Claim One:
1. A method to control an infusion pump with a microcontroller to control the pump and receive data from at least one glucose sensor, the method comprising: measuring glucose level in the subject from the glucose sensor to provide at least one glucose measurement in each time interval in a series of discrete time intervals; determining whether the glucose sensor has been replaced by a new glucose sensor within a predetermined time interval; if the determining step is true, setting a tuning factor (R) for a model predictive controller in the microcontroller as a conservative setting otherwise if the determining step is false, maintaining a current tuning factor (R) for the controller; calculating an insulin amount for delivery by the microcontroller based on a model predictive controller that utilizes the tuning factor (R) so as to provide a calculated insulin amount to be delivered to the subject for one or more of the discrete time intervals; and delivering via actuation of a pump by the microcontroller of the insulin amount determined from the calculating step.
