1. A method for controlling a motor, the method comprising:
determining, via a control unit (34), a controlled variable (16) in a control loop (14),
compensating, via the control unit (34) a variation in an operating parameter of the motor, by adjusting (18) the controlled variable (16) by logically combining the controlled variable (16) to an adjustment variable (20) to counteract at least one harmonic oscillation of the operating parameter, wherein a characteristic variable (26) of the harmonic oscillation is determined for setting the adjustment variable (20), wherein the characteristic variable (26) is an amplitude of the harmonic oscillation.
