Robustná stabilita vzduchového tunelu
Robustná stabilita vzduchového tunelu
Práca sa zaoberá spracovaním parametru RSSI reprezentujúceho veľkosť prijímanej výkonovej úrovne rádiového signálu štandardu IEEE 802.15.4 v ISM pásme 2,4GHz. Vzorky signálu sú spracované pomocou aproximačných metód. Na základe RSSI sa ďalej odhaduje vzdialenosť pomocou logaritmického útlmového modelu prostredia (LNSM). Práca sa zaoberá experimentálnym algoritmom pre implementovanie dynamickej kalibrácie jednotlivých koefcientov nutných pre výpočet samotnej vzdialenosti. Je prevedený návrh, spracovanie a overenie tohoto systému v praxi.
Text deals briefly with robust stability which is one of the characteristics of a robust system. This attribute is described in the text; there are investigations carried out of robust stability by complex characteristics on taken models (continuous and discrete) and also on continuous and discrete feedback loop. These results are compared with the results of the physical model.
