Abstract :
Sensorless vector control has been studied broadly, and motor speed identification is exactly very important. According to the fundamental equations of asynchronous motor for vector control, a MRAS speed identification algorithm is obtained by measured motor stator voltage and currents. The simulation result shows that this MRAS speed identification model meets the needs of dynamic characteristic and identification precision.
