Abstract

The existed control methods for Port-Hamiltonian (PH) systems subjected to actuator saturation (AS) were only beneficial for the Hamiltonian function having a local minimum at its equilibrium point. Once the Hamiltonian function do not have that feature or is not positive definite, the existed methods are ineffective. To improve the defect of existed methods, this paper investigates the stabilization of PH systems subjected to AS via energy-shaped and Hoo control. 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.
