Abstract： The winding tension of the wire drawing machine is an important factor in the process of drawing.In order to solve the problems of controlling tension of drawing machine，the tension control system of drawing machine based on PLC and PID control algorithms was investigated. After the analysis of tension causes and control，the relationship between the winding speed and tension was established. A method was presented to tension control system of drawing machine based on PLC. The tension control system of drawing machine was evaluated and tested on the Matlab Simulink. The experimental results show that the tension control system of drawing machine can achieve good effect. It has fast response，small overshoot，high accuracy and stability.
