| 摘 要： | 通过构造适当的Lyapunov函数,利用Halanay不等式和Young不等式,讨论一类具有变时滞的Hopfield型神经网络的全局指数稳定性.在对网络施加两个不同的神经元激励函数的条件下,导出网络全局指数稳定的一个充分条件,得到的充分条件在实际应用中易于验证,且有较小的保守性,因而对网络的应用和设计具有重要意义.最后,一个数值实例进一步验证结果的正确性.

| Abstract: | In this paper, global exponential stability of Hopfield neural networks with time - varying delays is investigated by constructing suitable Lyapunov function and using Young inequality and Halanay inequality in connection with inequality analysis techniques , A new sufficient condition is obtained to guarantee global exponential stability of networks, The condition are easy to check in practice and impose less conservation. Thus, the obtained results possess importance significance in the application and design of networks, At last, an example is given to illustrate the application of our results. |
