Abstract (en)
[origin: WO2021151950A1] The invention relates to a method (100) for controlling an electric machine (204) with a harmonics controller (200), which comprises an input stage (210), a controller (220) and an output stage (230), comprising the following steps: determining (110) at least two measurement variables (id, iq); determining (120) cosine measurement portions and sine measurement portions (idcos_m, idsin_m, iqcos_m, iqsin_m); determining (130) the cosine control variables and sine control variables (idcos_s, idsin_s, iqcos_s, iqsin_s); determining (140) at least two control variables (ud, uq); and actuating the electric machine (204) according to the determined control variables (ud, uq).
