This study focuses on the necessity of designing state observers to be used in controller synthesis
for rolling processes. This is motivated by the fact that using several kinds of sensors for measuring all of
process variables is technically and economically avoided. On the other hand, using exact measurement in
feedback control systems could considerably improve the quality of products. In other word, there is a trade-off
between high quality and the implementation limitations, managed here by developing rolling state observers.
The proposed observers estimate the states not measured directly by the installed sensors. This technique is
applicable to both hot rolling and cold rolling processes. Simulation results demonstrate the performance of the
proposed estimation algorithm.
Key words: Estimation error, feedback control, mathematical model, rolling mill, state observer, ,
