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

6. 5. Investigation of the Magnetic- and Electron Transport Properties of Fe/MgO Superlattices

   University essay from Uppsala universitet/Materialfysik

   Author : Ali Rostom; David Holmgren; [2022]
   Keywords : Fe MgO superlatice; interlayer exchange coupling; Van der Pauw; electronic transport; magnetic field; resistive properties; 3D memory storage;

   Abstract : Anti-ferromagnetic interlayer exchange coupling between iron layers in Fe/MgO superlatices have recently been of interest among researchers for its potential application in 3D memory storage in computers (hard drives) and in the research field of spintronics. Thinfilms and bi-layers between the 10-100 ångström range in thicknesses were analyzed for its resistive properties during different conditions. READ MORE
