High speed train tracking observation based on sliding mode controller

A sliding mode controller-based control technique is devised to tackle the doubt of the high-speed train dynamics model and the challenge in attaining tracking control of the target trajectory due to outside disturbances. Firstly, a high-speed train dynamics model is established through force analysis of the train. The Lyapunov stability analysis, which guarantees the asymptotic stability of the closed-loop system, was employed to devise a sliding mode controller to tackle the uncertainty of the high-speed train model's nonlinear system. To validate the controller's efficacy, simulation examples were provided.
