- In this paper, we study the effect of parameter mismatches on the fuzzy neural networks with impulses. Since it. is impossible to make two non-identical neural networks complete synchronized, we study the synchronization of two neural networks in terms of quasi-synchronization. Using Lyapunov method and linear matrix inequality method, we obtain a sufficient condition for a global synchronization error bound of the two neural networks. Springer-Verlag Berlin Heidelberg 2007.
