摘　　要：针对一种用四极电磁铁代替U型磁铁构建的三自由度电磁悬浮系统,提出了一种新的控制方法。这种控制方法可以实现低功耗控制,并且不需要位移传感器。In this paper,a control method was proposed for 3 degrees of freedom electromagnetic levitation system with permanent magnet in which the U-type magnet was replaced by a 4-pole type yoke hybrid electromagnet.And the low consumed power control without gap sensors can be realized by this method.

关 键 词：电磁悬浮系统 低功耗控制 无位移传感器 非线性模型
