The machine is supplied by a 7-leg voltage source inverter (VSI) fed by a DC-bus voltage. In control, current responses are expected to properly track their references. However, several unwanted harmonics of the non-sinusoidal back electromotive force (back-EMF) and the inverter nonlinearity generate unwanted harmonic components in d-q currents. These current harmonics cannot be nullified by controllers such as conventional proportional-integral (PI) controllers. Consequently, the current responses cannot track their references. In this study, a combination of conventional PI controllers and simple adaptive linear neurons (ADALINEs) is proposed to eliminate these current harmonics, improving current control quality of the drive. The effectiveness of the proposed control structure is verified by experimental results.

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.
