Abstract

See full text

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, and can suppress vibrations in a resonance frequency in the plurality of vibration modes is provided. A control device is 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. The control device includes a plurality of feedback loops that provide negative feedback of output of the control target corresponding to the plurality of vibration modes to an input side. The plurality of feedback loops respectively include band-pass filters that extract one or more vibration modes from the plurality of vibration modes, phase compensators, and amplitude adjusters. The band-pass filters and the phase compensators function as differentiators.
