CORRECTION OF DYNAMIC ERROR BY THE ""BLIND” METHOD. A DIFFERENTIAL ALGORITHM SIMULATION STUDY

Jacek Nalepa

Abstract

The „blind” method of correction algorithm uses the results of two parallel measurement channels and consists of two stages. The first stage is identification of the dynamic properties of the measurement channels, the second one is the correction itself. A differential algorithm of identification based on minimisation of the difference between the results of both measurement channels connected with correctors. The paper presents the results of the simulation study on the differential algorithm of the correction of the dynamic error for measurement channels modelled as first- and second-order system. A simulation study similar to that presented in the paper, can be an effective instrument to determine conditions for the practical applicability of the dynamic error correction by the „blind” method for a particular measurement channels.
