Decentralized variable gain robust practical tracking for a class of uncertain large-scale interconnected systems

Abstract

In this paper, we consider the design problem of a decentralized variable gain robust controller that provides practical tracking for a class of large-scale interconnected systems with mismatched uncertainties. Furthermore, we show that sufficient conditions for the existence of the proposed decentralized variable gain robust controller are reduced to the feasibility of linear matrix inequalities. Finally, we present a simple numerical example to demonstrate the effectiveness of the proposed decentralized robust control system.
