Research of tension Control System of paper tape in fruit-cultivating bag machine

According to the tape tension requirements in the course of fruit-cultivating bag machine running, fuzzy self-adaptive PID controller is applied to tension control system and mathematics model is founded. The structure and controlling rules of PID controller has been analyzed. Process simulation is completed and proves that the method satisfied the request of moderate and constant tension, and the system has the advantage of rapid detection, rapid response, small overshoot, small steady-state error, which increases production efficiency.
