  1. 1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

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

    Author : Simon Weideskog; [2024]
    Keywords : FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Abstract : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. READ MORE

  3. 2. Beyond Pulse Position Modulation : a Feasibility Study

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Danielle Gustafsson; [2023]
    Keywords : telecommunications; pulse position modulation; error-correction;

    Abstract : During the thesis work, a feasibility study of the BPPM error-correction protocol is performed. The beyond pulse position modulation (BPPM) protocol was invented at Ericsson AB and describes a modulation encoding using vertically and horizontally polarized single photons for optical transmission and error-correction.

  4. 3. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Saga Westerberg; [2023]
    Keywords : Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

    Abstract : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index.

  5. 4. Communication and Error Correction via Polarisation of Single Photons and Time Ordering

    University essay from KTH/Tillämpad fysik

    Author : Shek Lun Leung; [2023]
    Keywords : Quantum Technology; Physics; Photon; Telecommunication; polarization; time ordering; BPPM; PPM; OOK; Simulation; quantum communication; Kvantteknologi; Fysik; Foton; Telekommunikation; polarisering; tidsordning; BPPM; PPM; OOK; Simulering; kvantkommunikation; satellite communication;

    Abstract : This research study aims to investigate the capacity of single photons to carry information through polarization and time ordering and proposes a protocol called Beyond Pulse Position Modulation (BPPM) to improve photon-based communication reliability over longer distances with limited power. Such a protocol may be used in any communication scenario where energy efficiency is important, e. READ MORE

  6. 5. Modelling and design of PMSM position drivesusing model following control

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : JACOB RÖING; CARL JENSEN; [2021]
    Keywords : ;

    Abstract : Teenage Engineering is a Swedish electronics company that want to automate their quality control process. For this purpose, they want to develop a test jig that can perform tactile testing of their products. The test jig will utilize PMSM motors for position control of the end-effector. READ MORE
