    Sammanfattning : Modular battery systems based on multilevel inverter (MLI) topologies can possibly overcome some shortcomings of two-level inverters when used for vehicle propulsion. The results presented in this thesis aim to point out the advantages and disadvantages, as well as the technical challenges, of modular vehicle battery systems based on MLIs in comparison to a conventional, two-level IGBT inverter drivetrain.

  4. 18. Adapting Grafchart for Industrial Automation

    Författare :Alfred Theorin; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grafchart; JGrafchart; Graphical languages; Language Extension; Attribute Grammars; JastAdd; Flexible manufacturing systems; Agile manufacturing; SOA; DPWS; Web Services;

    Sammanfattning : Current trends in industrial automation are the need for customizable production, vertical integration, more advanced sensors and actuators, and shorter time to market. The currently used control systems and languages for control were developed with a more static production in mind. LÄS MER

  5. 19. Behavioral and Structural Model Based Approaches to Discrete Diagnosis

    Författare :Magnus Larsson; Lennart Ljung; Inger Klein; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The basic motivation for this thesis is the fact that things go wrong. With the growing complexity of todays engineering systems, the need has arisen for systematic approaches to failure diagnosis, i.e., fault detection and isolation. LÄS MER

  7. 20. Modeling and Diagnosis of Friction and Wear in Industrial Robots

    Författare :André Carvalho Bittencourt; Svante Gunnarsson; Mikael Norrlöf; Andrew Starr; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : High availability and low operational costs are critical for industrial systems. While industrial equipments are designed to endure several years of uninterrupted operation, their behavior and performance will eventually deteriorate over time. LÄS MER
