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.<\/jats:p>","DOI":"10.3390\/s100706901","type":"journal-article","created":{"date-parts":[[2010,7,20]],"date-time":"2010-07-20T07:26:17Z","timestamp":1279610777000},"page":"6901-6947","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":234,"title":["Position and Speed Control of Brushless DC Motors Using Sensorless Techniques and Application Trends"],"prefix":"10.3390","volume":"10","author":[{"given":"Jos\u00e9 Carlos","family":"Gamazo-Real","sequence":"first","affiliation":[{"name":"Department of Signal Theory, Communications and Telematic Engineering, University of Valladolid (UVA), 47011 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ernesto","family":"V\u00e1zquez-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Department of Signal Theory, Communications and Telematic Engineering, University of Valladolid (UVA), 47011 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3333-0148","authenticated-orcid":false,"given":"Jaime","family":"G\u00f3mez-Gil","sequence":"additional","affiliation":[{"name":"Department of Signal Theory, Communications and Telematic Engineering, University of Valladolid (UVA), 47011 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2010,7,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"595","DOI":"10.1109\/TIA.1985.349715","article-title":"Microcomputer Control for Sensorless Brushless Motor","volume":"IA-21","author":"Iizuka","year":"1985","journal-title":"IEEE Trans Ind Appl"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"402","DOI":"10.1109\/41.3113","article-title":"High-Speed Torque Control of Brushless Permanent Magnet Motors","volume":"35","author":"Becerra","year":"1988","journal-title":"IEEE Trans.
