Observer-based controller design for uncertain large-scale systems with time-delays in subsystem interconnections

Abstract

In this paper, the decentralized stabilization problem of uncertain large-scale systems with time-delays in subsystem interconnections is investigated. An observer-based controllers is developed using the Lyapunov method. For robust stability of the system, a sufficient condition is derived in terms of linear matrix inequalities (LMIs) which are solved by convex optimization algorithm. A numerical example is given to illustrate the proposed technique.
