An adaptive method to parameter identification and synchronization of fractional-order chaotic systems with parameter uncertainty

In this paper, parameters of a fractional-order chaotic system are identified via a robust recursive error prediction method in presence of uncertainty. A generalized ARX structure has obtained by discretization of a continuous fractional-order differential equation defines the identification model. After identifying parameters of system, we use concept of active control method to synchronize two identified fractional-order chaotic systems. The validity of results are demonstrated through an example and also compared with other method. (C) 2015 Elsevier Inc. All rights reserved.
