Claim 0:
1. A system to control glucose in a patient, the system comprising:
a medication delivery device configured to deliver a medication dose to the patient; and
a controller operably coupled to the medication delivery device and including control logic operative to:
execute a multi-model predictive controller algorithm at least in part by executing a plurality of models each comprising a plurality of model parameters having a set of values, wherein executing the plurality of models includes propagating multiple state vectors,
select one of the plurality of executed models based at least in part on differences between glucose values of the propagated state vectors and previously measured glucose values,
calculate a basal deviation using the selected model, wherein the basal deviation is a dosage amount above or below a predefined basal profile, and
determine a first medication dose based at least in part on the calculated basal deviation and the predefined basal profile.
