含饱和作动器的主动TMD振动控制研究

RESEARCH ON ACTIVE TMD VIBRATION CONTROL WITH SATURATION ACTUATOR

以含主动调谐质量阻尼器(TMD)的建筑结构为研究对象,研究作用于TMD上的作动器输出力小于设计控制力时的控制方法.为了确定系统控制率,在满足线性矩阵不等式约束的前提下,通过优化控制目标函数来达到.同时,为了保证控制效果,采用了峰-能量控制器.最后,以一座六层建筑物为例来说明本文方法的可行性.

The building structures with tuned mass damper （TMD） were used as research object, and a controll strategy was proposed when the output force of the TMD actuator was less than the designed controll force. The optimization method was used to search for the system control-law under the condition that the premium of the linear matrix inequalities（LMIs） was satisfied, and the peak-energy controller was adopted for assuring the control effect. Finally, an example of 6-storey building was used to illustrate the feasibility of the presented method.
