Abstract
Two identification methods of linear systems are discussed which explicitly make use of digital filters,
For the realization of these methods, two types of filter-banks and derivative filters of a certain order are used. A method is proposed by which these filters are designed as finite duration impulse response digital filters.
Also some numerical examples of the filters designed by this method are presented with the figures of their frequency responses.
As examples of identification using the proposed methods, two different results are given, One is the frequency response estimation of first and second order lag using signals with special spectra. The other is the parameter estimation of a turbine-generator system installed in some actual thermal power plant (156MW) using data observed under the condition of “on operation”.
