  1. 1. Automatisering av rökgasrening : Slangfiltersystem med Siemens PLC & HMI

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Samuel Baltenius; [2021]
    Nyckelord :PLC; HMI; Rökgasrening; Slangfilter; Slangrad; Siemens; Adaptivt;

    Sammanfattning : Detta arbete behandlar hur ett Siemens PLC system konstrueras och programmeras för att automatisera rengöringen av textilslangar vid rökgasrening. Det gjordes genom att undersöka kravsammanställning och utforma systemet därefter. För systemet togs kopplingsscheman fram, programmering av virtuell PLC och HMI gjordes. LÄS MER

  3. 2. Blind Channel Equalization for Shortwave Digital Radio Communications

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tomas Busk; [2020]
    Nyckelord :Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Sammanfattning : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

  4. 3. GPS-oscillation-robust Localization and Visionaided Odometry Estimation

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :HONGYI CHEN; [2019]
    Nyckelord :Adaptive Extended Kalman Filter; Localization; Stereo visual odometry; GPS outage; Adaptivt förlängt Kalmanfilter; lokalisering; stereovisuell odometri; GPS avbrott;

    Sammanfattning : GPS/IMU integrated systems are commonly used for vehicle navigation. The algorithm for this coupled system is normally based on Kalman filter. However, oscillated GPS measurements in the urban environment can lead to localization divergence easily. LÄS MER

  5. 4. Stabilization of Manually Controlled Sight-Systems for Tracking Tasks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Steffany Reyna Marquez; [2019]
    Nyckelord :;

    Sammanfattning : In this thesis, we analyze the influence of an operator during manual control tasks in order toimprove her tracking ability. The operator sends control commands to a sight system so that shecan, among other things, track a target. LÄS MER

  7. 5. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation & Choosing DPSS Parameters

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Carl-Henrik Hanquist; [2018]
    Nyckelord :DPSS; Multitaper; Radar;

    Sammanfattning : One of the biggest challenges in any airborne radar is to distinguish a target from a strong ground echo. The main problem is that the ground echo, called ground clutter, can be up to a million times stronger than the response from the target in question. LÄS MER
