Abstract
In this paper, the stability analysis of neural networks with two additive time-varying delay components is considered. By constructing an augmented Lyapunov–Krasovskii functional, an improved delay-dependent stability criteria are derived by utilizing the delay-partitioning approach, which can effectively deal with the integral terms. As a result, no bounding technique is involved. Two illustrative examples are listed to show the effectiveness of the proposed method.
