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...

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...

Renewable energy is becoming more and more important in today's society. Wind energy plays an important role in the production of renewable energy. Due to economic advantages, wind turbines are often sited close together, creating wind farms. As a result, the wind turbines in the farm become interconnected due to the wakes of the turbines. In...

The simulation of aircraft roll rates causes noticeable false g-tilt cues as a result of the simulator cabin roll angle. Although false tilt can be counteracted by swaying the simulator cabin, an improper implementation of the motion drive logic for coordinating sway could cause delayed side-forces. The aim of this paper is to evaluate two...

With the current view on sustainability and global warming, renewable energy sources are becoming more and more important. One of these environmental friendly energy sources is wind energy. To make the price of wind energy more competitive compared to other energy sources, the current trend in the industry is to increase the rotor diameter of...

Smart Thermal Grids (STGs) represent a new concept in the energy sector that involves the use of the smart grid concept in thermal energy networks connecting users, such as households, buildings and greenhouses, to each other via a transport line of thermal energy. In this concept, there exists an energy management system that aims to improve...

The goal of this thesis is to develop online model-based parameter estimation techniques for robotics towards extracting geometrical or physical properties of an unknown (or partially unknown) dynamic environment through a tactile interaction with it. The thesis focuses on a one-dimensional case of a rigid movable object, not yet studied in the...

Networked control systems (NCSs) are control systems in which the control loops are closed through a communication network. These systems usually consist of sensors, actuators, controllers and communication devices. The disruption of these control systems can have a significant impact on public health, safety and lead to large economic losses, e...

When tasks need to be performed in remote, potentially inaccessible and/or hostile environments for humans, it is often more convenient to send a robot. Such environments are often only partially known, and therefore not suitable for fully autonomous robots to operate in. In these situations teleoperation can be used, which combines the problem...

The natural frequency of wind turbine towers can be more than 10% off from the designed frequency. This frequency is important for control because it sets bandwidth limits to some of the control loops. Improving the model will result in better control and load reduction that will in turn contribute to the decrease of the cost of wind energy. The...

Rapid and substantial voltage changes can occur in distribution networks with a high pen- etration of photovoltaic (PV) systems, due to their unpredictable nature. Electronic power inverters are capable of delivering fast reactive power support to maintain customer voltages within operating tolerances and reduce system losses in distribution...

The steady increase in volume of goods to be transported over land and water has necessitated the development of efficient and alternative methods of transportation. In current practices considerable amount of transportation delay is caused due to switching between different modes of transportation resulting in economic losses. Another...

Magnetic levitation actuation has proven to be a viable solution in many applications where high performance actuators are needed that can achieve fine manipulation and position control. Advantages of magnetic levitation include elimination of friction, backlash, vibrations and wear of components due to contact. Many such systems have been...

The use of telepresence becomes an alternative in scenarios such as deep sea maneuvers, inspection and maintenance in hazardous environments or aerial surveillance tasks, amongst some other robotic tasks. In some of these cases, human deployment might be dangerous, expensive and even not possible yet. Because of the wide variety and increasing...

ASML is always searching for improvements in reducing the servo error of both the Wafer Stage and the Reticle Stage of their lithography machines. Due to the repetitive motion and corresponding repetitive servo error of the Reticle Stage Short Stroke (RSSS), Iterative Learning Control (ILC) can be a powerful method to further reduce the servo...

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...

The dynamics of many physical processes can be described by port-Hamiltonian (PH) models where the importance of the energy function can be seen. In Control by Interconnection (CbI), the controller is another PH system that is connected to the plant through a power preserving interconnection to add up the energy functions. However, a major issue...

The development of sustainable energy production methods is an important aspect in lowering the emission of greenhouse gases and exhaustion of fossil fuels. Wind energy is recognized globally as one of the most promising sustainable forms of electricity generation, but the cost of offshore wind energy does not meet the level of fossil-based...
