Does, Luc (author)In this thesis, the design and implementation of an improved current controller for grid-tied converters is discussed. Using this improved current controller, a power factor correction test platform achieves practically zero AC and DC error in steady-state. The power factor corrector accomplishes this by utilizing the parallel combination of a...master thesis 2019

Ripoll Sanchez, Andrés (author)There is no doubt that the smallest spacecraft platforms (CubeSats, NanoSats and microsats) are revolutionizing the market. The possibilities of developing spacecraft through standard platforms, commercial of the shelf components and then reduced the costs of development has allowed new organizations to enter the space section. On top of that,...master thesis 2019

Hutters, Coenraad (author)The Utility Lagrangian and the Surplus Hamiltonian in economic engineering do not depend on consumption.<br/>Two theories are proposed to include the effect of consumption in the Utility Lagrangian and the Surplus Hamiltonian. The second of these two theories resolves the dissipation obstacle in port-Hamiltonian systems as an additional result....master thesis 2019

Lucassen, Koen (author)An analysis of attitude controller concepts, including four attitude flight controllers, for the re-entry of the HORUS-2b. The four concerning attitude flight controller concepts are the benchmark Linear Quadratic Regulator (LQR), Model predictive Controller, Incremental Non-linear Dynamic Inversion (INDI) and Sliding Mode Controller. Each...master thesis 2019

van der Geest, Lars (author)This thesis report is focused on the design of a guidance and control system that is able to minimize the deviation from the desired impact point for a firing range of 1 kilometer, given a 30mm spinning gun-launched projectile with a novel actuator design. This actuator is fixed on the projectile and offers a single force that can only be...master thesis 2019

Singh, Sunayna (author)The space environment is ever-changing with space structures getting larger and the orbits getting increasingly crowded with time. This creates a need for removal of large defunct satellites to avoid the disastrous Kessler syndrome, which poses a major threat to the future of space exploration. This research examines the dynamics and control...master thesis 2019

Anckaert, Jorg (author)Spaceplanes are the future of space travel and launching objects into space. They are fully reusable, and provide a lot of flexibility to a mission. This thesis focuses on the propulsion system and its impact on the stability and control of a spaceplane. The main research question is: "Which parameters and deficiencies in the propulsion system...master thesis 2019

Crepy-Marglais, Jean-Daniel (author)Nowadays, a satellite is considered as out of range forever once it is launched. This may soon no longer hold thanks to on-orbit servicing. However, the complexity of that topic makes it highly challenging on many aspects. On-orbit servicing using a robotic arm is nonetheless the most investigated technology in order to achieve the berthing of...master thesis 2018

Meulenbeld, Joost (author)Previous years have seen a rise in the use of Unmanned Aerial Vehicles (UAVs). Reaching a large endurance and range while being able to perform Vertical Take-Off and Landing (VTOL) landings allows a broad range of applications. For this purpose the DelftaCopter (DC) was developed, a tilt-body tailsitter UAV. It hovers using a single helicopter...master thesis 2018

Facchinelli, Michele (author)The amount of propellant required to perform deep-space maneuvers usually consists of a large percentage of the total spacecraft mass. In the early '90s, a new technique was experimented at the end of the Magellan mission, which employed the atmosphere of Mars itself, to reduce the eccentricity of the orbit over a long period of time. Said...master thesis 2018

Sarvary, Anaïs (author)The thesis is focused on Paris and the notion of power, prevailing in the city. It is more particularly looking at the experience of control felt within it and how it is possible to design in resistance to this particular aspect.<br/>The graduation was developed along different methodologies and themes of interest. <br/>The research, set at the...master thesis 2018

Grazian, Francesca (author)The Wireless Power Transfer (WPT) has been introduced decades ago for low power applications, and more recently, it has been used for industrial high power applications. WPT is gaining popularity because it presents several advantages over the power transfer through cable, such as the galvanic insulation between the power source and the load,...master thesis 2018

de Groot, Sjoerd (author)The goal of this thesis is to present a framework which can be used to optimize the observer and controller performance by placement of sensors and actuators on a continuous domain. The framework provides choices of model structure, cost functions and optimization methods to perform the placement. Systems which would be suitable for the use of...master thesis 2018

Pijnacker, Joris (author)Because of the increasing e-commerce volume, resulting in increasing demands on the speed of delivery, logistical processes become more and more automated. Order picking is one of the last tasks that is done by humans in warehouses, because humans are flexible with respect to the large variability and changeability in items. However, it is a...master thesis 2018

Coroli, Iurie (author)When acquiring information using imaging techniques, one wants to achieve the best possible resolution in order to obtain valuable results. In the ideal scenario the size of the smallest resolved object features is limited by the wave properties of light, with a number of techniques developed to overcome this limit. In real life measurements the...master thesis 2018

Baron, Koen (author)Tall buildings lose a big part of their expensive space to elevator shafts. A ropeless elevator reduces the amount of shafts, because multiple cabins are able to move in the same shaft. Currently an elevator using a row of linear motors along the shaft is in the end phase of development. Tests on a full scale prototype 5 have proven the concept....master thesis 2018
