摘要：The projective reduced-order synchronization of two different chaotic systems with different orders is investigated based on the observer design in this paper. According to the observer theory, the reduced-order observer is designed. The projective synchronization can be realized by choosing the transition matrix of the observer as a diagonal matrix. Further, the synchronization between hyperchaotic Chen system (fourth order) and R?ssler system (third order) is taken as the example to demonstrate the effectiveness of the proposed observer. Numerical simulations confirm the effectiveness of the method.
