20.500.12556/RUL-187215 Modeliranje in simulacija električne deske z vodnim krilom Modeling and simulation of an electric hydrofoil board V tem delu je obravnavano modeliranje in simulacija električne deske z vodnim krilom. Zaradi kompleksnosti takšnega sistema je model omejen na fazo lebdenja, ko je deska že dvignjena nad vodno gladino. Pri modeliranju so upoštevani masa sistema, sila teže, potisk motorja, hidrodinamični upor, vzgon hidrokrila, vertikalno dušenje, pitch momenti ter premik težišča uporabnika kot način regulacije višine lebdenja. Zanemar- jeni so ostali režimi vožnje, vpliv trupa v vodi, Arhimedov vzgon trupa, roll in yaw dinamika ter vpliv valovanja. Rezultati simulacij kažejo, da se sistem pri ustrezno izbranih parametrih regulatorja stabilizira v bližini želene višine. Odziv je odvisen predvsem od dušenja po vertikalni hitrosti in hitrosti premika težišča voznika. Ta parametra določata, kako izrazito sistem niha in kako hitro se po spremembi želene višine ponovno umiri. Občutljivostna analiza pokaže, da hidrodinamični parametri, kot sta vzgonska konstanta hidrokrila in vertikalno dušenje, vplivajo na nagib deske, odstopanje od referenčne višine ter fizikalno smiselnost odziva modela. Izdelani model zato omogoča dober vpogled v povezave med vzgonom, uporom, pitch dinamiko in regulacijo višine deske. This thesis deals with the modelling and simulation of an electric hydrofoil board. Due to the complexity of such a system, the model is limited to the foiling phase, where the board is already lifted above the water surface. The model takes into account the mass of the system, gravitational force, motor thrust, hydrodynamic drag, hydrofoil lift, vertical damping, pitch moments, and the movement of the user’s centre of gravity as a method of controlling the foiling height. Other riding regimes, the influence of the hull in the water, hull buoyancy, roll and yaw dynamics, and the influence of waves are neglected. The simulation results show that, with properly selected controller parameters, the system stabilizes close to the desired height. The response mainly depends on vertical velocity damping and the speed of the rider’s centre of gravity movement. These two parameters determine how strongly the system oscillates and how quickly it settles after a change in the desired height. The sensitivity analysis shows that hydrodynamic parameters, such as the hydrofoil lift coefficient slope and vertical damping, affect the board pitch angle, the deviation from the reference height, and the physical realism of the model response. The developed model therefore provides a good insight into the relationships between lift, drag, pitch dynamics, and height control of the board. električna deska z vodnim krilom modeliranje simulacija regulacija višine stabilnost eFoil modelling simulation height control stability true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-09 11:55:02 2026-09-09 11:55:08 2026-09-11 03:33:59 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 62967 Povh_Neza_-_Modeliranje_in_simulacija_elektricne_deske_z_vodnim_krilom.pdf Povh_Neza_-_Modeliranje_in_simulacija_elektricne_deske_z_vodnim_krilom.pdf 1 A6F1DA000469D19F67E6408D7C3D274F 0d19372488d73a73663945597195c74fd812fc518e58569ce3eea6c275dc252c 84ca8193-ac34-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246717 Fakulteta za elektrotehniko 0 0 0
