建筑结构振动智能化最优控制设计

Optimal Design of Intelligent Control of Building Structure Vibration

高层建筑结构在风、浪、地震等动载荷影响下易产生动态响应,此过程中易出现较大的位移响应,从而对高层建筑结构安全造成巨大威胁。为了对建筑结构动态响应进行有效控制,基于稳定逆理论提出了一种最优迭代学习控制方法,对算法收敛性进行分析。仿真结果表明,该方法能有对Benchmark模型的地震位移响应进行有效控制,使得控制效果得到一定的改善。

High- rise buliding is easy to produce the dynamic response,big displacement response under the influence of wind,wave,earthquake and other dynamic loads,which is a great threat against the safety of the high- rise building structure. In order to control its dynamic response a control method based on the stable inverse of the optimal iterative learning algorithm is proposed,and the convergence of the algorithm is analyzed. The simulation results show that the new control strategy can be used to effectively control earthquake displacement response.
