MBC策略供需函数模型研究

Study on supply-demand function models of MBC strategy

总结并改进了基于市场机制的控制MBC(Market-Based Control)策略应用于建筑结构控制时所采用的供需S-D(Supply-Demand)函数模型;基于Lyapunov第二法确立了保证受控结构系统稳定的方法,提出了确定改进S-D函数模型中各参数值的"归一化"方法并给出了相应流程;结合安装有控制装置的建筑结构的仿真计算,分析了改进模型中参数的取值对系统控制效果的影响,同时验证了采用改进供需函数模型MBC策略的合理性及有效性。

MBC strategy is an effect control approach that uses the liberal economy market to simulate a complex control system where the energy system and the controlled system are replaced by a seller and a consumer, and the merchandise＇s supply-demand （S-D） law is applied to distributing the control energy. When applying MBC strategy to civil structure control, the responses of a structure are often different from each other under different S-D function models. So how to build an appropriate S-D function repre- sening the distribution rule of structure control energy is especially important and it becomes the key of MBC strategy applied to structure control. Here, some S-D function models are presented, analyzed and improved. The stability of the controlled system is also discussed and the method to select the coefficients in these models is given for the convenience of actual engineering application.
