    Sammanfattning : För vindkraftverk i mindre skala används i huvudsak två sätt att avlasta vid höga vindhastigheter, stallreglering och girning ur vind. En tredje metod är att pitcha rotorbladet till en mindre attackvinkel. Då minskar belastningen på rotorbladet samtidigt som effektgenerering kan bibehållas. LÄS MER

  2. 2. Electronic Control Unit for Automatic Control of Torque Vectoring

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :John Huzell; Johan Göransson; [2020]
    Nyckelord :torque vectoring; electronic control unit; automatic control; yaw moment; CAN; PCB; Formula Student; Technology and Engineering;

    Sammanfattning : Torque vectoring for automobiles is used to increase cornering speeds and improve road safety by manipulating the car's wheel-speeds. One method of torque vectoring for a rear-wheel-drive Formula Student race car is using a dual-clutch to slip the inner wheel thus create a yaw moment during cornering. LÄS MER

  3. 3. Robust post impact vehicle motion control using torque vectoring

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Nikhil Jain; [2019]
    Nyckelord :;

    Sammanfattning : Several statistical studies have suggested that the risk of injury is significantly higher in multiple event accidents (MEAs) than in single event crashes. Improper driving in such scenarios leads to hazardous vehicle heading angles and excessive lateral deviations from thevehicle path, resulting in severe secondary crashes. LÄS MER

  4. 4. Energy efficient cornering : Simulation and verification

    Master-uppsats, KTH/Fordonsdynamik; KTH/Fordonsdynamik

    Författare :Nicolas Luco; Keren Zhu; [2018]
    Nyckelord :Bicycle model; Energy consumption; Vehicle cornering behaviour; Yaw moment control;

    Sammanfattning : The purpose of this master thesis is to study the energy efficiency of a vehicle when it is cornering. To achieve this, a Simulink model was built from a simple basic bicycle model and theoretically validated. This model was then analysed and successively improved by adding velocity and yaw moment control. LÄS MER

  5. 5. Estimation of Ship Properties for Energy Efficient Automation

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Lucas Nilsson; [2016]
    Nyckelord :System identification; ship properties; energy efficient; automation; ship modelling; estimation; signal processing; simulation; ship dynamics; cusum; cumulative summation; change in dynamics; load condition; podded propulsion; azipod; yaw dynamics; noise impact; measurement noise; model error; bias due to model error; ship yaw model; moment of inertia; estimate ship properties; ship automation;

    Sammanfattning : One method to increase efficiency, robustness and accuracy of automatic control, is to introduce mathematical models of the system in question to increase performance. With these models, it is possible to predict the behavior of the system, which enables control according to the predictions. LÄS MER
