Robust stability of discrete-time stochastic neural networks with time-varying delays

In this paper, the robust exponential stability problem of discrete-time uncertain stochastic neural networks with timevarying delays is investigated. By introducing a new augmented Lyapunov function, some delay-dependent stable results are obtained in terms of linear matrix inequality (LMI) technique. Compared with some existing results in the literature, the conservatism of the new criteria is reduced notably. Three numerical examples are provided to demonstrate the less conservatism and effectiveness of the proposed method. Keywords—Robust exponential stability, delay-dependent stability, discrete-time neural networks, stochastic, time-varying delays.
