Transmission synchronization of multiple memristor chaotic circuits via single input controller and its application in secure communication.

This article mainly studied the transmission synchronization of multiple memristor chaotic circuits by using a single input controller strategy. For transmission synchronization model, the definition of synchronization is established, and based on the stability of minimum phase system, the sufficient conditions of system stability are obtained to ensure that the system error curves of multiple memristor chaotic circuits can maintain asymptotical synchronization. Furthermore, the results of synchronization circuit experiment illustrate that the designed controller works well for the synchronization of multiple memristor chaotic circuits. Finally, the results of secure communication experiment based on transmission synchronization show that the scheme is feasible. • A transmission synchronization scheme is investigated by a single input control method. • The circuit of transmission synchronization is implemented. • An encryption technique illustrates the effectiveness of secure communication.
