  1. 26. Design and implementation of sensor-based and sensorless control of a PMSM test system

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

    Author : Oskar Giesecke; [2019]
    Keywords : ;

    Abstract : Transportation of liquids and gasses in industries in forms of pumping and fanning, constitutes asignificant part of the world-wide electric energy consumption. In order to meet global environmentalgoals of greenhouse gas emissions and sustainable material usage, the development of efficiency andtechnical lifetime of industrial pump and fan technology, are key.

  3. 27. Analytical tool for electromechanical actuators for primary and secondary flight control systems : Optimization of the initial design of the EMA using parametric sizing models

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Albin Linderstam; [2019]
    Keywords : EMA; electromechanical actuators; three-phase synchronous permanent magnet motor; power-offbrake; two-stage planetary gear; ball screw; Saab Avionics Systems;

    Abstract : The number of flights have increased by 80% between 1990 and 2014, and the demand for air travel continues to increase. Even though the aviation sector contributes to economical and social benefits, it still affects the climate change [1]. READ MORE

  4. 28. Modelling a Novel Linear Transverse Flux Machine and Designing a Hysteresis Current Controller for Power Factor Correction

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

    Author : Ahmed Alhaidari; [2019]
    Keywords : double band hysteresis current controller; linear machine; magnetic circuit model; power take-off; transverse flux permanent magnet synchronous machine; wave energy conversion;

    Abstract : In this thesis, the basics of electromagnetic theory for wave-energy conversion are reviewed, some of the characteristics of the ocean wave are investigated, some of the power take-off (PTO) systems are introduced, and details about linear permanent magnetic machines, in particular, are discussed.  The thesis aims to model the novel linear transverse flux machine designed by Anders Hagnestål and to build hysteresis current controller for power factor correc- tion.

  5. 29. Integrated generator for use in aircraft engines

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fredrik Andersson; [2018]
    Keywords : Integrated generator; aircraft engine; generator; aircraft generator; Technology and Engineering;

    Abstract : In this paper the use of integrated generators for airplane engines is examined. In order to accomplish this goal a combination of MatLab with FEMM and ANSYS Maxwell is used to make incrementally more and more detailed analysis of the integrated generator concept. READ MORE

  6. 30. Model Predictive Control of Electric Drives -Design, Simulation and Implementation of PMSM Torque Control

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

    Author : Levente Zsolt Pap; [2018]
    Keywords : PMSM; Field Oriented Control; Model Prediction Control; Inverter; Electric Drive; DSP;

    Abstract : The thesis deals with the design of a permanent magnet synchronous machine controller that isimplemented on an embedded platform to replace the off-the-shelf controller currently being used in theelectric race car of the KTH Formula Student team. Software implementation of the control algorithmwas tested in laboratory environment on the hardware prototype of a 2-level three-phase voltage sourceinverter. READ MORE
