  1. 16. Inverse system identification with applications in predistortion

    Författare :Ylva Jung; Martin Enqvist; Lennart Ljung; Torkel Glad; Thomas Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; inverse models; signal processing; power amplifiers; predistortion; communication electronics;

    Sammanfattning : Models are commonly used to simulate events and processes, and can be constructed from measured data using system identification. The common way is to model the system from input to output, but in this thesis we want to obtain the inverse of the system. LÄS MER

  2. 17. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

    Författare :Tetiana Bogodorova; Luigi Vanfretti; Konstantin Turitsyn; Francisco Gonzalez-Longatt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.

  3. 18. On performance analysis of subspace methods in system identification and sensor array processing

    Författare :Magnus Jansson; Bo Wahlberg; Mats Molander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subspace methods; system identification; state-space models; linear regression; sensor array processing; performance analysis; EM algorithm; minimum redundancy array;

    Sammanfattning : This thesis addresses the issue of performance analysis of subspace-based parameter estimation methods in two different applications, namely system identification and sensor array processing.  The objective is to study the quality of the estimated models as the amount of data increases, and to suggest improvements and give user guidelines.
