摘　　要：深入研究了基于电流控制的二相混合式步进电动机的微步驱动技术。探讨了检测波形的非完整性以及给定信号的波形设定。对快续流和慢续流控制方式的特点进行了分析,并针对两者的不足之处,提出了一种混合式续流的新控制方法,仿真结果验证了该新控制方法的有效性。另外,还讨论了小电流的误差问题及其对策。The two-phase hybrid micro-stepping drive technology based on motor current control is studied. The non-complete characteristics of the test wave as well as the wave reset of the given signal are discussed.After analyzing the quick-current reflowing and the slow-current reflowing control methods,a new method of mixed-current reflowing is brought forward. The simulation results show thai this control method is effective. The low current error and measures are also discussed.
