Usporedba modela optičkog enkodera s industrijskim enkoderom

First step in this project was designing the model of optical encoder. There where various problems that needed to be solved. Some of them are: signal waveforms from the encoder, mounting the encoder nearby the motor, recording the encoder signals etc. With a fully functional encoder, it was possible to do a comparison with an industrial resolver. The easiest way to do the comparison with an industrial resolver was to simultaneously recording signals from the resolver and the encoder. The signals were recorded using LabView and were saved in a .tdms file. The next step was to process the signals from the resolver using MATLAB. A phase difference was detected by displaying both the resolver and optical encoder position signal of the rotor on the same graph. At lower speeds the phase shift is minimal, but at higher speed the difference is significant.
