This paper focuses on estimation of rotor position for high fundamental frequency PM machines using back-EMF. The paper proposes a self-sensing vctor control algorithm that combines the following: 1) a motion observer with torque feed-forward, 2) a modified current observer in the synchronous frame, and 3) a precise discrete-time implementation. Extensive experimental results are provided on a bearingless motor with speeds up to 60 kRPM.
