Abstract
The invention relates to field-oriented current regulation for a permanent magnet synchronous machine () in which setpoint values for the components Id and Iq of the current in the Park coordinate system are limited according to an operating point, wherein a manipulated variable Uqr or Udr of a respective current regulator () is prioritized for the Iq or Id component, whose corresponding component of the induced voltage Uq, Uddrives the current most strongly away from the short-circuit point. The sign of a rotational speed Ω of a rotor in the synchronous machine () and the signs of Uqr and Udr in particular can be used for the decision regarding the prioritization of Uqr and Udr.
