Speed control of induction motor without rotational transducers

Ben-Brahim, Lazhar; Tadakuma, Susumu; Akdag, Alper ( IEEE , 1999 , Article)

This paper describes a newly developed speed sensorless drive based on neural networks. A backpropagation neural network is used to provide real-time adaptive identification of the motor speed. The estimation objective is ...

Optimization of the skew angle of rotor poles in permanent magnet machines based on the inverse problem method

Alhamadi, M.A.; Demerdash, N.A.O. ( IEEE , 1999 , Article)

This paper presents optimization of the skew angle of rotor magnetic poles in permanent magnet brushless dc machines. The skew angle optimization is achieved using the gradient based inverse problem methodology. The paper ...
