Stator Flux Oriented Vector Control of Interior Permanent Magnet Synchronous Motors with Maximum Power Factor Per Ampere Strategy

Permanent magnet synchronous motors attract more attentions in motion control application in recent years. In this paper a novel stator flux oriented vector control scheme with maximum power factor to current trajectory is presented for a permanent magnet synchronous motor. This system is then implemented in Matlab/Simulink and the motor performance under this control method is investigated via excessive simulation results. Finally, the effect of stator resistance on the power factor of motor is shown.
