Method for model-based control and regulation of an internal combustion engine

摘要

Proposed is a method for model-based control of an internal combustion engine (1) in which, depending on a desired torque (M (SOLL)) via a combustion model (20) injection system setpoints for controlling the injection system actuators and a gas path model (22) gas path Setpoints for driving the gas path actuators are calculated, in which the combustion model (20) during operation of the internal combustion engine (1) is adapted, by an optimizer (23) a quality measure in dependence of the injection system setpoints and the gas path setpoints the optimizer (23) minimizes the measure of goodness by varying the injection system setpoints and gas path setpoints within a prediction horizon, and using the optimizer (23) to set the injection system setpoints and gas path setpoints as critical to setting the Operating point of the internal combustion engine (1) are set.
