This paper is concerned with the problem of passification for a class of uncertain stochastic time-delay systems based on sliding mode control.By constructing an appropriate Lyapunov-Krasovskii functional and introducing some free-weighting matrices,some delay-dependent sufficient conditions are established in terms of linear matrix inequalities to guarantee the robust stochastic stability of the closed-loop system for all admissible uncertainties.Based on the conditions,the corresponding reaching motion controller is designed.Finally,a numerical example is presented to demonstrate the effectiveness of this control scheme.
