研究了驅動和響應系統為相同混沌系統、初值或參數不同時的同步問題。提出了關聯耦合同步方法，通過對驅動與響應系統進行耦合，實現兩個混沌系統的同步。并且，可以實施間歇性控制，減少控制代價。以logistic映射為例進行了計算機仿真研究，仿真結果證實了該方法對實現離散映射混沌系統同步的有效性。

Abstract The synchronization of the drive system and response system which are described by the same chaotic systems but have different initial values or parameters is studied in this paper. A correlative coupling method of synchronizing chaos is proposed. Coupling these two systems each other can synchronize the drive system and response system. Furthermore, the intermittent control can be used to reduce the control cost. A computer simulation on two logistic maps is conducted. The simulation results illustrate the effectiveness of the proposed method for realizing the synchronization of discrete mapping chaotic systems.
