Bos, R. (author), Giyanani, A.H. (author), Bierbooms, W.A.A.M. (author)Lidars have gained a lot of popularity in the field of wind energy, partly because of their potential to be used for wind turbine control. By scanning the oncoming wind field, any threats such as gusts can be detected early and high loads can be avoided by taking preventive actions. Unfortunately, lidars suffer from some inherent weaknesses that...journal article 2016

Plooij, M.C. (author)Since the industrial revolution, machines have taken over many tasks from humans, increasing labor productivity and prosperity. In the 20th century, the introduction of robots created a second wave of automation, increasing the labor productivity even further. In order to create a third wave of automation, it is necessary to develop a new...doctoral thesis 2015

Nugroho, H. (author)Optical beamforming networks (OBFNs), which consist of many small and flat antennas, called phased array antennas (PAAs), can be tuned such that the signal beam from the airplanes can be steered towards a satellite. This was proposed as a alternative to the mechanically steered antenna, which has many disadvantages. The problem of tuning a large...master thesis 2015

(author)To enhance energy production from methane or resource recovery from digestate, anaerobic digestion processes require advanced instrumentation and control tools. Over the years, research on these topics has evolved and followed the main fields of application of anaerobic digestion processes: from municipal sewage sludge to liquid—mainly...journal article 2015

Bazley, C.M. (author)Every person on the planet lives a significant portion of his or her life in a built indoor environment. Ideally, the built environment serves as protection from the extremes of the outdoor environment and is preferably comfortable. The first ‘built environment’ was a painted cave. The cave served as a shelter and the wall paintings represented...doctoral thesis 2015

Anema, F.J.C. (author)The topic of this study is the control of signalized intersections, specifically the control of switching lanes, which are approach lanes of which the traffic assignment can be changed. When the demand at an intersection varies considerably, being able to change the lane configuration can reduce delay, especially in saturated conditions....master thesis 2015

Koomen, T.J. (author)Shape Memory Alloy (SMA)-based actuators are versatile actuators with a high power-to-weight ratio. These actuators are ideal for applications such as smart wings and smart rotors. However, SMA-based actuators are generally difficult to control, due to a low bandwidth and a hysteretic and non-linear response. The general control framework, or...master thesis 2015

Meijerman, M.J. (author)The number of cars on the road and the need for transportation has increased rapidly during the past decades, leading to an increase of congestion. Traffic congestion and delays lead to high societal costs. Congestion leads to a capacity drop, i.e. the capacity of the road is reduced when congestion sets in. Due to limited financial and physical...master thesis 2015

Linskens, H.T.K. (author)Recent years have seen a steep increase in research being performed towards active space debris removal: space debris has proven to be a very real threat to operational spacecraft, and studies indicate that the frequency of collisions will only increase if nothing is done to remove large pieces of debris. In particular, ESA has done studies...master thesis 2015

Grondman, I. (author)Classical control theory requires a model to be derived for a system, before any control design can take place. This can be a hard, time-consuming process if the system is complex. Moreover, there is no way of escaping modelling errors. As an alternative approach, there is the possibility of having the system learn a controller by itself while...doctoral thesis 2015

Kroes, P.A. (author)My aim is to question whether the introduction of new technologies in society may be considered to be genuine experiments. I will argue that they are not, at least not in the sense in which the notion of experiment is being used in the natural and social sciences. If the introduction of a new technology in society is interpreted as an experiment...journal article 2015

Van Niekerk, H.A.J. (author)The challenge in this thesis is to find out if an off-the-shelf embedded system can replace an off-the-shelf laptop or desktop computer when its task is to perform vision-based velocity control using inverse kinematics on a robotic arm. The results of this thesis are that an algorithm was developed which had to be tested in simulation and should...master thesis 2014

Gebraad, P.M.O. (author)Each wind turbine in a cluster of wind turbines (a wind power plant) can influence the performance of other turbines through the wake that forms downstream of its rotor. The wake has a reduced wind velocity, since the turbine extracts energy from the flow, and the obstruction by the wind turbine rotor causes increased turbulence. If another...doctoral thesis 2014

Holtkamp, G.C. (author)This report deals with the design of a complete guidance, navigation and control system for a planetary lander on Enceladus, for both descent and repositioning. A basic lander model with a main engine, attitude thrusters and a landing gear is presented, for which the equations of motion in different reference frames are derived, including the...master thesis 2014

Voglitsis, D. (author)The utilization of IPT technology in electric vehicles (EVs) charging applications and in the microgrid restoration/islanding mode, has the potential to bring about a change in how EVs are perceived today. Firstly in consumer level, by making the charging process more convenient, safe and user-friendly, by removing the messy cords , and secondly...master thesis 2014

Schwab, A.L. (author), Kooijman, J.D.G. (author)The goal of the Human Power Team from the TU Delft and the Free University of Amsterdam is to break the world speed record in unpaced cycling (Sam Whittingham, 133.28 km/h). The design of such a faired recumbent bicycle is a challenge. The Delft design, called VeloX (Human Power Team (2013)), is a fully-faired monocoque front-driven recumbent...conference paper 2014

Kootstra, P. (author)This thesis investigates whether interval methods can be employed in the construction of a novel controller synthesis algorithm based on backward induction. Interval methods are methods employing interval arithmetic, which is an arithmetic defined on real-valued intervals rather than on real-valued numbers. In the controller synthesis algorithm...master thesis 2014
