摘要:
There are provided: a plurality of notch filters which are arranged inside a control system for feedback-controlling a moving operation of a moving section of a motor and attenuate signal components having near frequencies with a notch frequency at a center in an input signal; a plurality of oscillation extracting filters which are set with different frequency bands as being corresponded to the respective notch filters and extract oscillating components in the set frequency bands from a speed detection signal; and a plurality of notch controlling sections which are arranged with respect to the respective oscillation extracting filters and control the notch frequencies of the corresponding notch filters so as to decrease amplitudes of the oscillating components extracted by the oscillation extracting filters.
