The high-speed train operation control process is a strong nonlinear problem which is restricted by a plurality of factors such as vehicle characteristics, line conditions and the like, and the train operation performance is directly influenced by the performance of a train control algorithm. In recent years, with the development of technologies such as communication and control, cooperative train control has become a research focus. In the process of considering the cooperative operation of multiple trains, on the premise of ensuring high confidence rate in the information interaction process between the vehicle-mounted control subsystem and the ground control subsystem, the phenomenon of information transmission time lag is difficult to avoid, the transmission time lag in the information interaction process has numerous factors and complex mechanism, and time lag information is difficult to accurately model. Therefore, how to compensate the complex information interaction time lag phenomenon, and realizing accurate and stable control of multiple trains still deserves further thinking and research.
