摘　　要：在磁悬浮列车运行过程中,轨道的不平顺对悬浮系统有很重要的影响。如何克服轨道的干扰是悬浮控制系统设计中一个很重要的问题。基于互补滤波器的思想,提出了一种双位置环反馈的控制方法。通过建立以单电磁铁为对象悬浮系统的数学模型,设计适当的滤波器和控制器,实现了悬浮控制系统的稳定工作,进行了仿真验证。理论分析和仿真结果表明该方法与传统的单位置环反馈控制相比更能够有效地实现悬浮系统对轨道表面低频曲面变化的跟踪,同时对轨道不规则变化造成的高频抖动有较强的抑制能力,为解决轨道的干扰问题提供了一种很好的思路。When the maglev train is running,the suspension system is influenced by the variation of the track to a great extent.How to overcome this disturbance of the track is an important problem in designing the maglev control system.In this paper,based on the idea of the complementary filters,a method of dual position feedback control is given.By establishing the model of the single electro-magnet suspension system and designing proper filters and controller,the suspension system works stably,and the simulating experiment is carried out.The simulation results indicate that compared with the traditional single position loop feedback control,the suspension system using this control method can follow the guideway profile at lower frequencies effectively,while at higher frequencies it can restrain the oscillations caused by guideway irregularities efficiently,and it provides a good idea for solving the problem of the disturbance from the track.
