V okviru diplomske naloge smo preučili možnosti vizualizacije rezultatov modeliranja hidravličnih dinamičnih sistemov v okviru programa Matlab. Ker smo vizualizacijo želeli dopolniti tudi z video posnetki, smo kot ustrezno orodje izbrali program VEGAS Movie Studio. V uvodnem poglavju diplome smo najprej opisali naloge, ki so motivirali delo. Sledi opis pomembnejših značilnosti programa VEGAS Movie Studio. Nato smo podali podrobnejšo predstavitev štirih hidravličnih sistemov. Posebej natančno smo opisali prvega med njimi. Gre za hidravlično pilotno napravo, ki se nahaja v Laboratoriju za avtomatiko in kibernetiko Fakultete za elektrotehniko Univerze v Ljubljani. Za to napravo smo podrobno opisali izvedene korake kombiniranega pristopa k modeliranju. Sledi opis realizacije animacije ter razširitev ilustracije delovanja, ki je podprta z ustrezno pripravljenimi video posnetki. Poglavja 3 do 5 slonijo na predstavitvi različnih načinov delovanja hidravlične pilotne naprave AMIRA 200 DTS. V omenjenih poglavjih smo najprej opisali že nasvete uravnotežene modele izbranih načinov delovanja, nato pa smo predstavili tudi razvoj funkcij za animacijo izbranih sistemov. Razvite datoteke smo uredili s pomočjo grafičnega vmesnika tako, da lahko uporabnik na preprost način opazuje učinke modeliranja in vizualizacijo, hkrati pa tudi najde datoteke, ki so poskrbele za izbran prikaz. In this diploma thesis, we examined the possibilities of visualizing of modelling results regarding hydraulic dynamic systems in the programme Matlab. We investigated also the options of combination of animation results with video presentation of the real system. For this goal also the programme VEGAS Movie Studio was used as a suitable tool for needed operations. In the introductory chapter the tasks that motivated this work are presented. This is followed by a description of the most important features of the programme VEGAS Movie Studio. Then four hydraulic systems are introduced. Very detailed description of the first one is given in the Chapter 3. This is a hydraulic pilot device located at the Laboratory of Control Systems and Cybernetics at the Faculty of Electrical Engineering, University of Ljubljana. For this device all needed design steps are described when using combined modelling approach. This is followed by a description of the developed animation results and also by the illustration how combined presentation is possible taking into account both developed animation results and video presentations of the real system operation. Chapters 3 to 5 present different operation modes of the AMIRA 200 DTS hydraulic pilot device. In these chapters first corresponding mathematical models are described, while later on also all developed programmes are given and illustrated with corresponding animation results. To enable user friendly observation of the operation of all developed programme files graphical user interface was generated. The user can observe all the features of developed modelling results and corresponding visualization by simply pushing the prepared buttons in the suitable level of this interface.
