  1. 1. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

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

    Author : Erik Lindberg; [2023]
    Keywords : Variable speed drives; Sensorless control; Luenberger observer; Synchronous reluctance machine; Permanent magnet synchronous machines; Vector control; Model reference adaptive system; Variabel hastighetsreglering; Sensorlös reglering; Luenberger observatör; Synkron reluktansmaskin; Permanentmagnetmaskin; Vektorreglering; Adaptiv modelreferensreglering;

    Abstract : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps.

  3. 2. Steering Control During μ-split Braking for an Autonomous Heavy Road Vehicle

    University essay from Linköpings universitet/Fordonssystem

    Author : Sebastian Haglund; Henrik Johansson; [2020]
    Keywords : steering; braking; autonomous; μ-split; split-μ; truck; vehicle; control;

    Abstract : A critical maneuver for a heavy vehicle is braking with different friction on the left and right hand side of the vehicle, called μ-split. This results in an unwanted yaw torque acting on the vehicle. During this situation, the driver maintains the lateral stability and follows the desired path by corrective steering. READ MORE

  4. 3. A Novel, Wave-based Control Architecture for Collaborative Haptic Virtual Environments

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

    Author : Nils Jörgensen; [2019]
    Keywords : ;

    Abstract : Haptic feedback, the introduction of sense-of-touch into virtual environments, has been shown to have many benefits in practical applications. One such area of interest, is the increased performance of tasks that require collaboration. READ MORE

  5. 4. Space Situational Awareness with the Swedish Allsky Meteor Network

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Simon Alinder; [2019]
    Keywords : SSA; space situational awareness; IOD; initial orbit determination; orbit determination; satellite identification; all-sky; rymdlägessituation; SSA; omloppsbana; banbestämning;

    Abstract : This thesis investigates the use of the Swedish Allsky Meteor Network (SAMN) for observing, identifying, and determining the orbits of satellites. The overall goal of this project is to determine the feasibility of using such a network for Space Situational Awareness (SSA) purposes, which requires identification and monitoring of objects in orbit.

  6. 5. Design and Implementation of an Exogenous Kalman Filter for UAVs

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

    Author : Patrik Sjöberg; [2018]
    Keywords : ;

    Abstract : State estimations for nonlinear systems are often done using the ExtendedKalman Filter (EKF), which has good performance in terms of minimum variancefor the estimation error. However, global stability is not guaranteed,and the filter has a risk of becoming unstable. READ MORE
