摘要
驱动系统中的功率器件经常会发生开路或短路故障,电机定子绕组也会发生开路故障。这些故障会严重影响永磁电动机系统正常工作,对整个系统的安全性和稳定性造成严重影响。分析永磁电机驱动系统的容错控制策略,并且对各容错策略进行分析比较。展望了永磁电动机容错策略的发展趋势。
Due to power electronic device open or short circuit fault occurs on the inverter, and motor stator winding often opens, these faults may cause serious effects on normal running of the drive system. The fault tolerant strategies of the drive system for permanent magnet （PM） motor are analyzed, the various strategies are compared, and the trend of fault tolerant strategies for PM motor is also given.
