Abstract

This paper proposes a train control method applied in railway virtual coupling technology. We simplify the virtual coupling formation into two trains, with the front train termed the leading train and the rear train termed the following train. When the state part of the leading train is observable, we use the Partial Observable Markov Decision Process (POMDP) model to predict the operational trajectory of the leading train. The prediction results are then relayed to the Model Predictive Control (MPC)-based controller of the following train, where MPC is utilized to control the following train and provide predictions for its operation. Experimental results indicate that such a method enables the following train to effectively track the leading train.
