In a resonance suppression control device that controls suppression of vibrations in a resonance frequency in each vibration mode of a control target having a plurality of vibration modes, a configuration that is simple, can be easily mounted, and can suppress vibrations in a resonance frequency in the plurality of vibration modes is provided. A control device 2 is a resonance suppression control device that controls suppression of vibrations in a resonance frequency in each vibration mode of a control target P having a plurality of vibration modes. The control device 2 includes a plurality of feedback loops 11 and 12 that provide negative feedback of output of the control target P corresponding to the plurality of vibration modes to an input side. The plurality of feedback loops 1 1 and 12 respectively include band-pass filters 51 and 61 that extract one or more vibration modes from the plurality of vibration modes, phase compensators 52 and 62, and amplitude adjusters 53 and 63. The band-pass filters 51 and 61 and the phase compensators 52 and 62 function as differentiators.
