“…Normalean, sentsoreak erabiltzen dira posizio hori zehazteko, hala nola posizio-kodetzaile (encoder, ingelesez) absolutu edo erlatiboak eta kodetzaile angeluar analogikoak (resolver, ingelesez), besteak beste. Sentsore horien erabilerak makinaren kostua eta tamaina handitzen dute [32,33]. Horrez gain, momentu elektromagnetikoaren kontrola ezingo litzateke gauzatu hutsegite bat gertatzen bada posizio-sentsorean.…”

Laburpena:Ibilgailu elektriko eta hibridoetako propultsio-sistemetan erabiltzen diren motor elektrikoen artearen egoera aztertzen du artikulu honek. Horrez gain, makina horiek kontrolatzeko ohikoak diren FOC (Field Oriented Control) eta DTC (Direct Torque Control) kontrol-egiturak azaltzen eta konparatzen dira, eta baita motorraren posizio eta abiadura mekanikoa neurtzen duen sentsorerik gabeko kontrola (sensorless, ingelesez) ere: behatzaileetan oinarritutako estimadoreak, abiadura moderatu eta altuetarako baliagarriak direnak, eta salientzia magnetikoan oinarritutako metodoak, abiadura baxu edota ibilgailua geldi dagoenean ezartzen direnak. Amaitzeko, teknologiak etorkizunean izan ditzakeen erronkak eta joerak azaltzen dira. Hitz-gakoak:Ibilgailu elektrikoa, motor elektrikoak, sentsorerik gabeko kontrola. Abstract:This article provides a state of the art of the electric machine technology used in Electric and Hybrid Electric Vehicle applications. Most common FOC (Field Oriented Control) and the DTC (Direct Torque Control) strategies are explained and compared. Position and speed sensorless control strategies are also detailed: observerbased estimators, suitable for medium/high speed ranges and magnetic saliency based methods, applicable for low speeds and standstill operation. Finally, challenges and future trends of this technology are provided.

“…Furthermore, Maslen, Montie, and Iwasaki [6] argue that they are not able to achieve significant improvements in the output sensitivity function since an output disturbance near the frequency of the periodic perturbation γ sin (ωt) would destroy the ability of the controller to accurately determine the air gap. A similar technique has been utilized to determine rotor position in reluctance motors [7], [4], but as with self-sensing magnetic bearings a complete analysis of the robustness implications is presently lacking in the literature.…”

Abstract-In "Magnetic Bearing Measurement Configurations and Associated Robustness and Performance Limitations", Thibeault and Smith demonstrate that self-sensing magnetic bearings are impractical due to fundamental limitations in the achievable closed-loop robustness. Due to experimental data which appeared to contradict these results, Maslen, Montie, and Iwasaki showed that significantly better robustness is achievable in "Robustness limitations in self-sensing magnetic bearings" if the magnetic bearing is modeled as a linear periodic (LP) system rather than the linear time invariant (LTI) system used by Thibeault and Smith. The present paper explores why modeling the self-sensing magnetic bearing as a LP system improves the achievable robustness. This is accomplished by utilizing lifting to analyze the LP model as a MIMO discrete LTI system.

“…It is desired from the viewpoint of torque control for sensorless vector control systems for SynRM to orient the principal axis of the frame to the position of rotor salient pole similarly to sensor-used vector control systems [18, 10,11], although a method taking its orientation relative to the position of stator flux has been reported [9].…”

In this paper, a mathematical model of the synchronous reluctance motor in a new form is established, followed by a new analysis of stator linkage flux of the motor, which characterizes the motor and plays an essential role in developing new rotor salient-pole orientation methods for sensorless vector controls. Finally in a unified manner based on the inherent characteristics of the flux, six new potential salient-pole orientation methods are developed and proposed. ©
