A Speed Sensorless Vector Control for Permanent Magnet Synchronous Motors using the Integral Binary Observer

적분스위칭평면을 갖는 바이너리 관측기를 이용한 영구자석 동기전동기의 속도 및 위치센서리스 제어

This paper presents a speed and position sensorless control of permanent magnet synchronous motors using an integral binary observer. In order to improve the steady state performance of the binary observer, the binary observer is formed by adding extra integral dynamics to the switching hyperplane equation. The observer structure and its deign method are described. The experimetntal results of the proposed algorithm are presented to demonstrate the effectiveness of the approach.
