This thesis studies ways of broadening the range of a piezoelectric flow induced vibration harvester. The proposed device consists of a flap connected with a hinge to a spring. Existing harvesters are designed to replace or charge batteries for low power systems in the range of milliwatts. These systems produce low amounts of power, but for low...

Congestion is one of the big annoyances people experience in their everyday life. Furthermore, congestion has negative effects on both the environment and the economy. In short, it forms a very big problem to society. This thesis focuses on a specific type of congestion, namely a ‘wide moving jam’. This is typically a short jam that propagates...

Increasing the capacity of offshore wind energy is a necessary step in the transition from fossil fuels to renewable energy sources. In order to accelerate this process, the costs of wind energy should be reduced to make it more competitive with traditional energy sources. Cost reduction could be achieved by increasing the lifetime of an...

The increasing penetration of wind power generation introduces uncertainty in the behaviour of electric power grids. This work is concerned with the problem of day-ahead reserve scheduling (RS) for power systems with high levels of wind power penetration, and proposes a novel set-up that incorporates an alternating current (AC) Optimal Power...

The use of robotic systems outside the branch of tasks currently common in industry requires the development of novel intelligent control methods. In this thesis we will aim to improve on a recent machine learning method known as active reward learning. This method is able to teach a robotic system a task using human expert ratings on...

Due to the increase of elderly people, the number of hip fractures rises as well. The most common hip fracture is an intertrochanteric fracture. This fracture is treated by inserting an intramedullary nail to support the fractured femur fragments. Before the intramedullary nail can be inserted, the bone fragments need to be realigned by...

A principal-agent problem is a mathematical framework for modelling contractual relationships, where a principal delegates tasks to an agent in exchange for reward. Many real life contracts are of this type. The agent does not have the same objectives as the principal and he possesses hidden information. Two types of hidden information is...

Infrastructure managers outsource maintenance activities to maintenance service contractors. This gives rise to misalignment between a contractor's short-term objectives and an infrastructure manager's long-term objectives. Infrastructure managers have started to explore various forms of contracts in which they incentivize contractors to work in...

Corrective osteotomy is the treatment for malunion of bone segments, which is required after insufficient fracture management. To perform this procedure adequately, 3D imaging is used to make a virtual plan of the osteotomy. In order to transfer this virtual plan to the patient in the operating room, a navigation method is required. Existing...

This thesis aims to combine visual data and distance measurements from a Laser Range Finder (LRF) to recognise the presence of humans. The data from the LRF is used to find regions of interest in order to reduce the load on the visual data analysis. Deep learning convolutional neural networks have shown incredible results on visual recognition...

A recent trend in robotics is aimed at the cooperation between human and robot. This has led to an increased development of collaborative robot manipulators. Typical characteristics of collaborative robots are their user-friendly and lightweight design, innovative compliant mechanics, the implementation of various safety features and advanced...

Reaction Wheels (RWs), the primary attitude actuators on most spacecraft, are one of the largest on-board disturbance sources due to nondeterministic bearing behaviour at low angular velocities of the RWs. The configuration design of redundant Reaction Wheels Arrays (RWAs) can be divided into configuration optimization and control allocation....

In order to interact with environments and appliances made for humans, robots should be able to manipulate a large variety of objects and appliances in human environments. When having experience with manipulating a certain object or appliance, a robot should be able to generalize this behaviour to novel, but similar objects and appliances. When...

Wind turbines are often sited together in wind farms as it is economically advantageous. However, the wake inevitably created by every turbine will lead to an aerodynamic interaction between the individual turbines. Common practice in industry has been to control turbines individually and ignore this interaction while optimizing the power and...

Adaptive Optics (AO) play an essential role in the field of astronomical seeing for ground-based telescopes, providing a corrected image from the disturbance caused by the light having to travel through the turbulent atmosphere of our Earth. To provide us with more detailed images, the sizes of these telescopes are getting increasingly larger....

This thesis describes the development of the Delft Center for Systems and Control (DCSC) Networked Embedded Robotics Lab (NER) and a novel distributed formation control algorithm to showcase the lab’s experimental capabilities. The lab environment is built to support ground as well as aerial robotic platforms featuring a netted environment and...

Clients and vessel manufacturers are always looking for ways to increase the performance of their fleet. Therefore, a novel modelling strategy for the propulsion plant of naval vessels is explored here. This has been done by using the Linear Parameter Varying (LPV) framework. On one hand, a non-linear description is needed to fully understand...

Experiments in a closed-cycle cryostat suffer from vibrations caused by its pulse tube. To reduce this disturbance, a vibration isolator needs to be placed inside the cryostat. Since mechanical dampers do not work in a cryogenic environment, it requires active damping. This thesis is about the design of a controller for such an active vibration...
