摘要: 为了研究混沌神经网络的抗扰动能力,在Chen’s混沌神经网络中引入了三角函数扰动项,研究了带扰动的Chen’s混沌神经元模型,给出了该混沌神经元的倒分岔图和Lyapunov指数图,分析了其动力学特性。基于该混沌神经元模型,构造了带扰动的Chen’s混沌神经网络,并将其应用于函数优化和旅行商问题(TSP)。仿真结果表明:Chen’s混沌神经网络有一定的抗扰动能力。

Abstract: In order to study the anti-disturbance of chaotic neural network,the trigonometric function disturbance is introduced into Chen’s chaotic neural network and chaotic neural units with disturbance are studied.The reversed bifurcation and the maximum Lyapunov exponent are given and the dynamic system is analyzed.Based on the neuron model,the Chen’s chaotic neural network with disturbance is made and used to functions’ optimization and Traveling Salesman Problems(TSP).The simulation results indicate that Chen’s neural network has some capability of anti-disturbance.
