In this paper, fractional-order Chen system is studied. A predictor-corrector method is applied to design the controller. This method is used because the dynamical characteristics of fractional-order Chen system are obtained using multistep approximation. The designed controller is also applied to synchronize chaotic fractional-order systems in drive-response structure. Numerical simulation and circuit design of the systems demonstrate the effectiveness and feasibility of the proposed scheme.
