  2. 1. Non-parametric methods for functional data

    Author : Johan Strandberg; Sara Sjöstedt de Luna; Konrad Abramowicz; Lina Schelin; Charlotte Häger; Pedro Delicado; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; functional data analysis; testing; clustering; prediction; inference; bagging Voronoi strategy; kriging; dependency; matematisk statistik; Mathematical Statistics;

    Abstract : In this thesis we develop and study non-parametric methods within three major areas of functional data analysis: testing, clustering and prediction. The thesis consists of an introduction to the field, a presentation and discussion of the three areas, and six papers. READ MORE

  4. 2. Initialization Methods for System Identification

    Author : Christian Lyzell; Lennart Ljung; Martin Enqvist; Magnus Jansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Initialization methods; Regressor selection; Identifiability; Automatic control; Reglerteknik;

    Abstract : In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction error.

  5. 3. Non-intrusive Methods for Mode Estimation in Power Systems using Synchrophasors

    Author : Vedran Peric; Luigi Vanfretti; Xavier Bombois; Cristian Rojas; Mani V. Venkatasubramanian; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchrophasors; Phasor measurement units; system identification; mode estimation; electromechanical oscillations; prediction error; signal selection; experiment design; probing; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Real-time monitoring of electromechanical oscillations is of great significance for power system operators; to this aim, software solutions (algorithms) that use synchrophasor measurements have been developed for this purpose. This thesis investigates different approaches for improving mode estimation process by offering new methods and deepening the understanding of different stages in the mode estimation process.

  6. 4. Topological Methods for Motion Prediction and Caging

    Author : Joao Frederico Pinto Basto de Carvalho; Danica Kragic; Frank van der Stappen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; Datalogi;

    Abstract : To fulfill the requirements of automation in unstructured environmentsit will be necessary to endow robots with the ability to plan actions thatcan handle the dynamic nature of changing environments and are robust toperceptual errors. This thesis focuses on the design of algorithms to facilitatemotion planning in human environments and rigid object manipulation. READ MORE

  7. 5. Closed-loop Identification : Methods, Theory, and Applications

    Author : Urban Forssell; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : System identification deals with constructing mathematical models of dynamical systems from measured data. Such models have important applications in many technical and nontechnical areas, such as diagnosis, simulation, prediction, and control. READ MORE
