Abstract: Delay-dependent decentralized robust H∞ controller for a class of interconnected large-scale systems was researched. The time-delays were assumed as time-varying. First, the decentralized state feedback H∞controllers were designed. A method called Integral Inequality Method (IIM) was introduced. Combining the Lyapunov-Krasovskii functional approach, the integral inequality of matrices and the modified Cone Complementary Linearization (CCL) algorithm, the delay-dependent sufficient conditions for the existence of robust decentralized H∞ control were presented in terms of nonlinear matrix inequalities and linear matrix inequalities. Second, the results were extended to the case of decentralized output feedback. At last, the numerical simulation shows the validity of the main results.
