  1. 1. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sara Lenman; Sofia Blaad; [2023]
    Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

  3. 2. Accuracy Improvement and Joint Stiction Relieve in Robot Arms Movement Applying Torque-Based Cartesian Impedance Control With Dithering

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

    Författare :Salvador Monzó Martínez; Altin Zejnullahu; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Robots are nowadays present and essential in a wide range of applications, and robot arms in particular are capable of performing various tasks such as inspection, material handling, and welding. They can be classified into several types, depending on their structure and purpose. LÄS MER

  4. 3. Modeling and Simulation of a Planar Unmanned Aerial Manipulator

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Brynja Þorsteinsdóttir; [2023]
    Nyckelord :Unmanned Aerial Manipulator; Cable Driven Parallel Manipulator; Unmanned Aerial Vehicle; Dynamics; Simulation; Obemannad Flygande Manipulator; Kabeldriven Parallellmanipulator; Obemannad Flygande Farkost; Dynamik; Simulering.;

    Sammanfattning : A unique Unmanned Aerial Manipulator (UAM), also termed an aerial robot, is the subject of this thesis. A UAM is composed of a floating base attached to a manipulator that enables it to interact physically with the environment. LÄS MER

  5. 4. Safety-Critical Teleoperation with Time-Varying Delays : MPC-CBF-based approaches for obstacle avoidance

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Riccardo Periotto; [2023]
    Nyckelord :Robust Control Barrier Functions RCBFs ; Model Predictive Control MPC ; Obstacle Avoidance; Time-Varying Delays; Teleoperation; Robust Control Barrier Functions RCBFs ; Model Predictive Control MPC ; Obstacle Avoidance; Time-Varying Delays; Teleoperation;

    Sammanfattning : The thesis focuses on the design of a control strategy for safety-critical remote teleoperation. The main goal is to make the controlled system track the desired velocity specified by a human operator while avoiding obstacles despite communication delays. LÄS MER

  7. 5. The Impact of Stock Market Manipulation: An empirical study of Nasdaq Stockholm Stock Exchange during 2018-2023

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Alina Mannonen; Caroline Zheng; [2023]
    Nyckelord :Stock Manipulation; Market Efficiency; Market Quality; Stockholm stock exchange; Market microstructure;

    Sammanfattning : Despite widespread concern about market manipulation, there is a general lack of empirical evidence in the literature to support this claim. In particular, market manipulation has not been thoroughly investigated in advanced stock markets. LÄS MER
