Port-Controlled Hamiltonian and Energy-Shaping Based Current Control Scheme for Grid-Connected Inverter

Authors

Abstract

A novel current controlled scheme based on port-controlled Hamiltonian and energy-shaping control method has been proposed for the grid-connected inverter. 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.
