建立了高层建筑风振控制的离散时间状态差分方程．利用离散随机最优控制理论，基于顺向脉动风荷载的竖向相关性，设计了具有离散卡尔曼滤波器结构的输出反馈控制器．通过具体算例说明在状态不完全可知的情况下，随机离散输出反馈控制能有效的减少结构的顺向脉动风振反应． A discrete-time state difference equation for wind-induced vibration control of tall buildings was established. Based on the discrete stochastic optimal control theory and the vertical correlation of forward fluctuating wind loads, an output feedback controller with discrete Kalman filter structure is designed. Through a concrete example, it is shown that the stochastic discrete output feedback control can effectively reduce the forward pulsating wind vibration response of the structure when the state is not completely known.
