摘　　要：针对输入荷载特性未知的高层建筑结构在集中控制下的可靠性低、计算量大等局限性,本文提出从分散H2/H∞鲁棒控制理论出发,对其进行线性矩阵不等式(LMI)求解,从而实现对多个子系统的多自由度建筑进行分散控制的方法。通过对一个高层剪切型建筑结构进行仿真运算,探讨了土木工程中运用分散控制方法的有效性,以及该方法对建筑结构进行分散主动和半主动控制的一些特性。In view of the limitation of low reliability and calculative overload in the large-scale building structure centralized control with uncertain disturbance, this paper researches into a decentralized H2/H∞ robust control method for large-scale building containing multi-substructures by solving linear matrix inequalities. The validity of this method is confirmed through a simulating example of multistorey shear frame, and some characteristics of actire, semi-active control of this method are studied.
