Abstract

With the rapid development of intelligent control, switched systems have attracted great attention. In this letter, we try to introduce the idea of the switched systems into the field of recurrent neural networks (RNNs) with discrete and distributed delays under uncertainty which is considered to be norm bounded. At first, we establish the mathematical model of the switched RNNs in which a set of RNNs are used as the subsystems and an arbitrary switching rule is assumed. Secondly, for this kind of systems, robust analysis which is based on the Lyapunov-Krasovii approach is addressed, and for all admissible parametric uncertainties, some criteria which are derived in terms of a series of strict LMIs are presented to guarantee the switched RNNs to be globally exponentially stable. Finally, a specific example is shown to illustrate the applicability of the methodology.
