摘　　要：针对磁流变液阻尼器高度非线性特性导致的控制难问题,提出一种简化的逆动态模型.该模型可由速度反馈算法或力反馈算法实现,可以用来计算磁流变液的屈服应力或输入电流,使磁流变液阻尼器实时地产生一个阻尼力,并确保该阻尼力达到从各种优化算法中获得的目标控制力.在此基础上将盘式磁流变液阻尼器应用于力反馈系统中,并将简化逆动态模型用于反馈力控制.为了验证所提算法的有效性和正确性,建立一个力反馈实验系统并进行力跟踪实验,实验结果充分验证了所提方法的有效性.Aiming at the difficult control of magnetorheological fluid damper because of its highly nonlinear characteristics,a simplified inverse dynamic model is proposed.This simplification model can be used to calculate the yield stress of magnetorheological fluid or input current,makes the magnetic fluid damper produc a damping force in real time and ensure.On the basis of this the disc-shaped MR fluid damper will be used in force feedback system,and the simplified the inverse dynamic model is applied to the feedback force control.Finally,an experimental system was established and the results of which have verified the effectiveness of the proposed method.
