  1. 16. Electrohydraulic Power Steering Simulation : Dynamic, thermal and hydraulic modelling

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

    Author : Oskar Svensson; [2019]
    Keywords : PMSM; SVPWM; vector control; FOC; lumped parameter model; LPM; hydraulic pump; simulation;

    Abstract : There are several benets of electrohydraulic power steering systems, as compared to hydraulicpower steering systems where the pump is driven directly by the engine of the vehicle. Someof these benets are increased eciency and improved steering performance. READ MORE

  3. 17. Rapid soil quality assessment using portable visible near infrared (VNIR) spectroscopy

    University essay from SLU/Dept. of Soil and Environment

    Author : Getachew Gemtesa Tiruneh; [2014]
    Keywords : visible-near infrared; soil; Ethiopia; PLS; spectroscopy;

    Abstract : Visible-Near Infrared (VNIR) spectroscopy provides rapid, low cost, non-destructive and simultaneous measurements of several constituents from a single scan. The method has recently gained attention as an alternative to conventional soil analytical techniques in soil quality assessment. READ MORE

  4. 18. Design and implementation of a servo system by Sensor Field Oriented Control of a BLDC motor

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Per Eriksson; [2014]
    Keywords : Field oriented control; Vector Control; BLDC; Servo system; Regulator; Synchronous motor; PWM; SVPWM;

    Abstract : A servo system intended to steer antennas on board ships is designed, built and tested. It uses a Brushless Direct Current (BLDC) motor with an encoder to keep track of its position, and Field Oriented Control (FOC) implemented on Toshibas microprocessor TMPM373 in order to control the current flowing to the motor.

  5. 19. FPGA Based Sensorless Control of a Permanent Magnet Synchronous Motor

    University essay from KTH/Elektrisk energiomvandling

    Author : Ali El Hafni; [2012]
    Keywords : ;

    Abstract : Field Oriented Control (FOC) has proven to be a high performance and robust control strategy for electrical drives. However the states of the machine, namely speed and/or position, have to be measured in this control strategy. READ MORE

  6. 20. Controller-Inverter for Sensorless Permanent Magnet Synchronous Motors : Application in Onboard Electric Powertrain for Uphill Propulsion in Downhill Mountain Biking

    University essay from KTH/Elektrisk energiomvandling

    Author : Mattias Rahm; [2012]
    Keywords : field oriented control; permanent magnet synchronous motor; sensorless control; electric vehicle;

    Abstract : This thesis demonstrates a practical implementation of a sensorless permanent magnet synchronousmotor (PMSM) drive for vehicle propulsion. The main design parameters and overall properties of themotor drive are derived for the case of an on-board electric powertrain as a substitute to the lift shuttle indownhill (DH) mountain biking.
