摘要
单向耦合驱动同步法可实现耦合环形腔激光器映象格子模型与耦合声光双稳态映象格子模型时空混沌的广义同步.数值实验表明最大条件李雅普诺夫指数为负,可以实现时空混沌广义同步,给出了实现同步的最小耦合强度,利用辅助分析法证明了异构系统的广义同步.
The generalized synchronization of spatiotemporal chaos can be realized by unilateral coupling between laser oscillation in a ring cavity spatial extended system and acousto-optic bistable spatial extended system. Numerical simulation shows that the generalized synchronization can be obtained if the maximum condition Lyapunov exponent is negative. The minimum coupling strength is showed for achieving synchronization. We use the auxiliary approach to investigate the generalized synchronization.
