Zixin Liu, Shu Qing Lv, Shouming Zhong, Mao Ye · Discrete Dynamics in Nature and Society · 2009
The robust stability of uncertain discrete‐time recurrent neural networks with time‐varying delay is investigated. By decomposing some connection weight matrices, new Lyapunov‐Krasovskii functionals are constructed, and serial new improved stability criteria are derived. These criteria are formulated in the forms of linear matrix inequalities (LMIs). Compared with some previous results, the new results are less conservative. Three numerical examples are provided to demonstrate the less conservatism and effectiveness of the proposed method.
