Abstract

A new synchronization control method for chaotic system, which only needs one scalar time series of the master system to reach the synchronization, is present in this paper. It is robust to noise and the synchronization can be obtained in a high level noise. This method may have practical application in secure communications or optical communication because it only needs one scalar time series and it can be controlled in the background of noise. Finally, numerical examples are given for the typical Lorenz chaotic system to illustrate the effect of the proposed method..
