Abstract :
In this paper, a simpler but more effective sensorless control scheme is proposed for an interior permanent-magnet synchronous motor drives at very low speed. Compared to the commonly method using three filter to extract rotor position signal, the new method uses only one low pass filter, leads to a lower implementation processing time, the simulations have proved the correctness and validity of this method.
