Precise train stopping method based on predictive control

Precise train stopping is a key technology of automatic train operation. On the basis of analyzing the train stopping phase, the delay characteristics of brake model and constraint conditions of train characteristics were considered, using generalized predictive control theory, a multi-objective predictive controller with constraints was designed taking account of train speed and distance as control targets and combining the control constraint conditions. The simulation results show that the proposed controller can accurately track the train stopping curve to achieve high precision stopping requirements and higher comfort.
