摘要: 针对一类具有部分未知转移概率的离散时延Markovian跳跃神经网络系统,建立了更具一般代表性的随机神经网络动力学模型,研究其渐近稳定性问题。假定转移概率部分元素未知,系统中的不确定为范数有界,基于Lyapunov稳定性理论,通过构造适合的Lyapunov-Krasovskii泛函并利用随机分析方法,给出了离散Markovian神经网络系统全局渐近稳定的充分性判据。通过Matlab的LMI工具箱,求解线性矩阵不等式对判据进行检验,新的判据减少了结果的保守性。数值仿真算例验证了所给判据的有效性。

Abstract: The analysis problem of asymptotic stability for a class of uncertain neural networks with Markovian jumping parameters and time delays was addressed. The general representative dynamic stochastic neural network model was established. The considered transition probabilities were assumed to be partially unknown. The parameter uncertainties were considered to be norm-bounded. Based on Lyapunov stability theory, by constructing a suitable Lyapunov-Krasovskii function and using the stochastic analysis method, some sufficient criteria for the stability of discrete Markovian neural networks was derived. Through the Matlab LMI toolbox, solving a set of linear matrix inequalities to test criterion, the new criterion reduced the conservatism of the results. A numerical example illustrates the effectiveness of the proposed theory.

Key words: neural networks, Markovian jumping parameters, partly unknown transition probabilities, asymptotic stability
