摘要：

Aiming at the problems of large current ripple and lack of strict theoretical basis in conventional model predictive control (MPC) strategy, a visualization analysis method considering DC voltage pulsation was proposed to evaluate effectiveness of the conventional multi-vector MPC strategy for permanent magnet synchronous motor (PMSM) system driven by three-phase four-switch inverter. The effectiveness verification method of the conventional multi-vector MPC strategy based on visualization analysis was introduced in detail. According to this method, it was proved that the current control error and ripple of three-vector MPC are smaller than that of single-vector MPC strategy. However, the analysis results also show that the conventional three-vector MPC strategy is not completely superior to the conventional two-vector MPC strategy in the whole voltage vector plane. Therefore, according to the analysis results, a hybrid multi-vector MPC strategy was proposed, which further reduces the current control error and ripple by combining the conventional two-vector and three-vector MPC strategies. Finally, effectiveness of the proposed hybrid multi-vector MPC strategy is verified by comparative experimental studies. © 2025 Editorial Department of Electric Machines and Control.
