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.

四象限条件下双绕组永磁电机的短路容错运行

本文提出并研究了一种四象限条件下双绕组永磁电机（DWPMM）短路容错运行控制策略，适用于电动飞行面执行器。通过对目前容错永磁电机驱动系统的对比分析，可以得出结论，DWPMM驱动系统适用于电动飞行面执行器应用。然而，目前的DWPMM驱动系统缺乏对四象限条件下短路容错运行的研究。然后，提出并研究了基于DWPMM和四象限条件下短路容错运行控制策略的电动飞行面执行器系统。
