Remarks on Estimating Upper Limit of Norm of Delayed Connection Weight Matrix in the Study of Global Robust Stability of Delayed Neural Networks

Abstract

The of estimating the the upper limit of the norm parallel to B parallel to(2) of file delayed connection weight matrix B, which is a key step in some recently reported global robust stability criteria for delayed neural networks (DNNs), is considered. An estimate of the upper limit of parallel to B parallel to(2) was previously given by Cao, Huang and Qu. More recently Singh has presented an alternative estimate. Presently it is Shown that all estimate of the tipper limit of parallel to B parallel to(2) may be found ill sonic cases. which would be ail improvement over each of the above-mentioned two estimates. Some observations concerning the determination of the least conservative upper limit of parallel to B parallel to(2) are presented. (C) 2007 Elsevier Ltd. All rights reserved.
