1. Sensorless Field-Oriented Control and Position Estimation
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. LÄS MER
2. Investigation of Sensorless Control of Permanent Magnet Synchronous Motor Using High Frequency Injection
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis implements and analyses a sensorless control method for permanent magnet synchronous motors. The purpose is to investigate if the results presented in a study performed by Millinger et al. can be replicated on an industrial grade embedded control system. LÄS MER
3. Sensorlos reglering av en PMSM
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : This thesis is done together with KTH and Husqvarna AB. Husqvarna is one of the leading producers of outdoor power equipment in the world. A chainsaw developed by Husqvarna, that is driven by a permanent magnet synchronous motor (PMSM), is currently controller by a sensorless brushless DC-based controlling strategy. LÄS MER
4. Sensorless Control for Dynamic Testing of Permanent Magnet Synchronous Machines
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : This thesis investigates if it is possible to use the dynamic braking test method together with sensorless control. A literature study is conducted about different sensorless methods in order to find methods that fits the application. From the literature study are two sensorless methods implemented and simulated in Matlab Simulink. LÄS MER
