Abstract:
A printing apparatus, a feeding apparatus, and a feeding control method supply an object accurately to a target position by servo control even though the load abruptly changes. In this printing apparatus, the conveyance position and conveyance speed of a printing medium are detected by using an encoder. The conveyance target position of the printing medium is generated at a predetermined period, and corrected. A PWM signal is generated on the basis of the generated or corrected conveyance target position, and the conveyance position and conveyance speed of the printing medium which are detected and fed back. A DC motor is servo-controlled by the PWM signal. At this time, the generated or corrected conveyance target position is compared with the detected conveyance position of the printing medium. Control is made to perform correction in accordance with the comparison result.
