BARRON, M. A.  y  GONZALEZ, J.. An implicit controller for the steel level regulation in a vacuum-based continuous casting process. J. appl. res. technol [online]. 2004, vol.2, n.2, pp.161-169. ISSN 2448-6736.

A nonlinear mathematical model of a vacuum-based continuous casting process and an implicit nonlinear controller are developed. The aim of the controller is the regulation of the mold and tundish molten steel levels. In the proposed approach, the output error is designed to be asymptotically stable, and the current values of the control inputs are numerically determined using the Newton-Rapson iterative procedure. The dynamic performance of the closed-loop system is analyzed using computer simulations.

Palabras llave : Discrete controller; Implicit control; Level control.
