Abstract
This article investigates the H∞ state estimation for neural networks with both discrete and distributed time-delays. A new Lyapunov–Krasovskii functionals (LKF) is established by including two novel delay-product-type terms, multiple integral terms and more general activation function. Then, by utilizing the generalized free-weighting matrix inequality and dividing the boundary of activation function into two parts, new sufficient conditions are derived such that the estimation error system is asymptotically stable with desired H∞ performance level. Finally, the advantages of presented method are demonstrated through three numerical examples.
