中文摘要：
地震作用下,偏心结构将不可避免的产生平动-扭转耦联的空间振动.采用水平双向布置MR阻尼器的方法对偏心结构的多维振动进行控制,针对此控制系统,在现有MBC控制策略的基础上加以改进,建立多商品市场模型和计算理论,提出了改进MBC控制策略.＂多商品＂代表结构振动的多维性,通过市场中买卖双方的供求竞争达到MR阻尼器出力的合理分配.采用Matlab/Simulink实现控制系统的仿真模拟.对一双向水平地震动作用下的6层偏心结构进行动力计算,比较了改进MBC算法和经典LQR算法的控制效果.
英文摘要：
There is inevitable spatial vibrations resulting from coupled translation and torsion response of structures when earthquake occurs. In this paper the MR dampers are used for structural control system in two horizontal directions of every story to limit the spatial responses. Based on Market-based Control, an advanced approach is derived that it models such a structural control system as a marketplace with multi-modifications. Different modification indicates the different control demand of the distributed structure. The interaction of free-market buyers and sellers results in an optimal allocation of limited control resources. A 6-story structure is selected to compare the performance of the Advanced Market-based Control （AMBC） and LQR approaches.
