摘　　要：针对常规的模型预测控制(MPC)策略存在电流纹波较大、缺乏严格的理论基础等问题,提出了一种考虑直流电压脉动的可视化分析方法,以评估三相四开关逆变器驱动永磁同步电机(PMSM)系统常规多矢量MPC策略的有效性。详细介绍了基于可视化分析的常规多矢量MPC策略有效性的证明方法,并根据该方法证明了三矢量MPC策略比单矢量MPC策略具有更小的电流控制误差和纹波。然而,该分析结果也表明,在整个电压矢量平面内,常规三矢量MPC策略并没有完全优于常规双矢量MPC策略。为此,根据该分析结果提出了一种混合多矢量MPC策略,通过融合常规双矢量和三矢量MPC策略,进一步降低了电流控制误差和纹波。最后,对比实验研究验证了所提混合多矢量MPC策略的有效性。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.
