    Sammanfattning : The stringent regulations on the emissions levels of heavy duty vehicles create a demand for new methods of reducing harmful emissions from the engine. In order to be able to follow these increasingly stricter legislations, complex aftertreatment systems are used. LÄS MER

  4. 23. Adapting sonar systems for monitoring ocean energy technologies

    Författare :Francisco Francisco; Jan Sundberg; Mats Leijon; William Megill; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ocean energy; sonar systems; monitoring technologies; marine environment; wave power; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The global energy sector is under profound reforms aiming towards renewable energy sources, clean technologies and expansion of smart grids, all with the additional aim of providing affordable and dependable electricity for everyone. A reduction of carbon dioxide emissions is a priority on the global agenda, and to achieve that, cleaner energy technologies has to be more integrated into the energy mix. LÄS MER

  5. 24. Experiment design with applications in identification for control

    Författare :Henrik Jansson; Håkan Hjalmarsson; Paul von den Hof; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; electronics engineering; electrical engineering; Reglerteknik; Automatic control; Reglerteknik;

    Sammanfattning : The main part of this thesis focuses on optimal experiment design for system identification within the prediction error framework. A rather flexible framework for translating optimal experiment design into tractable convex programs is presented. The design variables are the spectral properties of the external excitations.
