| 摘 要： | 理论研究与震害经验表明，地震时结构会产生不可忽略的平动与扭转耦合的空间振动。本文提出了基于线性最优控制理论的部分状态反馈次优控制策略和基于遗传算法的控制策略，以Marlab和Simulink为平台，采用磁流变阻尼器对双向水平地震作用下的偏心结构平．扭耦联反应进行半主动控制。对-6层双向偏心框架结构进行控制效果仿真分析的结果证明，本文提出的2种控制策略是有效的。

| Abstract: | Theoretical research and earthquake damage investigation turn out that there is non-negligible spatial vibration resulting from coupled translation and torsion vibration in structures when earthquake occurs. Partial state feedback sub-optimum control law based on linear optimizing control theory and control law based on genetic algorithm are presented in this paper. With the Matlab and Simulink, the semi-active control is implemented on eccentric structure under two-way horizontal earthquake using magneto-rheological damper, in order to control the coupled translation and torsion response. Taking a bilateral eccentric frame structure for example, the control effect is analyzed. And it turns out that the two proposed control laws are valid. |
