Abstract

In this paper, model reference adaptive control (MRAC) schemes are developed for discrete-time plants in the presence of sensor uncertainties. Two adaptive schemes are proposed for both known and unknown plant dynamics to account for parametrizable sensor uncertainties when reliable output measurements are not available for feedback. As an illustrative example, a simulation study is carried out for adaptive control of an artificial pancreas dynamic model with glucose sensor uncertainties, for desired blood glucose regulation.
