摘要
针对步进电机按特定的升降速曲线进行控制无法充分发挥步进电机最大的驱动能力的情况,提出一种步进电机最佳升降速的控制方法,并给出计算步进电机的最佳升降速率曲线的算法和步骤。为了验证控制方法的有效性,构建一个以32位微处理器ARM7(LPC2114)为控制器的实验装置,实验结果表明控制方法能够充分利用步进电机的驱动能力,减少步进电机到达稳定转速的时间,提高驱动系统的快速性。
The method of using the particular speedup＆speeddown curve to control the stepper motor can not make the best use of its driving power. This paper introduces another method to reach the optimum speedup＆speeddown of the stepper motor and provides the way and the step to calculate the optimum rate of speedup＆speeddown curve. To testify the validity of this method, a experimental device by using of a 32 -bit microprocessor ARM7 （LPC2114） is builded. The experimental results shows that this method can make good use of the driving power of the stepper motor and reduce the time for the stepper motor to reach the stable speed, thus improving the rapidity of the driving system.
