Abstract

A method for model-based open-loop and closed-loop control of an internal combustion engine, in which method injection system setpoint values for activating the injection system control elements are calculated dependent on a setpoint torque by a combustion model, and gas path setpoint values for activating the gas path control elements are calculated by a gas path model. The combustion model is adapted during ongoing operation of the internal combustion engine. A quality measure is calculated by an optimizer dependent on the injection system setpoint values and the gas path setpoint values, the quality measure is minimized by the optimizer by varying the injection system setpoint values and gas path setpoint values within a prediction horizon. The injection system setpoint values and gas path setpoint values are set by the optimizer, based on the minimized quality measure, as being definitive for setting of the operating point of the internal combustion engine.
