Projective synchronization of chaotic time-delayed systems via sliding mode controller

In this paper a new method for projective synchronization of hyperchaotic models with different parameters based on sliding mode is developed. By using Lyapunov stability theory the stability of error dynamics is guaranteed. The synchronizing method is then compared from various viewpoints. Moreover, effect of the differences in parameters values is also included in our discussion. Furthermore, message encoding is considered based on synchronization. Also, numerical simulations are given to show the effectiveness of the method.
