Abstract

It is described a control arrangement (260, 360) for controlling plural stator currents (Ia, Ib, Ic) of plural stator windings (113, 115, 117) of an electrical machine (111, 211), comprising: a fundamental current controller (371); at least one harmonic voltage controller (373a, 373b) configured to receive as inputs a winding voltage signal (391) related to voltages at the plural stator windings, a reference winding voltage signal (392) related to reference voltages at the plural stator windings and an electrical angle (Θe) of the electrical machine, wherein the harmonic voltage controller is configured to output an reference harmonic current command (393, Idnref); at least one harmonic voltage calculation module (369a, 369b) configured to receive the reference harmonic current command (393a, 393b) and to output a harmonic voltage command (Vdnh, Vqnh) based on the reference harmonic current command; and a summation system to obtain a summed voltage command (398, Vd, Vq) based on which the converter (119, 219) is controllable.
