  1. 1. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Federico Gatti; [2024]
    Nyckelord :Robotics; Space Engineering; Docking Maneuvers; Floating Platforms; Nonlinear MPC; MPC; Barrier function; PWM;

    Sammanfattning : Docking maneuvers are a relevant part of the modern space mission, requiring precision and safety to ensure the success of the overall mission. This thesis proposes using a non-linear Model Predictive Control (MPC) as a controller with various constraints to ensure safe docking maneuvers for a satellite. LÄS MER

  3. 2. Predictive Controllers for Load Transportation in Microgravity Environments

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

    Författare :Sujet Phodapol; [2023]
    Nyckelord :Model Predictive Control; Decentralized control; Multi-robot systems; Space technology; Modell-prediktiv reglering; Decentraliserad reglering; Multirobotsystem; Rymdteknologi;

    Sammanfattning : Space activities have been increasing dramatically in the past decades. As a result, the number of space debris has also increased significantly. Therefore, it is necessary to clean up and remove them to prevent a collision between space debris and spacecraft. LÄS MER

  4. 3. Data Driven Model Identification for Remote Electrical Tilt Systems

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Raphaël Ashruf; [2023]
    Nyckelord :;

    Sammanfattning : This thesis explores the use of supervised machine learning for modelling the dynamics of Remote Electrical Tilt (RET) telecom systems. Three methodologies, including linear regressionfor linear dynamics models, Gaussian Process (GP) regression, and Recurrent Neural Networks (RNN) with Gated Recurrent Units (GRU) are proposed.

  5. 4. System Identification of a Fixed-Wing UAV Using a Prediction Error Method

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Trulsa Eriksson; [2023]
    Nyckelord :System identification; Fixed-wing UAV; Modelling; Parameter estimation;

    Sammanfattning : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle.

  7. 5. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Viktor Svensson; Robin Raymundsson; [2023]
    Nyckelord :Acoustic; defect; detection; harmonic; Akustisk; defekt; detektion; överton;

    Sammanfattning : When aluminium profiles are manufactured, defects may arise, especially when theprofiles are manufactured through extrusion. During the extrusion process, thesedefects occur on parts of the extruded material because of contaminates that needto be found. LÄS MER
