  1. 1. Real-time Optimal Braking for Marine Vessels with Rotating Thrusters

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Sigurlaug Rún Jónsdóttir; [2022]
    Nyckelord :Nonlinear optimization; nonlinear optimal control; numerical optimal control; real-time solution; optimal braking; receding horizon; modeling; ship model; propeller forces; rudder forces; direct multiple shooting method; discretization;

    Sammanfattning : Collision avoidance is an essential component of autonomous shipping. As ships begin to advance towards autonomy, developing an advisory system is one of the first steps. An advisory system with a strong collision avoidance component can help the crew act more quickly and accurately in dangerous situations. LÄS MER

    Sammanfattning : Many engineering problems are naturally posed as optimal control problems. It may involve moving between two points in the fastest possible way, or to put a satellite into orbit with minimum energy consumption. Many optimal control problems are too difficult to be solved analytically and therefore require the use of numerical methods. LÄS MER
