Precise Train Stopping Algorithm Based on Deceleration Control

Precise train stopping is a key technology in train brake control systems. The traditional control research is based on the speed curve following, and this paper proposes a strategy based on the deceleration curve following. After establishing the theory simulation model, this paper designs the ideal curve of target deceleration. In order to follow curve well, the train kinematics model is linearized and an adaptive control algorithm is designed. The simulation analysis shows that the algorithm can guarantee the stopping accuracy and ensure the gentle change of the deceleration. It also shows that the control idea based on the deceleration curve is feasible and has unique advantages, which provides a direction for the subsequent algorithm research.
