Projective Synchronization of Piecewise Nonlinear Chaotic Maps

With wide applications in secure data transmission and encryption, synchronization of chaotic systems is an interesting concept and has accordingly received special attention among nonlinear systems. Here, we propose an appropriate controller for synchronizing one-parameter families of piecewise nonlinear chaotic maps using a projective synchronization method. First, we present synchronization in coupled chaos discrete-time systems using the master-slave method. Using the principle of the stability of the Lyapunov function, we design a proper controller for achieving projective synchronization of piecewise nonlinear systems. Finally, we demonstrate the applicability of the proposed scheme with simulation results.
