1. A system comprising:
an insulin infusion pump configured to deliver insulin to a patient;
a glucose sensor configured to obtain observations of glucose concentration of the patient; and
a controller configured to:
predict, using an observed current glucose concentration of the patient from the glucose sensor, a respective duration of time for the glucose concentration of the patient to reach each target glucose concentration level of a plurality of target glucose concentration levels;
identify which target glucose concentration level of the plurality of target glucose concentration levels is predicted to be reached first in time;
compare the predicted duration of time for the identified target glucose concentration level against a plurality of threshold time periods corresponding to a plurality of time-to-target checkpoints of the identified target glucose concentration level, to determine an operation of the insulin infusion pump based on the predicted duration of time for the identified target glucose concentration level and the plurality of time-to-target checkpoints; and
generate one or more insulin pump commands to control the determined operation of the insulin infusion pump.
