We consider the synchronization problem of a class of first-order differential-delay chaotic systems.We utilize time-delay fuzzy logic systems to approximate continuous nonlinear time-delay functions,so that the precise mathematical model need not be knownAdopting the adaptive fuzzy control method,we construct a class of state feedback controllers which can render the closed-loop error systems to be asymptotically stable.We carry out simulations of synchronizing Mackey-Glass and logistic chaotic systems,and the results are reasonable.
