为实现高速列车自动停车功能,根据列车纵向动力学分析和制动系统原理,建立了高速列车非线性制动模型。针对大系统模型的强耦合、强非线性和不确定性的特点,依据列车运行速度,将非线性模型表示为T-S(Takagi-Sugeno)模型,并基于自适应模糊策略,设计了自动停车滑模控制器。控制算法通过自适应模糊系统逼近模型中不确定项和互联项的上界,消除了车间作用力及运行阻力的影响,使列车追踪理想停车曲线。依据李亚普诺夫方法证明了闭环系统的稳定性和追踪误差的收敛性。仿真结果验证了所提滑模控制器的有效性。

To realize the function of the automatic control used in high speed trains,a nonlinear brake model is built that reflects the train longitudinal dynamics and the operational principles of the brake system.A nonlinear model is transformed into a T-S fuzzy model according to the running speed of the train to handle the strong coupling,the strong nonlinearity,and the uncertainty of the large-scale system.Then we design a sliding mode stop controller based on adaptive fuzzy control schemes.The presented algorithm designs an adaptive fuzzy system,which approxi-mates the upper bound of the interconnected terms and the uncertain signals within the model,elimnating the im-pact of interacting forces between the carriages and the running resistance,and making the trains track the ideal stop curves.The stability of this closed-loop system and the convergence of tracking errors is proved using Lya-punov methods.Simulation results confirm the effectiveness of the proposed sliding mode controller.
