  2. 1. Attitude and Trajectory Estimation for Small Suborbital Payloads

    Author : Yunxia Yuan; Nickolay Ivchenko; Gunnar Tibert; Rafael Wisnewski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free falling; least squares optimization; unscented Kalman filter; Flyg- och rymdteknik; Aerospace Engineering;

    Abstract : Sounding rockets and small suborbital payloads provide a means for research in situ of the atmosphere and ionosphere. The trajectory and the attitude of the payload are critical for the evaluation of the scientific measurements and experiments. READ MORE

  4. 2. Kalman Filters for Nonlinear Systems and Heavy-Tailed Noise

    Author : Michael Roth; Fredrik Gustafsson; Simo Särkkä; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis is on filtering in state space models. First, we examine approximate Kalman filters for nonlinear systems, where the optimal Bayesian filtering recursions cannot be solved exactly. These algorithms rely on the computation of certain expected values. READ MORE

  5. 3. Performance and Implementation Aspects of Nonlinear Filtering

    Author : Gustaf Hendeby; Fredrik Gustafsson; Petar Djurić; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; nonlinear filtering; fault detection; Cramer-Rao lower bound; Kullback divergence; intrinsic accuracy; Automatic control; Reglerteknik;

    Abstract : I många fall är det viktigt att kunna få ut så mycket och så bra information som möjligt ur tillgängliga mätningar. Att utvinna information om till exempel position och hastighet hos ett flygplan kallas för filtrering. I det här fallet är positionen och hastigheten exempel på tillstånd hos flygplanet, som i sin tur är ett system. READ MORE

  6. 4. Terrain navigation for underwater vehicles

    Author : Ingemar Nygren; Magnus Jansson; Stephen Rock; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Abstract : In this thesis a terrain positioning method for underwater vehicles called the correlation method is presented. Using the method the vehicle can determine its absolute position with the help of a sonar and a map of the bottom topography. READ MORE

  7. 5. Localization for Autonomous Vehicles in Underground Mines

    Author : Kristin Nielsen; Gustaf Hendeby; Fredrik Gustafsson; Robert Lundh; Giorgio Grisetti; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The trend of automation in industry, and in the society in general, is something that probably all of us have noticed. The mining industry is no exception to this trend, and there exists a vision of having completely automated mines with all processes monitored and controlled through a higher level optimization goal.
