Popis: The problem of rotor machines modification requires development of new approaches to the design of specific nodes. As bearings are considered the most important elements of rotor machines, such approaches can imply the application of active control. In the present paper using the example of fluid-film bearings the approach is considered to enchancing energy efficiency of rotor machines by means of generating optimal trajectories. Means are shown to analyze the dynamics of a rotor system and types of the obtained trajectories. The paper also covers the approach to setting the criteria of energy efficiency of rotor’s trajectories. After the optimal trajectory is obtained, active bearings are proved feasible to control the displacement of a rotor by generating a force to match the actual trajectory to the calculated one, and by this to decrease the energy loss.
