APPARATUS FOR AUTOMATICALLY DETECTING AND SUPPRESSING RESONANCE IN SERVO SYSTEM USING ADAPTIVE NOTCH FILTER AND METHOD THEREOF

摘要

In one embodiment of the present invention, a resonance sensor for detecting resonance and resonance suppression from a current command generated in a servo controller for generating a current command, a frequency estimator for estimating a frequency of the current command, and a frequency estimator for estimating a frequency And an adaptive notch filter for filtering the current command by using the notch frequency. The automaresonance suppression apparatus of the servo system using the adaptive notch filter is disclosed.In another embodiment, the method further comprises: sensing resonance from a current command generated in the servo controller; estimating a frequency of the current command; and estimating a frequency estimated by the frequency estimator as a notch frequency of the adaptive notch filter, The method comprising the steps of: detecting a resonance frequency of the servo system;
