van Beek, Maarten (author)Wind farms experience significant efficiency losses due to the aerodynamic interaction between turbines. A possible control technique to reduce these losses to a minimum is yaw-based wake steering. This thesis investigates the feasibility of this technique by calibrating a surrogate model called the FLOw Redirection and Induction in Steady-state...master thesis 2020

Drubers, Dennis (author)The control of a dedicated ITT system operating human driven MTSs and AGVs can be centralized, decentralized or distributed. The objective of this research is to find which controller structure is best suited for controlling a mixed traffic ITT system. In doing so, performance differences will be reviewed to gain insight into the effect of...master thesis 2020

Jacobs, Olav (author)In this thesis, a control scheme for lifting parcels using two robot manipulators is presented. The robots do not have a rigid grasp on the object. Instead, they use friction to lift the parcels. First, a controller calculates the desired force to make sure the parcels do not slip. The required force, as well as a trajectory are then sent to a...master thesis 2020

van Senden, Jaap Jan (author)The global energy demand is growing, while climate change is demanding a sustainable way of generating this energy. Ocean Thermal Energy Conversion (OTEC) can be a part of the solution for this problem. OTEC generates electricity by using the temperature difference between the surface water of the ocean and the water at 1000 meters depth as a...master thesis 2020

Numan, Bart (author)The integration of variable renewable energy sources (RESs) in the electrical power grid leads to larger and faster variations in the power demanded from controllable power sources. This is a problem, because flexibility of (base load) power plants is limited. Solid oxide reversible cells(SORCs) can be used as load-shifting devices to reduce...master thesis 2020

Orie, Nicolaas (author)This thesis develops dynamical state-space models of the oil market and suggests opportunities for the application of control theory. The emphasis of this thesis is on the modelling, rather than the control theory applications. Most models that are currently employed by oil companies do not model short-term transient responses, but focus on long...master thesis 2020

Spel, Bart (author)Interacting with holograms is something which is widely speculated about. Combining holographic projections with haptic feedback and gesture control might bring this concept closer to reality. This project aims at exploring the possibilities of combining these three technologies into a combined virtual control system. Project owner Safran...master thesis 2019

Mazouz, Rayan (author)Autonomously landing a spacecraft on the surface of a planetary body with a degree of precision in the order of meters is highly challenging. Over the course of time, the landing ellipse, defined as the region with a 99% likelihood of where a space vehicle will land, has improved steadily but currently still has dimensions in the order of...master thesis 2019

Smolders, Arnold (author)Global internet traffic is subject to exponential growth. Free Space Optical communication can accommodate for this increase. Current communication systems prove to be capable of transferring Terabits/s of data per link to and from a satellite. This is done by coupling the laser beam into a fiber, which is connected to a computer capable of...master thesis 2019

Hogervorst, Luc (author)There is a great amount of wave power in earth's oceans. The amount of power harvested for electricity is however very small in comparison to solar and wind. One of the reasons for this is the lack of consensus on the best design of wave energy converters. This thesis develops a novel system design for a wave energy converter array that has...master thesis 2019

Hoogvliet, Jonathan (author)Reinforcement learning (RL) is a model-free adaptive approach to learn a non-linear control law for flight control. However, for flat-RL (FRL) the size of the search space grows exponentially with the number of states, resulting in low sample efficiency. This research aims to improve the efficiency with Hierarchical Reinforcement Learning (HRL)....master thesis 2019
