Notch Fliters in Control Applications by Galil

There are some applications in which the standard tuning procedure using the PID filter of the controller cannot completely eliminate the resonance in a system. Resonance occurs when the natural frequency of a system is excited in a way that increases the amplitude of oscillation. This is usually due to system compliance, such as a mechanical coupling or inherent motor characteristics.
