    Abstract: The present invention relates primarily to a method for controlling the rotational rate of a compressor, which controls, in particular, the rotational rate of a rotating compression element of the compressor. The invention furthermore relates to a compressor, e.g. a compressor for generating pressurized air. The compressor is to be operated at a rotational rate, when in operation, with a mean value that is at least as high as a minimum mean value, in order to ensure the functionality of the compressor. According to the method, a temporally variable target rotational rate of the compressor that is necessary for obtaining a temporally variable output performance from a compressor is determined. In accordance with the invention, a lower rotational rate limit is raised if the temporal mean of the variable target rotational rate is lower than the minimal mean value for the rotational rate of the compressor.
