| 摘 要： | 以某20层钢框架结构为例,提出了一种基于LQG控制（线性二次型高斯最优控制）的跟踪控制策略.采用Davenport谱模拟脉动风速,对该结构进行风振时程响应动力分析,根据计算并结合结构在脉动风作用下的舒适度要求设计了一套独特的控制方法,最后比较了有无施加半主动控制时的结构响应,并对控制装置进行了优化设置.结果表明,这种半主动控制策略对高层钢框架结构在脉动风作用下的加速度响应具有良好的控制效果,满足了舒适度控制的抗风设计要求,有效降低了此类结构风振控制设计的成本. |

| Abstract: | Taking some 20-floor steel frame structure for example,it puts forward a tracking control strategy for wind-induced vibration with MR dampers based on LQG theory.It uses the Davenport spectrum to simulate fluctuating wind load acting on the structure,and it also presents the wind-induced vibration response analysis.According to the computation results and the design requirements,it proposes a set of unique control devices.All of the studies indicate that this innovative control strategy can significantly ab... |
