摘要
引入非线性状态反馈控制器生成了一个新的四维连续自治超混沌系统,这个系统可以生成四翅膀超混沌吸引子。通过计算机仿真证明了这个超混沌吸引子的存在,观察Lyapunov指数图和系统的分岔图可以清楚地看到从超混沌到混沌以及周期轨迹的分岔过程;设计电路进行了硬件实验验证。仿真结果与硬件实验结果相一致。
A new four-dimensional continuous autonomous hyperchaotic system was generated by the method of introducing a nonlinear state feedback controller in the paper,the system could generate four-wing hyperchaotic attractor.The existence of the hyperchaos was proved by computer simulation.The bifurcation routes from hyperchaotic,chaotic and periodic evolutions were observed from Lyapunov exponent spectrum and bifurcation diagram.Moreover,the designed electronic circuit was verified with hardware experiment.The results of numerical simulation of the new hyperchaotic system were in accord with the results of hardware experiment.
