摘　　要：在一个四维二次超混沌系统的基础上,通过改变其中一个状态变量构造成一个新的超混沌系统,并且通过模拟开关自动切换状态变量,实现原超混沌系统和新的超混沌系统的自动循环切换。对新的超混沌系统的Lyapunov指数和分岔图进行了分析,通过数值仿真得到了相图;设计了一个模拟电子电路,电路仿真实验可以观察到两个超混沌系统自动切换的相图。仿真结果表明,该设计达到了较理想的效果。Based on a four dimensional quadratic hyperchaos system,a novel hyperchaos system was constructed by changing one of the state variables,and the automatic cycle switching between the orginal hyperchaotic system and the new hyperchaoitc system was achieved through switching the state variables automatically by the analog switch.Lyapunov index and bifurcation diagram for the new hyperchaotic system are analyzed.A phase diagram was obtained with numerical simulation.An analog electronic circuit was designed.The phase diagram of automatic switching between two hyperchaotic systems was observed in circuit simulation experiments.
