基于Simulink的四翼超混沌系统的仿真与分析

Simulation and Analysis of a Four-Wing Hyperchaotic System Based on Simulink

在一个四翼超混沌系统的微分数学模型基础上,利用Matlab软件和Simulink工具箱混合编程进行了仿真和模拟,通过改变控制参数的值,得到相应的结果变化情况,证明了该系统中存在分叉现象。在假设控制参数一致而稍微改动系统的初始条件,发现其动力学行为特性完全不一样,表明了系统对初值的极其敏感性。

On the base of the mathematical model of four-wing hyperchaotic system, using Matlab and Simulink toolbox to simulate and changing the control parameters, we can prove the bifurcation exists in the system. And if we only change initial values, we can find dynamic behavior is significantly different, which shows the sensitivity of chaotic system to the initial conditions.
