Stability of Sensorless Speed Control of PMSM Using State Observer
상태관측기를 이용한 영구자석 동기전동기의 센서리스 속도제어의 안정도
Abstract
Sensorless PMSM is much studied for the industrial applications and home appliances because a mechanical sensor reduces reliability and increases cost. This paper studies the stability of sensorless speed control of PMSM using state observer. Sensorless control scheme using state observer is known as a scheme having a comparatively good performance. Several papers have studied the stability of state observer control scheme, but have not considered parameter variation which is important to sensorless control. This paper studies the stability through computer simulation in case of parameter variation.
