基于Smith原理的车辆牵引变速控制

Train Change-speed Control Based on Smith Principle

介绍了城市轨道列车自动变速控制的一种方法———Smith重叠控制 .具体结合地铁车辆牵引的模型 ,详细分析并推导了控制系统的模型 ,导出了Smith重叠控制的参数 .经仿真实验验证 ,该控制方法具有无超调及快速响应的良好动态性能 ,可满足城市轨道列车高性能的变速控制的要求 ,工程实时控制实现也比较方便 ,是一种实用的城市轨道列车变速控制的工程方法 .

This paper introduces one of the methods——Smith overlapped control method, which is used in the automatic city railway train change_speed control,combining one kind of underway train tractive model,labor,the paper deduces the transfer function of the control system,and obtained the parameters of Smith control method,by experiments.It proves no overshoot and responds quickly,achieving the favorable dynamic performance.It can meet the require of high performance in trailway train change speed control,and it is of convenience to implement in real time control of the project and is one of the practical methods in project.
