ABSTRACT
During the operation of high-speed trains, in order to achieve the goal of punctuality and efficiency, the speed of the train is usually monitored in real time, and real-time speed adjustments are made, so as to meet the requirements of ideal speed tracking. In this paper, a basic model of train force is established for the change of resistance parameters of trains on different lines, and the control law of reference adaptive control theory is used to achieve the effect of coping with the effect of parameter changes, that is, to adjust speed to reduce or eliminate uncertain resistance factors. The train adaptive control strategy in the article is based on the Lyapunov design method and has a faster convergence. Through the analysis of the simulation results of the train operation process, it is proved that the uncertainty problem caused by the complicated operation line conditions of the high-speed train can be effectively dealt with, and the tracking purpose within a small error can be achieved, thus ensuring the safety and reliability of the high-speed train operation. It also shows the feasibility of the reference model adaptive control in the application of train speed tracking.
