Lagrange stability analysis for complex-valued neural networks with leakage delay and mixed time-varying delays

This paper discusses the stability in Lagrange sense for complex-valued neural networks with time varying discrete delays and distributed delays as well as leakage delay. By constructing an appropriate Lyapunov-Krasovskii functional, and employing free-weighting-matrix approach and inequality techniques in matrix form, a sufficient criterion to guarantee global exponential stability in Lagrange sense is obtained for the investigated neural networks. The given criterion is delay-dependent and is shown as linear matrix inequalities in complex domain, which can be calculated numerically applying valid YALMIP toolbox in MATLAB. A numerical example is provided to manifest the validity of the proposed result. (C) 2017 Elsevier B.V. All rights reserved.
