Abstract
A new steering control system of aluminum hot rolling mills has been developed. The features of the new system are as follows:
(1) The steering process is stabilized by the state feedback control which adjusts bending force using the signal of rolling load difference.
(2) After stabilization of the steering process, an integrate feedback controller which adjusts roll gap difference using the signal of the steering sensor, is designed to reduce the steady-state steering deviation.
The effectiveness of the new system has been demonstrated by the application for a real plant.
