摘　　要：在分析双绕组三相永磁容错电机基本结构的基础上,讨论了电机在开路和短路故障情况下的转矩脉动和铜耗。详细论述了加倍增加对应相电流容错控制策略、最优转矩容错控制策略和电流矢量容错控制策略的实现方法。通过数学计算和仿真比较分析了3种容错控制策略的性能和优缺点。硬件实验结果验证了所提出的电流矢量容错控制策略的正确性和可行性。On the basis of analyzing the principle structure of the dual-winding three-phase fault tolerantmotor, this paper discusses the torque ripples and copper loss under motor open-circuit and short-circuitconditions. Then the doubling current fault-tolerant strategy, the optimal torque control, and the current vectorfault-tolerant control are discussed in detail. The characteristics of these fault-tolerant control strategies arediscussed and analyzed by calculation and simulation. Finally, the correctness of the proposed current vectorfault-tolerant control is verified by the hardware experiment setup under healthy and open-circuit conditions.
