Assignee: ROBERT BOSCH GMBH
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. The method as claimed in claim 1, wherein the electric machine includes a fundamental controller (200),
the fundamental controller comprising a fundamental input transformer (210), a fundamental controller (220) and a fundamental output transformer (230),
and the method further comprises the steps of:
ascertaining (402) a machine feedback variable (Iabc), the machine feedback variable comprising an actual variable of the electric machine;
transforming (404) the machine feedback variable (Iabc) by means of the fundamental input transformer (210) to form the feedback variable (Idq) in the field-oriented system;
ascertaining (418) the fundamental control deviation as the difference between the specified fundamental DC reference variable (Idq*) and the filtered feedback variable without a harmonic component (IdqFunda) in the field-oriented system;
ascertaining (419) a fundamental DC manipulated variable by means of the fundamental controller (220) as a function of the fundamental control deviation;
back-transforming (470) the fundamental DC manipulated variable by means of the fundamental output transformer (230) to form a machine manipulated variable (Uabc*), and
energizing (480) at least one winding of the electric machine (190) as a function of the machine manipulated variable (Uabc*).
