摘要
直接数字频率合成(DDS)技术是目前广为应用的一项频率合成技术,它具有频率转换时间短、频率分辨率高、可编程等特点.正是利用直接数字频率合成技术产生步进电动机控制系统的步进脉冲.试验证明这种方法具有稳定、可靠、精度高等优点,非常适合那些对速度要求精确控制的系统.
DDS （direct digital synthesis） is a sort of frequency synthesis technique,which has advantages such as short frequency conversion time, high resolution in frequencies , programmability and so on. This paper puts forward a method to produce step pulse in the stepper-motor control system by using of DDS technology. The experiment proves that the method is steady, reliable, and suitable to those systems requiring accurate speed control.
