High Speed Train Tracking Control Based on Global Terminal Sliding Mode Method

With the rapid development of society, in today's fast-paced life, the continuous progress of rail trains, the increasing number of trains, the increase in operating speed, and the operating environment has become more and more complicated. The operation control method can no longer satisfy the current transportation system. Therefore, it is of great significance to study the new train automatic driving algorithm. This paper studies the sliding speed control algorithm based on global terminal sliding mode. The details are as follows: Firstly, consider the uncertain factors encountered by the train as a whole, design a train speed tracking algorithm, combine the basic resistance of the train and the additional resistance received into one resistance, eliminate the impact of other uncertain factors, and establish a single particle point train model. Then, research the fast terminal sliding mode control, design the sliding mode controller, and use the characteristics of sliding mode control to produce small fluctuations and fast response to parameter changes, and design a sliding mode control algorithm for high speed train tracking. Finally, write the MATLAB program of the train model and sliding mode controller, and use Simulink to combine the two programs together, and verify whether the actual speed curve can track the target speed curve through MATLAB simulation images. The image simulation results show that the actual speed curve output by the sliding mode controller can accurately track different target speed curves in a limited time.
