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

    University essay from Linköpings universitet/Reglerteknik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Adam Olsson; David Jacobsson; [2019]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from KTH/Marina system

    Author : Paul Kerdraon; [2017]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Umeå universitet/Institutionen för fysik

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

    Abstract : 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. READ MORE

  6. 5. KOMPOSITER I UNDERVATTENSFARKOSTER

    University essay from KTH/Lättkonstruktioner; KTH/Undervattensteknik
