| Abstract |
This paper presents a control method for
permanent magnet (PM) motors based on a combination of
a non linear full–order observer and a signal injection
scheme. Mechanical–sensorless operating range down to
zero speed is obtained using only voltage and current
sensors. The signal injection scheme uses the asymmetry of
the motor’s d and q axis inductances to estimate rotor
position and speed. Such asymmetry is also taken into
account in the motor model used to construct the observer.
The performance of the proposed scheme is validated
through experimental results. |
