基于数字PID算法的台达运动控制器在音叉多线切割机上的应用

Application of the Digital PID Algorithm Based Delta Motion Controller to the Tuning Fork Multi- wire Cutting Machine

在连续一时间控制系统中，PID控制器在各类自动化系统中应用得非常广泛。其设计技术成熟，长期以来形成了典型的结构，参数整定方便，结构变化灵活，能满足一般的控制要求。数字PID控制比连续PID控制更为优越，因为计算机程序的灵活性，很容易克服连续PID控制中存在的问题，经修正可得到更为完善的数字PID算法。

In the continuous-time control system, PID controller is widely used in various automation systems, PID controller has typical structure, and it is of advantages of mature design technology, convenient parameters setting and flexible structure variation, which can meet the general control requirements. The digital PID control is more superior than the continuous PID control due to the flexibility of computer program that would be apt to overcome the existing problems in the continuous PID control, the more perfect digital PID algorithm can be obtained via revising.
