Method for regulating an internal combustion engine, computer program and control unit

摘要

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.

1. A method for controlling 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 comprising:
determining, by a control unit including a computer processor, a desired value of a combustion position feature of the combustion process of the engine; determining, by the control unit, a target value of 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 wherein the target value of the manipulated variable is determined as 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; and controlling, by the control unit, the engine operation by actuating at least one physical control component of the engine based on the target value of the manipulated variable.
