Abstract

In this note, the problem of decentralized output feedback robust stabilization is studied for time-varying nonlinear large-scale systems, in which general interconnection and fully nonlinear nominal subsystems are both considered. The uncertainties dealt with in this note may be not only matched but also unmatched, and they may appear not only in interconnection but also in isolated subsystem. Then, a kind of continuous decentralized output feedback control to stabilize the system is proposed. Finally, simulation shows the effectiveness of our result.
