  • Adaptiv regulering av fly 
    Algarheim, Thomas (Master thesis / Masteroppgave, 2010)
    Denne oppgaven gikk ut på å lage en matematisk modell av et fly som hadde varierende stabilitet i forhold til angrepsvinkelen. Deretter ble det utviklet en adaptiv regulator som ga en raskere referanseforfølging enn en ...
