Robust shape control in a sendzimir cold rolling steel mill
The shape control problem for a Sendzimir 20 roll cold rolling steel mill is characterised by operation over a wide range of conditions arising from roll changes changes in rolling schedules and changes in material gauge width and hardness Previous approaches to the problem suggest storing a large number of precompensator matrices to cater for the full range of operating conditions.
