离散神经网络指数稳定改进条件
Improved Exponential Stability Criteria of Discrete-time Neural Network
【摘要】 研究了一类时滞离散神经网络指数稳定及鲁棒稳定问题.结合线性矩阵不等式技术,构造了一个新的广义李亚普诺夫函数,得到了新的指数稳定条件.数值算例表明与以往文献中的结果相比,新准则具有较弱的保守性.
【Abstract】 The problem of exponential stability and robust stability for a class of discrete-time neural network with time-varying delay is investigated.By constructing a new augmented Lyapunov-Krasovskii function,some new improved stability criteria are obtained in forms of linear matrix inequality(LMI).Numerical example shows that compared with some previous results in literature,new criteria are less conservative.
