中文摘要
      对双向联想记忆神经网络研究了平衡点的鲁棒稳定性. 该网络的参数不确定, 并且有时变时滞. 当神经网络的激励函数满足Lipschitz连续性条件时, 通过选取合适的Lyapunov-Krasovskii函数, 建立了两个全局鲁棒稳定判据. 由于这些判据考虑了神经元激励作用和抑制作用对网络的影响, 他们和时变时滞的数值无关, 并且易于使用内点算法进行检验. 在注释中和已有的结果进行了对比. 两个数值例子展示了所得结果的有效性.
英文摘要
      The robust stability of equilibrium point is studied for bi-directional associative memory neural networks with parameter uncertainties and time-varying delays. When the activation function satisfies the condition of Lipschitz continuity, two sufficient conditions are established for the globally robust stability of the equilibrium point by suitably choosing Lyapunov-Krasovskii functional. The obtained results, which take account of the effects of neural inhibitory and excitatory on neural networks, are independent of the sizes of the time-varying delays and are easy to be checked by the interior-point algorithms in MATLAB toolbox. They are compared with prior results in a remark, and are demonstrated by two numerical examples for their effectiveness.
