  1. 1. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Federico Gatti; [2024]
    Keywords : Robotics; Space Engineering; Docking Maneuvers; Floating Platforms; Nonlinear MPC; MPC; Barrier function; PWM;

    Abstract : Docking maneuvers are a relevant part of the modern space mission, requiring precision and safety to ensure the success of the overall mission. This thesis proposes using a non-linear Model Predictive Control (MPC) as a controller with various constraints to ensure safe docking maneuvers for a satellite. READ MORE

  3. 2. Humidity dependent conductivity of air in HVDC applications and the role of surfaces

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Erik Svensson; [2023]
    Keywords : HVDC; humidity; air conductivity; thin films; HVDC; luftfuktighet; luftkonduktivitet; tunna filmer;

    Abstract : High Voltage Direct Current (HVDC) bushings are insulated devices designed to facilitate the safe passage of electric current across an earthed barrier. Understanding air conductivity is of utmost importance in the design of HVDC components, which is determined by ion density and ion mobility. READ MORE

  4. 3. Numerical Simulations of Resonant Tunnelling Diodes

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Love Sundström; Alexander Holmström Janeld; [2023]
    Keywords : Quantum mechanics; numerical methods; resonant tunnelling diode;

    Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).
