Abstract

The invention relates to a method (400) for regulating an electric machine (190) comprising a harmonic regulator (100), wherein the harmonic regulator comprises an input transformer (110), a regulator (120), and an output transformer (130). The method has the steps of: ascertaining (410) a feedback variable (Idq); transforming (420) the feedback variable (Idq); ascertaining (430) a regulating deviation; ascertaining (440) an equalization variable (UHrmc*); back-transforming (450) the equalization variable (UHrmc*); and energizing (480) at least one winding of the electric machine (190) on the basis of the actuating variable (UdqHrmc*).
