  1. 21. Testsystem för processtyring

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Josefine Rust; [2017]
    Nyckelord :Testsystem; Temperaturreglering; PID; Mekaniskt Ställdon; Solid State Relä; PLC; Reglering;

    Sammanfattning : Målet med det här arbetet var att implementera och bygga ett komplett testsystem för reglering som efterfrågades av företaget Prevas AB i Karlstad. De önskade ett testsystem som reglerar en vattentemperatur som de kan använda på kontoret för att genomföra egna tester, analyser samt lära nyanställda medarbetare mer om automation. LÄS MER

  3. 22. AN ADAPTIVE CONTROL SYSTEM BASED ON PID, I2PD AND RLS, A SIMULATED DESIGN FOR UAVS

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Johan Gärtner; Philip Johansson; [2017]
    Nyckelord :RLS; PID Controller; UAV; quadrotor; adaptive control; I2PD; simulation;

    Sammanfattning : During this master thesis an adaptive control system for angular velocity was developed. The approach focuses on radio controlled quadrotors and thereby targets a computational efficient solution. The adaptation is divided into two steps. LÄS MER

  4. 23. Position Control of an Electro-Hydraulic Servo-Valve : IDENTIFICATION, MODELLING, CONTROLAND IMPLEMENTATION

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Johan Nilsson; [2016]
    Nyckelord :;

    Sammanfattning : Hydraulic drives, systems that use pressurized fluids as transmis-sion medium, have a wide range of applications are widespread in to-day’s industry. Like many other systems, hydraulic drives can get dra-matically improved performance by an appropriately designed feedback controller. LÄS MER

  5. 24. Attitude and Orbit Control During Deorbit of Tethered Space Debris

    Master-uppsats, KTH/Farkost och flyg

    Författare :Linus Flodin; [2015]
    Nyckelord :space debris mitigation; deorbit; tethered satellites; mathematical modeling; attitude and orbit control system; LQG control; PID control; switched control;

    Sammanfattning : Due to the unsustainable space debris environment in Low Earth Orbit, debris objects must be removed to ensure future safe satellite operations. One proposed concept for deorbiting larger space debris objects, such as decommissioned satellites or spent upper rocket stages, is to use a chaser spacecraft connected to the debris object by an elastic tether, but the required technology is immature and there is a lack of flight experience.

  7. 25. Design and Optimization of Controllers for an Electro-Hydraulic System

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska högskolan

    Författare :Simon André; [2014]
    Nyckelord :Electro-Hydraulic; EH; Controllers; Control strategies; Proportional-Integral-Derivative; PID; Cascade; Feed forward; Linear Quadratic; LQ; Model Predictive Control; MPC;

    Sammanfattning : Electro-Hydraulic (EH) systems are commonly used in the industry for applications that require high power-weight ratios and large driving forces. The EH system studied in this master thesis have recently been upgraded with new hardware components and as a part of this upgrade a new controller was requested. LÄS MER
