摘要
基于一个新三维混沌系统,通过引入非线性控制器,构造出一个新的四维超混沌系统,并对该系统的动力学行为进行了研究,包括它的Lyapunov指数谱、分岔图等.分析表明,新的四维系统随着新引入的参数变化呈现周期、复杂周期、混沌及超混沌动力学行为;设计的硬件电路的实验结果也证实了相关结果.
A new four-dimensional continuous-time autonomous hyperchaotic system is proposed in this paper, which is built by adding a nonlinear controller to a three-dimensional continuous-time autonomous chaotic system. The hyperchaotic system is analyzed by studying the Lyapunov exponent spectrum and bifurcation diagram. The system will take on periodic and complex periodic, chaotic and hyperchaotic behaviors with change of the parameter. Also, an electronic circuit is designed and realized, the experimental results verify the conclusions.
