Abstract:
A motor control device includes: a motor-current detection unit; a rotational-angular-speed calculation unit for calculating a rotational angular speed of a motor; a rotational-angle-change-amount calculation unit for multiplying the rotational angular speed by a predetermined time so as to calculate a motor-rotational-angle change amount within a predetermined time; a basic-drive-value calculation unit for calculating a basic drive value for driving the motor; a correction-value calculation unit for calculating a correction value for correcting the basic drive value based on the motor current and the motor-rotational-angle change amount; a correction unit for evaluating the motor drive value by correcting the basic drive value by the correction value; and a drive unit for driving the motor by using the motor drive value evaluated by the correction unit.
