| 摘 要： | 为了实现复杂非线性车辆半主动悬架系统的减振控制,对整个系统的动力学特性和磁流变减振器的特性进行分析,得到期望的阻尼力变化趋势,并由此提出一种直接针对减振器电流的新型模糊控制策略.该策略构建了以车身加速度、减振器两端速度差以及悬架动行程作为输入的三维控制结构,并将其简化为二维结构,同时引入减振器的设计思想制定了非对称的模...

| Abstract: | To the control problem of the complicated nonlinear vehicle semi-active suspension,based on the analysis of dynamical characteristics of the system and the magneto-rheological(MR) damper,the desired altering trend of damping force is obtained.A fuzzy control strategy to determine the current of MR damper is established.A 3-D fuzzy control structure is proposed based on the vehicle acceleration,the velocity difference between the two ends of the damper and the dynamic distance of suspension.The control struc... |
