Serial antiresonance compensator with notch filter [articol] /

Abstract

The application of serial antiresonance compensator with notch filter in the speed control system for the cancellation of the undesirable effects of torsion resonance on the motor shaft has been discussed in this paper. Antiresonance compensator is realized as a serial connection of the notch filter and the proportional controller. The notch filter is used to eliminate the resonant picks on the Bode plots of the open loop system response. More efficient time response is attained by adding the proportional controller in the direct loop.
