Abstract
A motor control device includes a vibration-damping-control setting unit to designate one of a plurality of candidate frequencies of a vibration-damping frequency, a signal-for-estimation computing unit to output, based on an operation signal related to a controlled object, a signal for estimation in which signal components of the other candidate frequencies excluding the designated one candidate frequency are reduced from a vibration component of a control system, and a resonance-characteristic estimating unit to estimate one resonance frequency from the output signal for estimation. The vibration-damping-control setting unit designates each of the candidate frequencies individually as one candidate frequency and sets, in a feedforward control unit, each of resonance frequencies estimated by the resonance-characteristic estimating unit related to the individually designated each one candidate frequency.
