Abstract

This paper present the review on sensor less control of Doubly fed induction machines using various methods like Model Reference Adaptive Scheme (MRAS), Field oriented control (FOC), Fuzzy logic, Artificial Neural Network(ANN) etc. and the whole analysis reveals the better dynamic performance of Sensor less speed estimation over conventional method of speed and current measurement of DFIM which reduces the error in the measurement of parameters, better noise immune, more efficient and reliable system.
