Design of Fuzzy PID Controller for Hot Rolling Looper System

摘要

In this paper,a fuzzy PID controller is designed for hot rolling looper system in accordance with the transfer function model.First,we deign fuzzy rules,using min-max- gravity fuzzy reasoning and the defuzzification the method of center-of-gravity,then good PID parameters are obtained.At last,we compare the performance of conventional PID with the proposed fuzzy PID,the results show that the performance of the looper control system can be obviously improved,especially existing disturbance for looper system.
