Sensorless Driving Control to Achieve both Residual Vibration Suppression and High-precise Positioning in a Stepping Motor with a Full-step Drive

Abstract

Stepping motor has been widely used for both factory automation (FA) and office automation (OA), because it is able to achieve high-accuracy positioning by open loop control. This paper mainly presents the suppression control of residual vibration for the feeding part of chip taping machine. In this paper, a novel system that can perform high-speed movement and high-accuracy positioning while suppressing residual vibration is proposed, even if the load to a feeding part inhomogeneously varied when the stepping motor is driven intermittence.
