摘要

A novel control strategy is proposed to improve the lateral smoothness of high-speed train (HST) carbody. The 3-degree-of-freedom (DOF) lateral model of HST is designed and verified. The effects of yaw damper damping and secondary lateral damping on the lateral vibration of the HST are investigated. And the particle swarm optimization (PSO) algorithm is designed to optimize damping. To reduce the lateral vibration of the carbody, a super-twisting sliding model control (STSMC) strategy is proposed. The Lyapunov method is utilized to prove the convergence of STSMC strategy. After analyzing the control effect and energy consumption of STSMC strategy, an active-passive super-twisting sliding mode control (APSTSMC) strategy is proposed. The state space method is used to demonstrate the convergence of APSTSMC strategy. The effects of HST running speed, wheel-rail equivalent conicity, and aerodynamic loads on the control effects of STSMC and APSTSMC strategies are investigated. The results indicate that both STSMC and APSTSMC strategies can significantly reduce the lateral acceleration of carbody in a wide frequency band. However, the APSTSMC strategy consumes less energy and has better prospect for engineering application.
