The robust and non-fragile guaranteed cost control of uncertain linear systems with distributed delay is
investigated. Both the distributed-delay system and the state feedback controller are assumed to have time-varying
uncertainties. A sufficient condition in terms of linear matrix inequality is established for the existing of the robust non-
fragile guaranteed cost controller by constructing new Lyapunov-Krasovskii functional with triple-integral term and using
inequality technique. The proposed approach can keep the quadratic performance function below a supper bound and delay-
dependent. Simulation examples show the effectiveness and feasibility of the method.
