Design of Robust Decentralized Dynamic Controller for Uncertain Large-Scale interconnected Systems with Time-Delays

摘要

In this paper, we present a dynamic output feedback controller design technique for robust decentralized sta- bilization of uncertain large-scale systems with time-delay in the subsystem interconnections. Based on Lyapunov second method, a sufficient condition for the stability, is derived in terms of three linear matrix inequalities (LMI). The solutions of the LMIs can be easily obtained using efficient convex optimization techniques. A numerical example is given to illustrate the proposed method.
