Generalized Synchronization of Discrete Systems
-
摘要: 讨论两个离散系统之间的广义同步.通过构造合适的非线性耦合项,导出了驱动响应系统获得广义同步的充分条件.在一个正不变的有界集上,许多混沌映射满足这些充分条件.通过3个例子,说明了充分条件的有效性.Abstract: Generalized synchr onization of two discrete systems is discussed.By constructing appr opriately nonlinear coupling terms,some sufficient conditions for determining the generalized synchronization between the drive and response systems were derived.In a positive invariant and bounded set,many chaotic maps satisfy the sufficient conditions.The effectiveness of the sufficient conditions is illustrated by three examples.
