摘要:
步进电机速度控制S曲线随电机型号及外力负载不同而改变。在获取光纤定位单元所用步进电机速度控制S曲线时,对传统S曲线生成方法进行优化和改进,采用三次方程的S曲线。通过对光纤定位单元进行走位实验,对比发现定位精度有了明显提高。该方法不仅能够很容易获取不同步进电机在加减速控制中的S曲线,而且在S曲线等脉冲离散过程中,可以跳过共振带而获得最佳曲线离散频率组,适用性好。
Abstract:
The stepper motor's S-curve varies with types of stepper motors and mechanical loads. In the process of acquiring a stepper motor's S-curve for a fiber positioning unit, this paper optimizes and improves the traditional method of obtaining S-curve and uses the S-curve with cubic equations.The accuracy of positioning of fiber unit was clearly improved as a result of a positioning experiment on a fiber positioning unit. The results show that, this method not only can make it easier to obtain different stepper motor's S-curve in the acceleration and deceleration control, but also can get the best curve discrete frequency groups and skip the resonance band in the process of pulse discretization.Thus, this paper concludes that the method can be applied in a wide number of contexts.
