摘要
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 important problem in semi-active control system using magnetorheological fiuid damper. Through an example, the influence of time-delay and compensation on the performance of control system is analyzed. When the delayed time amounts to 1.0 second, MRFD send-active control system has still some control effectivenss. It is proved that this send-active control system is reliable and its performance is better than the active control system. When the delayed time is compensated, the control effectiveness of the system will be im- proved and it is proved that this method of compensation of time-delay is effective.
