摘要
将模型预测控制算法应用到多层建筑结构地震反应控制中,在分析受地震波激励的多层建筑结构模型的运动方程和加速度方程及其状态空间形式基础上,确定预测模型和控制目标函数,建立了多层建筑结构预测控制系统。利用Matlab/Simulink工具对12层建筑结构模型进行地震反应的预测控制仿真,结果表明,预测控制能显著减少多层建筑的地震反应,且减振效果非常明显。
Model predictive control algorithm was implemented for the structural vibration control of the tall building under earthquake excitation based on analyzing structural motion equation,acceleration equation and the state space form of structural model of earthquake-excited tall building,predictive model and control target functions were defined and the MPC(system) of tall building was set up.MPC of 12-story tall building under earthquake excitation was simulated using Matlab/Simulink toolboxes.The result of simulation shows that MPC can greatly reduce earthquake response of the tall building and mitigation effect is very available.
