MRAS-Type Speed and Flux Estimator with Additional Adaptation Mechanism for the Induction Motor Drive
Abstract
This paper deals with a novel Model ReferenceAdaptive System (MRAS) estimator of the rotor flux and
speed reconstruction for induction motor drive. The
proposed estimator is based directly on the mathematical
model of the induction motor. In comparison with existing
methods the additional variable is introduced, which has to
reduce partly the estimator sensitivity to the rotor time
constant changes. Chosen simulation tests of the proposed
solution are presented.
