The Design of Mill Automatic Gauge Control System Based on the Fuzzy Proportion Integral Differential Controller

This paper presents a self-adjusting fuzzy proportion integral differential (PID) controller for high non-linear, time-varying automatic gauge control (AGC) System of rolling mills. For the adjusting of the PID parameters is difficulty. The three parameters of PID controller can be adjusted adaptively on line based on the fuzzy rules. The simulation shows that the fuzzy self-adjusted PID controller has good dynamic quality. The control system has short response time, small overshoot, highly steady state behavior, good dynamic and static performance by comparing with the traditional PID controller.
