Abstract
A motor control device including: a current command value calculation unit configured to calculate a current command value for driving a motor; a current value detection unit configured to detect current flowing through the motor; a current control unit configured to output a first voltage command value according to deviation between a current detected value, the current detected value being a detected value of current detected by the current value detection unit, and the current command value; a voltage disturbance control unit configured to calculate a second voltage command value by adding output from a delay element to the first voltage command value and also input the second voltage command value to the delay element; and a driving circuit configured to drive the motor, based on the second voltage command value.
