摘要
介绍一种采用DDS技术来控制步进电动机精确定位的方法,给出了DDS原理及其实现。在硬件上引入反馈,实现了指数型降速曲线。完成后的设计参数可以方便调整,性能稳定,可扩展性好,通用性强。
A method for stepper motor orientation controlling based on DDS technology is introduced.The element of DDS and its implement are described.There is a feedback in this system, and the curve is exponent.The parameters in the programs are very convenient for change. Good performance, expansibility and reusable are obtained.
