Claim 0:
1. A resonance suppression control device configured to control suppression of vibrations in a resonance frequency of a control target, the resonance suppression control device comprising:
a plurality of feedback loops configured to provide negative feedback of an output of the control target to an input side in accordance with a plurality of vibration modes of the control target, wherein
each of the plurality of feedback loops includes a band-pass filter, a phase compensator, and an amplitude adjuster, the band-pass filter being configured to extract one or more vibration modes from the plurality of vibration modes,
the band-pass filter and the phase compensator function as differentiators, and
at least one of the band-pass filter, the phase compensator, or the amplitude adjuster includes a parameter that is variable in accordance with the resonance frequency.
