Research on MRSMC for Three-phase Grid-Connected Inverter

Abstract

A model reference sliding mode control(MRSMC) is proposed for the three-phase grid-connected inverter. Firstly, the phase voltage and current of the grid are set as the objective function. The corresponding state equations can be derived for the grid voltage and current. Then, a feedforward control scheme is designed to achieve current decouple. Moreover, the Lyapunov stability theorem is used to verify the stability of the system with the decoupled control law. The effectiveness of the proposed method is verified by the simulated results.
