Hybrid adaptive function projective synchronization of a hyper Lüchaotic system

Abstract

In this paper, a hybrid adaptive function projective synchronization of a hyper Lü chaotic system is investigated. Firstly, according to the Lyapunov stability theory and Pecora-Carroll synchronization criterion, the controller and adaptive rate of these two kinds of synchronization methods are analyzed and designed. Then a new hybrid adaptive projective synchronization method is proposed. Finally, in order to prove the effectiveness of the proposed scheme, the comparison between those controllers is studied by simulation example.
