二阶连续型Hopfield神经网络的平衡点及全局指数稳定性
Globally exponential stability and equilibrium points for second order continuous Hopfield neural networks
【摘要】 讨论输出响应函数为非光滑的二阶连续型Hopfield神经网络的平衡点的存在和唯一性,得到了该类网络平衡点存在并且唯一的两个充分条件.同时,该类网络的唯一平衡点全局指数稳定的一个新判据被获得.作为特例,输出响应函数为非光滑的一阶连续型Hopfield神经网络的一些新判据也被得到.这些新判据是文献[3]的诸结果的改进.
【Abstract】 Two sufficient criterions are found for both the extence and uniqueness of equilibrium point of second order continuous Hopfield neural networks,in which all output respond functions are nonsmooth.At the same time,a new result of the global exponential stability of the equilibrium of such networks is proved.As a special case,some new criteria are obtained for the corresponding one-order Hopfield neural networks.And these results are an improvement of paper [3].
