摘　　要：六相永磁同步电机及其驱动系统具有诸多优点,然而其相间的耦合较为严重,采用矢量控制时d-q电流存在扰动,为了减小扰动现象,文章提出基于电压补偿的控制策略,与六相永磁同步电机三电平变频调速系统相结合,进行仿真论证。首先建立六相永磁同步电机双d-q模型,设计基于电压补偿的控制策略,与不进行补偿的控制策略进行对比分析,仿真研究结果论证了基于电压补偿的控制策略优于无补偿的控制策略。基于电压补偿的控制策略,对六相永磁同步电机三电平变频驱动与两电平变频驱动的性能进行了仿真分析,仿真结果表明,六相永磁同步电机三电平变频驱动系统较两电平变频驱动系统的谐波畸变率更低,转矩的抖动更小。基于电压补偿的六相永磁同步电机三电平变频驱动具有更好的工程使用价值。For different kinds of advantages,the study of six-phase PMSM driven by inverter has significant importance.However,the six phase permanent magnet synchronous motor coupled with serious d-q current disturbances.In order to reduce the disturbance phenomenon,a control strategy based on voltage compensation is presented in this paper,which is combined with three level variable frequency speed control system of six phase permanent magnet synchronous motor.In this paper,the six phase permanent magnet synchronous motor with double d-q model has been established.The control strategy based on voltage compensation is compared with the control strategy without compensation.The simulation results demonstrate that the control strategy based on voltage compensation is superior to the control strategy without compensation.In addition,Based on the voltage compensation control strategy,six phase permanent magnet synchronous motor with three level inverter is compared with the two level variable frequency drive system.The simulation results show that the six phase permanent magnet synchronous motor with three level inverter has preference to the two level variable frequency drive system,whose harmonic distortion rate is lower,the smaller torque ripple.The six phase permanent magnet synchronous motor with three level inverter based on voltage compensation has better engineering application value.
