Abstract: An effective active backstepping method is applied to projective synchronization of two different chaotic systems. The proposed scheme offers a recursive procedure where active control is designed by selecting a series of Lyapunov functions to quickly stabilize the error system at equilibrium. Numerical simulations for projective synchronization of the Lorenz system and Chen's system demonstrate effectiveness of the method.

Key words: projective synchronization, scaling factor, active backstepping control
