摘要：This paper derives new adaptive synchronizers for the hybrid synchronization of hyperchaotic Zheng systems (2010) and hyperchaotic Yu systems (2012). In the hybrid synchronization design of master and slave systems, one part of the systems, viz. their odd states, are completely synchronized (CS), while the other part, viz. their even states, are completely anti-synchronized (AS) so that CS and AS co-exist in the process of synchronization. The research problem gets even more complicated, when the parameters of the hyperchaotic systems are not known and we handle this complicate problem using adaptive control. The main results of this research work are established via adaptive control theory andLyapunov stability theory. MATLAB plotsusing classical fourth-order Runge-Kutta method have been depictedfor the new adaptive hybrid synchronization results for the hyperchaotic Zheng and hyperchaotic Yu systems.
