The invention relates to a high-speed train optimal traction coordination method based on dynamic average consistency, and belongs to the field of high-speed train operation control. The method comprises the steps that a high-speed train with at least two traction power units is considered, and a traction power coordinated optimization problem of the high-speed train is established according to the running state of each traction power unit; secondly, converting a traction power coordination optimization problem into a dynamic average consistency problem by utilizing optimal solution characteristics; and solving the optimal traction force of each traction power unit of the high-speed train in a distributed manner based on a coordinated optimization algorithm of elastic fixed time dynamic average consistency. According to the invention, global information collection and processing of the control center are not needed, and single-node faults of the control center are avoided; the optimal solution can be tracked within the preset fixed time, and the rapid and high-precision control performance requirement of the train can be met; and normal operation under network attack can be realized, and safe and stable operation of the high-speed train is ensured.

    本发明涉及一种基于动态平均一致性的高速列车最优牵引协调方法,属于高速列车运行控制领域。该方法包括:考虑一辆具有不少于2个牵引动力单元的高速列车,根据每个牵引动力单元的运行状态,建立高速列车的牵引动力协调优化问题;然后利用最优解特征,将牵引动力协调优化问题转化为动态平均一致性问题;基于弹性固定时间动态平均一致性的协调优化算法分布式地求取高速列车每个牵引动力单元的最优牵引力。本发明无需控制中心的全局信息收集和处理,避免了控制中心的单节点故障;可在预设固定时间内跟踪最优解,可满足列车的快速高精度控制性能要求;可在网络攻击下正常运行,保证高速列车的安全稳定运行。
