Using an Adaptive Sliding Mode Variable Structure Controller with Sector Nonlinear Input to Achieve Chaotic Systems Synchronization

a method based on adaptive sliding mode variable structure controller is presented for synchronization of a class of chaotic system with perturbations and parameter mismatch. The controller is more robust to perturbations, parameter mismatch and inputs sector nonlinearity. Moreover, no restrictive assumption is imposed on the system. Thus the adaptation range of the proposed method becomes broad. Theoretical analysis and simulation results illustrate the validity.
