摘　　要：为弥补模糊PID控制在ATO(列车自动运行)系统中无法自动靠站等问题,将切换控制系统理念引入ATO中。针对A型地铁的受力情况,建立其运动学模型,并设计简单的运行路线。使用MATLAB对列车的运行过程进行仿真,在得出的运行特性图的基础上,建立列车的切换系统各工况的子空间模型及切换控制策略。为验证上述切换策略的有效性,对列车在终点路段的切换过程进行仿真得出列车能够稳定停车靠站的结论。最后,加入外界扰动的情况下,对列车危险路段的切换过程进行仿真,验证上述切换策略的有限时间稳定性。In order to make up the shortcomings of fuzzy PID control in ATO system, the idea of switching control system was introduced into ATO. In this paper, the kinematics model of a-type subway was established and a simple running route was designed. MATLAB was used to simulate the running process of the train. On the basis of the running characteristic diagram obtained, the subspace model and the switching control strategy for each working condition of the train switching system were established. In order to verify the effectiveness of the switching strategy, the simulation of the switching process of the train in the end section shows that the train can stop and stop stably. Finally, with the addition of external disturbances, the switching process of dangerous sections of the train is simulated to verify the time-limited stability of the switching strategy.
