- Alternative Abstract
- This paper compares and analyzes the estimation performance for IPMSM (Interior Permanent Magnet Synchronous Motor) by sensorless control methods. In general, the sensorless drive system of IPMSM estimates the speed and phase angle of the rotor using different methods depending on the rotational speed. There are two methods, one is injecting high frequency voltage and the other is extended electromotive force (EEMF) based sensorless control method. In the stationary and low speed regions of the IPMSM, a sensorless control method using high frequency voltage injection is used. And in the high speed region, EEMF based sensorless control method is used. In this paper compares and analyzes the rotor speed and phase angle estimation performance of each sensorless control method according to the rotational speed of IPMSM through simulations performed under the same conditions.
