Optimiranje naključno vzbujanih nelinearnih dinamičnih sistemov : doktorska disertacija

Lesnika, Aleš

V delu je predstavljena splošna in učinkovita metoda za optimiranje nelinearnih naključno vzbujanih dinamičnih sistemov z uporabo metod matematičnega programiranja. Zato, da smo lahko optimizacijski ... problem zapisali v ustrezni obliki, smo nelinearnemu naključno vzbujanemu dinamičnemu sistemu najprej pridružili ustrezen deterministični model, kjer smo slučajni vektor stanja opisali z njegovimi statističnimi parametri. Za vpis enačb determinističnega modela smo uporabili tehniko stohastične linearizacije v povezavi s tehniko analize kovarianc. Zaradi kompleksne narave problema smo posebno pozornost posvetili občutljivostni analizi in izpeljali splošne izraze, ki nam omogočajo izračun odvodov statičnih parametrov slučajnega vektorja odziva po projektnih spremenljivkah. Takšen pristop se v primerjavi z do sedaj uveljavljenim načinom numeričnega izračunavanja odvodov pokaže kot zelo učinkovit, saj močno izboljša stabilnost in učinkovitost optimizacijskga postopka. Uporabo metode smo demonstrirali na številnih rešenih zgledih.
