A novel method for extraction of speed from resolver output using neural network in vector control of PMSM

The rotor position is integrant information for vector control drive system of Permanent Magnet Synchronous Motor (PMSM). In this paper, the focus is on the rotor position of PMSM detecting by the resolver sensor. The outstanding features of this sensor are its robust structure and noise insensitivity. To extract speed from the output of resolver we need R/D demodulator circuit. A new Artificial Neural Network (ANN) Algorithm is proposed in this paper in substitution for R/D circuit and implemented in the vector control drive system of PMSM. The proposed scheme has been verified by simulation and experiment using MATLAB/Simulink.
