Abstract
This paper deals with the problem of shape (or flatness)
control for Sendzimir 20-roll cold-rolling steel mills. Such
mills, with a variety of shape actuators, offer the control engineer
considerable choice in the configuration and design of a shape control
system. In addition, the Sendzimir mill is a reversing mill, with
shape measurement devices at either end of the mill, providing a
facility for feedforward of incoming shape disturbances. The multivariable
problem presented by the mill has a significant singularity
problem, which is tackled in this paper using a variety of approaches,
motivated by both practical (operational) considerations
and formal theoretical procedures. A final challenge lies in the desire
to economize on the number of controllers required to cover
the mill over its wide range of operating conditions. The paper
compares and contrasts various controller possibilities and is intended
to provide a “cookbook” of shape control tools and strategies
for Sendzimir mills.
