解耦分析磁悬浮列车的悬浮控制问题

Analysis of Suspension Control of Maglev Train with Decoupling Method

磁悬浮列车作为一种新型地面交通工具，已经在实践中得到了成功的应用。对于电磁吸引悬浮系统，由于其系统具有的非线性和不稳定性，需要通过模拟控制器或数字控制器对其进行稳定控制。通过解耦，磁浮列车的悬浮控制问题可以简化为单个电磁铁的悬浮控制问题。这样，对单电磁铁悬浮控制系统的分析设计就变得十分关键了。

As a new-style of vehicle on the land,maglev train has been put into practice successfully.Due to the inherent nonlinearity and instabililty of the electromagnetic attraction Suspension system （EMS）,controlling its stability is accomplished either through analog controllers or through digital controllers.By decoupling,the magnetic suspension control of the maglev train can be simplified as the suspension control of single electromagnet,Thus,the analysis and design of the suspension control system of single electromagnet have become extremely essential.
