The Web Winding System (WWS) knows several constraints such as the thermal effects caused by the frictions, and the mechanical effects provoked by metal elongation, that generates dysfunctions due to the influence of the process conditions. A major objective in the web winding system control design is
  • To obtain a precise thickness, with the best possible regularity when a sudden constraints occurs;

  • To achieve stable rolling and ensure strip quality.

This work presents the conception of a new law of nonlinear control of the WWS. This is the backstepping method with introduction of integral actions. Furthermore, the simulation under the MATLAB/Simulink software allows the highlighting performance of the control strategy adopted.
