摘 要: 该文针对一个带自反馈的多时滞环状神经网络系统,在整个参数空间中,分区域系统完整地讨论了系统平凡解稳定与不稳定的条件,并根据正实部特征根个数依参数变动的变化规律,给出了不同参数条件下平凡解的相应最大稳定区域边界,改进和完善了先前的结果. A system of ring neural network with self-feedback and multiple delays is considered. Conditions for the stability and unstability of the trivial solution of this system are completely represented in a parameter space.According to the regulation of the variation of the number of eigenvalues with positive real parts,for different parameters,the authors investigate the boundary of the largest stability set,improve and complete the former conclusions.
