摘要/Abstract

摘要： 通过分析高速动车组进站停车过程中制动力与速度之间的关系,构建动车组多质点动力学模型。由于制动停车后期产生空气制动力过程给系统带来延时影响,引入Smith预估器,采用基于RBF(Radial Basis Function)神经网络的PID控制策略与Smith预估器相结合,实现制动过程中对给定速度的跟踪控制。仿真分析表明：该混合控制器控制的列车速度与设定速度的误差小于±1 km/h,停车误差小于±0.3 m,可满足进站制动停车的要求。

Abstract: By analyzing the relationship between braking force and speed during the stop-stop process of high-speed EMU(Electric Multiple Units), the multi-point dynamics model of EMU is constructed. The Smith predictor is introduced due to the delay effect on the system caused by the braking force generated during the late braking, and the RBF(Radial Basis Function) neural network-based PID control strategy is combined with the Smith predictor to achieve tracking control of a given speed during braking. Simulation analysis shows that the error of train speed and set speed controlled by RBF neural network PID-Smith controller is less than ±1 km/h, and the parking error is less than ±0.3 m, which meets the inbound braking and parking requirement.

Key words: Electric Multiple Units(EMU), multi-particle modeling, RBF neural network, self-tuning PID control, predictive compensation control
