The new, original control method of the vibratory conveyor operating on the Frahm's dynamic eliminator basis, is presented in the paper. The proposed method is based on the application of the control of the feed-forward controler, together with the events detection based on the generalised likelihood ratio (GLR) algorithm. Such approach leads to the controller intervention only when it is justified by the current process situation, (e.g. in case of an essential change of the feed mass) to enable the stable machine operations and to limit transient states. The results are presented in a form of numerical simulations.

W artykule przedstawiono oryginalny sposób sterowania przenośnikiem wibracyjnym, działającym w oparciu o dynamiczną eliminację drgań na zasadzie eliminatora Frahma. Zaproponowana metoda polega na zastosowaniu sterowania typu feed-forward wraz z detekcją zdarzeń opartą na algorytmie sum kumulacyjnych (GLR). Podejście takie prowadzi do interwencji regulatora tylko wtedy gdy jest to uzasadnione bieżącą sytuacją procesową, np. w przypadku istotnej zmiany masy nadawy, co zapewnia stabilną pracę maszyny i ogranicza stany przejściowe. Wyniki przedstawiono w postaci symulacji numerycznych.
