Sopar, Luca (author)
With the increasing concerns of the emission of greenhouse gases and other pollutants and the push towards sustainable and greener means of transportation, there is a need for new drive systems running on alternative fuels. One fuel that holds significant potential as a marine fuel for the future is methanol. When produced utilising carbon...

Event-Triggered Control (ETC) is a control method where the controller is only updated when necessary. The control inputs are kept fixed until a state-dependent event triggers their re-computation. The triggering condition is designed to guarantee the stability and desired performance of the control system. This prevents the excessive use of...

The world is moving towards sustainability and there is immense pressure on Aerospace Industry to reduce its emissions to contribute to a carbon-neutral world. However, maturing gas turbine technology is a big bottleneck towards this goal and hence, this project focuses on the technical and economic feasibility of a new type of propulsion system...

Road users still encounter unnecessary delays due to inefficient traffic control in urban traffic networks. These delays are ever-increasing and have large environmental and economic consequences. In the Netherlands, most intersections are controlled using actuated controllers, which respond directly to the current traffic demand obtained from...

Ammonia (NH3) may reduce CO2 emissions from the marine industry as it is carbon-free and more energy-dense than hydrogen or batteries. Pure ammonia exhibits poor combustion characteristics, so several researchers have already operated small-scale internal combustion engines (ICEs) with ammonia-hydrogen blends. However, nitrogen oxides NOx and...

With the rise of various renewable energy sources, comes the possibility for combining the different type of sources together to balance their shortcomings. The goal is to find a renewable energy system that can be reliable year-round and be accessible for everyone. This research tries to model such a system. A model of a grid-tied PV-battery...

Active hand prostheses aid people, who suffer from an upper limb deficiency, in performing activities of daily living. The two types of active hand prostheses available are the myo-electric prosthesis and body-powered prosthesis. Even though both allow a user to grasp objects, the downsides are major. The high actuation...

The International Maritime Organization (IMO) has imposed strict emission guidelines for the shipping industry to meet the Paris agreement. This has led the maritime industry to search for alternative fuels and prime movers. An electric propulsion system powered with a Solid Oxide Fuel Cell (SOFC)-Internal Combustion Engine (ICE) is one of the...

Brouwer, Patriek (author)
Our present-day society is utterly dependant on electricity. This dependence will only grow as electrification of sectors such as manufacturing, transportation and building heating takes off. Most of the electricity these days comes from conventional plants running on coal and natural gas. Despite that these are reliable and cheap, the...

Climate mitigation measures are integrated in various governmental and commercial initiatives. The sector of electrification and energy is no exception to this. For remote island communities however, the access to reliable and affordable electricity comes with additional difficulties. The effects of climate change, energy dependency and...

System identification for switched linear systems from input output data has received substantial attention in recent years. There is a growing interest for techniques that pose the identification problem as a sparse optimisation problem. At the same time a vast amount of research is dedicated to improving SAT solvers which as a result become...

Emissions restrictions imposed by the International Maritime Organization (IMO) is forcing ship owners and builders to look into alternative fuels and prime movers. The high efficiency of fuel cells could help to decrease emissions in marine power generation. Solid oxide fuel cells (SOFCs) are the most fuel flexible among fuel cells, the high...

A wet clutch is a device that transfers torque between two shafts via a hydraulic mechanism. Wet clutch control is key to achieve smooth and fast clutch engagements. Optimal control of a wet clutch is not trivial because of the complexity of the system due to nonlinearities, hybrid dynamics and changing dynamics over time due to changing...

In The Netherlands, the current heat energy system accounts for 44% of the primary energy usage and relies almost entirely on fossil fuels such as natural gas. To meet the Paris Climate Agreement goals, 4th Generation District Heating (4GDH) networks are expected as sustainable heat energy system solution. The concept relies on optimally...

The detection of unusual behavior plays a crucial role in the prevention of illegal and harmful activities such as smuggling, piracy, arms trading, human trafficking and illegal immigration. Also for military applications, it is useful to detect anomalous behavior to provide an alert for potential threats, especially with the more recent...

In the year 2050, global anthropogenic radiative forcing from aircraft emissions are projected to increase significantly. Recent studies have considered climate optimized flight trajectories to be a promising measure to mitigate non-CO2 emissions’ environmental impact, which is highly sensitive to locus and time of emissions. Estimating the...

This project’s research question is: How is society able to organize a mental healthcare system, that serves people’s individual care needs and is collectively economically viable? This research question regards a business model on a system level and the hybridity is reflected in the tension between the individual interest of fulfilling a care...

New technologies are being developed to produce electricity cleaner and more efficient. A promising technology among these is the solid oxide fuel cell (SOFC). It electrochemically converts chemical energy into electricity. This process is highly efficient and several types of fuel are suitable. Furthermore, the SOFC operates at a high...

Disturbances are an important factor in the performance of complex large scale systems. These complex large scale systems can be modeled by a broad class of hybrid dynamical systems. The current practice of controlling such processes is one way, from the scheduling level to the control level. The performance of these complex systems can be...

Energy flexibility is the ability to change power production or consumption over time. It is required for a power system to function properly, to balance supply and demand. Currently, the largest providers of energy flexibility in the Netherlands can be found on the supply side and consist mainly out of fossil fueled power plants. As these are...
