Research on Control of Magnetic Suspension for the Rail Transit

磁悬浮工程是一项新兴技术,悬浮控制技术是磁悬浮列车的核心技术之一,该课题主要以悬浮控制系统为控制对象,建立磁悬浮列车悬浮气隙控制的无静差系统。采用 MATLAB 软件中的 SIMULINK 控制工具箱对悬浮控制系统进行动态仿真。实验结果表明,系统的跟随性能和抗干扰性能好,突加负载扰动和卸载时恢复时间短,动态降落小。可以满足系统的要求。

Magnet suspension engineering is a up-to-date technology. Suspension control technique is one of the central techniques of the magnet suspended train. This thesis regarding the suspension control system as a control object sets up a non-static-error suspending airgap control system of the magnet suspended train. Make use of the SIMULINK control tool in MATLAB software to dynamically simulate the suspension control system. The experimental result shows that the following performance and disturbance resistance performance of the system are good, the recovery, time of accidentally loading and unloadind are short, dynamic speed drop is small, and all those can satisfy the requirments of the system.
