Abstract. This paper considers the global
exponential stability and stabilization for a class of neural networks with
mixed interval time-varying delays. The time delay is assumed to be a
continuous function belonging to a given interval, but not necessary to be
differentiable. By constructing a set of new Lyapunov-Krasovskii
functionals combined with Newton-Leibniz formula,
new delay-dependent criteria for exponential stability and stabilization of
the system are established in terms of linear matrix inequalities
(LMIs), which allows to compute simultaneously the two bounds that
characterize the exponential stability of the solution. Numerical examples
are included to illustrate the effectiveness of the results.
