Abstract

This paper considers delay-dependent decentralized H_infin controller for a class of uncertain interconnected systems. The decentralized output feedback controllers are designed. Combining the Lyapunov-Krasovskii functional approach, the delay integral inequality of matrices and variable substitution, the delay-dependent sufficient conditions for the existence of robust decentralized H_infin control are presented in terms of linear matrix inequalities(LIMs). The numerical simulation shows the validity of the main results.
