Dutruel, Benjamin (author)The startup Rocket Factory Augsburg (RFA) is developing the RFA ONE orbital launch vehicle. A significant hurdle for its closed-loop guidance is the need to fully deplete the third stage for insertion during the first flight, which results in lengthy burn-arcs and complexity not managed properly by traditional guidance algorithms. Additionally,...master thesis 2023

Riti, Cristina (author)Insertion maneuvers are used to move a spacecraft from an open orbit (parabolic or hyperbolic) into a closed orbit around a target body. These maneuvers are key components in any space mission considering orbiting a body for a large amount of time, for exploration or landing; the hyperbolic orbit will be the one that will be used to transfer...master thesis 2023

Çavdar, Irmak (author)The development of reusable launch vehicles in space exploration is a significant paradigm shift in the aerospace industry. Among numerous approaches to fully reusable launchers, a flyback booster, complemented by the emerging importance of spaceplanes, stands out as a viable solution. To outweigh the drawbacks associated with the cost, a...master thesis 2023

Fernández Martín, Enrique (author)Temporarily Captured Orbiters (TCOs) - also known as Earth’s mini-moons – are meter-size asteroid fragments temporarily trapped in the Earth-Moon system. TCOs are challenging to identify due to their small size and high speed. While only two TCOs have been confirmed so far, studies suggest a constant presence of at least one TCO at any given...master thesis 2023

van der Drift, Victor (author)This thesis presents a comprehensive approach to integrating a trajectory planner and follower for autonomous vehicles (AVs) using model predictive contouring control (MPCC). The planner generates collision-free trajectories with a kinematic bicycle model, while the follower tracks them using a dynamic bicycle model with a smaller integration...master thesis 2023

LIU, Xinjie (author)Many autonomous navigation tasks require mobile robots to operate in dynamic environments involving interactions between agents. Developing interaction-aware motion planning algorithms that enable safe and intelligent interactions remains challenging. Dynamic game theory renders a powerful mathematical framework to model these interactions...master thesis 2023

van Loon, Joaquin (author)Situational awareness within port areas is crucial to avoid collisions, navigate efficiently and reduce congestion. Maritime-traffic controllers constantly monitor the situation in the port and intervene when needed. This study proposes a deep learning model that predicts future vessel positions to assist in this process. The model employs a...master thesis 2023

Martens, Bruno (author)Critical to the safe application of autonomous vehicles is the ability to accurately predict the future motion of agents surrounding the vehicle. This is especially important - and challenging - in urban traffic, where vehicles share the road with Vulnerable Road Users (VRUs) such as pedestrians and cyclists. However, the majority of the...master thesis 2023

Rado, Karlo (author)A key challenge for SaR robotics is to avoid dynamic obstacles in cluttered environments, with limited and noisy information. In this research, a controller for SaR robots is developed by coupling a local heuristic motion planner with a model predictive control (MPC) based trajectory tracker. Constraint tightening and tube-based control are used...master thesis 2023

Bărbulescu, Liliana (author)Robot manipulators are significantly more accurate than their human counterparts and enhance the repeatability of various tasks. However, manufactures still provide reduced information regarding the robot controller functions, typically affecting robots' predictability. Additionally, industrial examples show that system transparency could be...master thesis 2023

Klomp, R.E. (author)THE increasing demand in worldwide air travel is foreseen to push the limits of capacity of the current Air TrafficManagement (ATM) system within the coming decade. Therefore, twomajor international programs have been initiated to fundamentally restructure the way in which Air Traffic Control (ATC) is performed. A key pillar in both programs is...doctoral thesis 2023

van Selling, Stijn (author)The Dutch Air Traffic Control has implemented fixed approach trajectories within approach control during night operations when traffic density is low. During the day, when traffic density is higher, vector-based operations are used. The Dutch Air Traffic Control aims to implement fixed approach trajectories when traffic density is high. This...master thesis 2023

van der Velde, Geert (author)For increasing the safety of quadcopters the development of recovery control algorithms is crucial. A common cause of quadcopter crashes is collisions. To validate recovery control algorithms on collisions, the quadcopter has to reach the post-collision state. <br/>For this, the principle of 'endpoint control' is introduced, bringing the...master thesis 2023
