1. RoBuoy : Dynamic Positioning of an Autonomous Buoy using GNSS
Kandidat-uppsats, KTH/MekatronikSammanfattning : Buoys anchored to the seabed are often used for marking courses in competitive sailing and other water sports, but they may need to be relocated several times per day. To avoid the time and fuel consuming labour of raising and moving the anchors, a prototype of an autonomous buoy using electric motors to maintain its position was built and tested. LÄS MER
2. Hardware-In-the-Loop simulation of a small scale prototype of a Wave Energy Converter
Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : Renewable energy sources are a hot topic, both when it comes to climate change and the constant increase in demand of electricity due to population growth and a more electrified society. One such energy source is wave energy - an energy source with great potential but still relatively new with the need for further development. LÄS MER
3. Design and implementation of sensor-based and sensorless control of a PMSM test system
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Transportation of liquids and gasses in industries in forms of pumping and fanning, constitutes asignificant part of the world-wide electric energy consumption. In order to meet global environmentalgoals of greenhouse gas emissions and sustainable material usage, the development of efficiency andtechnical lifetime of industrial pump and fan technology, are key.

4. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

5. Motor unit localization using high-density surface EMG
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Localization of muscle motor units (MU) using surface electromyography (sEMG) is of interest in areas including neurology, rehabilitation and prosthetic control. The aim of the thesis is to describe a method for MU localization using high-density sEMG (HDsEMG) and verify the method using simultaneous intramuscular EMG (iEMG) recordings. LÄS MER
