Design of feedback controller for functional projective synchronization of chaotic systems with disturbances

摘要: This paper considers the synchronization problem of chaotic systems with disturbance using a new feedback control scheme. Functional projective synchronization (FPS), which is a generalized synchronization concept recently developed, is investigated. Based on Lyapunov stability theory, a novel stability criterion for the synchronization between master and slave chaotic systems is derived. The proposed method is applied to unified chaotic systems and Chen-Lee chaotic systems in order to show the effectiveness of our method.
