In this article, an adaptive observer is designed for patients with Type 1 DiabetesMellitus.The adaptive observer, synthesized using the so-called Bergman’sMinimal Model, simultaneously estimates the states and the parameter correspondingto the insulin-independent glucose disappearance rate. The adaptiveobserver dealswith parameter uncertainties,whereas the food intake is regardedas an external disturbance. The adaptive observer relies on intravenous glucosemeasurements. The state estimation error converges to a neighborhood of theorigin despite the effects of the external disturbances and uncertainties, whilethe parameter estimation error converges in a fixed time to a neighborhood of theorigin. The adaptive observer synthesis is given by a constructive method basedon linear matrix inequalities. Simulation results show the feasibility of the proposedscheme. Moreover, the approach is validated in UVA/Padova metabolicsimulator for ten in silico adult patients.< Réduire
