Elongation control played a vital role for the production of cold-rolled strip. In the production process, especially during tension disturbances or parameter variations, the conventional PID control method can not meet the actual demand well. Therefore, the intelligent control algorithm was introduced in this paper. A fuzzy self-adaptive PID closed-loop control strategy which combines the fuzzy control algorithm with the conventional PID control algorithm was applied to elongation control system. It is proved in the simulation study that the fuzzy self-adaptive PID control system has both high dynamic performance and static performance as well as strong robustness, which can greatly improve control accuracy and anti-jamming capability of elongation control system of the tension leveller.

The control of simulated beer production line is implemented based on a Q series PLC controller of Mitsubishi company. The mathematical modeling method and the self-adaptive control strategy are introduced. The Mitsubishi PX-Developer software is adopted to design, run and debug online the PID and self-adaptive PID controller. Performance comparison between the two kinds of control strategy is made. It is shown that the self-adaptive PID control algorithm has the superiority.
