Abstract:
1. A method for controlling an electrical consumer of an aircraft, comprising: determining a rotational frequency for an electric motor; determining oscillations in an input current of an inverter based on the determined rotational frequency for the motor, the oscillations produced by the inverter as the inverter produces a supply voltage for the electric motor; changing the rotational frequency of the electric motor based on the determined oscillations in the input current of the inverter such that a frequency of the oscillations in the input current of the inverter exceeds a predefined threshold determining a rotational frequency range in which the rotational frequency leads to oscillations in the input current of the inverter, whereby the frequency of the oscillations is below the threshold, if it has been established that the rotational frequency leads to oscillations in the input current of the inverter, whereby the frequency of the oscillations is below the predefined threshold; and changing the rotational frequency to an end of the rotational frequency range.
