4Chaotic Synchronization Principle and Method

Due to the extremely sensitive initial value, researchers once thought it is impossible to control chaos. Until 1990, American scientists, Ott, Grebogi, and Yorke, proposed the OGY method to realize chaos control [12]. In the same year, Pecora and Carroll proposed a self-synchronizing method for chaos [10], and the synchronization between two chaotic systems is realized by using the drive–response method for the first time [94]. The breakthrough research has broken the traditional concept that chaos movement is not controllable and dangerous. It is proved that chaos can not only be controlled and synchronized, but also it is the basis of information transmission and processing. So it can be used in ...
