Mapping error of simplified dynamic models in electrical metrology

The paper presents a theory and ifs practical application ill the process of the determination? of the mapping error of simplified dynamic models. This mapping is expressed by means of the integral-square-error criterion. A special calculation algorithm shelving how to compute the maximum value of this criterion is discussed and presented in detail. The paper shows also the method of a synthesis of a special class of simplified models which, in the initial time interval, map the models of the higher order with a very snail error. The particular transformations, presented in the matrix notation, are defined in this paper for this method The theory presented in the paper is illustrated with a numerical example.
