This article deals with the problem of robust H∞ control for uncertain stochastic singular systems with time-varying delays.By constructing Lyapunov functional and employing improved free matrix inequality and Itô's formula,a state feedback controller is designed to ensure that the resulting closed-loop system is robustly mean-square admissible for all uncertainties and has an H∞ performance index γ.Finally,an illustrative example is given to demonstrate the effectiveness of the present method.
