摘要:为了提高步进电机驱动系统运行的速度稳定性,通过对其影响因素的分析,根据步进电机细分驱动原理,给出了基于最小二乘法原理的细分驱动波形综合修正算法。该算法跳过了建立复杂驱动系统模型的过程,通过系统理想和实际的输入、输出误差,建立函数,得到实际空间角度的修正量,将其转化为相应的电角度后,获得修正波形。实验结果证明,电机驱动系统在修正波形的驱动下,速度稳定性得到了明显提高。

Abstract: In order to improve the velocitys stability of driving system powered by stepper motor, a method based on the principle of leastsquares algorithm to correct the fractionized driving wave was put forward, according to the theory of fractionized driving and the analysis of the factors influencing the velocity stability. The method leaped over the process of establishing the complex model of the system, constituted the correcting function to get the dimensional anglecorrection through the error between the ideal and real inputoutput. After the correction was transformed into electrical angle, the optimized wave was found. The results of the tests show that the system driven by the optimized wave runs much more smoothly.
Key words: driving system powered by stepper motor; velocity stability; driving voltage wave; the principle of leastsquares algorithm
