摘要
针对高速列车黏着控制提出一种最优蠕滑辨识方法,通过仿真分析验证该方法的有效性。通过捕捉瞬态控制和稳态控制切换时的蠕滑率作为控制基准值,以模糊控制方式对控制基准值进行调节,实时辨识轨面最优蠕滑率。该方法以最优蠕滑率为控制目标达到获取最优黏着控制效果,实现了最大黏着系数利用、提升牵引力发挥稳定性的目的,为黏着控制在高速列车领域的应用提供了指导。
An optimal creep identification method was proposed for adhesion control of high-speed train, and the effectiveness of the method was verified by simulation analysis. Through the switching process of transient and steady-state control, the creep rate at the time of switching was captured as the control reference value, and the control reference value was adjusted by the fuzzy control method to identify the optimal creep rate of the track surface in real time. The method took the optimal creep rate as the control objective to obtain the optimal adhesion control effect, realized the utilization of adhesion coefficient, improved the stability of traction, and provided guidance for the application of adhesion control in the field of high-speed train.
