Design and Implementation of Intelligent Tension Control System for Amorphous Narrow Strip

In the heat treatment process of amorphous narrow strip, aiming at the problems of low tension control precision, poor stability and low intelligence, an intelligent tension control system was designed. After analyzing the factors that affected the control accuracy and stability, the rubber roller part was designed, the installation accuracy of rubber roller was proposed, and the improved PID control algorithm was adopted to establish a closed-loop feedback control model with PLC as the controller, guide wheel type tension transmitter as the feedback element and servo motor as the actuator, so as to realize the effective tension control with high accuracy, high stability and intelligence. The system operation results show that the tension control error is limited within 3%.
