The performance and reliability of BLDC motor drivers have been improved because the conventional control and sensing techniques have been improved through sensorless technology. Then, in this paper sensorless advances are reviewed and recent developments in this area are introduced with their inherent advantages and drawbacks, including the analysis of practical implementation issues and applications. The study includes a deep overview of state-of-the-art back-EMF sensing methods, which includes Terminal Voltage Sensing, Third Harmonic Voltage Integration, Terminal Current Sensing, Back-EMF Integration and PWM strategies. Also, the most relevant techniques based on estimation and models are briefly analysed, such as Sliding-mode Observer, Extended Kalman Filter, Model Reference Adaptive System, Adaptive observers (Full-order and Pseudoreduced-order) and Artificial Neural Networks PB MDPI YR 2010 FD 2010 LK https://uvadoc.uva.es/handle/10324/65781 UL https://uvadoc.uva.es/handle/10324/65781 LA eng NO Sensors, 2010, vol. 10, n. 7, 6901-6947 NO Producción Científica DS UVaDOC RD 23-nov-2024
