Quasi-synchronization of Different Fractional-Order Chaotic Systems with External Perturbations and Its Application

In this paper, based on the fractional comparison principle, a scheme for quasi-synchronization of different fractional-order chaotic systems with external perturbations is constructed. Subsequently, the scheme is applied to achieve quasi-synchronization between fractional-order Lorenz and Chen systems with external perturbations. The proposed method in this paper can be easily extended to achieve quasi-synchronization for other different fractional-order chaotic systems. Meanwhile numerical simulation results show the effectiveness of the derived results.
