Abstract :
A design method of decentralized local robust state feedback controllers is presented for a class of uncertain large scale interconnected time-delay dynamical systems. In this paper, the upper bounds of delayed state perturbations, uncertainties, interconnection terms, and external disturbances are assumed to be completely unknown, and the delays are assumed to be any nonnegative constants. A class of adaptation-free decentralized local robust state feedback controllers is proposed, which can guarantee that the solutions of uncertain large scale interconnected time-delay systems are uniformly ultimately bounded.
