摘 要: 通过对一个光滑三维二次混沌系统上引入一个新的状态反馈控制器,构造出一个新的四维超混沌系统。详细地分析了该系统平衡点的性质、超混沌吸引子相图、Lyapunov指数和分岔图等基本动力学特性。数值模拟结果表明,新的四维系统能随着参数变化呈现出周期态、拟周期态、混沌态和超混沌态等丰富的动力学行为。最后设计了硬件电路实验,也很好的证实了相关结果。 A new 4D(four-dimensional) hyperchaos system is built up by introducing a state feedback controller into a smooth quadratic three-order chaotic system,and its basic dynamical properties are studied in detail,such as the feature of equilibrium,the hyperchaos attractor,Lyapunov exponent and bifurcation diagram.Numerical simulations show that this new 4D system could,when the parameter varies,exhibits rich dynamic behaviors including periodic,complex periodic and hyperchaotic states.Also,the electronic circuit for the smooth quadratic hyperchaotic system is designed.Finally,the hardware circuit experiment on the chaotic system is implemented,and the related results are verified.
