Correlatively Coupled Synchronization of Discrete Mapping Chaotic Systems

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.
