In recent years, developments in the field of aerospace materials and structures has been bringing major breakthroughs in the construction of air vehicles to be more lightweight yet with higher strength. However, the aircraft body can deform more appreciably due to the occurrence of flow separation and flutter. Therefore, active control is...

Amyotrophic lateral sclerosis (ALS) is themost frequent form of motor neuron diseases (MND). This neurodegenerativedisease progresses relentlessly quick. The characteristic feature of ALS is theconcurrent degeneration of the upper and lower motoneurons (UMN & LMN) inthe central and peripheral nervous system. Symptomatic...

Currently used imaging methods in Atomic Force Microscopy (AFM) including the use of a Lock-In Amplifier or a Phase-Locked Loop, are suboptimal. In this report, the image resolution in AFM is improved by detecting the tip-sample interaction using complete measurements of the input of the cantilever and its measured deflection. Two methods are...

In car driving, manual control to keep a vehicle within its lane is mainly performed based on visual information of the road ahead. Linear models describing behavior in such tasks can therefore be directly based on the human perception of the visual scene, although it is currently unclear how this perception guides control behavior. In...

Recently, Offshore Wind Turbines (OWT) have attracted great attention in an effort to make a shift from fossil-based energy sources towards an enhanced sustainable and renewable energy production. In order to achieve the renewables targets and reduce the cost of wind energy, OWTs are consistently increasing in size. Therefore, research has...

To aid in the continued effort of making unmanned flight safer, this paper presents the experimenting effort towards determining aerodynamic forces on a off-the-shelf quad-rotor under compromised circumstances. For the first time an Incremented Nonlinear Dynamic Inversion controller is used for compromised flight in wind tunnel conditions. For...

Previous years have seen a rise in the use of Unmanned Aerial Vehicles (UAVs). Reaching a large endurance and range while being able to perform Vertical Take-Off and Landing (VTOL) landings allows a broad range of applications. For this purpose the DelftaCopter (DC) was developed, a tilt-body tailsitter UAV. It hovers using a single helicopter...

Joint impedance describes the dynamic resistance of a joint in response to position perturbations. Joint impedance is known to vary nonlinearly during movement caused by varying joint angle and muscle activation. The nonlinear behaviour can be described using linear time-varying models under certain assumption. Recently a number of time-varying...

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 an effort to develop new tools for the classification of neurodegenerative diseases, the effect on the ocular motor system and specifically the visuomotor integration has been a field of interest for more than a decade. Where tracking tasks have shown the potential to quantify fine motor skills of the hand, too little is known about the...

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)...

Ultrasound gives the opportunity to look at muscles and observe their change in length. This tool has increased the knowledge about muscle-tendon dynamics and sometimes revealed surprising muscle stretch behaviour. System identification experiments use robots to disturb the ankle and measure its torque and angle. Muscle movement is derived from...

Half of the long-termed disabled stroke survivors experience increased hyper-resistance of the wrist. Discrimination between the two components of joint hyper-resistance, i.e. the neural reflexive and intrinsic tissue component, is important since the components require a different treatment method. To discriminate between the two components,...

Identifying the time-varying, adapting human operator online could enable adaptive human-machine support systems and attention monitoring for human-in-the-loop vehicle control tasks. A validated, online identification method, including adaptation detection is missing, however.<br/><br/>In this MSc thesis project, online human operator...

A new aviation legislation makes it mandatory for air-carrier pilots to go through stall recovery training on simulators. As a result, new aerodynamic modeling techniques are required to model complex non-linear behavior of the aircraft flight envelope. In 2005, the Multivariate Simplex B-Splines method was developed. MSBS are a true general...

From 2019 onwards, airline pilots will be required to follow stall training in simulators. A major open research question is which level of model fidelity is required for effective training. As part of an effort to answer this question, a stall model of a Cessna Citation II aircraft is developed from specifically-gathered flight test data. The...

Introduction: System identification of the neuromuscular controller that regulates human balance, gives insight in the causes and effects of human balance disorders. The combination of varying perturbation properties in literature and lack of rationale behind chosen perturbation properties, reveals possible violations of assumptions made to...

Sleep is an immensely important biological function and dysregulated sleep can have severe detrimental effects on health and well-being. Over 80 sleep disorders have been classified and of those sleep apnoea is one of the most common, having a prevalence of at least 20 percent in the general population. Sleep apnoea belongs to a family of...

<br/>In recent years the Tapping Mode-Atomic Force Microscope (TM-AFM) has become one of the most important tools for imaging on the nanometer scale. In comparison with other contemporary technologies, the AFMs have been able to obtain atomic resolution both in high vacuum and liquid environments thus affirming their supremacy. The AFM can be...

The effects of horizontal tail geometry and position on longitudinal flapping-wing micro aerial vehicle dynamics were studied using wind tunnel and free-flight experiments. Linearised models were used to analyse the effect on the dynamic properties of the ornithopter. Results show higher steady-state velocity and increased pitch damping for...
