传统步进电机控制通常采用反馈设备和非传感方法,是有效的实现带有安全需求、危险状况或高度要求的运动应用的方法。
大多数基于步进电机的系统,一般都运行在开环状态下,这样可提供一个低本钱的方案。 事实上,步进系统可进步位移控制的的性能,且不需要反馈。但是,当步进电机在开环时运行,在命令步幅和实际步幅之间会有同步损耗的可能。
闭环控制,是传统步进控制的一个部分,能有效地提供更高地可靠性、安全性或产品质量。在这些步进系统中,反馈设备或间接参数传感方法的闭环能进行校正或控制失步、监测电机停滞,以及确保更大的可用转矩输出。近期,步进电机的闭环控制(CLC)还能帮助执行智能分布运动架构。
方法和益处
很多技术都可用于获得步进电机的CLC位移、速度和转矩控制。按照可控性从低至高的顺序,包括:核步法、反电动势(back electromotive force (emf)检测、或全伺服法。

nal Instruments(NI)公司产业控制产品经理Rahul Kulkarni提到了一些采用闭环步进控制的原因与适用状况:
● 无需进行参数调整;系统
很轻易建立,通常可以实现免维护;
● 在连续移动进程中,答应利用断点触发摄像机或数据采集设备;
● 控制位置过冲,特别在不答应的状况,例如,纳米制造或半导体行业;
● 在运动结束时纠正位置。
