摘要: 针对车辆减振系统中的目标单一的问题,应用H2/H控制算法实现轨道车辆减振系统集减振、节能于一体的多目标优化控制。采用6自由度轨道车辆垂向振动模型为控制对象,以得到较好乘坐舒适性和较少能耗为控制目的,选取作动器控制输出力的H2范数作为能耗指标,以车体浮沉振动位移和加速度、点头振动转角的H范数作为车辆乘坐舒适性指标,设计基于LMI的H2/H输出反馈控制器。研究结果表明,该控制器能在保证不过多降低车辆乘坐舒适性的同时,能有效降低作动器能耗,较好地解决了车辆舒适性和作动器能耗之间的矛盾

关键词: 轨道车辆, H2/H控制;, 乘坐舒适性, 能耗

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.

Key words: rail vehicle, H2/Hcontrol;, riding comfort, energy consumption
