摘要
提供了一种经济型数控工作台闭环控制的解决方法，给出了硬件控制结构及控制算法，对提高数控工作台的精度具有指导作用。
Nowadays, the open loop control system is widely used in the control of economic type NC working table. However, a more effective close loop control system in this field is suggested with the structure of hardwares and the controlling algorithms provided. The idea presented contributes to the improvement of the precision in the NC working table.
