  1. 21. Frequency Domain Identification of Continuous-Time Systems : Reconstruction and Robustness

    Författare :Jonas Gillberg; Lennart Ljung; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete-time domain; Frequency-domain identification; Signal processing; Frequency-domain; Automatic control; Reglerteknik;

    Sammanfattning : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. LÄS MER

  3. 22. A Structure Utilizing Inexact : Primal-Dual Interior-Point Method for Analysis of Linear Differential Inclusions

    Författare :Janne Harju Johansson; Anders Hansson; Ulf Jönsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Optimization; systems theory; Automatic control; Reglerteknik;

    Sammanfattning : The ability to analyze system properties for large scale systems is an important part of modern engineering. Although computer power increases constantly, there is still need to develop tailored methods that are able to handle large scale systems, since sometimes standard methods cannot handle the large scale problems that occur.

  4. 23. Fundamental Estimation and Detection Limits in Linear Non-Gaussian Systems

    Författare :Gustaf Hendeby; Fredrik Gustafsson; Niclas Bergman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; Detection; Linear systems; Non-Gaussian; Limits; GLR; CRLB; Automatic control; Reglerteknik;

    Sammanfattning : Many methods used for estimation and detection consider only the mean and variance of the involved noise instead of the full noise descriptions. One reason for this is that the mathematics is often considerably simplified this way. LÄS MER

  5. 24. Performance and Implementation Aspects of Nonlinear Filtering

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

    Sammanfattning : 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. LÄS MER

  7. 25. Pose Estimation and Calibration Algorithms for Vision and Inertial Sensors

    Författare :Jeroen Diederik Hol; Fredrik Gustafsson; Thomas Schön; Patric Jensfelt; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pose estimation; Sensor fusion; Computer vision; Inertial navigation; Calibration; Automatic control; Reglerteknik;

    Sammanfattning : This thesis deals with estimating position and orientation in real-time, using measurements from vision and inertial sensors. A system has been developed to solve this problem in unprepared environments, assuming that a map or scene model is available. LÄS MER
