Output feedback H∞ robust control for uncertain multiple time-varying delays systems with nonlinear perturbations

Output feedback robust H-infinity stability for uncertain systems with multiple time-varying delays and nonlinear perturbations is studied. The delay is time varying. The uncertainties are norm bounded, and the nonlinear perturbations meet linear constraints. Based on Lyapunov-Krasovskii functional, two new delay-dependent results are presented in terms of matrix inequalities technique and nonlinear dealing method. In the end, a example is given to illustrate that the presented method is effective.
