  1. 1. Multivariable Frequency-Domain Identification of Industrial Robots

    Författare :Erik Wernholt; Svante Gunnarsson; Jan Swevers; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency-domain identification; industrial robots; nonparametric identification; nonlinear gray-box identification; multivariable systems; closed-loop identification; Automatic control; Reglerteknik;

    Sammanfattning : Industrirobotar är idag en väsentlig del i tillverkningsindustrin där de bland annat används för att minska kostnader, öka produktivitet och kvalitet och ersätta människor i farliga eller slitsamma uppgifter. Höga krav på noggrannhet och snabbhet hos robotens rörelser innebär också höga krav på de matematiska modeller som ligger till grund för robotens styrsystem. LÄS MER

  3. 2. Viscoelastic Materials : Identification and Experiment Design

    Författare :Agnes Rensfelt; Torsten Söderström; Händel Peter; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viscoelastic materials; complex modulus; system identification; optimal experiment design; distributed parameter systems; frequency domain identification; wave propagation; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Viscoelastic materials can today be found in a wide range of practical applications. In order to make efficient use of these materials in construction, it is of importance to know how they behave when subjected to dynamic load. LÄS MER

  5. 4. Structural Reformulations in System Identification

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

    Sammanfattning : 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. LÄS MER

  7. 5. Closed-loop Identification : Methods, Theory, and Applications

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

    Sammanfattning : System identification deals with constructing mathematical models of dynamical systems from measured data. Such models have important applications in many technical and nontechnical areas, such as diagnosis, simulation, prediction, and control. LÄS MER
