基于Matlab的地铁系统建模与仿真

The Modeling and Simulation of the Metro System Based on Matlab

为深入研究地铁,有必要对地铁牵引供电系统及车辆进行仿真研究。通过模拟城市地铁系统实际构成与电气参数,根据地铁列车运行原理,运用Matlab/Simulink工具包提出了数学与物理模型相结合的建模方法,建立了轨道交通供电系统与机车模型。仿真得出了地铁机车运行过程中随时间、机车速度及位移变化的功率、电流、电网电压等电气参量波形。仿真结果与实测曲线相一致,表明该仿真模型真实可信。

In order to establish a basic foundation for the further research of the metro, building the computer simulation model of the subway is a prompt and convenient method. By means of imitating the construction of the actual city metro and the electrical parameter and according to the operating principle of it, the electrical value such as power, current and network voltage is achieved as the time, the speed and the position of the train varies through simulation in combination of math and physical modeling with the help of Simulink tool of the Matlab.
