Abstract :
In this paper, a control scheme for an AC servomotor drive using a permanent magnet synchronous motor is presented and analyzed. In the proposed scheme, fuzzy logic is used to estimate the rotor position and generate the reference currents. Two strategies, maximum torque and unit power factor, are analyzed using numerical simulation and their performances are shown
