Analiza dinamike pogonske zveze asinhronskega elektromotorja in hidravlične zobniške črpalke : doktorska disertacijaKastrevc, MitjaPovečana zavest o varovanju okolja je tudi na inženirskem področju pripeljala do prevrednotenja ustaljenih konceptov pogonskih sistemov še posebej z vidika varčevanja z energijo, prijaznosti do ... okolja in znižanju hrupa. V tem smislu je tudi pri hidravličnih pogonih postavljena zahteva, da se hidravlična črpalka prilagaja trenutnim potrebam porabnika. Z vidika cenenosti je zanimiv pogon hidravlične črpalke s konstantno iztisnino, gnane z asinhronskim elektromotorjem s spreminjanjem vrtilne hitrosti. Doktorska disertacija obravnava pogonsko zvezo med hitrostno-nastavljivim asinhronskim elektromotorjem in ceneno zobniško hidravlično črpalko. V prvem delu je razvit podroben model dinamičnega obnašanja običajnega asinhronskega motorja in dinamičnega obnašanja hidravlične zobniške črpalke in cevovoda. V drugem delu je potrjena veljavnost matematičnega modela s pomočjo eksperimenta. V nadaljevanju je izvedena regulacija tlaka v zaprti zanki s pomočjo klasičnega PID regulatorja. Razvit je nov tip mehkega regulatorja s PID-regulatorju podobnim dinamičnim obnašanjem. Nelinearne lastnosti tega regulatorja so realizirane z eno bazo pravil, vendar z različnimi izhodnimi množicami za PI in PD del regulatorja. Takšen regulator omogoča stabilno delovanje preko celotnega delovnega območja in je uporaben za industrijsko prakso.Type of material - dissertation ; adult, seriousPublication and manufacture - Maribor : [M.
