Beschreibung
Zusammenfassung:	A method for estimating a quantity of a system includes the following steps:for each variable of a plurality of variables, obtaining a sequence of successive measurements,determining a sequence of successive values of a stability parameter, the parameter being a weighted sum of rates of variation of the variables,identifying a time interval in which the stability parameter is less than or equal to a predetermined threshold for a duration greater than or equal to a predetermined duration,estimating a sequence of successive estimates of a particular variable, a start time of the sequence being included in the time interval,comparing the sequence of estimates and the sequence of measurements, in order to determine an adjustment parameter, andestimating the physical quantity of the system using the adjustment parameter.
