1. An electronic device comprising:

  • a processor architecture comprising at least one processor device; and

    at least one memory element associated with the processor architecture, the at least one memory element storing processor-executable instructions that, when executed by the processor architecture, perform a method of controlling an insulin infusion device for a user, the method comprising;

    initiating a closed-loop operating mode of the insulin infusion device;

    in response to initiating the closed-loop operating mode, obtaining a most recent sensor glucose value for the user;

    calculating a difference between the most recent sensor glucose value and a target glucose setpoint value;

    when the calculated difference is less than or equal to a minimum threshold value, adjusting a closed-loop insulin infusion rate over time, based on a fixed final target glucose value that is derived from the target glucose setpoint value; and

    when the calculated difference is greater than the minimum threshold value, adjusting the closed-loop insulin infusion rate over time, based on a dynamic final target glucose value that decreases over time toward the target glucose setpoint value.
