    Sammanfattning : The presented work in this report is a master’s thesis at the machine design track at KTH Royal Institute of Technology. The work was commissioned by Ovzon through Svea Teknik AB. The T6 antenna in Ovzons antenna terminal portfolio is as of now fully manual in terms of positioning against satellites. LÄS MER

  3. 2. Autonomous landing of multicopters on mobile platforms : Design of an autonomous landing solution for multicopters on mobile platforms, based on a ultrasonic local positionning technology

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Mathias Peluchon; [2019]
    Nyckelord :;

    Sammanfattning : This work studies the use of an ultrasonic 3D positioning system in multicopter landing applications. Its aim is to develop a solution for autonomous landing of rotary wings systems on mobile platforms, especially boat decks using the positioning system developed by the French startup Internest.

    Nyckelord :Adaptive Notch Filter; Back-EMF; Electric Motor Position Control; Error Modelling; Field-Oriented Control; Hybrid Stepper Motor; Kalman Filter; Load Angle; Magnetic Rotary Position Sensor; Sensorless Control; Sliding Window Discrete Fourier Transform; Stall Detection and Prediction.;

    Sammanfattning : Hybrid stepper motors are a common type of electric motor used throughout industry thanks to its low-cost, high torque at low speed and open loop positioning capabilities. However, a closed loop control is often required for industrial applications with high precision requirements. LÄS MER

  5. 4. Automatiserad provrörskarusell : Elektronikkonstruktion och utvärdering

    M1-uppsats, Signaler och System

    Författare :Carl Rosenfeld; [2010]
    Nyckelord :Rotary Positioning; stepper motor; magnetic rotary encoders; linear speed ramp; Roterande positionering; stegmotor; magnetisk rotationsgivare; rampning;

    Sammanfattning : Den här rapporten beskriver arbetet med en automatiserad provrörsförflyttare. Det är ett examensarbete som har gjorts på företaget Q-linea AB. En karuselliknande konstruktion med en stegmotor användes för att flytta prover mellan ett antal positioner. En mikrokontroller som hanterar styrning och sensordata har programmerats i C. LÄS MER
