Multivariable Controller Design for Hot Rolling Mill

Författare

Summary, in English

This paper concerns the controller design for the hot rolling mill at the Danish Steel Works Ltd. The design is done using derived dynamical multivariable models. The main objective of the design is to separate the two sides of the rolling mill. This is obtained by first linearizing the positioning system using feedback linearization and then using eigenspace design on the linearized multivariable system. To ensure that the design is stable, the stability of the system is investigated using the small gain theorem. The performance of the controller is evaluated using estimated models based on data from the plate mill.
