Abstract: The present paper shows the design of a fault-tolerant control strategy based on
knowledge. This strategy avoids the cavitation of a centrifugal pump in a loop of level
control, using a detection system and fault diagnosis and supervisory control, which are
constructed from a qualitative model, where the prediction of process behavior interacts
with observation itself.

Keywords: Fault-tolerant control, knowledge based system, detection and fault diagnosis
system, supervisory control, cavitation.

de un lazo de control de nivel, utilizando un sistema de detección y diagnóstico de fallos y
un control supervisorio, los cuales se construyen a partir de un modelo cualitativo, donde
la predicción del comportamiento del proceso interactúa con la observación del mismo.
