| Abstract |
This paper addresses the problem of wide speed range sensorless control of a surface mount
permanent magnet (SMPM) machine including zero speed operation. A new hybrid structure
integrating a flux observer and signal injection techniques is proposed which results in a rotor position signal independent of motor parameters at low and zero speed. Experimental results are presented
showing excellent performance for both sensorless speed and position control. |
