  1. 1. Structural Reformulations in System Identification

    Author : Christian Lyzell; Martin Enqvist; Lennart Ljung; Alessandro Chiuso; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Dimension reduction; Subspace identification; Difference algebra;

    Abstract : In system identification, the choice of model structure is important and it is sometimes desirable to use a flexible model structure that is able to approximate a wide range of systems. One such model structure is the Wiener class of systems, that is, systems where the input enters a linear time-invariant subsystem followed by a time-invariant nonlinearity. READ MORE

  2. 2. On System Identification and Acoustic Echo Cancellation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Per Åhgren; Peter Stoica; Peter Händel; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic echo cancellation; stereophonic acoustic echo cancellation; doubletalk detection; adaptive beamforming; adaptive filtering; system identification; recursive system identification; loudspeaker impulse response estimation; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Abstract : The topic of acoustic echo cancellation has received a lot of interest over the years. Even though the topic is relatively old, the increasing demand for hands-free telephony has made it more important than ever before. READ MORE

  3. 3. Initialization Methods for System Identification

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Christian Lyzell; Lennart Ljung; Martin Enqvist; Magnus Jansson; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Initialization methods; Regressor selection; Identifiability; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik 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.

  4. 4. On Model Simplification in System Identification

    University dissertation from Linköping : Linköping University

    Author : Bo Wahlberg; [1985]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model simplification; System identification;

    Abstract : This report deals with the connection between system identification and model reduction. We propose an identification algorithm that is based on the least squares identification method and either of the model reduction techniques: Frequency weighted truncated balanced realization or frequency weighted optimal Hankel-norm model reduction.
