大型复杂结构模糊物理边界划分与多市场竞争控制

Physical border division of large complex structures based on fuzzy clustering method and multi-market based control

基于模糊均值聚类(Fuzzy clustering Method,FCM)理论提出大型复杂结构边界划分方法,通过建立大型复杂结构信息数据矩阵,进而确定数据中心,实现了基于FCM的大型复杂结构边界划分方法。与多市场竞争控制(Multi-Market Based Control,MMBC)理论相结合,形成大型复杂结构分散控制体系。将FCM方法和MMBC理论相结合,对某剪切型半主动控制结构在地震作用下的振动反应进行分析,验证提出的FCM理论应用于子结构边界划分中的有效性,虚拟价格时程曲线反应各子市场价格波动的合理性。分析结果表明,MMBC策略对离散后的子结构中阻尼器出力具有较好的控制作用,同时可以有效减小结构在地震荷载作用下的振动反应。

A method for dividing the boundary of complex structures,based on Fuzzy Clustering Method（FCM） theory,is presented.The boundary of a complex structure is described using data matrix,and the center of the data matrix is defined through FCM,then the boundary of the complex structure is determined.A complete decentralized control system is formed,which combines the boundary division method based on FCM theory and Multi-Market Based Control（MMBC） strategy.A numerical example of building with MRD under earthquake is presented to illustrate the accuracy and efficiency of the proposed method.
