The guaranteed cost control problem of the decentralized robust control for a class of large-scale interconnected systems with norm-bounded time-varying parameter uncertainties is considered. Based on the LMI design approach, a class of decentralized local state feedback controllers is proposed, and some sufficient conditions for the existence of guaranteed cost controllers are derived by making use of the LMI.
