Short-Circuit Fault-Tolerant Operation of Dual-Winding Permanent-Magnet Motor Under the Four-Quadrant Condition

In this paper, a short-circuit fault-tolerant operation control strategy of dual-winding permanent-magnet motor (DWPMM) under the four-quadrant condition for electrical flight surface actuator application is proposed and investigated. By the comparative analysis of the current fault-tolerant permanent-magnet motor drive system, it can be concluded that the DWPMM drive system is suitable for electrical flight surface actuator application. However, the current DWPMM drive system lacks the research on short-circuit fault-tolerant operation under the four-quadrant condition. Then, the electrical flight surface actuator system based on the DWPMM and short-circuit fault-tolerant operation control strategy under the four-quadrant condition is proposed and investigated. The experimental results show that the electrical flight surface actuator system based on the DWPMM can achieve the high performance of the four-quadrant fault-tolerant control with short-circuit fault under the four-quadrant operational condition.
