Modeling and System Identification of the Braking System of Urban Rail Vehicles

列车制动模型是设计ATO精确停车控制策略的依据。本文通过分析城轨列车制动系统的构成、特性及其和驾驶员的接口,从面向控制的角度提出适合控制器设计的制动模型以及模型参数的辨识方法。现场实验表明:该模型能够较好描述城轨列车制动系统的动态特性,并且基于该模型的自动停车控制系统在实验中也取得了满意的性能。

The braking model of the train is crucial for design of ATO control law for train stop.In this paper,we propose a braking model and a method for identifying its parameters after reviewing the composition,characteristics and interface of the braking system of the urban rail train.The model is validated with data from field experiments.Its applicability for the control purpose has been demonstrated by the performance of an automatic stopping controller designed on the basis of the proposed braking model.
