摘 要: 首先,运用Banach不动点定理,证明了这类系统存在平衡点,且平衡点是唯一的。然后,综合运用Lyapunov泛函方法以及一些不等式变换技巧,通过引入一系列参数,给出了系统在唯一平衡点处的全局指数稳定的充分条件。值得指出的是:该充分条件与系统所带的时延无关,并且对已有文献的研究结果进行了延拓。通过实验验证了此研究结果的可靠性。
关 键 词: 人工智能;计算机神经网络;脉冲;Banach不动点定理;指数稳定性;唯一平衡点

Abstract: First, the Banach's fixed-point theorem is used to establish a criterion for the existence and uniqueness of an equilibrium point of such neural networks. Second, by combining the Lyapunov functional method and some inequality techniques, accompanied with the introduction of a set of parameters, a sufficient condition of the global exponential stability of the unique equilibrium for the above mentioned systems is given. It should be mentioned that this condition is independent of the associated delays, and it is an extension of some previously known results. Finally, this criterion is justified via numerical examples and simulation experiments.
Key words: artificial intelligence; computer neural networks; impulses; Banach’s fixed point theorem; exponential stability; unique equilibrium point
