Claim 0:
1. An artificial pancreas, comprising:
a glucose sensor configured to output glucose data related to a concentration of glucose in the bloodstream of a subject;
an insulin pump;
a memory containing machine readable medium comprising machine executable code having stored thereon instructions for performing a method of delivering insulin; and
a control system coupled to the memory comprising one or more processors, the control system configured to execute the machine executable code to cause the processor to:
store, in the memory, a control action for determining an amount of insulin to inject;
receive, from the glucose sensor, a set of glucose data;
process the set of glucose data to determine whether an update event is triggered;
update the control action to determine a first insulin dose value if the update event has been triggered;
determine a second insulin dose value if the update event has not been triggered, wherein the determination of the second value uses less power than the updating of the control action; and
send a command to the insulin pump to deliver an amount of insulin based on either the first insulin dose value determined by the updated control action or the second insulin dose value.
