| Abstract: | By defining an appropriate, Lyapunov-Krasovskii functional and by employing a new inte- gral equality and some inequalities to deal with the bounding for the cross terms,a sufficient condition is derived in term of linear matrix inequalities （LMIs） such that the uncertain stochastic system is robustly asymptotically stable in the mean square sense. Numerical example is given to illustrate the effectiveness of the proposed method and an improvement over some existing results in the literature. |
