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 Junta de Castilla y León (VA034A10-2) application/pdf eng MDPI info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/3.0/ © 2010 The Authors Attribution 3.0 Unported Sensorless control Artificial intelligence BLDC motor Electronic processors Hall-effect sensors Motores BLDC Procesadores electrónicos Sensores de efecto Hall 3306 Ingeniería y Tecnología Eléctricas Position and speed control of brushless DC motors using sensorless techniques and application trends info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.mdpi.com/1424-8220/10/7/6901 SI
