Resumen:
BackgroundControl algorithms for artificial pancreas based on a control oriented model of the blood glucose variation with respect to the subcutaneous injected insulin must be adjusted according to each patient and usually have several parameters that should be identified.MethodThis work presents the preliminary results of a control algorithm for artificial pancreas using the EMC design methodology [1], extracting a linear and time-invariant model of the linear parameter-variant (LPV) model presented in [2], and augmented it by a proper disturbance dynamics designed to handle the uncertainties. This so called embedded model (EM) has only two parameters and no delay, which is a remarkable novelty with respect to previous works, where more complex models have been successfully used in clinical trials.ResultsPreliminary results are satisfactory and were validated using in-silico patient population. The control system works even in the virtual patient excluded in the original LPV model exhibiting good performance (see figure). ConclusionThe EMC controller was able to regulate the blood glucose for all in-silico patients with a unique and novel EM for all of them. This performance is susceptible to be improved in future works since others EM based on the original non-linear dynamics model can be implemented.
