步进电机加减速控制新方法的研究

摘要

Based on further study of step motor on acceleration and deceleration control method,a new five phased S-curve acceleration and deceleration method was proposed.The parameters of S-curve could be calculated according to a set of displacement and time,then the PLC could complete the acceleration and deceleration control of step motor based on the discrete method of S-curve.The results showed that the method could make sure the speed and acceleration was continuous,also restrained phenomenon of out-of-step and overshoot,avoiding the mechanical flexible impact and extending the life of the system.%通过对步进电机加减速控制方法的深入研究,提出了五段S型曲线的加减速方法,根据设定的位移和时间,计算出S型曲线的参数,根据S型曲线的离散方法,实现PLC控制步进电机完成加减速控制.结果表明:这种加减速算法能够保证速度、加速度的连续,有效抑制失步和过冲现象,避免了机械柔性冲击,延长系统寿命.
