From the perspective of further reducing the system cost and realizing high-performance vector control, the book takes the surface mounted PMSM as the research object and studies the phase current sampling reconstruction technology and sensorless control technology. Aiming at the chaotic control problem with uncertain parameters of the PMSM operating system, this paper designs an adaptive sliding mode chaotic control algorithm based on the adaptive control theory. The uncertain parameter model of the PMSM system is established. The parameter uncertainty defines the tracking error of each...

Benefiting from advancements in power electronics and automatic control technologies, the Permanent Magnet Synchronous Motor (PMSM) has emerged as a pivotal drive component in industrial automation, renewable energy, and aerospace applications, owing to its high power density, rapid dynamic response, and sensorless operation potential. However, challenges persist in achieving reliable full-speed-range (zero-low to high-speed) sensorless control due to limitations of single-method adaptability and mechanical sensor-induced cost and reliability issues. This study proposes a hybrid sensorless...

Diese Veröffentlichung wurde durch die Unterstützung des Nantong Institute of Technology ermöglicht. Bürstenlose DC-Motortreiber sind Kernkomponenten in der modernen industriellen Automatisierung und intelligenten Geräten. Ihre Leistung bestimmt direkt die Reaktionsgeschwindigkeit, die Positioniergenauigkeit und die Betriebslebensdauer des gesamten Antriebssystems. In der Praxis stehen Konstrukteure jedoch oft vor der Herausforderung, dass die Parameterauswahl schwierig, die Verdrahtung fehleranfällig und die Fehlersuche zeitaufwändig ist: Fehlende Motortypenschilder führen zu einer...

This publication was made possible through the support of Nantong Institute of Technology. Brushless DC motor drivers are core components in modern industrial automation and intelligent equipment. Their performance directly determines the response speed, positioning accuracy, and operational lifespan of the entire actuator system. However, in actual engineering applications, designers often face the challenges of "difficult parameter selection, prone to wiring errors, and time-consuming debugging": missing motor nameplates lead to inaccurate estimation of rated current, reversed Hall sensor...

Cette publication a été rendue possible grâce au soutien de l'Institut de technologie de Nantong. Les pilotes de moteurs à courant continu sans balais sont des composants essentiels de l'automatisation industrielle moderne et des équipements intelligents. Leurs performances déterminent directement la vitesse de réponse, la précision du positionnement et la durée de vie opérationnelle de l'ensemble du système d'actionnement. Cependant, dans les applications techniques réelles, les concepteurs sont souvent confrontés aux défis suivants : "sélection difficile des paramètres,...
