چکیده
Abstract— In this paper, we propose a decentralized variable gain robust controller which achieves not only robust stability but also satisfactory transient performance for a class of uncertain large-scale interconnected systems with state delays. The proposed decentralized robust controller consists of a fixed feedback gain controller and a variable one tuned by parameter adjustment laws. In this paper, it is shown that sufficient conditions for the existence of the proposed decentralized variable gain robust control system are given in terms of LMIs. Finally, a simple illustrative example is shown.
