Abstract
This thesis is concerned with the automatic control
systems used in hot strip mills. A general description of
a hot strip mill is firstly given, followed by a description
of usage of digital process computer in controlling a complete
hot strip mill.
The automatio gauge eontrol system, which is one of
the most important systems in the mill, is described using
the different techniques of tension and screwdown control.
The A.G.e. system employing screwdown control is studied in
details, using analogue computer simulation techniques, and
the system responses are illustrated.
The mathematical model of the finishing mill is then
derived, followed by the development of the linearized state
space model. The transportation delay is approximated, and
other simplifying assumptions are used to reduce the model
order so that it would be feasible to apply modern control
theory.
The optimal control design of the system is obtained
in the form of an optimal feedforward-feedback controller Computational algorithms were developed and numerical
results were obtained for the optimal controls and
responses-
