  1. 1. Nonlinear MPC for Motion Control and Thruster Allocation of Ships

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Alexander Bärlund; [2019]
    Nyckelord :MPC; nonlinear MPC; model predictive control; thruster allocation; thrust allocation; motion control; motion control system; ship; dynamic positioning; azimuth; azipod;

    Sammanfattning : Critical automated maneuvers for ships typically require a redundant set of thrusters. The motion control system hierarchy is commonly separated into several layers using a high-level motion controller and a thruster allocation (TA) algorithm. LÄS MER

    Nyckelord :;

    Sammanfattning : The ferry line company VIKING LINE has put in an order for a new vessel with a planned delivery for the year 2020. The vessel will berth and depart daily from the Stockholm port, Stadsgården. The vessel is equipped with two 10 MW Azipod propeller systems. LÄS MER

  5. 4. Estimation of Ship Properties for Energy Efficient Automation

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Lucas Nilsson; [2016]
    Nyckelord :System identification; ship properties; energy efficient; automation; ship modelling; estimation; signal processing; simulation; ship dynamics; cusum; cumulative summation; change in dynamics; load condition; podded propulsion; azipod; yaw dynamics; noise impact; measurement noise; model error; bias due to model error; ship yaw model; moment of inertia; estimate ship properties; ship automation;

    Sammanfattning : One method to increase efficiency, robustness and accuracy of automatic control, is to introduce mathematical models of the system in question to increase performance. With these models, it is possible to predict the behavior of the system, which enables control according to the predictions. LÄS MER

  7. 5. A Study of the Twin Fin Concept for Cruise Ship Applications

    Master-uppsats, KTH/Marina system

    Författare :Frida Nyström; [2015]
    Nyckelord :;

    Sammanfattning : The aim with this thesis is to investigate if the Twin Fin concept can be a beneficial propulsion system for large cruise ships, about 300 m long. The Twin Fin concept is a new propulsion system, launched in 2014 by Caterpillar Propulsion [1]. LÄS MER
