A method is presented here to direct the chaotic motion towards desired low-period motion by using notch filter output feedback control in lots of chaotic systems. The mathematic and physical mechanism of this method is also discussed based on Melnikov Method which is perturbation criteria for chaos. The control results of some typical chaotic systems are given, which has been shown that the method of controlling chaos can be easily and practically realized in physical systems. The method, furthermore, can be applied to achieve control for hyper-chaotic systems.
