摘要: 介绍了一种新的驱动方式.通过数值计算和李雅普诺夫指数的分析可以看出, 选择适当的驱动变量只驱动一个格点上的非线性振子, 可以实现两个系统所有对应格点上的非线性振子的混沌同步.讨论了影响混沌同步的各种因素.

关键词: 混沌, 李雅普诺夫指数, 同步

Abstract: A new driving fashion is introduced.The synchronization of spatiotemporal chaos of two arrays of coupled nonliear oscillators is achieved only by driving one oscillator. Also discussed is the Lyapurov exponentsof two nonliear systems and illustrated numerically the factors influencingon the synchronization.

Key words: chaos, Lyapurov exponent, synchronization
