| Abstract |
The paper presents the combination of a lowspeed
model (“INFORM method”) and a specially adapted
high speed model (“Voltage model or EMF model”) for
covering the full speed range of sensorless permanent
magnet (PM-) synchronous motor drives. Both models
generate “measuring information” for a linear observer,
modelling the mechanical structure of the motor. A special
feedback loop is introcuded, coupling back the observer
information to the integrating voltage model. Thus, a stable
operation with high robustness against parameter
uncertainties and low frequency disturbances is achieved. |
