Speed-Sensorless Vector Control of an Induction Motor Using Neural Network

신경망을 이용한 유도 전동기의 센서리스 속도제어

In this paper, a novel speed estimation method of an induction motor using neural networks(NNs) is presented. The NN speed estimator is trained online by using the error backpropagation algorithm, and the training starts simultaneously with the induction motor working. The neural network based vector controller has the advantage of robustness against machine parameter variation. The simulation results using Matlab/Simulink verify the useful of the proposed method.
