A method for compensating at least one low-frequency mechanical disturbance oscillation, which is caused in a rotor of an active magnetic bearing by the action of a disturbance force on the rotor is provided. The mechanical disturbance oscillation has a disturbance oscillation frequency below a rotational frequency of the rotor. The method includes the following steps: a) analyzing the low-frequency mechanical disturbance oscillation, b) determining a compensation force for producing in the rotor a mechanical compensation force that counteracts the mechanical disturbance oscillation, and c) applying the compensation force to the rotor, wherein steps a), b), and c) are performed by means of at least one compensation control circuit of the active magnetic bearing that is decoupled from a magnetic-bearing control circuit for controlling the active magnetic bearing. The invention further relates to a corresponding active magnetic bearing.
