Profile Tracking Control of High-speed Trains With Event-triggered Communication*

Well designed control strategy and communication mechanism can help to improve the performance and efficiency of high-speed trains during their operation. This study investigates the tracking control of high-speed trains in the context of unknown resistance coefficients and event-triggered communication. We at first transformed the train control system into a second-order uncertain strict feedback control system with the control input transmitted/refreshed discretely. Then, by the adaptive and co-design method, a new event-triggered control law, involving an adaptive law and an event-triggered mechanism, for the high-speed train is proposed. By this controller, the desired profiles of the train, composed of position and velocity, can be tracked into a small adjustable steady-state error. At last, the proposed results are verified by a numerical simulation.
