The approach to building the algorithm for controlling rotor motion in a hybrid mechatronic bearing

The paper describes the approach to building the algorithm for controlling the rotor motion in a hybrid mechatronic bearing. Such bearings include a rolling bearing, a gas foil bearing, an electromagnetic and a piezo actuator. Fuzzy logic techniques are used in the proposed algorithm. Its main aim is to minimize the deviation of the rotor position in the bearing from the equilibrium position. It results in reducing the vibrational activity of the rotor-bearing system and reducing the friction losses
