Abstract

This paper utilizes an adaptive synchronization control principle based on OGY idea to realize the synchronous of two cubic chaotic systems which have different initial value and parameter. Then theory and numerical simulation shows that the control strategy needs to select right error Regions’ Radius  and feedback coefficient . The paper also utilizes control principle of lag synchronization to realize the lag synchronization of cubic chaotic system and Logistic map. Then theory and numerical simulation shows that state variables of Logistic map track state variables of cubic chaotic system strictly.
