In this paper, we study existence, uniqueness and global stability of periodic solution (i.e., stationary oscillation) for general nonautonomous cellular neural networks with impulses. Some criteria are obtained for stationary oscillation of the nonautonomous cellular neural networks with impulses. It is derived by using a new method which is different from those of the previous literatures. Previous results are extended and improved. An illustrative example is given to demonstrate the effectiveness and less conservativeness of the obtained results. © 2007 Elsevier Ltd. All rights reserved.
