1. A method to control an infusion pump with a model-predictive-controller 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 interval index (“

    k”

    );

    predicting at least one future glucose value based on the glucose measurements made in the measuring step;

    evaluating whether the at least one future glucose value is within a predetermined range of glucose values;

    in the event the at least one future glucose value is not within the range, determining an insulin amount with the model-predictive controller based on a target value otherwise determining an insulin amount with the model-predictive-controller based on the predetermined range; and

    delivering the insulin in the amount determined in the determining step.
