Position sensorless control of interior permanent magnet machine

摘要

How to control the IPM machine having a rotor saliency. Stator terminal signal is measured, the synchronous reference frame current signal is obtained by being rotated. Rotor position is estimated based on the impedance in the current signal is generated using a rotor. Rotor position estimated is used to control the machine. The alternator method is used - starter system can while providing operating efficiency, to provide a power generating high cranking torque over a wide speed range.
