1. Multivariable Frequency-Domain Identification of Industrial Robots
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
2. Viscoelastic Materials : Identification and Experiment Design
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
3. On the Identification and Approximation of Linear Systems
Sammanfattning : This thesis consists of four parts. In the first one, the connections between system identification and model reduction are discussed. The second part deals with the problem of estimating ARMA models for narrow band processes. LÄS MER
4. On-Line Structure Selection for the Identification of Multivariable Systems
Sammanfattning : An algorithm is described for the selection of mod el structure for identifying multivariable mode Is of"black box" character. The algorithm receives as "input" a mode I in a given parametrization (= mode I structure). It is then tested whether this parametrization is suitable (well conditioned) for identification purposes.

5. Identification of Viscoelastic Materials by Use of Wave Propagation Methods
Sammanfattning : Complex moduli and Poisson’s ratio have been estimated using extensional and torsional wave experiments. The data were used for assessment of linearity and isotropy of two polymers, polymethyl methacrylate (PMMA) and polypropylene (PP). The responses of both materials were found to be close to linear and isotropic. LÄS MER
