摘　　要：对矢量控制九相定子36槽/转子34极磁通切换永磁(flux-switching permanent magnet,FSPM)电机驱动系统中一相断路故障工况进行研究。单相故障时,根据转矩电流分量不变及定子铜耗方程,提出了3种谐波电流注入模式下无扰运行的容错控制策略,即在容错运行时分别注入3次,3、5次以及3、5、7次谐波电流,进而获得铜耗最小优化目标的容错电流通用在线生成方法。仿真分析和原理样机容错实验结果,证明了所提方案可以减小定子绕组断路故障引起的转矩脉动,使九相FSPM电机在故障状态下的运行性能得到明显改善,有效提高调速系统的可靠性。An investigation of open-circuit fault condition for vector-controlled nine phase 34-rotor-pole and 36-stator-slot flux-switching permanent magnet（FSPM） machine drive systems was done. In order to achieve the invariant in the torque-producing current and minimum stator copper losses, three approaches to fault-tolerant control based on the harmonic current injection were proposed to achieve the disturbance-free operation. The fault-tolerant currents can be online calculated by deducing the third, the fifth and the seventh harmonic currents in the copper loss optimization process. Finally, a nine-phase FSPM motor was prototyped for verification. Both simulations and experimental results are presented, verifying the proposed fault-tolerant control strategy.
