    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.

    Abstract: The present invention provides control for synchronous machines in order to achieve an approximately constant torque irrespective of the load angle. The induced voltage of the synchronous machine rotating with a zero-current of the stator is first determined. Starting from the voltage plot of the induced voltage over the load angle, a current plot which achieves a constant torque irrespective of the load angle or any other default settings, can then be calculated. In particular, a non-sinusoidal current plot can also be calculated for non-sinusoidal plots of the induced voltage in the synchronous machine, in order to achieve desired settings that are as constant as possible irrespective of the load angle of the synchronous machine.
