Abstract
The design of shape control systems for producing
flat metal strip products is discussed. Static and
dynamic models for a Sendzimir mill are described briefly.
Optimal dynamic output feedback solutions are presented
for the shape control system design. The optimal control
solutions provide guidance on the best structure to be
used for shape control. It is shown that by judicious
choice of the performance criterion weighting matrices
particularly simple controllers may be derived; dimension
reduction by parameterisation is also shown to result in a
simplification to the controller structure.
The effect of nonlinearities in the actuators is
discussed, a linear approximation being used for design
purposes.
A variety of simulation results are presented showing
the transient response and the shape control performance
of the multivariable system. The effect of mismatch is
also demonstrated, that is, using the controller for a
mill schedule other than the one for which it was designed.
