Backstepping a pproach for realizing the strict-feedback chaos systems lag-synchronization control

This paper researches on the Lag-synchronization of strict-feedback chaos systems. We present a systematic design procedure to Lag-synchronization a class of chaotic systems in the strict-feedback form. This approach needs only a single controller to realize Lag-synchronization no matter how many dimensions the chaotic system contains. the Chua chaotic system of the three-dimensional strict-feedback system is taken as a concrete example to illustrate the procedure of designing. Numerical simulations are given to illustrate the effectiveness of the methods.
