双Y连接的六相永磁电机单相故障的新型容错驱动控制

A New Fault Tolerant Drive and Control strategy with Double Y Connection for Six-phase Permanent-magnet Machine

电力作动系统取代液压作动是未来飞机的发展趋势之一,六相永磁电机被认为是应用前景较好的电机。本文提出了六相电机双Y连接的驱动控制系统故障后的一种新的驱动控制策略,将两个三相电路的中点连接在一起,以消除中线电流。仿真结果表明,这种方式可以实现六相电机容错驱动控制,具有其它方式没有的优点。

That electric actuation system replaces hydraulic pressure system is one trend of the next advanced plane. Six-phase permanent-magnet machine is considered a widely used one. A new fault tolerant drive and control strategy is put forward for a six-phase machine, in which two midpoints is connected together so as to eliminate midline current. Emulational result demonstrates that this method could achieve fault tolerant drive and control for a six-phase machine, and other advantages are also contained.
