Decentralized output feedback robust control for nonlinear large-scale systems

In this note, the problem of decentralized output feedback robust stabiliza tion is studied for time-varying nonlinear large-scale systems, in which ge neral interconnection and fully nonlinear nominal subsystems are both consi dered. The uncertainties dealt with in this note may be not only matched bu t also unmatched, and they may appear not only in interconnection but also in isolated subsystem. Then, a kind of continuous decentralized output feed back control to stabilize the system is proposed. Finally, simulation shows the effectiveness of our result. (C) 1998 Elsevier Science Ltd.
