Multivariable controller design for hot rolling mill
(1998) In IEEE Trans. on Control Systems Technology 6(2). p.304-312- Abstract
- This paper describes a controller design for a hot rolling mill. The main purpose of the algorithm is to improve the control of the cross-width thickness profile of the plates. This is obtained by designing a controller which makes independent thickness control possible at the two sides of the rolling mill. This is obtained by first linearizing the positioning systems using feedback linearization and then using linear quadratic eigenspace design on the linearized multivariable system. Integral control is included to ensure zero stationary thickness error. The design is done using derived dynamical multivariabl models. To ensure that the design is stable, the stability of the system is investigated using the small gain theorem. The... (More)
