Continuous Control Set Model Predictive Control (CCS-MPC) of A Three-Phase Rectifier

Abstract

The rectifier is one of the popular power electronic converters in industrial applications such as in the railway and power supply systems. In this paper, a three-phase controllable rectifier is considered and the continuous control set model predictive controller (CCS-MPC) is designed. By considering system dynamic response, the proper criteria to select the sampling time, prediction horizon and control horizon is proposed. By using these criteria, the tradeoff between computational burden and system performance dynamic is made. When using the CCS-MPC controller, the rectifier and grid performance such as total harmonic distribution (THD) and power factor (PF) have acceptable value. The simulation results are validated by using MATLAB/SIMULINK software.
