摘　　要：过去的永磁同步电动机采用六边形磁通控制或六区圆形间磁链控制间隔,从而导致转矩脉动过大等缺点;设计了一种基于矢量细分的双控制器永磁同步电机直接转矩控制系统;设计的矢量细分的控制策略是将传统意义上的六电压矢量和六个磁链扇区细分为多个电压矢量和磁链扇区,并制定相应的开关表;通过Matlab的仿真结果来证明矢量细分的永磁同步电机直接转矩控制策略的可行性。Past permanent magnet synchronous motor using hexagonal flux control or six intervals flux control interval which results in torque ripple and other shortcomings. In this paper,the dual-controller permanent magnet synchronous motor direct torque control system based on vector subdivision is designed. This design of the vector control strategy is to segment the six voltage vector in tradition and is subdivided into six sectors flux multiple voltage vector and flux sector,and appropriate switch table is developed. Matlab simulation results prove that permanent magnet synchronous motor direct torque control strategy based on vector subdivision is feasible.
