| Abstract: | The decentralized robust stabilization problem with a class of large-scale delay-dependent systems，is bounded persistent disturbance．By constructing Lyapunov functions，the linear matrix inequality(LMI)was employed．A few sufficient conditions for such large-scale systems were derived．A convex optimization of LMI constraints was formulated to design a decentralized state feedback control with smaller gain parameters，which enables the closed．1oop system to be asymptotically stable．Th e given example verifies the effectiveness of the method． |
