| 摘 要： | 首先用主动-被动分拆法研究Henon同步,实现了全同参数的同步,可用于保密通信,而对非全同参数出现失同步.由于实际中产生连续作用下的耦合同步并非易事,因此,还实现了对Henon映射非连续作用(间隙耦合)形式下的混沌同步,只要同步相超过作用的临界值,即可实现准确同步.将这两种方法应用到类Henon映射,得到了类似的结论.

| Abstract: | We have realized Henon synchronization via APD synchronization, in which we acquired synchronization of identical systems. The nonsynchronization of unidentical systems makes the method potentially useful in secure communication. Because chaos synchronization by coupling continuously is not easy, we realized Henon synchronization by occasional coupling synchronization. As long as the synchronization phases exceed the critical value, synchronizing Henon mapping by occasional coupling can be obtained. The same results have also been achieved by synchronizing Henon like. |
