Dieses Buch befasst sich hauptsächlich mit der Analyse und Erforschung der konzentrierten Schwingungen, die durch hochfrequente Oberschwingungen der bestehenden DTP-PMSM in einem engen Spreizspektrum angeregt werden. Zunächst wird ein mathematisches Modell der Dual-Drei-Phasen-PMSM erstellt und der maximale Vier-Vektor-SVPWM-Algorithmus eingeführt. Auf dieser Grundlage wird eine mehrfache zufällige SVPWM-Technologie vorgeschlagen, um die Unzulänglichkeiten der traditionellen SVPWM-Methode mit variabler Verzögerung zu beheben. Dann wird ein dual-zentralisierter SVPWM-Algorithmus vorgeschlagen, der die PWM-Oberwellen bei ungeraden Mehrfachträgerfrequenzen eliminiert. Für die asymmetrische PWM-Wellenform wird eine dual-zentralisierte SVPWM auf der Basis eines Dreiecksträgers vorgeschlagen, die die Implementierungsschwierigkeiten reduziert. Darüber hinaus wird in Kombination mit der Methode der variablen Verzögerung der Einfluss der Methode der variablen Trägerfrequenz auf das niederfrequente Band reduziert. Schlie lich werden Simulations- und experimentelle Studien unter den Aspekten der Analyse der Hochfrequenzharmonischen, des Schwingungsbeschleunigungstests, des Spektrumsausbreitungsfaktors und der Leistungsanalyse im Niederfrequenzbereich durchgeführt, um die Wirksamkeit der vorgeschlagenen Regelstrategie zu überprüfen.
