Acceleration and Deceleration Algorithm of Stepping Motor Based on Logistic Model

步进电机由于结构简单以及稳定性高的特点,被广泛应用于控制领域。步进电机的控制涉及到频繁的启停,速度以及加速度的突变会严重影响设备的寿命,需要进行速度规划,设计基于logistic模型的步进电机加减速算法,算法具有更强的可用性,调试起来也更方便,同时将传统的七段式S型加减速算法简化成五段式S型加减速算法,提高系统启动以及停止过程中的平滑性,防止发生失步、堵转和过冲。

Stepping motor is widely used in control field because of its simple structure and high stability.Stepping motor control involves frequent start and stop,sudden change of speed and acceleration will seriously affect the life of the equipment,which need velocity planning,this paper designs the acceleration and deceleration algorithm of stepping motor based on logistic model.At the same time,the traditional seven segment S-curve acceleration and deceleration algorithm is simplified into five segment S-curve acceleration and deceleration algorithm to improve the smoothness of the system during start-up and stop,and prevent out of step,locked rotor and overshoot.
