Abstract

Abstract : This study investigates the coordinated braking strategy integrated with sliding mode control for multiple high‐speed trains, to solve the problem of non‐linear couplers between trains and uncertainty during the braking process. First, a multi‐agent model with power between trains and uncertainty is established. Secondly, a sliding mode consistency tracking controller is designed. The consensus algorithm assures the consistency convergence of speed of each carriage. Sliding mode variable structure term is used to deal with the compound interference item consisting of non‐linearity and uncertainty. Finally, it is demonstrated by a simulation experiment that, the algorithm can well deal with compound disturbance term so that high accuracy is obtained during the parking process.
