抄録

Stepping motor has been widely used for both the factory automation (FA) and the office automation (OA), because it is able to achieve high-accuracy positioning by open loop control. This paper studies on the suppression control of residual vibration for the feeding part of chip taping machine. Since the load is inhomogeneously changed at the feeding part, it is difficult to derive the optimum pulse timing for suppressing the residual vibration into the allowed constant range. Therefore, in this paper, a system that can perform high-speed movement and high-accuracy positioning is proposed, even the load changes inhomogeneously when the stepping motor is drove intermittence. By designing optimum pulses that can stabilize into the reference position after performing an overshot or undershoot, we achieved the fine positioning without vibration and steady error.
