Experimental considerations upon the optimal control of reversing rolling mills

The paper introduces some experimental results of applying the theory of optimal control of high power reversible drives in a rolling mill from the steel plant of Hunedoara, Romania, starting year 2001. As the result of these experiments was a series of (predictable) conclusions that are drastically limiting the possibilities of a strictly optimal control, we suggested an expert structure meant to lead to favorable sub-optimal work conditions, which are achievable in practice.
