Abstract
A method for regulating an internal combustion engine that is operable, at least in a part-load range, in an operating mode with auto-ignition and a combustion process of which is influenced by a manipulated variable, the method includes the steps of determining a desired value of a combustion position feature of the combustion process; determining the manipulated variable by predictive closed-loop control based on a modeling of the combustion position feature as a function of the manipulated variable in the combustion process; and determining, as the manipulated variable, a value at which the difference between the desired value of the combustion position feature and a model-based predicted combustion position feature is minimized.
