A Model Predictive Control for Event-Triggered Three-Phase Vienna Rectifiers

摘要

A model predictive control based on event-trigger (ETMPC) is presented for three-phase Vienna rectifier in this paper. The event-triggered condition of the ETMPC for three-phase Vienna rectifier is derived, which means the MPC scheme is triggered only when the system state exceeds the condition; otherwise, the MPC scheme is suspended and the control signal is held as the last moment. Compared to the conventional MPC with finite control set (FCS-MPC), the satisfactory regulation performance of the Vienna rectifier is achieved by the ETMPC method with less computation burden and switching actions. From the comparison with the conventional MPC method, the effectiveness and correctness of the proposed ETMPC method is demonstrated by the results of simulation experiments.
