利用LC滤波器实现延迟混沌及控制的电路实验

Experiment circuit of time-delayed chaos and chaotic control realized using LC filter

以Logistic延迟混沌系统为例,介绍了延迟混沌电路的设计方法.利用LC低通滤波器具有良好群时延特性来实现延时,改变电路中的参量,可以观测到电路由倍周期分岔通向混沌的道路.同时将限幅法用于控制该混沌电路中,得到多个不同的周期轨道.

Taking the Logistic time-delayed chaotic system as an example, a method of devising time-delayed chaotic circuit is introduced. Time delay is realized by means of a LC low pass filter with good group time delay, and the route from double period bifurcation to chaos is observed by changing some parameters of the circuit. The chaotic circuit is controlled by amplitude limiter, various periodical orbits are obtained.
