“…Thus, it appears to be structurally stable. These ideas have motivated the authors to construct a real mathematical model for synchronization of two different fractional-orders chaotic systems.The pioneering work of Pecore and Corrall [1] introduced a method about synchronization between identical or nonidentical system with different initial conditions, which has attracted a great deal of interest in various fields due to its important applications in ecological systems [2], physical systems [3], chemical systems [4], modeling brain activity, system identification, pattern recognition phenomena, and secure communications [5,6].In recent years, various type of synchronization scheme such as linear and nonlinear feedback synchronization [7-9], back stepping control [10] , active control [11][12][13], adaptive control [14][15][16][17][18][19][20][21], sliding mode control [22,23], projective synchronization [24,25], and function projective synchronization [26,27] have been successfully applied to chaos synchronization. In 1999, Mainieri and Rehacek [28] for the first time present the projective synchronization method, which is one of the most noticeable one because it can obtain faster communication with its proportional feature [29,30].…”
