dc.description.abstractPossibilities of active lateral vibration reduction of a symmetric, rigid rotor supported by journal bearings are given. They were obtained by computational modelling. Efficiency of the feedback P and PD controllers in the stable revolution interval was examined. The linearized rotor system model was used. The results of the theoretical analysis are assigned for a testing stand where the bearing bush motions are deactivated by piezoelectric actuators connected to the controllers.en
dc.description.abstract-enOvaj rad prikazuje mogušnosti aktivnog prigušivanja lateralnih vibracija simetričnog, krutog rotora sa kliznim ležajevima korištenjem računalnog modeliranja. Istražena je učinkovitost povratne sprege P I PD kontrolnih sklopova u stabilnom okretnom interval. Korišten je linearizirani model rotorskog sustava. Rezultati teoretske analize bit će korišteni za rad na ispitnom stolu, gdje se pokreti ležajnih blazinica kontroliraju piezoelektričnim pokretačima spojenim sa upravljačkim sklopovima.en
