The invention discloses a high-speed train anti-skid control method with input time lag compensation and actuator fault tolerance. The high-speed train anti-skid control method specifically comprises the steps that a train adhesion dynamic model with input time lag and actuator fault tolerance is established for a train needing to achieve an anti-skid control target; processing the train model by using a linearization technology to obtain a train cruise operation stage approximation model, further carrying out cruise stage controller design, and obtaining a corresponding time-lag stability upper bound at the same time; and taking the obtained time lag stability upper bound as the input time lag of the whole train operation process, performing compensation through a predictor, and designing an anti-skid control strategy of the whole train operation process. According to the method, the anti-skid control target of the train can still be achieved when input time lag occurs and an actuator breaks down, and the method has important practical significance for guaranteeing the running safety of the train.

    本发明公开了一种具有输入时滞补偿和执行器容错的高速列车防滑控制方法,具体为:针对要实现防滑控制目标的列车建立具有输入时滞和执行器故障的列车黏着动力学模型;使用线性化技术处理列车模型,得到列车巡航运行阶段近似模型,并进一步进行巡航阶段控制器设计,同时得到相应时滞稳定上界;将获得的时滞稳定上界作为列车运行全过程的输入时滞,并通过预测器进行补偿,设计列车运行全过程的防滑控制策略。本发明能在输入时滞和执行器发生故障时仍能实现列车的防滑控制目标,对保障列车行驶安全具有重要的现实意义。
