| Abstract: | A scheme,which can be used to control a time-delayed (lagged) chaotic system to a periodic state,is proposed based on the feedback signal with notch amplitude-frequency characteristic. With the theory of Hopf bifurcation of a time-delayed system,the necessary condition to control the system is derived. By the experiments of numerical computation and the circuit simulation on the PSPICE,the validity of theoretic analysis and the efficiency of this scheme to control a time-delayed chaotic system are identified. |
