Abstract:
A method for regulating a smooth running of a multicylinder internal combustion engine, which comprises:measuring continuously determined state variables of an internal combustion engine having individual cylinders;using the state variables in a model for estimating a characteristic process variable representing a desired value for regulating the internal combustion engine;determining an instantaneous actual value corresponding to the desired value from the state variables, the actual value taking into account a rotational acceleration contribution of each of the individual cylinders;deriving a regulating difference from the desired value and the actual value;transmitting the regulating difference to a controller;correcting with the controller a combustion in the individual cylinders for minimizing the regulating difference; andoutputting an error state if the controller cannot minimize the regulating difference by correcting the combustion in the individual cylinders.
