Induction motor speed estimation using artificial neural networks
P. Mehrotra, John E. Quaicoe, Ramachandran Venkatesan · 2002
This paper derives two functional relationships between the stator quantities and speed from the induction motor dynamic equations. As singularities are present in these relationships, direct estimation of speed using artificial neural networks (ANNs) with these stator inputs is not possible. The paper proposes a scheme which employs two ANNs for this purpose. The outputs of the two ANNs are further processed to obtain the induction motor speed. The speed recovery scheme does not depend upon any particular control strategy.
