Abstract

An engine control unit having a one-time integration of a model predictive control template via a potentially long software process. Changes to the control structure may subsequently be made via a calibration dataset connected to the engine control unit without incurring the potentially long and laborious software process of implementing the template of other approaches in the related art.
