Summary:The paper discusses the results of modeling and testing the prototype of an active vibration control of sliding bearings with the use of piezoactuators. The main goal of the active vibration control is to prevent instability due to the oil film and to extend the operating speed range of sliding bearings. The paper focuses on the analysis of the effect of the feedback controller gain on the operating range of the sliding bearings. This gain can be either a constant or a time varying parameter according to a periodic function.
