“…Chaos control and M a n u s c r i p t 2 synchronization is extensively and intensively studied since Pecora and Carroll [1] introduced a method to synchronize two identical chaotic systems with different initial conditions. During the last decades, control and synchronization of chaotic systems has become one of the most interesting subjects in chaos theory, most synchronizing techniques, such as linear and nonlinear feedback synchronization [2][3][4][5][6], impulsive synchronization [7][8], adaptive synchronization [9][10][11][12][13], observer based control method [14][15][16], and so on, have been designed for unidirectionally coupled systems.…”
