Synthesis of Decentralized Variable Gain Robust Controllers with Guaranteed 葦2 Gain Performance for a Class of Uncertain Large-Scale Interconnected Systems

We consider a design problem of a decentralized variable gain robust controller with guaranteed 葦2 gain performance for a class of uncertain large-scale interconnected systems. for the uncertain large-scale interconnected system,the uncertainties and the interactions satisfy the matching condition. in this paper,we show that sufficient conditions for the existence of the proposed decentralized variable gain robust controller with guaranteed 葦2 gain performance are given in terms of linear matrix inequalities (lmis). finally,simple illustrative examples are shown. © 2015 shunya nagai and hidetoshi oya.
