| Abstract |
The paper presents a position sensorless vector
control able to drive Interior Permanent Magnet
Synchronous Motors in any operating conditions, including
low and zero speed. According to the proposed approach a
constant frequency sinusoidal signal (voltage or current) is
injected in the machine along a given direction so that,
thanks to the rotor saliency, a periodic stator signal
component is generated along a direction orthogonal to that
of the injected signal. The amplitude of such an orthogonal
signal depends on the phase displacement between the rotor
d axis and the direction along which the additional signal is
injected. A robust rotor position tracking is obtained by
adjusting the direction of the additional signal in order to
minimize the amplitude of the generated orthogonal
response. Experimental results confirm the validity and
good performance of the proposed sensorless technique. |
