摘    要:针对站间线路存在不同限速的情况,提出一种运行时间优化分配方法。根据影响速度曲线节能优化的限速划分了优化区间,建立每个优化区间的能耗—时间函数,借助拉格朗日法建立增广目标函数,通过拟牛顿法迭代得到站间运行时间优化分配结果,采用Matlab进行仿真。当区间的线路限速数量和限速值不同时,也可以通过该方法进行站间运行时间的优化分配。最后在基于CMC芯片的硬件环境下进行了测试。

关 键 词:列车控制    节能优化    时间分配    CMC芯片

Abstract:This article proposed an optimization method for inter-station running time distribution of a train, as the line speed between two stations was limited. The inter-station line could be divided into several intervals based on the number and the values of the speed limits which influence the speed profile directly. The Energy-Time function of each interval could be calculated through function fitting. The article established an augmented objective function via Lagrange multiplier. The simulation was taken by Matlab, and the optimization results for inter-station running time distribution were obtained by the Quasi-Newton method. This method could be applied to lines with different speed limits if the Energy-Time function of every interval could be obtained. This method was tested based on the hardware environment of the CMC chip .
