Abstract
A control device includes: an angular velocity detection unit that detects an angular velocity of a motor; a vibration component removal unit that removes a vibration component in a predetermined band from the angular velocity detected by the angular velocity detection unit by filtering; and a current command calculation unit that calculates a current command value of a drive current for driving the motor according to a torque command value and the angular velocity from which the vibration component has been removed by the vibration component removal unit.
