  1. 1. Automatic Tuning of Motion Control System for an Autonomous Underwater Vehicle

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Markus Andersson; [2019]
    Nyckelord :Automatic Control; Automatic Tuning; Control; Motion Control; Modelling; System Identification; Online Identification; Underwater Vehicle; Autonomous Underwater Vehicle; AUV; SMaRC; Maribot LoLo; Differential drive;

    Sammanfattning : The interest for marine research and exploration has increased rapidly during the past decades and autonomous underwater vehicles (AUV) have been found useful in an increased amount of applications. The demand for versatile platform AUVs, able to perform a wide range of tasks, has become apparent. LÄS MER

  3. 2. How to Keep an Unbalanced Aircraft Balanced : Control Surfaces and Thrust Vectoring

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

    Författare :Adam Olsson; David Jacobsson; [2019]
    Nyckelord :;

    Sammanfattning : To balance and control different aircraft, it is often necessary to use some type of control system, the less stable the craft is without any control system, the more advanced the system is required to be. This project is an experiment which purpose is to attempt to control a very unstable craft using steerable rudders. LÄS MER

  4. 3. Truster till förskeppet på NGU/A26 : Dimensionering och konceptgenerering

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Elektricitetslära

    Författare :Emil Riddervold Sandberg; Markus Lindblom; [2017]
    Nyckelord :CAD; Truster; FMV; A26; NGU; Koncept; Positionering; Ubåt; Konstruktion; Design; Försvarets Materielverk;

    Sammanfattning : This thesis work has been conducted on the behalf of the Swedish Defense Material Administration, which by directive from the Swedish Armed Forces has procured two new submarines of type A26 for delivery in 2024. For certain operations A26 will need to be able to be dynamically positioned in water currents of various speeds. LÄS MER

  5. 4. Design and models optimisation of asailing yacht dynamic simulator

    Master-uppsats, KTH/Marina system

    Författare :Paul Kerdraon; [2017]
    Nyckelord :;

    Sammanfattning : This master thesis is concerned with the design and optimisation of a dynamic velocity prediction programmefor high performance sailing yachts. The simulator uses response surfaces methods, maximising the computationaleciency. LÄS MER

  7. 5. Accuracy of transient versus steady state forces on a rudder operating in a propeller slipstream

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Erik Löfgren; [2015]
    Nyckelord :Unsteady flows; rudders; propellers; fluid mechanics; performance prediction; unsteady aerofoils;

    Sammanfattning : In computational fluid dynamics (CFD), a transient simulation is in general more costly than computing the steady state of the system, if such a state exists. The velocity field produced by the propeller blades upstream of a rudder is transient in nature, and rudder design using CFD may therefore become very time-consuming. LÄS MER
