Návrh navedení, navigace a řízení pro vertikální přistání opakovaně použitelného raketového urychlovače / Design of Guidance, Navigation and Control for Vertical Landing of a Reusable Rocket Booster

Király, Adrián January 2021 (has links)
Táto diplomová práca sa zaoberá vývojom systému pre navádzanie, navigáciu, a riadenie pre znovupoužiteľný raketový urýchľovač. Pre dosiahnutie tohto cieľu bol vytvorený simulačný model rakety v prostredí Simulink. Na základe dát získaných pomocou CFD softvéru bol pre túto simuláciu vytvorený tiež vlastný aerodynamický model. Pre účely demonštrácie dosiahnutých výsledkov bol ako súčasť práce tiež naprogramovaný interaktívny 3D vizualizačný nástroj.

Guidance and Control for Launch and Vertical Descend of Reusable Launchers using Model Predictive Control and Convex Optimisation

Zaragoza Prous, Guillermo January 2020 (has links)
The increasing market of small and affordable space systems requires fast and reliablelaunch capabilities to cover the current and future demand. This project aims to studyand implement guidance and control schemes for vertical ascent and descent phases ofa reusable launcher. Specifically, the thesis focuses on developing and applying ModelPredictive Control (MPC) and optimisation techniques to several kino-dynamic modelsof rockets. Moreover, the classical MPC method has been modified to include a decreasingfactor for the horizon used, enhancing the performance of the guidance and control.Multiple scenarios of vertical launch, landing and full fligth guidance on Earth and Mars,along with Monte Carlo analysis, were carried out to demonstrate the robustness of thealgorithm against different initial conditions. The results were promising and invite tofurther research.
