Dynamic identification of electric motor parameters on the basis of QR-decomposition technique

Dynamic identification of DC motor on the basis of QR-decomposition technique is given in this paper. Authors propose to identify DC motor parameter using step-by-step method of rotor´s parameters definition. The first step is definition of main poles magnetic flux and active resistance of exciting circuit Active resistance, rotary rotations are defined on the second step. Appropriate equations of transforming are given in the article. Identification results using this technique are presented on the graphs. Also the results of simulation are shown in the paper.
