摘要
设计了一种步进电机控制系统。该系统通过运动控制卡产生脉冲和方向信号。用MicrosoftVisualBasic编辑界面程序。调用控制卡中的运动函数库,动态改变脉冲频率,控制电机的转向和转速,从而在开环控制状态下实现对步进电机的控制。既提高了实时性和快速性,又方便实用。
A control system of step-motor is designed. In the system signals of pulse and directon are produced through control-card. The interface program is edited using Visual Basic Language, through using movement function library in control -card and altering pulse frequency dynamicly, the direction and the velocity of the motor are controlled to realize the control to step-motor in opening loop state. It not only can enhance the real time property and the speediness property, but also is convenient and useful.
