Abstract :
Rotational sensorless control methods are one of the motor control methods with high performance and high reliability. One of the technical issued with the rotational speed sensorless controlled AC motors is to re-start their operation when inverters stop and the rotor speed or angle estimation. There several method to cope with the problems and they are reviewed in this paper.
