Servo-control System Design of Automatic Production Line Based on PLC and HMI

摘要

Automatic production line includes machinery, electric, control, communication and other multi-disciplinary technologies and knowledge. It is an ideal training platform for students majored in mechatronics and electric automation. In the designing of platform, however, the difficulty lies in the precise delivery and position control of linear guide rail system. To address this problem, this paper aims at designing an AC servo-control system based on PLC, AC servo driver, servo motor and human-machine interface (HMI) and elaborates the principle of servo-control system, circuit design and software design. The system will achieve reliable delivery and precise positioning with position error less than 1 mm, which, with great application value, will meet the actual demand from industrial production.
