H02P 21/13 Arrangements or methods for the control of electric machines by vector control, e.g. by control of field orientation - Observer control, e.g. using Luenberger observers or Kalman filters

H02P 21/05 Arrangements or methods for the control of electric machines by vector control, e.g. by control of field orientation - specially adapted for damping motor oscillations, e.g. for reducing hunting

H02P 21/14 Arrangements or methods for the control of electric machines by vector control, e.g. by control of field orientation - Estimation or adaptation of machine parameters, e.g. rotor time constant, flux, speed, current or voltage

H02P 23/04 Arrangements or methods for the control of ac-motors characterised by a control method other than vector control - specially adapted for damping motor oscillations, e.g. for reducing hunting
