  1. 6. Studies on identification of time-variant and time-varying nonlinear systems

    Författare :Anders Nordsjö; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis addresses same aspects of nonlinear systemidentification. In par ticular, it is assumed that theconsidered systems can be described by the Wiener model whichconsists of a dynamit linear part followed by a nonbnear partor the Haxnmerstein model in which the order of these twoblocks is reversed.

  3. 7. Dynamic Load Models for Power Systems - Estimation of Time-Varying Parameters During Normal Operation

    Författare :Ines Romero; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage stability; Load modeling; modeling and identification; dynamic load models; normalization in reactive load models;

    Sammanfattning : Economic and environmental concerns will slow down the expansion of the transmission system in many countries. The addition of new transmission lines will be few and far between. The de-regulation of the power supply will introduce new power flow patterns on the bulk transmission systems. LÄS MER

  4. 8. On Reverberation Enhancement in Auditoria

    Författare :Peter Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active sound field control; room acoustics; reverberation enhancement; listening tests; subjective effects; sound-reinforcement; feedback systems; feedback control; computer modelling of acoustics in enclosures; modulation; electro acoustics; time-varying filters;

    Sammanfattning : The analysis of electroacoustic systems for reverberation enhancement in auditoria is the topic of this thesis. Such systems have been developed since the 50's and been commercially available since then as well. During the 80's several new system ideas have been presented but there are still some open questions that are addressed here. LÄS MER

  5. 9. Control of Constrained Dynamical Systems with Performance Guarantees: With Application to Vehicle motion Control

    Författare :Ankit Gupta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear matrix inequalities; Robust control; Invariant set; Semi-definite program; Linear parameter varying system; Linear fractional transformation;

    Sammanfattning : In control engineering, models of the system are commonly used for controller design. A standard control design problem consists of steering the given system output (or states) towards a predefined reference. Such a problem can be solved by employing feedback control strategies.

  7. 10. Bayesian Sequential Inference for Dynamic Regression Models

    Författare :Parfait Munezero; Mattias Villani; Helga Wagner; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bayesian sequential inference; Dynamic regression models; Particle filter; Online prediction; Particle smoothing; Linear Bayes; Statistics; statistik;

    Sammanfattning : Many processes evolve over time and statistical models need to be adaptive to change. This thesis proposes flexible models and statistical methods for inference about a data generating process that varies over time. The models considered are quite general dynamic predictive models with parameters linked to a set of covariates via link functions. LÄS MER
