Application of PID type Generalized Predictive Control Algorithm in Lateral Semi active Suspension System for High speed Train
Aiming at the controller problems of the lateral suspension systems of railway vehicles,the 17 degrees lateral model of the whole vehicle were given in the paper.The generalized Predictive Control(GPC) strategy was applied to the semi active suspension systems.The traditional spectrum analysis was used to analyze the relationships among lateral,rolling and yaw vibrations that affected the lateral ride quality of the vehicle.The result shows that the lateral suspension vibration of the vehicle system is greatly reduced,and the dynamical performance and ride comfort of the vehicle system are considerably improved by using the PID GPC Algorithm.
