W niniejszej książce przeprowadzono glównie analizę i badania skoncentrowanych drgań wzbudzanych przez harmoniczne o wysokiej częstotliwości istniejącego DTP-PMSM w wąskim zakresie widma rozproszonego. Po pierwsze, opracowano model matematyczny dwu-trójfazowego silnika PMSM i wprowadzono algorytm SVPWM z maksymalnym czterowektorem. Na tej podstawie, w celu wyeliminowania wad tradycyjnej metody SVPWM o zmiennym opóźnieniu, zaproponowano technologię wielokrotnego losowego SVPWM. Następnie przedstawiono podwójnie scentralizowany algorytm SVPWM, który eliminuje harmoniczne PWM przy nieparzystych częstotliwościach nośnych. W przypadku asymetrycznego ksztaltu fali PWM zaproponowano podwójnie scentralizowany SVPWM oparty na trójkątnej nośnej, co zmniejsza trudnośc implementacji. Ponadto, w polączeniu z metodą zmiennego opóźnienia, wplyw metody zmiennej częstotliwości nośnej na pasmo niskiej częstotliwości jest zmniejszony. Na koniec przeprowadzono badania symulacyjne i eksperymentalne pod kątem analizy harmonicznych wysokiej częstotliwości, testu przyspieszenia drgań, wspólczynnika rozrzutu widma i analizy wydajności niskiej częstotliwości w celu zweryfikowania skuteczności proponowanej strategii sterowania.
