摘要
本文结合电机速度闭环控制 ,提出了用PLC的定时中断实现闭环控制的通用程序框架 ,阐述了用PLC实现闭环控制的关键技术 ,包括速度闭环的系统组成。
In this paper, a general program frame of closed loop control with PLC is provided and how to realize PI algorithm with PLC is discussed, in which PLC is used as controller, high-speed-counter is used for feedback ,RS485 is used for motor driver port
