摘　　要：为获得电驱动系统的高可靠性,对六相十极永磁容错电机及其驱动器系统进行了研究。在永磁容错电机的结构特点及数学模型的基础上,分析了电机正常运行与故障状态时的直接转矩控制策略,从而提出基于三相四桥臂的直接转矩控制算法的容错控制策略。实验结果表明:系统在故障态可以获得与正常态相媲美的控制效果,转速、转矩和定子磁链几乎无波动,实现了容错控制,验证了基于直接转矩控制的容错控制算法的可行性。In order to meet the requirement of aviation power actuator systems＇ high reliability,the topology of a six-phase ten- pole fault tolerant permanent magnet motor drive system was introduced. Based on the introduction of its structural features and the mathematical model,the direct torque control strategy when motor under normal and fault conditions were analyzed. The fault tolerant control strategy under direct torque control system based on the three- phase four- leg was proposed. Experimental results show that when the system was in fault condition,compared with the normal state,the speed ripple,torque ripple and the stator flux chain ripple were almost unchanged,and the fault tolerant control strategy under direct torque control system was verified practicability..
