Resumen:
The development of an artificial pancreas for the treatment of insu-lin-dependent diabetes is a big challenge for control theory. Many closed-loop algorithms have been widely evaluated for their ability to recreate, as closely as possible, glucose and insulin profiles observed in healthy individuals. Neverthe-less, an artificial pancreas system also involves a critical necessity for supervi-sion of the control loop functioning and the early detection of anomalies as well as performance deterioration. This work presents a performance monitoring ap-proach using Bayesian surprise to fast detect functional degradation and guaran-tee adequate control of blood glucose levels. Bayesian surprise is significantly affected by any deviation from desired operation in a controlled system, which allows its use for continuous glucose monitoring.
