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.
