Optimiranje izkoristka servo pogona z asinhronskim motorjem : doktorska disertacijaDrevenšek, DušanDisertacija obravnava sktualno temo v raziskavah obratovanja asinhronskih motorjev v povezavi s presmerniškimi napajanji. Motorji so projektirani za optimalno obratovanje z najboljšim izkoristkom v ... okolici nazivne delovne točke, ki je določena z nazivnim vrtilnim momentom, nazivno hitrostjo in nazivnim vzbujanjem. V obratovanju s spremenljivimi veličinami nastopi pri klasičnem vodenju motorja problem znižanja izkoristka pretvarjanja električne energije v mehansko. Izkoristek je zaradi neoptimalne razdelitve izgub najslabši v primeru majhnih vrtilnih momentov. Cilj naloge je bil analiza in sinteza energijsko optimalnega vodenja, ki bi dosegalo maksimalni izkoristek za vse delovne točke. V delu je podana analiza asinhronskega motorja z upoštevanjem izgub v železu. Predlagana je rešitev vodenja z optimiranjem izkoristka temelječega na odločitvi optimalnega rotorskega magnetnega sklepa, ki za vsako delovno točko podano s hitrostjo vrtenja in vrtilnim momentom zagotavlja minimalne izgube motorja oziroma maksimalni izkotistek. Pri tem so bili upoštevani tako zaradi tmperature in magnetnega nasičenja spremenljivi parametri motorja, kot tudi obratovalne meje pogona, ki so podane z maksimalnim tokom in razpoložljivo napetostjo. Za predlagano vodenje z optimiranjem izkoristka je bila izvedena analiza vpliva perturbacij parametrovna izkoristek pogona. Rezultati sinteze so bili potrjeni z izračuni, s simulacijo in tudi eksperimentalnimi rezultati na laboratorijskem pogonu z IGBT pretvornikom in signalnim procesorjem. praktična upraba rezulatov doktorske disertacije je možna pri pogonih električnih vozil, pogonih električnih plovil in ostalih pogonih z zmerno dinamiko.Type of material - dissertationPublication and manufacture - Maribor : D.
