摘　　要：利用Matlab GUI建立了混沌系统实验仿真平台,可以在该平台界面输入和改变参数,分析各参数对实验结果的影响,也可以自己设计和改变混沌系统,进行深度学习和探索。利用该平台可以得到多维混沌吸引子的分解图像和数据,直观地观察投影图和时域图、Lyapunov指数、功率谱、分维数等混沌指标。用仿真平台研究非线性电路中的混沌现象,能准确地观察到混沌吸引子的行为特征,结果与理论分析十分吻合。By using Matlab GUI,a set of chaotic system and experimental simulation platform is established. The users can enter and change the parameters in the interface,intuitive analysis of the impact of each parameter on the experimental results. The chaotic system for deep learning and exploration can also be designed and changed. Platform of chaotic system and simulation experiment can obtain multidimensional chaotic attractor of the decomposition of image and data,it is convenient to directly observe the time domain and projection map, and can calculate the Lyapunov exponent and power spectrum, dimension chaotic indexes. The chaotic phenomena in nonlinear circuit are studied from two angles of theoretical system and experimental simulation. The simulation experiment and theory are very consistent, which can accurately observe the behavior characteristics of the chaotic attractor.
