Abstract : "This paper addresses the global asymptotic stabilization of delayed fractional complex-valued neural networks
(FCVNNs) subject to bounded parameter uncertainty. The problem is proposed for two reasons: 1) The available
methods for uncertain dynamical systems may be too conservative; 2) The existing algebraic conditions will
lead to huge computational burden for large-scale FCVNNs. To surmount these difficulties, the delayed FCVNNs
with interval parameters are transformed into a tractable form at first. Then, a simple and practical controller–linear
state feedback controller is designed to achieve the global asymptotic stabilization. By constructing different Lyapunov
functions and utilizing the fractional-order comparison principle and interval matrix method, two sufficient
global asymptotic stabilization criteria expressed in LMI forms, are established. The obtained results in this paper
improve and extend some previous published results on FCVNNs. Finally, two numerical examples are provided to
illustrate the correctness of the theoretical results."
