                | In this paper, we study with robust stabilization problem of uncertain stochastic time-varying delay systems with nonlinear perturbation. Constructing a suitable Lyapunov-Krasovskii functional and employ the free weighting matrix method, in terms of the linear matrix inequality (LMI) technique, we design a memoryless state feedback controller, and obtain delay dependent robust stabilization criterion for the uncertain stochastic time-varying delay systems. A numerical example and its simulation curve are given to show that the proposed theoretical result is effective. |
