1. 6. Handling demand-capacity imbalances in aerial vehicle traffic

   Författare :Leonid Sedov; Tobias Andersson Granberg; Valentin Polishchuk; Joost Ellerbroek; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : It is expected that the number of drones used in both commercial and leisure operations will grow significantly in the coming years, which raises the need for a solid framework for management of this traffic. Unmanned traffic management (UTM) is a system for handling autonomous drone flights over urban areas. LÄS MER

   Sammanfattning : In the process of designing an electric power supply system for an aircraft, parameters like low weight and low losses are important. Reliability, robustness and low cost are other important factors. LÄS MER

4. 8. Aircraft Vehicle Systems Modeling and Simulation under Uncertainty

   Författare :Sören Steinkellner; Petter Krus; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : In aircraft development, it is crucial to understand and evaluate behavior, performance, safety and other aspects of the systems before and after they are physically available for testing. Simulation models are used to gain knowledge in order to make decisions at all development stages. LÄS MER

5. 9. Geometric Control of Thrust Propelled Systems

   Författare :Pedro Miguel Ótão Pereira; Dimos V. Dimarogonas; Jana Tumova; Panagiotis Tsiotras; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear control; geometric control; thrust propelled systems; slung load transportation; aerial tethered transportation; control of aerial vehicles; tracking and stabilization; global stabilization; bounded control; disturbance removal; distributed control; attitude synchronization; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : This thesis was motivated and inspired by the AEROWORKS project, a European research project, whose main goal was to deploy multiple heterogeneous unmanned aerial vehicles in environments where human intervention is restricted.In particular, this thesis focuses on control of aerial vehicles for the purposes of cargo transportation, an application of interest, for example, in inspection and maintenance of aging infrastructures.
