Research output: Chapter in Book/Report/Conference proceedingConference contribution


In this work the Real Interpolation Method (RIM) for the solution of System Identification problem is proposed. It allow to create the sufficiently cost-effective algorithmic basis and to solve all complex of Identification problems under field conditions immediately: to gain the information about the system, to process it, to form current dynamic characteristics and to compare them with etalon. It is founded on usage of a special case of the Laplace transformation, when the complex variable p = δ + jω is degenerated in real δ. The number of operations is diminish more than 2 times in comparison with the frequency method. Real Interpolation Method is equivalent to the frequency method from positions of noiseproof features. The possibilities of the RIM allow to use it for Identification of linearized continuous and discrete systems, and also for their subsequent tuning.
