超混沌系统与混沌系统相比动力学特性更加复杂
但是目前大多数超混沌系统参数范围较小
提供的密钥空间较小
而且在系统参数发生改变时系统容易跳出混沌状态.针对这个问题
本文提出了一个新的超大范围超混沌系统.该系统在参数属于1
10时都表现为超混沌状态.理论分析了新系统的基本动力学行为
包括系统相图、平衡点、Lyapunov指数谱和分岔图.本文进一步用FPGA实现了该混沌系统
给出了系统参数分别为5、100、1000和10时
在示波器上捕捉到的-相轨迹图
验证了该超大范围超混沌系统的FPGA可实现性.
The hyperchaotic system has more complex dynamic characteristics than the chaotic system. However
most hyperchaotic systems currently have a small parameter range and provide a small key space
and the system easily jumps out of the chaotic state when the system parameters change. Aiming at this problem
a novel super-wide range hyperchaotic system is proposed in this paper. The system is hyperchaotic when the parameter c is1
10. The basic dynamics behaviors of the novel system are analyzed theoretically
including system phase diagrams
equilibrium points
Lyapunov exponent spectrums and bifurcation diagrams. In this paper
the chaotic system is implemented by FPGA
and the x-z phase trajectories captured on the oscilloscope are given when the system parameters c are 5
100
1000 and 10 respectively
verified the FPGA achievability of the super-wide range hyperchaotic system.
