  1. 1. Analysis of Some Methods for Identifying Dynamic Errors-in-variables Systems

    Author : Mei Hong; Torsten Söderström; Magnus Jansson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; errors-in-variables; least squares; instrumental variable; maximum likelihood; bias compensated least squares; bias eliminating least squares; Frisch scheme; higher-order statistics; accuracy analysis; periodic data; Signal processing; Signalbehandling;

    Abstract : A system where errors or noises are present on both the inputs and the outputs is called an errors-in-variables (EIV) system. EIV systems appear in industrial and agricultural processes, medical sciences, economical systems, biotechnology, as well as in many other areas. READ MORE

  2. 2. Identification of dynamic errors-in-variables models

    Author : Kaushik Mahata; Torsten Söderström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Abstract : The problem of identifying dynamic errors-in-variables models is of fundamental interest in many areas like process control, array signal processing, astronomical data reduction. In recent years, this field has received increased attention of the research community. READ MORE

  3. 3. A covariance structure analysis approach to the errors-in-variables estimation problem

    Author : David Kreiberg; Fan Yang-Wallentin; Håkan Hjalmarsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; System identification; errors-in-variables models; structural equation modeling; confirmatory factor analysis; minimum distance estimator; separable nonlinear least squares; Statistics; Statistik;

    Abstract : It is a well-known fact that standard regression techniques, when applied to errors-in-variables (EIV) models, lead to biased and inconsistent parameter estimation. The work presented in this thesis address the EIV estimation problem using covariance structure analysis (CSA). READ MORE

  4. 4. On two methods for identifying dynamic errors-in-variables systems

    Author : Mei Hong; Torsten Söderström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Abstract : Identification of dynamic errors-in-variables systems, where both inputs and outputs are affected by errors (measurement noises), is a fundamental problem of great interest in many areas, such as process control, econometrics, astronomical data reduction, image processing, etc. This field has received increased attention within several decades.

  5. 5. Modeling and Control of Bilinear Systems : Application to the Activated Sludge Process

    Author : Mats Ekman; Bengt Carlsson; Claes Breitholtz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bilinear systems; modeling; optimal control; parameter estimation; errors-in-variables; activated sludge process; Automatic control; Reglerteknik;

    Abstract : This thesis concerns modeling and control of bilinear systems (BLS). BLS are linear but not jointly linear in state and control. In the first part of the thesis, a background to BLS and their applications to modeling and control is given. READ MORE
