After a detailed analysis of the forces in subway train's running, the dynamics mathematical model of subway train is constructed; the eventbased control technology is adopted to solve the controlling of subway, the velocity and acceleration function with respect to the distance are deduced by introducing the action reference variable in the control problem which the object is to minimize the running time. The running scheme can be programmed in realtime, the delay caused by uncertain events is avoided. So it offers a new way for the metro research.
分析了地铁列车运行过程中的受力情况,建立了地铁列车的力学模型;将基于事件的控制技术应用到地铁列车的控制中,通过引入运动参考变量,求出在以站间最小运行时间为最终目标的列车控制中,列车速度、加速度等关于列车运行距离的函数表达式,从而可以根据列车走行距离来实时调整和规划地铁的运行规律,避免人为因素或不确定性因素导致的列车运行晚点,为研究地铁列车的规划提供了一种新的方法。
