Fractional order sliding mode control based chaos synchronization and secure communication

The present work demonstrates a novel fractional order sliding mode controller for synchronization of fractional order chaotic systems and its use in secure communication. First, the existence of the chaotic behaviour is ensured for the autonomous chaotic system under consideration and then a sliding mode controller is designed in order to make the system follow a designated state trajectory. This idea is then extended towards the making of a chaotic transmitter and a chaotic receiver. It is shown that, when synchronized, this can be used to securely transmit an analogue signal.
