Profile tracking control of high-speed trains with event-triggered communication

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