一般信息结构下的Robust控制器

本文在文献1,2,3]的基础上,直接给出了一般信息结构(GIS)下,系统的一类Robust 控制器的结构、存在条件和设计方法,避免了用间接方法4]的要增加输出向量维数和使观测 矩阵降秩的不足之处.推广了文献1]和2]的集中和块对角分散信息结构下的有关结论. 若所讨论的GIS是经济信息结构5,6,7,8],则该GIS下的Robust控制器即为经济Robust控 制器.最后举例说明本文方法的应用.

The Robust Controller Under General Information Structure

On the basis of papers 1,2,3], this paper gives the structure, condition for the existence, and the design procedure of a class of robust controller of the system which are subject to a given general information structure (GIS). The method given in the paper overcomes the drawbacks of increasing the dimension of output vector and making the output matrix not have full rank, which may occur when the GIS are transformed into the block diagonal IS. The paper generalizes the reaults of paper 1] and 2] which deal with the centralized and decentralized IS respectively. If the GIS K is an economic IS, then the robust controller constructed under K is an economic robust controller, Finally, two examples are given for illustruation.
