摘要
该文提出了用PLC的定时中断实现PI控制的通用程序框架,并结合电机速度闭环控制,讨论了在PLC中精确采样周期的实现、实际速度值的采样实现及PI控制算法的具体实现。
This paper presents a general program frame of closed loop control with PLC,and discusses how to realize the PI algorithm with PLC used as a controller along with a high speed counter used for feedback and the RS-485 used as a motor driver port.
