基于电流控制的混合式步进电动机微步驱动技术研究

Study of Hybrid Stepping Motor Subdivided Driving based on Current Control

对电流控制型的二相混合式步进电动微步驱动技术进行了深入研究。探讨了检测波形的非完整性和给定信号波形的设定。在分析快续流和慢续流控制方式的基础上,提出了一种混合续流的新控制方法。仿真结果证明其控制效果明显。还讨论了小电流误差的问题及对策。

In this paper,hybrid stepping motor subdivided driving based on current control was studied. The discrete current sampling wave and the disposal of reference wave vere also discussed. After analyzed the quick-current reflowing and the slow-current reflowing control methods ,the author brings forward a mew method named mixed-current reflowing control. Its effectiveness is verified through simulation. The low current error and measures were discussed also.
