摘　　要：在悬浮控制系统设计中,通常用到悬浮间隙的变化速度,如何获取这一信号是一个非常重要的问题。以单电磁铁为对象,根据悬浮系统的模型,提出了一种通过互补滤波器获得速度的方法;详细分析了不同的速度获取方式在考虑轨道随机扰动和列车运行于竖曲线段以及考虑轨道弹性等几种情况下对系统的影响。仿真结果表明,该方法能很好地实现常规方法的性能折衷,为克服轨道扰动和解决车轨共振问题提供了新的思路。The problem to obtain the signal of the velocity of clearance in designing the suspension control system is discussed. To the single electro-magnet, the modal of the suspension system is derived, and a method to get the velocity by the complementary filters is given. The influence on the system due to different ways to get the velocity is analysed particularly under the conditions of considering the random disturbance of the roadway and when the train running on the transition curve as well as considering the elasticity of the track. The simulate results indicate thai this method can split the difference of the performance by the common way, thereby provide a new idea to overeome the perturbation of the track and the coupled vibration problem between the rain and the trace.
