The EKF simultaneously estimates the stator stationary axis components ([Formula: see text] and [Formula: see text]) of stator currents, the stator stationary axis components ([Formula: see text] and [Formula: see text]) of stator fluxes, rotor angular velocity ([Formula: see text]), load torque ([Formula: see text]) and [Formula: see text], while the AP-MRAS provides the online [Formula: see text] estimation to the EKF. Both the AP-MRAS, whose adaptation mechanism is developed with the help of the least mean squares method in this paper, and the EKF only utilize the measured stator voltages and currents. Performances of the proposed hybrid estimator in this paper are tested by challenging scenarios generated in simulations and real-time experiments. The obtained results demonstrate the effectiveness of the introduced hybrid estimator, together with a [Formula: see text] reduction in the processing time and size of the estimation algorithm in terms of previous studies performing the same estimations of the states and parameters. From this point of view, it is the first such study in the literature, to our knowledge.<\/jats:p>","DOI":"10.1177\/0142331217734631","type":"journal-article","created":{"date-parts":[[2017,11,28]],"date-time":"2017-11-28T07:21:41Z","timestamp":1511853701000},"page":"3884-3898","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":35,"title":["Novel hybrid estimator based on model reference adaptive system and extended Kalman filter for speed-sensorless induction motor control"],"prefix":"10.1177","volume":"40","author":[{"given":"Ridvan","family":"Demir","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Nigde Omer Halisdemir University, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Murat","family":"Barut","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Nigde Omer Halisdemir University, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,11,28]]},"reference":[{"issue":"2","key":"bibr1-0142331217734631","first-page":"197","volume":"18","author":"Aktas M","year":"2010","journal-title":"Turkish Journal of Electrical Engineering & Computer Sciences"},{"key":"bibr2-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2015.2447731"},{"key":"bibr3-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1007\/s11708-016-0421-y"},{"key":"bibr4-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2012.2236994"},{"key":"bibr5-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1016\/j.enconman.2010.02.037"},{"key":"bibr6-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/ICELMACH.2010.5607797"},{"key":"bibr7-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1016\/j.enconman.2004.04.002"},{"key":"bibr8-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1080\/15325000590896728"},{"key":"bibr9-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2006.885123"},{"key":"bibr10-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1016\/j.enconman.2007.04.026"},{"key":"bibr11-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2007.911956"},{"key":"bibr12-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/ACEMP.2011.6490621"},{"key":"bibr13-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2011.2178209"},{"key":"bibr14-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/9.880631"},{"key":"bibr15-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cta:20060329"},{"key":"bibr16-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2005.862257"},{"key":"bibr17-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1007\/s40313-015-0188-0"},{"key":"bibr18-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/OPTIM.2017.7974999"},{"key":"bibr19-0142331217734631","volume-title":"Digital Signal Processing Fundamentals","author":"Douglas SC","year":"2009"},{"key":"bibr20-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/EPEPEMC.2010.5606803"},{"key":"bibr21-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/60.911412"},{"key":"bibr22-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2007.911209"},{"key":"bibr23-0142331217734631","volume-title":"Adaptive Filter Theory","author":"Haykin S","year":"1996","edition":"3"},{"key":"bibr24-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2002.800726"},{"key":"bibr25-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2005.862324"},{"key":"bibr26-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1049\/iet-rpg.2014.0376"},{"key":"bibr27-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1049\/iet-epa.2014.0220"},{"key":"bibr28-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1016\/j.enconman.2012.06.020"},{"key":"bibr29-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1002\/acs.874"},{"issue":"5","key":"bibr30-0142331217734631","first-page":"853","volume":"18","author":"Ozsoy EE","year":"2010","journal-title":"Turkish Journal of Electrical Engineering & Computer Sciences"},{"key":"bibr31-0142331217734631","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2015.2453350"},{"key":"bibr32-0142331217734631","first-page":"1008","volume-title":"Proceedings of the 24th annual conference of the IEEE industrial electronics society, 1998.
