Chaos synchronization has been an interesting and active research field since the seminal work of Pecora and Carroll[1].From then on, chaos synchronization develops extensively and intensively due to its potential applications in secure communication and control processing[2].Recently, synchronization of chaotic fractional order differential systems becomes a new challenging and significant problem.Owing to the different definitions of the fractional order differential equation (FODE) from the classical ordinary differential equation (ODE), lots of methods and results of chaos synchronization in the ODE systems can not be directly used in the chaotic FODE systems.
