APPARATUS AND METHOD FOR AUTOMATICALLY SUPPRESSING RESONANCE OF SERVO SYSTEM USING ADAPTIVE NOTCH FILTER

摘要

According to an embodiment of the present invention, disclosed is an apparatus for automatically suppressing resonance of a servo system using an adaptive notch filter which comprises: a resonance detection device which senses resonance and suppression of resonance from a current command generated by a servo control device which generates the current command; a frequency estimation device which estimates the frequency of the current command; and an adaptive notch filter which filters the current command by applying the frequency, estimated by the frequency estimation device, as a notch frequency. According to another embodiment of the present invention, disclosed is a method for automatically suppressing resonance of a servo system using an adaptive notch filter, which comprises the following steps: sensing resonance from the current command generated by the servo control device; estimating a frequency of the current command; and filtering the current command by applying the frequency, estimated by the frequency estimation device, as a notch frequency.;COPYRIGHT KIPO 2017
