| 摘 要： | 本文在传统的车辆悬挂设计方法的基础上提出了一种主动悬挂的最优自适应控制方法:首先利用优化方法找出悬挂参数与激励(路面谱与车速)之间的最优对应关系,而激励的大小又可通过车身振动加速度来反映,从而推导出根据车身振动加速度反馈来调节悬挂参数的一种新的最优自适应控制方法.仿真计算结果表明该控制方法是有效的,也是易实现的.

| Abstract: | The paper presents an optimal adaptive control law for vehicle's active suspensions on the base of traditional design method: the optimal corresponding relation between the suspension parameters and excitations is obtained by optimal designing method, however the excitation can be expressed by the vehicle body's vibration acceleration, thus a new kind of optimal control method to adjust the suspension parameters according to the body acceleration is obtained. The simulating calculation results indicate that the control method is effective and also feasible. |
