Modified projective synchronization of uncertain unified chaotic systems via backstepping approach

摘要

This paper focuses on modified projective synchronization of uncertain unified chaotic systems via backstepping approach. A parameter observer is designed to identify the unknown parameter of unified chaotic systems and a novel backstepping control method is presented for synchronizing two identical unified chaotic systems with each other. Numerical simulations are shown to verify the feasibility and effectiveness of the proposed control technique.
