In order to suppress the lateral vibration and improve the ride comfort of the train, a method of solving the lateral vibration problem with H∞ robust controller was proposed. Through reasonable simplification, a lateral dynamic model of a certain subway train is established, and a reasonable weighting function is selected for the sensitive frequency segment of human body and the resonance frequency point of the car body. H∞ robust controllers based on mixed sensitivity PS/T were designed for yaw and lateral. The actuator selection in full active control is carried out and the optimal actuator transfer function for a metro train is selected through simulation. Simulink and SIMPACK co-simulation model were established to simulate the actual working conditions. The results showed that H∞ robust controllers could effectively suppress the lateral vibration of the vehicle body, improve the running quality and ride comfort of the train, and the controller took both stability and robustness into account.
