  1. 6. Fundamental Control Performance Limitations for Interarea Oscillation Damping and Frequency Stability

    Författare :Joakim Björk; Karl H. Johansson; Lennart Harnefors; Joe H. Chow; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system control; HVDC transmission control; interarea oscillations; power oscillation damping; small-signal stability; fundamental control limitations; frequency stability; hydro power; wind power; non-minimum phase; zero dynamics; eigenvalue analysis; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : With the transition towards renewable energy and the deregulation of the electricity markets, the power system is changing. Growing electricity demand and more intermittent power production increase the need for transfer capacity. Lower inertia levels due to a higher share of renewables increase the need for fast frequency reserves (FFR). LÄS MER

  3. 7. Infants in Control : Prospective Motor Control and Executive Functions in Action Development

    Författare :Janna Gottwald; Gustaf Gredebäck; Claes von Hofsten; Daniela Corbetta; Uppsala universitet; []
    Nyckelord :infant development; action development; prospective motor control; executive functions; action planning; motor development; motion tracking; embodied cognition; developmental psychology; Psychology; Psykologi;

    Sammanfattning : This thesis assesses the link between action and cognition early in development. Thus the notion of an embodied cognition is investigated by tying together two levels of action control in the context of reaching in infancy: prospective motor control and executive functions.

  4. 8. Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

    Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER

  5. 9. State-based Channel Access for a Network of Control Systems

    Författare :Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Joao Hespanha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; multiple access; event-based; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Wireless networked control systems use shared wireless links to communicate between sensors and controllers, and require a channel access policy to arbitrate access to the links. Existing multiple access protocols perform this role in an agnostic manner, by remaining insular to the applications that run over the network. LÄS MER

  7. 10. Cooperative Multi-Vehicle Circumnavigation and Tracking of a Mobile Target

    Författare :Joana Filipa Gouveia Fonseca; Karl Johansson; Yongcan Cao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circumnavigation; target tracking; multi-vehicles; control; estimaion; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A multi-vehicle system is composed of interconnected vehicles coordinated to complete a certain task. When controlling such systems, the aim is to obtain a coordinated behaviour through local interactions among vehicles and the surrounding environment. LÄS MER
