摘要/Abstract

摘要：

构造了一个具有四翼超混沌吸引子的非线性系统，通过对Poincaré截面、吸引子和Lyapunov指数等分析揭示新系统中超混沌吸引子的存在.根据Routh-Hurwitz准则发现，系统有1个不稳定鞍点、6个不稳定焦点和2个稳定焦点.分析了参数c变化对系统动力学的影响，数值仿真显示该系统发生了典型的倍周期分岔现象，最终通往混沌.所提出的四翼超混沌系统在保密通信和信息安全等领域有很好的应用前景.

Abstract：

A nonlinear system with four-wing hyperchaotic attractors is built,and its hyperchaotic characteristics by the analysis of Poincaré sections,the power spectrum and Lyapunov exponents are verified in this paper.We have studied,the stability for equilibrium points of the system,and found that the system has an unstable saddle point,six unstable focuses and two stable focus.The impact of parameteron system dynamics is discussed,and numerical simulation results show that there is a typical double period bifurcation phenomenon,which results in chaos eventually.The proposed hyper-chaotic system with four wings has potential applications in the fields of secret communication and information safety.
