Abstract

The paper reports on sensorless control methods for permanent magnet machine drives at low speed, analysing the most promising approaches for sensorless control at low speed, which are the INFORM (indirect flux detection by online reactance measurement) method and the high frequency injection (HF Injection). In order to compare both methods, they are derived using the same voltage equation. This context is often missing in literature. Furthermore, the effect of the rotor position estimation on the overall motor control is characterised. This is necessary to set limits for stable operation areas of the motor. Theoretical foundations are substantiated by simulations.
