Abstract :
A new projective synchronization in coupled fractional order chaotic Chen systems is studied. First, an approximation integer order system for the fractional order Chen system is constructed. Then, since the scaling factor of PS (projective synchronization) is predicted hardly, a control algorithm is thus proposed to improve on the projective synchronization in the new integer order systems. This control scheme can be used in some secure communication systems. Illustrations are also given to show the rightness of the theoretical analysis and the effectiveness of the method proposed.
