Considering the inherent uncertainty of structural geological models, the non-uniqueness of geophysical inverse problems, and the growing availability of data, there is a need for methods that combine different types of data and allow for updating knowledge in a consistent way. By making use of the development of efficient, gradient-based MCMC...

Performance of set based fault detection is highly dependent on the complexity of the set bounding methods used to bound the healthy residual set. Existing methods achieve robust performance with complex set bounding that narrowly define healthy system behavior, yet at the cost of higher computation times. In this thesis a major improvement is...

A switching max-plus linear model is a framework to describe the discrete dynamics of the timing of events. To influence these systems one can choose the routes of jobs and the orderings of operations as input for the system. In this thesis the techniques of model predictive control are used to find good input values. The problem of finding the...

Today’s increasing complexity, rising interconnectivity and larger systems in engineering require new approaches and methods for effective engineering. This is also the case for the technological installation in infrastructure sector (TII), which designs technical systems for infrastructural civil structures. To assist in engineering, Model...

Commercial heavy vehicles are especially prone to rolling over due to their inherent properties, such as the high centre of gravity - track width ratio and compliant chassis frame. Autonomous trucks cannot become widespread without eliminating this danger by guaranteeing rollover-free vehicle motion. Currently existing Roll Stability Control...

Current and future space missions require agile and reliable spacecraft capable of trailing and keeping the required attitude. Most of the agile spacecraft missions are near-Earth based but some are placed far away from Earth and its influence. One example of such missions is the Athena mission, which requires the spacecraft to perform fast and...

Autonomous driving is a development that has gained a lot of attention lately, because it can lead to major improvements in the mobility sector. One example of a research project that aims to develop vehicles that are capable of reaching the highest level of autonomy in driving, is the WEpods project. The goal of this research is in line with...

A variable speed AC motor drive, fed by a 3-phase AC supply, often consists of a 3-phase bridge diode rectifier, a DC link capacitor and a pulse width modulated inverter. Recently, a new type of capacitor known as film capacitor or slim capacitor has become popular for use in DC link. This capacitor has a lower value of capacitance and a longer...

This thesis reports on the research and design of a real-time Time-Varying Model Predictive Control (TVMPC) scheme to stabilize a tilt-rotor aircraft with four independently tilting rotors. The aircraft design stems from a prototype system constructed by the drone technology start-up Avy.<br/>First, a motivation is presented for implementation...

Space mission design is an activity that deals with a highly complex, non-linear system of which the requirements and characteristics are subject to regular change. This has consequences on the mathematical design but also the translation to hardware. In this thesis, we explore the use of Integrated Mission Design (IMD); a data-driven design...

In this thesis, we investigate a sparse basis for ultrasound images, so that we can use sparse regularization in imaging. Actually, there are few previous researches explicitly demonstrating that medical ultrasound images can be sparsified for some dictionary. We consider various orthogonal transforms such as wavelet transforms, cosine...

Market organisation on energy networks is increasingly complex due to frequent emergence of new markets within and related to energy infrastructure. This research is conducted in cooperation with the Dutch Ministry of Economic Affairs and Climate Policy, and analyses the impacts of role demarcation policies on the development of the electric...

Access to electricity still lacks for a fifth of the world's population. Most of the areas are in the remote rural location. Due to the off-grid location, policies, and other social factors, the grid expansion in these areas is not economically viable. Installing Solar Home Systems (SHS) is considered to be a promising immediate solution, given...

The Ampelmann system offers a safe and reliable solution for offshore access. As safety is a key factor, an extensive safety and warning management system is employed which accommodates for different fault types that may occur. Accommodation of sensor failure in the Ampelmann system is currently done through switching to a redundant component....

One of the main goals of laminar flow control is to reduce skin-friction drag by delaying the onset of laminar to turbulent transition. Over unswept wings, the leading cause of this is the growth of flow instabilities called Tollmien-Schlichting(TS) waves. This thesis aims to test the feasibility and performance of a designed Linear Quadratic...

This thesis report proposes a framework to implement Navigation, Guidance and Control (GNC) systems, that enable point-to-point autonomy for displacement vessels. A model-based control approach is chosen as the basis of the GNC systems. The resulting algorithms are implemented for verification in a 1:25 scale model of a Azimuth Stern Drive (ASD)...

Electricity is a basic need in today`s society, being present in almost every aspect of life. The extensive infrastructure that transports electricity to the consumers, is expected to always work. At the same time there is a growing realism that the energy sector needs to modernise and ‘greenify’, in order to become more climate friendly. This...

Representation learning is a central topic in the field of deep learning. It aims at extracting useful state representations directly from raw data. In deep learning, state representations are usually used for classification or inferences. For example, image embedding that provides similarity metrics can be used for face recognition. Recent...

Wind power to cold climate sites is attractive because of favorable wind conditions and low population density. However, icing of wind turbine blades remains one of the main challenges for cold climate sites. Ice formation on wind turbine blades causes several problems, such as the loss of power production, unbalanced loads in drive train and...

Current trailers and caravans use overrun brakes, which cause overheated brakes in the mountains. A solution is to design an electric brake system in which the brakes are controlled electronically instead of mechanically. The report discusses the control models associated with braking, anti-sway detection and velocity sensor fusion. The RDW...
