Abstract: The wrap-up tension system adopts traditional control results in integral calculus backlog of controller,control quantity exceeding the limit,system bigger overshoot,or even a system surge,this is absolutely not allowed in production.Therefore,the integral-separation control algorithm is applied to programming controller to control tension.When compared with conventional control algorithm,it improves control performance effectively.It is simulated by MatLab with built-in Simulink software package.The subsystem package of integral-separation is accomplished and the simulation model of tension control system established.The results of simulation indicated that this method improves the accuracy and efficiency greatly,reduces the overshoot and is highly valued for engineering application.
