  1. 1. Quality Estimation of Approximate Models

    Författare :Fredrik Tjärnström; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis discusses three different topics: model error modeling, bootstrap, and model reduction. These subjects may at first sight seem to be quite far away from each other. However, there are some connections between them, the most importantone being uncertainty estimation.Model error modeling is actually a tool for model validation. LÄS MER

  3. 2. Variance Expressions and Model Reduction in System Identification

    Författare :Fredrik Tjärnström; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Although system identification is now a mature research field, some problems remain unsolved. Examples of unsolved or partly unsolved problems are; accuracy of subspace identification algorithms, identification via model reduction, identification for control, and identification of non-linear systems.
