  1. 11. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays

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

    Författare :Jesper Brunnström; [2021]
    Nyckelord :Active noise control; Secondary path modelling; Spatial; Adaptive filter; Multichannel; Least mean squares; Aktiv brusreducering; Sekundärvägsmodellering; Spatial; Adaptiv Filtrering; Multikanal; Minsta kvadratmetoden;

    Sammanfattning : In this work we explore online secondary path modelling (SPM) in the context of spatial active noise control (ANC). Specifically, we are interested in the reduction of broadband noise over a three-dimensional region, without restrictions on microphone and loudspeaker array placement. LÄS MER

  4. 13. Reference Tracking with Adversarial Adaptive Output- Feedback Model Predictive Control

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

    Författare :Linda Bui; [2021]
    Nyckelord :Model Predictive Control; Adversarial Multi-Armed Bandits; Kalman Filter; Output-Feedback; Adaptive Control ; Modell Prediktiv Reglering; Kontradiktoriska Flerarmade Banditer; Kalman Filter; Output-Feedback; Adaptiv Reglering;

    Sammanfattning : Model Predictive Control (MPC) is a control strategy based on optimization that handles system constraints explicitly, making it a popular feedback control method in real industrial processes. However, designing this control policy is an expensive operation since an explicit model of the process is required when re-tuning the controller. LÄS MER

  5. 14. Localisation and Mapping for an Autonomous Lawn Mower : Implementation of localisation and mapping features for an autonomous lawn mower using heterogeneous sensors

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

    Författare :Marco Boffo; [2021]
    Nyckelord :Autonomous Mobile Robot; Sensor Fusion; Localisation; Mapping; Robot mobili autonomi; fusione di sensori; localizzazione; mappatura; Autonom mobil robot; sensorfusion; lokalisering; kartläggning;

    Sammanfattning : Autonomous lawn mowers have been available to consumers for more than 20 years. During this period, advancements in embedded device computations and sensor performance have led to improvements in the reliability of these robots. Despite recent improvements, the opportunity for further innovation of such systems remains significant. LÄS MER

  7. 15. Implementation of Spectrum Analysis Functionality for IQ-Signal.

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Författare :Gedion Biredaw Anbessa; [2020]
    Nyckelord :RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

    Sammanfattning : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).
