  • ADHS - Switched system modeling and robust steering control of the tail end phase in a Hot Strip Mill
    IFAC Proceedings Volumes, 2016
    Co-Authors: Ivan Malloci, Jamal Daafouz, Claude Iung, Patrick Szczepanski
    Abstract:

    Abstract In this article, a robust steering control for the last phase of the rolling process in a Hot Strip Mill is proposed. This phase, called tail end phase, may be modelled as a linear switched system. The switchings make the system unstable and the task of the tail end steering control consists in guaranteeing the safety of the industrial plant. The control law has to take into account the physical variations of the rolled products and an uncertainty in the switching time. Simulation results concerning the ArcelorMittal Hot Strip Mill of Eisenhuttenstadt are presented.

  • Robust Steering Control of Hot Strip Mill
    IEEE Transactions on Control Systems and Technology, 2010
    Co-Authors: Ivan Malloci, Jamal Daafouz, Claude Iung, Remi Bonidal, Patrick Szczepanski
    Abstract:

    In this paper, a robust steering control is proposed as a means to guarantee the stability of a Hot Strip finishing Mill and improve its performances. The aim of the rolling process is to obtain a metal Strip which is uniform and at the desired thickness. The lateral movement of the Strip may reduce the quality of the product and damage the rolls. Hence, this displacement must be limited to improve process reliability. Since a Hot Strip Mill treats products with very heterogeneous characteristics, a significant database was created and divided into different families of products. A method for reducing the numerical complexity of the problem exploiting the relation between the different product parameters is also presented. This method yields a convex stabilisation problem. Hence, for each family, a different robust controller is designed. Simulation and experimental results concerning the ArcelorMittal Hot Strip Mill of Eisenhuttenstadt are presented.

  • Switched system modeling and robust steering control of the tail end phase in a Hot Strip Mill
    Nonlinear Analysis: Hybrid Systems, 2009
    Co-Authors: Ivan Malloci, Jamal Daafouz, Claude Iung, Remi Bonidal, Patrick Szczepanski
    Abstract:

    In this article, a robust steering control for the last phase of the rolling process in a Hot Strip Mill is proposed. This phase, called tail end phase, may be modelled as a linear switched system. The switchings make the system unstable and the task of the tail end steering control consists in guaranteeing the safety of the industrial plant. The system involves a two time scales dynamics. Hence, the singular perturbation method is used in order to design the control law. The controller has to take into account the physical variations of the rolled products and an uncertainty in the switching time. Results concerning the ArcelorMittal Hot Strip Mill of Eisenhuttenstadt are presented.

  • Robust steering control of Hot Strip Mill
    2009
    Co-Authors: Ivan Malloci, Jamal Daafouz, Claude Iung, Remi Bonidal, Patrick Szczepanski
    Abstract:

    In this article, a robust Hot Strip Mill steering control is proposed in order to guarantee the system stability and to improve its performances. The rolling process consists in crushing a metal Strip between some rolls for obtaining a product with constant and desired thickness. The quality of the rolled products and the safety of the production process are linked to the lateral movement of the Strip in the line. Then, the main task of the steering control consists in reducing this displacement. A Hot Strip Mill treats products with very different characteristics. Then, the products are divided into several families, with reference to their physical characteristics, and the stabilisation problem is formulated as a convex problem. Finally, for each family, a different robust controller is designed. Simulated and experimental results concerning the steering control in the ArcelorMittal Hot Strip Mill of Eisenhuttenstadt are presented.
