A Novel Finite-Control-Set Model-Free Predictive Current Control for PMSM Drives with Event Triggering Mechanism

This paper proposes a novel finite-control-set model-free predictive current control (FCS-MFPCC) for permanent magnet synchronous machine (PMSM) drives. Different to the existing FCS-MFPCC strategies, the proposed strategy is designed based on the sliding-mode (SM) control theory, holding the merits of parameter-independence and low computation burden. Furthermore, the event triggering (ET) mechanism is introduced to the proposed FCS-MFPCC by proposing a combined triggering condition. In this way, not only the current errors can be regulated within a preset range but also the SM existence condition can be maintained anytime. Finally, the comparatively simulated results are given to validate the effectiveness of the proposed strategy.
