结构MBC策略的财富分配方法研究

Analysis of wealth distribution in MBC strategy

总结了已有的基于市场机制控制(Market Based Control,MBC)策略中的财富分配方式。财富分配方式不同直接会影响MBC算法的控制效果,根据结构反应特点,提出了两种财富分配方式:以结构剪力为优化目标的线性财富分配和以结构位移为优化目标的模态财富分配。对一安装有控制装置的20层结构进行了数值分析,比较了这两种财富分配下的MBC控制算法,并与经典LQR算法的控制效果进行了对比。研究表明,提出的两种财富分配方式能有效的控制结构响应,并验证了其合理性。

Present methods of wealth distributions based on the Market based Control （MBC） strategy are summarized. Selec- tion of wealth distribution approach directly influences the control effect of MBC algorithm. Therefore two approaches of wealth distribution, linear and modal wealth distribution forms are proposed according to the characteristics of structural responses. The control effects of the two wealth distribution methods in MBC algorithms are compared with classical LQR control method by simulating for a 20-storey structure equipped with control device. The results demonstrate the effectiveness of the proposed two wealth distributions in structural response control, as well as their rationality.
