Single sensor three-phase permanent magnet synchronous motor drive based on Luenberger style-observers
Hafez, B.; Abdel-Khalik, A.; Massoud, Ahmed; Ahmed, S.; Lorenz, R. D. ( IEEE , 2012 , Conference Paper)This paper presents a technique to estimate phase currents and rotor position in a vector-controlled PMSM drive using only dc-link current measurement. Three cascaded Luenberger style observers were used to perform this ... -
Single-sensor-based three-phase permanent-magnet synchronous motor drive system with luenberger observers for motor line current reconstruction
Hafez, B.; Abdel-Khalik, A. S.; Massoud, Ahmed; Ahmed, S.; Lorenz, R. D. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)This paper presents an algorithm that enables single-sensor operation of vector-controlled three-phase permanent-magnet-synchronous-motor voltage source inverter (VSI)-based drive systems. The closed-loop operation is ...
