Abstract:A design method of three-phase four-wire inverter based on modified Repetitive Controller (MRC) is presented, which can effectively suppress the disturbance of output voltage caused by nonlinear load.In order to solve the contradiction between the stability and the control performance of the repetitive controller, a dOF - zero phase filter is added in the compensation link.Taking the error attenuation rate and the complexity of the filter as the optimization objectives, and the robust stability of the system as the constraint, the optimal design of the zero phase filter based on particle swarm optimization method is presented, and the MRC based on the robust optimized zero phase filter is constructed.The optimal design of the MRC takes into account the unmodeled error of the system, which is robust and convenient for industrial application.The three-phase four-line inverter uses carrier modulation to maximize the use of DC voltage without complex data processing and is easy to implement.Theoretical analysis and experimental results prove the validity and feasibility of MRC and its optimization design method for three-phase four-wire inverter.
