Method and device for stabilising an electric current using a field-oriented control system

摘要

The method involves determining a time profile of oscillation of the rectified electrical voltage (U1) by a measuring device (44), based on field-oriented control of torque setting, thrust force component and perpendicular component of a q-defining stator of an electric machine (18). A set point gradient is regulated for the d-component of the stator current, as a function of the detected vibration of a controller. A control unit (42) is adapted to damp the vibration. The control unit is adjusted by the controller. An independent claim is included for a circuit device.
