ANALYSIS OF THE ADJUSTMENT FOR THE STABILIZING PARAMETERS FOR COUPLING PARTS OF THE DECOMPOSED RADIO SYSTEM USING THE SCHUR'S COMPLEMENT
The article continues the cycle of the author's works on the subject of HIL-simulation. The article proposes an algorithm for the decomposition of any radio system and the subsequent coupling of its parts by adjusting only one of the two stabilizing parameters of the coupling scheme. In addition, the possibility of using a coupling scheme as a matching device between fragments of the system through the aspect of system stability was analyzed. All this makes it possible to significantly reduce the amount of debugging work performed in HIL-simulation of radio systems, both in the field of research of elementary systems and in working out options for creating complex multisystems. As a proof of the correctness of the proposed method, an analytical calculation was performed, in general, showing the possibility of adjusting only one stabilizing parameter in the coupling scheme of a decomposed system, while convergence of the parameters of the divided system to the parameters of the original system can be achieved in several iterations. In some cases, this convergence can be achieved in one iteration. In the conclusion of the article, the calculation was performed using a numerical example for practical confirmation of the proposed method. For clarity and correct understanding of the described actions, illustrations are given of both the operations performed and the results of the calculations.
