无传感器永磁同步电机驱动中常见电气故障与传感器故障的容错控制

Conventional sensorless control can hardly estimate the rotor position of faulty drives, which will cause the breakdown of the sensorless permanent-magnet synchronous motor (PMSM) drives in short time. In this article, a fault-tolerant (FT) control scheme is proposed for common electrical faults and sensor faults in the sensorless PMSM drive without using any auxiliary facilities. In the proposed ...
