| 摘 要： | 目前在混沌同步的研究中，Ｃｈｕａ’ｓ电路是研究得比较深入的混沌系统，本文对两个Ｃｏｌｐｉｔｔｓ振荡器的同步进行了探讨，对系统的某一状态变量差进行离散反馈滤波后，可以使两个结构相同的Ｃｏｌｐｉｔｔｓ振荡器达到同步，并讨论了反馈因子、采样脉冲宽度及参数失配对混沌同步的影响，应用本同步方法可以节约系统资源、减少干扰对同步信号的影响，文中给出了仿真验证结果。

| Abstract: | At present, in the area of research of chaotic synchronization, Chua's circuit is used as the chaotic system which has been discussed rather thoroughly. The present paper presents a study of synchronization of two Colpitts oscillator. The synchronization of two identical structure chaotic systems is attained. The effect of feedback, the pulse duration as well as the parameter on chaotic synchronization are all discussed. Using the synchronous method, the system resource is saved and the effect of disturbance on synchronization is reduced. The synchronization method is illustrated by numerical simulation experiment. |
