Analysis on delay-dependent stability for neural networks with time-varying delays

This paper considers the problem of delay-dependent stability criteria for neural networks with timevarying delays. First, by constructing a newly augmented Lyapunov–Krasovskii functional, a less conservative stability criterion is established in terms of linear matrix inequalities (LMIs). Second, by proposing a novel activation function condition which has not been considered, a further improved result is proposed. Finally, two numerical examples utilized in other literature are given to show the improvements over the existing ones and the effectiveness of the proposed idea. & 2012 Elsevier B.V.
