Abstract
A method, apparatus, and program for driving a motor in a feedback control system, capable of suppressing oscillation of the motor are disclosed. A motor drive controller includes a drive motor, a detector, and a motor drive controller. The drive motor drives a moving body around a target moving speed. The detector detects a current moving speed of the moving body and output it as a detector pulse signal. The controller calculates a difference between the current moving speed and the target moving speed, calculates a control value based on the difference, calculates a pulse rate of a drive pulse signal based on the control value after having controlled the control value to be within a predetermined value, and feedback controls the drive motor based on the pulse rate.
