Summary:In this contribution a control scheme for a class of fractional-order chaotic systems and its application in the synchronization and secure transmission of data problems is designed. The asymptotic stability of the synchronization error and the ultimate bound of the information recovery error are established employing the fractional Lyapunov direct method. The proposed sigmoid-like controller is used as input to the receiver system whose states are asymptotically synchronized with the transmitter system. The technique has been applied in the synchronization and secure communications of the incommensurate fractional-order Rössler and Chen systems.
