时滞与补偿是基于磁流变流体阻尼器（Ｍａｇｎｅｔｏｒｈｅｏｌｏｇｉｃａｌ Ｆｌｕｉｄ Ｄａｍｐｅｒ，简称ＭＲＦＤ）的半主动控制系统优化设计中的一个重要问题。本文对此进行了研究，并通过计算实例分析了时间滞后与补偿两种情况对控制系统性能的影响，结果表明，当时滞达到１．０ｓ时，ＭＲＦＤ半主动控制系统仍具有一定的控制效果，说明该半主动控制系统是可靠的，其性能要优于完全主动控制系统，并且对时滞补偿以后系统的控制效果得到明显的改善，说明本文所述的时滞补偿方法是有效的。
Time delay and compensation are an important issue in the optimization design of semi-active control system based on Magnetorheological Fluid Damper (MRFD). In this paper, we study the effect of time lag and compensation on the performance of the control system through calculation examples. The results show that the MRFD semi-active control system still has some control effects when the time lag reaches 1.0s, It shows that the semi-active control system is reliable and its performance is better than that of the fully active control system. And the control effect of the system after the delay compensation is obviously improved, which shows that the time-delay compensation method described in this paper is effective.
