Hybrid synchronization of n-scroll chaotic chua circuits using adaptive backstepping control design with recursive feedback

In this paper,the hybrid synchronization is investigated for n-scroll chaotic chua circuit (wallace et al. (2001)) using adaptive backstepping control design based on recursive feedback control. our theorems on hybrid synchronization for n-scroll chaotic chua circuits are established using lyapunov stability theory. the adaptive backstepping control links the choice of lyapunov function with the design of a controller and guarantees global stability performance of strict-feedback chaotic systems. the adaptive backstepping control maintains the parameter vector at a predetermined desired value. the adaptive backstepping control method is effective and convenient to synchronize and estimate the parameters of the chaotic systems. mainly,this technique gives the flexibility to construct a control law and estimate the parameter values. numerical simulations are also given to illustrate and validate the synchronization results derived in this paper.
