Based on the stability theory of fractional order linear systems,a novel method combining feedback control with active control was proposed for the lag synchronization of fractional order chaotic systems. By designing a proper controller the lag synchronization of fractional order chaotic systems was converted to the asymptotic stability of the fractional order linear error systems at origin. The numerical simulation results on fractional order Chen system verify the effectiveness of the proposed method.
