摘要: 构建了Coullet混沌系统的硬件实验电路,改变系统的参数,可以从示波器上观察系统从稳定周期状态演变到混沌状态的分岔过程.采用非线性反馈控制方法实现了对Coullet混沌系统的有效控制,改变反馈控制增益,可以将Coullet系统从混沌状态控制到稳定的周期状态.

关键词: 非线性反馈控制, 混沌, Coullet系统

Abstract: The experimental circuit of Coullet chaotic system is structured. As the parameter of Coullet system is changing, the bifurcate process form the steady periodic state to chaotic state is observed by using oscillograph. The system is effectively controlled via nonlinearly feedback. As the value of feedback gain is changing, the system can form chaotic state to the steady periodic state.

Key words: nonlinearly feedback control, chaos, Coullet chaotic system
