Classification: CPC H | IPC H

Claim 2:
3. The method as claimed in claim 1, wherein the electric machine includes a first filter (140) and a filter input transformer (112),
and the method further comprises the steps of:
filtering (411) a specifiable fundamental DC reference variable (Idq*) by means of the first filter (140);
ascertaining (412) the filtered feedback variable without a harmonic component (IdqWoFunda) as the difference between the feedback variable (Idq) and the filtered fundamental DC reference variable (Idq*); and
transforming (413) the filtered feedback variable without a fundamental component (IdqWoFunda) by means of the filter input transformer (112) to form a DC feedback variable (IHrmc) in a harmonic-oriented system,
wherein the DC feedback variable (IHrmc) is specified as the filter specification variable (FV).
