摘　　要：通常对步进电机的驱动控制是采用开环控制的,但是当步进电机工作在具有运行的止动点时,步进电机就需要根据当前的状态自动调节自身的运行速度。为了实现对具有止动点步进电机的自动控制,采用了一种通过角度反馈实现步进电机控制的方法,可以使步进电机自动寻找最小最大止动点,并且可以在运行接近止动点时实现缓慢可靠的停止。The common method for driving step motors is based on open-loop control, but when the stepper motor work in a condition that has stop point under running, the stepper motor will need to adjust its speed according to the current state. In order realize the automatic control to the stepper motor with stop point, a method of use angle feedback to realize the control of stepper motor is put forward in this article, the stepper motor could find the minimal and maximal stop point automatically, and can be slowly and reliably stop the motor when closing to the stop point under running.
