Pérez Moreno, Carlos (author)FOWTs pose several control challenges. This work addresses reduced order modelling of FOWT to develop an MPC. They key objective is tackle the platform pitch instability while improving the performance in other KPIs. An existing reduced order model, which considers platform pitch and surge, and rotor speed DOFs is adapted and extended, with...master thesis 2023

Pfeiffer, Marijn (author)To overcome the problem of wave-induced vessel motions on the crane tip, technologies have been developed to compensate for these motions. Most vessels nowadays, are equipped with dynamic positioning systems, these systems reduce the yaw, surge and sway movement of the vessel. This leaves, the motions roll, pitch and heave uncompensated. To...master thesis 2022

Pollack, Justin (author)Nowadays, machine learning (ML) methods rapidly evolve for their use in model-based control applications. Model-based control requires an accurate model description of the dynamical system to reassure the performance of the controller. Conventionally, this model description is retrieved from first-principles modelling which can be problematic if...master thesis 2022

Halvorsen, Stijn (author)Wind energy plays an essential role in the transition to a sustainable future and wind turbines allow us to utilize it. Wind turbines are often installed in close proximity to make the best use of the given space and to save costs. This also has the disadvantage that the turbines influence each other due to wakes. This is where wind farm control...master thesis 2022

Robeerts, Tori (author)Twisted and coiled polymer muscles (TCPMs) show promise to function as artificial muscles, because of their lightweight, low cost, large contraction, and respectively low hysteresis. A TCPM contracts when it is heated and extends when it is cooled. Different modeling and controlling techniques have been implemented. \cite{VanDerWeijde_2019}...master thesis 2021

Verkamman, Sjors (author)Boost-type power factor correction (PFC) rectifiers can be used in, for example, battery charging systems for Electric Vehicles (EVs). Conventionally available three-phase PFC rectifiers are limited to output 1/3 of the rated power when connected to a single-phase mains. This work presents the research into the single-phase operation of the...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
