This paper is concerned with the synchronization problem of a class of chaotic systems with uncertainties.A novel design method for the adaptive fuzzy synchronization is proposed based on a Takagi-Sugeno(T-S) fuzzy dynamical model.The proposed methods can be appliced not only to the chaotic systems with the same structures,but also to the chaotic systems with different structures.To demonstrate the effectiveness of our method,simulation results of synchronization are finally given for the Lorenz system and Rossler system.
