Abstract
The present invention provides control of a synchronous machine with non-sinusoidal current-voltage profiles. The synchronous machine is controlled in a field-oriented coordinate system. In this case, the transformation between field-oriented coordinate system and stator-oriented coordinate system is effected by specific, adapted transformations which take account of the non-sinusoidal signal profiles during the driving of the synchronous machine, such that the latter correspond to current-voltage profiles progressing in a constant fashion in the field-oriented coordinate system. What is achieved thereby is that the non-sinusoidal current-voltage profiles need not be taken into account in any way in the design of the control system in the field-oriented coordinate system.
