The controller is supplemented by feedforward selection of optimized mapping of controllers into voltage source inverter states. This proposed approach of direct inverter control depends on the boundary layer control, and the sign, nominal value and maximal values of the back e.m.f. estimate. It lessens back e.m.f. influence on chattering and makes it possible to extend the field angular velocity range of constant rotor field. Boundary layer control separates variable structure control modes. Supporting praessigned switching order and control objectives is assigned to each attraction domain</dc:description><dc:description xml:lang="sl">Članek obravnava časovno diskretno tokovno regulacijo s spremenljivo strukturo v poljskih koordinatah skupka asinhronski motor - napetostno izvorni pretvornik brez uporabe modulatorja. Regulator je izpopolnjen s predkrmiljenjem izbiranja optimalne preiskave stanj v stanja pretvornika. Ta predlog direktnega krmiljenja pretvornikov je odvisen od režima regulacije in predznaka, minimalne ter maksimalne inducirane napetosti v motorju. Z njo se v veliki meri kompenzira vpliv inducirane napetosti motorja na drhtenje. V primerjavi z običajnimi rešitvami omogoči tudi razširitev vrtne hitrosti pri konstantnem rotorskem polju. Pasovni regulator razmeji režime regulacije s spremenljivo strukturo. Vsakemu režimu predpiše atrakcijsko domeno, ki omogoča predpisano zaporedje preklapljanja in kriterije kvalitete regulacije</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-16SK3WX5"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-16SK3WX5" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-16SK3WX5/8aedc11f-654d-4d39-bb98-8315b3955522/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Strokovno društvo za mikroelektroniko, elektronske sestavne dele in materiale</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-16SK3WX5/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-16SK3WX5" /></ore:Aggregation></rdf:RDF>
