基于混杂系统理论的CT CS-3级列控系统建模与仿真

摘要

列车运行控制系统（列控系统）显著表现出离散和连续同时存在的混杂特征。建立合适的模型无论对列控系统的前期设计还是后期分析都具有重要意义。针对列控系统的混合性，提出用混合自动机对列控系统进行建模，在Matlab环境下用Simulink和Stateflow对建立的自动机模型进行仿真分析，并以两车追踪场景为例对整个过程进行了介绍。仿真结果表明了该方法的有效性和可行性。%Train control system apparently exhibits its hybrid character of discrete and continuous characters coexisting.To build a proper model has the significance to the stages of both pre-design and post-analysis in regard to the train control system.Considering the hybrid property of the train control system,in this paper we propose to model the system with hybrid automaton,and carry out the simulative analysis on automaton model using Simulink and Stateflow tools in Matlab environment.Besides,the scene of two trains tracking is taken for the example to describe the whole process of hybrid automaton modelling.Simulation results also illustrate the effectiveness and feasibility of this method.
