Abstract:
1. A turbomachine ( 100 ) comprising: a chamber ( an impeller ( equipments ( a processor ( characterized in that the reference table and the measured values of the first process quantities represent such a set of data values that the estimate is obtainable on the basis of different sub-sets of the set of data values, and the processor is arranged to give, in the calculation of the estimate, more weight to a first sub-set of the set of data values which has a smaller error estimate than to a second sub-set of the set of data values which has a greater error estimate in order to increase the accuracy of the estimate, the error estimate related to each sub-set being proportional to a scalar product of a vector of squares of sensitivities of the estimate with respect to the data values of that sub-set and a vector of variances of the data values of that sub-set.
