Abstract

Abstract: Aiming at the disadvantage of single object in railway vehicle damping system,the multi-objective optimal control law of railway vehicle damping system was devised to balance shock absorption control and energy saving control. To improve the riding comfortability and reduce the energy consumption, the multi-objective H₂/H_∞ output-feedback controller based on LMI was developed for an active suspension of 6-DOF vertical vibration model of railway vehicle. Norm H₂ of the actuator output was taken as the energy consumption indexes, and norm H_∞ of the vertical vibration displacement, the acceleration and the nutation angle was taken as the riding comfortability indexes. The results show that the controller can decrease the energy consumption of the actuator effectively and at the same time reduce the riding comfortability to an acceptable level, and make the railway vehicle obtain a good performance of riding comfortability and energy consumption of the actuator.
