摘　　要：依据MR智能阻尼器的力学模型,以合肥翡翠电视塔为工程背景,研究MR智能阻尼器对电视塔结构风振反应的控制效果。分别采用了2种半主动控制策略一种是基于现代最优控制理论的LQR半主动控制,另一种是基于局部反馈的模糊半主动控制策略。计算实例结果分析表明采用MR智能阻尼器对结构进行半主动控制能有效地减小电视塔结构的风振反应。Following the mechanical model of MR smart damper and taking the Hefei Jade TV tower as the engineering background, this paper studied the control effects under external wind loads. Two semi-active control strategies are used in the paper. One is LQR semi-active control algorithm, which is based upon classical LQR theory; another is fuzzy semi-active control method which uses the feedback of damper motion status. The analytical results indicated that MR smart damper using semi-active control algorithm could effectively reduce the wind responses of the TV tower.
