摘要
在EMS型磁浮列车模块结构中,由于位移传感器与电磁力等效作用点偏移一定距离,传感器检测的位移信号并不是所要控制的电磁铁位移值,传感器信号之间具有耦合关系。本文对这种耦合关系进行了定性和定量分析,以青城山示范线磁浮车为例,计算和分析了不同情况下的耦合强度,提出了降低耦合的方法,为控制系统的设计提供了依据。
In the modular of EMS maglev, displacement sensor signals are coupled because of the interval between the sensor and equivalent action-point of the attractive force. The values detected by sensors are not the real magnet displacements. The coupling relation of sensor signals is described qualitatively and quantitatively in this paper, taking the vehicle for the Qingchengshan test line as an example. And the solution to reducing the coupling strength is proposed for the control system design.
