  1. 21. Modeling and Control of a PMSynRel Drive for a Plug-InHybrid Electric Vehicle

    Författare :Shuang Zhao; Chandur Sadarangani; Sigurd Övrebö; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; feasible region; inductance spatial harmonics; integrated charger; permanent-magnet assisted synchronous reluctance machine; plug-in hybrid-electric vehicle; polarity detection; saturation and cross-saturation; sensorless control; signal injection; transient modeling.;

    Sammanfattning : This thesis presents two transient models for a prototype integrated charger for use in a plug-in hybrid-electrical vehicle application. The models can be useful in order to develop control algorithms for the system or to recommend improvements to the machine design. LÄS MER

  3. 22. Control strategies for various grid conditions in wave energy system

    Författare :Md Imran Ullah; Irina Temiz; Johan Forslund; Cecilia Boström; Deepak Elamalayil Soman; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The imperative goal of reducing carbon emissions and reaching net zero emissions in electricity generation has driven various renewable technologies, including wind energy, solar energy, and wave energy, among others. Even though wave energy is a recent addition to the already existing renewable energy technologies, it offers distinct advantages, such as a high power density and lower inter-annual variability compared to wind energy.

  4. 23. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

    Författare :Tetiana Bogodorova; Luigi Vanfretti; Konstantin Turitsyn; Francisco Gonzalez-Longatt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.

  5. 24. Adaptive control for robots to handle uncertainties, delays and state constraints

    Författare :Viswa Narayanan Sankaranarayanan; George Nikolakopoulos; Sumeet Gajanan Satpute; Christos Verginis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive control; barrier funciton; nonlinear control; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Sammanfattning : The stability and safety of robotic systems are heavily impacted by delays and parametric uncertainties due to external disturbances, modeling inaccuracies, reaction forces, and variations in dynamics. This work addresses the effects of parametric uncertainties in the application of payload transportation by robotic systems that involve time delays and state constraints. LÄS MER

  7. 25. Model-Implemented Fault Injection for Robustness Assessment

    Författare :Rickard Svenningsson; Martin Törngren; Sasikumar Punnekkat; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Injection; Model-Implemented Fault Injection; Robustness; Assessment; ISO 26262; ISO 61508; Software;

    Sammanfattning : The complexity of safety-related embedded computer systems is steadilyincreasing. Besides verifying that such systems implement the correct functionality, it is essential to verify that they also present an acceptable level of robustness. LÄS MER
