Mean-square exponential stability of stochastic Hopfield neural networks with time-varying discrete and distributed delays.
(English)
[J] Phys. Lett., A 373, No. 25, 2154-2161 (2009). ISSN 0375-9601

Summary: In this Letter, the mean-square exponential stability problem for stochastic Hopfield neural networks with both discrete and distributed time-varying delays is investigated. By choosing a modified Lyapunov-Krasovskii functional, a delay-dependent criterion is established such that the stochastic neural network is mean-square exponentially stable. The derivative of discrete time-varying delay $h(t)$ satisfies $\dot{h}\leq \eta$ and the decay rate $\beta$ can be any finite positive value without any other constraints. The assumptions given in this Letter are more general than the conventional assumptions (i.e., $\dot{h}((t)\leq \eta < 1$ and $\beta$ satisfies a transcendental equation or an inequality). Finally, numerical examples are provided to illustrate the effectiveness of the proposed sufficient conditions.
