Abstract

In this paper, the global asymptotic stability of uncertain fuzzy Hopfield neural networks(UFHNNs) with time-varying delays is investigated. Firstly, a new fuzzy Lyapunov function comprising a special line-integral function of fuzzy vector is proposed. Then by using the Wirtinger-based integral inequality to determine the upper bound of the derivative term of the Lyapunov function more accurately, a new stability criterion with less conservatism is derived in the form of linear matrix inequality(LMI). At last, an examples is given to show the effectiveness and superiority of our result.
