  3. 12. Nonlinear optimization approaches to H2-norm based LPV modelling and control

    Författare :Daniel Petersson; Lennart Ljung; Johan Löfberg; Henrik Sandberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Sammanfattning : To be able to analyze certain classes of non-linear systems, it is necessary to try to represent them as linear parameter varying systems or even as linear fractional representations. For linear parameter varying systems and linear fractional representations of systems there exists many advanced analysis methods such as IQC-analysis and μ-analysis. LÄS MER

  4. 13. On Generation and Recombination in Cu(In,Ga)Se2 Thin-Film Solar Cells

    Författare :Jonas Malmström; Lars Stolt; Uwe Rau; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; solar energy conversion; solar cells; Cu In; Ga Se2; device modelling; optical properties; electron-hole generation; light trapping; electron-hole recombination; Elektronik; Electronics; Elektronik;

    Sammanfattning : The solar cell technology based on Cu(In,Ga)Se2 (CIGS) thin-films provides a promising route to cost competitive solar electricity. The standard device structure is ZnO:Al/ZnO/CdS/CIGS/Mo films on a glass substrate, where the first three layers are n-type semiconductors with wide bandgaps, forming a pn-junction with the p-type CIGS absorber layer; the Mo layer serves as a back contact.

  5. 14. Non-Linear System Identification with Neural Networks

    Författare :Jonas Sjöberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis addresses the non-linear system identification problem, and in particular, investigates the use of neural networks in system identification. An overview of different possible mode! structures is given in a common framework. LÄS MER

  7. 15. Resitive FET Mixers

    Författare :Klas Yhland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents theory, device models and circuits related to resistive FET mixers: A wave analysis for resistive mixers The analysis gives an intuitive estimate of resistive mixer performance when most parameters are unknown. It is based on the assumption that all mixing terms generated in the mixer are terminated with the same impedance. LÄS MER
