  1. 1. Blind Acoustic Feedback Cancellation for an AUV

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Hampus Frick; [2023]
    Nyckelord :acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Sammanfattning : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. LÄS MER

  3. 2. Harmonic Filters For Electronic Drive Systems Targeting Aircraft Applications

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

    Författare :Emelie Berglund; [2023]
    Nyckelord :Active Cancellation Filter; BLDC;

    Sammanfattning : Climate change pressures fossil-driven vehicles into electrification to sustain a healthy planet and environment for its inhabitants. Air traffic contributes to the ongoing climate crisis, and electric aircraft is taking its toll on the avionics market. LÄS MER

  4. 3. Isolated Single-Stage Interleave Resonant PFC Rectifier with Active and Novel Passive Output Ripple Cancellation Circuit

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Abidemi Oluremilekun Eleyele; [2020]
    Nyckelord :single-stage AC DC converter; bridgeless power factor correction PFC rectifier; active passive ripple cancellation; zero current switching ZCS ; zero voltage switching ZVS ; Electric vehicle EV charger; LLC;

    Sammanfattning : With the increasing demand for fast, cheaper, and efficient power converters come the need for a single-stage power factor correction (PFC) converter. Various single-stage PFC converter proposed in the literature has the drawback of high DC bus voltage at the input side and together with the shift to wide bandgap switches like GaN drives the converter cost higher.

  5. 4. Implementation of Adaptive Filter Structures on a Fixed Point Signal Processor for Acoustical Noise Reduction

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :Krishna Chaitanya Chunduri; Chalapathi Gutti; [2005]
    Nyckelord :Noise reducation; Adaptive filter structures; Fixed point procesor;

    Sammanfattning : The problem of controlling the noise level in the environment has been the focus of a tremendous amount of research over the years. Active Noise Cancellation (ANC) is one such approach that has been proposed for reduction of steady state noise. LÄS MER
