摘要 将磁流变阻尼器用于建筑结构振动控制是当前研究的前沿课题之一.文章介绍了存在时滞的磁流变阻尼控制系统的动态系统方程和控制算法,对在地震激励下的磁流变阻尼控制进行数值仿真,并研究时间滞后对磁流变阻尼控制系统在控制效果上的影响,且与主动控制系统进行了比较. It is a frontier topic of current study to apply magnetorheological fluid damper (MRFD) to the vibration control of civil structure. This paper presents state-space equation and control algorithm of MRFD system when time delay occurs, and carries numerical simulation to MRFD under earthquake force. The effect of time delay on the control efficiency of MRFD is thereafter studied, and is compared with that of the actively controlled system.
