摘要
本文通过分析步进电机运行时统组中电流的变化规律,给出一种检测换相点的电路,分析了转速、超前角和时间延迟之间的关系,进而给出了具体的PI闭环控制的硬件框图和控制程序框图。
Through discussing the varying character of current of stepping motor winding when it is running,the article shows akind of cireuits for examining and measuring the alter - chase point, and analyses the relationship between the speed, exceedingangle and delay time. Furthermore, it gives the specific framewok of hardware and cotrolling program of PI cloed loop control.
