基于PID算法ATO系统的仿真研究

基于现有列车运动模型,设计了列车速度闭环仿真模型,其中控制器采用PID控制算法,当系统输入波浪形V-S曲线时,在PID控制器控制参数设置恰当的情况下,系统输出的V-S曲线具有较为满意的跟随性,在输出的加速度曲线中在列车的启动阶段和中间速度波动阶段会有尖峰波动现象。针对基于PID控制算法的ATO系统出现的问题进行了分析。

Simulation research on ATO System based on PID Algorithm

The thesis reviewed the development of the Automatic Train Operation(ATO) System and designed the train speed closed-loop simulation model, in which the PID Algorithm was used, when the V-S curve was input to the System in the PID controller, the output was satisfactory followed the start-up phase of the train. During the intermediate speed fluctuation stage, there would be a spike wave phenomena in the output of the acceleration curve. Problems of ATO System based on PID Algorithm was analyzed.
