  1. 1. Quaternionic Analysis

    University essay from Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Author : Mitra Fathian Pourkondori; [2022]
    Keywords : Quaternion;

    Abstract : In this thesis, we study Quaternionic Analysis, which is the most natural and close generalization of complex analysis. Quaternion Analysis conserves many of its important features by key reference A. Sudbery. READ MORE

  2. 2. Space Rider System: GNC and System Model Improvements

    University essay from KTH/Rymdteknik

    Author : Simon Vial; [2022]
    Keywords : Space Rider System; Disturbance Modelling; Maneuver Optimization; Space Rider System; Modellering av Störningar; Manöveroptimering;

    Abstract : As part of a continuous trend of the space sector for obtaining higher performance space science and Earth observations, there is an increasing demand for higher requirements in pointing accuracy and disturbance prediction. The Space Rider System (SRS) is a Low Earth Orbit (LEO) reusable vehicle that aims at answering to that demand. READ MORE

  3. 3. Robust control system development forVTOL-to-fixed wing flight transition withthe EcoSoar UAV : A masters thesis in Automatic Control

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Robert Hedman; [2020]
    Keywords : drone; UAV; thesis; automatic; control; VTOL;

    Abstract : A non switching, non linear, quaternion based attitude P2 controller, together with a sensitivitynormalizing function for the control surfaces has been simulated and implemented on a flying fixedwing with non vectored engines. In simulations the controller worked well in all flight modes,hovering, transition and flying, and also rejected a simple wind disturbance in all modes. READ MORE

  4. 4. Orientation estimation and movement recognition using low cost sensors

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Álvaro López Revuelta; [2017]
    Keywords : signal processing; orientation estimation; quaternion; euler angles; rotation matrices;

    Abstract : Orientation estimation is a very well known topic in many fields such as in aerospace or robotics. However, the sensors used are usually very ex- pensive, heavy and big, which make them not suitable for IoT (Internet of Things) based applications. READ MORE

  5. 5. Attitude Navigation using a Sigma-Point Kalman Filter in an Error State Formulation

    University essay from KTH/Rymd- och plasmafysik

    Author : Periklis-Konstantinos Diamantidis; [2017]
    Keywords : unscented Kalman filtering; information ltering; quaternions; attitude navigation; gyroscope modelling; error state formulation; sensor fusion;

    Abstract : Kalman filtering is a well-established method for fusing sensor data in order to accuratelyestimate unknown variables. Recently, the unscented Kalman filter (UKF) has beenused due to its ability to propagate the first and second moments of the probability distribution of an estimated state through a non-linear transformation.
