Boundedness and global exponential stability for generalized Cohen--Grossberg neural networks with variable delay. (English) Zbl 1090.92004
Summary: A generalized Halanay inequality is established, and the boundedness of generalized Cohen-Grossberg neural networks [{\it M. A. Cohen} and {\it S. Grossberg}, IEEE Trans. Syst. Man Cybern. 13, 815--826 (1983; Zbl 0553.92009)] is investigated. By applying the generalized Halanay inequality and Lyapunov functional methods, new sufficient conditions are obtained ensuring the global exponential stability of solutions of generalized Cohen-Grossberg neural networks with variable delay. Three examples are also given for illustration.
