Abstract
This paper considers the gauge control problem in tandem cold rolling. A robust multivariable solution is proposed via the H∞ loop shaping method of McFarlane and Glover (1990), which combined with a gain scheduling technique enables the control of the mill from thread speed to full speed. Improvement over a representative industrial controller is observed from nonlinear simulation results
