Abstract
A motor control device controls a motor of a mechanical device. The motor control device includes a command value calculation unit that calculates a command value for controlling the motor, and a disturbance observer unit for estimating a disturbance applied to the mechanical device, based on the command value and rotation information of the motor, and to correct the command value based on the disturbance that is estimated. The disturbance observer unit has parameters that are adjusted to compensate for effects of the disturbance having a specific frequency that is an object of suppression. The parameters are adjusted such that a disturbance, applied to the mechanical device after effects of the disturbance are compensated for, has frequency characteristics corresponding to antiresonance characteristics of the mechanical device.
