Abstract:The problem of finite-time synchronization control for a class of four-wings chaotic master-slave systems with unknown external disturbances is studied in this paper.Firstly,the uncertainties of the four-wings chaotic systems are dealt with by virtue of the adaptive fuzzy control approach.Secondly,based on Lyapunov’s finite-time stability criterion,a finitetime synchronization controller is designed,which enables the state synchronization between the master system and the slave one can be accomplished in a limited time.Finally,the effectiveness and robustness of the proposed approach are verified by numerical simulation.
Keywords:four-wings chaotic systems  fuzzy control  adaptive control  finite-time synchronization  Lyapunov’s stability
