A better understanding of time-varying multimodal human operator control behaviour is required for the development of advanced adaptive control support systems for cases when vehicle dynamics suddenly change, e.g., a stability augmentation system failure. For this research, an approach based on recursive autoregressive exogenous (ARX) models is...

In the past decade, the wind energy subsidies provided by the Dutch government is declining. In order to adopt wind energy as a well-established source of renewable energy, the costs of (offshore) wind energy should be lowered. This can be achieved by increasing the energy production or by lowering the maintenance and initial costs. In search of...

Fixed-time control and vehicle-actuated control are two main signaling strategies implemented at intersections for urban traffic management. The timing and structure of the controllers are usually designed optimally based on average historical demand patterns at the intersection. Under the premise of performance quality assurance, both fixed...

Classical feedback control for floating offshore wind turbines has limited capabilities to reduce wave disturbances. Feedforward control uses disturbance measurement, to construct an additional control law such that the disturbance is attenuated. The main objective of this work is to prove the concept of wave-FF control to attenuate wave...

With climate change increasing its mark on all aspects of the hydrological cycle, societies all over the world living in flood-prone areas are increasingly exposed to flood hazards. In many parts of the world, especially in less developed areas, societies lack knowledge and data to predict future flood events. By predicting a future flood event,...

Deprecation in Java is a language feature that allows API producers to mark program elements as obsolete. However, previous work has identified that this mechanism is co-opted to indicate another concept entirely: a misuse of deprecation. This leaves room for improvement because deprecation warning mechanisms do not fully describe the true...

The arrival of highly automated vehicles introduces a new interaction between the vehicle and driver. System limitations during highly automated driving require the driver to be ready to take back control at request.<br/>Previous studies on the take-over process concluded that the driver requires a transition period to stabilize vehicle control...

With the increasing amount of information sent in control systems, data is more often communicated through a communication network. These networked control systems use the network to exchange control and feedback signals among the system’s components. Data sent over a network attracts adversaries that try to read and modify this data. These...

The primary objective of this work is to research and develop a dynamic model and an advanced control strategy for a reversible solid oxide fuel cell in a grid to ensure load tracking whilst maintaining fuel utilisation and temperature dynamics within a safe range. This report presents the successful development of the dynamic model and...

The propellantless nature of solar-sail propulsion allows researchers to design completely new sets of orbits unreachable or not-maintainable by means of conventional propulsion. The advantage of this somewhat new type of low-thrust propulsion system becomes more evident for long-duration missions where chemical or electrical rocket engines...

Interacting with holograms is something which is widely speculated about. Combining holographic projections with haptic feedback and gesture control might bring this concept closer to reality. This project aims at exploring the possibilities of combining these three technologies into a combined virtual control system. Project owner Safran...

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 &amp; LMN) inthe central and peripheral nervous system. Symptomatic...

Transfer Path Analysis methods allow to describe the propagation of vibrations from an active source to a passive receiving structure. These methods are based in the experimental modelling domain, where the dynamics of the problem are described based on empirical observations from an experiment, as opposed to a numerical model based on natural...

Reinforcement Learning (RL) focuses on maximizing the returns (discounted rewards) throughout the episodes, one of the main challenges when using it is that it is inadequate for safety-critical tasks due to the possibility of transitioning into critical states while exploring. Safe Reinforcement Learning (SafeRL) is a subset of RL that focuses...

Tele-impedance augments classical teleoperation by enabling the human operator to actively command remote robot stiffness. Hereby, an essential strategy used by humans to successfully interact with the unstructured environment complements remote robot-environment interaction. However, literature lacks awareness of benefits and disbenefits of...

Reinforcement learning is used as a type of adaptive flight control. Adaptive Critic Design (ACD) is a popular approach for online reinforcement learning control due to its explicit generalization of the policy evaluation and the policy improvement elements. A variant of ACD, Incremental Dual Heuristic Programming (IDHP) has previously been...

Experimental data were obtained from riding a steer-by-wire bicycle on the open road while perturbing balance with impulsive forces at the seat post (lateral pertubations) as well as perturbing balance with impulsive torques at the steering assembly (steering pertubations). The experiments were conducted at 2.6–5.6 m/s covering both the stable...

Due to the rapid growth of air traffic and the corresponding increase in demanded landing capacity of airports, much research has been done on arrival scheduling and approach trajectory optimization aiming to not only maximize the effective runway throughput of an airports runway system but also significantly reduce fuel consumption.

In this work we consider the problem of cooperative formation control between heterogeneous agents when time-varying delays and/or packet loss are present. Specifically, we introduce a control law for nonlinear fully actuated mechanical agents that separates the cooperative coordinates from the local coordinates, which removes the necessity for...
