumed to be bounded. We show that the proposed distributed controller ensures global asymptomatic convergence of the agents to a consensus equilibrium, despite external disturbances and time-delays. We also extend the results to Euler–Lagrange agents as a corollary of our main result. Simulation results, for a network of five, 2-degrees-of-freedom robotic manipulators show the performance of our proposed control design.",

      "abstract": "The design of suitablesliding manifolds remains one of the main bottlenecks in sliding mode control. This article proposes a strategy to address this problem for a broad class of nonlinear systems. To this end, we develop an original, systematic methodology to design stabilizing sliding manifolds for a class of nonlinear port-Hamiltonian (pH) systems. In particular, we exploit the pH structure of the system to design a sliding manifold, where the system preserves the desired passivity properties that are useful to stabilize the dynamics of the system on the designed manifold. The proposed modular control design offers significant advantages compared to the individual application of sliding mode control and passivity-based control techniques, effectively simplifying the design and enhancing robustness. Finally, the applicability of the proposed strategy is assessed via simulations.",

      "abstract": "The control of large-scale cyber-physical systems requires optimal distributed policies relying solely on limited communication with neighboring agents. However, computing stabilizing controllers for nonlinear systems while optimizing complex costs remains a significant challenge. Neural networks (NNs), known for their expressivity, can be leveraged to parameterize control policies that yield good performance. However, NNs' sensitivity to small input changes poses a risk of destabilizing the closed-loop system. Many existing approaches enforce constraints on the controllers' parameter space to guarantee closed-loop stability, leading to computationally expensive optimization procedures. To address these problems, we leverage the framework of port-Hamiltonian systems to design continuous-time distributed control policies for nonlinear systems that guarantee closed-loop stability and finite $\\mathcal {L}_{2}$ or incremental $\\mathcal {L}_{2}$ gains, independent of the optimization parameters of the controllers. This eliminates the need to constrain parameters during optimization, allowing the use of standard techniques such as gradient-based methods. In addition, we discuss discretization schemes that preserve the dissipation properties of these controllers for implementation on embedded systems. The effectiveness of the proposed distributed controllers is demonstrated through consensus control of nonholonomic mobile robots subject to collision avoidance and averaged voltage regulation with weighted power sharing in islanded DC microgrids.",

      "abstract": "In the future, drag-free satellites will be the key platform to detect gravitational waves in deep space. Due to the ambitious ultra-quiet-stable control requirements of such a mission, the system dynamics are quite complex and strongly nonlinear, which introduces challenges in the modeling and control of the spacecraft. Currently, drag-free controller designs focus on linearized systems and usually invoke linear control theory. These methods ignore the nonlinearities of the system and may cause instability in real applications. In this work, we first propose an energy-based method to model the drag-free system in the port-Hamiltonian framework. Then, a nonlinear drag-free controller with integral action is designed. It is proved that the achieved controller secures internal stability, rejection of unknown disturbances, and input-to-state stability. Finally, a numerical simulation is conducted to verify the theoretical results and the control performance.",

      "abstract": "The ondes Martenot is a classic electronic musical instrument based on heterodyning processing. This article proposes a power-balanced simulation of its circuit, in order to synthesize the sound it produces. To this end, the proposed approach consists in formulating the circuit as a Port-Hamiltonian System, for which power-balanced numerical methods are available. Observations on numerical experiments based upon this formulation allow simplifications of the circuit in order to achieve real-time computation in home-studio conditions.",

      "abstract": "In stand-alone photovoltaic (PV) power supply systems, due to daily and weather solar irradiation variability, special devices are used for energy storage, most often batteries. In order to remove stress from batteries during sudden load change, it is advisable to use hybrid energy storage systems (HESS), by adding a supercapacitor module to the battery. In this work, two battery/supercapacitor HESS configurations are investigated — active with two DC-DC converters and semi-active with one DC-DC convertor. Both HESSs are represented as port-controlled Hamiltonian systems, and the synthesis of energy-shaping control systems (ESCS) is carried out using the IDA-PBC method. As a result of the synthesis three structures of ESCSs were obtained. The conducted simulation studies in the Matlab/Simulink environment allowed us to justify the appropriate structures of the ESCSs for each of the HESSs configurations and showed that both systems satisfactorily fulfill management strategy. As a simpler and cheaper, the semi-active battery/supercapacitor HESS can be recommended for use in stand-alone PV installations.",

Two general cases are considered, when the system is i) linear time-invariant or ii) nonlinear, with dynamic behavior described by a port-Hamiltonian model with constant dissipation and switching interconnection matrix. The latter class includes the practically important case of power converters. For both cases necessary and sufficient conditions for existence of equilibria are given, which give an upper bound on the power dissipated in steady-state that should exceed the extracted constant power. The existence of the equilibrium is ensured if and only if the inequality is satisfied.",

      "abstract": "This paper deals with the frequency design of lossless passive electronic filters under magnitude constraints. With the huge increase in design complexity for mobile applications, new systematic and efficient methods are required. This paper focuses on the direct synthesis approach, an historical design approach that has not been recently updated. It consists in directly synthesizing the $LC$ values of a pre-specified circuit until the spectral mask is satisfied. While beneficial in practice, this approach typically leads to an important computational time and requires an initial guess to reduce it. Based on recent developments of the System and Control community, that led to efficient methods for system design, the direct synthesis approach is revisited. To achieve this, the port-Hamiltonian Differential Algebraic Equation (pHDAE) representation, that particularly fits the design problem, is introduced. A synthesis method is then developed, leading to solve an optimization problem of moderate complexity. For particular cases, this complexity happens to be remarkably low. Based on this observation, a second method reveals how to obtain such complexity for the more general case, using an original combination between the pHDAE and the LFT representations. Finally, a numerical example shows the validity and illustrates the benefits of this work.",

      "abstract": "This express brief presents a nonlinear active and reactive power control for a superconducting magnetic energy storage (SMES) system connected in three-phase distribution networks using pulse-width modulated current-source converter (PWM-CSC). The passivity-based control (PBC) theory is selected as a nonlinear control technique, since the open-loop dynamical model exhibits a port-Hamiltonian (pH) structure. The PBC theory exploits the pH structure of the open-loop dynamical system to design a general control law, which preserves the passive structure in closed-loop via interconnection and damping reassignment. Additionally, the PBC theory guarantees globally asymptotically stability in the sense of Lyapunov for the closed-loop dynamical system. Simulation results in a three-phase radial distribution network show the possibility to control the active and reactive power independently as well as the possibility to use the SMES system connected through a PWM-CSC as a dynamic power factor compensator for time-varying loads. All simulations are conducted in a MATLAB/ODE package.",

      "abstract": "Based on the Riemannian modified Fletcher–Reeves conjugate gradient scheme, we propose a new model order reduction algorithm to reduce port-Hamiltonian (PH) systems by the two-sided projection. Making full use of the geometric notions and geometrical characteristics of the Stiefel manifold, the proposed algorithm is not only computationally efficient, but also globally convergent. Additionally, it can preserve the PH structure and the passivity of the original system. A numerical example is simulated to demonstrate the efficiency of our algorithm.",

Specifically, by directed graphs, the general RLC circuits are firstly modeled as PH-DAE systems which imply the important passivity property. Based on $\\varepsilon $ -embedding and parametric moment matching techniques, MOR is implemented to the PH-DAE system, and the corresponding reduced system preserves PH-DAE structure and then preserves the passivity property. In addition, we prove that the reduced parametric PH system obtained by only one-side projection can preserve three times moments which indicates better accuracy in theory, and the error estimation between PH-DAE system and parametric PH system is also provided.",

      "abstract": "In this brief, the problem of voltage regulation of buck converter with a class of nonlinear loads is addressed by using an adaptive energy-based controller. It is noted that the existing results mainly cope with converters feeding one or several nonlinear loads. Other types of loads do exist in power systems. Therefore, based on the passivity theory and a coordinate transformation, this brief proposes a new energy-based controller to stabilize buck converter with a class of nonlinear loads. It is ensured that the closed-loop system is a port-Hamiltonian system with exponential convergence. Then, the estimated terms generated by a designed disturbance observer are forwarded to energy-based controller to reduce the influence of the time-varying disturbances on the system. The experiment test is conducted by means of the setup of buck converter with a constant power load. The simulation and experimental results verify the effectiveness of the designed controller.",

      "abstract": "This brief addressed the control design problem for a bilinear dynamical system with two approaches. The first approach is proportional-integral passivity-based control theory (PI-PBC), and the second control approach is based on inverse optimal control theory plus integral gain (IOC+I). PI-PBC theory is a well-known control design methodology for dealing with state variable regulation in dynamical systems that exhibit a port-Hamiltonian structure, with the main characteristic that a PI controller is designed by preserving the Hamiltonian properties in a closed loop while ensuring asymptotic stability. IOC+I allows for the design of feedback nonlinear controllers for dynamical systems, which in turn allows selecting the candidate Lyapunov function and the control matrix to obtain multiple nonlinear feedback controllers, with the main advantage that all of them ensure asymptotic stability, as the resulting control laws are optimal. This brief demonstrates that a PI-PBC design and IOC+I generate the same feedback control law if and only the candidate Lyapunov function of the IOC+I design is selected as the Hamiltonian function used in the PI-PBC design. The well-known three-phase front-end converter was selected as the test control system to demonstrate the equivalence between the control laws obtained with the PI-PBC and the IOC+I approaches.",

First, the closed-loop form of a time-varying PCH system (with certain feedback) is embedded into an extended system. Then by restricting the extended system to its invariant Casimir manifold, the energy function (Hamiltonian) of the original PCH system could be shaped as a candidate of Lyapunov function. Then the stabilization problem is considered by using the shaped Hamiltonian function. When the system has unknown parameters, the adaptive stabilization is considered, and the above stabilization result is used to construct an adaptive stabilizer. Finally, the method developed is used to power systems with periodic disturbances",

      "abstract": "In the last years the power-based modeling framework, developed in the sixties to model nonlinear electrical RLC networks, has been extended for modeling and control of a larger class of physical systems. In this brief we apply power-based integral control to a planar manipulator experimental setup. An integrator is known to compensate for steady-state errors, which usually occur in real applications. Recent developments in power-based control have shown the possibility of applying integral control to globally asymptotically stabilize a nonlinear system, without losing the original structure. In contrast, the more common PI or PID controllers do not provide such global properties. Both simulation and experimental results show an improvement in transient performance compared to PID control.",

      "abstract": "In a recent paper a procedure to design globally asymptotically stabilizing linear proportional plus integral controllers for switched power converters was proposed. The construction requires the measurement of the full state of the system, which is often unavailable in practice. In this note we identify a class of converters for which an asymptotically convergent reduced order observer, preserving the aforementioned stability property of the closed-loop, can be designed. The class is characterized by a simple linear matrix inequality. The new controller is illustrated with the widely-popular, and difficult to control, single-ended primary inductor converter, for which simulation and experimental results are presented.",

      "abstract": "In this brief, we address the robust force regulation problem of mechanical systems in physical interaction with compliant environments. The control method that we present is entirely derived under the energy shaping framework. Note that for compliant interactions, standard energy shaping methods (i.e., potential shaping controls using static-state feedback actions) cannot guarantee asymptotic stability since they are not robust to unmodeled forces. To cope with this issue, in this brief, we integrate force sensory feedback with a robust energy shaping design. This methodology allows us to incorporate integral force controls while preserving in closed loop the port-Hamiltonian structure, something that is not possible with traditional force regulators. We discuss the practical implementation of our method and provide simple numerical algorithms to compute in real time some of its control terms. To validate our approach, we report an experimental study with an open architecture robot manipulator.",

      "abstract": "This paper deals with the problem of achieving consensus of multiple Euler–Lagrange (EL) systems using the energy shaping plus damping injection principles of passivity-based control. It proposes a novel decentralized controller that is capable of solving the leaderless and the leader–follower consensus problems in networks of fully actuated EL-systems with interconnecting time-varying delays and without employing velocity measurements. This paper also presents a comparative simulation study with different controllers and provides experimental evidence of the performance of the novel controller.",

By means of a laboratory model, we address the classical problems modeling, flatness analysis, optimal trajectory planning, and feedback design. The main focus is on the efficient formulation of the trajectory planning problem as well as on a novel energy-based feedback methodology exploiting structural invariants (Casimir functionals). To solve the arising optimization problem, state-of-the-art software packages are utilized. Moreover, experimental results obtained from the laboratory model demonstrate the capability of the proposed feedforward and feedback methodology.",

      "abstract": "This paper presents an application of interconnection and damping assignment passivity-based control (IDA-PBC) principle to the port-controlled phasor Hamiltonian (PCPH) model of solid-state transformer (SST) (comprising of three stages, namely, ac/dc rectifier, dual active bridge converter, and dc/ac inverter). A PCPH model of SST is established for each individual stages using dynamic phasor concept. In comparison with other PBC approaches, IDA-PBC offers an additional degree of freedom to solve the partial differential equations. According to the target of the controller design at each stage, the desired equilibrium point of the system is obtained. The closed-loop system performance achieves regulation of constant output dc-bus voltage and unity input power factor. Large-signal simulation results for the full system validate the simplifications introduced to obtain the controller and verify the proposed controller. Robustness of the controller is demonstrated with 20% load disturbance and 10% input disturbance. For validation of the proposed approach and its effectiveness, hardware-in-loop simulation is carried out using Opal-RT and dSPACE simulators.",

      "abstract": "In this brief, we develop a mathematical model of a flexible spacecraft system composed of a hub and two symmetrical beams using the port-Hamiltonian framework. This class of system has favorable properties, such as passivity for controller synthesis and stability analysis, where the global Hamiltonian plays the role of a Lyapunov function candidate. The spacecraft model is viewed as a power-conserving interconnection between an infinite (beam) and finite (hub) dimensional system. We show that the interconnection result has a port-Hamiltonian structure and is passive. The introduction of a nonlinear feedback term, which takes into account the beam’s flexibility, is developed using the control by an interconnection approach. The closed-loop stability is proven; then, through explicitly solving the partial differential equations of the system, asymptotic stability is obtained. Finally, the experimental results are carried out to assess the validity of the proposed design methodology.",

      "abstract": "This brief addresses the problem of stabilizing steady, wing level flight of a fixed-wing aircraft to a specified inertial velocity (speed, course, and climb angle). The aircraft is modeled as a port-Hamiltonian system and the passivity of this system is leveraged in devising the nonlinear control law. The aerodynamic force model in the port-Hamiltonian formulation is quite general; the static, state feedback control scheme requires only basic assumptions concerning lift, side force, and drag. Following an energy-shaping approach, the static state feedback control law is designed to leverage the open-loop system’s port-Hamiltonian structure in order to construct a control Lyapunov function. Asymptotic stability of the desired flight condition is guaranteed within a large region of attraction. Simulations comparing the proposed flight controller with dynamic inversion suggest it is more robust to uncertainty in aerodynamics.",

      "abstract": "Voltage and frequency control in an islanded ac microgrid (ImG) amounts to stabilizing an a priori unknown ImG equilibrium induced by loads and changes in topology. This article puts forth a unified control framework, which, while guaranteeing such stability, allows for modular ImGs interconnecting multiple subsystems, that is, dynamic $RLC$ lines, nonlinear constant impedance, current, power (ZIP) and exponential (EXP) loads, and inverter-based distributed generation units (DGUs) controlled with different types of primary controllers. The underlying idea of the framework is based on the equilibrium-independent passivity (EIP) of the ImG subsystems, which enables stability certificates of ImG equilibria without explicit knowledge of these equilibria. In order to render DGUs EIP, we propose a decentralized controller synthesis algorithm based on port-Hamiltonian systems (PHSs). We also show that EIP, being the key to stability, provides a general framework, which can embrace other solutions available in the literature. Furthermore, we provide a novel argument based on LaSalle’s theorem for proving asymptotic voltage and frequency stability. Finally, we analyze the impact of actuator saturation on the stability results by exploiting the inherent EIP properties of the PHS DGU model. Theoretical findings are backed up by realistic simulations based on the medium-voltage CIGRE benchmark network.",

      "abstract": "This article provides a constructive passivity-based control (PBC) approach to solve the set-point regulation problem for input-affine continuous nonlinear systems while considering bounded inputs. As customary in PBC, the methodology consists of two steps: energy shaping and damping injection. In terms of applicability, the proposed controllers have two advantages concerning other PBC techniques: 1) the energy shaping is carried out without solving partial differential equations and 2) the damping injection is performed without measuring the passive output. As a result, the proposed methodology is suitable to control a broad range of physical systems, e.g., mechanical, electrical, and electromechanical systems, with saturated control signals. We illustrate the applicability of the technique by designing controllers for systems in different physical domains, where we validate the analytical results via simulations and experiments.",

      "abstract": "This article describes several approaches for tuning the parameters of a class of passivity-based controllers for standard nonlinear mechanical systems. In particular, we are interested in tuning controllers that preserve the mechanical system structure in the closed loop. To this end, first, we provide tuning rules for stabilization, i.e., the rate of convergence (exponential stability) and stability margin (input-to-state stability). Then, we provide guidelines to remove the overshoot. In addition, we propose a methodology to tune the gyroscopic-related parameters. We also provide remarks on the damping phenomenon to facilitate the practical implementation of our approaches. We conclude this article with experimental results obtained from applying our tuning rules to a fully actuated and an underactuated mechanical system.",

      "abstract": "This article introduces a novel control approach for tackling the maximum power point tracking (MPPT) and output voltage regulation (VR) in photovoltaic (PV) cell systems. Leveraging the port-Hamiltonian (pH) formalism, an energy-based framework known for its physically multidomain modeling and control methodologies, our proposed control law offers promising solutions. Our control design is rooted in an interconnection damping assignment passivity-based strategy, incorporating temperature dependencies of the internal PV cell parameters. To validate the efficacy of our approach, we modeled, implemented, and calibrated a prototype system comprising a PV cell, a dc–dc buck converter, and a dc–dc boost converter that feeds a battery load. The entire setup is designed within the pH framework, ensuring a cohesive integration of energy-based control. To highlight our energy-based strategy’s reliability and performance, we evaluated it against a commercial solar charger under real solar irradiance conditions. Our experimental findings unequivocally demonstrate that the control mechanism employed by the commercial solar charger demands a significantly higher amount of energy and exhibits a premature collapse at lower power levels when compared to our proposed system and control strategy.",

      "abstract": "This article proposes port-Hamiltonian (pH) stability analysis of synchronous reference frame-phase-locked loop (SRF-PLL) and double second-order generalized integrator-PLL (DSOGI-PLL) while accounting for the overlapping converter dynamics under low-inertia and weak-grid scenarios. The main aim is to highlight the risk of PLL interactions with the converter controllers under nonideal operating conditions. The nonlinear pH models of SRF-PLL and DSOGI-PLL are used to derive analytical stability criteria, which help monitor the effect of PLL interactions on synchronization stability. The stability criteria are substantiated through MATLAB/Simulink simulations on a 400-V Converter-Grid test system. It is shown that the stability criteria derived based on time-scale separation is inexact. In comparison, the proposed criteria, accounting for converter dynamics, offer better stability predictions and match closely with the simulation results.",

      "abstract": "This work proposes a new force-impedance controller design method for robot manipulators in the port-Hamiltonian (PH) framework. Compared with former work in the Euler–Lagrange (EL) framework, fewer control parameters and constraints are needed to achieve asymptotic stability. Besides, a clear physical interpretation can be given due to the PH formalism. First, a canonical transformation is adopted to recast the joint space model into a workspace model. We then achieve impedance control by shaping the inertial and stiffness matrices. Additionally, a change of variable strategy allows an integral force action, such that the force error is included in the system’s passive output. Furthermore, a damping injection is applied to obtain a smoother noncontact-to-contact transition. Finally, we conduct simulations and experiments to compare the advantages of our new force-impedance control law with respect to the EL approaches.",

      "abstract": "Continuum robots with variable compliance have gained significant attention due to their adaptability in unstructured environments. Among various stiffness modulation techniques, layer jamming (LJ) provides a simple yet effective approach for achieving tunable stiffness. However, most existing LJ-based continuum robot models rely on static or quasi-static approximations, lacking a rigorous control-oriented dynamical formulation. Consequently, they are unsuitable for real-time control tasks requiring simultaneous regulation of configuration and stiffness and fail to capture the full dynamic behavior of LJ-based continuum robots. To address this gap, this article proposes a port-Hamiltonian formulation for LJ-based continuum robots, formally characterizing the two key phenomena—shape locking and tunable stiffness—within a unified energy-based framework. Based on this model, we develop a passivity-based control (PBC) approach that enables decoupled regulation of stiffness and configuration with provable stability guarantees. We validate the proposed framework through comprehensive experiments on the OctRobot-I continuum robotic platform. The results demonstrate consistency between theoretical predictions and empirical data, highlighting the feasibility of our approach for real-world implementation.",

      "abstract": "Passivity-based control (PBC) for port-Hamiltonian systems provides an intuitive way of achieving stabilization by rendering a system passive with respect to a desired storage function. However, in most instances the control law is obtained without any performance considerations and it has to be calculated by solving a complex partial differential equation (PDE). In order to address these issues we introduce a reinforcement learning (RL) approach into the energy-balancing passivity-based control (EB-PBC) method, which is a form of PBC in which the closed-loop energy is equal to the difference between the stored and supplied energies. We propose a technique to parameterize EB-PBC that preserves the systems's PDE matching conditions, does not require the specification of a global desired Hamiltonian, includes performance criteria, and is robust. The parameters of the control law are found by using actor-critic (AC) RL, enabling the search for near-optimal control policies satisfying a desired closed-loop energy landscape. The advantage is that the solutions learned can be interpreted in terms of energy shaping and damping injection, which makes it possible to numerically assess stability using passivity theory. From the RL perspective, our proposal allows for the class of port-Hamiltonian systems to be incorporated in the AC framework, speeding up the learning thanks to the resulting parameterization of the policy. The method has been successfully applied to the pendulum swing-up problem in simulations and real-life experiments.",

      "abstract": "This article studies the 3-D dynamic rendezvous control problem for coordinated heterogeneous marine vehicles, including an uncrewed underwater vehicle (UUV) and an autonomous surface vehicle (ASV). An observer-based safety-preserving rendezvous control approach is proposed to robustly stabilize the rendezvous errors under the port-Hamiltonian (PH) framework. First, an interconnection and damping assignment passivity-based control (IDA-PBC) method is adopted to provide a basic stabilizing control framework. In this problem, both vehicles are faced with hydrodynamic model uncertainties and unknown external disturbances. Then, to preserve the rendezvous safety under uncertain dynamics, the prescribed performance control (PPC) transformation is implemented for the ascending motion to get the equivalent approaching-constrained PH system. The intuitive design procedure provided by the IDA-PBC method, along with the collision-free rendezvous safety guaranteed by the auxiliary PPC technique, reduces the controller design complexity while providing a smooth rendezvous trajectory. Besides, a structure-keeping uncertainty observer algorithm is designed and incorporated to simultaneously handle model uncertainties and environmental disturbances without destroying the interconnection structure. Under the proposed approach, the UUV-ASV rendezvous errors can be effectively stabilized with rigorous closed-loop stability analysis. Finally, both simulations and comparative experiments are conducted to demonstrate the effectiveness and advantages of the proposed approach.",

      "abstract": "The design of a passivity-based non-linear controller for a shunt active filter to be used for the compensation of the harmonic components consumed by non linear loads is presented in this paper. The main objective of this control strategy is to inject the necessary compensation current into the system so that the grid current is sinusoidal and balanced, regardless of whether the grid voltage is unbalanced and/or distorted. The reference values for the compensation currents are obtained from applying the Instantaneous Active-Reactive Power Theory. The system is represented by its port-controlled Hamiltonian model and the controller designed on the basis of interconnection and damping assignment using a method based on Lyapunov techniques. The behavior of the proposed control strategy is validated through simulation using a realistic model.",

      "abstract": "In this paper an interconnection and damping assignment passivity-based control (IDA-PBC) applied to the hydro-turbine governing systems (HTGS) is proposed to regulate the relative deviation of turbine speed in single machine infinite bus system. The passivity-based control (PBC) theory is selected because in the open-loop the HTGS has a port-Hamiltonian (pH) structure. The PBC theory takes advantage of the pH structure of the open-loop dynamical system to design a general control law, which preserves the passive structure in closedloop via interconnection and damping reassignment. Additionally, the PBC theory guarantees globally asymptotically stability in the sense of Lyapunov for the close-loop dynamical system. Time-domain simulations demonstrate the robustness and proper performance of the proposed methodology applied to the HTGS under different operative conditions.",

      "abstract": "This paper presents an integration of three-phase supercapacitor energy storage (SCES) in power grids via passivity- based control (PBC) theory under different reference frames. The SCES systems have the possibility to interchange active and reactive power between the supercapacitor and converter to the electrical power network. The active power is directly related to the energy stored on the supercapacitor, while the reactive power is redistributed by the forced commutated switches present in the voltage source converter (VSC) used to integrate the SCES system to the power grid. PBC theory allows designing Lyapunov stable controllers for autonomous and non-autonomous dynamical sys- tems via port-Hamiltonian (pH) representations. The averaging modeling theory employs to develop the controllers under abc, $\\alpha\\beta$ and $dq$ reference frames. Simulation results show the possibility of using the SCES devices to compensate active and reactive power in power grids dynamically in all operating quadrants. All simulations are conducted via MATLAB/SIMULINK software.",

      "abstract": "In this paper, a unified damping assignment passivity based control scheme (UDA-PBC) is proposed for PV-plants (PV-P) in the form of power conversion unit (PCU) connected to distribution power grids (DPGs). The PCU includes a super-capacitor unit (SCU), bidirectional buck/boost converter interfacing SCU to DC-link capacitor, and grid-side voltage-source converter (VSC) operating in cooperation with SCU. According to the maximum power point tracking (MPPT) algorithm, the boost converter extracts maximum active power from PV-P and feeds the power to the PCU. Then, the PCU using the unified operation of SCU and VSC based on the proposed control scheme damps possible DC-side and AC-side power oscillations and delivers the power smoothly to the DPG. To this end, the model of output filter associated to VSC in synchronous reference frame (SRF), DC-link capacitor, SCU are modeled as a 5-order nonlinear state space equation and represented in the port controlled Hamiltonian (PCH) form. Then, the unified nonlinear control of PCU is designed with the utilization of DA-PBC idea applied to the developed model. In addition to mathematical stability proofs, the effectiveness of the proposed strategy is verified based on a set of time-domain simulations and comparisons with conventional methods.",

      "abstract": "In the more electric aircraft context, dc distribution systems have a time-varying structure due to the flexible distributed loads and complex operation conditions. This feature poses challenges for system stability and increases the difficulty of the stability analysis. Besides, the risk of instability may be increased under constant power load condition due to the negative incremental impedance characteristic. To this end, this article proposes an improved interconnection and damping assignment passivity-based control scheme. Particularly, an adaptive interconnection matrix is developed to establish the internal links in port-controlled Hamiltonian models and to generate the unique control law. The damping assignment technique is addressed to tune the dynamic characteristic. In order to meet the load requirements of different voltage levels, the design procedures were given for determining the control law in both boost converter and buck converter cases. The simulation and experimental results are performed to demonstrate the validity of the proposed control approach.",

      "abstract": "It is well known that the interaction between cascaded individually designed power conversion systems can cause instability. To overcome this issue, a Hamiltonian energy control scheme is proposed, which is based on passivity control theory and port-controlled Hamiltonian framework. A complementary PI adjustment term is also included in the control algorithm to eliminate the steady-state output voltage error caused by the parameter uncertainty. The proposed control approach is applied to three different cascade structures. First, the cascade structure between dc/dc converters is considered, and the detailed controller design is given. Second, the cascade connection of a single converter and its LC filter is studied. By placing the LC filter into the Hamiltonian model of the controlled converter system, the dynamic and potential instability caused by the filter can be adjusted. Finally, the cascade structure between subsystems including filters and converters, which are common in microgrids, is studied. By using the Hamiltonian function (storage function) as the Lyapunov function candidate, the large-signal stability of each controlled converter system is proved. When the cascade structure contains multiple controlled converter systems, the stability of the entire cascaded system is guaranteed by the superposition of multiple Lyapunov functions. A 3.5 kW 220−270−350 V test bench is built in the laboratory to demonstrate the application of the proposed control approach to these three cascade structures.",

      "abstract": "Multiple cascaded filters can lead to instability in DC microgrids. To address this issue, this paper proposes a stabilization strategy for a DC microgrid with multiple cascaded filter subsystems. Stability is achieved by considering the cascaded input and output filters at the subsystem level and establishing a modified Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) strategy based on port-controlled Hamiltonian modelling. First, the general design procedure of the proposed control strategy and its large-signal stability proof are presented, and the stability of the entire microgrid is proved. Second, an example design of the controller considering the cascaded input and output filters source subsystem is given. Finally, the modified IDA-PBC strategy is applied to the basic unit of the DC microgrid, which includes the source subsystem of the cascaded input and output filters and the load subsystem of the cascaded input filter. The modified strategy is further applied to a complete DC microgrid containing multiple subsystems. The experimental results and hardware-in-the-loop results indicate the effectiveness of the proposed strategy.",

      "abstract": "Power electronics-based medium-voltage direct current (MVdc) microgrids consist of several interconnected feedback-controlled switching converters. Such systems experience bus voltage stability challenges owing to the negative incremental resistance of constant power loads and converter control loop interactions. To tackle the stability challenges, this paper presents the application of the interconnection and damping assignment passivity-based control (IDA-PBC) approach to the port-controlled Hamiltonian model of dual active bridge (DAB) source-side converters in an MVdc microgrid. For the DABs, a fundamental average model approach considering phase shift modulation is provided and used for deriving the corresponding IDA-PBC control law. We analyze the effectiveness of the controller on large signal scenarios considering disturbances such as load step up, and DAB disconnection. Hardware-in-the-Loop experiments using Opal-RT and Labview field programmable gate arrays (FPGAs), as well as, low power prototype tests are carried out to demonstrate the validity and feasibility of the proposed approach.",

      "abstract": "This article presents a nonlinear passivity-based control for a grid-connected cascaded H-bridge (CHB) photovoltaic (PV) system. The proposed control system is based on a port-controlled Hamiltonian model extracted from the synchronous reference frame system. Grid current dynamics is included in this model. Compared to existing solutions, the proposed control method has a robust performance and enhances the stability of the CHB-based PV system in the case of disturbances such as unequal irradiance over distinct PV arrays or a sudden sag or swell in the grid voltage. This controller also provides the independent control of each dc-link voltage. Therefore, the individual maximum power point tracking algorithms can be realized in each PV array, and the harvested energy can be maximized. Finally, simulation results and experimental investigations are conducted to verify the effectiveness of the proposed strategy.",

      "abstract": "With the increasing number of distributed generations connected to the grid, the inertia of power grid turns out to be decreased. To address this problem, the virtual synchronous generator (VSG) is proposed, which mimics the mechanical characteristics of the traditional synchronous generators (SGs). However, the introduction of virtual inertia will induce the transient angle instability, which threatens the security and stability of power system when the grid voltage sag occurs. Few methods can effectively tackle this problem, particularly, when the grid voltage sag is severe. In this article, the mechanism of transient angle instability is analyzed, and an enhanced transient angle stability (TAS) scheme is proposed. First, the VSG system is designed as a port-controlled Hamiltonian (PCH) system. Based on the energy shaping, the control law of the PCH system, i.e., the reference active power of VSG is constructed to be model based. Second, benefitting from this model, the TAS can be enhanced by modifying the reference active power via the state variable feedback. Thus, an enhanced TAS scheme that employs the power angle variation is proposed. Moreover, the proposed scheme is proved to be effective in terms of the equal area criterion (EAC) even if the severe grid voltage sag occurs. Finally, the simulations and experiments are carried out to validate the effectiveness of the proposed scheme.",

      "abstract": "Passivity based control (PBC) is an appealing solution to control power converters while ensuring the stability of more and more complex and modular electrical systems. However, the original interconnection and damping assignment-PBC (IDA-PBC) controller design method generates singularities in the control-variables leading to their saturation and spikes of current. This article highlights this nondesired phenomenon by applying the original IDA-PBC to the control of a boost converter. A novel controller design is then proposed to remove the singularities of the control-variables while preserving the proof of passivity of the whole controlled system. The proposed method introduces a new damping assignment approach to tune the performances of the system. This design can be applied to a specific subclass of port controlled Hamiltonian (PCH) systems which includes the average models of different converters. To highlight the generalization of the proposed method, it is applied to a 5th-order 2 kW 2-input modular three-level boost converter (MTL-BC), and validated experimentally. The advantage of the controller is presented for a microgrid system (MGS) application compared to other conventional control strategies and how it improves the stability margin in the presence of a constant power load (CPL).",

      "abstract": "In this article, a novel passivity-based control strategy is proposed for the exponentially stable tracking controller design of static synchronous compensator (STATCOM) system, which is a single input and single output. The STATCOM is not an input-affine system but a special port-controlled Hamiltonian system form. Hence, it is regularized by using a dynamic extension algorithm so that the proposed tracking control strategy is designed in an input–output linearization framework with a bounded solution to the driven zero dynamics equation. The proposed control strategy is proposed with consideration of the performance and stability of the input–output linearized dynamics. Simulation results show that the proposed control strategy improves the transient performance of the system compared to the previous results even in the lightly damped operating range.",

      "abstract": "Electricity industry marketization and combined heat and power (CHP) systems are actively considered efficacious approaches for balancing supply and demand in future energy systems with high penetration of renewable sources. Relevant research to date has paid little attention to the interaction of economic behaviors with the dynamics of the CHP system, focusing only on optimal bidding at the economic level or stability at the physical level. By leveraging the primal-dual method and the insights from reverse engineering, we propose a unified economic-physical model to investigate how market dynamics interact with its underlying physical CHP systems. The market clearing optimization is redesigned as a controller that restores the nominal frequency while maximizing social welfare. This work steps further toward developing a novel control scheme for frequency regulation in market-oriented power systems with CHP units and renewable sources. As the proposed model can be formulated in port-Hamiltonian form, the stability of the closed-loop system can be assessed using Lyapunov's direct method. The capability and effectiveness of the proposed model are demonstrated through simulations.",

      "abstract": "This article proposes an adaptive control for the power distribution of fuel cell (FC) hybrid electric vehicles. port-Hamiltonian framework is utilized to describe the fuel cell hybrid system dynamics. Then, the controller is designed in the interconnection and damping assignment passivity-based control approach to distribute the power flow between the fuel cell and the battery pack, and the stability of designed controller has been proved. Moreover, an adaptation law is utilized to improve the fuel economy and durability of energy sources, and the battery state of charge is online estimated by a quasi-sliding-mode observer. Finally, simulation and experiments are conducted to verify the performance of proposed controller compared with an equivalent consumption minimization strategy.",

      "abstract": "Industrial circuit systems are subject to significant information uncertainties, such as noise, incomplete state measurements, unknown loads, and lumped disturbances, which can jeopardize stability and safety. This article addresses these challenges in stochastic port-Hamiltonian systems (SPHSs) through novel control strategies. A reduced-order observer, formulated via linear matrix inequalities, is developed to observe system states when complete measurements are unavailable. We prove that the observation error converges to zero both in almost sure and mean square senses. For SPHS with lumped disturbances, a disturbance observer enables feedforward compensation by observing unknown disturbances. In addition, tunable estimators are proposed to identify constant but unknown loads, with performance optimized through function selection. Furthermore, based on stochastic versions of LaSalle’s invariance principle and Barbalat’s lemma, we prove that a SPHS which is passive under constant control is also stabilizable via proportional–integral control. The efficacy of the proposed methods is demonstrated through circuit simulation examples, confirming their applicability in mitigating information uncertainties in industrial environments.",

      "abstract": "In this paper, a new passivity-based control approach is designed to improve the robustness and stability of autonomous vehicles in performing path-tracking tasks. A port-Hamiltonian model is a special geometric structure and provides a systematic and insightful framework to describe many physical systems from an energy perspective. The passivity-based control establishes a new and simple structure to achieve the path-tracking task by the port-Hamiltonian structure. Firstly, the path-tracking error system is transformed into a port-Hamiltonian system with the perturbation. The energy-shaping method is utilized to ensure the asymptotic stability, and the stability proof of the closed-loop, path-tracking error system is given. The proposed real-time, passivity-based controller is directly dependent on the passive outputs, which is robust to parameter uncertainties caused by load changes. Moreover, the control performance of steering control will be degraded when the steering angle is saturated. The yaw-moment control is introduced to enhance the driving safety. In the wheel torque distribution, an optimization-based control allocation is designed to minimize the sum of tire loads and to make them more evenly distributed to each tire. Finally, simulations are implemented in MATLAB/Simulink and CarSim co-simulation to demonstrate the effectiveness of the designed strategy under different driving conditions.",

      "abstract": "In this paper, we present a novel underactuated gantry crane (GC) systems where an extra degree-of-freedom actuation is introduced to control the trolley position and its sway angle during motion. The proposed gantry crane systems resembles a prismatic-revolute-prismatic (PRP) robotic configuration where the revolute joint corresponds to the sway angle which is not actuated. Firstly, an energy-based modeling of the PRP-GC systems is presented where both Euler-Lagrange and port-controlled Hamiltonian formalisms are used. Secondly, we present the design of a Neural Interconnection and Damping Assignment Passivity-Based Controller (N-IDA-PBC) that allows for an automated learning of an IDA-PBC controller, where the solutions to the corresponding IDA-PBC matching PDE are not trivial for underactuated systems. Finally, the efficacy of the proposed N-IDA-PBC is evaluated through Monte Carlo simulations, where the neural networks training of N-IDA-PBC uses $3,000$ randomly generated data points and $20,000$ samples of Monte-Carlo simulation are performed, taking into account uncertainties in the systems’ parameters, including initial states, physical damping, and payload masses. The Monte-Carlo simulations show that the trained N-IDA-PBC is able to regulate the trolley position and sway angle to the set-point position and it is robust against parameter uncertainties.",

Hence, adaptive path-tracking control with a passivity-based observer is designed by the port-Hamiltonian model for autonomous vehicles in this article. Firstly, a passivity-based observer of lateral velocity is established by designing a gain matrix to assign the interconnection and damping parts, which makes an observation error system transform into a desired port-Hamiltonian system and renders the observer passive. At the same time, it's convergence and stability analysis is given. Then, a port-Hamiltonian model with perturbations and actuator saturations is constructed to describe lateral vehicle dynamics in terms of tracking errors for path-tracking, and an L2-gain disturbance attenuation strategy is developed to overcome the adverse influence caused of external disturbances. Furthermore, the robust stability of the controller is proved in the presence of observation errors and external disturbances. Finally, simulations and experiments are performed to demonstrate the effectiveness of the proposed control strategy.",

The control objectives are to inject all the generated power into the grid and control the reactive power exchanged with the power system. The system is represented by its port-controlled Hamiltonian model and the controller is designed by interconnection and damping assignment. The design of the controller allows a direct control of the DC link dynamics and avoids the use of derivatives in the implementation of the control equations. The performance of the proposed control strategy is validated through simulations.",

These field formulations are based on the Darwin–Ampére equation and yield different approximations of the full set of Maxwell’s equations depending on the choice of additional equations. Various discrete EMQS formulations are analyzed using the port-Hamiltonian system framework. It is shown that several symmetric EMQS formulations, e.g., combinations of the Darwin–Ampére equation and the Maxwell continuity equation, yield port-Hamiltonian differential-algebraic equation (pH-DAE) systems, which implies their numerical stability, energy conservation related to a specific EMQS variant of the Hamiltonian and dissipativity results.",

      "abstract": "Vibration suppression and precise tracking are the two main challenges in the control of elastic joint robots. In this study, an elastic joint robot with precise position sensors on both the motor and link sides is developed to tackle these challenges. With a two-mass model for elastic joint and a LuGre friction model for joint friction, the elastic joint robot system is modeled and analyzed as an underactuated port-controlled Hamiltonian system with dissipation (PCHD). The proposed elastic joint controller is integrated with friction compensation using the interconnection and damping assignment passivity-based control method, leading to a PCHD closed loop system that can be effectively tuned to suppress vibration associated with elastic joints. In addition, integral control is employed to achieve high tracking precision. Experiments have been conducted and the results have demonstrated high performance of the proposed control method.",

      "abstract": "This article deals with the control-oriented energy-based modeling of ionic polymer–metal composite (IPMC) patches using multiscale infinite dimensional port-Hamiltonian formulations and Lagrange multipliers. Inspired by the work of Nishida et al. in 2012, but considering different assumptions, this article focuses on the constraints arising from the coupling between the polymer gel and the compliant mechanical structure of the actuator, under the quasi-static mechanical assumption for the gel, leading to a constrained port-Hamiltonian system. The geometric structure of the overall system and the associated energy balance are derived. The proposed energy-based model of the IPMC actuator allows deriving controllers via energy-based control design methods with a clear physical interpretation. The proposed actuator model is further discretized in space using a structure preserving finite difference method. The Lagrange multipliers are eliminated using coordinate projections. Simulations are compared with experimental results. With proper discretization numbers, our model is consistent with the physical system. Finally, Lagrange multipliers are exploited to connect the actuator to a 2-D flexible structure stemming from the modeling of a flexible endoscope.",

      "abstract": "Soft continuum manipulators are characterized by low stiffness that allows safe operation in unstructured environments but introduces underactuation. In addition, soft materials such as silicone rubber, which are commonly used for soft manipulators, are characterized by nonlinear stiffness, while pneumatic actuation can result in nonlinear damping. Consequently, achieving accurate control of these systems in the presence of disturbances is a challenging task. This article investigates the model-based adaptive control for soft continuum manipulators that have nonlinear uniform stiffness and nonlinear damping, that bend under the effect of internal pressure, and that are subject to time-varying disturbances. A rigid-link model with virtual elastic joints is employed for control purposes within the port-Hamiltonian framework. The effects of disturbances and model uncertainties are estimated adaptively. A nonlinear controller that regulates the tip orientation of the manipulator and that compensates the effects of disturbances and of model uncertainties is then constructed by using an energy shaping passivity-based approach. Stability conditions are discussed highlighting the beneficial role of nonlinear damping. The effectiveness of the controller is assessed with simulations and with experiments on a soft continuum manipulator prototype.",

      "abstract": "In this article, we present a novel energy-based control architecture on Euler–Bernoulli beams equipped with a variable stiffness mechanism. To proof the methodological validity of the approach, two control laws are developed using the power balance of the system, explicitly encoded in its infinite-dimensional port-Hamiltonian formulation. The laws are designed to stabilize the beam and to induce limit cycles on it, respectively, increasing damping by removing energy from the system and countering damping by injecting energy into the system. The variable stiffness mechanism is realized through a distributed axial load, applied by means of a wire on a winch, and is able to achieve effective stiffness variation due to softening. An experimental setup is designed to validate the theory. 3-D-printed, embedded, piezoresistive strain gauges are used as sensing units for closed-loop control. We show how the developed approach conveniently deals with such sensors, overcoming potential problems arising from their nonideal response. Experimental results show the validity and the robustness of the proposed control laws. High speed videos are used to validate the measurements.",

      "abstract": "This article presents an energy-based modeling and control design method for a piezotube actuated optical fiber. A nonlinear infinite dimensional port Hamiltonian (pH) formulation of the 3-D flexible optical fiber is derived from the Cosserat rod dynamical equations. Then, the proposed infinite dimensional model is discretized using a pH structure and passivity preserving discretization method for the simulation and control design. This model is then validated against experimental data obtained using a built-in experimental setup equipped with a MEMS Analyzer. A complete pH formulation of the piezotube actuated optical fiber is proposed, combining the Cosserat rod model and actuator dynamics. This model is used for the end-point path control design using an interconnection and damping assignment passivity based control (IDA-PBC) method. Both the proposed pH model of the overall system and the controller are validated in simulation and against experimental results.",

      "abstract": "Current studies struggle to achieve multiobjective optimization for overactuated electric vehicles. This article proposes a cohesive hierarchical architecture that integrates coordinated control with velocity optimization, enabling tracking of desired planar motions while ensuring ride comfort and energy efficiency. First, a velocity optimization strategy based on the deep deterministic policy gradient is developed to achieve comfortable and energy-efficient driving. Desired vehicle states are generated by a reference model. The stability of the coordinated control is then formulated as a tracking problem for these desired vehicle states. To account for parameter uncertainties and external disturbances, a port-Hamiltonian model is employed to describe nonlinear planar motions incorporating four-wheel dynamics of overactuated electric vehicles. A robust passivity-based control method with guaranteed stability is developed using this model to track the desired vehicle states. Furthermore, to reduce sensor costs and improve measurement reliability, a real-time nonlinear observer is designed to accurately estimate lateral velocity. The stability of the overall system is analyzed considering estimation errors. Finally, simulation and experimental results demonstrate the effectiveness of the proposed method compared to existing approaches across various driving scenarios.",

      "abstract": "The port-Hamiltonian form (PHF) of nuclear reactor dynamics is first given with the corresponding Hamiltonian function determined by the shifted-ectropies of neutron kinetics and reactor thermal-hydraulics. Then, a passivity-based control (PBC) is proposed by adding extra damping injections to the PHF, and it is shown by theoretical analysis that satisfactory closed-loop stability can be guaranteed. The newly designed control law is applied to a nuclear heating reactor, and the simulation results not only verify the theoretical analysis but also show the satisfactory reactor power-level control performance.",

      "abstract": "Both interpersonal communication and media contact are important information sources and play a significant role in shaping public opinions of large populations. In this paper, we investigate how the opinion-forming process evolves over social networks under the media influence. In addition to being affected by the opinions of their connected peers, the media cooperate and/or compete mutually with each other. Networks with mixed cooperative and competitive interactions are said to be coopetitive. In this endeavor, a novel mathematical model of opinion dynamics is introduced, which captures the information diffusion process under consideration, makes use of the community-based network structure, and takes into account personalized biases among individuals in social networks. By employing port-Hamiltonian system theory to analyze the modeled opinion dynamics, we predict how public opinions evolve in the long run through social entities and find applications in political strategy science. A key technical observation is that as a result of the port-Hamiltonian formulation, the mathematical passivity property of individuals’ self-dynamics facilitates the convergence analysis of opinion evolution. We explain how to steer public opinions towards consensus, polarity, or neutrality, and investigate how an autocratic media coalition might emerge regardless of public views. We also assess the role of interpersonal communication and media exposure, which in itself is an essential topic in mathematical sociology.",

      "abstract": "In this paper, three results are presented concerning certain computational/control aspects, crucial for the proper behavior of haptic devices. The first one is a novel technique for a real-time simulation of virtual environments, which is able to preserve the energetic behavior of the simulated physical system and to avoid undesired effects related to unstable behaviors of the haptic device. The proposed real-time integration method is simpler, in terms of computational complexity, than similar solutions known in the literature, and provides an additional insight when “faulty conditions” are met. Second, a new method for the energy-consistent interconnection of discrete-time physical systems, implemented by algorithms running at different frequencies (i.e., multirate systems), is illustrated. Multirate systems are very common in haptics, since the frequency, at which the control law of the haptic interface is executed, is usually higher than the frequency of the simulation of the virtual environment. Finally, the third result presented in this paper concerns the problem of energy generation due to the time discretization in the acquisition of the haptic interface position. Similarly, to the previous case, a technique for an energy-consistent analog/digital conversion is proposed. All these methodologies have been validated, both by simulations and experiments.",

      "abstract": "The underlying voltage/current tracking control is a key issue for a hybrid energy storage system (HESS) in electric vehicles. This article presents an innovative passivity-based L2-gain adaptive robust control (L2-ARC) method for a fully active battery/super-capacitor HESS. First, by exploiting and analyzing the internal structural properties, the port-controlled Hamiltonian model with dissipation for HESS is derived and then, the interconnection and damping assignment-passive based controller (IDA-PBC) is designed to realize the underlying control, where the rule-based energy management strategy is adopted to generate the current references. To overcome the adverse influence of external disturbances and parameter perturbations under complex driving conditions, by combining the L2 gain disturbance attenuation technique with the IDA-PBC method, the L2-ARC method is developed to guarantee fast response, high performance, and robust stability. Moreover, an adaptive mechanism is adopted to estimate the electrical parameters. The performance of L2-ARC is thoroughly investigated and compared through comprehensive case studies with traditional PID, IDA-PBC, and sliding mode controllers. Finally, a control prototype is implemented to validate L2-ARC.",

      "abstract": "In this article, a passivity-based virtual oscillator control strategy with enhanced synchronization stability for grid-forming inverters (GFMs) is proposed. By adopting the port-controlled Hamiltonian system theory for orbital stabilization problems, an energy pumping-and-damping block is proposed to render GFMs globally asymptotically stable with respect to the prespecified solutions of the power-flow equations from any initial condition. This allows for stable integrations of GFMs to any other globally asymptotically stable systems without their explicit knowledge, e.g., helping maintain synchronism with the bulk power system in a wide range of short-circuit-ratio conditions or under large disturbances and keeping synchronism among multiple GFMs in power systems. Both simulations and experiments are presented to demonstrate the proposed control approach.",

      "abstract": "This article presents a modified dispatchable virtual oscillator control approach for achieving the passivity of grid-forming inverters (GFMs), without assuming constant voltage and constant frequency. The proposed control framework utilizes the port-Hamiltonian (PH)–based structure that mimics the behaviors of coupled harmonic oscillators, along with an energy “pumping-or-damping” block and the control by interconnection technique, to render the inverter passive. Once passivity is achieved, the transient stability of the system will be guaranteed. The proposed control framework is composed of three loops: an outer power dispatching loop that generates the voltage and frequency references, a virtual oscillator loop that emulates the spontaneous synchronization of oscillators, and an inductor current loop that maintains lossless interconnection in PH systems. The study shows that the proposed control approach ensures the passivity of GFMs, facilitating the transient stability design of multi-inverter systems, as interconnections of passive systems remain passive and stable.",

      "abstract": "This article investigates the high-speed and high-precision control problems of permanent magnet synchronous motor (PMSM) servo system under actuator faults, input constraints, and unknown load conditions. From the perspective of signal processing and energy transformation, consider the PMSM servo system as a unified entity of multiport signal processing and energy transformation. Then, a signal processing-based fixed time integral-type sliding mode control algorithm is designed to achieve fast dynamic trajectory regulation in dynamic process. By using the energy transformation-based fixed time error port-controlled Hamiltonian control method, the precise trajectory tracking and energy loss optimization control can be realized in steady-state process. Furthermore, a cooperative optimization control strategy based on convex combination mechanism is proposed, which fully utilizing the advantages of signal processing-based control and energy transformation-based control. A fixed time input constraint compensation mechanism is introduced to address the problem of input constraints. In addition, a fixed time-extended state observer is designed to handle actuator faults and unknown load problems, which can quickly observe faults and unknown load states, effectively improving fault tolerance and multisource uncertainties suppression performances of system. Finally, utilizing the Lyapunov criterion, the stability of the entire closed-loop system is discussed, and a large number of experimental results verified the effectiveness of the proposed strategy.",

      "abstract": "Recent years, the virtual synchronous generator (VSG) is widely used in practice, owing to its ability to emulate the behavior of traditional synchronous generators. However, a challenge issue emerges during load changes, namely, the active power oscillation tends to cause overload and frequency stability deterioration, especially in the parallel VSGs system. Although some studies have tried to address this issue, the effectiveness of conventional methods based on small signal model (model linearization) are influenced by the change of equilibrium point. And the linear method of parallel VSGs system is lack of a stable design framework. As the number of VSGs increases, the order of model will increase rapidly, then the stability of parallel system is difficult to be proven by the root locus or other linear stability criteria. Therefore, in this article, the port-controlled Hamiltonian model is first built, which provides a stable framework for control law designing. Then, this model is employed to investigate the impact of coupling effect between parallel VSGs, which induces the oscillation. Furthermore, to mitigate the active power oscillation and enhance the frequency stability, the coupling effect is regarded as the disturbance, and a control law is proposed to constrain the impact of disturbance based on the L2-disturbance attenuation. Finally, effectiveness of the proposed strategy is validated by simulations and experiments.",

      "abstract": "We perform a finite-horizon controllability and reachability analysis of tokamak electromagnetic field profiles using a 0-D resistive-diffusion model in the port-Hamiltonian (PH) framework. With a quadratic Hamiltonian, the PH dynamics reduce to a linear realization, and allowing plasma parameters to vary in time produces a linear time-varying (LTV) system suitable for finite-horizon analysis. Focusing on a flat-top window after electron cyclotron current drive (ECCD) reaches its setpoint, we treat the boundary loop voltage and localized ECCD as inputs and evaluate reachability and controllability Gramians in energy-normalized coordinates. The reachability Gramian bounds the minimum input energy needed to achieve target profile changes from rest, and the controllability Gramian bounds the effort to drive perturbations to zero. Their eigenstructures expose well- and poorly actuated directions. We summarize actuation authority with two metrics—the minimum eigenvalue (worst case effort) and the log-determinant (log-volume of the reachable/controllable ellipsoid)—which provide energy-based bounds for realistic objectives. Applied to the flat-top window, our analysis shows that actuator placement and early-window actuation dominate profile-shaping authority, yielding simple rules that turn tuning into quantitative feasibility checks and reduce experimental risk.",

      "abstract": "The existed control methods of the multi-area load frequency control (LFC) system fail to decouple the total tie-line power flow. This defect can be addressed as a problem on how to effectively utilize the total tie-line power flow. To improve that defect, the energy and structure of multi-area LFC system have been carefully studied, such that, the energy goes through the systemic cascade parts and the systemic structure matrix is partially skew symmetry. Namely, the energy and structural properties of the multi-area LFC system are similar to the properties of Port-Hamiltonian (PH) system and cascade system. Inspired by the above properties, a new method based on the PH system and cascade system that is proposed to design some PID control laws for the multi-area LFC system successfully works out the aforementioned problem. Compared with the existed PID methods for the multi-area LFC system, the proposed method has two advantages, which are the decoupling of total tie-line power flow and the robust disturbance rejection. At last, simulations results demonstrate the validity and advantages of the proposed method.",

      "abstract": "The traction blockade in depots of multiple electric multiple units (EMUs) is generally considered to be caused by the voltage low frequency oscillation (LFO) of the high-speed railway traction network. As a possible solution, a strategy using single-phase EMUs rectifiers with passivity-based control (PBC) is proposed in this paper. First, the mathematical model of the four-quadrant pulse width modulation rectifier is constructed based on the port controlled Hamiltonian with dissipation. Next, with the insertion of damping, the new energy function can be minimized at the equilibrium point of the system, which enables the derivation of the rectifier control law based on the interconnection and damping assignments PBC. Comparison of simulation results with those of the traditional proportional integral (PI) scheme, autodisturbance rejection control and multivariable control verifies that the proposed PBC controller has better dynamic and static performance. Among all strategies considered, the resulting line current has the least total harmonic distortion, and the dc-link voltage of single-phase EMUs rectifier has the least oscillation and the shortest adjustment time, when using the PBC. Meanwhile, the simulations of multi-EMUs accessed a traction network show that the proposed method significantly suppresses the voltage LFO of the traction network. Finally, the LFO signal modal analysis is performed using the fast Fourier transform and the estimating signal parameters via the rotational invariance techniques. It indicates that PBC can suppress the symmetrical frequency components and effectively reduce the third, fifth, and other harmonic components compared with the PI control in EMUs.",

      "abstract": "A new energy-dissipating hybrid control framework is proposed in this paper. The proposed framework incorporates a plant with continuous dynamics connected in parallel with a hybrid controller that combines logical switches with continuous dynamics. The overall closed-loop system can be described as a hybrid impulsive dynamical system in which the redundant energy preserved in the plant can be damped quickly and continuously due to the enhanced dissipativity of the closed-loop system. The proposed framework is applied to design decentralized nonlinear excitation controllers for synchronous generators in a multimachine system to improve its transient stability, in which the synchronous generators are modeled as port-controlled Hamiltonian systems. Simulation studies on the IEEE 10-generator, 39-bus New England power system are carried out to verify the effectiveness of the proposed energy-dissipating hybrid excitation control to improve the transient stability and dissipativity of the interconnected power system under various fault conditions.",

      "abstract": "This paper proposes an interconnection and damping assignment passivity-based control (IDA-PBC) for multimachine power systems including hydro-turbine governing systems (HTGS) with surge tank. The main objective is to stabilize the rotor speed and regulate the terminal voltage of each synchronous machine in a power system. The proposed control is decentralized, thus avoiding challenges of communication between generators. Passivity theory is used since the open-loop of the HTGS presents a port-Hamiltonian structure. IDA-PBC allows a control law that maintains the passive structure in closed-loop, guaranteeing its asymptotic stability using Lyapunov's theory. The dynamics of each HTGS are described by an eleventh-order model, which can be reduced to a tenth-order. The proposed control is tested in a 12-bus test system and compared to a standard control, which considers a voltage regulator and exciter based on the IEEE type ST1A excitation system model and power system stabilizer IEEE-PSS1A. The governing system based on a PID control with static and transient droop is also employed. Additionally, the proposed controller is compared to a sliding mode controller. Time-domain simulations demonstrate the robustness and appropriate performance of the proposed decentralized control under different large disturbances.",

There will be no analysis of the time delay, but its presence justifies the use of scattering variables to preserve passivity. The contributions of the paper are twofold: first, a geometrical, multidimensional, power-consistent exposition of telemanipulation of intrinsically passive controlled physical systems, with a clarification on impedance matching, and second, a system theoretic condition for the adaptation of a general port-controlled Hamiltonian system with dissipation (port-Hamiltonian system) to a transmission line.",

      "abstract": "In this paper, a simple way to model flexible robotic links is presented. This is different from classical approaches and from the Euler-Bernoulli or Timoshenko theory, in that the proposed model is able to describe large deflections in 3D space and does not rely on any finite-dimensional approximation (e.g., modal approximation). The model has been formulated within the port Hamiltonian formalism because intuitive considerations on the geometric behavior of the elastic link naturally define a Stokes-Dirac structure, the kernel of a port Hamiltonian system. Moreover, port Hamiltonian systems can be easily interconnected, thus allowing the description of complex systems as a composition of parts in an object-oriented way. By combining rigid bodies, springs, dampers, joints and, finally, flexible links, it is virtually possible to model and mathematically describe whatever complex mechanical structure formed by beams. In order to demonstrate the dynamical properties of the model and how complex mechanisms can be obtained by port interconnection, simulations of 1-DoF and 2-DoF serial manipulators and of a 2-DoF flexible closed kinematic chain are presented.",

      "abstract": "In this paper, a systematic procedure for the definition of the dynamical model in port-Hamiltonian form of mechanical systems is presented as the result of the power-conserving interconnection of a set of basic components (rigid bodies, flexible links, and kinematic pairs). Since rigid bodies and flexible links are described within the port-Hamiltonian formalism, their interconnection is possible once a proper relation between the power-conjugated port variables is deduced. These relations are the analogous of the Kirchhoff laws of circuit theory. From the analysis of a set of oriented graphs that describe the topology of the mechanism, an automatic procedure for deriving the dynamical model of a mechanical system is illustrated. The final model is a mixed port-Hamiltonian system, because of the presence of a finite-dimensional subsystem (modeling the rigid bodies) and an infinite-dimensional one (describing the flexible links). Besides facilitating the deduction of the dynamical equations, it is shown how the intrinsic modularity of this approach also simplifies the simulation phase.",

      "abstract": "This paper proposes a modeling method for generic compliant robotic manipulators. It is based on graph theory and the port-Hamiltonian formalism, which allows a modular approach to the interconnection of rigid bodies with compliant actuators by means of kinematic pairs. This modularity enables a simple and straight-forward adaption the model when a manipulator's actuator morphology is changed. An example of a spatial three degree-of-freedom manipulator shows that this modeling method is more suitable for modeling changes in actuator placement than the traditional Euler–Lagrange method.",

      "abstract": "This paper presents a new procedure to design a control law using the classical interconnection and damping assignment technique within the passivity-based port-Hamiltonian framework. The sought goal is to reduce the complexity of solving the so-called matching equations. The proposed approach is applied to two case studies of planar rolling nonprehensile manipulation, namely, the ball-and-beam and the eccentric disk-on-disk. The performance of the resulting controllers is illustrated through both simulations and experimental results, showing the applicability of the design in a real setup.",

      "abstract": "This work addresses the interaction control problem of a fully actuated aerial vehicle considered as a flying end-effector. We tackle the problem using geometrically consistent variable-stiffness impedance control for safe wrench regulation using the concept of energy tanks, where both the modeling and the control are carried out in the port Hamiltonian framework. We exploit previous well-known results in the literature of ground manipulators and extend them to be applied for novel and challenging aerial physical interaction with a focus on quasi-static applications. The energy-awareness of the presented control method guarantees the stability of the aerial robot in both free-flight and in-contact scenarios together with a level of safety in the case of contact-loss with the unknown environment. Furthermore, by utilizing bond graphs we demonstrate how the closed-loop passivity can be graphically conducted. The validity of our proposed approach is shown via several experiments. We also provide several insights on how the proposed framework could be extended to a generic dynamic aerial physical interaction.",

      "abstract": "Accurate models of robot dynamics are critical for safe and stable control and generalization to novel operational conditions. Hand-designed models, however, may be insufficiently accurate, even after careful parameter tuning. This motivates the use of machine learning techniques to approximate the robot dynamics over a training set of state-control trajectories. The dynamics of many robots are described in terms of their generalized coordinates on a matrix Lie group, e.g., on $\text{SE}(3)$ for ground, aerial, and underwater vehicles, and generalized velocity, and satisfy conservation of energy principles. This article proposes a port-Hamiltonian formulation over a Lie group of the structure of a neural ordinary differential equation (ODE) network to approximate the robot dynamics. In contrast to a black-box ODE network, our formulation embeds energy conservation principle and Lie group's constraints in the dynamics model and explicitly accounts for energy-dissipation effect such as friction and drag forces in the dynamics model. We develop energy shaping and damping injection control for the learned, potentially under-actuated Hamiltonian dynamics to enable a unified approach for stabilization and trajectory tracking with various robot platforms.",

      "abstract": "Achieving accurate closed-loop position control of soft robots remains an ongoing research problem, due to the challenges posed by underactuation, elastic nonlinearities, and material creep. Although soft driving technologies relying on tendons and smart material transducers (e.g., dielectric elastomers, shape memory alloys) offer more ease of controllability compared to pneumatics, the corresponding controller design problem becomes even more challenging because of additional nonlinear effects. Those include a configuration-dependent actuation matrix, that stems from the kinematics of the actuation, and control input saturation, which is especially critical for smart material actuators. In this article, we investigate for the first time the closed-loop position control of a soft-robotic system driven by dielectric elastomer actuators. The objective is to regulate the robot state to a constant setpoint, accounting for the effects of open-loop instability, underactuation, control input saturation, and constant external disturbances. To achieve this goal, we propose a model-based feedback scheme, which combines a stabilizing energy-shaping controller with a robustifying PI-like law. After presenting the general theory, a linear matrix inequalities algorithm is proposed to practically address the controller design in spite of strong model nonlinearities. Experimental validation conducted on a prototype of the soft-robotic system confirms the effectiveness of the proposed control approach.",

      "abstract": "The networked nature of multirobot systems presents challenges in the context of multiagent reinforcement learning. Centralized control policies do not scale with increasing numbers of robots, whereas independent control policies do not exploit the information provided by other robots, exhibiting poor performance in cooperative-competitive tasks. In this work, we propose a physics-informed reinforcement learning approach able to learn distributed multirobot control policies that are both scalable and make use of all the available information to each robot. Our approach has three key characteristics. First, it imposes a port-Hamiltonian structure on the policy representation, respecting energy conservation properties of physical robot systems and the networked nature of robot team interactions. Second, it uses self-attention to ensure a sparse policy representation able to handle time-varying information at each robot from the interaction graph. Third, we present a soft actor–critic reinforcement learning algorithm parameterized by our self-attention port-Hamiltonian control policy, which accounts for the correlation among robots during training while overcoming the need of value function factorization. Extensive simulations in different multirobot scenarios demonstrate the success of the proposed approach, surpassing previous multirobot reinforcement learning solutions in scalability, while achieving similar or superior performance (with averaged cumulative reward up to $\\times {\\text{2}}$ greater than the state-of-the-art with robot teams $\\times {\\text{6}}$ larger than the number of robots at training time). We also validate our approach on multiple real robots in the Georgia Tech Robotarium under imperfect communication, demonstrating zero-shot sim-to-real transfer and scalability across number of robots.",

      "abstract": "This article proposes a supplementary controller for inverter based distributed generations (DGs) to damp out the power and frequency oscillations that may occur following the change in the operation mode of Microgrids (MG). The proposed supplementary controller is implemented in synchronous reference frame (SRF) using the port-controlled Hamiltonian modeling strategy. The proposed supplementary controller can be readily integrated into the existing controllers that are commonly used as the main controllers in inverter-based Distributed Generators (DGs). The proposed supplementary controller is designed in such a way that improves the response of DGs during the system oscillations without affecting the steady state reference tracking performance of the DGs. The proposed supplementary controller is able to inject damping to both relative-degree-one (RD1) and higher-relative-degree (HRD) states of the inverters. The effectiveness of the proposed supplementary control for enabling seamless transitions between operation modes of MGs is demonstrated using a set of time domain simulations in a multi-source MG.",

      "abstract": "This paper investigates the consensus problem in a class of multi-agent systems with port-Hamiltonian dynamics, where agents update their states through information exchange with their neighbours to achieve consensus. However, the communication process poses a risk of leaking an agent's exact state to other agents or external eavesdroppers, resulting in a potential privacy breach. To address this issue, we propose a distributed consensus controller designed with privacy protection. With the proposed controller, the interaction among multiple agents only depends on their own estimation to the average output of the whole, thus avoiding explicit state sharing. Additionally, the multi-agent systems maintain the passive characteristic, making the Hamiltonian function a natural choice as the Lyapunov function candidate. Furthermore, we prove that the multi-agent systems converge exponentially to the equilibrium where the outputs of the multi-agent systems achieve consensus, and provide the corresponding convergence rate. Finally, a simulation example is presented to illustrate the effectiveness of the proposed controller.",

      "abstract": "The globally fixed-time stabilization and $H_{\\infty }$ control for the port-Hamiltonian differential algebraic equation (PH-DAE) is addressed by applying the structural properties of the port-Hamiltonian (PH) systems, and the interconnection and damping assignment passivity-based control (IDA-PBC) technique. For fixed-time control design of the differential algebraic equation systems, the main obstacle lies that the algebraic variables are hidden in the system and their dynamics are ambiguous. We propose an available and effective approach to overcome this obstacle. The system variables are decomposed into differential component and the algebraic component, and the explicit representation of the dynamics of algebraic component is obtained. Fist, we investigate the locally fixed-time stabilization control as well as globally attractive for PH-DAE. Second, we focus on solving the globally fixed-time stabilization and $H_{\\infty }$ control problems by jointly taking advantage of the locally fixed-time stabilization control for the origin and the globally fixed-time attractivity control for a predeterminate region. Finally, in order to address fixed-time stabilization control and $H_{\\infty }$ control for PH-DAE, new controllers are designed. Moreover, the convergence time of systems can be easily estimated after external disturbance vanishes. The efficiency of the theoretical results acquired in present article is verified via two examples with numerical simulation.",

To better deal with the uncertainties of each mode, an improved MDADT scheme along with corresponding constraint conditions is established, and the criterion on globally uniformly asymptotical stability is presented for SUPCH systems in unforced form under the new MDADT mechanism. Subsequently, based on mode-dependent state feedback (MDSF) strategies, the sufficient conditions are derived for stabilization of SUPCH systems. Furthermore, to solve <inline-formula> <tex-math notation=\"LaTeX\">$\\mathcal {H}_{\\infty }$ </tex-math></inline-formula> control problem for SUPCH systems with disturbances, a set of MDSF controllers are constructed, and the <inline-formula> <tex-math notation=\"LaTeX\">$\\mathcal {H}_{\\infty }$ </tex-math></inline-formula> control criterion is obtained by the improved MDADT scheme. Finally, as an application, some simulations on a switched nonlinear RLC circuit system with structural uncertainties are carried out by the proposed control strategies.",

      "abstract": "Interaction stability is an important concern in variable admittance control, and it is a prerequisite for achieving the desired compliant interaction with humans or uncertain environments. Different variable admittance controllers with essential stability analyses are required for multiple interaction scenarios in a complex task, where stability analysis is the major difficulty. In this article, we propose a unified stability-guaranteed variable admittance control architecture to decrease the control system complexity, in which we represent the admittance control model as a port-Hamiltonian (pH) system and design an energy tank with the optimization theory. The advantages of the proposed architecture are reflected in several aspects: 1) compatibility with common strategies; 2) perturbation resistance; and 3) passivity as a natural property. As the dissipated energy from the pH system is injected into the energy tank while the energy in the tank is used to support the interaction and perturbation resistance, the best passive approximation of the desired behaviors is generated, which can avoid the control signal failure (control signal failure denotes that the unexpected input $u=0$ occurs due to a lack of energy in the tank). Three different groups of experiments are conducted to verify the feasibility, perturbation resistance, and practicality of the proposed architecture.",

      "abstract": "This paper proposes a nonlinear supplementary controller for enhancing the transient response of distributed generations (DGs) in micro-grids. The proposed supplementary control system is based on an interconnection and damping assignment passivity-based controller and is designed according to the port-controlled Hamiltonian model of DGs. The controller is applied to the decentralized unified control scheme of DGs that enables seamless transitions between islanded and grid-connected modes. The proposed controller is generic and can be applied to DGs with different types of primary sources. The stability of the proposed supplementary controller is verified analytically, and the performance of the proposed controller is verified in a multi-resource micro-grid via time-domain simulations.",

      "abstract": "Rapid developments in hydrogen fuel cell (FC) energy and DC microgrid systems have extended the applications of multiphase parallel interleaved step-up converters for stabilizing DC bus voltages. DC microgrid applications include vehicle systems, shipboard power systems, and more electric aircraft, which generate power at low voltage levels. The cascade architecture of a power converter in a DC microgrid may cause large oscillations and imbalance given that converters considered as loads have constant power load characteristics. In this work, output DC bus voltage stabilization and current sharing of a multiphase parallel-interleaved-FC boost converter is presented. The proposed robust controller with added integrator action is based on the Hamiltonian–Lyapunov function. The efficacy and robustness of the designed controller were successfully authenticated by experimental results obtained using a 2.5 kW prototype FC converter (via four-phase parallel-interleaved boost converters) and the dSPACE MicroLabBox platform. The main source of the FC is based on a fuel reformer engine that converts fuel methanol and water into H2 gas in a polymer-electrolyte-membrane-FC stack (50 V, 2.5 kW).",

      "abstract": "This article presents a multiphase interleaved boost converter supplied by a fuel-cell (FC)/reformer power source for highly dynamic transportation applications. A control theory based on the Hamiltonian function approach is considered. Using the port-controlled Hamiltonian system, we propose simple solutions to the dynamic performance and convergence problems when an interaction occurs between the power sources and constant power loads. To corroborate the proposed control law, an FC boost converter (2.5-kW two-phase interleaved converter) is used and investigated in the laboratory. The methanol FC system is composed of a fuel reformer reactor that transforms water and methanol liquid fuel into hydrogen gas to a polymer electrolyte membrane FC stack (2.5 kW, 50 V). The studied control approach is realized by digital calculation using a MicroLabBox controller board (dSPACE platform). The simulation using the MATLAB/Simulink program and the experimental results validate that our proposed solution is an excellent control algorithm for highly dynamic power-load cycles.",

      "abstract": "Electric vehicles (EVs) are an important part of future sustainable transportation. The increasing integration of EV charging stations (EVCSs) in the existing power grids requires new scalable control algorithms that maintain the stability and resilience of the grid. Here, we present such a control approach using an averaged port-Hamiltonian (pH) model. In this approach, the underlying switching behavior of the power converters is approximated by an averaged nonlinear system. The averaged models are used to derive various types of stabilizing controllers, including the typically used proportional-integral (PI) controllers. The pH modeling is showcased by means of a generic setup of an EVCS, where the battery of the vehicle is connected to an ac grid via power lines, converters, and filters. Finally, the control design methods are compared for the averaged pH system and validated using a simulation model of the switched charging station.",

      "abstract": "In whole operation procedure, trajectory tracking control for heavy haul train with the time-varying desired speed is investigated in this paper. Taking full advantage of the heavy haul train's facilities, a proportional-integral (PI) control method based on the real-time speed error and the real-time displacement is proposed to represent the dynamic model of heavy haul train as port-Hamiltonian (PH) system framework, which implements the interactive feature of the in-train force and the damping feature of the basic resistance force effectively. Due to the proposed method, the real-time speed of heavy haul train asymptotically tracks the time-varying desired speed and the real-time displacement is small in whole operation procedure. Since the basic resistance force is utilized to construct the non-negative definite matrix and heavy haul train is represented as PH system, the proposed method is also effective for trajectory tracking control of heavy haul train subjected to the uncertain and time-varying basic resistances without parameter adaption or estimation. In short, a universal tracking control scheme is presented for heavy haul train subjected to the aforementioned different operative conditions. Finally, simulations confirm the validity and advantage of the proposed method.",

For this solution, it is proposed to use regulatory actions on directly uncontrollable loops, which can be formed during synthesis and always are discarded due to impossible implementation, by transmitting these actions through controllable loops in two different ways: first — by rebuilding closed-loop PCH to suitable form, second — by correcting reference signal. In order to check existing solutions and verify feasibility and effectiveness of proposed approaches they were used to synthesize ESCSs for a simple direct current drive, which were further investigated. Obtained results confirmed that both approaches allow outmatching existing solutions and having their advantages and disadvantages.",

In particular, the port-Hamiltonian structure of the system suggests the design of a suitable sliding manifold such that the system on this manifold exhibits desired passivity properties. This approach simplifies the control design and relaxes some restrictive assumptions required by other controllers proposed in the literature, while offering satisfactory performance.",

      "abstract": "This paper presents an energy-consistent super-twisting (ST) sliding-mode control design for a single-phase grid-forming inverter with an output LC filter, motivated by inverter-dominated low-inertia power-electronic applications. Throughout, energy-consistent refers to a sliding surface whose closed-loop motion is shaped to avoid large transient excursions of the filter Hamiltonian. The surface couples the voltage error, its integral, and the inductor current, and its design is informed by the port-Hamiltonian (PH) representation of the LC filter; the Hamiltonian is employed as a physically meaningful diagnostic rather than as a strict control structure. A super-twisting reaching law is used to provide continuous control action and finite-time convergence under bounded matched perturbations, with explicit gain conditions stated. An actuator saturation constraint is included in the model and its effect is reported. The proposed controller is benchmarked against a classical first-order SMC with boundary layer on the same sliding surface, isolating the contribution of the ST reaching law. Simulation studies on a grid-forming LC inverter subject to renewable-like disturbances and parameter uncertainties show that the ST controller reduces steady-state tracking error, control chatter, and Hamiltonian variation by a factor of two or more across the tested operating envelope, while the gain-sensitivity coefficient of variation of $\\Delta {\\mathcal{H}}$ stays below 3 over a [0.5,1.5]× nominal gain box.",

      "abstract": "The energy-shaping and maximum torque per ampere (MTPA) principle is used to develop the model and position control of permanent magnet synchronous motor (PMSM) in this paper. Firstly, based on the port-controlled Hamiltonian (PCH) systems theory, a PCH position control model of PMSM is established. Secondly, using energy-shaping and MTPA method, the control strategy of PMSM is presented when load torque is known and unknown. The control problem of the PMSM is reduced to the solution of a partial differential equation. The partial differential equation can be transformed into a set of general differential equation by assigning desired interconnection and damping matrix. Finally, the equilibrium stability is also analyzed. The simulation results show that the proposed scheme exhibits good position control and load disturbances attenuation performances.",

Firstly, two conditions are established to determine whether an ellipsoid is contractively invariant for the systems only with actuator saturation, with which the biggest ellipsoid contained in the domain of attraction can be found and a new estimation method is presented. It is shown that the proposed conditions can be expressed in the form of the linear matrix inequality optimization problem with constraints. Secondly, the obtained conditions are extended to estimate the domain of attraction of the systems subject to both actuator saturation and disturbances, and a new estimation method is proposed. Study of an illustrative example shows that the methods proposed in this paper work very well in estimating the domain of attraction for some classes of nonlinear PCH systems with actuator saturation and/or disturbances.",

First of all, a PCH system model of PMSM is established. Then, using the interconnection and damping assignment method, the PCH controller of the PMSM system is designed when the load torque is known. According to the maximum torque per ampere (MTPA) control rule, the desired equilibrium of the system is obtained. The L2 gain load torque disturbance attenuation technology is applied to the PCH control of PMSM system. Finally, in order to track the changes of the load torque better and eliminate speed steady error, the load torque observer is given. The simulation results show that the proposed scheme has a good performance and practical application prospects.",

From the energy shaping perspective, a port-controlled hamiltonian (PCH) description for the wind energy conversion system (WECS) is obtained. Based on the description and the enegy- matching equation, the proposed switch functions enable us to realize maximum power extraction by tracking equilibrium point in the power optimization stage. This approach possesses the advantages of stable tracking performance and rapid convergence rate. Simulation results via Matlab/Simulink for 2MW WECS with a doubly fed induction generator (DFIG) confirmed its effectiveness.",

The system's modelling and the control synthesis are realised under the port-Hamiltonian formulation. Where a desired form of the closed-loop energy is enforced such that its local equilibrium implies the application of the desired force to the environment (patient's nostril), while regulating the endoscope unconstrained position and orientation inside the nasal cavity. This allows to set a specific energetic relation between the controlled robot and the environment, which in turn means a safer interaction with the tissue. Simulation and experimental results are presented to validate the theoretical concepts.",

A desired state error PCH system structure is assigned to closed-loop control system for the three-phase PWM rectifiers. The desired Hamiltonian function is given based on the energy-shaping theory. The controller is designed through interconnection and damping assignment method. Moreover, a proportional integral (PI) regulation is used to eliminate the steady-state error of the output dc voltage. The simulation results show that the proposed control method has good output voltage tracking control and unity power factor regulation performances.",

      "abstract": "This paper presents an interconnection and damping assignment passivity based control (IDA-PBC) for the position and impedance control of flexible joint robot. In considering of the joint damping and with some simplification of friction, a flexible joint robot system is descripted as an port-controlled Hamiltonian system with dissipation(PCHD). Then, giving a desired Hamiltonian function which both shapes potential and kinetic energies, the control laws of position control and impedance control is derived by the algebraic IDA-PBC method, which preserves the PCHD structure of the close-loop system. Comparing with the traditional passivity based control (PBC), the proposed method gives a new explanation of the control of flexible joint robot by introducing the self-damping and cross-damping terms, which make the gain selecting procedure more intuitive and comfortable. Simulation and experiments are done to verify the proposed controller, and the results shows a promising performance both in position and impedance control.",

      "abstract": "Dual Active Bridge (DAB) converters are pivotal in renewable energy, electric vehicles, and energy storage systems due to bidirectional power transfer, galvanic isolation, and zero-voltage switching capabilities. While Silicon Carbide (SiC) devices enhance efficiency through reduced conduction losses and high-frequency operation, conventional SinglePhase-Shift (SPS) control under non-unity voltage ratios induces excessive circulating power and current stress, degrading system efficiency and reliability. The Brayton-Moser (BM) form provides a powerful nonlinear control method through energy-based port Hamiltonian system modeling. To address the aforementioned issues, this study proposes an enhanced Brayton-Moser theory-based nonlinear control strategy integrated with Dual-Phase-Shift (DPS) modulation and minimum circulating power optimization. To enhance system performance under passive conditions and optimize efficiency, a Brayton-Moser theory-guided DAB-based DC power conversion system has been architected and experimentally substantiated via simulation platforms.",

      "abstract": "In this paper we address the state estimation problem of a particular class of irreversible port Hamiltonian systems (IPHS), which are assumed to be partially observed. Our main contribution consists to design an observer such that the augmented system (plant + observer) is strictly passive. Under some additional assumptions, a Lyapunov function is constructed to ensure the stability of the coupled system. Finally, the proposed methodology is applied to the gas piston system model. Some simulation results are also presented.",

Our simple model focuses on the relevant coupling structures and aims to reduce the unrelated complexity as much as possible. Then, we apply the port-Hamiltonian formalism to this model and its subsystems and investigate the interconnections. Finally, we apply a simple spatial discretization to the system to investigate the properties of the resulting finite-dimensional port-Hamiltonian system and to determine whether the order of coupling and discretization affect the resulting semi-discrete system.",

      "abstract": "The mathematical model of a three-phase voltage source pulse-width modulation (PWM) DC/AC inverter is non-linear, and in view of the traditional linear control strategy it can not meet the requirements of designing a high-performance inverter. What’s more, when the loads are not pure resistive loads, the inverter further requires that the controller possess high-performance. This paper proposes a nonlinear control strategy for the inverter called Passivity-based Control. We can alter the inverter model in three-phase abc coordinate to two-phase synchronous rotating dq coordinate for establishing the port-control Hamiltonian (PCH) model for this system. We can control the distribution of energy in the system to achieve the control aim. Simulation results show that the passivity-based control method can make this system possess a level of high-performance that is both robust and dynamic.",

We show that input-output linearization, passivity-based design, and the theory of port-controlled Hamiltonian systems lead naturally to static output feedback of device charge. This formalizes and extends previously reported results from the MEMS literature. Further analysis suggests that significantly improving transient behavior in lightly damped MEMS requires dynamic estimation of electrode velocity. We implement output-feedback control using a reduced-order nonlinear observer. Simulations predict greatly improved transient behavior, and large reductions in control voltage.",

      "abstract": "It is known that straightforward application of the classical Lagrangian and Hamiltonian formalism to systems with mass varying explicitly with position may lead to discrepancies in the formulation of the equations of motion. Systems with mass varying explicitly with position often arise from situations where the partitioning of a closed system of constant mass leads to open subsystems that exchange mass among themselves. One possible solution is to introduce additional nonconservative generalized forces that account for these effects. However, it remains unclear how to systematically interconnect the Lagrangian or Hamiltonian subsystems. In this note, systems with mass varying explicitly with position and their properties are studied in the port-Hamiltonian modeling framework. The port-Hamiltonian formalism combines the classical Lagrangian and Hamiltonian approach with network modeling and is applicable to various engineering domains. One of the strong aspects of the port-Hamiltonian formalism is that power-preserving interconnections between port-Hamiltonian subsystems results in another port-Hamiltonian system with composite energy and interconnection structure. The motion of a heavy cable being deployed from a reel by the action of gravity is used as an example.",

One advantage of this approach is the simplicity of its implementation, which requires only a velocity observer. Another advantage is its robustness to modeling uncertainties, since it can be calculated independently of the plant structure. A gantry crane is selected as case study, yielding simulation and experimental results that show the good performance of this technique.",

With the aid of analytic tools for large-scale and hybrid systems, this paper proposes two new safety verification methods for power systems. The first method is based on barrier certificates and passivity. This method provides a general safety verification framework for power systems with the port-Hamiltonian structure. The energy shaping technique is also exploited to attain safety conditions for controlled port-Hamiltonian systems. The second method, based on positive invariance, yields exact safety verification for power systems based on linearized models, particularly linear Hamiltonian systems. Decidability of exact safety verification is established via algebraic and positive invariance approaches; other analytic and numerical issues are addressed from the positive invariance perspective.",

      "abstract": "This paper presents the modelling of an actuator based on Magnetic Shape Memory Alloys (MSMA). The actuation principle relies on the ability of the material to change its shape under the application of a magnetic field. Previous models proposed by authors were based on canonical (symplectic) Hamiltonian modeling and thermodynamics of irreversible processes. These models, though physically cogent, are non-minimal differential algebraic dynamical models and hence less adapted for control purposes. This paper therefore proposes a modified and system-oriented modeling procedure which lends itself naturally to a port-Hamiltonian model. The latter is found to be a minimal realization of the above whereby interconnection between subsystems is clearly visible. Using Lagrange multipliers, constraints which arise due to causality and interconnection are expressed. In the last section, Differential Algebraic Equations (DAE) resulting from previous models are reduced to Ordinary Differential Equations (ODE) and by using coordinate transformations, constraints are decoupled from the system input/output. The resulting model is well-suited for control.",

      "abstract": "While mechanical, electrical and electromechanical systems may exhibit complex nonlinear dynamics, their behavior is typically governed by relatively simple underlying principles of energy transfer. Modeling methodologies that seek to capture this underlying order give rise to a special form of the equations of motion, called a port controlled Hamiltonian structure with damping (PCHD). Often the natural behavior of a system is unacceptable for a desired application, and must be modified. A body of work on passivity-based control exists that shows how to use Casimir functions—certain invariant quantities of the open-loop PCHD—to reshape the natural dynamics in a desired way. We seek to apply this approach to an electrostatically-actuated MEMS device subject to the saddle-node bifurcation known as snap-through. We show that the equations describing this system do not have an appropriate Casimir function, but that they can be suitably modified through an implementable output feedback. We fully characterize the Casimirs of the modified system, and show how they may be used to eliminate snap-through. Unfortunately the transient behavior of the resulting closed-loop system is governed by the damping of the mechanical subsystem, which may or may not provide adequate performance.",

A physics informed neural network (PINN) is constructed by embedding PH structural constraints into a Neural ODE architecture, so that the system matrices can be learned while preserving key physical properties, including symmetry, positive definiteness, and dissipativity. Utilizing the extracted dynamic parameters, an interconnection and damping assignment passivity-based control (IDA-PBC) law is synthesized to execute precise USV trajectory tracking. To validate the proposed methodology, a numerical simulation test is conducted. The findings confirm that our network successfully identifies the core physical characteristics, which in turn empowers the controller to track circular references robustly, even in the presence of parameter mismatches.",

Traditional passivity-based methods often assume full state availability and matched disturbances, limiting their applicability in uncertain, sensor-constrained environments. This study proposes a learning-augmented interconnection and damping assignment passivity-based control (iIDA–PBC) framework that enhances robustness and adaptability for UMSs. The approach integrates real-time disturbance estimation using Gaussian Math. Comput. Appl. (GPR) and Math. Comput. Appl. (LSTM) networks, alongside nonlinear observer designs for reconstructing unmeasured actuator states. The overall control architecture preserves the port-Hamiltonian structure while enabling adaptive compensation for unknown external perturbations. Theoretical analysis ensures Math. Comput. Appl. (ISS) under bounded estimation errors. Simulation results on a benchmark underactuated system demonstrate improved disturbance rejection, tracking accuracy, and robustness compared to conventional adaptive and passivity-based controllers. The proposed method is suitable for complex, partially observable systems such as aerial vehicles, autonomous robots, and marine platforms.",

We describe some constructions—Courant algebroids and Dirac structures—from the so-called generalized geometry. They prove to be a convenient language for studying the internal structure of the differential equations of port-Hamiltonian and implicit Lagrangian systems, which describe dissipative or coupled mechanical systems and systems with constraints, respectively. For both classes of systems, we formulate some open problems that can be solved using computer algebra tools and methods. We also recall the definitions of graded manifolds and Q ‑structures from graded geometry. On particular examples, we explain how classical differential geometry is described in the framework of the graded formalism and what related computational questions can arise. This direction of research is apparently an almost unexplored branch of computer algebra.",

      "abstract": "Abstract In this article we study the possibilities of recovering the structure of port-Hamiltonian systems starting from “unlabelled” ordinary differential equations describing mechanical systems. The algorithm we suggest solves the problem in two phases. It starts by constructing the connectivity structure of the system using machine learning methods – producing thus a graph of interconnected subsystems. Then this graph is enhanced by recovering the Hamiltonian structure of each subsystem as well as the corresponding ports. This second phase relies heavily on results from symplectic and Poisson geometry that we briefly sketch. And the precise solutions can be constructed using methods of computer algebra and symbolic computations. The algorithm permits to extend the port-Hamiltonian formalism to generic ordinary differential equations, hence introducing eventually a new concept of normal forms of ODEs.",

This Dirac structure is a subspace of a Hilbert space. Naturally, associated with this Dirac structure is an infinite-dimensional system. We parameterize the boundary port variables for which the $ C_{0} $-semigroup associated with this system is contractive or unitary. Furthermore, this parameterization is used to split the boundary port variables into inputs and outputs. Similarly, we define a linear port controlled Hamiltonian system associated with the previously defined Dirac structure and a symmetric positive operator defining the energy of the system. We illustrate this theory on the example of the Timoshenko beam.",

The starting point of the control design is modeling for control. We do this in the framework of port-Hamiltonian (pH) modeling, which has favorable properties, such as passivity and a Hamiltonian representing the energy and serving as a Lyapunov function, that can be exploited for controller design. An important property of the pH modeling framework is that it facilitates modeling multiphysics systems or systems which consist of several subsystems, where all parts are modeled separately and then can be interconnected easily. This is possible because any interconnection of finite dimensional pH systems yiel...",

Through an early lumping approach we extend the control by interconnection and energy shaping approach to the use of distributed control over the spatial domain. With the established finite dimensional controller, the closed-loop performances can be modified over a given range of frequencies while guaranteeing the closedloop stability of the infinite dimensional system. Two cases are investigated, the ideal case where the controller acts on the complete spatial domain (infinite dimensional distributed control), and the more realistic one where the control is piecewise homogeneous (finite rank distributed control). The proposed control strategies are illustrated through simulations on the stabilization of a vibrating Timoshenko",

This model can then be used to design a controller for the shape of the inflatable structure. Inflatable structures have very nice properties, suitable for aerospace applications, e.g., inflatable space reflectors. With this technology we can build inflatable reflectors which are about 100 times bigger than solid ones. But to be useful for telescopes we have to achieve the desired surface accuracy by actively controlling the surface of the inflatable. The starting point of the control design is modeling for control. In this paper we choose lumped pH modeling since these models offer a clear structure for control design. To be able to design a finite dimensional controller for the infinite dimensional system we need a finite dimensional approximation of the infinite dimensional system which inherits all the structural propert...",

      "abstract": "We develop a new approach to the construction of state vectors for linear time-invariant systems described by higher-order differential equations. The basic observation is that the concatenation of two solutions of higher-order differential equations results in another (weak) solution once their remainder terms resulting from (repeated) integration by parts match. These remainder terms can be computed in a simple and efficient manner by making use of the calculus of bilinear differential forms and two-variable polynomial matrices. Factorization of the resulting two-variable polynomial matrix defines a state map, as well as a state map for the adjoint system. Minimality of these state maps is characterized. The theory is applied to three classes of systems with additional structure, namely self-adjoint Hamiltonian, conservative port-Hamiltonian, and time-reversible systems. For the first two classes it is shown how the factorization leading to a (minimal) state map is equivalent to the factorization of another two-variable polynomial matrix, which is immediately derived from the external system characterization, and defines a symplectic, respectively, symmetric, bilinear form on the minimal state space.",

Basic idea is to associate with the incidence matrix of the graph a Dirac structure relating the flow and effort variables associated to the edges, internal vertices, as well as boundary vertices of the graph, and to formulate energy-storing or energy-dissipating relations between the flow and effort variables of the edges and internal vertices. This allows for state variables associated to the edges, and formalizes the interconnection of networks. Examples from different origins such as consensus algorithms are shown to share the same structure. It is shown how the identified Hamiltonian structure offers systematic tools for the analysis of the resulting dynamics.",

Such an identified molecular dynamics, called renormalized molecular dynamics, is used for fast numerical calculations as well as for modeling large targets, even though the numerical molecular dynamics calculations are very time-consuming. The coarse graining can be described as a parameter scaling in the Hamiltonian system of renormalized molecular dynamics, and thus a renormalized Hamiltonian system can be defined by the scalable Hamiltonian. At the inverse limit of the coarse graining, the renormalized Hamiltonian system can be transformed into a distributed port-Hamiltonian system that is a formal representation of partial differential equations for boundary controls based on energy flows. By introducing the concept of the controls to each coarse graining level, the renormalized Hamiltonian systems can be used as a scalabl...",

      "abstract": "A distributed port-Hamiltonian (DPH) system is a framework of boundary controls based on energy for partial differential equations (PDEs). A DPH system is defined in terms of a Stokes--Dirac structure that implies boundary integrability in the sense of Stokes' theorem. Because of the boundary integrability, the energy flows of the systems distributed on a domain can be transformed into energy flows across the boundary of the domain. In general, there might exist boundary nonintegrable energy flows in PDEs. Such energy flows can be modeled by an extended representation of DPH systems, called a distributed energy flow. This paper shows that DPH systems with distributed energy flows can be transformed into standard DPH systems without distributed energy flows by adding extra DPH systems. As a result, we can apply boundary controls and boundary interconnections based on energy to a larger class of PDEs. We call this transformation the boundary completion of DPH systems. This paper derives the necessary and su...",

A typical situation is when (part of) the system is obtained from the spatial discretization of an infinite dimensional port-Hamiltonian system: in this case, the dynamics is not given in standard input-state-output form, but as a set of DAEs. Consequently, the control by energy-shaping has to be extended to deal with dynamical systems with constraints. The general methodology is discussed with the help of a simple but illustrative example, i.e. a transmission line interconnected with an RLC circuit.",

Generation and stability results already known for linear feedback are extended to nonlinear dissipative feedback, both to static feedback control and dynamic control via an (exponentially stabilising) nonlinear controller. A design method for nonlinear controllers of linear port-Hamiltonian systems is introduced. As a special case the Euler-Bernoulli beam is considered.",

      "abstract": "This paper presents a structure-preserving model reduction approach applicable to large-scale, nonlinear port-Hamiltonian systems. Structure preservation in the reduction step ensures the retention of port-Hamiltonian structure which, in turn, assures the stability and passivity of the reduced model. Our analysis provides a priori error bounds for both state variables and outputs. Three techniques are considered for constructing bases needed for the reduction: one that utilizes proper orthogonal decompositions; one that utilizes $\\mathcal{H}_2/\\mathcal{H}_{\\infty}$-derived optimized bases; and one that is a mixture of the two. The complexity of evaluating the reduced nonlinear term is managed efficiently using a modification of the discrete empirical interpolation method (DEIM) that also preserves port-Hamiltonian structure. The efficiency and accuracy of this model reduction framework are illustrated with two examples: a nonlinear ladder network and a tethered Toda lattice.",

      "abstract": "Dissipative Hamiltonian (DH) systems are an important concept in energy based modeling of dynamical systems. One of the major advantages of the DH formulation is that system properties are encoded in an algebraic way. For instance, the algebraic structure of DH systems guarantees that the system is automatically stable. In this paper the question is discussed when a linear constant coefficient DH system is on the boundary of the region of asymptotic stability, i.e., when it has purely imaginary eigenvalues, or how much it has to be perturbed to be on this boundary. For unstructured systems this distance to instability (stability radius) is well understood. In this paper, explicit formulas for this distance under structure-preserving perturbations are determined. It is also shown (via numerical examples) that under structure-preserving perturbations the asymptotical stability of a DH system is much more robust than under general perturbations, since the distance to instability can be much larger when struc...",

Important properties like conservation of mass, dissipation of energy, passivity, existence of steady states, and exponential stability can be preserved by an appropriate semidiscretization in space via a mixed finite element method and also during the further dimension reduction by structure- preserving Galerkin projection, which is the main focus of this paper. Krylov subspace methods are employed for the construction of the reduced models, and we discuss certain modifications needed to satisfy some algebraic compatibility conditions which are required to ensure the well-posedness of the reduced models and the preservation of the key properties. Our arguments are based on a careful analysis of the underlying infinite dimensional problem and its Galerkin approximations. The proposed algorithms therefore have a direct inte...",

In this paper, we consider the problem of finding the nearest positive real (PR) system to a non-PR system: given an LTI control system defined by $E \\dot{x}=Ax+Bu$ and $y=Cx+Du$, minimize the Frobenius norm of $(\\Delta_E,\\Delta_A,\\Delta_B,\\Delta_C,\\Delta_D)$ such that $(E+\\Delta_E,A+\\Delta_A,B+\\Delta_B,C+\\Delta_C,D+\\Delta_D)$ is a PR system. We first show that a system is extended strictly PR if and only if it can be written as a strict port-Hamiltonian system. This allows us to reformulate the nearest PR system problem into an optimization problem with a simple convex feasible set. We then use a fast gradient method to obtain a nearby PR system to a given non-PR system and illustrate the behavior of our algorithm with several examples. This is, to the best of our knowledge, the first algorithm that computes a nearby PR system to a given non-PR sys...",

      "abstract": "A wide class of matrix pencils connected with dissipative Hamiltonian descriptor systems is investigated. In particular, the following properties are shown: all eigenvalues are in the closed left half plane, the nonzero finite eigenvalues on the imaginary axis are semisimple, the index is at most two, and there are restrictions for the possible left and right minimal indices. For the case that the eigenvalue zero is not semisimple, a structure-preserving method is presented that perturbs the given system into a Lyapunov stable system.",

      "abstract": "We introduce a novel model order reduction (MOR) method for large-scale linear switched systems (LSS) where the coefficient matrices are affected by a low-rank switching. The key idea is to replace the LSS by a nonswitched system with extended input and output vectors---called the envelope system---which is able to reproduce the dynamical behavior of the original LSS by applying a certain feedback law. The envelope system can be reduced using standard MOR schemes and then transformed back into an LSS. Furthermore, we present an upper bound for the output error of the reduced-order LSS and show how to preserve quadratic Lyapunov stability. The approach is tested by means of a numerical example demonstrating the efficacy of the presented method.",

We show that the realization with a maximal passivity radius is a normalized port-Hamiltonian one. Its computation is linked to a particular solution of a linear matrix inequality that defines passivity of the transfer function, and we provide an algorithm to construct this optimal solution. We also consider the problem of finding the nearest passive system to a given non-passive one and provide a simple but suboptimal solution.",

We perform a backward error analysis and show that for matrix pencils associated with port-Hamiltonian descriptor systems and a given computed eigenstructure with the correct symmetry structure there always exists a nearby port-Hamiltonian descriptor system with exactly that eigenstructure. We also derive bounds for how near this system is and show that the stability radius of the system plays a role in that bound.",

It is shown that the Riesz basis property is equivalent to the fact that system operator generates a strongly continuous group. Moreover, in this situation the spectrum consists of eigenvalues only, located in a strip parallel to the imaginary axis and they can decomposed into finitely many sets having each a uniform gap.",

Inspired by the geometric approach of Maschke and van der Schaft and the linear algebraic approach of Mehl, Mehrmann and Wojtylak, we present another view by using the theory of linear relations. We show that this allows to elaborate the differences and mutualities of the geometric and linear algebraic views, and we introduce a class of DAEs which comprises these two approaches. We further study the properties of matrix pencils arising from our approach via linear relations.",

      "abstract": "Model order reduction (MOR) methods that are designed to preserve structural features of a given full order model (FOM) often suffer from a lower accuracy when compared to their non-structure-preserving counterparts. In this paper, we present a framework for structure-preserving MOR, which allows to compute structured reduced order models (ROMs) with a much higher accuracy. The framework is based on parameter optimization, i.e., the elements of the system matrices of the ROM are iteratively varied to minimize an objective functional that measures the difference between the FOM and the ROM. The structural constraints can be encoded in the parametrization of the ROM. The method only depends on frequency response data and can thus be applied to a wide range of dynamical systems. We illustrate the effectiveness of our method on a port-Hamiltonian and on a symmetric second-order system in a comparison with other structure-preserving MOR algorithms.",

      "abstract": "We introduce optimal energy shaping as an enhancement of classical passivity-based control methods. A promising feature of passivity theory, alongside stability, has traditionally been claimed to be intuitive performance tuning along the execution of a given task. However, a systematic approach to adjust performance within a passive control framework has yet to be developed, as each method relies on few and problem-specific practical insights. Here, we cast the classic energy-shaping control design process in an optimal control framework; once a task-dependent performance metric is defined, an optimal solution is systematically obtained through an iterative procedure relying on neural networks and gradient-based optimization. The proposed method is validated on state-regulation tasks.",

      "abstract": "We consider the singular optimal control problem of minimizing the energy supply of linear dissipative port-Hamiltonian descriptor systems subject to control and terminal state constraints. To this end, after reducing the problem to an ODE with feed-through term, we derive an input-state turnpike towards a subspace for optimal control of generalized port-Hamiltonian ordinary differential equations. We study the reachability properties of the system and prove that optimal states exhibit a turnpike behavior with respect to the conservative subspace. By means of the port-Hamiltonian structure, we show that, despite control constraints, this turnpike property is global in the initial state. Further, we characterize the class of dissipative Hamiltonian matrices and pencils.",

      "abstract": "We analyze when an arbitrary matrix pencil is equivalent to a dissipative Hamiltonian pencil and show that this heavily restricts the spectral properties. In order to relax the spectral properties, we introduce matrix pencils with coefficients that have positive semidefinite Hermitian parts. We will make a detailed analysis of their spectral properties and their numerical range. In particular, we relate the Kronecker structure of these pencils to that of an underlying skew-Hermitian pencil and discuss their regularity, index, numerical range, and location of eigenvalues. Further, we study matrix polynomials with positive semidefinite Hermitian coefficients and use linearizations with positive semidefinite Hermitian parts to derive sufficient conditions for a spectrum in the left half plane and derive bounds on the index.",

The proofs are based on a structural observation that the port-Hamiltonian operator can be transformed to the derivative on a familiy of reference intervals by suitable congruence relations allowing for studying the simpler case of a transport equation. Moreover, we provide well-posedness results for associated control problems without assuming any additional regularity of the operators involved.",

      "abstract": "We discuss different cases of dissipative Hamiltonian differential-algebraic equations and the linear algebraic systems that arise in their linearization or discretization. For each case we give examples from practical applications. An important feature of the linear algebraic systems is that the (non-Hermitian) system matrix has a positive definite or semidefinite Hermitian part. In the positive definite case we can solve the linear algebraic systems iteratively by Krylov subspace methods based on efficient three-term recurrences. We illustrate the performance of these iterative methods on several examples. The semidefinite case can be challenging and requires additional techniques to deal with\"singular part\", while the\"positive definite part\"can still be treated with the three-term recurrence methods.",

      "abstract": "We derive a minimal port-Hamiltonian formulation of a general class of interacting particle systems driven by alignment and potential-based force dynamics which include the Cucker-Smale model with potential interaction and the second order Kuramoto model. The port-Hamiltonian structure allows to characterize conserved quantities such as Casimir functions as well as the long-time behaviour using a LaSalle-type argument on the particle level. It is then shown that the port-Hamiltonian structure is preserved in the mean-field limit and an analogue of the LaSalle invariance principle is studied in the space of probability measures equipped with the 2-Wasserstein-metric. The results on the particle and mean-field limit yield a new perspective on uniform stability of general interacting particle systems. Moreover, as the minimal port-Hamiltonian formulation is closed we identify the ports of the subsystems which admit generalized mass-spring-damper structure modelling the binary interaction of two particles. Using the information of ports we discuss the coupling of difference species in a port-Hamiltonian preserving manner.",

Interpolatory necessary optimality conditions for [Formula: see text]-optimal reduced-order modeling of unstructured linear time-invariant (LTI) systems are well-known. Based on previous work on [Formula: see text]-optimal reduced-order modeling of stationary parametric problems, in this paper, we develop and investigate optimality conditions for [Formula: see text]-optimal reduced-order modeling of structured LTI systems, in particular, for second-order, port-Hamiltonian, and time-delay systems. Under certain diagonalizability assumptions, we show that across all these different structured settings, bitangential Hermite interpolation is the common form for optimality, thus proving a unifying optimality framework for structured reduced-order modeling.",

      "abstract": "One of the key contributions of the 1972 seminal paper by Willems was the analysis of symmetry (also called reciprocity) of input-state-output systems, both from an external (input-output) and internal (state) point of view. The developed theory also included the combination of reciprocity with passivity, and the consideration of relaxation systems, which are passive reciprocal systems without any oscillatory behavior. The paper was motivated from a fundamental system-theoretic point of view (how is external structure reflected into internal structure), as well as by a wide range of application areas, including electrical network synthesis, thermodynamics, and viscoelastic materials. On the other hand, the obtained results are for linear systems, and the extension to the nonlinear case, even for subclasses of nonlinear systems, is far from trivial. The present paper aims at taking some steps into this direction.",

To this end, we utilize the associated exergy, a function that is composed of the system’s Hamiltonian and entropy, to prove global existence in time for bounded control functions. Then, we rigorously verify our existence conditions for two examples, the gas-piston system and a network of heat exchangers. Last, we explore model predictive control tailored to irreversible port-Hamiltonian systems by means of a numerical case study with a heat exchanger network.",

      "abstract": "The purpose of this paper is to show how the Timoshenko beam can be fruitfully described within the framework of distributed port Hamiltonian (dpH) systems so that rather simple and elegant considerations can be drawn regarding both the modeling and control of this mechanical system. After the dpH model of the beam is introduced, the control problem is discussed. In particular, it is shown how control approaches already presented in the literature can be unified, and a new control methodology is presented and discussed. This control methodology relies on the generalization to infinite dimensions of the concept of structural invariant (Casimir function) and on the extension to distributed systems of the so-called control by interconnection methodology. In this way, finite dimensional passive controllers can stabilize distributed parameter systems by shaping their total energy, i.e., by assigning a new minimum in the desired equilibrium configuration that can be reached if a dissipative effect is introduced.",

      "abstract": "In the present paper we elaborate on the underlying Hamiltonian structure of interconnected energy-conserving physical systems. It is shown that a power-conserving interconnection of port-controlled generalized Hamiltonian systems leads to an implicit generalized Hamiltonian system, and a power-conserving partial interconnection to an implicit port-controlled Hamiltonian system. The crucial concept is the notion of a (generalized) Dirac structure, defined on the space of energy-variables or on the product of the space of energy-variables and the space of flow-variables in the port-controlled case. Three natural representations of generalized Dirac structures are treated. Necessary and sufficient conditions for closedness (or integrability) of Dirac structures in all three representations are obtained. The theory is applied to implicit port-controlled generalized Hamiltonian systems, and it is shown that the closedness condition for the Dirac structure leads to strong conditions on the input vector fields.",

      "abstract": "Power systems, including synchronous generator systems, are typical systems that strive for stable operation. In this paper, we numerically study the fault transient process of a synchronous generator system based on the first benchmark model. That is, we make it clear whether an originally stable generator system can restore its stability after a short time of unstable transient process. To achieve this, we construct a structure-preserving method and compare it with the existing and frequently-used predictor–corrector method. We newly establish a reductive form of the circuit system and accelerate the reduction process. Also a switching method between two stages in the fault transient process is given. Numerical results show the effectiveness and reliability of our method.",

      "abstract": "Safety analysis is important when designing and developing cyber-physical systems (CPS). An autonomous vehicle can be described as a complex CPS where the physical dynamics of the vehicle interact with the control systems. The challenge is ensuring safety despite nonlinearities, hybrid dynamics, and disturbances as well as complex cyber-physical interactions. In this paper, we present an approach for the safety analysis of automotive control systems using multimodal port-Hamiltonian systems (PHS). The approach uses the Hamiltonian function to represent the energy of the safe and unsafe states and employs passivity to prove that trajectories that begin in safe regions cannot enter unsafe regions. We first apply the approach to the safety analysis of a longitudinal vehicle dynamics composed with an adaptive cruise control (ACC) system. We then extend the results to the safety analysis of a combined longitudinal and lateral vehicle dynamics composed with an ACC and lane keeping control (LKC) system. Simulation results are presented to demonstrate the approach.",

      "abstract": "This work presents a dynamic model of V-shaped thermal actuator using an assumption that all beams are considered to be homogeneous and the heat source is evenly distributed on those beams. Furthermore, the control scheme of this system is proposed from the view point of partial derivative equations (PDE) and separation method. The offline simulation results show that the outgoing parameters reflect exactly the physical nature of the subject and they are suitable with the simulation outcomes in the software Ansys. The work outcome would be a foundation for the model development and control design problem for micro motors using thermal expansion effects.",

      "abstract": "Medical trainees are required to acquire sufficient skills before touching a real patient. Nowadays, haptic simulators provide an effective solution but they do not facilitate an active supervision by a trainer who should show the right gestures in terms of motions and forces to apply, in the simulated environment. Dual user training systems aim at this purpose. Even though they permit a cooperative training, they generally dot not enable efficient demonstration/evaluation modes where the user who observes the person performing a manipulation is also able to feel the interaction forces, not only the motion. We earlier introduced the Energy Shared Control (ESC) architecture aiming at providing the latter function. It is modeled with the Port Hamiltonian framework and it embeds a Time Domain Passivity Controller, to compose a one degree-of-freedom (dof) dual-user haptic system for hands-on training. In this paper, we extend it to three dof with three identical haptic devices. Experiments bring information about its performance.",

      "abstract": "Autonomous underwater vehicles (AUVs) have become an important tool for marine scientific research, and their intelligent control technology has also received widespread attention. This paper proposes a finite-time asymptotic stabilization control scheme via the Hamiltonian method for 3D trajectory tracking of AUV with time-varying external disturbances. We can effectively avoid the drawback of approximate linearization by using orthogonal decomposition technology to transform the AUV trajectory tracking mathematical model into a port controlled Hamiltonian (PCH) model. In addition, we design a finite-time trajectory controller for AUVs using the Hamiltonian control theory. This can improve control accuracy by reducing the convergence time of the AUV trajectory tracking system and avoiding overshoot. The theoretical analysis proves the finite-time stability of the AUV 3D trajectory tracking closed-loop control system based on the finite-time Lyapunov stability theory, and the simulation results verify the effectiveness and superiority of the designed control law.",

The desired equilibrium is assigned to the PCH structure model of PMSM by maximum torque per ampere (MTPA) principle, and the desired Hamiltonian function of state error is constructed in the form of fractional power structure as TSM and fast TSM, respectively. Finite-time TSM and fast TSM controllers are designed via interconnection and damping assignment passivity-based control (IDA-PBC) methodology, respectively, and the finite-time stability of the desired equilibrium point is also achieved under the PCH framework. Simulation results validate the improved performance of the presented scheme.",

Firstly, two PCH systems are studied. Using the dissipative Hamiltonian structural properties, the systems are combined to generate an augmented PCH system. When there are external disturbances in the systems, a robust controller with parameters is designed for the systems. Secondly, an algorithm for solving parameters of the controller is proposed with symbolic computation. Finally, an illustrative example is presented to show that the RSS controller obtained in this paper works very well.",

      "abstract": "The characterization of a class of electrical circuits is carried out in terms of both stability properties and steady-state behavior. The main contribution is the interpretation of the electrical topology (how the elements that conform the circuits are interconnected) in terms of mathematical properties derived from the structure of their models. In this sense, at what extent the topology by itself defines the dynamic behavior of the systems is explained. The study is based on the graph theory allowing capturing, departing from the well-known Kirchhoff laws, the topology of the circuits into several matrices with specific structure. The algebraic analysis of these matrices permits identifying conditions that determine whether the system is stable in the sense of Lyapunov and the kind of steady-state behavior that it exhibits. The approach is mainly focused on typical topologies widely used in practice, namely, radial, ring, and mesh networks.",

      "abstract": "This paper investigates the control problem of magnetic levitation system, in which velocity feedback signal is influenced by stochastic disturbance. Firstly, single‐degree‐freedom magnetic levitation is regarded as an energy‐transform action device. From the view of energy‐balance relation, the magnetic levitation system is transformed into port‐controlled Hamiltonian system model. Next, based on the Hamiltonian structure, the control law of magnetic levitation system is designed by applying Lyapunov theory. Finally, the simulation verifies the correctness of the proposed results.",

      "abstract": "In order to achieve better motion accuracy and higher robustness of the shipborne rocket launcher position servo system driven by a permanent magnet synchronous motor (PMSM), a passivity‐based controller based on active disturbance rejection control (ADRC) optimized by improved particle swarm optimization‐back propagation (IPSO‐BP) algorithm is proposed in this paper. The convenient method of interconnection and damping assignment and passivity‐based control (IDA‐PBC) is adopted to establish the port controlled Hamiltonian system with dissipation (PCHD) model of PMSM. To further enhance the robustness and adaptability of traditional ADRC, an BP algorithm is introduced to on‐line update the proportional, integral, and derivative gains of ADRC. Furthermore, to improve the learning capability, the improved PSO algorithm is adopted to optimize the learning rates of the back propagation neural networks. The results of numerical simulation and prototype test indicate that the proposed IPSO‐BP‐ADRC‐PBC controller has better static and dynamic performance than the ADRC‐PBC and BP‐ADRC‐PBC controller with fixed learning rate.",

The PCH model of three degrees of freedom for USV kinetics system is established. By the ES principle, interconnection assignment and damping injection method is applied to the speed and heading control of the closed-loop USV system to realize an overall stability of control mechanism. Simulation results show that the validity and stability of control algorithm can be satisfied with the performance in speed and heading tracking of which the high simplification and portability make it applicable to the various region.",

A time‐varying impedance controller is designed based on this new framework. The time‐varying impedance control method is an extension of conventional impedance control and overcomes the singularity problem that existed in the traditional form of energy tank. The validity of the controller designed in this paper is shown by numerical examples. The simulation results show that the proposed controller can not only eliminate the singularity problem but can also improve the control performance.",

      "abstract": "This work investigates the finite-time control problem for a nonlinear four-tank cross-coupled liquid level system by the port-controlled Hamiltonian (PCH) model. A fixed-free methodology is exhibited which can be used to simplify the controller design procedure. To get an adjustable convergent gain of the finite-time control, a feasible technique named damping normalization is proposed. A novel parameter autotuning algorithm is given to clarify the principle of choosing parameters of the PCH method. Furthermore, a finite-time controller is designed by a state-error desired Hamiltonian function, and the relationship between the settling time and a parameter is given, which can be applied in practical engineering easily to adjust the settling time according to the industrial need. Finally, simulation and experimental results verify the effectiveness of the proposed algorithm.",

      "abstract": "<p>In this paper, a finite-time simultaneous stabilization problem is investigated for a set of stochastic port-controlled Hamiltonian (PCH) systems over delayed and fading noisy channels. The feedback control signals transmitted via a communication network suffer from both constant transmission delay and fading channels which are modeled as a time-varying stochastic model. First, on the basis of dissipative Hamiltonian structural properties, two stochastic PCH systems are combined to form an augmented system by a single output feedback controller and then sufficient conditions are developed for the semiglobally finite-time simultaneous stability in probability (SGFSSP) of the resulting closed-loop systems. The case of multiple stochastic PCH systems is also considered and a new control scheme is proposed for the systems to save costs and achieve computational simplification. Finally, an example is provided to verify the feasibility of the proposed simultaneous stabilization method.</p>",

      "abstract": "A novel energy-based modelling and control strategy is developed and implemented to solve the maximum power point tracking problem when a photovoltaic cell array is connected to consumption loads. A mathematical model that contains key characteristic parameters of an energy converter stage connected to a photovoltaic cell array is proposed and recast using the port-Hamiltonian framework. The system consists of input-output power port pairs and storage and dissipating elements. Then, a current-sensorless control loop for a maximum power point tracking is designed, acting over the energy converter stage and following an interconnection and damping assignment passivity-based strategy. The performance of the proposed strategy is compared to a (classical) sliding mode control law. Our energy-based strategy is implemented in a hardware platform with a sampling rate of 122 Hz, resulting in lower dynamic power consumption compared to other maximum power point tracking control strategies. Numerical simulations and experimental results validate the performance of the proposed energy-based modelling and the novel control law approach.",

      "abstract": "Asynchronous motor system has the characteristics of high order, strong coupling, and nonlinearity. From the dynamical model, it is the underactuated mechanical system, which means that the dimension of its input space is fewer than the degree of freedom. Following this perspective, the energy based nonlinear control technology-CL (controlled Lagrangians) method is used to solve the control problem in this paper. Based on the expected controlled energy and its derivative with respect to time, controlled Lagrangians and generalized force are constructed, and they produce the controlled equations. In order to ensure the complete matching between the controlled equation and the original equation, the gyroscopic forces containing the first-order term of velocity are innovatively introduced into the generalized force, and the matching conditions are obtained. By solving the matching conditions composed of some partial differential equations, the nonlinear smooth feedback control law can realize the global asymptotic stabilization of not only velocity but also position. Finally, the controlled energy is selected as the Lyapunov function, and the stability is proved according to the LaSalle invariant theorem. The effectiveness of the designed control law is demonstrated in the results of the simulation.",

      "abstract": "With the aim of improving the stability of renewable energy system with high permeability in the weak grid, a modified passivity-based control based on interconnection and damping assignment (IDA) is presented for LCL-filtered grid-connected inverters to eliminate the interactive resonances. The object is modeled in the form of port-controller Hamiltonian, including the partial differential of stored energy function. On the premise of ensuring Lyapunov stability, a more flexible interconnection matrix design method is applied to simplify the design process. The closed-loop stability is ensured with the selected Hamiltonian energy function at the desired balanced point. Moreover, a step-by-step design process for damping gains is provided to guarantee stable operation and fast dynamic response under variation of complex grid impedance. With the designed injected damping parameters, considering the effect of delay, it is possible for the real part of the inverter output admittance to be positive within the switching frequency. The performance and robustness of the proposed method for LCL-filtered inverter system are validated via simulated and experimental results under both unbalanced and balanced grid conditions.",

      "abstract": "In this paper, the vehicle ISD (inerter‐spring‐damper) suspension and power‐driven‐damper control strategy are combined to the suspension design, and the power‐driven‐damper semiactive ISD suspension is proposed. The dynamic models of the passive suspension S1 and two semiactive ISD suspensions S2 and S3 are established. Based on the port‐controlled Hamiltonian theory, the power‐driven‐damper semiactive control strategy is designed by analyzing the power transfer of suspension S3. Then, the parameters of the two models are optimized by the particle swarm optimization algorithm, and the optimization results show that the suspension S3 has better performance. The influence of the semiactive damping coefficient, the spring stiffness, and the inertance on the vibration suppression performance is investigated based on the suspension S3. The effect of parameter perturbation on power‐driven‐damper semiactive vehicle ISD suspension illustrates that the designed semiactive vehicle ISD suspension has better ride comfort in a wider range frequency and good robust performance.",

      "abstract": "Credible control and overall stabilization of closed-loop nonlinear systems presented in a port-controlled hamiltonian structure (PCH-D) were forever the development of the simultaneous interconnection and damping assignment passivity-based control (SIDA-PBC) method. The robustness and reliability of the method called into question against noise and certainly modelling errors. Indeed, a new scheme has been presented to control a doubly fed induction generator (DFIG) based on the energy form and exploiting the electrical parameters of the closed loop system. The results obtained provide a new technique and implement more freedom when designing the diagram of the advanced controller during the production of active power. The contribution of this paper is researching on the advanced nonlinear methodes used, many simulations were carried out in simulation using the MATLAB/Simulink environment under important operating conditions, allowing to demonstrate the feasibility of the proposed method and verify the performance considering the robustness.",

      "abstract": "This paper presents a novel structure combining the port-controlled Hamiltonian (PCH) and Backstepping (BS) nonlinear control for the vector control of the six-phase induction motor (SPIM). In this new scheme, to improve the outer loop’s robustness, the BS technique using the integral tracking errors action is proposed in the speed and flux controllers design. The advantage of this proposed control law is not to increase the complexity of differential equation resolution due to being not increased system states numbers. To enhance more the performance of SPIM drives (SPIMD), port-controlled Hamiltonian (PCH) scheme is used in the inner current loop controllers. In this proposed PCH current controller, the stabilization of controller is achieved via system passivity. In that, the interconnection and damping matrix functions of PCH system are shaped so that the physical (Hamiltonian) system structure is preserved at the closed loop level and the closed loop energy function is equal to the difference between the physical energy of the system and the energy supplied by the controller. The proposed control design is based on combination PCH and BS techniques improve significantly performance and robustness. The proposed speed control scheme is validated by Matlab-Simulink software.",

      "abstract": "This paper presents an extension work on the application of interconnection and damping assignment passivity-based controller (IDA-PBC) from the conventional H-bridge inverter to a 5-level Cascaded H-bridge Multilevel Inverter (CHMI). With the controller, the inductor current and the voltage capacitor track the desired reference of the inverter to ensure that the output voltage maintains its regulation while the Total Harmonic Distortion (THD) is kept at low levels with fast transient response. It is designed based on the Port-Control Hamiltonian theory exploiting the dissipation properties of the averaged model of inverter circuits.  The results obtained have proven that the IDA-PBC previously developed for the H-bridge inverter can be easily extended and applied to the CHMI circuit. The simulation results showed that the IDA-PBC is able to maintain the output voltage regulation in both circuits in the case of no-load to full-load condition, load uncertainty, and structural uncertainty while maintaining THD of less than 5%. However, in all cases, CHMI has shown better performance in terms of THD percentage and transient response compared to the H-bridge inverter, which are 290 µs and 150 µs respectively.",

In this article, we propose some predictor-corrector methods and structure-preserving methods for a generator system based on the first benchmark model of subsynchronous resonance, among which the structure-preserving methods preserve a Dirac structure associated with the so-called port-Hamiltonian descriptor systems. To illustrate this, the simplified generator system in the form of index-1 differential-algebraic equations has been derived. Our analyses provide the global error estimates for a special class of structure-preserving methods called Gauss methods, which guarantee their superior performance over the PSCAD/EMTDC and the predictor-corrector methods in terms of computational stability. Numerical simulations are implemented to verify the effectiveness and advantages of our methods.",

      "abstract": "This paper concerns the problem of finite-time stabilization of nonlinear port-controlled Hamiltonian systems subject to nonvanishing disturbances via a composite control manner. The composite controller is developed by combining the damping injection, the finite-time feedback control and the finite-time disturbance observer techniques. The key idea is that a finite-time disturbance observer is designed to estimate disturbances and the estimation of disturbances is employed to feedforward compensate the disturbances. Finite-time stability analysis for the augmented system is presented. An example of a nonlinear circuit system with simulation results demonstrates the effectiveness of the proposed method.",

      "abstract": "In this paper, the control of a type of uncertain time-varying port-controlled Hamiltonian (PCH) systems is investigated. As a matter of fact, the control method proposed in this paper is not based on passivity of PCH systems, but a general output equation is introduced inspired by the measured “information” in the systems in traditional control system theory and the problem of output feedback is considered. In this paper, a conception of p-quadratic stability of the type of PCH system is introduced, and the relationship between p-quadratic stability and Lyapunov stability is pointed out. Then, the problem for p-quadratic stabilization of the proposed system via static output feedback is solved in the following two cases, respectively. For the case of unperturbed output equation, a necessary and sufficient condition for the problem is derived in terms of two groups of linear matrix inequalities (LMIs); for the general case that the output equation also has time-varying perturbations, a sufficient condition for p-quadratic stable of closed-loop system is also given in terms of LMIs. It is also shown that conservatism can be greatly reduced when the perturbation variables in the uncertain PCH systems are restricted to vary within certain intervals. Finally, a numerical example is proposed in the end followed by a simulation to verify the effectiveness of the method proposed in this paper.",

The approach taken introduces the concept of an image effort and provides an interpretation of energy exchange between the dynamics of the physical system and virtual potentials or ‘image Hamiltonians’ posed in the image space. The port-Hamiltonian framework leads to an elegant algorithm to estimate unknown image depth on-line even when the translational velocity of the camera is not measured.",

      "abstract": "The current study presents a robust sensorless control using passivity based control (PBC) combined with high gain observer (HGO). The proposed controller is applied to control the generated doubly-fed induction generator (DFIG) active and reactive power installed on a variable speed wind energy conversion system. The control objective is used to regulate independently the DFIG stator active and reactive power, which are decoupled by using the field oriented control technique. Additionally, this process leads to reduce the cost of control scheme by eliminating the speed sensor. Firstly, the DFIG is modeled under the port controlled Hamiltonian (PCH) model, as well as the method of simultaneous injection damping. Then, the DFIG is further modeled by assignment passivity based on the simultaneous injection damping and assignment (SIDA-PBC) control of the obtained model under such conditions and a comparison with the fuzzy sliding mode controller is carried out. Furthermore, the HGO is selected in order to estimate the rotor position and the speed from the measurement of the DFIG currents and voltages, and compared with fuzzy sliding mode observer. For testing the proposed control scheme performance, a 1.5 MW DFIG system is developed and simulated using MATLAB/Simulink. The obtained results demonstrate the effectiveness of the proposed control scheme in the presence of various DFIG parameters variation. Additionally, the control objective is achieved without speed sensor.",

      "abstract": "The objective of this study is to design and implement an observer for quarter-car active suspension system in Port-Hamiltonian form. A novel state observer is designed for active suspension system modelled in port-Hamiltonian form to estimate the states in presence of road disturbances. The observer is designed considering suspension deflection alone as the output, which is an easily measurable output. Performance of the proposed observer is evaluated experimentally with road disturbance input mimicking a sudden bump and a continuously varying road input, and proven to be effective in minimising the error dynamics in presence of bounded unmodelled disturbances. To prove the effectiveness of the state-estimator, an Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) designed using the desired physical properties of the closed-loop system is implemented using the observer states. Experimental results of the controller implemented using the designed state observer show good improvement in the ride comfort, ride stability and suspension stroke of the active suspension system, which proves the effectiveness of the proposed port-Hamiltonian observer in terms of minimising the error dynamics.",

      "abstract": "A robot system would inevitably cause unpredictable collisions in an unknown or unstructured environment. In this paper, the controllability conditions of a general robot system with compliant actuators are proposed to judge and assess the contact constraints based on Port-based Hamiltonian. In order to satisfy the proposed controllability conditions, one fuzzy coordinated control method inspired from the pathfinding of a blind or normal person in dark environment is proposed to deal with the problem of contact constraint. This method achieves velocity–torque combined control without using force or vision sensors compared with conventional methods. Finally, the experiments validate the feasibility of the controllability conditions to deal with contact constraint problems. The results show that the fuzzy coordinated controller can work more efficiently and effectively to detect and respond to contact constraints compared with the proposed proportional control.",

      "abstract": "This article introduces a unified Hamiltonian formulation for controlling grid-connected direct current microgrid via interconnection and damping assignment–passivity-based control. The direct current microgrid includes hydro–solar–wind hybrid renewable energy systems and battery/supercapacitor hybrid energy storage system. Hybrid renewable energy systems are integrated as a disturbed direct current source, while hybrid energy storage system is integrated via semi-active topology, where the battery is connected to the direct current bus through a bidirectional dc-to-dc converter. The proposed Hamiltonian approach allows us to design a control strategy for the bidirectional dc-to-dc converter and the grid-connected three-phase inverter to (1) reject power disturbances in the direct current bus via the supercapacitor and ensure smooth current in the battery as well as in the grid and (2) assign the system to a desired equilibrium after sharp changes. In the studied article, the stability of the system under the interconnection and damping assignment–passivity-based control controller is investigated. The interconnection and damping assignment–passivity-based control controller is compared with two conventional proportional–integral–based controllers through simulations under the MATLAB/Simulink environment. The main contributions in this article are the unified hybrid modelling for dc-to-dc power converter and grid-connected inverter using port-Hamiltonian approach, external disturbance rejection in the multi-source power system using interconnection and damping assignment–passivity-based control, and the assurance of global asymptotic stability of the closed-loop system.",

Nonlinear friction is modeled with a modified LuGre dynamic friction model. The internal states of the dynamic friction model are incorporated as generalized coordinates in a port-controlled Hamiltonian formulation for the complete mechanical system in such a way that all passivity properties of this formulation are preserved for the extended generalized coordinates system. Interconnection and damping assignment passivity-based control laws are developed for the models of two case studies: a building with a magneto-rheological damper and a double pendulum. Simulation results are also presented.",

It is well known that interconnection and damping assignment passivity-based control’s design methodology is based on the physical properties of the system where the kinetic and potential energy profiles are shaped, and asymptotic stability is achieved by damping injection. Based on the choice of control variables, special cases of the control law are derived, and tuning of the control law with the physical meaning of the variables is demonstrated along with their simulation results. The proposed control law is experimentally validated on a scaled model of a quarter-car active suspension system with different road profiles, varying load conditions, and noise and delay in the sensor measurements and actuator respectively. The results are compared with that of an uncontrolled system with linear quadratic regulator and sliding mode control.",

      "abstract": "With the ever-increasing permeation of wind energy into electrical grids, the low operating efficiency and poor stability seem to become major challenges for the power industry because of the stochastic characteristic of wind speeds. Aiming at these problems, this article designs a novel hybrid control method for a permanent magnet synchronous generator–based wind energy conversion system. A port-controlled Hamiltonian with dissipation model is proposed to apply in the models of the machine and grid-side converters of the permanent magnet synchronous generator–based wind energy conversion system. Then, this port-controlled Hamiltonian with dissipation model is used to the energy shaping method of interconnection and damping assignment. The hybrid control strategy, containing the outer-loop proportional–integral control and inner-loop passivity-based control, is finally designed in this article. To achieve the analysis, a Simulink model of the 1.5 MW permanent magnet synchronous generator–based wind energy conversion system is established under various types of wind speeds. A comparative analysis between the proposed hybrid control strategy and conventional proportional–integral vector control is conducted through the electrical behaviors and the harmonic distortion rates. The simulation results verify that the hybrid control strategy has better regulation performance than that of conventional proportional–integral control strategy in terms of maintaining at optimal state and improving system stability. It is also demonstrated that the proposed control strategy optimizes the quality of supplied power, which is of significance to reduce the harmonic pollution of wind energy.",

A unified expression is derived for systems of order 2                    m                    that generalizes known results for Timoshenko beams and Kirchhoff plates. This formula facilitates passivity verification and leads directly to optimal linear-quadratic boundary feedback laws in the form of viscous damping. The analysis is extended to non-collocated boundary control and establishes generalized passivity conditions. Numerical simulations validate the exponential stability achieved with the proposed control laws and illustrate the trade-offs between damping strength and control effort.",

      "abstract": "During operation, high-speed elevators experience significant longitudinal vibrations in their car systems due to variations in shaftway conditions and system parameter uncertainties, affecting ride comfort and safety. Existing active control methods often rely on absolute motion measurements, leading to high sensor costs and practical constraints. To address this issue, this study proposes an active control strategy based on Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC), using only relative displacement and velocity feedback. A seven-degree-of-freedom longitudinal vibration model of the nonlinear high-speed elevator car system is first established. Then, based on the Port-Hamiltonian (PH) principle and relative-state reconstruction, the PH form of the car system is constructed. Through energy shaping and damping injection, the IDA-PBC controller transforms the original nonlinear system into a linear system with ideal damping performance, and the final control law depends only on the relative displacement and velocity of the car system. Conditions for global asymptotic stability are derived, and parameter selection criteria are proposed to enhance robustness against model parameter uncertainties. Comparative simulations with passive, Skyhook, and PID control are conducted under random excitation and emergency braking, and parameter sweep simulations are performed by varying key mass, stiffness, and damping parameters within ± 20% of their nominal values. The results show that the proposed method reduces the typical longitudinal vibration acceleration by more than 60% in the considered simulation cases, while the vibration responses remain bounded under the tested parameter variations. This study provides a theoretical and numerical basis for further developing active longitudinal vibration control strategies for high-speed elevators.",

      "abstract": "In order to achieve high motion accuracy and better robustness of the rocket launcher position servo system driven by a permanent magnet synchronous motor, a passivity-based controller based on improved active disturbance rejection control is proposed in this article. The convenient method of interconnection and damping assignment and passivity-based control is adopted to establish the port-controlled Hamiltonian system with dissipation model of permanent magnet synchronous motor. To further enhance the robustness and adaptability of the traditional active disturbance rejection controller, an improved active disturbance rejection control strategy–based radical basis function neural network is introduced to on-line update the proportional and derivative gains of improved active disturbance rejection controller. The results of numerical simulation and bench test indicate that the proposed improved active disturbance rejection control passivity–based control algorithm has advantages of smaller overshoot, fast response, small steady-state error, and strong robustness. It proves that the proposed control scheme is effective and suitable.",

      "abstract": "This work considers the problem of decentralized control of inverter-based ac micro-grid in different operation modes. The main objectives are to (i) design decentralized frequency and voltage controllers, to gather with power sharing, without information exchange between microsources (ii) design passive dynamic controllers which ensure stability of the entire microgrid system (iii) capture nonlinear, interconnected and large-scale dynamic of the micro-grid system with meshed topology as a port-Hamiltonian formulation (iv) expand the property of shifted-energy function in the context of decentralized control of ac micro-grid (v) analysis of system stability in large signal point of view. More precisely, to deal with nonlinear, interconnected and large-scale structure of micro-grid systems, the port-Hamiltonian formulation is used to capture the dynamic of micro-grid components including microsource, distribution line and load dynamics as well as interconnection controllers. Furthermore, to deal with large signal stability problem of the microgrid system in the grid-connected and islanded conditions, the shifted-Hamiltonian energy function is served as a storage function to ensure incremental passivity and stability of the microgrid system. Moreover, it is shown that the aggregating of the microgrid dynamic and the decentralized controller dynamics satisfies the incremental passivity. Finally, the effectiveness of the proposed controllers is evaluated through simulation studies. The different scenarios including grid-connected and islanded modes as well as transition between both modes are simulated. The simulation conforms that the decentralized control dynamics are suited to achieve the desired objective of frequency synchronization, voltage control and power sharing in the grid-connected and islanded modes. The simulation results demonstrate the effectiveness of the proposed control strategy.",

A novel weighted balacend realization and model order reduction procedure is proposed which preserves port-Hamiltonian structure as well as stability, reachability and observability of the original system. This implies that one can utilize the intrinsic physical properties such as physical energy and the corresponding dissipativity for the reduced order model. Further, the proposed method reduces the computational effort in solving partial differential equations for nonlinear balanced realization.

      "abstract": "This paper gives a new passivity based control of active magnetic bearing systems. First we give a new modeling in port-Hamiltonian form of flywheel systems. Second, we give a new passivity based control which does not have any canceling term for the gyroscopic effect unlike the conventional cross-feedback control, and also does not have any gains to make the closed-loop unstable unlike PID feedback control. In this paper, the linear control is especially studied from the viewpoint of comparisons. Finally we give some simulation and experimental results and confirm the validity of the control methodology in the presence of unbalance influence.",

For underactuated systems, nonlinear partial differential equations (PDEs) must be solved to derive the IDA-PBC and it is a difficult task in general. However, this study shows that the MIP can be properly described as a full actuated port-Hamiltonian system focusing only on the pendulum dynamics. The controller is derived without solving the PDEs. Although our controller is for only the pendulum part of the system, the translational acceleration can be indirectly controlled utilizing the relation between the inclination of the pendulum and the acceleration arising from instability of the system. The controller can achieve various properties through energy shaping procedure of the IDA-PBC. Especially an energy function which will lead to safe operation of the MIP is proposed in this study. The function ensures that motion of the pendulum is restricted in a predefined region and converges to a desired pendulum angle. The controller also gets the pendulum back to the desired angle with a large state-dependent gain when the pendulum comes close to fall over. Effectiveness of the controller is verified through simulations.",

The controller shapes the total energy of the system and utilizes instability of the MIP for acceleration. The body angle and the displacement are controlled to keep statically unstable but dynamically stable states. The intentional destabilization leads to indirect control of translational acceleration. The total energy of the system is shaped such that the energy becomes minimum at given desired states, and the system is controlled to converge to them. To derive the energy shaping controller, the system has to be described as a port-Hamiltonian (PH) system. In this study the MIP is shown to be appropriately described as a PH system and the controller is obtained. It can achieve various control properties through the energy shaping procedure. Especially an energy function that will lead to safe operation of the MIP is proposed. The function ensures that motion of the MIP is restricted within predefined regions, and converges to the desired states. The controller also returns the system back to the desired states with state-dependent gains that become large if the MIP comes close to fall over. Effectiveness of the proposed controller and utilization of instability for the MIP with a center of gravity moving mechanism are verified through simulations.",

These condensed forms allow for the further analysis of the properties of port-Hamiltonian DAEs and to study, e.g., existence and uniqueness of solutions or to determine the index.

      "abstract": "Delay-based reservoir computing with temporally multiplexed virtual nodes provides a hardware-efficient platform for photonic implementations, yet parameter selection is often guided by empirical tuning. Here, we report a systematic experimental study of a single-node delay-based photonic reservoir computer that resolves the key physical and dynamical factors governing computational performance using the nonlinear channel equalization (NCE) benchmark. By mapping the bifurcation landscape of the system using port-Hamiltonian formulation, we establish a direct correspondence between operating regime and NCE performance as well as memory capacity, showing that optimal performance occurs near, but below, the onset of oscillatory and chaotic dynamics. We further provide a unified comparison of temporal optimization strategies, including delay–input period desynchronization and controlled local node coupling, within the same physical platform. At a 19 dB signal-to-noise ratio, the symbol error rate (SER) decreases with increasing node count before saturating beyond                    N                     ≈ 50, indicating task-dependent performance saturation and practical scaling constraints in delay-based reservoir architectures. A readout shifting strategy further improves the performance, achieving an SER of 0.003. These results provide physics-informed insights into parameter selection and architectural optimization in delay-based photonic reservoir computing for scalable, high-speed operation.",

      "abstract": "The finite-time stabilization and finite-timeH∞control problems of Port-controlled Hamiltonian (PCH) systems with disturbances and input saturation (IS) are studied in this paper. First, by designing an appropriate output feedback, a strictly dissipative PCH system is obtained and finite-time stabilization result for nominal system is given. Second, with the help of the Hamilton function method and truncation inequality technique, a novel output feedback controller is developed to make the PCH system finite-time stable when IS occurs. Further, a finite-timeH∞controller is designed to attenuate disturbances for PCH systems with IS, and sufficient conditions are presented. Finally, a numerical example and a circuit example are given to reveal the feasibility of the obtained theoretical results.",

      "abstract": "Understanding pedestrian crowds as complex systems reveals how simple individual interactions yield rich collective behaviors. In this study, we adopt an energy-based modeling framework – port-Hamiltonian (pH) systems – to analyze a minimalist variant of the social-force model with stochastic elements. This perspective interprets the dynamics as an extended Hamiltonian system that incorporates energy dissipation, control inputs, and outputs. Within this formulation, the Hamiltonian, the supplied power and the direction-alignment variable emerge as meaningful macroscopic orderparameters that characterize long-term behavior of the system. This enables us to identify self-organized strip formation by distinguishing ordered from disordered states, and to highlight the interplay between dissipation and diffusion. Moreover, for specific parameter settings, we observe noise-induced ordering. These preliminary findings open promising avenues for deeper theoretical investigation.",

      "abstract": "Context: This study focuses on advanced control techniques for permanent magnet synchronous machines (PMSMs), which are crucial in various industrial applications due to their efficiency and precise control requirements. Passivity-based control methods offer stability and performance, addressing these challenges effectively. Method: A passivity-based model predictive control (MPC) is proposed, integrating port-Hamiltonian representation with optimization. Stability theorems are theoretically explored. The simulation evaluates the performance of our proposal under different prediction horizons and stability constraints. Results: The proposed MPC is analyzed across several horizons, both including and excluding passivity and exponential stability constraints.  Conclusions: This study presents a novel passivity-based MPC approach for PMSM speed regulation, highlighting the importance of stability constraints. Future research should extend this controller to synchronous machines in power systems and voltage source converters.",

The analysis employs one-dimensional partial differential equations, including integro-differential terms, to evaluate exponential stability via a Port-Hamiltonian control mechanism. The proposed approach demonstrates how a simplified structural framework, used to estimate the carbon dehydration process within a dynamic model, enables seamless integration of carbon transfer control strategies across domains. Numerical examples are included to illustrate the model’s effectiveness and real-world applicability.",

Corresponding pseudo-port Hamiltonian system is proposed. Moreover, it is proved that bioheat transfer equation forms a contraction and dissipative system. Mild solution for bioheat transfer equation and its adjoint problem are proposed. Controllability and exponentially stability for the related system is proved.

By using Hamiltonian energy function and Casimir function comprehensively, the design method is proposed to overcome the difficulties taken by link dynamics. The Hamiltonian function is used to handle the dynamic of agent, while the Casimir function is constructed to deal with the dynamic of link. Thus the Lyapunov function is generated by modifying the Hamiltonian function of forced Hamiltonian systems. Then, the proposed approach is applied in multi-machine power systems, which are interconnected in microgrid with power frequencies as link dynamics. Finally, the simulation result demonstrates the effectiveness of the gotten method.",

This paper deals with a speed observer for a visual servoing system based on the immersion and invariance (I&I) technique. The visual servoing system, a new binocular stereo visual model (BSVM) is considered, which 3-dimension image information is obtained directly, that we need not to estimate the depth information. We have considered the visual servoing system that contained the non-linear robot dynamics, an image-based controller and a speed observer. It will make the stabilisation analysis of the closed-loop system very difficult. A controller is designed so that the robot visual servoing system is transformed into a port-controlled Hamiltonian (PCH) system. It will simplify the stabilisation analysis. For the PCH system, firstly, a speed observer is designed by the technical of I&I. Secondly, a visual servo controller is designed to satisfy the visual servoing performance. Simulation experiments illustrate the theory and show the effectiveness of the proposed designs.",

Das vorgeschlagene Diskretisierungsverfahren erhält nicht nur die Port-Hamiltonsche Struktur, sondern auch wichtige Erhaltungseigenschaften des zugrundeliegenden infinit-dimensionalen Systems. Als Anwendungen werden eine Übertragungsleitung und ein randgespeistes Maxwellsches System betrachtet. Numerische Experimente zeigen, dass die Finite-Elemente-Methode durch Verwendung von Formfunktionen höherer Ordnung höhere Konvergenzraten als bestehende Ansätze zur strukturerhaltenden Diskretisierung Port-Hamiltonscher Systeme erzielt. Bei vorgegebener Fehlertoleranz führt das vorgeschlagene Verfahren daher zu einer beträchtlichen Reduktion der Dimension des finit-dimensionalen Modells.",

Based on integral balance equations and topological information, this representation is exact and qualifies as a control model. The finite-dimensional approximation requires an energy discretization that yields discrete constitutive equations. We give (i) a brief overview of discrete modeling of conservation laws on <jats:italic>n</jats:italic>-complexes and (ii) extend existing results by allowing for mixed physical types of boundary inputs. This requires the construction of a primal and a dual complex based on the underlying staggered grids and the localization of the inputs on the system boundary. Finally, (iii) we discuss the properties of the resulting structure-preserving discretization scheme based on a consistency analysis for the 2D nonlinear shallow water equations.",

Weiterhin werden die Struktur und Approximationsgüte der resultierenden endlich-dimensionalen Zustandsraummodelle in Abhängigkeit der Entwurfsfreiheitsgrade analysiert. Hierzu werden exemplarisch die eindimensionale lineare Wellen- und Wärmeleitungsgleichung betrachtet und zunächst Eigenwertlagen und Lösungen von Anfangswertaufgaben analysiert. Im Hinblick auf den Steuerungsentwurf wird die Erhaltung eines flachen Ausgangs für die Wärmeleitungsgleichung nachgewiesen und die Güte der angenäherten Randsteuerungen untersucht.",

The model structure is exploited for inversion-based feedforward control, and the control loop is closed via an observer for the friction torque and the state difference. Experimental results for the reference input and the disturbance response illustrate the quality of the design.",

      "abstract": "This contribution is concerned with the design of observers for a single mast stacker crane, which is used, e. g., for storage and removal of loads in automated warehouses. As the mast of such stacker cranes is typically a lightweight construction, the system under consideration is described by ordinary as well as partial differential equations, i. e., the system exhibits a mixed finite-/infinite-dimensional character. We will present two different observer designs, an Extended Kalman Filter based on a finite-dimensional system approximation, using the Rayleigh-Ritz method and an approach exploiting the port-Hamiltonian system representation for the mixed finite-/infinite-dimensional scenario where in particular the observer-error system should be formulated in the port-Hamiltonian framework. The mixed-dimensional observer and the Kalman Filter are employed to estimate the deflection of the beam based on signals acquired by an inertial measurement unit at the beam tip. Such an approach considerably simplifies mechatronic integration as it renders strain-gauges at the base of the mast obsolete. Finally, measurement results demonstrate the capability of these approaches for monitoring and vibration-rejection purposes.",

The model class of pH-DAEs enables energy-based modeling and a flexible coupling of models across different physical domains. This makes them particularly suited for the simulation and control of complex technical systems. To promote the use of recent theoretical findings in engineering practice, efficient software solutions are required. In this work, we illustrate how possibly large-scale pH-DAEs can be efficiently stored and interconnected in MATLAB in an object-oriented way. We discuss three structure-preserving MOR strategies that are supported by MORpH and demonstrate the application and performance of selected MOR algorithms by means of two benchmark examples.",

      "abstract": "Adaptive structures are equipped with sensors and actuators to actively counteract external loads such as wind. This can significantly reduce resource consumption and emissions during the life cycle compared to conventional structures. A common approach for active damping is to derive a port-Hamiltonian model and to employ linear-quadratic control. However, the quadratic control penalization lacks physical interpretation and merely serves as a regularization term. Rather, we propose a controller, which achieves the goal of vibration damping while acting energy-optimal. Leveraging the port-Hamiltonian structure, we show that the optimal control is uniquely determined, even on singular arcs. Further, we prove a stable long-time behavior of optimal trajectories by means of a turnpike property. Last, the proposed controller’s efficiency is evaluated in a numerical study.",

      "abstract": "A general framework for the numerical approximation of evolution problems is presented that allows to preserve an underlying dissipative Hamiltonian or gradient structure exactly. The approach relies on rewriting the evolution problem in a particular form that complies with the underlying geometric structure. The Galerkin approximation of a corresponding variational formulation in space then automatically preserves this structure which allows to deduce important properties for appropriate discretization schemes including projection based model order reduction. We further show that the underlying structure is preserved also under time discretization by a Petrov–Galerkin approach. The presented framework is rather general and allows the numerical approximation of a wide range of applications, including nonlinear partial differential equations and port-Hamiltonian systems. Some examples will be discussed for illustration of our theoretical results, and connections to other discretization approaches will be highlighted.",

      "abstract": "In this research article, a control approach for port-Hamiltonian PH systems based in a neural network (NN) quaternion-based control strategy is presented. First, the dynamics is converted by the implementation of a Poisson bracket in order to facilitate the mathematical model in order to obtain a feasible formulation for the controller design based on quaternion NNs. In this study, two controllers for this kind of of system are presented: the first one consists in the controller design for a PH system about its equilibrium points taking into consideration the position and momentum. This mean is achieved by dividing the quaternion neural controller into scalar and vectorial parts to facilitate the controller derivation by selecting a Lyapunov functional. The second control strategy consists in designing the trajectory tracking controller, in which a reference moment is considered in order to drive this variable to the final desired position according to a reference variable; again, a Lyapunov functional is implemented to obtain the desired control law. It is important to mention that both controllers take into advantage that the energy consideration and that the representation of many physical systems could be implemented in quaternions. Besides the angular velocity, trajectory tracking of a three-phase induction motor is presented as a third numerical experiment. Two numerical experiments are presented to validate the theoretical results evinced in this study. Finally, a discussion and conclusion section is provided.",

      "abstract": "Dieser zweite Teil des Beitrages setzt mit den Kapiteln 5 bis 9 den im letzten Heft erschienenen ersten Teil fort. Dabei wird im Kapitel 5 eine Art kanonische Form passiver Systeme, die es sehr schön erlaubt, die Energieflüsse im Systeminneren und mit der Systemumgebung zu charakterisieren, vorgestellt. Diese Klasse nichtlinearer Systeme, auch unter dem Namen PCHD-Systeme (port-controlled Hamiltonian systems with dissipation) bekannt, bildet den Ausgangspunkt für den im Kapitel 6 beschriebenen passivitätsbasierten Reglerentwurf und die Methode des Einbringens von zusätzlicher Dämpfung in den geschlossenen Kreis. Die Dissipativität und die Passivität sind zufolge ihrer Definition mit dem Zustand des Systems verbunden. Im Gegensatz dazu ist der im Kapitel 7 eingeführte Begriff der positiven Reellheit eine Eigenschaft des Eingangs-Ausgangsverhaltens und damit vom Zustand unabhängig. Die Verbindung der positiven Reellheit mit der L 2-Stabilität und der Passivität sowie eine detaillierte Herleitung des aus der linearen Theorie wohlbekannten Kalman-Yakubovich-Popov-Lemmas, formuliert für nichtlineare Systeme mit affinem Eingang, werden ausführlich im siebten Kapitel besprochen. Das Kapitel 8 ist dem klassischen Konzept der absoluten Stabilität gewidmet. Es wird gezeigt, dass sich die Kriterien zur Überprüfung der absoluten Stabilität, hier im Speziellen das Kreiskriterium und das Popov-Kriterium, auf ein allgemeineres Kriterium, welches auf der Rückkopplung zweier passiver Systeme beruht, zurückführen lassen. Diese Vorgangsweise führt zwar auf die aus der Literatur bekannten Ergebnisse, gibt aber einerseits einen tieferen Einblick in die Idee, die hinter diesen Konzepten steckt, und ermöglicht andererseits die Entwicklung vollkommen neuer Kriterien. Im neunten und letzten Kapitel werden die Ergebnisse dieses Beitrages kurz zusammengefasst.",

Die Struktur der geregelten Strecke als Port-Hamilton (PH) System ist physikalisch motiviert und beruht auf der Speicherung, dem Austausch und der Dissipation von Energie. Die Wirkung der Entwurfsparameter in den vorzugebenden Struktur- und Dämpfungsmatrizen sowie der Energiefunktion auf das Zeitverhalten ist jedoch in der Regel undurchsichtig. Die Betrachtung der Linearisierung des geregelten nichtlinearen Systems in Abhängigkeit der Entwurfsparameter bietet die Möglichkeit, wenigstens lokal gewünschtes Zeitverhalten systematisch im Regelungsentwurf zu berücksichtigen.",

      "abstract": "The desire for energy independence presupposes the use of various types of elements for energy generation from renewable sources, for the stand-alone operation of which energy storage devices are required. Apower generation complex created in this way must perform a number of tasks that are formed by the energy management system. The control system performs these tasks and ensures proper static and dynamic characteristics of this complex with many inputs and outputs. The results of recent world researches, as well as the authors experience of this work, show that,for creating such control systems, it is advisable to use Passive-Based Control (PBC), presenting the control object as a Port-Controlled Hamiltonian (PCH) system. Thanks to the developed method of additional interconnections and damping injection (Interconnection &amp; Damping Assignment -IDA) passive control provides ample opportunities to adjust the control effects, while ensuring the asymptotic stability of the system as a whole. This is particularly useful in the complex system considered in this paper that includes both a hybrid power plant for electricity generation from the sun and windanda hybrid energystorage unit consisting of the battery and supercapacitor module. This article shows the procedure of PBCsystem synthesis, according to which three structures of control influence formers (CIF) were designed and investigated. These structures have different combinations of additional interconnections and damping, which allows forming the desired energy flows inside the closed-loop systemand therefore provide desired control results.Among them, there are tasks of maintaining voltages on the DC bus and the supercapacitor module at referencelevels, and the smoothness of the battery current transients.A comparative simulation studies were performed on a computer model of the power generation complex with synthesized control systems, whichwas created in the MATLAB/Simulink environment. It showed the efficiency of their work and the advantages of different CIF structures.",

      "abstract": "Energy storage systems are a topical modern area of research due to the rapid development of renewable energy and electric vehicle construction. Due to the current lack of a source or accumulator of electricity with high specific energy and power, it is being replaced by hybrid electricity storage systems, which consist of separate, complementary sources. Among them, the combination of electrochemical battery – supercapacitor bank is the most common. The paper considers its active configuration, in which both sources are connected to the output network through bidirectional pulse DC-DC converters. The studied hybrid battery-supercapacitor system is a nonlinear dynamic system with multiple inputs, multiple outputs, and two control channels, the operation of which is described by five differential equations. To solve the problem of synthesis of a stable and efficient control system for such an object, the energy approach, namely energy-shaping control has been used. To do this, the studied system is mathematically described as Port-Controlled Hamiltonian system, and two descriptions are compared with different options for choosing the basic vector of the system state. The structural synthesis of the passive control system was performed by the Interconnection and Damping Assignment method. Based on the energy management strategy developed for the system under study, all possible options for introducing interconnections and damping into the passive control system were explored using a computer program developed in the MathCad environment. The effectiveness of the obtained structures of control influence formers on the investigated dynamic system was studied by computer simulation in the Matlab/Simulink environment. According to the results of the research, the variant of control influence former with the best combination of introduced interconnections and damping is formed according to the principle of superposition. To stabilize the voltage values of the output network and the supercapacitor unit set by the control strategy, a proportional-integrated voltage regulator is additionally used, and a sliding regulator between two passive control structures is exploited to limit the allowable battery current. The results of the computer simulation showed the full implementation of the tasks ofthe energy management strategy, including a smooth increase and limitation of the battery current.",

      "abstract": "Currently, light electric vehicles are rapidly developing in various kinds. To power these vehicles with batteries, the simplest electric drive system is a DC motor controlled by a DC-DC converter. This work utilizes a bidirectional Zeta-SEPIC DC-DC converter with an integrated DC motor. This implementation enables control of motor speed and torque in traction and regenerative braking modes. Additionally, it allows for the use of a lower voltage battery compared to the motor's rated voltage, reducing battery weight and increasing safety. In this work, a decomposition approach is applied. Two separate port-controlled Hamiltonian subsystems are obtained to adjust the motor angular velocity in the traction (Zeta) and braking (SEPIC) modes of the DC-DC converter. The Passivity-Based Control (PBC) method is used to synthesize the drive control subsystems in these modes. This method is based on the energy laws of processes in systems and provides asymptotic stability of nonlinear systems, in this case, two fourth-order subsystems for speed control. Two third-order current control subsystems synthesized by the PBC were used to limit the motor current at a given level. The synthesis resulted in sets of possible structures of control influence formers (CIFs) for all PBC subsystems using Zeta and SEPIC DC-DC converters. The study analyzed the operation of the obtained structures of the CIFs, selected the most effective ones, and determined the laws of adaptation of their parameters to the value of the motor angular velocity through computer simulation in Matlab/Simulink. The results of the simulation showed that the drive operated well in both static and dynamic modes.",

Three types of time delays, including state delay, input delay, and output delay, are all assumed to be bounded. By introducing the output feedback control law and utilizing serval Lyapunov–Krasovskii functionals, we present three delay-dependent stability criteria in terms of the linear matrix inequality. Meanwhile, we use Wirtinger’s inequality, constraint conditions, and Lyapunov–Krasovskii functionals of triple and quadruple integral form to obtain less conservative results.

First, starting with discrete-time port-controlled Hamiltonian systems, a novel controller is presented to achieve practical FT stability of the obtained closed-loop system. Moreover, in order to well handle the abrupt changes at switch moments in practical switched systems, another novel controller is presented in terms of positive-order Lyapunov functions approach and range dwell time method to make discrete-time impulsive switched port-controlled Hamiltonian system practical FT stable. Ultimately, the validity of proposed methods is illustrated by simulations.",

While for general unstructured DAEs the characterization of these distances is very difficult and partially open, it has been shown in [C. Mehl, V. Mehrmann, and M. Wojtylak, Distance problems for dissipative Hamiltonian systems and related matrix polynomials, Linear Algebra Appl., 623 (2021), pp. 335–366] that for dissipative Hamiltonian systems and related matrix pencils there exist explicit characterizations. We will use these characterizations for the development of computational methods to approximate these distances via methods that follow the flow of a differential equation converging to the smallest perturbation that destroys the property of regularity, index one, or stability.",

By explicitly considering the energy and power in a robotic system, many control and design problems become easier or more insightful than in a purely signal-based view. We show the application of these energy considerations to robotics; starting from the fundamental aspects, but, most importantly, continuing to the practical application to robotic systems. Using the theory of Port-Hamiltonian Systems as a fundamental basis, we show examples concerning energy measurement, passivity and safety. Control by interconnection covers the shaping and directing of energy inside the controller algorithms, to achieve desired behaviour in a power-consistent manner. This idea of control over the energy ﬂows is extended to the physical domain. In their mathematical description and analysis, the boundary between controller and robot disappears and everything is an interconnected system, driven by energy exchange between its parts.",

More precisely, a passivity based approach for the stabilization of temperature profile inside a well-insulated bar with heat conduction in a one-dimensional described by parabolic partial differential equations (PDEs) is developed. This approach is motivated by an appropriate model reduction schema using the finite difference approximation method. On this basis, it allows to discretize and then, write the original parabolic PDEs into a Port Hamiltonian (PH) representation. From this, the boundary control input is therefore synthesized using passive tools to stabilize the temperature at a desired reference profile asymptotically. The infinite dimensional nature of the original distributed parameter system in the PH framework is also discussed. Numerical simulations illustrate the application of the developments.",

Physical parameters are remodeled as random variables to conduct an uncertainty quantification. A stochastic Galerkin projection yields a larger deterministic system of ODEs, which does not exhibit a pH form in general. We apply transformations of the original systems such that the stochastic Galerkin projection becomes structure-preserving. Furthermore, we investigate meaning and properties of the Hamiltonian function belonging to the stochastic Galerkin system. A large number of random variables implies a high-dimensional stochastic Galerkin system, which suggests itself to apply model order reduction (MOR) generating a low-dimensional system of ODEs. We discuss structure preservation in projection-based MOR, where the smaller systems of ODEs feature pH form again. Results of numerical computations are presented using two test examples. </p>",

      "abstract": "A DC hybrid power source composed of photovoltaic cells as the main power source, Li-ion battery storage as the secondary power source, and power electronic interface, is modeled based on port-controlled Hamiltonian systems and Euler-Lagrange framework. Subsequently, passivity-based controllers are synthesized. Local asymptotic stability is ensured as well. In addition, a power management system is designed to manage power flow between components. Modeling and simulation of the proposed hybrid power source is accomplished using MATLAB/Simulink. Our interest is focused on the comparison of the two passivity-based control methods and their use in hybrid power systems.",

These arise from interactions with a viscous medium, a priori uncertainty, and variability in the system’s dynamic parameters, as well as the complexity and computational cost of first-principles models and the challenges of identification procedures. This paper proposes the use of neural network parameterization of ordinary differential equations based on the port-Hamiltonian formalism to develop accurate and computationally efficient dynamic models of underwater robots. These models can be used for trajectory prediction, integration with onboard sensor data for localization systems, and controller synthesis. The proposed approach captures both the physical structure of the system and the impact of uncertainties, enabling the creation of physically grounded, data-driven representations of complex nonlinear dynamics. Comparative experiments with classical identification and modeling methods using real-world data from an underwater robot demonstrate advantages of the proposed method in prediction accuracy and its robustness over long-horizon prediction.",

      "abstract": "This study explores an application of robust nonlinear control to an underactuated inverted pendulum system (UIPS), a type of underactuated mechanical system, by first transforming the perturbed system into a form of a port-controlled Hamiltonian system (PCH), then utilizing the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) methodology to achieve the stabilization of an unperturbed closed-loop PCH system with an assigned energy function that qualifies as a Lyapunov candidate at the unstable equilibrium point. From there, the problem of robustification of IDA-PBC for a perturbed closed-loop PCH system with the state-dependent input matrix of the UIPS, subject to constant matched disturbances, is addressed by adding an outer-loop controller with an additional state. This results in a new system that preserves the framework of a PCH system, rejects the disturbance, and has a new energy function that again serves as a Lyapunov function at the desired equilibrium point. This proposed methodology is called integral IDA-PBC (iIDA-PBC). The effectiveness and applicability of the proposed method are thoroughly assessed through numerical simulations and experimental validation on the UIPS. The results demonstrate the method's proficiency in handling the system’s constant matched disturbances and model inaccuracies, underscoring the potential of iIDA-PBC for broader applications in systems facing similar control challenges.",

      "abstract": "This work proposes an Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) to enhance power quality of an islanded Micro-grid (MG) including a photovoltaic main source (PV) and a Li-ion battery based Energy Storage System (ESS). In this MG, the PV generator-unit is controlled to provide its maximum power and the ESS-unit is controlled to ensure the desired voltage waveform at the Point of Common Coupling (PCC) and to support the PV source in order to satisfy the local loads. The IDA-PBC approach is chosen for its proprieties which allow the synthesis of asymptotically stable controllers for passive systems by the mean of the power system energy. In fact, the damping and interconnection coupling matrices of the IDA-PBC controller allows additional degree of freedoms in comparison to classical passivity controllers that enhance the convergence rapidity and the robustness under uncertainties. The mathematical model of the PV source and the Li-ion battery based ESS are presented. The power interface circuits are firstly represented through Park-coordinates then expressed in a Port-Controlled Hamiltonian (PCH) form. The obtained models are used to the design of the proposed IDA-PBC controller where the stability conditions are checked. The proposed control validity and performance are verified through comparison simulation tests with a conventional Proportional-Integral (PI) based control strategy. The obtained results show that the proposed control algorithm allows reducing the current and voltage overshoots under transient’s conditions in comparison to the PI controller. Furthermore, the proposed control achieves better voltage waveform at the PCC in steady state.",

The control law design uses the passivity approach. Novelty. The novelty consists in designing a control law for a photovoltaic system using a passivity approach based on energy shaping and associated with damping injection. Purpose. The purpose consists to develop a tool for design and optimize a control law of the photovoltaic system in order to improve its efficiency under some conditions such as the variations of the temperature, the irradiation and the parameters. Also, the control law design should be simple with a lower overshoot and a shorter settling time. Methods. This work uses the port Hamiltonian mathematical approach with minimization of the energy dissipation in boost converter of the photovoltaic system to illustrate the modification of energy and generate a specify duty cycle applied to the converter. Results. The results with MATLAB/SimPowerToolbox® have proven the robustness against parameter variations and effectiveness of the proposed control. Practical value. The experimental results, carried out using a dSPACE DS1104 system, are presented to show the feasibility and the robustness of the proposed control strategy against parameter variations.",

      "abstract": "We present a learned structure-preserving surrogate operator in the form of a Hamiltonian Network that reproduces full-physics three-phase slightly-compressible flow simulations at roughly 10× lower computational cost while retaining fundamental conservation laws. We express the reservoir dynamics as a finite-volume port–Hamiltonian (pH) dynamic system and to progressively learn the Hamiltonian through its dynamic vector field with Bayesian optimization, and using a scalable mixture-of-Gaussian-process (MoGP) prior. The pH scaffold enforces mass balance, passivity, and Lyapunov stability by construction; the Bayesian GP treatment supplies calibrated epistemic uncertainty that propagates through the surrogate estimation state process and can be used to quantify forecast uncertainty in closed-loop reservoir management. Unlike previously published neural-operator and reduced-order surrogates, our method guarantees conservation without ad-hoc penalties and delivers analytic gradients for adjoint-free history matching.",

      "abstract": "A quaternion representation is often used to describe the attitude of a spacecraft because it does not have any singular points. However, it becomes difficult to control the attitude described by a quaternion since a quaternion has four parameters despite that the attitude has only three degrees of freedom. In this paper, we employ the concept of port-Hamiltonian modeling to control systems with quaternions to introduce a general nonlinear control system synthesis method in aerospace engineering. It is also shown that the error quaternions are also naturally described by the port-Hamiltonian framework. Furthermore, the additional design parameter achieved by the proposed method is utilized for obstacle avoidance control. A numerical example exhibits the effectiveness of the proposed method.",

      "abstract": "In this paper, we propose an energy-based nonlinear control for two-link flexible manipulators. Since the two-link flexible manipulator is an underactuated system which provides a challenge to control engineers and researchers. In order to control this kind of system more effectively, many new control theories and methods are explored to design controllers for the flexible manipulators. Among these methods, the energy-based control design method has gained a lot of attentions in these years, which can provide more physical insights in nonlinear control and also can provide a candidate for Lyapunov function directly, which is very important in proving the stability of the closed-loop system. Especially, the port-controlled Hamiltonian system and generalized canonical transformation have some advantages on the modeling and control design of these nonlinear systems. Therefore, we explore to control two-link flexible manipulators via generalized canonical transformation. Both the simulation and experimental results are shown to demonstrate the effectiveness of the controllers.",

      "abstract": "We consider the problem of (asymptotic) stabilization of mechanical systems with underactuation degree one. A state-feedback design is derived applying the interconnection and damping assignment passivity-based control methodology. Its application relies on the possibility of solving a set of partial differential equations that identify the energy functions that can be assigned to the closed-loop. The following results are established: 1) identification - in terms of some algebraic inequalities - of a subclass of these systems for which the partial differential equations are trivially solved; 2) characterization of all systems which are feedback-equivalent to this subclass; and 3) introduction of a suitable parametrization of the assignable energy functions that provides the designer with a handle to address transient performance and robustness issues. An additional feature of our developments is that the open-loop system need not be described by a port-controlled Hamiltonian (or Lagrangian) model, a situation that arises often in applications due to model reductions or preliminary feedbacks that destroy the structure. The new result is applied to obtain an (almost) globally stabilizing controller for the inertia wheel pendulum, a controller for the chariot with pendulum system that can swing-up the pendulum from any position in the upper half plane and stop the chariot at any desired location, and an (almost) globally stabilizing scheme for the vertical takeoff and landing aircraft with strong input coupling. In all cases we obtain very simple and intuitive solutions that do not rely on, rather unnatural and technique-driven, linearization or decoupling procedures but instead endows the closed-loop system with a Hamiltonian structure with desired potential and kinetic energy functions.",

The extended structure does not only use exterior derivative operators but Hodge star operators and their composite operators to relate flows with efforts. The structure represents a differential relation between energy variables and it shows clearly some geometric properties.",

      "abstract": "This paper deals with the energy based control of infinite-dimensional port-Hamiltonian systems, by exploiting structural invariants—so-called Casimir functionals—of the closed loop system. We confine ourselves to port-Hamiltonian systems, modeled within a jet-space approach, with one dimensional spatial domain and 2nd-order Hamiltonian. Therefore, the concept of structural invariants is extended from systems with 1st-order Hamiltonian to systems with 2nd-order Hamiltonian. To demonstrate the capability of this closed loop control methodology, a boundary controlled Euler-Bernoulli beam is used. Finally, simulation results conclude the paper.",

This scheme is based on the use of staggered grids for the discretization of the state and co state variables of the system. It is shown that, by an appropriate choice of the boundary port variables, the underlying geometric structure of the infinite-dimensional system, i.e. its Dirac structure, is preserved during the discretization step. The consistency of the spatial discretization scheme is evaluated and its accuracy is validated with numerical results.",

      "abstract": "For continuous-time port-Hamiltonian systems (PHS), safety can be shown using the Hamiltonian function as a barrier between the safe and unsafe states. However, the safety property may not be preserved when the system is discretized. This paper presents a safety analysis approach for discrete-time models of PHS using conservative time-discretization and applies the approach to the design of a safe integrated adaptive cruise control (ACC) and lane keeping control (LKC) system. Instead of performing safety analysis in continuous-time and then imposing conditions so that safety is preserved after discretization, safety conditions are developed for a discrete-time model. The approach is applied to the safety analysis of a vehicle dynamics composed with an ACC and a LKC. A hardware-in-the-loop simulation platform is used to evaluate the approach.",

In the dynamic control case, energy shaping is achieved by combining the physical energy of the plant and the emulated energy of the controller.",

Firstly, a structure preserving and passive LQG control design equivalent to Control by Interconnection is proposed. Based on this LQG controller, a structure preserving reduction method is used to approximate both the closed loop IDPHS and the LQG controller. This closed loop reduction guarantees that the reduced order controller will ensure acceptable closed loop performances on the infinite dimensional system. The proposed methods is applied to the control of a vibro-acoustic system.",

Energy-based modeling of each of these subsystems can yield a port-Hamiltonian (pH) representation. In this paper, a single-phase flow model, a dissipative mathematical component and a two-phase flow model are interconnected to model hydraulics for Managed Pressure Drilling (MPD) applications. These subsystems are interconnected in a power-preserving manner to build an aggregated pH system for real-life MPD scenarios. We prove that the interconnection junction connecting the single- and two-phase flow models is conditionally power-preserving.",

We use the port-Hamiltonian formalism as a high level model structure that is continuously refined based on our understanding of the physical process. In addition, we use machine learning inspired models as low level representations. Representation structure is key in learning generalizable models, as shown by the learning results.",

We consider a network of interconnected port-Hamiltonian systems that describes the powertrain components and auxiliaries in the vehicle. This description is suitable to obtain a systematic approach to formulate a decomposable optimal control problem for Complete Vehicle Energy Management. A physically insightful cost function that describes the total energy consumption of the vehicle is proposed in terms of internal energy and losses of each system connected to the network. Taking advantage of the modularity of the proposed formulation, we present a distributed optimization algorithm to find solutions to the energy management problem. To illustrate this modelling methodology, we consider a case study in which the energy consumption of a battery electric vehicle is optimized.",

      "abstract": "Task-invariant control methods for powered exoskeletons provide flexibility in assisting humans across multiple activities and environments. Energy shaping control serves this purpose by altering the human body's dynamic characteristics in closed loop. Our previous work on potential energy shaping alters the gravitational vector to reduce the user's perceived gravity, but this method cannot provide velocity-dependent assistance. The interconnection and damping assignment passivity-based control (IDA-PBC) method provides more freedom to shape a dynamical system's energy through the interconnection structure of a port-controlled Hamiltonian system model. This paper derives a novel energetic control strategy based on IDA-PBC for a backdrivable knee-ankle exoskeleton. The control law provides torques that depend on various basis functions related to gravitational and gyroscopic terms. We optimize a set of constant weighting parameters for these basis functions to obtain a control law that produces ablebodied joint torques during walking on multiple ground slopes. We perform experiments with an able-bodied human subject wearing a knee-ankle exoskeleton to demonstrate reduced activation in certain lower-limb muscles.",

The flexible beam's colliding equations exhibit instant changes during impact times, therefore the model is cast in the class of switched infinite dimensional operator systems. The aim is to study the stability of the closed loop system with a PD control law, making use of the semigroup formalism together with the Lyapunov stability theory. To this end, we present a new stability result making use of multiple Lyapunov functions obtained as an adaptation of a theorem from finite dimensional hybrid systems theory. We show the port-Hamiltonian modelling procedure for a controlled rotating flexible beam in impact scenario, using distributed parameter equations to describe the beam's dynamic. Then, we compute the equilibrium position of the closed loop system and using the shifted variables with respect to the equilibrium position, we cast the system in the class of switched infinite dimensional operator systems. Finally we select the Lyapunov functions for the contact and non-contact phases and we show, through numerical simulations, that they respect the assumptions of the proposed stability theorem.",

      "abstract": "It is shown that the state/costate dynamics arising in a certain class of linear quadratic differential games can be interpreted as the interconnection of (cyclo-passive) Port-Controlled Hamiltonian systems. This property relies on the fact that the (virtual) energy functions associated to each player depend only on the interplay between the inputs of the players, as opposed to the system's matrix or the individual cost functionals. Finally, it is shown that an arbitrarily accurate approximation of an open-loop Nash equilibrium strategy, obtained from the trajectories of the state/costate system, can be robustified by externally stabilizing the stable eigenspace of the underlying state/costate system.",

This formulation allows to cope with the second principle of Thermodynamics and exhibits the physical properties of the system. We extend the Interconnection and Damping Assignment-Passivity Based Control (IDA-PBC) method developed for port Hamiltonian systems to the available energy-based boundary control of IPHS. This method allows to achieve the desired equilibrium profile without constraints on the boundary conditions or on the initial profile of the plant. The method is illustrated by means of simulations considering the boundary control of the 1D heat diffusion in a copper rod.",

      "abstract": "Task-dependent controllers widely used in exoskeletons track predefined trajectories, which overly constrain the volitional motion of individuals with remnant voluntary mobility. Energy shaping, on the other hand, provides task-invariant assistance by altering the human body’s dynamic characteristics in the closed loop. While human-exoskeleton systems are often modeled using Euler-Lagrange equations, in our previous work we modeled the system as a port-controlled-Hamiltonian system, and a task-invariant controller was designed for a knee-ankle exoskeleton using interconnection-damping assignment passivity-based control. In this paper, we extend this framework to design a controller for a backdrivable hip exoskeleton to assist multiple tasks. A set of basis functions that contains information of kinematics is selected and corresponding coefficients are optimized, which allows the controller to provide torque that fits normative human torque for different activities of daily life. Human-subject experiments with two able-bodied subjects demonstrated the controller’s capability to reduce muscle effort across different tasks.",

A energy-based control scheme is developed to realize chaos synchronization in term of port- Hamiltonian systems, and the asymptotical stability for the closed-loop Hamiltonian system is derived by using the LaSalle’s invariance principle. It is shown that the developed energy-based synchronization scheme is relatively simple and easy to implement compared with some recent literatures. Finally, two simulation examples are performed to demonstrate the effectiveness of the proposed synchronization strategy method.",

      "abstract": "The relative position and velocity control problem of spacecraft formation flight (SFF)is a classically significant problem in the field of space control. In this paper, we propose a high-precision nonlinear dynamics model for spacecraft formation flight with J2 perturbation in the framework of the port-Hamiltonian (pH) system. And through the application of the PID passive-based control method (PID-PBC), we give a new controller design method for the dynamics of SFF. Applying the leader-multi-follower spacecraft architecture, we first establish a nonlinear spacecraft formation dynamics model in the pH framework in the Earth Centered Inertial framework, and then transform it to the LVLH frame to establish a spacecraft relative motion dynamics model, and retain the nonlinear structure and $J_{2}$ perturbation. Then a PID-PBC controller was established by constructing an additional system and designing a closed-loop Lyapunov function to ensure the stability of the target position. Numerical simulations show that the method is effective under the spacecraft formation reconfiguration mission.",

      "abstract": "This paper presents a novel approach for designing a composite controller that finite time simultaneously stabilizes two single input nonlinear Port-Controlled Hamiltonian (PCH) systems under disturbances. Firstly, using a single output feedback, two PCH systems are combined to generate an augmented PCH system based on the Hamiltonian structure properties. Then, a finite time disturbance observer (FTDO) is introduced to estimate disturbances and the estimation of disturbances is employed to feedforward compensate the disturbances. Next, a composite simultaneous stabilization controller is developed by combining the single output feedback, the FTDO and the finite time control techniques together. Finally, finite time stability analysis for the augmented PCH system is given. An example with simulations illustrates the effectiveness of the proposed method.",

The objective is solved by interconnecting agents with virtual couplings based on the internal principle, which can look into the energy consumption. Firstly, the controller for tracking estimated velocity is designed by ultilizing Hamiltonian theory. We assume that the desired velocity is time-varying and only known to part of the agents. Sencondly, an observer based on internal model is designed to overcome the input disturbances by adding extended states, while preserving the PCH form. Numerical simulation results are given to illustrate the effectiveness of the approach.",

Compared with the existed results, the proposed methods not only effectively deal with the Hamiltonian function having a local minimum, but also work out that the Hamiltonian function is not positive definite at the equilibrium point or not bounded from the below. Thus, the proposed methods enlarge the applications of PH systems subjected to AS. Finally, example is given to show the validity and advantage of the proposed methods.",

      "abstract": "This paper deals with the stabilizing control design for a class of micro-grippers for DNA manipulation using boundary controlled infinite-dimensional port-Hamiltonian systems. In practical applications, the controllers are implemented as finite-dimensional systems actuating at the boundaries of an infinite-dimensional system. The design of the finite-dimensional controllers is still a challenge, especially for hyperbolic PDEs. For this purpose, the LQG balancing reduction method is suitable for the reduced order control design since it considers the closed loop behavior in the reduction procedure. This paper presents the application of this recently proposed method combined with integral action in order to improve the robustness of the closed-loop system. It is shown by means of simulation that the addition of integral action effectively rejects constant perturbations while assuring global closed-loop stability.",

      "abstract": "This paper addresses identification of nonlinear circuits for power-balanced virtual analog modeling and simulation. The proposed method combines a port-Hamiltonian system formulation with kernel-based methods to retrieve model laws from measurements. This combination allows for the estimated model to retain physical properties that are crucial for the accuracy of simulations, while representing a variety of nonlinear behaviors. As an illustration, the method is used to identify a nonlinear passive peaking EQ.",

Lyapunov analysis is used with their state-space representations to guarantee zero-input stability over the range of parameters consistent with the actual circuits. A zero-input stable non-iterative discrete-time scheme based on a discrete gradient and a change of state variables is shown along with numerical simulations. Simulations show behavior consistent with the actual operation of the circuits, e.g., self-oscillation, and are found to be stable and have lower computational cost compared to iterative methods.",

The approach allows classical results from electrical circuit synthesis and analysis to be carried over exactly to the mechanical domain. It also enables one to apply (nonlinear) control techniques like Power Shaping as recently proposed in [7]. Illustrative examples are provided to facilitate the theoretical developments.",

Hence balancing will not yield any information about the relative importance of the state components in a balanced realization. This result is extended to the lossy case, indicating that balancing in this case will largely depend on the internal energy dissipation. By using the representation of passive systems as port-Hamiltonian systems a direction for extending standard balancing is discussed.",

The system representation has been extended to an infinite-dimensional conservative system derived from variational calculus, which is called a field-port-Lagrangian system. A lot of practical systems for control engineering include dissipative elements; however such a non-conservative structure usually cannot be defined by a variational problem. This paper shows that a system with the dissipative structure can be defined as a time-varying fieldport-Lagrangian system by a gauge transformation. First, we show that the gauge transformation generates a time-dependent Lagrangian density functional that introduces the time-varying port-representation. Next, we present that a class of dissipative systems can be identified with a conservative system possessing an internal irreversible energy flow. Finally, we illustrate an equation of elastic films with viscosity damping with the time-varying port-representation.",

This approach includes a feedforward part in the framework of Port-Controlled Hamiltonian Systems with Dissipation (PCHD systems). PCHD systems have turned out beneficially for the design of nonlinear controllers and provide special properties for the stability analysis of equilibrium points. By means of feedback control one may overcome model errors and disturbances for a real application. A passivity-based controller, which is designed for the PCHD error dynamics, exploits the mathematical structure of the system and forces the tracking error to zero. The combination of the feedforward and feedback part leads to a controller, which achieves good tracking behavior, cancels initial errors and rejects disturbances from the environment. The derivation of a control law which includes a feedforward part and a feedback controller will be shown for the nonlinear underactuated benchmark example Inertia Wheel Pendulum.",

Since port-Hamiltonian systems can describe a wider class of systems than conventional mechanical ones, the proposed method is applicable to various systems. Futhermore, we can control the velocity directly by this method while it is not possible with the conventional approach.",

Standard spatial discretization schemes for PDE systems have the disadvantage that they typically lead to a finite dimensional system which is not anymore in the pH form. So, there is a need for a spatial discretization scheme which preserves the structure of the system. The problem of spatially discretizing a pH system with constant Stokes-Dirac structures and quadratic energy functions was solved in the past. But here we consider a piezoelectric Euler-Bernouli with nonlinear deformation. So, the Stokes-Dirac structure and energy function of the system are also nonlinear, and this causes some additional problems.",

We identify (on the basis of the achievable Casimirs) the precise form of the so-called dissipation obstacle, and how this obstacle may be removed by changing the passive output. We also review the “swapping the damping” procedure for computing a new passive output, and show how this can be obtained as a special case within our approach.

Furthermore an integral controller is added to guarantee a vanishing output error. The Port-Hamiltonian approach leads to a control law as well as a Lyapunov function for the closed loop stability analysis.

      "abstract": "Mechanical systems can be asymptotically stabilized without velocity measurements by applying a dynamic extension. By interconnecting the system with a (virtual) controller damping is indirectly injected into the system making velocity measurements unnecessary, provided that this damping propagates to the mechanical system. The approach has been shown for the case of potential energy shaping and for a class of systems requiring total energy shaping. In this paper we investigate the same idea for the trajectory tracking problem. Like with the stabilization problem we apply a dynamic extension to avoid having to measure the system velocities and still realize perfect tracking of a desired trajectory. This is done for fully-actuated port-Hamiltonian mechanical systems.",

It is shown that the reduced order models inherit the port-Hamiltonian structure, the passivity property and preserve a certain number of the moments of a transfer function. Another approach to model reduction of port-Hamiltonian systems by means of the Krylov methods is considered. It is shown that in this case reduced order models are again port-Hamiltonian and therefore passive. The port-Hamiltonian structure of the reduced order models in both cases is investigated.",

Based on a variational principle we derive the equations of motion as well as the boundary conditions in the well-known Lagrangian framework. Then it is of interest to reformulate the equations of motion in a port-Hamiltonian setting, where we compare the approach based on Stokes-Dirac structures to a Hamiltonian setting that makes use of the involved bundle structure similar to the one on which the variational approach is based. We will use the Mindlin plate, a distributed parameter system with spatial domain of dimension two, as a running example.",

      "abstract": "In this paper we apply port-Hamiltonian theory with the bondgraph modelling approach to the problem of formation control using partial measurements of relative positions. We present a control design that drives a group of vehicles to a desired formation without requiring inter-vehicle communications or global position and velocity measurements to be available. Our generic approach is applicable to any form of relative measurement between vehicles, but we specifically consider the important cases of relative bearings and relative distances. In the case of bearings, our theory closely relates to the field of image-based visual servo (IBVS) control. We present simulation results to support the developed theory.",

      "abstract": "Boundary controlled-port Hamiltonian systems have proven to be of great use for the analysis and control of a large class of systems described by partial differential equations. The use of semi-group theory, combined with the underlying physics of Hamiltonian systems permits to prove existence, well-possessedness and stability of solutions using constructive techniques. On other hand, the differential geometric representation of these systems has lead to finite dimension approximation methods that conserves physical properties such as the interconnection structure and the energy. These results are applied to the modelling and control of a class of nanotweezers used for DNA-manipulation. The Nanotweezer may be modelled as a flexible beam interconnected with a finite dimensional dynamical system representing the manipulated object. A boundary controlled-port Hamiltonian model for the ensemble and an exponentially stabilizing controller are proposed. A geometric approximation scheme is used to reduce the infinite dimensional system and numerical simulations of the closed-loop system presented.",

      "abstract": "In this paper, we show the equivalence between a constrained, multi-agent control problem, modeled within the port-Hamiltonian framework, and an exact potential game. Specifically, critical distance-based constraints determine a network of double-integrator agents, which can be represented as a graph. Virtual couplings, i.e., pairs of spring-damper, assigned to each edge of the graph, allow to synthesize a distributed, gradient-based control law that steers the network to an invariant set of stable configurations. We characterize the points belonging to such set as Nash equilibria of the associated potential game, relating the parameters of the virtual couplings with the equilibrium seeking problem, since they are crucial to shape the transient behavior (i.e., the convergence) and, ideally, the set of achievable equilibria.",

Three control problems for complex systems consisting of port-Hamiltonian subsystems are formulated. In particular, the problem of exciting a number of identical port-Hamiltonian systems to given (not necessarily equal) energy levels while ensuring strict bounds on the energy levels of remaining systems is studied. Solvability conditions based on speed-gradient control are established. The obtained results are illustrated by numerical simulations.",

Lately, for a class of mechanical systems an energy shaping controller has been investigated that avoids PDEs by exploiting implicit port-Hamiltonian representations. Following the same research line, in this paper we generalize the total energy shaping IDA-PBC for underactuated mechanical systems in the implicit framework and propose an algebraic solution for a class of systems. Besides, under some additional conditions we are also able to produce a respective output feedback. A reduction of the closed loop system in explicit coordinates is presented. We test our results on the inclined cart-pole system and portal crane.",

      "abstract": "In this work we propose a virtual contraction-based control (v-CBC) design approach to the tracking problem in marine craft modeled as port-Hamiltonian (pH) systems. The design method consists of three main steps: i) construct a virtual control system which has all the original marine craft pH model's solutions embedded; ii) design a control law that makes the virtual control system contracting with a desired steady-state trajectory; iii) close the loop of the original marine craft pH model with above controllers. Due to the rigid body nature of marine craft, two v-CBC schemes are proposed; one in a body frame and another in an inertial frame. We show how the intrinsic structure of pH models and their workless forces can be exploited to construct virtual control systems for marine craft in both frames. The closed-loop system's performance is evaluated on simulations.",

In this paper we study a subclass of linear first order port-Hamiltonian systems. In [3], it is shown that these systems are exactly observable when the energy is not dissipated internally and when sufficient observations are made at the boundary. In this article we study the observability properties for these systems when internal dissipation of energy is possible. We cannot show the exact observability, but we do show that the Hautus test is satisfied. In general, the Hautus test is weaker than exact observability, but stronger than approximate observability. Hence we conclude that these systems are approximately observable.",

      "abstract": "The induction machine is used in a wide variety of applications as a means of converting electrical energy into mechanical work and vice versa. There is an increasing use of the machine configured as a generator in unconventional wind and micro-hydro energy systems. The advantages of the system range from low cost to simplicity of construction, operation, and maintenance. This work provides a generalization to the port-Hamiltonian model of a squirrel-cage induction motor based on a synchronously rotating reference frame of d-q axes. Furthermore, the port-Hamiltonian formalism is used to provide a modeling approach to a self-excited induction generator which is also deduced for the d-q stationary reference frame. The performance our modeling approach is validated via numerical simulations.",

In each iteration, a new reduced-order model is computed, which might weaken the computational advantages in cases of slow convergence. We propose a new structure-preserving framework for port-Hamiltonian systems based on surrogate modeling. By exploiting the local nature of the ${{\\mathcal{H}}_2}$-optimization problem, the cost of optimization is decoupled from the cost of reduction. Consequently, ${{\\mathcal{H}}_2}$-based interpolatory methods can be accelerated significantly and especially for very large-scale port-Hamiltonian systems, which is illustrated by a numerical example.",

The stabilizing controller features the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) method with an optimal local assignment. The swing-up controller is derived from the so-called energy-based control approach and underlines the stabilization of a level-set (homoclinic orbit). The combination of these controllers guarantees the swing-up and asymptotic stabilization of the upright pendulum position, as well as the desired cart location. The effectiveness of the proposed control scheme is verified via real-time experiments, and the results are compared with those from other authors.",

To this end, we propose a Lyapunov candidate function different from the Hamiltonian of the system. Moreover, we study how the proposed analysis can be used to determine the exponential stability and the rate of convergence of some (nonlinear)-mechanical systems stabilized by a passivity-based control technique, namely, PID passivity-based control. We implement such a control approach to stabilize a three-degree-of-freedom robotic arm at the desired equilibrium point to illustrate the mentioned analysis.",

We decompose the model into two dual subsystems both having positive linear first integrals representing conservation. Based on the dynamics of the reaction network we construct a port-Hamiltonian representation of the system in the original and also in the reduced state spaces with clear connection between the structure matrices and the compartmental graph topology. We finally demonstrate that the system is non-expansive in the -norm both in the original and in the reduced state spaces. The generality of our approach ensures that the results are valid for a wide class of reaction rate functions used in the CRN representation.",

The control law consists of two parts, where the internal feedback is to track the velocity and the external feedback is to achieve formation stabilization. Since the dynamics of the controller are associated with the edges, the stability analysis is related to the kernel of the incidence matrix $B$ of the underlying graph. For displacement-based formations, the approach is applicable not only to acyclic graphs, but also to cyclic graphs, in which case the columns of $B$ are not linearly independent. For rigid formations, the passivity approach for distance and bearing formation is proposed. In addition, the relationship between infinitesimal rigidity and convergence of the desired formation is established. The proposed approach is verified by numerical simulations.",

The proposed approach builds on the simultaneous interconnection and damping assignment method and takes advantage of the representation of the dissipative forces in the port-Hamiltonian dynamics. We consider dissipative forces that cannot be written in the classical dissipation structure of the port-Hamiltonian systems. We show that the proposed design ensures the stability of the equilibrium and is robust against dissipative force uncertainty, and rejects constant matched disturbances. Two case studies are presented, and simulation results show the closed-loop performance.",

The first contribution resides in the CbI-oriented formulation of the augmented system, including the plant and the observer. It explicitly supplies observed states as output, which serves to freely design any state-feedback controller. Then, for the second contribution, the CbI-MPC control design is adapted to take into account this augmented PH system. Hence, a new controller input matrix is proposed with corresponding matching conditions. The proposed control method is validated through simulation results for a 3-phase Permanent Magnet Synchronous Motor with input and state constraints.",

To that end, we first present a methodology to find the nearest negative imaginary system for a given non-negative imaginary system. Then, we employ this result to construct a near optimal linear quadratic Gaussian controller achieving desired performance measures. The problem is formulated using port-Hamiltonian method and the required conditions are defined in terms of linear matrix inequalities. The technique is presented using fast gradient method to solve the problem systematically. The designed controller satisfies a negative imaginary property and guarantees a robust feedback loop. The effectiveness of the approach is demonstrated by simulation on a numerical example.",

      "abstract": "This paper focuses on the problem of resilient phase angle stabilization and frequency synchronization in converter-based microgrids, utilizing phasor measurement units (PMUs), in the presence of false data injection (FDI) cyberattacks. The uniformly bounded cyber-attack signals are inserted to desynchronize converters and violate frequency constraints by manipulating control input channels. To tackle this issue, a resilient and robust cooperative angular control scheme is proposed by modifying the conventional angular control method and incorporating some auxiliary states interconnecting with physical states. By presenting the converter dynamics along with the proposed controller as a port-Hamiltonian (pH) system, the design considerations of the interconnection matrices are outlined. Theoretical analysis using input-output passivity and $H_{\\infty}$ norm performance index are carried out to guarantee asymptotic stability and resilient frequency synchronization against FDI attacks. The performance and effectiveness of the proposed control scheme are evaluated through numerical simulations",

The investigation produces a structure-preserving reduced-order model if certain additional passivity conditions are satisfied. Moreover, such an investigation provides a different insight into the standard Singular Perturbations approach relating the negligible time constant parameters $\\varepsilon$ to energy parameters. We analyze the deviation between the complete system model and the reduced one via a Lyapunov-based approach. We then conclude the paper by applying the proposed reduced order model to a DC-motor example to show the effectiveness of the development.",

      "abstract": "In this paper, we adopt an energy perspective to analyze the stability of converter-dominated dc grids under a hierarchical (primary/secondary) optimal control strategy based on distributed communications, and its robustness against cyber-threats. First, we begin by showing that both the decentralized droop-controlled de microgrid, as well as the distributed secondary controller, admit a port-Hamiltonian description. Second, we exploit the fact that the closed-loop system can be interpreted as a lossy-interconection between their (incremental) models to prove stability for the unperturbed system. Third, we analyze the effect of malicious attacks on the (linear) system and robustify the control system such that resilience against cyber threats always is ensured at steady state. Additionally, we show that by adequately tuning the controllers we are able to significantly reduce the attack influence on the desired steady state. Finally, we use time-domain simulations to support our findings in a case study involving a low-voltage DC microgrid.",

      "abstract": "Modern power systems include inverter-based resources that may reduce equivalent inertia, resulting in instability issues. A common way to add inertia is by increasing the energy storage capacity in each inverter. Although viable, this option may be expensive in practice. This article proposes a new approach to improve stability in grid-forming inverters. The conventional droop of frequency/power is equipped with additional angle feedback based on the port-Hamiltonian structure of the dynamic system. Phasor-measurement units allow this type of control. The control proofs to be asymptotically stable for a single-inverter infinite bus system. Simulation results under different fault conditions demonstrate a superior performance of the proposed control compared to a conventional droop.",

State averaging method is adopted to transform the nonlinear system of the improved Y-source grid-connected inverter into a hamiltonian model. According to the control objectives of the system, equilibrium points of the system are determined, then the system controller is designed using interconnection and damping assignment method. Finally, a 200W laboratory prototype is built based on a TMS320F2812 digital signal processor to verify the performance of the control method.",

Firstly, the Port Control Dissipative Hamiltonian (PCHD) model is established for D-PMSG, which simplifies the design of controller. Then, a global High-order Non-singular Terminal Sliding Mode (HNTSM) controller is designed to realize the Maximum Power Point Tracking (MPPT) below the rated wind speed, and it has much faster response speed and better robustness compared with PI controller. However, in the parameters design of PCHD controller, there is no specific selection criterion, so it is difficult for the parameters selected by experience to achieve the ideal effect. Therefore, the hybrid particle swarm optimization algorithm (HPSO) is used to optimize the parameters of PCHD controller, so that the control effect is faster and more accurate. Simulations validate the proposed control.",

The procedure has a general form and is applicable to spacecraft's attitude motion described with quaternion parameters. This paper investigates the roles of several design parameters in the generalized canonical transformations. Special attention is placed on the relation between the shape of Lyapunov functions and the convergence speed of the state variables. Furthermore, from the analysis utilizing the linearized form of the Port-controlled Hamiltonian system, the guideline to decide the preferable ratio between two parameters in the design procedure is proposed.",

One of the methods for creating models is to represent the model by neural networks and train them in accordance with the data. However, the model created by machine learning cannot always satisfy the physical properties of the system. If some prior knowledge can be imposed on the estimation, it can be beneficial in the application of the obtained model and the reduction of the burden needed for the training. In this paper, we propose the new method to reflect the passivity of the system by using a port-Hamiltonian form. The effectiveness of the proposed method is shown via numerical examples.",

      "abstract": "Soft-switching technologies can effectively solve the problem of switching losses caused by increasing switching frequency of grid-connected inverters. As a branch of soft-switching technologies, load-side resonant soft-switching is a hotspot for applications of high-frequency inverters, because it has the advantage of achieving soft-switching without using additional components. However, the traditional PI control strategy based on the linear model is prone to destabilization and non-robust dynamic performance when large signal perturbation occurs. In this paper, a novel Passivity-Based Control (PBC) method is proposed to improve the dynamic performance of load-side resonant soft-switching grid-connected inverter. Besides, the model based on the Port Controlled Hamiltonian (PCH) model of the soft switching inverter is carried out, and the passivity-based controller is designed based on the established model using the way of interconnection and damping assignmentpassivity based control (IDA-PBC). Both stable performance and dynamic performance of the load-side resonant soft-switching inverter can be improved over the whole operating range. Finally, a 750 W load-side resonant soft-switching inverter simulation model is built and the output performance is compared with the traditional PI control strategy under stable and dynamic conditions. The simulation results show that the proposed control strategy reduces the harmonic distortion rate and improves the quality of the output waveforms.",

Power converters on the other hand are devices that process the electrical energy at its input to deliver energy with the required characteristic at its output. Hence, a Port-Hamiltonian model is especially attractive for control of power converters. Based on previous published results, in this paper, a Port-Hamiltonian approach is proposed for the control of DC-DC power converters. A particular characteristic of the controller here proposed is that a time variable inductor current is employed. As a result a faster and lower overshoot closed loop response is obtained for both the start-up condition and the load disturbance.",

      "abstract": "Electrodynamic tethers provide actuation for performing orbit correction of spacecrafts. When an electrodynamic tether system is orbiting the Earth in an inclined orbit, periodic changes in the magnetic field result in a family of unstable periodic solutions in the attitude motion. This paper shows how these periodic solutions can be stabilized by controlling only the current through the tether. A port-controlled Hamiltonian formulation is employed to describe the tethered satellite system and a passive input-output connection is used in the control design. The control law consists of two parts: a feedback connection, which stabilizes the open-loop equilibrium; and a bias term, which is able to drive the system trajectory away from this equilibrium, a feature necessary to obtain orbit adjustment capabilities of the electrodynamic tether. It is then shown how the periodic solutions of the closed-loop system can be approximated by power series, and a relation is found between control gain and perturbations around the open-loop solution. Stability properties of the system are investigated using Floquet analysis, and the region of stability is found in the plane defined by the control parameters.",

      "abstract": "The boom systems of mobile cranes and aerial platform vehicles are driven by hydraulic systems, to be specified, valve-controlled hydraulic cylinders. This hydraulic actuated boom system can accomplish the tasks such as lifting heavy loads or carrying personal to high position, by the design of a long boom structure. In practice, the boom structure is designed as light and slender as possible to control the structure self-weight. However, such structure is quite flexible and can be easily stimulated by the loads, including the driving force or torque from the hydraulic system. Our research focus es on trajectory planning for hydraulic actuated boom where both hydraulic driven system and boom structure deformation are considered. In this paper, the hydraulic actuated boom system is formulated as a port-Hamiltonian system which is a proper modelling method for multi-domain system. The problems of trajectory optimization and vibration control are formulated as optimal control problem based on port-Hamiltonian model and this procedure is tested on a model of hydraulic cylinder. A reasonable result is solved with the selected cost function and inputs.",

      "abstract": "Subscale flight testing requires control and identification of unmanned aerial vehicles, in turn, these two aspects both require a competent dynamic model of the system. This work uses the port-based Bond Graph graphical modeling framework to model and simulate the dynamics and aerodynamics of a fixed wing unmanned aerial vehicle (UAV). This model is used to design a total energy compensated based controller (TECS) and to perform system identification using the Output Error Method (OEM). The platform of this work consists of two UAVs, a subscale model of a BAE Hawk fighter jet and a commercially available drone, the Vector-P. These UAVs are used to determine the aerodynamic derivatives and compare these with simulations, wind tunnel and real airplane data. Proper subscale flight testing requires repetitive steady flight conditions, which can only be properly realized using a stabilizing autopilot. The multidisciplinary nature of UAVs make them especially suitable for modeling using bond graphs, a universal domain-independent energy and port- based modeling framework. The explicit representation of energy in bond graph modelling matches very well with TECS control and provides valuable insights in controller operation and opens new doors to future UAV controlling techniques based on Port Hamiltonian systems.",

The purpose of this study is to obtain differences in the dynamics of mechanical systems with non-holonomic constraints in various flat and curved configuration spaces based on physics computing. In this study the reduction used is a mathematical calculation of the Port-Contolled Hamiltonian System (PCHS) equation in a mechanical system that is a Stroller, so that the equation used in determining the Stroller motion equation with and without friction that moves in the curved plane in the form of a spherical surface with various initial conditions based on maple is Poincaré's equation which is based on Routhian reduction with and without friction. The effect of friction can be clearly seen through dynamics and graphical equations on the Stroller. This method can reduce the Stroller motion equation with and without friction that moves on the ball sphere clearly in the form of a set of differential equations. The findings of this study are dynamic equations and graphs of Stroller equations with and without friction that move in the curved plane in the form of a spherical ball with varying initial conditions based on maples. This study proves physical concepts about dynamics and kinematics and analyzes Stroller dynamics using computational physics to determine the characteristics of complex and complex Stroller movements, both translational and rotational.",

Such dynamics are considered to be re-expressed in a canonical form, namely the port-Hamiltonian (pH) representation with dissipation, where the Hamiltonian is a quadratic function and has the unit of energy or power. On this basis, it allows revealing the transformation of energy (or power) inside the system, including the energy supply, storage and dissipation, thereby facilitating Lyapunov-based or energy-related control approaches for stabilization and optimization purposes. Two pH representations are proposed and compared; the first one is established with difficult-to-measure states while the second one is obtained with easier-to-measure states.",

The controller design is founded on an energy-based formulation of the mathematical model, taking into account the fundamental relations of an isentropic fluid. The control law guarantees that the errors of the piston position, the velocity and the piston force asymptotically approach zero and that the desired equilibrium of the overall closed-loop system is stable. By means of an industrial simulation software for hydraulic systems extensive simulation tests have been performed, also considering the robustness with respect to parameter variations and measurement noise. In all cases, the results prove the feasibility and the practical usefulness of the concept being proposed.",

The basic strategy of this approach is to construct an error system, which describes the dynamics of the tracking error, by a passive port-controlled Hamiltonian system.

      "abstract": "Energy shaping and passivity-based control designs have proven to be effective in solving control problems for underactuated mechanical systems. In recent works, interconnection and damping assignment passivitybased control (IDA-PBC) has been successfully applied to open-loop conservative models, that is, with no physical damping (e.g. friction) present. In a number of cases, in particular when IDA-PBC control only involves potential energy shaping, the actual presence of physical damping will not compromise the achieved closed-loop stability. However, when IDAPBC control also includes the shaping of the kinetic energy, closed-loop stability or even passivity for the model without physical damping may be lost if physical damping is present. This raises two fundamental questions. First, in which cases is the IDA-PBC controlled system designed on the basis of the undamped model still stable and passive when physical damping is present? Second, if this is not the case, when is it possible to redesign the IDA-PBC control law for the undamped systems such that stability and passivity are regained? This paper provides necessary and sufficient conditions for the existence of such a control redesign for a particular choice of the closed-loop energy function. Furthermore, if these conditions are satisfied then two methods for redesign are presented, which can be chosen depending on the problem structure and the parameter uncertainties. Finally, even in the cases where the addition of physical damping does not hamper the stability properties of the IDA-PBC design based on the undamped model, we show that the aforementioned redesign is still useful in order to reduce the mathematical complexity in exponential and asymptotic stability analysis.",

      "abstract": "We consider a doubly-fed induction machine – controlled through the rotor voltage and connected to a variable local load – that acts as an energy-switching device between a local prime mover (a flywheel) and the electrical power network. The control objective is to optimally regulate the power flow, and this is achieved by commuting between different steady-state regimes. We first show that the zero dynamics of the system is only marginally stable; thus, complicating its control via feedback linearization. Instead, we apply the energy-based Interconnection and Damping Assignment Passivity-Based Control technique that does not require stable invertibility. It is shown that the partial differential equation that appears in this method can be circumvented by fixing the desired closed-loop total energy and adding new terms to the interconnection structure. Furthermore, to obtain a globally defined control law we introduce a state-dependent damping term that has the nice interpretation of effectively decoupling the electrical and mechanical parts of the system. This results in a globally convergent controller parameterized by two degrees of freedom, which can be used to implement the power management policy The controller is simulated and shown to work satisfactorily for various realistic load changes.",

More in detail, we show how to design a controller able to guarantee the asymptotic tracking of partially unknown exogenous trajectories belonging to a given family, embedding in the regulator the internal model of this family; the control algorithm is able to attain the asymptotic tracking without the knowledge of reference derivatives and exploiting only instantaneous error feedbacks. The theoretical machinery exploited is the nonlinear regulation theory, specialized for the energy-based port- Hamiltonian formalism. The same methodology is proved to be able to deal even with the presence of exogenous voltage disturbances superimposed to the control voltages.",

It is shown how to choose the projection matrices in order to guarantee the moment matching property and to obtain a passive and thus stable reduced-order model in port-Hamiltonian form. The method is suitable for the reduction of largescale systems as it employs only the well-known Arnoldi algorithm and matrix-vector multiplications to compute the reduced-order model. Afinite element model is reduced to illustrate the new method.",

      "abstract": "In this article a control algorithm for the reduced port-Controlled Hamiltonian model (PCH) of the shallow water equations partial differential equations (PDEs) is developed. This control is developed using the Interconnection and Damping Assignment Passivity Based Control (IDAPBC) method on the reduced PCH model without the natural dissipation. It allows to assign desired structure and energy function to the closed-loop system. The same control law is then derived using an energy-shaping method based on Casimir's invariants, associated with a particular conservative interconnection between the boundary variables. This gives a physical interpretation for the designed controller. Finally, a stability analysis of the dissipative system in closed loop with the designed control is done using LaSalle's invariance principle. Simulation results and an experimental validation of the control algorithm on an a micro-canal platform are presented showing the effectiveness of the control law.",

We show how the choice of a new passive input-output pair for a PHSD is reflected in a new Dirac structure. We define a general class of new passive inputoutput pairs for a PHSD and subsequently compute (in a constructive manner) the resulting new Dirac structure and examine the achievable Casimirs for this new Dirac structure. We focus on the special case where only the passive output is changed (while retaining the original input) and subsequently define a general class of new passive outputs for the PHSD. We then identify (on the basis of the achievable Casimirs) the precise form of the so-called dissipation obstacle, and how this obstacle may be removed by changing the passive output.We also review the “swapping the damping” procedure for computing a new passive output, and show how this can be obtained as a special case within our approach. We finally consider the examples of the RLC-circuit and MEMS optical switch to investigate the role played by the new class of passive outputs in shaping the system's energy.",

This leads to the notion of implicit Brayton-Moser equations. Furthermore, the form and existence of the mixed-potential function is rederived from an external port point of view.",

      "abstract": "In this paper, a passive control scheme for port Hamiltonian systems with dissipation (PHD) is presented. The control scheme is able to conserve the PHD structure of the system when constrained on a sub-manifold of the state space. The idea is to modify both the interconnection and damping structures of the system and to add a proper dynamical extension in such a way that the constraint can be related to some dynamical invariants of the resulting closed-loop system. Since part of the structure of this dynamical extension can be arbitrarily chosen, it is also possible to drive the state of the system on the constraint and to obtain the dynamical behavior defined by the constraint. For example, if a proper variable structure dynamical extension is chosen, it is possible to achieve a sliding-mode behavior that can be interpreted by means of energetic considerations.",

The nonlinear feedback controls, derived by using the approaches that have been recently developed, based on the port controlled hamiltonian (PCH) structure, are compared to the one derived by the methods based on the eigenstructure proposed by the author in previous work. The aim is to emphasize that, using the second approach appears as a particular case than using the first approach. Moreover, the results have been applied to derive the control laws of a launcher in the phase outside the atmosphere. It may be interesting to observe that the coefficients of the damping matrix, involved in PCH approach, have not the same effect on the system sensitivity. This paper somehow extends the related one presented by the author at the IFAC symposium in aerospace control.",

      "abstract": "In the standard approach of control by interconnection the plant and the controller are assumed to be passive and coupled via a power-preserving interconnection-generating an overall passive system with storage function the sum of the plant and controller storage functions. To achieve stabilization of a desired equilibrium one must make this point a minimum of the new storage function. Towards this end, dynamic invariants—called Casimirs—are first computed. Restricting the dynamics to the level sets of the Casimirs, the overall storage function becomes a bona fide function of the plant states and the storage function can be shaped. Unfortunately, this procedure is applicable only if one fixes the initial conditions of the controller to some specific values. To remove this drawback we propose in this paper to carry out the stability analysis in the full plant and controller state spaces. The new storage function is then the sum of the plant and the controller Hamiltonians and an arbitrary functions of the corresponding Casimir functions. We also provide some examples which illustrate the possibilities and limitations of the new method.",

First, in order to obtain a dynamic feedback, an integrator is added to the system via a generalized canonical transformation.

An output feedback stabilization method is derived based on this equivalence. Furthermore, some numerical examples show the effectiveness of our technique.",

The control by interconnection and energy shaping is applied to the stabilization of a distributed parameter system by means of a finite dimensional controller.

The key point is the generalization of Casimir function for systems resulting from the power conserving interconnection of an infinite and a finite dimensional part.",

      "abstract": "Either from a control theoretic viewpoint or from an analysis viewpoint it is necessary to convert smooth systems to discrete systems, which can then be implemented on computers for numerical simulations. Discrete models can be obtained either by discretizing a smooth model, or by directly modeling at the discrete level itself. One of the goals of this paper is to model port-Hamiltonian systems at the discrete level. We also show that the dynamics of the discrete models we obtain exactly correspond to the dynamics obtained via a usual discretization procedure. In this sense we offer an alternative to the usual procedure of modeling (at the smooth level) and discretization.",

IDA-PBC provides sometimes control laws that are complicated and/or need all state measurement. In this paper, Disturbed-PCHD systems are considered where IDA-PBC is applied. Two sufficient stability conditions on the disturbances are given. Moreover, this approach allows to study controller robustness against parameters uncertainties. This new approach simplify the control law and allows to deal with unmeasured terms. Application of this new approach to the control of the voltage-fed Induction Machine (IM) is presented.",

On the other hand, port-controlled Hamiltonian systems (PCHS) describe, in a modular, network-like way, the interconnection of physical systems using the transfer of energy as the unifying concept. In this paper, a relationship between the PCHS structures of a system and its GSSA expansion is established for a class of Hamiltonians (which includes the quadratic ones), and this is used to design controls from a GSSA truncation which, under certain restrictions, can be used for the full original system.",

Although we have only a few control input for the infinite-dimensional system of a hyper-flexible body, we provide an illustrative control example where we can achieve damping injection to a planar cable-like hyper-flexible body by only translational acceleration input at its one end.

      "abstract": "hybrid system of a fuel cell (FC) and batteries connected to a non-linear load is presented. FC do not work properly under transient conditions. The sharp changes in the load power demand cause sever electrochemical and thermal non-uniformities in FC. These non-uniformities increase the degradation rate of FC and reduce its expected life span. To mitigate these detrimental effects, a battery bank is used along with FC. This paper deals with the state space modeling of the hybrid system, and the control of the DC Bus voltage by the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC). IDA-PBC is a useful technique to control systems assigning a desired Port-Controlled Hamiltonian (PCH) structure to the closed-loop. The global stability proof and simulation results are presented.",

A wide variety of mechatronic systems are controlled by operating dissipative components and the standard approaches for the control of port Hamiltonian systems are not applicable. Facing the limitation that the controlled devices can only dissipate power, the issue is to find a proper control law to satisfy the control requirements. This paper proposes to choose the control inputs to lead the input power of a subsystem in oder to satisfy the requirements by controlling the energy stored or the power dissipated in that subsystem. A slight extension of the definition of port Hamiltonian system is proposed to allow the description of a larger set of mechatronic systems. Although some important issues remain open, the example of the semi-active suspension shows that some positive results can be achieved by applying the proposed approach.",

The energetic performances of batteries make them efficient, but for supplying pulsating loads, supercapacitors must be added. In this paper, the design of the system is presented and the dynamic model is described using the Port-Hamiltonian formalism. The Passivity-Based Control strategy is proposed according to achieve the best energy management of the system. Simulation results of the system processes are presented in order to prove that the model and the control strategy applied can ensure the global system stability.",

      "abstract": "It is well known that the dynamics of many physical processes can be suitably described by Port–Hamiltonian (PH) models. In this paper we consider the Passivity–Based Control (PBC) technique of Control by Interconnection (CbI), where the controller is another PH system connected to the plant to add up their energy functions. We propose two extensions to this method, first, we exploit the non–uniqueness of the PH representation of the system to generate new cyclo–passive outputs. Applying CbI through these new port variables overcomes the so–called dissipation obstacle. Second, when the plant state variables are measurable, we show that the conditions for applicability of the method can be relaxed replacing the simple unitary feedback by a state–modulated interconnection. A central contribution of the paper is the proof that the conditions for energy shaping via CbI are equivalent to those imposed in Interconnection and Damping Assignment PBC, providing in this way a nice geometric interpretation to this successful controller design technique.",

The starting point is a model in distributed port Hamiltonian form that, differently from the Euler-Bernoulli or Timoshenko beam, is able to describe large deflections in 3-D space. The spatial discretization technique is based on physical considerations so that, by exploiting the geometric structure of a distributed port Hamiltonian system, a finite dimensional approximation still in port Hamiltonian form that obeys to the same energy balance relation of its infinite dimensional counterpart can be obtained.",

A Port-Controlled Hamiltonian (PCH) representation is given for each component of the network and its dissipativity properties are shown. The linear model around the equilibrium is shown to meet a convex condition in the frequency domain, able to be exploited in the stability analysis of interconnected systems. The application of this property to a classical example shows that it can be computationally exploited even in the case of non-idealized models.",

Port-Hamiltonian systems provide some special mathematical properties and have turned out beneficial for the stability analysis of nonlinear control systems. The combination of a feedforward and feedback controller allows us to achieve good tracking and the rejection of disturbances and parameter variations. In addition the extension of the nonlinear control scheme with a state observer allows a reduction of the number of measured quantities. This approach will be shown for the example Ball on the Wheel.",

      "abstract": "This paper shows that one of soft actuators, Ionic Polymer-Metal Composite (IPMC) can be modeled in terms of distributed port-Hamiltonian systems with multi-scale. The physical structure of IPMC consists of three parts. The first part is an electric double layer at the interface between the polymer and the metal electrodes. The frequency response of the polymer-metal interface shows a fractal degree of gain slope. Then we adopt a black-box circuit model to this part and give considerations for distributed impedance parameters. The second part is an electrostress diffusion coupling model with bending and relaxation dynamics. This part is represented by an electro-osmosis, which is a water transport by an electric field, and a streaming potential, which is an electric field created by a water transport. We discuss the relationship of stress and bending moment induced by swelling. The third part is a mechanical system modeled as a flexible beam with large deformations. The representation has the capability extracting the control structure based on passivity from distributed parameter systems possessing a complex behavior.",

The Hamiltonian structure of the closed loop system is preserved and asymptotic stability of the mechanical position is achieved, which is verified by digital simulations.",

This work is the natural complement of Macchelli et al. [2006, 2007a], in which only the mathematical modeling aspects of such kind of devices have been discussed. This paper tries to show how the port Hamiltonian framework can be instrumental also for the easy implementation of efficient simulations if proper packages able to deal with the a-causality of port-based modeling techniques are used. In fact, once the main components (i.e. rigid and flexible links and kinematic pairs) have been created, the complete model just follows by port interconnection in a plug-and-play fashion. Then, it is the simulation engine that solves the causality of the overall scheme and generate the simulation code. The main steps are illustrated in detail with an example.",

In particular, this work focuses on the development of a port-based Hamiltonian model of the V2E2 and presents an optimal control architecture which exploits the intrinsic hybrid characteristics of the actuator design.

This structured modeling shows how the opposite of the entropy can be used as Hamiltonian function and how the associated dissipation can be related to the irreversible entropy production due to chemical reaction. The IDA-PBC approach based control is then applied to stabilize the continuous system about an unstable equilibrium point. The chosen control variables are the jacket temperature and the inlet molar flow rate. The chosen hamiltonian storage function of the closed loop system is the thermodynamic availability function. Theoretical developments are illustrated on a first order chemical equilibrated reaction. Some stability properties and analysis of the admissibility of the control variables are given.",

Stochastic port-Hamiltonian systems are extension of deterministic port-Hamiltonian systems, which are used to express various deterministic passive systems. However, since only time-invariant case has been considered in our previous results, the aim of this paper is to extend them to time-varying case. Finally, we propose a stabilization method based on passivity and the stochastic generalized canonical transformation, which is a pair of coordinate and feedback transformations preserving the stochastic Hamiltonian structure.",

The first is the representation in Riemann invariants coordinates whose representation has been applied successfully for the stabilization of linear and non-linear of such hyperbolic systems. The second representation is based on physical modelling and leads to port Hamiltonian systems which are extensions of infinite-dimensional Hamiltonian systems defined on Dirac structure. The stability conditions on the boundary feedback relations derived with respect to the Riemann invariants are interpreted in terms of the dissipation inequality of the Hamiltonian functional.",

These systems arise naturally in chemistry, but can also be used to model dynamical processes beyond the realm of chemistry such as in biology, ecology, geology, and physics. In this paper, by adopting the viewpoint of port-based modeling, we cast reaction-diffusion systems into the port-Hamiltonian framework. Aside from offering conceptually a clear geometric interpretation formalized by a Stokes-Dirac structure, a port-Hamiltonian perspective allows to treat these dissipative systems as interconnected and thus makes their analysis, both quantitative and qualitative, more accessible from a modern dynamical systems and control theory point of view. This modeling approach permits us to draw immediately some conclusions regarding passivity and stability of reaction-diffusion systems. Furthermore, by adopting a discrete differential geometry-based approach and discretizing the reaction-diffusion system in the port-Hamiltonian form, apart from preserving a geometric structure, a compartmental model analogous to the standard one is obtained.",

Beside the intrinsic difficulties related to the large number of state variables, the finite element model is generally given in terms of a Dirac structure and is completely a-causal, which implies that the plant dynamics is not given in standard input-state-output form, but as a set of DAEs. Consequently, the passivity-based methods have to be extended in order to deal with dynamical systems with constraints, usually appearing in the form of Lagrangian multipliers.",

This is done both in the isothermal and non isothermal cases. It is shown that Gibbs free energy and opposite of entropy can be chosen as Hamiltonian function respectively. For the non isothermal case, the so called Interconnection and Damping Assignment Passivity Based Control method is applied. Even for a general reaction the control problem is shown to be easy to solve as soon as closed loop hamiltonian function is chosen to be proportional to the so called thermodynamic Availability function.",

This research is part of a wider activity carried out in collaboration with Tetra Pak concerning the modelling and simulation of the Ultrasonic Sealing System (USTS). Due to the presence of a Compact Transducer (CT) that can be modelled only by means of commercial finite element CAE software, which provide extremely high-order dynamical systems, it is not possible to perform a simulation of the complete system to test the validity of the controller and perform the diagnosis of the sealing process in detail. The proposed procedure drastically reduces the simulation time without loosing the essential dynamical information. The model reduction algorithm is experimentally validated.",

A port-Hamiltonian system with dissipation (PHSD) is formed by the composition of a Dirac and a resistive structure. We show how the choice of a new passive output for a PHSD is reflected in a new Dirac structure. We generate a new class of passive outputs for a PHSD by changing the Hamiltonian function, interconnection and damping matrices and subsequently compute the new underlying Dirac structure. We next consider power conserving interconnections of two port-Hamiltonian systems and extend the (well known) standard feedback interconnection by considering interconnections between port-Hamiltonian systems which involve their energy storing ports, resistive ports and external ports. For port-Hamiltonian systems with dissipation, we demonstrate how these interconnections can be used for their closed-loop stabilization by the control-by-interconnection (CbI) method. Finally, we discuss the similarities between our (new) control by interconnection method and the (well-known) interconnection and damping assignment passivity-based control (IDA-PBC) method.",

      "abstract": "Port-Hamiltonian Systems (PHS) have a particular form that incorporates explicitly a function of the total energy in the system (energy function) and also other functions that describe structure of the system in terms of energy distribution. For PHS, the product of the input and output variables gives the rate of energy change. This type of systems have the property that under certain conditions on the energy function, the system is passive; and thus, stable. Therefore, if one can design a controller such that the closed-loop system retains—or takes—a PHS form, such closed-loop system will inherit the properties of passivity and stability. In this paper, the classical model of marine craft is put into a PHS form. It is shown that models used for positioning control do not have a PHS form due to a kinematic transformation, but a control design can be done such that the closed-loop system takes a PHS form. It is further shown how integral action can be added and how the PHS-form can be exploited to provide a procedure for control design that ensures passivity and thus stability.",

      "abstract": "In this paper we study two mixed (finite-dimensional and infinite dimensional) systems - a flexible beam on a moving cart and a fluid tank mounted on a moving cart. The cart is connected to ordinary dampers, which dissipate the energy. The ultimate objective of this work is to ensure that all the energy of the infinite dimensional system (due to any disturbances) flows into the dampers and gets dissipated. We show that this is possible under certain conditions and that boundary damping alone is sufficient to bring the composite system to rest. We adopt the port-Hamiltonian approach (van der Schaft and Maschke (2002)) for our analysis, which allows us to look at the composite plant as a power conserving interconnection of infinite and finite dimensional systems.",

Such errors are traditionally eliminated by adding a simple integrator. However, a simple integrator for nonlinear systems usually spoils the structure of the modeling framework. For passive systems it has been shown that passivity loses its global character. Here, integral type controllers are presented for standard nonlinear mechanical systems, based on the port-Hamiltonian and power-based modeling frameworks. Experimental results are given for a planar manipulator system.",

For the first controller is used the model system described as a Port-controlled Hamiltonian (PCH), which provides the system be described in a appropriate form for applying balancing of energy. For the second controller, it is used a model described by Brayton-Moser equations, which describes the system for implementing the balancing of power. Through these two methods, at the end, it is obtained the same controller known as PD with gravity compensation, which is implemented in the manipulator in study.",

      "abstract": "This paper considers the tracking controller design for a mechatronic handling system. The presented approach is mainly based on Port-Hamiltonian systems and it has the intension to combine a feedforward controller with a state feedback controller in order to achieve good tracking behavior as well as good disturbance rejection for the controlled plant. The controller design is separated into several tasks. At first a passivity-based tracking controller is derived for the mathematical model. The IDA-PBC design leads also to a Lyapunov function for the stability analysis of the closed loop. In addition the feedback controller is combined with a flatness-based feedforward control law and one has to derive a desired trajectory for a differentially flat system, where the fictive output and the regulated output do not match. Furthermore some given technical and optimality limitations should be considered within the trajectory planning problem. This approach avoids the solution of a boundary value problem as well as a real-time integration of the internal dynamics.",

      "abstract": "It is known that straightforward application of the classical Lagrangian and Hamiltonian formalism to systems with mass varying explicitly with position may lead to discrepancies in the formulation of the equations of motion. Systems with mass varying explicitly with position often arise from situations where the partitioning of a closed system of constant mass leads to open subsystems that exchange mass among themselves. One possible solution is to introduce additional non-conservative generalized forces that account for these effects. However, it remains unclear how to systematically interconnect the Lagrangian or Hamiltonian subsystems. In this paper, systems with mass varying explicitly with position and their properties are studied in the port-Hamiltonian modeling framework. The port-Hamiltonian formalism combines the classical Lagrangian and Hamiltonian approach with network modeling and is applicable to various engineering domains. One of the strong aspects of the port-Hamiltonian formalism is that power-preserving interconnections between port-Hamiltonian subsystems results in another port-Hamiltonian system with composite energy and interconnection structure. The motion of a heavy cable being deployed from a reel by the action of gravity is used as an example.",

Beside the intrinsic difficulties related to the large number of state variables, the finite element model is generally given in terms of a Dirac structure and is completely a-causal, which implies that the plant dynamics is not given in standard input-state-output form, but as a set of DAEs. Consequently, the classical energy-Casimir method has to be extended in order to deal with dynamical systems with constraints, usually appearing in the form of Lagrangian multipliers. The general methodology is illustrated with the help of an examples, i.e. an hinged-hinged Timoshenko beam with actuators at both sides.",

The controller design proceeds with different stages exploiting the benefit of having a preserved PCH structure of the system while in closed loop. An extension of ℒ2 disturbance attenuation control design under the assumption that the exogenous disturbance has a different input gain is also presented. Necessary and sufficient conditions to guaranty stability are stated. Robustness of the controller to parameter uncertainties is studied by assuming uncertain inertia and damping matrices. The design approach is applied to develop a PCH-based path tracking and ℒ2 disturbance attenuation controllers for Autonomous Underwater Vehicle (AUV). The simulation results demonstrate the performance of the designed controller in tracking both an horizontal plane path and a vertical plane path that passes through the singularity points. The simulation results indicate that the designed controller is robust enough to uncertainties in inertia and damping matrices. In addition, the extension of ℒ2 disturbance attenuation controller is able to attenuate the exogenous disturbance effect on AUV path tracking.",

For certain equilibria the definiteness requirements on the virtual energy of the port-Hamiltonian (pH) target system and the closed-loop dissipation matrix can not be satisfied simultaneously. In this contribution a modification of the pH target system is proposed, where particularly the total energy function is augmented by a cross term between coordinates and momenta. The approach stems from the fact that, although IDA-PBC may fail, unstable equilibria of underactuated mechanical systems are stabilized by linear state feedback, if the linearization is stabilizable. Then the solution of a Lyapunov equation for the linearized closed-loop system is not block diagonal, which gives rise to the proposed structure of the energy.",

      "abstract": "In this note the two well known nonlinear control design techniques Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) and Immersion and Invariance (I&I) are compared through the example of the so-called Acrobot underactuated mechanical system. Equivalences of both procedures become obvious from the corresponding immersion and matching equations. In particular, the coordinate change which renders the potential energy matching PDE in IDA-PBC an ordinary differential equation is used to define the immersion map in I&I. It is shown that the energy shaping part of the IDA-PBC controller makes the closed-loop system an interconnection of two lower-dimensional port-Hamiltonian (pH) systems in the on- and off-manifold coordinates. The effect of damping injection output feedback can be identified with dissipation in the off-manifold part of the interconnected system. Dissipation is propagated to the on-manifold part which results in asymptotic stability of the system's equilibrium. The analysis in the present work provides an interesting interpretation of the effect of the IDA-PBC control law using the I&I framework.",

      "abstract": "A class of quasi port Hamiltonian system expressing the first and second principle of thermodynamic as a structural property is defined, namely Irreversible PHS. The IPHS is defined by: a generating function that for physical systems corresponds to the total energy; a constant skew-symmetric structure matrix that represents the network structure of the system; a non-linear function that depends on the states and co-states and on the Poisson bracket of the generating function and some entropy function. For physical systems this Poisson bracket defines the thermodynamic driving force. The IPHS is completed with input and output ports. IPHS encompasses a large set of thermodynamic systems, including heat exchangers and chemical reactors. The non-isothermal CSTR is used to illustrate the formalism.",

      "abstract": "In this paper, a special class of damping model is introduced for second order dynamical systems. This class is built so as to leave the eigenfunctions invariant, while modifying the dynamics: for mechanical systems, well-known examples are the standard fluid and structural dampings. In the finite-dimensional case, the so-called Caughey series are a general extension of these standard damping models; the damping matrix can be expressed as a polynomial of a matrix, which depends on the mass and stiffness matrices. Damping is ensured whatever the eigenvalues of the conservative problem if and only if the polynomial is positive for positive scalar values. This can be recast in the port-Hamiltonian framework by introducing a port variable corresponding to internal energy dissipation (resistive element). Moreover, this formalism naturally allows to cope with systems including gyroscopic effects (gyrators). In the infinite-dimensional case, the previous polynomial class can be extended to rational functions and more general functions of operators (instead of matrices), once the appropriate functional framework has been defined. In this case, the resistive element is modelled by a given static operator, such as an elliptic PDE. These results are illustrated on several PDE examples: the Webster horn equation, the Bernoulli beam equation; the damping models under consideration are fluid, structural, rational and generalized fractional Laplacian or bi-Laplacian.",

These Dirac structures lay down a geometric framework for the formulation of Hamiltonian systems with a nonzero boundary energy flow. Simplicial triangulation of the underlaying manifold leads to the so-called simplicial Dirac structures, discrete analogues of Stokes-Dirac structures, and thus provides a natural framework for deriving finite-dimensional port-Hamiltonian systems that emulate their infinite-dimensional counterparts. The port-Hamiltonian systems defined with respect to Stokes-Dirac and simplicial Dirac structures exhibit gauge and a discrete gauge symmetry, respectively. In this paper, employing Poisson reduction we offer a unified technique for the symmetry reduction of a generalized canonical infinite-dimensional Dirac structure to the Poisson structure associated with Stokes-Dirac structures and of a fine-dimensional Dirac structure to simplicial Dirac structures. We demonstrate this Poisson scheme on a physical example of the vibrating string.",

It is shown how standard PI-control, regulating the storage variables irrespective of the inflows and outflows, corresponds to associating with every edge of the graph a controller state variable, yielding a closed-loop port-Hamiltonian system. Furthermore, it will be shown how regulation is proved by modifying the total Hamiltonian of the port-Hamiltonian system into a Lyapunov function based on the vector of constant inflows and outflows. Subsequently, the results are extended to the case that the input variables are constrained, leading to non-smooth Lyapunov functions.",

      "abstract": "The aim of this paper is to study a conservative wave equation coupled to a diffusion equation : this coupled system naturally arises in musical acoustics when viscous and thermal effects at the wall of the duct of a wind instrument are taken into account. The resulting equation, known as Webster-Lokshin model, has variable coefficients in space, and a fractional derivative in time. The port-Hamiltonian formalism proves adequate to reformulate this coupled system, and could enable another well-posedness analysis, using classical results from port-Hamiltonian systems theory. First, an equivalent formulation of fractional derivatives is obtained thanks to so-called diffusive representations: this is the reason why we first concentrate on rewriting these diffusive representations into the port-Hamiltonian formalism; two cases must be studied separately, the fractional integral operator as a low-pass filter, and the fractional derivative operator as a high-pass filter. Second, a standard finite-dimensional mechanical oscillator coupled to both types of dampings, either low-pass or high-pass, is studied as a coupled pHs. The more general PDE system of a wave equation coupled with the diffusion equation is then found to have the same structure as before, but in an appropriate infinite-dimensional setting, which is fully detailed.",

Once inputs and outputs of the distributed port-Hamiltonian system have been chosen to obtain a well-defined boundary control systems, conditions for the existence of Casimir functions in closed-loop and of the associated semigroup are given, together with a criterion to be used to check asymptotic stability. Casimir functions suggest how to select the controller Hamiltonian to introduce a minimum at the desired equilibrium, while stability is ensured if proper “pervasive” boundary damping is present. The methodology is illustrated with the help of a Timoshenko beam with full-actuation on one side.",

This leads to an energy–based description of the system which we later use for stability analysis. We use Park's state transformation to decouple the dynamics of other state variables from the dynamics of rotor angle, resulting in a quotient system admitting equilibria. We show that the solutions of this quotient system are bounded and provide closed form expression for the ultimate bound of these solutions. We will also give some preliminary results on stability analysis of these equilibria using energy shaping techniques.",

      "abstract": "This paper presents a thermodynamically consistent model of MSMA (Magnetic Shape Memory Alloys) under port Hamiltonian framework. It is based on previous works on MSMA proposed in (Gauthier et al., 2008; Calchand et al., 2011). The main difference lies in the choice of the state variables and manipulated thermodynamic forces. Furthermore in (Gauthier et al., 2008), subsequent experiments revealed a highly hysteretic behavior of these materials. Here, the simplified hysteretic behavior is incorporated into the port-hamiltonian model to obtain a finer and more precise model. Such modeling will allow the use of a wide range of energy based methods to design the associated control system. The paper ends with some extensions to more complex hysterestic phenomena by using Preisach like model. First ideas are proposed to extend the previous physical model to systems with internal hysteretic loops.",

      "abstract": "A prevailing trend in the stabilization of port-Hamiltonian systems is the assumption that the plant and the controller are both passive. In the standard approach of control by interconnection based on the generation of Casimir functions, this assumption leads to the dissipation obstacle, which essentially means that dissipation is admissible only on the coordinates of the closed-loop Hamiltonian that do not require shaping and thus severely restricts the scope of applications. In this contribution, we show that we can easily go beyond the dissipation obstacle by allowing the controller to have a negative semi-definite resistive structure, while guaranteeing stability of both the closed-loop and the controller.",

From the port-Hamiltonian description of the electrical circuits with memristors, a target dynamics is assigned to the matching equation proposed by the methodology known as Interconnection and Damping Assignment-Passivity-based Control. The inclusion of the memristor element extends the closed loop dynamics and it results in an extra term in the control algorithm that can be seen as a state-modulated gain. Two mechanical examples, in the form of a position control systems are included to show possible applications.",

We recall first how two port Hamiltonian systems coupled by an interface may be expressed as an port Hamiltonian systems augmented with two variables being the characteristic functions of of two spatial domains. Then we consider the case of a moving interface and show that it may be expressed as the preceeding port Hamiltonian system augmented with an input, being the velocity of the interface and define a conjugated output variable. We conclude by giving some definition of the passivity of interface relations coupling the external variables associated with the interface.",

A transformation of configuration variables and a potential field are used in a Port-Hamiltonian framework to design an energy-based controller. With the proposed controller, the geometric task associated with the manoeuvring problem depends on the desired potential energy (closed-loop) and the dynamic task depends on the total energy and damping. Therefore, guidance and motion control are addressed jointly, leading to model-energy-based trajectory generation.",

In these discrete schemes, variables are projected into appropriate bases in order to perform exact spatial differentiation. We show that some spectral and energetical properties are therefore preserved. A geometric (symplectic) collocation scheme using Lagrange polynomials is investigated. Numerical results show oscillations in the transient response in case of non homogeneous boundary conditions or sharp distributed control. A second symplectic spectral scheme using Bessel conjugated bases is then derived which allows a more accurate approximation of eigenfunctions and reduces the unwanted numerical oscillations. Finally, the proposed numerical integration of the control model is validated against experimental data from the tokamak Tore Supra.",

The control objective is to regulate the vehicle position to a manifold of dimension equal to the underactuation degree. We address the problem using Port-Hamiltonian theory, and reduce the associated matching PDEs to a set of algebraic equations using a kinematic identity. The resulting method for control design is constructive. The point within the manifold to which the position is regulated is determined by the action of the potential field and the geometry of the manifold. We illustrate the performance of the controller for an unmanned aerial vehicle with underactuation degree two–-a quadrotor helicopter.",

We show how the reference chemical potentials define a specific thermodynamical equilibrium, and we discuss the port-Hamiltonian representation of the formulation. This leads to the network interpretation as a number of energy-storing elements (corresponding to the chemical complexes), together with a nonlinear energy-dissipating relation corresponding to the reactions with associated conductances for the edges of the graph of complexes. The resulting system cannot be put into standard Brayton-Moser gradient system form, but it does allow a generalized gradient system representation with respect to the Gibbs' free energy.",

This paper focuses on the balance and closure equations in the material domain. First a kinetic theory point of view is adopted and transport equations are derived from the Boltzmann equation. Then material derivatives are introduced to derive macroscopic balance equations of the TMHD fluid model from these kinetic transport equations. Finally, the Gibbs-Duhem equation is used to compute the irreversible entropy source term and to define the interdomain ℛ - field of the model.",

      "abstract": "The frameworks of thermodynamic availability function and irreversible port Hamiltonian systems are used to derive passivity based control strategies for irreversible thermodynamic systems. An energy based availability function is defined using as generating function the internal energy. This is a variation with respect to previous works where the total entropy usually corresponds to the generating function. The specific structure of irreversible port-Hamiltonian systems then permits to elegantly derive stability conditions for open and closed thermodynamic systems. The results are illustrated on two classical thermodynamic examples: The heat exchanger and the continuous stirred tank reactor.",

We focus on IDA-PBC design for canonical port-Hamiltonian systems with separable energy being quadratic in momentum. For this class of systems, we define a discrete Hamiltonian dynamics that exactly satisfies a discrete energy balance. We then derive a discrete controller following the IDA-PBC procedure. The proposed methodology relies on an energy discretization scheme with suitable discrete conjugate port variables. The main result is illustrated on two examples: a nonlinear pendulum in order to compare with some simulation results of the literature, and the impact oscillator which requires robust discretization scheme.",

      "abstract": "The aim of this paper is to present a simple extension of the theory of linear, distributed, port-Hamiltonian systems to the nonlinear scenario. More precisely, an algebraic nonlinear skew-symmetric term has now been included in the PDE. It is then shown that the system can be equivalently written in terms of the scattering variables, and that these variables are strictly related with the Riemann invariants that appear in quasi-linear hyperbolic PDEs. For this class of PDEs, several results about the existence of solutions, and asymptotic stability of equilibria have already been presented in literature. Here, these results have been extended and applied within the port-Hamiltonian framework, where are suitable of a nice physical interpretation. The final scope is the boundary asymptotic stabilisation of a nonlinear flexible beam with a free-end, and full actuation on the other side.",

First, a coordinate transformation is applied to equivalently describe the original port-Hamiltonian system in a port-Hamiltonian form which has a constant mass-inertia matrix in the Hamiltonian. Then, we show how to derive an extended port-Hamiltonian system with structure preservation which can be used for force control purposes. Furthermore, we prove that the closed-loop system is asymptotically stable via a Lyapunov candidate function. Finally, experiments results are provided to show the advantages of the force control strategy in presence of external forces.",

The proposed controller is obtained combining a new full-information passivity-based controller with a new immersion and invariance observer. The resulting closed-loop system has, in some suitably defined coordinates, a port-Hamiltonian structure with a desired energy function and a uniformly positive definite damping matrix. In this way, global exponential tracking of position and velocity for all desired reference trajectories is ensured.",

We first clarify that passivity-based controls, damping assignment and potential shaping can be derived from a linear quadratic type optimal control problem. Next, we describe the limitation of passivity-based boundary controls and propose a practical usage of the methods in terms of discretization. Finally, we illustrate numerical results having a similar property to the strain feedback methods derived from semigroup theory for stabilizing and stiffness controlling flexible beams.",

In particular, we derive an energy-based model using the port-Hamiltonian theory and then design an active precession controller using passivity-based control interconnection and damping assignment. The design considers the possibility of having multiple gyro-stabiliser units, and the desired potential energy of the system (in closed loop) is chosen to behave like a barrier function, which allows us to enforce constraints on the precession angle of the gyros.",

      "abstract": "This paper reviews some recent results in motion control of marine vehicles using a technique called Interconnection and Damping Assignment Passivity-based Control (IDA-PBC). This approach to motion control exploits the fact that vehicle dynamics can be described in terms of energy storage, distribution, and dissipation, and that the stable equilibrium points of mechanical systems are those at which the potential energy attains a minima. The control forces are used to transform the closed-loop dynamics into a port-controlled Hamiltonian system with dissipation. This is achieved by shaping the energy-storing characteristics of the system, modifying its interconnection structure (how the energy is distributed), and injecting damping. The end result is that the closed-loop system presents a stable equilibrium (hopefully global) at the desired operating point. By forcing the closed-loop dynamics into a Hamiltonian form, the resulting total energy function of the system serves as a Lyapunov function that can be used to demonstrate stability. We consider the tracking and regulation of fully actuated unmanned underwater vehicles, its extension to under-actuated slender vehicles, and also manifold regulation of under-actuated surface vessels. The paper is concluded with an outlook on future research.",

      "abstract": "The scope of this paper is to show how to exploit the properties of the Stokes–Dirac structure in the development of energy-based boundary control laws for distributed port-Hamiltonian systems. Usually, stabilisation of non-zero equilibria has been achieved by shaping the open-loop Hamiltonian function by interconnecting a finite-dimensional port-Hamiltonian controller to the boundary of the distributed parameter system. The procedure is based on the presence of structural invariants, namely Casimir functions, in closed-loop, but this approach fails when a non-zero power flow from the controller is required at the equilibrium (dissipation obstacle). This paper illustrates that the class of stabilising controllers can be enlarged by relying on the parametrisation of the system dynamics provided by the image representation of the Stokes–Dirac structure, that is able to show the effects of the boundary inputs on the state evolution in a simple and effective way.",

Boundary controllability is studied in nonlinear and linearized cases. The controllability of the shallow water equations and the uniform controllability of the LBM are then investigated in the linearized case. It is shown that, using water levels/flows boundaries input variables in the LBM, there is a loss of controllability in the sequence of finite dimensional approximations when the order of the model increases. It is finally shown that we don't have this loss of controllability when the chosen input are boundary port-variables.",

In both cases we give an extension of the associated Hamiltonian operators to a Stokes-Dirac structure. Then we consider the Boussinesq equation and recall the two Hamiltonian representations either with respect to the canonical Hamiltonian operator associated with a system of two coupled conservation laws or with respect to a third order Hamiltonian operator. In this case we shall suggest a third Hamiltonian operator for which an extension to a Dirac structure is derived.",

This follows since the finite dimensional controller dissipates the energy flowing through the boundaries of the infinite dimensional system. The assumptions on the controller is that it is input strictly passive and that it is exponentially stable. The result is illustrated on the model of a boundary controlled DNA-manipulation process.",

Starting from the rigid body dynamics, a dynamical model of the wheeled robot is derived in the port-Hamiltonian framework. The formation control objective is achieved by interconnecting the robots using virtual couplings, which give a clear physical interpretation of the proposed solution. Simulation and experimental results are given, to illustrate the effectiveness of the approach.",

The considered hyperbolic systems of two conservation laws (with dissipation) are discretized in the spatial coordinate using an energy-based, structure preserving discretization scheme. The resulting finite-dimensional approximate state representation has a feedthrough term which allows to directly express the differential equation for the inverse dynamics. The inverse system needs to be solved in order to determine the control inputs for given desired output trajectories. For non-collocated pairs of boundary in- and outputs the magnitude of dissipation determines whether the inverse discretized models are stable or not. In the unstable case, the problem at hand can be attacked with classical approaches for the dynamic inversion of non-minimum phase systems.",

      "abstract": "We consider the problems of frequency stability, voltage stability and power sharing in droop–controlled inverter–based microgrids with meshed topologies and dominantly inductive power lines. Assuming that the conductances in the microgrid can be neglected, a port–Hamiltonian description of a droop–controlled microgrid is derived. The model is used to establish sufficient conditions for local stability. Furthermore, we propose a condition for the controller parameters such that a desired steady–state active power distribution is achieved. The robustness of the stability condition with respect to the presence of conductances is analyzed via a simulation example based on the CIGRE benchmark medium voltage distribution network.",

      "abstract": "The aim of this paper is to apply new results on the boundary stabilisation via energy-shaping of distributed port-Hamiltonian systems to a nonlinear PDE, i.e. a slightly simplified formulation of the shallow water equation. Usually, stabilisation of non-zero equilibria via energy-balancing has been achieved by looking at, or generating, a set of structural invariants (Casimir functions), in closed-loop. This approach is not successful in case of the shallow water equation because at the equilibrium the regulator is supposed to supply an infinite amount of energy (dissipation obstacle). In this paper, it is shown how to construct a controller that behaves as a state-modulated boundary source and that asymptotically stabilises the desired equilibrium. The proposed approach relies on a parametrisation of the dynamics provided by the image representation of the Dirac structure associated to the distributed port-Hamiltonian system. In this way, the effects of the boundary inputs on the state evolution are explicitly shown, and as a consequence the boundary control action that maps the open-loop system into a target one characterised by the desired stability properties, i.e. by a “new” Hamiltonian with an isolated minimum at the equilibrium, is determined.",

Constrained linear port Hamiltonian systems are first written in a canonical descriptor form such that the Hamiltonian structure is preserved. The computations of the controllability and observability Gramians are then used to derive the balanced port Hamiltonian representation of the system. The method of flow constraint is applied to reduce the system. Finally, numerical simulations for the reduction of a micro mechanical actuator model is given to illustrate the effectiveness of the proposed method.",

We first extend existing results on asymptotic stability of linear infinite dimensional systems controlled at their boundary to the case of stable Port Hamiltonian controllers including some physical constraints as clamping. Then the relation between structural invariants, namely Casimir functions, and the controller structure is computed. The Casimirs are employed in the selection of the controllers Hamiltonian to shape the total energy function of the closed loop system and introduce a minimum in the desired equilibrium configuration. The approach is illustrated on the model of a micro manipulation process with partial-actuation on one side of the spatial domain.",

      "abstract": "In this article, the problem of hybrid optimal control for DC-DC power converters is treated. The designed control is of type bang-bang established from Pontryagin's maximum principle. The control is a state feedback and it is determined using an energy based minimization criterion derived from the power balance of Port-Hamiltonian systems. The developed control has the advantage to be easy to design and simple to implement in real time applications. The proposed control is applied to a SEPIC converter and validated in simulation and experimentation.",

      "abstract": "Irreversible port Hamiltonian systems are a class of pseudo Hamiltonian systems that expresses both the conservation of energy and the irreversible entropy production as a structural property. These systems encompass a large class of irreversible themordynamic systems, such as heat exchangers and chemical reactors, and also multi-energy systems such as coupled mechanic-thermodynamic systems. In recent work the irreversible port-Hamiltonian formulation has been used to derive a closed-loop stability condition using an energy based availability function, generated by the internal energy, as Lyapunov function. This paper presents an important extension of the previous results: the system theoretic interpretation of the stability condition in terms of conjugated inputs and outputs and the formulation of the control as an interconnection and damping assignment - passivity based control problem. A constructive method to derive the stabilizing control law is proposed and the formalism is illustrated on a general CSTR example.",

      "abstract": "In this article we study the possibilities of recovering the structure of port-Hamiltonian systems starting from “unlabelled” ordinary differential equations describing mechanical systems. The algorithm we suggest solves the problem in two phases. It starts by constructing the connectivity structure of the system using machine learning methods – producing thus a graph of interconnected subsystems. Then this graph is enhanced by recovering the Hamiltonian structure of each subsystem as well as the corresponding ports. This second phase relies heavily on results from symplectic and Poisson geometry that we briefly sketch. And the precise solutions can be constructed using methods of computer algebra and symbolic computations. The algorithm permits to extend the port-Hamiltonian formalism to generic ordinary differential equations, hence introducing eventually a new concept of normal forms of ODEs.",

      "abstract": "This paper addresses the problem of sinusoidal voltage generation in linear loads using a voltage source inverter (VSI). The port-Hamiltonian structure in open-loop is used to design a passivity-based controller with proportional-integral gains (PI-PBC) in order to develop the control strategy. The main advantage of using passivity-based controllers corresponds to the possibility of guaranteeing asymptotic stability by transforming the trajectory tracking problem into a regulation control one. In addition to the PI-PBC, a linear load estimator is employed based on an integral formulation to determine the value of the equivalent conductance in the load, which reduces the number of current sensors. Numerical validations demonstrate that the sinusoidal voltage provided by the VSI to the load has a tracking error lower than $1~\\%$, with harmonic distortions lower than $2.6~\\%$, both for voltage and currents in the load. All the simulations were conducted in MATLAB/Simulink using the SimPowerSystems library version 2017a.",

      "abstract": "We discuss structure-preserving model order reduction for port-Hamiltonian systems based on a nonlinear approximation ansatz which is linear with respect to a part of the state variables of the reduced-order model. In recent years, such nonlinear approximation ansatzes have gained more and more attention especially due to their effectiveness in the context of model reduction for transport-dominated systems which are challenging for classical linear model reduction techniques. We demonstrate that port-Hamiltonian reduced-order models can often be obtained by a residual minimization approach where a suitable weighted norm is used for the residual. Moreover, we discuss sufficient conditions for the resulting reduced-order models to be stable. Finally, the methodology is illustrated by means of two transport-dominated numerical test cases, where the ansatz functions are determined based on snapshot data of the full-order state.",

However, in active training modes, control instability may be induced by the nonlinear and time-varying characteristics of muscle fatigue, increasing the risks of physical human-robot interaction and ultimately limiting rehabilitation outcomes.MethodsA novel control strategy within the port-Hamiltonian framework, incorporating a dynamic muscle fatigue model. Fatigue levels were assessed in real time using surface electromyography (sEMG) signals and mapped to damping parameters in joint space, enabling the port-based modeling of fatigue-related energy dissipation. A hierarchical control architecture was constructed, consisting of outer-loop admittance control and inner-loop energy shaping.ResultsTheoretical analysis confirmed that the closed-loop passivity of the system was preserved and stability was ensured. Experimental validation further showed that, compared to fixed damping parameters, the proposed fatigue compensation approach reduced muscle fatigue accumulation by 45% and increased training duration by 40%.DiscussionThe proposed fatigue-adaptive control framework was shown to enhance the safety, effectiveness, and physiological adaptability of rehabilitation training. The integration of real-time sEMG feedback and port-Hamiltonian modeling offers a promising solution for personalized robotic rehabilitation.",

      "abstract": "For frequency and voltage stability control of grid-forming converters in high-power electronic scenarios, this paper proposes a grid-forming converter grid-connection stability control strategy based on passive control and deep reinforcement learning. Firstly, the virtual synchronous generator (VSG) is written in the port-Hamiltonian form to clarify the interconnection and dissipative structure, and the achievable passive control law is obtained by energy shaping and damping injection. Then, DDPG is introduced to adjust the damping parameters online, so that the control has adaptive ability under multiple working conditions, and the closed-loop system is proved to be asymptotically stable based on Lyapunov function. Finally, the simulation example analysis is carried out. In the simulation of power mutation, voltage imbalance, short-circuit fault and load change, this method significantly reduces the overshoot and adjustment time compared with VSG-PI and fixed parameter PBC, and improves the steady-state error and energy dissipation rate. The simulation results verify the effectiveness of the combination of physical consistency and strategy adaptation.",

      "abstract": "Time-domain simulation of woodwind instruments typically involves the development of separate discrete-time sub-models for the excitation mechanism and the resonator. These components have largely been modeled via digital waveguide or finite-difference time-domain (FDTD) methods. We present a separate approach based on the modular and energy-based port-Hamiltonian system (PHS) framework. We recast the three main components of a woodwind instrument—the single-reed, the bore, and the tonehole—as PHS models and incorporate novel elements in each derivation. In the beating reed model, we make use of recent work on energy quadratization to formulate a linearly implicit scheme of the nonlinear Hunt-Crossley contact force coupled to a nonlinear Bernoulli flow. In the horn model, we discretize a distributed PHS representing the horn equation with a generalized symplectic Störmer-Verlet scheme, verifying previously proposed FDTD schemes. In the tonehole model, we propose a new low-frequency model of the tonehole and model note transitions with a switching PHS. The benefit of describing each element as a PHS is demonstrated by the ability to interconnect all sub-models in a modular and energy-conserving manner to simulate a complete instrument. Simulations are performed on a test instrument and the numerical stability of the overall scheme is demonstrated.",

      "abstract": "The vocal apparatus is a biophysical dynamic system capable of self-oscillation, which involves fluid–structure interactions and human control. This study on the sound synthesis of voiced sounds presents a physical quasi-1D model of the vocal apparatus in the port-Hamiltonian framework and its validation through numerical experiments. The modelling ensures balanced power exchanges between fluid, tissues, and human control. Fluid is represented in the larynx and in the vocal tract using a unified 1D PDE handling transverse geometry variations. A regularisation procedure is introduced to mitigate the numerically stiff behaviour of the model observed at channel closure. Vocal folds and vocal tract walls are represented by lumped element models as well as the radiation load at the lips, which consists of a first-order high-pass filter. Spatial discretisation of the fluid model and temporal discretisation of the full system are made using structure-preserving methods to ensure energy consistency (passivity). The second part of this paper focuses on numerical experiments to progressively characterise the model and assess its validity. These experiments begin with frequency response analysis of a static vocal tract under quasi-linear conditions followed by simulations of vowel transitions (diphthongs) under forced excitation. Next, self-oscillation studies are conducted on an isolated larynx where contact parameters are adjusted. Lastly, full simulations of the self-oscillating vocal apparatus with co-articulation, representing a voice synthesizer capable of articulating vowels, are presented. The dynamics are also analysed in terms of energy transfer and passivity. Finally, these results are discussed to establish a basis for future model refinements and to identify directions for enhancing the accuracy and realism of vocal synthesis.",

      "abstract": "In this paper, the infinite-dimensional port-Hamiltonian modelling and control problem of a flexible beam actuated using ionic polymer metal composite (IPMC) actuators is investigated. The port-Hamiltonian framework is used to propose an interconnected control model of the mechanical flexible beam and the IPMC actuator. The mechanical flexible dynamic is modelled as a Timoshenko beam, and the electric dynamics of the IPMCs are considered in the model. Furthermore, a passivity-based control-strategy is used to obtain the desired configuration of the proposed interconnected system, and the closed-loop stability is analyzed using the early lumped approach. Lastly, numerical simulations and experimental results are presented to validate the proposed model and the effectiveness of the proposed control law.",

      "abstract": "Electromechanical actuators (EMAs) are increasingly used in aerospace servo actuation because of their compact structure, high power density, and convenient integration with electric flight-control systems. However, load-side aerodynamic torque, friction, parameter perturbations, and unmodeled transmission effects enter the EMA dynamics through a channel different from the motor-current input, which leads to a mismatched disturbance rejection problem. This paper develops a feedback-linearization-assisted observer-based interconnection and damping assignment passivity-based control (IDA-PBC) method for EMA trajectory tracking. A fourth-order input–output feedback-linearized normal-coordinate model is first derived, through which the original load-side mismatched disturbance is transformed into a matched term acting on the highest-order channel. An extended state observer is then constructed to estimate the transformed disturbance. Based on the observer output, a desired Hamiltonian function is generated from a Lyapunov equation, and the interconnection and damping matrices are explicitly assigned so that the closed-loop tracking-error dynamics admit a dissipative port-Hamiltonian representation. A composite Lyapunov analysis proves closed-loop exponential stability under the assumption of slowly varying disturbance. The resulting framework combines the disturbance-channel-reshaping capability of feedback linearization with the energy-shaping interpretation of IDA-PBC, providing a systematic controller design for high-precision EMA servo systems subject to load-side disturbances.",

      "abstract": "Water-pumped storage systems have become an ideal alternative to regulate the intermittent power delivered by renewable energy sources. For small-scale operations, a type of centrifugal pump coupled to asynchronous machines represents an adequate solution due to their techno-economic feasibility in addition to their ability to operate as reversible systems. This work provides a novel port-Hamiltonian modelling approach to an integrated reversible hydropump–turbine system, that can be switched from motor pump to turbine-generator by employing a conventional hydraulic switch. Our modelling strategy provides a clear physical interpretation of the energy flow from the mechanical to electrical domains. Then, the model was built with multi-domain storing and dissipating elements and the interconnection of well-defined input–output port pairs. The system’s internal energy, i.e., Hamiltonian function, can be exploited for energy-shaping control strategies. The performance of our modelling approach is validated via numerical simulations.",

Indeed, the increasing developments in recent years allow finding better control and coupling strategies. This work aimed to apply such an approach to Naghdi–Reissner’s five-kinematic-field shell model in linear elasticity, while including often-neglected higher-order intrinsic geometric coupling effects, therefore preparing the theoretical background required for the coupling (or interconnection) with an acoustic fluid model and the different types of interactions that can arise among them. The model derived thusly can be used for controller design in a wide variety of applications such as inflatable space structures, launcher tank vibration damping, payload vibration protection using smart materials, and many other related applications.",

      "abstract": "Satellite formation flying technology currently represents a focal point in space mission research. Traditional spacecraft payload performance and lifespan are often constrained by propellant limitations. Electromagnetic Formation Flying (EMFF), a propellant-free formation flying technique, has garnered widespread attention. Its inherent strong nonlinearity and coupling present challenges for high-precision control within EMFF. This paper presents the relative motion dynamics of a two-satellite EMFF in the port-Hamiltonian framework and constructs an accurate nonlinear model of the dynamics. Utilizing the concept of Interconnection and Damping Assignment and nonlinear disturbance observer, a composite disturbance-rejection passivity-based controller is designed, offering a method for controlling the magnetic dipole strength of formation satellites. Finally, numerical simulations are conducted to demonstrate the viability of the proposed dynamics model and control strategy.",

      "abstract": "This paper presents a controller design to track speed, position, and torque trajectories for a permanent magnet synchronous motor (PMSM). This scheme is based on the interconnection and damping assignment passivity-based control (IDA-PBC) technique recently proposed to solve the tracking control problem for mechanical underactuated systems. The proposed approach regulates the dynamics of the tracking system error at the origin, assuming the realizable trajectories preserve the motor’s port-controlled Hamiltonian structure. The importance of the contribution is two-fold: First, from the theoretical perspective, the trajectory tracking control problem is solved with proved stability properties, a topic that has not been deeply studied with the IDA-PBC methodology design. Second, from the practical point of view, the proposed control scheme exhibits a simple structure for practical implementation and strong robustness properties with respect to parametric uncertainties. The contribution is evaluated under both numerical and experimental environments considering a speed profile that demands the achievement of high dynamic performances.",

      "abstract": "We present a method that generates passive-guaranteed stable simulations of analog audio circuits from electronic schematics for real-time issues. On one hand, this method is based on a continuous-time power-balanced state-space representation structured into its energy-storing parts, dissipative parts, and external sources. On the other hand, a numerical scheme is especially designed to preserve this structure and the power balance. These state-space structures define the class of port-Hamiltonian systems. The derivation of this structured system associated with the electronic circuit is achieved by an automated analysis of the interconnection network combined with a dictionary of models for each elementary component. The numerical scheme is based on the combination of finite differences applied on the state (with respect to the time variable) and on the total energy (with respect to the state). This combination provides a discrete-time version of the power balance. This set of algorithms is valid for both the linear and nonlinear case. Finally, three applications of increasing complexities are given: a diode clipper, a common-emitter bipolar-junction transistor amplifier, and a wah pedal. The results are compared to offline simulations obtained from a popular circuit simulator.",

      "abstract": "Mechanical ventilation is a life-saving treatment for critically ill patients who are struggling to breathe independently due to injury or disease. Globally, per year, there has always been a large number of individuals who have required mechanical ventilation. The COVID-19 pandemic brought to light the significance of mechanical ventilation, which played a significant role in sustaining COVID-19-infected critically ill patients who could not breathe on their own. The pandemic drew the attention of the world to the shortage of ventilators globally. Some of the challenges to providing an adequate number of ventilators include: increased demand for ventilators, supply chain disruptions, manufacturing constraints, distribution inequalities, financial constraints, maintenance and logistics difficulties, training and expertise shortages, and the lack of design and development of affordable mechanical ventilators that satisfy the stipulated requirements. This research work presents the formulation of a detailed Port–Hamiltonian model of a mechanical ventilator integrated with the human respiratory system. The interconnection and coupling conditions for the various subsystems within the mechanical ventilator and the coupling between the mechanical ventilator and the human respiratory system are also presented. Structure-preserving discretization is provided alongside numerical simulations and results. The obtained results are found to be comparable to results presented in the literature. Future work will include the design of suitable controllers for the system.",

      "abstract": "Wind–solar power generating and hybrid battery-supercapacitor energy storage complex is used for autonomous power supply of consumers in remote areas. This work uses passivity-based control (PBC) for this complex in accordance with the accepted energy management strategy (EMS). Structural and parametric synthesis of the overall PBC system was carried out, which was accompanied by a significant amount of research. In order to simplify this synthesis, a structural decomposition of the overall dynamic system of the object presented in the form of a port-Hamiltonian system, which was described by a system of differential equations of the seventh order, into three subsystems was applied. These subsystems are a wind turbine, a PV plant, and a hybrid battery-supercapacitor system. For each of the subsystems, it is quite simple to synthesize the control influence formers according to the interconnections and damping assignment (IDA) method of PBC, which locally performs the tasks set by the EMS. The results obtained by computer simulation of the overall and decomposed systems demonstrate the effectiveness of this approach in simplifying synthesis and debugging procedures of complex multi-physical systems.",

      "abstract": "The dynamics of port-Hamiltonian systems is based on energy balance principles (the first law of thermodynamics) embedded in the structure of the model. However, when dealing with thermodynamic subsystems, the second law (entropy production) should also be explicitly taken into account. Several frameworks were developed as extensions to the thermodynamic domain of port-Hamiltonian systems. In our work, we study three of them, namely irreversible port-Hamiltonian systems, entropy-based generalized Hamiltonian systems, and entropy-production-metric-based port-Hamiltonian systems, which represent alternative approaches of selecting the state variables, the storage function, simplicity of physical interpretation, etc. On the example of a simplified lumped-parameter model of a heat exchanger, we study the frameworks in terms of their implementability for an IDA-PBC-like control and the simplicity of using these frameworks for practitioners already familiar with the port-Hamiltonian systems. The comparative study demonstrated the possibility of using each of these approaches to derive IDA-PBC-like thermodynamically consistent control and provided insight into the applicability of each framework for the modeling and control of multiphysics systems with thermodynamic subsystems.",

      "abstract": "<jats:p>Since the 1970s, contact geometry has been recognized as an appropriate framework for the geometric formulation of thermodynamic systems, and in particular their state properties. More recently it has been shown how the symplectization of contact manifolds provides a new vantage point; enabling, among other things, to switch easily between the energy and entropy representations of a thermodynamic system. In the present paper, this is continued towards the global geometric definition of a degenerate Riemannian metric on the homogeneous Lagrangian submanifold describing the state properties, which is overarching the locally-defined metrics of Weinhold and Ruppeiner. Next, a geometric formulation is given of non-equilibrium thermodynamic processes, in terms of Hamiltonian dynamics defined by Hamiltonian functions that are homogeneous of degree one in the co-extensive variables and zero on the homogeneous Lagrangian submanifold. The correspondence between objects in contact geometry and their homogeneous counterparts in symplectic geometry, is extended to the definition of port-thermodynamic systems and the formulation of interconnection ports. The resulting geometric framework is illustrated on a number of simple examples, already indicating its potential for analysis and control.</jats:p>",

      "abstract": "In this study, the design of an adaptive terminal sliding mode controller for the stabilization of port Hamiltonian chaotic systems with hidden attractors is proposed. This study begins with the design methodology of a chaotic oscillator with a hidden attractor implementing the topological framework for its respective design. With this technique it is possible to design a 2-D chaotic oscillator, which is then converted into port-Hamiltonia to track and analyze these models for the stabilization of the hidden chaotic attractors created by this analysis. Adaptive terminal sliding mode controllers (ATSMC) are built when a Hamiltonian system has a chaotic behavior and a hidden attractor is detected. A Lyapunov approach is used to formulate the adaptive device controller by creating a control law and the adaptive law, which are used online to make the system states stable while at the same time suppressing its chaotic behavior. The empirical tests obtaining the discussion and conclusions of this thesis should verify the theoretical findings.",

A new conservative memristor-based chaotic system is built by embedding this three-terminal memristor into a newly proposed four-dimensional (4D) Euler equation. The generalized Hamiltonian energy function has been given, and it is composed of conservative and non-conservative parts of the Hamiltonian. The Hamiltonian of the Euler equation remains constant, while the three-terminal memristor’s Hamiltonian is mutative, causing non-conservation in energy. Through proof, only centers or saddles equilibria exist, which meets the definition of the conservative system. A non-Hamiltonian conservative chaotic system is proposed. The Hamiltonian of the conservative part determines whether the system can produce chaos or not. The non-conservative part affects the dynamic of the system based on the conservative part. The chaotic and quasiperiodic orbits are generated when the system has different Hamiltonian levels. Lyapunov exponent (LE), Poincaré map, bifurcation and Hamiltonian diagrams are used to analyze the dynamical behavior of the non-Hamiltonian conservative chaotic system. The frequency and initial values of the system have an extensive variable range. Through the mechanism adjustment, instead of trial-and-error, the maximum LE of the system can even reach an incredible value of 963. An analog circuit is implemented to verify the existence of the non-Hamiltonian conservative chaotic system, which overcomes the challenge that a little bias will lead to the disappearance of conservative chaos.",

      "abstract": "A comprehensive overview of the irreversible port-Hamiltonian system’s formulation for finite and infinite dimensional systems defined on 1D spatial domains is provided in a unified manner. The irreversible port-Hamiltonian system formulation shows the extension of classical port-Hamiltonian system formulations to cope with irreversible thermodynamic systems for finite and infinite dimensional systems. This is achieved by including, in an explicit manner, the coupling between irreversible mechanical and thermal phenomena with the thermal domain as an energy-preserving and entropy-increasing operator. Similarly to Hamiltonian systems, this operator is skew-symmetric, guaranteeing energy conservation. To distinguish from Hamiltonian systems, the operator depends on co-state variables and is, hence, a nonlinear-function in the gradient of the total energy. This is what allows encoding the second law as a structural property of irreversible port-Hamiltonian systems. The formalism encompasses coupled thermo-mechanical systems and purely reversible or conservative systems as a particular case. This appears clearly when splitting the state space such that the entropy coordinate is separated from other state variables. Several examples have been used to illustrate the formalism, both for finite and infinite dimensional systems, and a discussion on ongoing and future studies is provided.",

Then, this research demonstrates how the factorization of the irreversible entropy production leads to quasi-Hamiltonian formulations, and how this can be used for stability analysis. The Liouville geometry approach to contact geometry is summarized, and how this leads to the definition of port-thermodynamic systems is discussed. This notion is utilized for control by interconnection of thermodynamic systems.",

      "abstract": "In this paper, we discuss the geometric structure, i.e., Dirac structure, underlying port-Hamiltonian systems. The paper has a tutorial character, and thus it contains questions/exercises. We start with the general definition of a Dirac structure and show that on finite-dimensional spaces, there is a simple matrix characterization. By simple examples, we show that, even in the finite-dimensional case, a Dirac structure does not guarantee the existence of solutions for an associated ordinary differential or difference equation. For associated partial differential equations, i.e., on an infinite-dimensional Dirac structure, the existence problem becomes even more challenging. We show that the spaces have to be chosen with care, but when we have shown the existence of solutions, then the Dirac structure will give us the desired properties, such as conservation of energy. The Dirac structure also implies that the associated transfer function has nice properties.",

      "abstract": "Real-world autonomous agents learn under nonstationarity, safety constraints, and finite energetic budgets. We develop a framework for perennial learning—agents that continuously refine their models while provably controlling the cost of forgetting—by unifying three classical pillars: Kolmogorov complexity, which equates scientific discovery with algorithmic compression; Landauer’s principle, which assigns a minimal thermodynamic cost of kBTln2 per erased bit to every irreversible model update; and port-Hamiltonian (PH) dynamics, whose (J−R)∇H decomposition separates zero-cost reversible inference from costly irreversible forgetting by construction. The Maxwell demon analogy is formalized: each learning episode is a Szilard cycle in which information acquisition, belief transport, and memory erasure must balance thermodynamically. The information-distance framework, comprising the normalized information distance (NID) and normalized compression distance (NCD), provides a computable geometry for measuring learning progress and guiding curriculum design. We separate theideal uncomputable regularizer based on prefix complexity from the practical compressor/MDL (minimum description length) surrogate that appears in optimization and prove a calibration lemma linking the two under a mild uniform-accuracy assumption. Under explicit regularity, compact-sublevel, and non-energy-extracting assumptions, we prove a passivity speed limit for curriculum-induced contractions of the effective feasible set. Under local asymptotic normality, we reprove that Fisher information is a local posterior codelength proxy rather than an exact theorem about algorithmic entropy. A conditional sequential information-budget proposition shows that the per-stage sample requirement scales as O˜(Δkt/λ⋆), where Δkt is the number of materially changed model coordinates (not the total model complexity kt); the k3→Δk improvement is conditional on a warm-start assumption and a chosen cold-start baseline. A double-integrator running example with a moving obstacle illustrates the architecture.",

      "abstract": "This paper aims to describe a synthesis procedure for discrete-time, energy-based regulators for continuous-time port-Hamiltonian systems. The methodology consists of three steps. The first deals with the definition of a discrete-time approximation of the plant, which is subsequently employed in the development of the control law. The discrete-time model is obtained from the continuous-time dynamics by replacing the gradient of the Hamiltonian function with a discrete gradient. In this way, passivity, with the energy as storage function, is preserved, although the resulting state equation is in implicit form. The second step concerns the control synthesis and extends the continuous-time energy-shaping plus damping injection design technique to the proposed class of discrete-time port-Hamiltonian systems. Finally, the last step addresses the interconnection between the digital controller and the continuous-time plant. The coupling is implemented via a zero-order hold and relies on the solution of an optimization problem that determines the “best” and “minimal” correction to be applied to the nominal control action in order to achieve the same performance as that obtained when the regulator is connected in closed loop with the discrete-time model of the plant. This is the reference scenario used to develop and tune the control law. The complete procedure (time discretisation, control design, and coupling implementation) is illustrated through an example.",

      "abstract": "Battery energy storage systems (BESSs) with proportional-integral (PI) control methods have been widely studied in microgrids (MGs). However, the performance of PI control methods might be unsatisfactory for BESSs due to the nonlinear characteristics of the system. To overcome this problem, an energy-based (EB) control method is applied to control the converter of a BESS in this study. The EB method is a robust nonlinear control method based on passivity theory with good performance in both transient and steady states. The detailed design process of the EB method in the BESS by adopting an interconnection and damping assignment (IDA) strategy is described. The design process comprises three steps: the construction of the port-controlled Hamiltonian model, the determination of the equilibrium point and the solution of the undetermined matrix. In addition, integral action is combined to eliminate the steady state error generated by the model mismatch. To establish the correctness and validity of the proposed method, we implement several case simulation studies based on a test MG system and compare the control performance of the EB and PI methods carefully. The case simulation results demonstrate that the EB method has better tracking and anti-disturbance performance compared with the classic PI method. Moreover, the proposed EB method shows stronger robustness to the uncertainty of system parameters.",

      "abstract": "According to the theory of passivity-based control (PBC), this paper establishes a port-controlled Hamiltonian system with dissipation (PCHD) model for a doubly fed induction generator (DFIG) system under unbalanced grid voltage conditions and proposes a method of interconnection and damping assignment passivity-based control (IDA-PBC) of the system under such conditions. By using this method, the rotor-side converter and grid-side converter can be controlled simultaneously in order to improve fault ride-through capability of the DFIG system. Simulation results indicate that this IDA-PBC strategy effectively suppresses fluctuations of output current and power in the DFIG system during unbalanced grid voltage sag/swell, enhances dynamic performance, and improves the robustness of the system.",

      "abstract": "This paper presents a novel idea based on the Port-Hamiltonian and cascade system to control the electric vehicle-to-grid (V2G) system. Based on the proposed method, the relationship between the converter plant gain and the moment of inertia of generator that has been established is effective for decoupled control of the V2G system. It is well known that the existing methods apply the H ∞ control and PSO method to enumerate and choose the value of converter plant gain from the region decided by the state of charge. Since an explicit form of converter plant gain is obtain in this paper, the proposed method that is unnecessary to repeat the above existing details effectively reduces the calculated amount of converter plant gain. Finally, the simulations demonstrate the validity and advantage of the proposed method.",

Firstly, the water surface three-degree-of-freedom ship models are transformed into port-controlled Hamiltonian (PCH) models. Using a single output feedback controller, the two PCH systems are combined to generate an enhanced PCH system based on Hamiltonian structural attributes. Then, considering the situation with both external interference and structural parameter perturbation in the systems, an adaptive robust output feedback controller is designed to stabilize the two systems simultaneously. Finally, the effectiveness of the controller proposed in this paper is illustrated by a simulation example.",

By combining robot and motor model, the complete model of the robot driving system is established. The single-loop Feedback Linearization (FL) controller and Port-Controlled Hamiltonian (PCH) controller based on the complete model are derived to ensure the rapidity and stability of the system respectively. A smooth-switching function based on position error is designed. It can ensure the smooth-switching between two controllers and avoid the instability caused by switch-switching. The proposed algorithm can make the robot system have good dynamic and steady performance. Simulation and experiment results demonstrate the effectiveness of the smooth-switch control strategy.",

      "abstract": "DC-DC converters with constant power loads are mostly used in DC microgrids. Negative impedance and large disturbances of constant power loads may lead to the instability of DC-DC converters. To address this issue, a nonlinear control strategy consisting of an improved passivity-based controller and nonlinear power observer is proposed in this paper. First, an improved passivity-based controller is designed based on the port-controlled Hamiltonian with dissipation model. By proper damping and interconnection injecting, the fast dynamic response of output voltage and stability of the DC-DC converter is achieved. Second, the constant power load is observed by a nonlinear power observer, which is adopted to estimate the power variation of the constant power load within a small settling time and improve the adaptability of the DC-DC converter under power disturbance. Finally, the simulation and experimental results are presented, which illustrate the proposed control strategy not only ensures the stability of the DC-DC converter under large disturbances, but also can track the desired operating point with low voltage overshoot in no more than 10 milliseconds.",

      "abstract": "This paper discusses energy behaviors in hydraulic cylinder dynamics, which are important for model-based control of agriculture scale excavators. First, we review hydraulic cylinder dynamics and update our physical parameter identification method to agriculture scale experimental excavators in order to construct a nominal numerical simulator. Second, we analyze the energy behaviors from the port-Hamiltonian point of view which provides many links to model-based control at laboratory scale at least. At agriculture scale, even though the nominal numerical simulator is much simpler than an experimental excavator, the analytical, experimental, and numerical energy behaviors are very close to each other. This implies that the port-Hamiltonian point of view will be applicable in agriculture scale against modeling errors.",

      "abstract": "In this article, we propose a mathematical model using the port-Hamiltonian formalism for a satellite’s three-axis attitude system comprising fluid rings. Fluid rings are an alternative to reaction wheels used for the same purpose, since, for the same mass, they can exert a greater torque than a reaction wheel as the fluid can circulate the periphery of the satellite. The port-Hamiltonian representation lays the foundation for a posterior controller that is feasible, stable, and robust based on the interconnection of the system to energy shaping and/or damping injection components, and by adding energy routing controllers. The torques exerted by the fluid rings are modeled using linear regression analysis on the experimental data got from a prototype of a fluid ring. Since the dynamics of turbulent flows is complex, the torques obtained by the prototype lead to a simpler first approach, leaving its uncertainties to a controller. Thus, the attitude system model could be tested in a future prototype before considering a spatial environment.",

      "abstract": "The operational stability and performance of dual active bridge (DAB) converters are dictated by an intricate coupling of electrical, magnetic, and thermal dynamics. Conventional modeling paradigms fail to capture these interactions, creating a critical gap between design predictions and real performance. A unified Port-Hamiltonian model (PHM) is developed, embedding nonlinear, temperature-dependent material physics within a single, energy-conserving structure. Derived from first principles and experimentally validated, the model reproduces high-frequency dynamics, including saturation-driven current spikes, with superior fidelity. The energy-based structure systematically exposes the converter’s stability boundaries, revealing not only thermal runaway limits but also previously obscured electro-thermal oscillatory modes. The resulting framework provides a rigorous foundation for the predictive co-design of magnetics, thermal management, and control, enabling guaranteed stability and optimized performance across the full operational envelope.",

The paper proposes a transition from “causality” to “purposefulness” in nature, which is called port-Hamiltonian thermodynamics. It is unclear whether classical thermodynamics can be incorporated into the formalism of port-Hamiltonian field theory, and it is likely that thermodynamics will need to be expanded or even completely reformulated. The main goal is to satisfy the First and Second Laws of Thermodynamics a priori.",

A passivity-based sliding mode controller is designed, integrating adaptive disturbance estimation and an RBFNN-based uncertainty estimator. Stability is rigorously proven, and simulations confirm superior tracking performance, strong disturbance rejection, and accurate uncertainty estimation.",

      "abstract": "Accurately predicting the long-term behavior of complex dynamical systems is a central challenge for safety-critical applications like autonomous navigation. Mechanistic models are often brittle, relying on difficult-to-measure parameters, while standard deep learning models are black boxes that fail to generalize, producing physically inconsistent predictions. Here, we introduce a physics-informed framework that learns the continuous-time dynamics of an Autonomous Underwater Vehicle (AUV) by discovering its underlying energy landscape. We embed the structure of Port-Hamiltonian mechanics into a neural ordinary differential equation (NODE) architecture, learning not to imitate trajectories but rather to identify the system’s Hamiltonian and its constituent physical matrices from observational data. Geometric consistency is enforced by representing rotational dynamics on the SE(3) manifold, preventing numerical error accumulation. Experimental validation reveals a stark performance divide. While a state-of-the-art black-box model matches our accuracy in simple, interpolative maneuvers, its predictions fail catastrophically under complex controls. Quantitatively, our physics-informed model maintained a mean 10 s position error of a mere 3.3 cm, whereas the black-box model’s error diverged to 5.4 m—an over 160-fold performance gap. This work establishes that the key to robust, generalizable models lies not in bigger data or deeper networks but in the principled integration of physical laws, providing a clear path to overcoming the brittleness of black-box models in critical engineering simulations.",

      "abstract": "This paper develops a contraction-certified trajectory-tracking and gain-selection framework for fully actuated autonomous underwater vehicles on SE(3). The vehicle dynamics are represented in port-Hamiltonian form with a Rayleigh-type dissipation potential, and a dual potential shaping controller provides an energy-structured rotational–translational cascade. Regional contraction certificates are derived separately for the rotational and translational subsystems. The rotational analysis uses fixed left-trivialised momentum coordinates and retains anisotropic-inertia effects and the complete off-diagonal differential coupling. The translational analysis applies to a general known symmetric positive-definite inertia matrix through an attitude-cover semidefinite programme, with an exact endpoint reduction for isotropic inertia. A scaled composite metric combines the subsystem certificates and guarantees every strict complete-cascade rate below the slower subsystem rate. Large initial attitude errors are handled by an energy-entry phase followed by contraction within a prescribed tube, without controller switching. The four-dimensional gain-selection problem is decomposed into two independent two-dimensional offline searches using bisection and SDP/LMI feasibility tests. Numerical studies on the ODIN AUV quantify the region–gain–rate trade-off and examine small-angle, large-angle, and near-antipodal manoeuvres. The framework certifies complete-cascade rates of 0.042096s−1 and 0.008524s−1 for the 60∘/60∘ and 150∘/80∘ regions, respectively.",

      "abstract": "Structure-preserving trajectory tracking control for a six-degree-of-freedom robotic manipulator is developed within the port-Hamiltonian framework. Error Hamiltonian is constructed by incorporating configuration and momentum tracking errors into the system energy. Based on this formulation, a momentum-based tracking controller with feedforward compensation and damping injection is derived without coordinate transformations or matching conditions. A disturbance estimator is further introduced to compensate unknown external torques. Energy-based analysis proves nominal closed-loop stability and uniform ultimate boundedness in the presence of estimation errors. Simulation results on a full rigid-body manipulator demonstrate accurate trajectory tracking under coupled and high-speed joint motions.",

      "abstract": "Exploiting the stochastic Hamiltonian structure, this paper investigates the robust fault-tolerant control (FTC) for stochastic port-Hamiltonian systems (SPHSs) with actuator faults. First, an energy-based robust FT controller is developed for SPHSs against the loss of actuator effectiveness. Then, an alternative condition, as well as its corresponding controller are given to extend the application of the proposed controller. Unlike the existing FT controllers, they are continuous, and there is no need to solve the Lyapunov function and Hamilton–Jacobi–Isaacs (HJI) inequalities associated with the nominal systems. Finally, an energy-based robust adaptive FT controller is presented for the faulty SPHSs to deal with parameter perturbations, and an alternative condition with its corresponding controller is also given. Both the adaptive controllers preserve the main stochastic Hamiltonian structure of the faulty systems. Compared to the existing adaptive controller, simulations on synchronous generators show the effectiveness of the proposed methods.",

Our simple model focuses on the relevant coupling structures and aims to reduce the unrelated complexity as much as possible. Then, we apply the port-Hamiltonian formalism to this model and its subsystems and investigate the interconnections. Finally, we apply a simple spatial discretization to the system to investigate the properties of the resulting finite-dimensional port-Hamiltonian system and to determine whether the order of coupling and discretization affect the resulting semi-discrete system.",

      "abstract": "Robot joints driven by permanent magnet synchronous motors (PMSM) often cannot have both superior accuracy and rapidity when they track target signals. The robot joints have fine dynamic characteristics and poor steady-state characteristics when the signal controller is used, or they have fine steady-state characteristics and poor dynamic characteristics when the energy controller is used. It is hard to make robot joints that have both superior dynamic and steady-state characteristics at once using a single control method. In order to solve this problem, the strategy of optimized cooperative control is proposed. First, an error port-controlled Hamiltonian (EPCH) energy controller and an adaptive backstepping sliding mode (ABSM) signal controller are designed. Second, an optimized cooperative control coefficient based on the position error of a robot joint is designed; this enables the system to switch smoothly between the EPCH energy controller and ABSM signal controller. Next, the strategy of optimized cooperative control is designed. In this way, robot systems can combine the advantages of the EPCH energy controller and the ABSM signal controller. Finally, simulation results demonstrate that using the strategy of optimized cooperative control gives robot joints outstanding control performance in terms of tracking accuracy and response rapidity.",

      "abstract": "In this work, we design a control strategy to be applied in a port-Hamilton representation of a liquid-mirror telescope for an alt-azimuth configuration. Starting from a dynamical model for an alt-azimuth liquid-mirror telescope based on Lagrange mechanics, a transformation to the port-Hamilton form is made. Such a dynamical model is obtained by computing the kinetic and potential energy of the telescope and substituting them in the Euler–Lagrange equation of motion. Then, for the transformation to the port-Hamiltonian form, we obtain the relation between the Hamiltonian and the Lagrangian. The resulting open-loop model based on the Hamiltonian function is controlled using an extension of the interconnection and damping-assignment passivity-based control aiming for a robust and accurate steady behavior in the closed loop while tracking a star’s position. For comparison purposes, two different control strategies are applied to the Lagrangian model, inverse-dynamics control and sliding mode super-twisting control. Since the light is collected by the principal mirror of the telescope while tracking a star, we make a description of the liquid mirror’s behavior. The tracking star’s position is described as a function of the observer’s position and the star’s coordinates as well as the date of observation. The simulations’ results show that the port-Hamilton control has a good transitory and steady response as well as great accuracy competing with that of inverse-dynamics control but with greater robustness and no chattering drawback.",

      "abstract": "In this paper, we propose a method for deriving energetic-property-preserving numerical schemes for coupled systems of two given natural systems. We consider the case where the two systems are interconnected by the action–reaction law. Although the derived schemes are based on the discrete gradient method, in the case under consideration, the equation of motion is not of the usual form represented by using the skew-symmetric matrix. Hence, the energetic-property-preserving schemes cannot be obtained by straightforwardly using the discrete gradient method. We show numerical results for two coupled systems as examples; the first system is a combination of the wave equation and the elastic equation, and the second is of the mass–spring system and the elastic equation.",

      "abstract": "DC microgrid applications include electric vehicle systems, shipboard power systems, and More Electric Aircraft (MEA), which produce power at a low voltage level. Rapid developments in hydrogen fuel cell (FC) energy have extended the applications of multi-phase parallel interleaved step-up converters in stabilizing DC bus voltage. The cascade architecture of power converters in DC microgrids may lead to large oscillation and even risks of instability given that the load converters considered as loads feature constant power load (CPL) characteristics. In this article, the output DC bus voltage stabilization and the current sharing of a multi-phase parallel interleaved FC boost converter is presented. The extended Port-Hamiltonian (pH) form has been proposed with the robust controller by adding an integrator action based on the Lyapunov−Energy function, named “Adaptive Hamiltonian PI controller”. The stability and robustness of the designed controller have been estimated by using Mathematica and Matlab/Simulink environments and successfully authenticated by performing experimental results in the laboratory. The results have been obtained using a 2.5 kW prototype FC converter (by two-phase parallel interleaved boost converters) with a dSPACE MicroLabBox platform. The FC main source system is based on a fuel reformer engine that transforms fuel methanol and water into hydrogen gas H2 to a polymer electrolyte membrane FC stack (50 V, 2.5 kW).",

The device is made from soft material called an ionic polymer-metal composite (IPMC). The IPMC consists of a base film of a polyelectrolyte gel and a double layer of plated metal electrodes. The electrodes of the experimental IPMC are sectioned, and it is implemented as a control system with four pairs of inputs/outputs. We stabilize the system, and detect changes in dynamics by using the control representation.",

      "abstract": "The problem of voltage regulation in unknown constant resistive loads is addressed in this paper from the nonlinear control point of view for second-order DC-DC converters. The converters’ topologies analyzed are: (i) buck converter, (ii) boost converter, (iii) buck-boost converter, and (iv) non-inverting buck-boost converter. The averaging modeling method is used to model these converters, representing all these converter topologies with a generalized port-Controlled Hamiltonian (PCH) representation. The PCH representation shows that the second-order DC-DC converters exhibit a general bilinear structure which permits to design of a passivity-based controller with PI actions that ensures the asymptotic stability in the sense of Lyapunov. A linear estimator based on an integral estimator that allows reducing the number of current sensors required in the control implementation stage is used to determine the value of the unknown resistive load. The main advantage of this load estimator is that it ensures exponential convergence to the estimated variable. Numerical simulations and experimental validations show that the PI passivity-based control allows voltage regulation with first-order behavior, while the classical PI controller produces oscillations in the controlled variable, significantly when the load varies.",

      "abstract": "Starting from the general topology and the main elements that connect a microgrid represented by a DC power source to the main grid, this article presents the performance of the control system of a DC-AC converter. The main elements of this topology are the voltage source inverter represented by a DC-AC converter and the network filters. The active Insulated Gate Bipolar Transistor (IGBT) or Metal–Oxide–Semiconductor Field-Effect Transistor (MOSFET) elements of the DC-AC converter are controlled by robust linear or nonlinear Port Controlled Hamiltonian (PCH) controllers. The outputs of these controllers are modulation indices which are inputs to a Pulse-Width Modulation (PWM) system that provides the switching signals for the active elements of the DC-AC converter. The purpose of the DC-AC converter control system is to maintain ud and uq voltages to the prescribed reference values where there is a variation of the three-phase load, which may be of balanced/unbalanced or nonlinear type. The controllers are classic PI, robust or nonlinear PCH, and their performance is improved by the use of a properly trained Reinforcement Learning-Twin Delayed Deep Deterministic Policy Gradient (RL-TD3) agent. The performance of the DC-AC converter control systems is compared using performance indices such as steady-state error, error ripple and Total Harmonic Distortion (THD) current value. Numerical simulations are performed in Matlab/Simulink and conclude the superior performance of the nonlinear PCH controller and the improvement of the performance of each controller presented by using an RL-TD3 agent, which provides correction signals to improve the performance of the DC-AC converter control systems when it is properly trained.",

      "abstract": "As modern power systems grow increasingly complex, there is a pressing need for stability analysis methods capable of handling nonlinear dynamics while providing physically meaningful and reliable stability indices. Port-Hamiltonian (PH) frameworks have emerged as strong candidates in this regard, offering inherently stable formulations, energy-consistent representations, and modular plug-and-play scalability. However, the practical deployment of PH-based stability analysis remains hindered by the absence of reliable, high-fidelity parameter identification methods that rely on sensor measurements to capture system dynamics while remaining compatible with PH model structures. This paper addresses that gap by proposing a comprehensive three-stage data-driven identification framework for PH modeling of synchronous generators—the central dynamic component of any power system. While the IEEE Standard 115 provides established procedures for transient parameter identification, it exhibits fundamental limitations when applied to PH modeling, including single-scenario identifiability constraints, noise-sensitive derivative-based formulations that amplify sensor measurement errors, and the inability to decouple generator-internal damping from grid contributions. The proposed framework resolves these limitations through multi-scenario excitation using sensor-acquired voltage and current signals, derivative-free state consistency optimization, and physics-based regularization that enforces PH structure preservation. Complete identification of eight key parameters (H, D, Xd, Xq, Xd′, Xq′, Tdo′, Tqo′) is achieved with errors ranging from 1.26% to 9.10%, and validation confirms RMS rotor angle errors below 1.2° and speed errors below 0.15%, demonstrating suitability for transient stability analysis, passivity-based control design, and oscillation damping assessment.",

      "abstract": "In order to stabilize the fluctuation of wind power and maintain a stable power output, a complementary control idea is proposed. This idea aims to make the output power from two wind farms complement each other. This study proposes a distributed control strategy to solve the complementary control problem of wind turbines in two offshore wind farms on the basis of the Hamiltonian energy theory. The proposed control strategy not only ensures synchronization for wind turbines in the same farm but also keeps the combined output power of the two wind farms stable. First, through the Hamiltonian realization, the single-machine model of a wind turbine is transformed into a port-controlled Hamiltonian system with dissipation (PCHD). Subsequently, the Hamiltonian energy control law is developed on the basis of the energy-shaping method to adjust the Hamiltonian energy function. The complementary control of the two wind farms is designed to synchronize the wind turbines within an individual wind farm and keep the combined output of the two wind farms stable. Furthermore, the complementary control strategy is modified to address the communication delay between the two wind farms by incorporating time delay into the control problem. Finally, the effectiveness of the distributed complementary control has been verified via simulations.",

      "abstract": "With large-scale development of offshore wind power and the increasing scale of power grid interconnection, more and more attention has been drawn to the stable operation of wind power units. When the wide area measurement system (WAMS) is applied to the power system, the time delay mainly occurs in the signal measurement and transmission of the power system. When 10MW wind turbines transmit information through complex communication network, time delay often exists, which leads to the degradation of performance and instability for system. This affects the normal operation of a wind farm. Therefore, in this paper, the distributed control problem of doubly fed wind turbines with input time delay is studied based on the Hamiltonian energy theory. Firstly, the Port-controlled Hamiltonian system with Dissipation (PCH-D) model is implemented with the Hamiltonian energy method. Then, the Casimir function is introduced into the PCH-D model of the single wind turbine system to stabilize the time delay. The wind turbine group is regarded as one network and the distributed control strategy is designed, so that the whole wind turbine cluster can remain stable given a time delay occurring in the range of 30–300 ms. Finally, simulation results show that the output power of the wind turbine cluster with input delay converges to the expected value rapidly and remains stable. Additionally, the system error caused by time delay is greatly reduced. This control method can effectively solve the problem of input time delay and improve the stability of the wind turbine cluster. Moreover, the method proposed in this paper can adopt the conventional time step of dynamic simulation, which is more efficient in calculation. This method has adaptability in transient stability analysis of large-scale power system, however, the third-order mathematical model used in this paper cannot be used to analyze the internal dynamics of the whole power converter.",

      "abstract": "To support doubly fed wind turbine (DFWT) groups in offshore wind farms, this paper proposes a distributed coordinated control based on the Hamiltonian energy theory. This strategy provides global stability to closed-loop systems and facilitates output synchronization. First, a model of a DFWT is realized as a port-controlled Hamiltonian system with dissipation (PCH-D), and the single-machine model is expanded into a multi-machine model of a wind turbine group. Then, by using the design methodology of distributed Hamiltonian systems, a distributed coordinated control is presented for a multi-machine PCH-D system. Furthermore, to investigate failures in wind turbine groups, they are divided into two cases: the separation of failed machines from the system, and the grid-connected operation of failed machines after a fault. These cases correspond to undirected and directed graphs, respectively. Finally, simulations prove that distributed coordinated control enhances the reliability and autonomy of wind turbine groups in offshore wind farms.",

      "abstract": "This paper presents an efficiency optimization controller for a permanent magnet synchronous motor (PMSM) of an electric vehicle. A new loss model is obtained based on the permanent magnet synchronous motor’s energy balance equation utilizing the theory of the port-controlled Hamiltonian system. Since the energy balance equation is just the power loss of the PMSM, which provides great convenience for us to use the energy method for efficiency optimization. Then, a new loss minimization algorithm (LMA) is designed based on the new loss model by adjusting the ratio of the excitation current in the d–q axis. Moreover, the proposed algorithm is achieved by the principle of the energy shape method of the Hamiltonian system. Simulations are finally presented to verify effectiveness. The main results of these simulations indicate that the dynamic performance of the drive is maintained and the efficiency increase is up to about 7% compared with the id=0 control algorithm, and about 4.5% compared with the conventional LMA at a steady operation of a PMSM.",

In this paper, the fluid–solid interaction is considered in a vessel attached to the free tip of a cantilever beam. Governing coupled equations of the system include the Euler–Bernoulli equation for bending of a beam, torsion of a beam, 2-D motion of the rigid vessel, and rotating shallow water equation of fluid sloshing in the vessel. As an essential portion in the numerical simulation of the vibration control of this fluid–plate system is the accurate modeling of sloshing; the partial differential equations of the system are modified by approximation of velocity profile. The suggested method is validated by experimental results of a piezoelectric actuated clamped rectangular plate holding a cylindrical vessel. These sloshing interactions with elastic test cases illustrate the mass conservative characteristics of the method as well as its stability in a prompt change of the vessel situations.",

      "abstract": "This study presents a complex variable neural network (CVNN) controller designed for unmanned aerial vehicles (UAVs) using the port-Hamiltonian formulation with non-holonomic constraints. The approach begins by deriving the dynamic model of a quadrotor UAV in port-Hamiltonian form, where the Hamiltonian is constructed from the system&amp;rsquo;s total kinetic and potential energies. Dirac structures are implemented to preserve the system&amp;rsquo;s structural properties while incorporating non-holonomic constraints specifically in the attitude loop. The proposed control architecture decouples the attitude and position control loops, with each utilizing a CVNN controller designed through Lyapunov stability analysis. Theoretical proofs establish the stability of both control loops, while numerical simulations demonstrate the effectiveness of the proposed approach for trajectory tracking tasks. Comparative analysis against existing controllers shows superior performance in reducing root mean square errors while maintaining reasonable control effort. The results confirm that the CVNN controller effectively manages the UAV&amp;rsquo;s dynamic behavior even with non-holonomic constraints limiting the vehicle&amp;rsquo;s orientation range.",

      "abstract": "This study evaluates the performance and robustness of a port-Hamiltonian controller for the links of a liquid mirror telescope and a PI controller for the rotation of its liquid mirror, using ROS2 and Gazebo. The telescope links track a star’s apparent daily motion, while the liquid mirror achieves the required angular speed for a desired focal length. These references are computed based on the star’s name and focal length input. The telescope’s physical properties, including dimensions, masses, inertia, and 3D models, are stored in a Unified Robot Description Format (URDF) file, enabling Gazebo to initialize accurate simulations. Joint information—state interfaces (angular position and speed) and command interfaces (effort)—is also defined in the URDF. Controller configurations, including gains, bounds, and control parameters, are stored in a YAML file, ensuring seamless integration with Gazebo. The evaluation encompasses key performance metrics. For the two-link telescope, tracking accuracy, settling time, control effort, and energy efficiency are analyzed. For the liquid mirror, the primary focus is on tracking precision. The port-Hamiltonian controller’s performance is compared to inverse dynamics and super-twisting sliding mode controllers. Results show that the port-Hamiltonian controller achieves a favorable balance between accuracy and energy efficiency, exhibiting smoother control actions that reduce energy consumption and actuator wear. Its stability under varying conditions ensures high precision for astronomical observations. Furthermore, ROS2 and Gazebo provide a risk-free environment for extensive testing, facilitating a smooth transition to real-world implementation.",

      "abstract": "In most physical models of brass instruments, the air jet (located at the exciter) is governed by an equation of Bernoulli-type for which basic, unsteady or lossy versions are available. The non-linearity introduced by such model is known to be of utmost importance for wind instruments: it is responsible for self-oscillations when fed by a power source. However, this type of model is unable to make the air flow work at a mobile boundary (lip) as it does not account for any transverse component (the vertical dimension during normal brass playing) in the velocity field. In this sense, it is ill adapted to properly address the power exchanges between the jet and the lips. This paper addresses the following twofold issue. The first issue is the derivation of an air flow model in the unsteady case that restores the fundamental property of passivity at boundaries. The second issue is the test of its relevance in self-oscillating contexts, based on passive-guaranteed simulations of a simplified complete instrument. To make the air flow model as simple as possible, its derivation relies on standard Bernoulli assumptions (irrotational, incompressible flow without loss) except for the boundary conditions at the wall. It is derived in two steps. First, we solve the 2D velocity and pressure fields of the Euler equation for boundary conditions that are adapted to a moving lip. Second, we derive a macroscopic model based on averaged velocities and pressures. This yields a finite dimensional differential system which proves to be equivalent to the original one, in the sense that both the velocity and the pressure fields can be recovered from the macroscopic variables. Moreover, it preserves the power balance of the original physical system. Then, a simplified model of an instrument is built by connecting this system to a lip (mass-spring-damper) and to a conservative straight pipe with an ideally dissipative termination. Passivity is fulfilled and the complete power balance is explicitly encoded by recasting the model into the “Port-Hamiltonian formulation”. A numerical scheme that preserves passivity is proposed to simulate the complete system supplied by an ideal air pressure generator. Finally, results are compared with those based on the standard Bernoulli equation.",

In order to give a direct discrete time design method for PCHS, firstly an appropriate discrete gradient is proposed, which enables the derivation of a discrete time equation corresponding to the discrete time counterpart of Hamiltonian Systems. Using this proposed discrete-time model, the discrete-time counterpart of Passivity Based Control (PBC) technique is developed for n-degreesof-freedom mechanical systems. The discrete-time control rules which correspond to the energy shaping and damping assignment are obtained directly using the discrete time model of the desired system and the discrete time model of the open loop systems. To illustrate the effectiveness of the proposed method, two non-separable and under actuated examples are investigated and the simulation results are given.",

      "abstract": "<jats:p xml:lang=\"fr\">&lt;abstract&gt;&lt;p&gt;This article mainly uses two methods of solving the conservation laws of two partial differential equations and a system of equations. The first method is to construct the conservation law directly and the second method is to apply the Ibragimov method to solve the conservation laws of the target equation systems, which are constructed based on the symmetric rows of the target equation system. In this paper, we select two equations and an equation system, and we try to apply these two methods to the combined KdV-MKdV equation, the Klein-Gordon equation and the generalized coupled KdV equation, and simply verify them. The combined KdV-MKdV equation describes the wave propagation of bound particles, sound waves and thermal pulses. The Klein-Gordon equation describes the nonlinear sine-KG equation that simulates the motion of the Josephson junction, the rigid pendulum connected to the stretched wire, and the dislocations in the crystal. And the coupled KdV equation has also attracted a lot of research due to its importance in theoretical physics and many scientific applications. In the last part of the article, we try to briefly analyze the Hamiltonian structures and adjoint symmetries of the target equations, and calculate their linear soliton solutions.&lt;/p&gt;&lt;/abstract&gt;</jats:p>",

To do so, the theory of boundary control system is employed. This definition encompasses problems from mechanics that cannot be handled by the geometric setting given in the seminal paper by van der Schaft and Maschke in 2002. Many worked-out examples stemming from continuum mechanics and physics are presented in detail, and a particular focus is given to the functional spaces in duality at the boundary of the geometrical domain. For each example, the connection between the differential operators and the associated Hilbert complexes is illustrated.",

      "abstract": "In this paper, we extended the port-Hamiltonian framework by introducing the concept of Stokes-Lagrange structure, which enables the implicit definition of a Hamiltonian over an $N$-dimensional domain and incorporates energy ports into the system. This new framework parallels the existing Dirac and Stokes-Dirac structures. We proposed the Stokes-Lagrange structure as a specific case where the subspace is explicitly defined via differential operators that satisfy an integration-by-parts formula. By examining various examples through the lens of the Stokes-Lagrange structure, we demonstrated the existence of multiple equivalent system representations. These representations provide significant advantages for both numerical simulation and control design, offering additional tools for the modeling and control of port-Hamiltonian systems.",

We show that there is a boundary triple associated to this system. Hence, we can characterize all boundary conditions that provide unique solutions that are non-increasing in the Hamiltonian. As a by-product we develop the theory of quasi Gelfand triples. Adding \"natural\" boundary controls and boundary observations yields scattering/impedance passive boundary control systems. This framework will be applied to the wave equation, Maxwell's equations and Mindlin plate model. Probably, there are even more applications.",

Along the way, we also establish global stability estimates. We consider both systems with distributed control and observation and systems with boundary control and observation, and we treat them in a unified manner. Applications are given to nonlinearly controlled collocated systems and to nonlinearly controlled port-Hamiltonian systems.",

Moreover, by defining suitable Dirac and resistive structures, we show that it admits a~representation as a~port-Hamiltonian system. Thereafter, we consider dependence on initial and input data. We show that the current and the magnetic vector potential can be estimated by means of the initial magnetic vector potential and the voltage. We also analyse the free dynamics of the system and study the asymptotic behavior of the solutions for $t\\to\\infty$.",

We define Leibniz-Dirac structures which lead to a natural generalization of Dirac and Riemannian structures, for instance. From modeling point of view, Leibniz-Dirac structures make it easy to formulate implicit dissipative Hamiltonian systems. We give their exact characterization in terms of vector bundle maps from the tangent bundle to the cotangent bundle and vice verse. Physical systems which can be formulated in terms of Leibniz-Dirac structures are discussed.",

We show that there exists an analogous picture in the dynamics of objects for which the configuration space is $\\wedge^n T M$, if we make use of certain structures of graded bundles of degree $n$, i.e. objects generalizing vector bundles (for which $n=1$). For instance, the role of $TT^*M$ is played in our approach by the manifold $\\wedge^nT M\\wedge^nT^*M$, which is canonically a graded bundle of degree $n$ over $\\wedge^nT M$. Dynamics of strings and the Plateau problem in statics are particular cases of this framework.",

      "abstract": "Many mechanical systems are large and complex, despite being composed of simple subsystems. In order to understand such large systems it is natural to tear the system into these subsystems. Conversely we must understand how to invert this tearing procedure. In other words, we must understand interconnection of subsystems. Such an understanding has been already shown in the context of Hamiltonian systems on vector spaces via the port-Hamiltonian systems program, in which an interconnection may be achieved through the identification of shared variables, whereupon the notion of composition of Dirac structures allows one to interconnect two systems. In this paper, we seek to extend the program of the port-Hamiltonian systems on vector spaces to the case of Lagrangian systems on manifolds and also extend the notion of composition of Dirac structures appropriately. In particular, we will interconnect Lagrange-Dirac systems by modifying the respective Dirac structures of the involved subsystems. We define the interconnection of Dirac structures via an interaction Dirac structure and a tensor product of Dirac structures. We will show how the dynamics of the interconnected system is formulated as a function of the subsystems, and we will elucidate the associated variational principles. We will then illustrate how this theory extends the theory of port-Hamiltonian systems and the notion of composition of Dirac structures to manifolds with couplings which do not require the identification of shared variables. Lastly, we will show some examples: a mass-spring mechanical systems, an electric circuit, and a nonholonomic mechanical system.",

      "abstract": "In the process of large-scale wind farms integration, the time delay is usually caused by the introduction of wide area control signal, which leads to the unstable operation of integrated transmission system. In order to solve this problem, using the control principle of interconnection and damping assignment passivity-based (IDA-PB), this paper puts forward a control method which applies voltage source converter high voltage direct current (VSC-HVDC) technology to the integrated system of time-delay wind farm and keeps the system running stably. In this method, the framework of time-delay port controlled Hamiltonian (PCH) system is constructed, and the energy shaping of the system is carried out by extending the IDA-PB control principle, thus the feedback controller of the system is designed. Around the problem of time-delay stabilization, the stability criterion is obtained by constructing Lyapunov-Krasovskii functional and introducing free weighting matrices. Finally, the simulation results show that the proposed method can effectively solve the time delay problem of the integrated transmission system and avoid the performance deterioration of the system.",

The first one, based on the invariance of its coordinates, is the representation in Riemann coordinates which has been applied successfully for the stabilization of linear and non-linear hyperbolic systems of conservation laws. The second representation is based on physical modelling and leads to port Hamiltonian systems which are extensions of infinite-dimensional Hamiltonian systems defined on Dirac structure encompassing pairs of conjugated boundary variables. In a first instance the port Hamiltonian formulation is recalled with respect to a canonical Stokes-Dirac structure and then derived in Riemann coordinates. In a second instance the conditions on the boundary feedback relations derived with respect to the Riemann invariants are expressed in terms of the port boundary variable of the Hamiltonian formulation and interpreted in terms of the dissipation inequality of the Hamiltonian functional. The p-system and the Saint-Venant equations arising in models of irrigation channels are the illustrating examples developed through the paper.",

However, general results for the latter have been difficult to interpret in the network language. The aim of this paper is to derive conditions under which a port-Hamiltonian with general linear Kirchhoff's boundary conditions can be written as a system of $ 2\\times 2 $ hyperbolic equations on a metric graph $ \\Gamma $. This is achieved by interpreting the matrix of the boundary conditions as a potential map of vertex connections of $ \\Gamma $ and then showing that, under the derived assumptions, that matrix can be used to determine the adjacency matrix of $ \\Gamma $",

      "abstract": "Port-Hamiltonian systems (PHS) theory is a recent but already well-established modelling approach for non-linear physical systems. Some studies have shown lately that PHS frameworks are relevant for modelling and control of swarm and multi-agent systems. We identify in this contribution a general class of microscopic force-based pedestrian models that can be formulated as a port-Hamiltonian system. The pedestrian PHS has linear structure and dissipation components. Non-linear effects come from isotropic pedestrian interactions. Simulation results on a torus with disordered initial states show that the port-Hamiltonian pedestrian model can exhibit different types of dynamics. They range from relaxed speed models with no interaction, dynamical billiards, or crystallization dynamics to realistic pedestrian collective behaviors, including lane and strip formation for counter and crossing flow. The port-Hamiltonian framework is a natural multiscale description of pedestrian dynamics as the Hamiltonian turns out to be a generic order parameter that allows us to identify specific behaviours of the dynamics from a macroscopic viewpoint. Particular cases even enable through energy balance to determine the Hamiltonian behavior without requiring the tedious computation of the microscopic dynamics. Using PHS theory, we systematically identify a critical threshold value for the Hamiltonian, which relies only on exogenous input and can be physically interpreted.",

Path following control is investigated mainly for mechanical systems since the desired path is characterized by its ‘position’. Therefore, most of the existing results use the nature of second order differential equations since mechanical systems are described by them. The present paper proposes a new path following controller for 3rd order differential equations described by the port-Hamiltonian form. This is done by generalizing the authors’ former result on passive velocity field control for mechanical systems.",

The coordinated control of the grid-side and the motor-side are applied in Matlab/simulink, which the motor-side is started after the grid-side is achieved up to stable. The controlled system can be achieved that DC bus voltage controllable, unity power factor, energy bidirectional flow, IM run in the four-quadrant, etc.",

Hamiltonian dynamics has two advantages: 1) there is no need to write down the complete equations of motion explicity and thus help to solve the problem much quicker and 2) it can help understanding and designing controllers using the energy flow, Hamiltonian phase space and port-Hamiltonian representation for system evolution. The present paper highlights the importance of using the Hamiltonian dynamics for helicopter flight dynamics, exemplifying it for the helicopter pitch motion and for a 6-DOF nonlinear model. The paper shows that, using Hamiltonian formulation, one can define energy stagnations areas in the Hamiltonian phase plane and dissipative non-passive terms in the equations of motion that need to be restrained when designing a helicopter controller. The extension of the Hamiltonian to the port-Hamiltonian formulation can be used to design nonlinear controllers robust to system nonlinearities.",

      "abstract": "The theory of port-Hamiltonian systems provides a framework for the geometric description of network models of physical systems. It turns out that port-based network models of physical systems immediately lend themselves to a Hamiltonian description. While the usual geometric approach to Hamiltonian systems is based on the canonical symplectic structure of the phase space or on a Poisson structure that is obtained by (symmetry) reduction of the phase space, in the case of a port-Hamiltonian system the geometric structure derives from the interconnection of its sub-systems. This motivates to consider Dirac structures instead of Poisson structures, since this notion enables one to define Hamiltonian systems with algebraic constraints. As a result, any power-conserving interconnection of port-Hamiltonian systems again defines a port-Hamiltonian system. The port-Hamiltonian description offers a systematic framework for analysis, control and simulation of complex physical systems, for lumped-parameter as well as for distributed-parameter models.",

The concept of dissipativity has been extended to a more general system theoretic setting via port-Hamiltonian systems and this framework is a driver of innovations in many of areas of science and technology. The particular strength of the approach lies in the modularity of modeling, the strong geometric, analytic and algebraic properties and the very good approximation properties.",

      "abstract": "Organizing physics has been a long-standing preoccupation of applied category theory, going back at least to Lawvere. We contribute to this research thread by noticing that Hamiltonian mechanics and gradient descent depend crucially on a consistent choice of transformation -- which we call a reaction structure -- from the cotangent bundle to the tangent bundle. We then construct a compositional theory of reaction structures. Reaction-based systems offer a different perspective on composition in physics than port-Hamiltonian systems or open classical mechanics, in that reaction-based composition does not create any new constraints that must be solved for algebraically. The technical contributions of this paper are the development of symmetric monoidal categories of open energy-driven systems and open differential equations, and a functor between them, functioning as a\"functorial semantics\"for reaction structures. This approach echoes what has previously been done for open games and open gradient-based learners, and in fact subsumes the latter. We then illustrate our theory by constructing an n-fold pendulum as a composite of n-many pendula.",

      "abstract": "This paper presents a system representation that can be applied to the description of the interaction between systems connected through common boundaries. The systems consist of partial differential equations that are first order with respect to time, but spatially higher order. The representation is derived from the instantaneous multisymplectic Hamiltonian formalism; therefore, it possesses the physical consistency with respect to energy. In the interconnection, particular pairs of control inputs and observing outputs, called port variables, defined on the boundaries are used. The port variables are systematically introduced from the representation.",

      "abstract": "The present manuscript concerns the design of structure-preserving discretization methods for the solution of systems of boundary controlled Partial Differential Equations (PDEs) thanks to the port- Hamiltonian formalism. We first provide a general structure of infinite-dimensional port-Hamiltonian systems (pHs) for which the Partitioned Finite Element Method (PFEM) straightforwardly applies. The proposed strategy is particularised to abstract multidimensional linear hyperbolic and parabolic systems of PDEs. Then we show that instructional model problems based on the wave equation, Mindlin equation and heat equation fit within this unified framework. Secondly we introduce the ongoing project SCRIMP (Simulation and ContRol of Interactions in Multi-Physics) developed for the numerical simulation of infinite-dimensional pHs. SCRIMP notably relies on the FEniCS open-source computing platform for the finite element spatial discretization. Finally, we illustrate how to solve the considered model problems within this framework by carefully explaining the methodology. As additional support, companion interactive Jupyter notebooks are provided.",

Through rewriting the CRTBP into Port-Hamiltonian framework, we are allowed to design the feedback controller through energy-shaping and dissipation injection. The closed-loop Hamiltonian is a candidate of the Lyapunov function to establish nonlinear stability of the designed equilibrium, which enlarges the application region of feedback controller compared with that based on linearized dynamics. Results show that the Port-Hamiltonian approach allows us to successfully stabilize the Lagrange points, where the Linear Quadratic Regulator (LQR) may fail. The feedback system based on Port-Hamiltonian approach is also robust against white noise in the inputs.",

      "abstract": "In this paper, a novel methodology of nonlinear control is used, and a passivity-based control of contractive port-controlled Hamiltonian (PCH) systems is applied to a permanent magnet synchronous motor (PMSM). This methodology, also called “IDA-PBC” (Trajectory Injection and Damping Assignment—Passivity-Based Control), uses passivity-based control of PCH systems “IDA-PBC” and exploits the properties of contractive Hamiltonian systems, resulting in a closed loop with its contractive system desired dynamics, thus obtaining an exponential trajectory tracking without relying on the error coordinates. In this system, a few steps are proposed in order to divide and modularize the methodology so it can be redesigned or reapplied in other systems by the reader. First, we define the model and set the way to solve the “matching equation.” Then the feasible and reference trajectories are obtained. After that, the desired Dirac structure and energy function are set in order to meet the methodology requirements. Finally, the control law is obtained, and simulations were performed. The desired trajectories (which can be time varying) are arbitrarily set, and the exponential convergence to the desired trajectories is archived. The results obtained from the simulations are an initial approach to the improvement of propulsion algorithms in electrified vehicles, where linear controls are still used and have poor performance compared to the visited methodology.",

Using energy-shaping and passivity-based control(PBC) method, the control principle of PMLSM is given. The control laws is presented in load known conditions. The equilibrium stability is analyzed and the feedback controller is designed for the control system of PMLSM.  A simulation model has been established in the Simulink/Matlab environment and the simulation results are given. In order to compare the control effect, traditional PID control simulation results are also provided in the same conditions. The simulation results show that the proposed scheme has a better performance than that of conventional PID controller.",

      "abstract": "Hamiltonian method based on action micro-control is widely used in the control of mechanical arm synchronous motor. In order to realize the combination of robot dynamics and drive motor control, Hamiltonian control method is used in this paper to exploit a novel controller for robot, which can be used for better steady-state characteristics in the system. However, dynamic response of port-controlled Hamiltonian (PCH) of control system is slower, so the related control method is exploited and coordinated with the proportional-derivative (PD) plus gravity compensation. At this time, the system has both the fast dynamic response of the PD and the steady state of the PCH. The reverse motor method is used and the two controllers are combined by current conversion to realize the overall control of the robot and the drive motor. The robot drive motor is controlled, and the robot joint position control is combined with the drive motor current control by current conversion. It can be seen from the simulation results that the coordinately controlling the end position of robot can reach the desired position quickly and accurately. Moreover, compared with the separate control of PD plus gravity compensation and PCH control method, it is proved that this scheme has both a fast dynamic process and better performance and ability to resist load torque disturbance. So control method proposed in this paper has a good application prospect",

      "abstract": "This paper presents a passivity-based controller design (PBC) aimed at stabilizing DC-DC power electronic converters with nonlinear dissipative loads. The converters considered in this work are the buck, the boost and the buck-boost. First, Bond Graph technique is used to obtain the flat output of each converter model. The controller is designed within the port-Hamiltonian (pH) framework, ensuring stability and other desired closed-loop properties. To this aim a desired closedloop dynamics in pH form with a quadratic storage function and a flat-output-inspired change of variables are proposed, which are common to the three converters. The controllers that render the closed-loop dynamics in the desired pH form are obtained via model matching. This design has two major advantages. The first is that the so-called matching equation can be solved by construction; thus, the cumbersome task of solving partial differential equations is avoided. The second advantage is that in all the converters treated the closed-loop dynamics is linear; thus, the performance of the control system can be easily determined via the tuning of the eigenvalues of the closed-loop evolution matrix. The performance is assessed through digital simulation.",

      "abstract": "This paper contributes a passivity-based approach to obtain a control law that robustifies Port-Hamiltonian (pH) control systems under external and state-dependent disturbances using disturbance observers (DO). A twostage design procedure is used to define the Disturbance Observed Based Control (DOBC) scheme. In the first stage a passivity based control law, called Interconnection and Damping assignment (IDA-PBC) is designed in the Bond Graph (BG) domain via BG prototyping, using an undisturbed model of the physical system. This stage is not the main issue of this paper and therefore the IDA-PBC law will be assumed to be known. The second stage, the main result of this paper, consists in the design of the DO and its integration with the IDA-PBC control law. The DO is derived in the BG domain via the integration of the residual signal computed from a Diagnostic Bond Graph (DBG). The methodology is developed through examples in the BG domain and formalized and extended in the pH framework.",

The purpose of this paper is to develope a unified mathematic model of such a boom system which is a multi-domain system consisting of boom structure and hydraulic drive system. The model is formulated within the port-Hamilton (PH) formalism using the definition of hydraulic system and elastic boom structure as (Stokes-) Dirac structures. The Port-Hamiltonian systems can be easily interconnected thus allowing the description of a complex system as a composition of subsystems. This property is especially useful to model a multi-domain system with energy exchanges between subsystems. Considering the boom structure as a Timoshenko beam, the luffing operation of boom system is simplified in a plane coordinate system. The Port-Hamiltonian model of the hydraulic system and the boom structure are described with details separately, a structure-preserving discretization is applied to transfer the distributed-parameter boom model into a lumped-parameter model. Then the interconnections between the subsystems are illustrated and a complete simulation including hydraulic system is accomplished in MATLAB/Simulink.",

The continuous dynamics of the soft robot are modeled by the differential geometry of Cosserat beams. Through a finite-dimensional truncation, a reduced port-Hamiltonian model is obtained that preserves desirable passivity conditions. Exploiting the passivity, we propose a stabilizing energy-shaping controller that ensures the potential energy is minimal at the desired end-effector configuration. Finally, the effectiveness of the energy-based controller is demonstrated through simulations of a soft manipulator inspired by the tentacle of an octopus.",

We show that these systems not only arise when there are constraints coming from the underlying physics, but many standard PDE models can be seen as an adHDAE on an extended state space. This reflects the fact that models often include closure relations and structural properties. We present a unifying operator theoretic approach to analyze the properties of such operator equations and illustrate this by several applications.",

      "abstract": "We study the problem of state transition on a finite time interval with minimal energy supply for linear port-Hamiltonian systems. While the cost functional of minimal energy supply is intrinsic to the port-Hamiltonian structure, the necessary conditions of optimality resulting from Pontryagin's maximum principle may yield singular arcs. The underlying reason is the linear dependence on the control, which makes the problem of determining the optimal control as a function of the state and the adjoint more complicated or even impossible. To resolve this issue, we fully characterize regularity of the (differential-algebraic) optimality system by using the interplay of the cost functional and the dynamics. In case of the optimality DAE being characterized by a regular matrix pencil, we fully determine the control on the singular arc. In case of singular matrix pencils of the optimality system, we propose an approach to compute rank-minimal quadratic perturbations of the objective such that the optimal control problem becomes regular. We illustrate the applicability of our results by a general second-order mechanical system and a discretized boundary-controlled heat equation.",

      "abstract": "The nonlinearity of chemical processes primarily arises from strong interdependencies among state variables and the presence of time delays. This characteristic leads to complex dynamic behaviors such as non-minimum phase responses, posing significant challenges for control design. This study presents a novel control strategy that integrates Pade approximation of time delay with a tracking-error-based control law within a port-Hamiltonian (PH) framework. Specifically, the Pade approximation is employed to effectively handle the time delay by approximating exponential delay terms, thereby facilitating its incorporation into the control design and enhancing the robustness of the closed-loop system. Concurrently, the tracking-error-based feedback laws ensure the asymptotic convergence of system trajectories to the desired reference trajectories, even in the presence of non-minimum phase dynamics. The proposed methodology is illustrated through simulations on the quadruple-tank process - a benchmark nonlinear system with inherent time delays. Results demonstrate that the proposed control scheme successfully mitigates the adverse effects of time delay and achieves the closed-loop stabilization at the target equilibrium point.",

      "abstract": "This paper discusses passivity-based boundary controls of flexible beams with large deformations in terms of a distributed parameter port-Hamiltonian system. Distributed parameter systems have been mainly studied from the viewpoint of analytical methods. However, analytical solutions cannot be always derived from nonlinear distributed parameter systems such as the flexible beam. A distributed parameter port-Hamiltonian system is a standard control representation that can be applied to such a complex system without model reductions. The passivity-based boundary controls consist of boundary damping assignment and boundary energy shaping. Inputs and outputs for the controls are systematically derived from the system representation. Finally, we illustrate numerical results of the controls for stabilizing the flexible beam and shaping its potential energy.",

Hydraulic arms are very important components in field robotics, such as construction, agriculture, rescue , demining robotics and so on since hydraulic arms are superior to electric arms with respect to the power to weight ratio and also can keep joint forces even when the energy source (the hydraulic pump) does not work. In many cases of electric arms, the driving system (or the actuator dynamics) is simple and almost static, for example, the input torque (or velocity) is just proportional to the control input. On the other hand, in many cases of hydraulic arms, the driving system is complex and consists of compressible fluid systems, that is, nonlinear dynamical systems with unknown (or hard-to-be identified) parameters. To solve these problems, this chapter gives some results about modeling and control of hydraulic arms by applying and developing port-Hamiltonian systems and control theory.",

      "abstract": "This chapter shows that basic boundary control strategies for magnetohydrodynamics (MHD) can be derived from a formal system representation, called a port-Hamiltonian system (Van der Schaft and Maschke, 2002). The port-Hamiltonian formulation clarifies collocated input/output pairs used for stabilizing and assigning a global stable point. The controls called passivity-based controls (Arimoto, 1996; Ortega et al., 1998; Van der Schaft, 2000; Duindam et al., 2009) are simple and robust to disturbances. Moreover, port-Hamiltonian systems can be connected while keeping their consistency with respect to energy flows. Finally, we show that port-Hamiltonian systems can be used for boundary controls. In the future, this theory might be specialized, for instance, in order to control disruptions of Tokamak plasmas (Wesson, 2004; Pironti and Walker, 2005; Ariola and Pironti, 2008). This chapter emphasizes the versatility of control system representations.",

The finite or infinite-dimensional system under consideration possesses a Hamiltonian function, which represents an energy in the system and is conserved or dissipated along solutions. For infinite-dimensional systems this structure is preserved under suitable Galerkin discretization in space. The numerical scheme is energy-consistent in the sense that the Hamiltonian of the approximate solutions at time grid points behaves accordingly. This structure preservation property is achieved by specific design of a continuous Petrov–Galerkin (cPG) method in time. It coincides with standard cPG methods in special cases, in which the latter are energy-consistent. Examples of port-Hamiltonian ODEs and PDEs are presented to visualize the framework. In numerical experiments the energy consistency is verified and the convergence behavior is investigated.",

      "abstract": "In recent years, different strategies have been used to model HVDC systems. A usual strategy is to look for the models simplification (or linearization) to do a small-signal analysis. However, VSC-HVDC multiterminal links have intrinsically non-linear characteristics that need to be considered. Port-Hamiltonian (pH) systems provide a modeling methodology that allows incorporating the elements of the HVDC system in a modular way while explicitly providing the energy function, internal interconnection, and dissipation, which is helpful for analysis and control. This paper presents the modeling of a multiterminal HVDC network commonly used in the Electrical Power Systems literature from the pH perspective. It aims to use the pH structure to incorporate elements into the system while preserving its properties. Numerical simulations are carried out to show a comparison between the common model and the pH representation and it is shown that the latter reproduces the same dynamics of the former without loss of information but gaining in simplicity and structure.",

      "abstract": "In this work, the problem of additive perturbations is studied for a class of port Control Hamiltonian (PCH) systems. The considered class of Hamiltonian systems includes underactuated systems, which continue to be an important open study area. The starting point of the used methodology begins by considering that a previous tracking control has already made the equilibrium point of the error dynamic system asymptotically stable. The Integral Control (IC) reported in cite{ortega2012robust} and cite{ferguson2017integral} are implemented in the PCH class system so that it can reject the constant additive perturbations and conserves the Hamiltonian system structure. The results are compared and tested in a studied case with the system application of the Permanente Magnet Synchronous Motor (PMSM), and the MATLAB Simulink simulations obtained are exposed to compare the performance of both controls.",

The class of nonlinear Hamiltonian system is based on the structure of energy function where it is possible to pull the state apart at measured and unmeasured states which generates two interconnected Hamiltonian systems. Exploiting the properties of the class of nonlinear Hamiltonian systems a reduced order observation scheme is proposed. Finally the observer design proposed in this paper is evaluated in a magnetic levitator in order to prove its the convergence properties, also it is comparing the observer convergence characteristics and the observer performance among the observation schemes that are reported in the literature.",

The first step of the implemented methodology is to analyze the model structure and exploit its properties to design a speed tracking control. The mathematical model used to design the speed tracking control is in the dq reference frame, where the stator electrical sinusoidal signals are transformed into constant signals. The importance of the contribution is embedded in the system inversion, as the IM has an electrical subsystem not completely actuated, which makes the control scheme implementation for the IM not a trivial result. For illustration purposes, the numerical evaluation was done by a MATLAB Simulink simulation that shows that the designed control is able to follow variant speed references.",

The Port-Hamiltonian models for the two basic DC-DC converter topologies, Buck and Boost, are unified into a generalized structure.

Liquid piston (LP) technology for CAES is an alternative to other gas compression technologies developed to provide better heat transfer and thus increase energy efficiency. An energy-based model of a hydropneumatic accumulator using the LP gas compression in a port-Hamiltonian (pH) form is developed for control design. The bond graph framework is utilized to directly derive the equations in the pH form by exploiting the nonlinear fluid capacitance as a storage model. Nonlinearity is depicted analytically for a generalized polytropic process considering the ideal gas condition. The operation of the developed model is validated using MATLAB R2021b Simscape simulations.",

      "abstract": "In this work, we propose a power-balanced model of the full vocal apparatus, described by passive elementary components, the connection of which accounts for fluid-solid and fluid-fluid interactions. In the larynx, we consider a potential incompressible flow of an inviscid fluid between parallel moving walls whose dynamics is reduced to a mass-spring-damper oscillator equipped with an elastic cover. The vocal tract is represented by a macroscopic lumped parameter model derived for the irrotational flow of a compressible inviscid fluid with the simplest kinematics satisfying the boundary conditions. The assembly of elements admits a representation as a constrained global port-Hamiltonian system for which we propose simulations based on a projection method that preserves the power balance. Several numerical experiments show the ability of the model to reproduce a variety of regimes according to different configurations: non oscillating regimes (no phonation), periodic regimes (typical of healthy voice) and non-periodic oscillating regimes (typical of dysphonia). These simulations are used to sketch first cartographies of regimes with respect to con-trol parameters.",

In order to have a stable equilibrium at a prespecified state, the energy function is modified by adding storage elements to the BG such that the closedloop system energy has a minimum at that state. A new dissipation function is assigned changing the R-field and its interconnection with the rest of the Bond Graph. A desired power conserving interconnection structure is reached through the suitable insertion of power bonds among junctions. Energy shaping, interconnection and damping assignment are performed in a so called Target Bond Graph. The control law is determined by a set of partial differential equations derived from the plant and the Target Bond Graph.",

      "abstract": ": This paper describes a procedure to design a path following controller of port-Hamiltonian systems based on a training trajectory dataset. The trajectories are generated by human operations, and the training data consist of several trajectories with variations. Hence, we regard the trajectory as a stochastic process model. Then we design a deterministic controller for path following control from the model. In order to obtain reasonable design parameters for a path following controller from the training data, Bayesian inference is adopted in this paper. By using Bayesian inference, we estimate a probability density function of the desired trajectory. Moreover, not only the mean value of the trajectory but also the covariance matrix is acquired. A potential function for path following control is obtained from the probability density function. By incorporating the covariance information into the control system design, it is possible to create a potential function that takes into account uncertainty at each position on the trajectory, and it is expected to construct a control system that generates appropriate assist force for a human operator.",
