短定子磁浮列车基于悬浮间隙实现测速和定位的算法仿真及应用

Algorithm Simulation and Its Application of Speed Measurement and Positioning Based on Suspension Gap for Short Stator Maglev Trains

短定子磁浮列车测速和定位技术实现方式与传统轮轨不同,目前有多种技术实现方式,但都需要在磁浮列车上设置测速和定位设备或系统,且与悬浮控制系统相互独立,但悬浮控制系统对速度信号和位置信号又有一定的依赖性。因此,设计了一种基于悬浮间隙实现测速和定位的算法,并通过仿真达到算法设计预期目的,最后通过编程将算法嵌入磁浮列车的悬浮控制系统硬件平台,实现测速和定位的算法应用,测速和定位信号完全集成于悬浮控制系统中,摆脱悬浮控制系统对外置测速定位系统的依赖,提升磁浮列车在轨道交通市场的竞争力。

The implementation method of speed measurement and positioning technology for short stator maglev trains is different from traditional wheel rail systems.Currently,there are multiple technical methods available,but all require the installation of positioning and speed measurement equipment or systems on maglev trains,which are independent of the suspension control system.However,due to the fact that the suspension control system also has dependence on speed and position signals,an algorithm has been designed for speed measurement and positioning based on suspension gap,with the expected purpose of algorithm design achieved through simulation.Finally,the algorithm is embedded into the hardware platform of the maglev train’s suspension control system through programming,thus realizing the application of speed measurement and positioning algorithms,The speed measurement and positioning signals are fully integrated into the suspension control system,eliminating the dependence of the suspension control system on external speed measurement and positioning systems,and enhancing the competitiveness of maglev trains in the rail transit market.
