文摘

In this paper, we concerned the stability for a class of non-linear uncertain stochastic systems with time-delay. With the employment of Jensen integral inequality, free-weighting matrix and Schur complement, a novel Lyapunov-Krasovskii functional is constructed and the delay-dependent sufficient criterion of theorem is established. Some examples such as single-machine infinite-bus system are given to verify the applicability and feasibility of the proposed method.
