Current Harmonic Eliminations for Seven-Phase Non-sinusoidal PMSM Drives applying Artificial Neurons
Ouvrage scientifique
Résumé
This study is to deal with unwanted current harmonics in rotating (d-q) frames of a 7-phase non-sinusoidal permanent magnet synchronous machine (PMSM) in a wye-connected winding topology. The machine is supplied by a 7-leg volt-age source inverter (VSI). In control, currents in d-q frames are expected to properly track their time-constant references. However, unwanted harmonics of the non-sinusoidal back electromotive force (back-EMF) and the inverter non-linearity generate unwanted current harmonics in d-q frames. These current harmonics cannot be nullified by conventional proportional-integral (PI) con-trollers. In this study, a combination of PI controllers and adaptive linear neu-rons (ADALINEs) are proposed to eliminate these current harmonics after ana-lyzing their origins. The effectiveness of the proposed control structure is veri-fied by experimental results.
