  1. 1. Model parameter estimation for a handheld nutrunner

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Jonathan Fridstrand; Johanna Sturk; [2020]
    Nyckelord :;

    Sammanfattning : The purpose of this project is to investigate the angled nutrunner, which is a hand held torque tool often used in the industry to tighten bolted joints. The goal is to estimate parameter values for an existing model that can describe the reaction force and the angular displacement of the tool as a function of the torque transferred to the joint.

  3. 2. Modelling and Fault Detection of an Overhead Travelling Crane System

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Ingrid Sjöberg; [2018]
    Nyckelord :Fault detection; modelling; overhead travelling crane; girder crane; model based fault detection;

    Sammanfattning : Hoists and cranes exist in many contexts around the world, often carrying veryheavy loads. The safety for the user and bystanders is of utmost importance. Thisthesis investigates whether it is possible to perform fault detection on a systemlevel, measuring the inputs and outputs of the system without introducing newsensors. LÄS MER

  4. 3. Implementation of Grey-Box Identification in JModelica.org

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

    Författare :Elias Palmkvist; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Grey-box identification is a tool to identify and improve nonlinear system models by estimating parameters. The estimation is done by optimizing a cost function using measurement data. The robustness of the estimations can then be analyzed with statistics. JModelica. LÄS MER

  5. 4. A Study of Quadrotor Modelling

    Master-uppsats, Institutionen för datavetenskap

    Författare :Dag Sonntag; [2011]
    Nyckelord :Quadrotor; System identification; modelling; Greybox model; blackbox model; Neural Network;

    Sammanfattning : Quadrotors are a type of aircraft that lately has gained increased popularity within the UAV-scientific area. Many research groups around the world have implemented control systems that allow for autonomous flight of quadrotors with the help of the known dynamics. This thesis presents two approaches to modelling the dynamics of the quadrotor. LÄS MER

  7. 5. A GUI for online presentation of steel and steelmaking ladle temperature data and simulation.

    Kandidat-uppsats, Elektroteknik

    Författare :Muhammad Faheem; [2009]
    Nyckelord :Ladle; GUI; temperature; model; blackbox; greybox; Matlab;

    Sammanfattning : Continuous casting is a casting process that produces steel slabs in a continuous manner with steel being poured at the top of the caster and a steel strand emerging from the mould below. Molten steel is transferred from the AOD converter to the caster using a ladle. The ladle is designed to be strong and insulated. LÄS MER
