Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The general principles to construct a linear space of models under identification of dynamic systems based on the input and output vector-functions Kazakov O.A. The structure identification method for linear dynamic models of the alternating current electromagnetic systems is suggested in the article. General principles of models’ linear space construction are considered. With the help of the M linear operators system (Sm) and using the power sequence of differentiation operator two linearly independent vector-function systems are con-structed (Krylov’s differential basis), which are generated by the smooth M-dimensional vector-functions approximating an input and an output signals. The linear transformation equations for Krylov’s differential basis are the basis for a class (linear space) of equivalent homogeneous linear differential model. Контактный телефон 8-499-972-95-20.
