    Sammanfattning : Decreasing energy consumption has become increasingly important in recent times due to climate change. The average temperature is increasing across the planet, and with it, an increase in droughts and other climate disasters can be seen. There are multiple ways to decrease energy consummation, and one of them is to regulate the light in a building. LÄS MER

  3. 2. Automatic audio sample finder for music creation : Melodic audio segmentation using DSP and machine learning

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

    Författare :David Pituk; [2019]
    Nyckelord :;

    Sammanfattning : In the field of audio signal processing, there have always been attempts to cre- ate tools which help musicians by automating processes for music creation or analysis, and the electronic music industry is still playing an important role in the combination of software engineering and music.  In the age of sample based synthesizers and sequencers, creating and using high quality and unique audio sample packages is a crucial part for composing songs.

  4. 3. Sensorless algorithm for synchronous machines using current oversampling and PWM harmonics

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

    Författare :Giorgio Gullone; [2018]
    Nyckelord :;

    Sammanfattning : Sensorless-controlled drives represent a solution drawing an increasinglyimportant attention for the benefits they entail. At the cost ofa slightly lower dynamics compared with the traditional drives, theyinvolve a reduction of the system costs and complexity and improvednoise immunity and reliability. LÄS MER

  5. 4. PID tuning with Ant Colony Optimization (ACO) : A framework for a step response based tuning algorithm

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Carl Johan Björk; [2018]
    Nyckelord :PID; self-tuning; control system; building automation; ant colony optimization; neural networks; open-loop; closed-loop; step response.; PID; självtrimning; reglersystem; byggnadsautomation; myrkolonioptimering; neurala nätverk; öppen slinga; sluten slinga; stegsvar.;

    Sammanfattning : The building automation industry lacks an affordable, simple, solution for autonomous PID controller tuning when overhead variables fluctuate. In this project, requested by Jitea AB, a solution was developed, utilising step response process modelling, numerical integration of first order differential equations, and Ant Colony Optimization (ACO).
