“…Although the majority of HFI methods process the derived currents to extract rotor position information, it is feasible to use zero-sequence carrier voltage instead [16]. The carrier signal at the switching frequency can also be used to provide rotor position information; compared to the previous HFI methods, this method provides an alleviated acoustic noise and vibration level due to the high frequency of carrier signal [17], [18]. In addition to the current or EMF, the vibration on the surface of stator can also be processed to obtain the magnet polarity for a given PMSM [19].…”

In this paper, a novel sensorless control for Permanent Magnet Synchronous Machine (PMSM) using its radiated acoustic noise is proposed in which a highfrequency voltage signal is superimposed upon the fundamental excitation and the machine response to such excitation is studied. Firstly, the analytical equations describing the field formation within the airgap leading to the generation of radial forces and acoustic noise are extensively investigated. In the next step, resulting harmonics in the acoustic noise waveform caused by the injected signals are predicted. Then it is experimentally verified that, depending on the machine structure, there will be some distinctive sidebands around the injected frequency directly related to the fundamental synchronous frequency. Acoustic noise waveform is highly distorted and sensitive to the environment, so a proposed 4-stage signal processing algorithm containing two self-adaptive Band-pass Filters (BPF) are used to safeguard the signal against unwanted distortions and flawlessly extract the rotor position information. Robustness and effectivity of this method is verified experimentally in various operating conditions.

“…Given the variation of motor parameters along with the change in the operating environment, the precise calculation or identification of motor parameters is the primary problem and limitation in realizing higher driving performance [6][7][8][9] . The rotor position estimation is another essential part that needs to be designed optimally for the sensorless controlled SynRMs, which can further maximize the advantage of low cost and promote the application of SynRMs for cost-sensitive applications [10][11][12][13][14][15][16][17][18][19][20][21] . In addition, the precise knowledge of motor parameters is favorable for the improvement of sensorless control performance of SynRMs.…”

Synchronous reluctance machines (SynRMs) have drawn increasing attention in recent years owing to their advantages such as low cost, simple structure, ease of manufacture, and high robustness. The main obstacle to the promotion of SynRMs is severe parameter nonlinearity, which deteriorates drive performance. Sensorless control methods for SynRMs are critical technologies that can broaden the industrial applications of SynRMs. Various methods of parameter identification and sensorless control strategies are reviewed and discussed, including self-commissioning, which is analyzed in detail. Furthermore, sensorless control strategies that can improve the industrial application of SynRMs are described. Finally, future research trends concerning SynRMs are analyzed and discussed.

“…Dies stellt einen Kompromiss zwischen der kostengünstigen SynRM ohne Permanentmagnete und der hoch effizienten PMSM dar. Ein weiterer wesentlicher Aspekt bei SynRM ist der mögliche lagegeberlose Betrieb [5,6,13]. Dieser reduziert zum einen die Anschaffungs-und Wartungskosten, zum anderen wird die Ausfallsicherheit erhöht.…”

In dieser Arbeit wird die Problematik der unerwünschten Harmonischen im Strangstrom sowie in der Strangspannung behandelt. Diese Harmonischen treten besonders im Fall der Synchron-Reluktanzmaschine mit Einzelpolen auf. Es wird das konventionelle mathematische Modell erweitert, um die Erzeugung der Harmonischen erklären und beschreiben zu können. Auf Grundlage des modifizierten mathematischen Modells wird eine Regler-Struktur vorgestellt, welche die unerwünschten Harmonischen im Strom bzw. in der Spannung erheblich reduziert. Dieses Regelkonzept benötigt lediglich die Frequenz der Harmonischen, wodurch ein universeller und robuster Einsatz möglich wird. Schlussendlich werden die vorgestellten Regelkonzepte anhand von Experimenten an einem Prototyp verifiziert. Schlüsselwörter: Synchronmaschine; Reluktanzmaschine; Harmonische; elektrische Antriebe; Echtzeit-Kompensation Analysing reduction possibilities of harmonic disturbances in synchronous reluctance machine drives. In this paper a current and voltage ripple reduction method is evaluated. These harmonic disturbances occur especially in synchronous reluctance machines with salient pole configuration. The fundamental wave model has to be enhanced to handle these unwanted harmonic effects. With this extended model a current and voltage ripple suppression method was developed, which only needs the frequency of the harmonic disturbance. Finally, the introduced control algorithms were verified on the prototype.
