Projection synchronization of a class of complex chaotic systems with both uncertainty and disturbance

This paper mainly investigates the projection synchronization of complex chaotic systems with model uncertainty and external disturbance through linear feedback control method and uncertainty and disturbance estimator (UDE)-based control method. First, a linear feedback controller is used to control a class of complex nominal chaotic systems to achieve projection synchronization. Then, a UDE-based controller is used to realize the projection synchronization of complex chaotic systems with both uncertainty and disturbance. Finally, numerical simulations verify the feasibility and effectiveness of the control method.
