For a class of chaotic systems with unknown functions and disturbances, a synchronization controller based on the
adaptive fuzzy logic systems is proposed in this paper. Firstly, based on the universal approximation property of fuzzy logic
systems, the Mamdani type fuzzy logic system with the parameter adaptive laws is designed by utilizing the data information
sampled from the inputs and outputs of unknown functions in the chaotic systems. Then this fuzzy logic system is employed
to synthesize the drive-response synchronization controller with parameter adaptive laws. Finally, the simulation shows the
effectiveness of the proposed method.
