Abstract

Se describe un sistema de fundición de doble rodillo que incluye un par de rodillos de fundición contrarrotativos que tienen una separación ajustable entre los mismos, un controlador de rodillo de fundición se configura para ajustar la separación entre los rodillos de fundición en respuesta a las señales de control; un sensor de banda fundida mide un parámetro de la banda fundida y genera señales de medición de banda; y un controlador de control de aprendizaje iterativo (ILC - iterative learning control) recibe las señales de medición de banda y proporciona señales de control al controlador de rodillos de fundición. El controlador de ILC incluye un algoritmo de detección de fallas que recibe las señales de control y las señales de medición de banda y genera una señal de detección de fallas que indica cuándo se detecta una condición de falla y un algoritmo de control de aprendizaje iterativo para generar las señales de control. El algoritmo de detección de fallas indica una condición de falla cuando detecta que la señal de control supera un umbral de saturación de control superior o el controlador de ILC que opera un estado que no se garantiza como estable.
