Rolling Mill AGC Control System Design Based on Auto Disturbance Rejection Controller

Abstract:

Be aimed at the difficulty problems that entrance variation in thickness and hardness variation change a lot、back-up roll deflection、roller thermal expansion、the variation of lubricating fluid and flow compensation indeterminacy of servo mechanism in the system of steel plate strip, anti-interference controller is applied to rolling mill AGC control system for the first time in this paper. Theory analysis and simulation experiment demonstrate that rolling mill AGC based on Auto Disturbance Rejection controller can solve the above difficulty problems which convention rolling mill AGC control system can’t solve, the proposed system possess excellent dynamic property and static state property.
