摘　　要：为进一步提高多相电机系统的容错能力,该文提出一种3×5 相永磁同步电机(PMSM),该电机绕组采用星形联结且三个中性点彼此独立结构,并对一相开路故障的五相绕组直接进行不降额的解耦控制与电流最优的滞环容错控制。首先,分析3×5 相PMSM 定子电压与磁链方程,并建立三dq 轴矢量控制模型;其次,在一相绕组开路的容错运行条件下,比较五相六桥臂空间矢量脉宽调制(SVPWM)容错控制与电流滞环容错控制的实现方式,并对两者的相电流进行谐波分析;最后,搭建基于FPGA 的十五相永磁同步电机驱动控制实验平台,解决了多路PWM 输出同步与PWM 输出管脚数量受限的问题。仿真和实验结果证明了所建立的电机控制模型与容错控制理论分析的正确性。In order to further improve the fault tolerance of multiphase motor systems, a starconnected 3×5 phase permanent magnet synchronous motor with three neutral points independent of each other was proposed. The decoupling control and the current optimal hysteresis fault-tolerant control were performed directly on the five-phase winding with one-phase open-circuit fault. Firstly, the stator voltage and flux equation of 3×5 phase PMSM were analyzed and the three dq axis vector control model was established. Secondly, Under the fault-tolerant condition of one phase open circuit, the implementation between the five-phase six-bridge arm space vector pulse width modulation (SVPWM) control and current hysteresis control was compared, and the phase current harmonics of the two were analyzed. Finally, FPGA-based fifteen-phase PMSM drive control and fault-tolerance experimental platform was established to solve multiple PWM output synchronization and port limitation issues. Simulation and experimental results verify the correctness of the established motor control model and theoretical analysis of fault-tolerant control.
