  1. 1. Influence of current harmonics on the degradation of the catalyst coated membrane in PEMFC

    University essay from KTH/Kemiteknik

    Author : Evelina Ahlén Norberg; [2022]
    Keywords : Proton Exchange Membrane Fuel Cell; Ripple Current; Current Harmonics; Degradation; Marine transportation; Polymerelektrolytbränslecell; Rippelström; Strömoscillation; Åldring; Sjötransport;

    Abstract : Sjöfarten är idag dominerad av förbränningsmotorer som är beroende av fossila drivmedel. Elektrifiering är en av huvudstrategierna för att möjliggöra fossilfri energiförsörjning inom internationell sjöfart. READ MORE

  3. 2. Robust Model Predictive Control for Marine Vessels

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Allan Andre do Nascimento; [2018]
    Keywords : Robust control; Tube MPC; marine vessel control; Robust kontroll; Tube MPC; fartygskontroll;

    Abstract : This master thesis studies the implementation of a Robust MPC controllerin marine vessels on different tasks. A tube based MPC is designed based onsystem linearization around the target point guaranteeing local input to statestability of the respective linearized version of the original nonlinear system.
