Full Automation of Air Traffic Management in High Complexity Airspace / Vollautomatisierung der Flugsicherung in Lufträumen hoher KomplexitätEhrmanntraut, Rüdiger 20 May 2010 (has links) (PDF)
The thesis is that automation of en-route Air Traffic Management in high complexity airspace can be achieved with a combination of automated tactic planning in a look-ahead time horizon of up to two hours complemented with automated tactic conflict resolution functions. The literature review reveals that no significant results have yet been obtained and that full automation could be approached with a complementary integration of automated tactic resolutions AND planning. The focus shifts to ‘planning for capacity’ and ‘planning for resolution’ and also – but not only – for ‘resolution’.
The work encompasses a theoretical part on planning, and several small scale studies of empirical, mathematical or simulated nature.
The theoretical part of the thesis on planning under uncertainties attempts to conceive a theoretical model which abstracts specificities of planning in Air Traffic Management into a generic planning model. The resulting abstract model treats entities like the planner, the strategy, the plan and the actions, always considering the impact of uncertainties. The work innovates in specifying many links from the theory to the application in planning of air traffic management, and especially the new fields of tactical capacity management.
The second main part of the thesis comprises smaller self-containing works on different aspects of the concept grouped into a section on complexity, another on tactic planning actions, and the last on planners. The produced studies are about empirical measures of conflicts and conflict densities to get a better understanding of the complexity of air traffic; studies on traffic organisation using tactical manoeuvres like speed control, lateral offset and tactical direct using fast time simulation; and studies on airspace design like sector optimisation, dynamic sectorisation and its optimisation using optimisation techniques.
In conclusion it is believed that this work will contribute to further automation attempts especially by its innovative focus which is on planning, base on a theory of planning, and its findings already influence newer developments.

Compact Multi-Coil Inductive Power Transfer System with a Dynamic Receiver Position EstimationBouattour, Ghada 07 April 2022 (has links)
Inductive power transfer (IPT) systems with tolerance to the lateral misalignment are
advantageous for enhancing the transmitted power, usability and security of the system. In this
thesis, a misalignment tolerant multi-coil design is proposed to supply stationary and dynamic
battery-free wireless devices. A compact architecture composed of individually switchable 3
layers of printed coils arranged with overlap for excellent surface coverage. A hybrid architecture
based on three compact AC supply modules reduces the supply circuit complexity on the sending
Seite 2 von 4side. It detects the position of the receiver coil quickly, controls the activation of the transmitting
coils and estimates the next receiver position. The proposed architecture reduces the circuit
footprint by a factor of 62% compared to common architectures.
A transmitter coil activation strategy is proposed based on the detection of the transmitting coils
voltage and communication between sending side and receiving side to detect devices to supply
nature and position and to differentiate them from other conductive objects in the sending area
to the supplying security. The experimental results prove that the proposed architecture has a
good performance for different trajectories when the device speed does not exceed 15 mm/s.
Besides, the maximum detection time for the initial device position is about 1.6 s. The maximal
time interval to check the transmitter coils is around 0.7 s.:1. INTRODUCTION

7. CONCLUSION AND OUTLOOK / Induktive Energieübertragungssysteme (IPT) mit Toleranz gegenüber seitlichem Versatz sind
vorteilhaft, um die übertragene Leistung, die Nutzbarkeit und die Sicherheit des Systems zu
verbessern. In dieser Arbeit wird ein versatztolerantes Multispulen-Design vorgeschlagen, um
stationäre und dynamische batterielose drahtlose Geräte zu versorgen. Die kompakte Architektur
besteht aus 3 einzeln schaltbaren Schichten gedruckter Spulen, die überlappend angeordnet sind,
um eine hervorragende Oberflächenabdeckung zu gewährleisten. Eine hybride Architektur, die auf
drei kompakten AC-Versorgungsmodulen basiert, reduziert die Komplexität der
Versorgungsschaltung auf der Senderseite. Sie erkennt die Position der Empfängerspule schnell,
steuert die Aktivierung der Sendespulen und schätzt die nächste Empfängerposition. Die
vorgeschlagene Architektur reduziert den Platzbedarf der Schaltung um einen Faktor von 62 % im
Vergleich zu herkömmlichen Architekturen.
Es wird eine Aktivierungsstrategie für die Sendespulen vorgeschlagen, die auf der Erkennung der
Spannung der Sendespulen und der Kommunikation zwischen Sende- und Empfangsseite basiert,
um die Art und Position der zu versorgenden Geräte zu erkennen und sie von anderen leitfähigen
Objekten im Sendebereich zu unterscheiden. Die experimentellen Ergebnisse zeigen, dass die
vorgeschlagene Architektur eine gute Leistung für verschiedene Trajektorien hat, wenn die
Geschwindigkeit der Geräte 15 mm/s nicht überschreitet. Außerdem beträgt die maximale
Erkennungszeit für die anfängliche Geräteposition etwa 1,6 s. Das maximale Zeitintervall für die
Überprüfung der Senderspulen beträgt etwa 0,7 s.:1. INTRODUCTION
