Abstract :
Based on quadratic stability and by means of linear matrix inequality, memory state feedback robust H-infinity controller design is considered for time-varying delay systems with nonlinear uncertainties. By solving a linear matrix inequality, the H-infinity state feedback controller is obtained. Finally, an illustrative example is presented to prove the correctness of this method.
