Abstract :
This paper investigates the problem of generalized synchronization of two hyperchaotic systems via fuzzy control method. Based on the exact T-S fuzzy models of these two hyperchaotic systems, a simple fuzzy controller is designed to realize the robust synchronization of the two nonidentical hyperchaotic systems. The stability criteria of the synchronization error systems are derived by applying Lyapunov stability theory and linear matrix inequality (LMI) technique. Simulation results demonstrate the validity of the proposed fuzzy synchronization scheme.
