  1. 11. Autonomous Docking of Electric Boat

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :LUDVIG BOCZAR; JONATHAN PERNOW; [2021]
    Nyckelord :Autonomous Boat; Boat Docking; Radar; Model Predictive Control; Motion Control; Autonom Båt; Båttilläggning; Radar; Modellprediktiv Reglering; Rörelsestyrning;

    Sammanfattning : In recreational boating, docking is one of the most stressful and accident prone situations. Due to the loss of maneuverability at low speeds, it is a procedure that requires experience. LÄS MER

    Sammanfattning : In recent years, the Helicon Plasma Thruster (HPT) has become one of the most promising technologies of in-space electric propulsion. T4i Technology for Propulsion and Innovation S.P.A. LÄS MER

  5. 14. Control and Autonomy of a Water Quality Measuring Unmanned Surface Vehicle (USV) : Catfish project - Control and Autonomy

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad

    Författare :Vidar Hårding; [2021]
    Nyckelord :catfish; control and autonomy; pixhawk; usv; motor configurations; catfish; kontroll och autonomi; pixhawk; vattendrönare; motorkonfiguration;

    Sammanfattning : This report is about the implementation of autonomy and control on a water quality measuring unmanned surface vehicle. The project was termed Catfish and involved five teams focusing on different aspects of the initial goal to create an autonomous three-part system; a surface drone, a submerged drone and flying drone.

  7. 15. Design, simulation, and testing of an electric propulsion cluster frame

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jeremy Bek; [2021]
    Nyckelord :Electric propulsion; gridded ion thruster; cluster; frame; thermal modelling; mechanical modelling; lumped-parameter model.; Elektrisk framdrivning; jonmotor; kluster; ram; termisk modellering; mekanisk modellering; klumpelementmodell.;

    Sammanfattning : In general, electric propulsion offers very high efficiency but relatively low thrust. To remedy this, several ion engines can be assembled in a clustered configuration and operated in parallel. This requires the careful design of a frame to accommodate the individual propulsion systems. LÄS MER
