4. 3. Kalman-Filter Design and Evaluation for PMSM Rotor-Temperature Estimation

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Daniel Mårtensson; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The permanent magnet synchronous motor, PMSM, is an efficient electrical motor that has seen a greater prevalence in the automotive industry from the increasing demand for electrical vehicles. Managing the temperature of the permanent magnet rotor is important to optimize motor utilization and avoid hardware failures. LÄS MER
