| Abstract |
The paper analyses a modified version of the model reference adaptive system (MRAS) based speed
estimator, whose outputs of the reference and the adjustable model are rotor flux space vectors. The
estimator is modified in such a way that the variation in the instantaneous level of the main flux
saturation during operation in the field weakening is recognised and properly compensated at all times.
Verification of the proposed scheme is provided by simulation and by experimentation on an indirect
feed-forward rotor flux oriented induction machine for speed references of up to twice the base speed. |
