资料介绍

在三维Lü混沌系统的基础上加入一个反馈控制状态变量产生了一个新的超混沌系统。对该系统的耗散性、稳定性、 Lyapunov指数谱及分岔现象等基本动力学特性进行了仿真分析,证明了系统超混沌吸引子的存在性,并发现了改变反馈控制参数能够使系统从超混沌向混沌、周期轨状态进行转换的规律。同时,设计了一个模拟电路,实验中观察到的六种超混沌吸引子与仿真结果完全一致。

A new hyperchaotie system has been established by adding a feedback state variable based on a threedimension La chaotic system. Some basic dynamic characteristics such as dissipativity, stability, Lyapuno exponent speetrrm and bifurcation of this hyperchaotie system are theoretically analyzed. The simulation results demonstrate that the existence of hyperchaotie behaviors, and then find the fact that this system can transform from a hyperchaotie state to a chaotic state and a periodically state through changing the value of the feedback state variable. Moreover, an analog electronic circuit has been designed, and six heperehaotie attractors of this system are observed, which are in good agreement with the simulated results.
