AUTOMATIC CONTROL SYSTEM OF THE AXIAL ELECTROMAGNETIC ROTOR BEARING WITH ADAPTATION TO CHANGES IN STATIC FORCE Russian patent published in 2022 - IPC H02K7/09 H02P6/16 G05B11/36 F16C32/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. The automatic control system of the axial electromagnetic rotor bearing includes an axial channel containing a rotor position sensor (1), a shaft position setting unit (2), a comparison element (3), a vibration signal processing unit (4), a proportional controller (5), an integral controller (6), a differential controller (7), a proportionally-differential controller (8), a comparison element (9), a proportional current controller (10), a current sensor (11), a power converter (12), two electromagnets (13) and (14), an axial force calculation unit (15), a displacement calculation unit (16), an additional comparison element (17). The input of the axial force calculation unit (15) is connected to the output of the integral controller (6), the input of the additional comparison element (17) is connected to the input of the comparison element (3) and the output of the setting unit (2). The displacement calculation unit (16) is located between the output of the axial force calculation unit (15) and the input of the additional comparison element (17).

EFFECT: increase in resistance to high static loads, an increase in performance and an expansion of the range of compensated static forces of the automatic control system of the axial electromagnetic rotor bearing.
