  1. 11. Design of Gyro Based Roll-Stabilization Controller for a Concept Amphibious Commuter Vehicle

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Ioannis Karagiannis; [2015]
    Nyckelord :Gyroscopic stabilization; roll stabilizer; LQG; Glover-McFarlane;

    Sammanfattning : In this master thesis the gyroscopic stabilization of a two-wheeled amphibious concept vehicle is investigated. The key idea is to neutralize external torques applied on the vehicle by the counter torque produced from the two gyroscopes attached on the vehicle. Here the gyroscopes are used as actuators, not as sensors. LÄS MER

  3. 12. Simulation and Control of Submarines

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Erik Lind; Magnus Meijer; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : When designing control systems for real applications, it is important to first do testing in a simulated environment, to ensure adequate performance. This is especially important when designing control systems for applications that have high operation costs, e.g., submarines, since late errors in the development can be extremely costly. LÄS MER

  4. 13. Optimization and control of feed and transfer pumps

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Carlos Jorques Moreno; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A new low pressure fuel system implementation for Scania’s trucks is being investigated. The main challenge consists in exchanging the mechanical pump with electrical pumps. The electrical pumps must then be controlled to supply exactly the demanded amount of fuel at the required pressure. LÄS MER

  5. 14. Modelling and control of large wind turbine

    Master-uppsats, Avdelningen för fysik och elektroteknik

    Författare :syed hammad zafar; [2013]
    Nyckelord :;

    Sammanfattning : In order to make the wind energy an economical alternative for energy production, upscaling of turbine to 10 - 15MW may be necessary to reduce the overall cost of energy production. This production target requires a considerable increase in the turbine size and placing the turbines at high wind speed locations. LÄS MER

  7. 15. LQG-control of a Vertical Axis Wind Turbine with Focus on Torsional Vibrations

    Uppsats för yrkesexamina på avancerad nivå, Avdelningen för systemteknik

    Författare :Adam Alverbäck; [2012]
    Nyckelord :LQG-control; Vertical axis wind turbine; torsional oscillations;

    Sammanfattning : In this thesis it has been investigated if LQG control could be used to mitigate torsional oscillations in a variable speed, fixed pitch wind turbine. The wind turbine is a vertical axis wind turbine with a 40 m tall axis that is connected to a generator. LÄS MER
