基于AT91SAM9261的步进电机S曲线加减速控制研究与实现
Research and Implementation of S Curve Acceleration and Deceleration Control for Step Motor Based on AT91SAM9261
摘要
Abstract
When the step motor accelerates or decelerates to S curve, there is no soft impact, which is good for highspeed motion. The embedded ARM soc AT91SAM9261 was adopted as the control platform to study the pulse generating mechanism. The algorithm and equation of S curve was analyzed and derived. Moreover, the paper also described the process of discretization which converts curve to pulse. Next, the possible cases of acceleration and deceleration status in actual motion, which were determined by real time motion control, were listed. Finally, the pulse testing indicates that the algorithm and motion control methods of acceleration and deceleration proposed are feasible and can be applied to motions with various parameters as well as improve the efficiency and stability of step motor.
