In this paper, we study the robust stability for a class of grey stochastic systems with impulsive effect and time-varying delay. Based on the stochastic stability condition of impulsive stochastic functional differential systems presented by this paper, we first deduce a criterion of stochastic robust stability for such a system by using the Lyapunov-Krasovskii functional method and the decomposition technique of continuous matrix-covered sets of grey matrix. Then by using the obtained criterion of stochastic robust stability and Dini derivative, we give an exponential robust stability criterion for such a system. The  ffectiveness and practicality of the presented criteria is confirmed by a numerical example.
