Minling Feng, Kunpeng Wu, Shaofeng Lu

摘要:

在现代轨道交通中,训练节能控制(EETC)是指在各种运营和牵引约束条件下,以最小的能量消耗为目标,寻求最优的训练速度轨迹或控制策略。本文提出了一种基于凸优化的EETC模型,使该模型能用凸优化算法快速求解。通过与混合整数线性规划(MILP)和Radau伪谱法(RPM)等主流数学规划方法的比较,验证了该方法的高计算效率和鲁棒性.基于凸优化的特点,该方法在计算效率方面具有明显的优势,在各种轨道交通自动训练控制系统的在线应用中具有广阔的应用前景。

英文摘要:

In modern rail transportation, energy-efficient train control (EETC) is concerned with the optimal train speed trajectory or control strategies to achieve the minimum energy cost under various operation and traction constraints. This paper proposes an EETC model based on convex optimization so that the model can be rapidly solved by convex optimization algorithms. The high computational efficiency and robustness of the convex model can be verified by comparing the results achieved by the method proposed by this paper and other mainstream mathematical programming methods including mixed-integer linear programming (MILP) and Radau pseudospectral method (RPM). Based on the characteristics of convex optimization, the proposed method boasts more significant advantages over its counterparts in terms of computational efficiency in the promising online applications for automatic train control systems of various types of rail transportation.
