摘要
在建筑结构的半主动控制中 ,多以结构的位移和速度反应作为状态反馈 ,但是实际工程中会产生测量不便以及误差累积等问题 .为此 ,利用加速度测量简单、可靠的特点 ,采用加速度作为反馈变量来实现建筑结构的磁流变阻尼器半主动振动控制 .计算实例分析结果表明 ,此控制策略能够有效地减少结构的地震反应 。
The usual semi active control strategies are with the feedbacks of displacement and velocity responses of structure. But in actual condition it is difficult to measure the displacement responses precisely. This paper focused on the research of semi active magnetorheological damping control with acceleration feedbacks since the acceleration responses can be easily measured by installing acceleration sensors in the controlled structure. The results of the example illustrate that this control algorithm can efficiently reduce the structural responses induced by earthquake and can even achieve almost equivalent performance to that of active control algorithm.
