Notch filter feedback control for chaotic systems
凹槽滤波反馈控制混沌系统

A new method is presented to achieve control over chaotic motion in the perturbed planar Hamiltonian system using notch filter output feedback control. Based on Melnikov's method which is perturbation criteria for chaos, the suitable parameters of notch filter are computed to direct the chaotic motion towards desired low-period motion, the average method, moreover, is introduced to analyze the stability of the controlled system. And numerical simulation results are provided to demonstrate the effectiveness of Melnikov's analysis.
