摘　　要：以新型AFFSFT电机为容错控制对象,针对该电机的单相故障设计了三相四桥臂的逆变器容错拓扑,详细论证了SVPWM容错控制算法的可行性,并基于AFFSFT电机的特殊结构,提出了励磁绕组辅助容错,以及特定转速区间降速运行的容错控制策略。在仿真测试的基础上,设计实验平台进行了控制实验验证,验证了该容错控制策略的可行性。With the new AFFSFT motor as the fault-tolerant control object,the three-phase four-bridge inverter fault-tolerant topology is designed for the single-phase fault of the motor. The feasibility of the SVPWM fault-tolerant control algorithm is demonstrated in detail. Based on the special structure of the AFFSFT motor,the field winding assisted fault tolerance and the fault-tolerant control strategy for the deceleration of the specific speed range are proposed. On the basis of the simulation tests,the experimental platform is designed,and the control experiment is carried out to verify the feasibility of the fault-tolerant control strategy.
