基于H_∞鲁棒控制原理和使用ATMD的高楼主动振动控制策略研究

H∞ Robust Control Based on Active Vibration Control for Tall Buildings Using ATMD

对使用主动调频质量块ＡＴＭＤ的具有ｎ阶自由度的柔性大楼结构建立了全阶模型，并将得到的结构降阶模型用于设计ＡＴＭＤ控制器。通过分析，大楼结构的位置和速度可选为控制器的输出反馈变量。将等效两端口模型应用于带ＡＴＭＤ的大楼结构，使用Ｈ∞频域定型综合理论，设计出ＡＴＭＤ的鲁棒控制器。仿真证明该控制算法是非常有效的。

The modeling work have been done for the flexible builiding structure with n-th freedom order and the reduced model can be gotten to design the controller for ATMD. According to the analysis, the displacement and velocity of the building structure can be chosen as the output feedback variables for the controller. By using the equivalent two-port model of the buliding structure with ATMD, a robust controller can be designed for ATMD based on the H∞ frequency shaping synthesis theory. With the results of simulation, it is found that the control algorithm is very effective.
