Abstract

To improve the line operation adaptability of high-speed trains, a Model Predictive Control (MPC) method based on anti-yaw damper is proposed to realize the stability control of vehicle hunting motion based on the real-time adjustment of the damping value of the shock absorbers. A simplified dynamic model with seven degrees of freedom in the lateral direction of the whole vehicle is established, including the traverse, yaw and roll degrees of freedom of the vehicle body, the traverse and yaw degrees of freedom of the bogie, and the linear wheel-rail contact relationship is considered. Based on Model Predictive Control (MPC) theory, the active yaw damper is designed, the objective function and constraint conditions are established, and the optimal damping coefficient is solved. The effect of the stability control of vehicle hunting motion is analyzed. The results show that compared with the passive suspension, the MPC active yaw damper can effectively suppress the primary hunting motion of the vehicle, but the restraint effect on the second hunting motion of the vehicle is not obvious.
