Original abstract
The paper presents the use of a solidification model coupled with control algorithms for optimization of secondary cooling. The solidification model provides data to control algorithms, which evaluate an actual thermal state of a strand and control casting parameters such as cooling intensity in secondary cooling zone. The paper aims at our recent development of advanced control methods for secondary cooling. A fuzzy logic and model predictive control approaches are tested and compared to traditional PID regulation and cooling curve control. A study case with a dynamic change of the casting speed, which may occur in production, is used to assess control capabilities of developed algorithms. Simulation results show the developed control and regulation tools are robust and effective for control of secondary cooling in continuous casting.
Czech abstract
Článek se zabývá srovnáním různých metod pro řízení sekundárního chlazení plynulého odlévání oceli. V článku jsou prezentovány přístupy fuzzy řízení a prediktivního řízení pomocí počítačového modelu. Tyto metody a jejich použití jsou následně srovnány s běžně používaným řízením pomocí chladicích křivek a PID regulace.
