EMS型高速磁浮列车自适应导向控制器设计

EMS型高速磁浮列车导向系统的工作条件变化范围大,采用一般方法设计的控制器无法在整个工作范围内保持一致的控制性能。为了解决这个问题,研究了自适应导向控制器的设计方法。首先,建立了导向系统的数学模型,通过设计电流环使模型降阶;并分析了导向系统参数的变化原因及特性,在此基础上采用自校正的自适应控制理论,设计了参数自适应的导向控制器。仿真结果表明,该控制器较好地解决了导向系统在整个工作范围内特性不一致的问题。

Adaptive Controller Design of Guidance System of EMS High Speed Maglev Train

To the problems that the working conditions of the guidance system of EMS high speed maglev train varies in a extensive range,and the controlllers by normal designing methods can not keep consistent performance in all situations,the adaptive guidance control design method is discussed.The model of the guidance system on EMS high speed maglev train is set up,and the current loop is designed to reduce the model degree.The reason and the characteristic of the guidance system parameter changing are analyzed.Based on that,using the self tracking controller design method,an adaptive guidance controller is designed.The simulation result shows that the presented controller can solve the problem that the guidance system working characteristic is unlike under different working conditions.
