A dynamic optimization method is developed for temperature control of steel slabs in a continuous reheating furnace. The work was stimulated by the need for furnace control concepts that are computationally undemanding, robust, accurate, and capable of non-steady-state operating scenarios, where the properties and the temperature goals of slabs may vary(More)
A flexible solution method for the initial-boundary value problem of the temperature field in a one-dimensional domain of a solid with significantly nonlinear material parameters and radiation boundary conditions is proposed. A transformation of the temperature values allows to isolate the nonlinear material characteristics into a single coefficient of the(More)
In gas-fired industrial furnaces, gas burners are typically used for heating of a load. The heating process inside the furnace has a strong influence on the product quality of the load. For accurate control of the load temperature, highperformance subordinate control of the mass flow of natural gas and air to the burners is crucial. For this purpose, a(More)
Gas-fired industrial furnaces are used to heat products to a predefined temperature level. As the temperature of the load as well as the composition of the flue gas are crucial for many applications in industry, the controllers of burners have to ensure a given heat input and air-fuel ratio. As a basis for such controllers, an accurate mathematical model of(More)
The annealing process plays an important role for the product quality of steel strips. To achieve a high product quality, an accurate temperature control is essential, which typically requires information about the temperature evolution inside the strip annealing furnace. However, usually only a few temperatures at discrete points in the furnace can be(More)
The most common and well proven control strategy for thickness control in industrial rolling mills is the automatic gauge controller (AGC). However, it is still unclear how to use AGC for the control of asymmetries in lateral direction. How should the controller react to different thickness estimations at both sides of the mill? Such laterally asymmetric(More)
