Abstract: The problem of the state estimation for delayed neural networks with stochastic sampleddata control was studied. First, a unified probability framework involving the stochastic sampling interval and the sampling input delay was proposed. Second, based on this unified probability framework, a new LyapunovKrasovskii functional (LKF) with some new terms was constructed. Third, with this LKF and some inequality technologies, a less conservative criterion was established, which can ensure the stochastic stability of the error system. The desired state estimator was designed. Finally, numerical simulation results show the effectiveness and advantages of the proposed method. -
