针对磁浮列车过弯的鲁棒控制方法

Robust control for maglev train when passing the curve

考虑磁悬浮列车通过弯道时电磁铁上表面与轨道下表面发生错位,相对磁极面积减少情况下的控制问题,将相对磁极面积视为不确定性参数,引入相对磁极面积摄动,再针对磁悬浮非线性系统设计动态输出反馈控制器,并将控制器设计问题转换为H∞控制问题,使得系统不管电磁铁与轨道之间如何错位,只要没有超出电磁铁的承载力,就可以稳定悬浮,顺利通过弯道。

When the maglev train passes the curve,lateral displacement between magnet and track happens,and the area of magnetic pole decreases.Considering the area of magnetic pole as an uncertainty parameter,the alteration of the parameter is presented.Then dynamic output feedback controller of maglev system is worked out,and the controller designing is transferred to design an H∞ controller.The suspension can keep stable until the bearing of the weight goes beyond,and the maglev train can pass the curve successfully.
