摘要
提出了用条件熵来测定双向耦合混沌系统的广义同步,随着耦合强度的增大,当条件熵有一突出的最小值出现时表明两系统达到广义同步.为了证明这种方法的有效性,将这种方法用于Rssler-Lorenz与Rssler-Rssler混沌系统的双向耦合情况,数值模拟结果表明该方法非常有效且具有较强的鲁棒性.
The conditional entropy is used to assess the generalized synchronization of bidirectionally coupled chaotic systems. By increasing the coupled strength, the generalized synchronization appears when there is a sharp minimum of the conditional entropy. We apply this criteria to the case of the coupled Rossler-Lorenz and Rossler-Rossler system to test our method. Numerical results show that it is very effective and robust.
