Projective Synchronization for a Class of Unknown Chaotic Systems Based on Adaptive Fuzzy Control

摘要

A practical projective synchronization problem for master and slave chaotic systems with uncertainties and external disturbances was addressed in this study. Practical projective synchronization between the master chaotic system and slave systems was achieved by an adaptive fuzzy controller. Then the underlying parameter adaptation and the stability analysis were carried out based on Lyapunov based technique. In the design of the proposed projective synchronization method, the knowledge of the uncertainties and the external disturbances were not required. Finally, simulation results were given and one could see the effectiveness of the proposed practical projective synchronization method.
