Abstract: Based on nonlinear dynamics theory and Lyapunov stability theorem, the synchronization between chaotic systems and between hyperchaotic systems were studied, respectively. Focusing on deriving and proving the synchronization controller’s expressions, the synchronization control strategy studied in this paper improved the flexibility in both chaos signal’s generation and hardware’s realization, and the result was verified by numerical simulations.
