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

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.
