Control of a controlled variable of a conditioning unit of a reactant of a fuel cell with determination of an actual value of the controlled variable

摘要

In order to determine at least one actual value of a controlled variable of a reactant of a fuel cell for a control with the smallest possible measurement error, it is provided that a model value of the controlled variable (RGn) is calculated with a model of the conditioning unit (3) with a sensor model (Sn) for the Measuring sensor (Sn) is a model value of the actual value of the controlled variable (RGnm) is calculated from the actual value of the controlled variable (RGnist) measured with the measuring sensor (Sn) and the model value of the actual value of the controlled variable (RGnm) calculated with the sensor model (Sn) (RGcorr) is calculated for the controlled variable (RGn) and the actual value of the at least one controlled variable (RGnist) is calculated as the sum of the correction value (RGcorr) and the model value of the controlled variable (RGn) calculated with the model of the conditioning unit (3) this actual value of the controlled variable (RGnist) also in the sensor model (Sn) for calculating the model value of the actual value of the controlled variable (RGnm) ve is used.
