In order to ensure the accuracy and efficiency of production, a tour motor and a full-closed loop of the integral-separation PID control algorithm based on PLC is proposed in the end. The result showed that the tension control system bottles the tension perturbation, solved the problem of the tension oscillation caused by the whole closed-loop, and achieved the desired requirements on process control. That method provides a high efficient multi-wire cutting and high-precision operation way for reference in similar research field.
