1. Data Driven Modeling for Aerodynamic Coefficients
Master-uppsats, KTH/Matematisk statistikSammanfattning : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters.

2. System Identification of a Fixed-Wing UAV Using a Prediction Error Method
Master-uppsats, Linköpings universitet/ReglerteknikSammanfattning : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle. LÄS MER
3. Feedback Linearization for Model Agnostic Aircraft Simulation Control
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : This thesis presents a method, based on feedback linearization, for controlling a general 3-degree-of-freedom simulation model of an aircraft. Only aircraft models that utilize Taylor approximations of the aerodynamic coefficients are considered. LÄS MER
4. Airspeed estimation of aircraft using two different models and nonlinear observers
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. LÄS MER
5. Forced response numerical investigation of a transonic compressor rotor
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. LÄS MER
