Abstract

In this paper, using the adaptive sliding mode observer for speed sensorless vector control is proposed. Adaptive sliding mode observer of the motor stator coordinate system using the voltage equations of the rotor flux components are observed. Motor speed was obtained by the Lyapunov function is estimated by the relationship further. In order to establish such a control scheme based on the way conventional PI controller and sliding mode observer annexing characteristics of the system through simulation and experiment were compared. According to analysis by comparison with the usefulness of the system was confirmed.

본 논문은 슬라이딩 모드 관측기를 이용한 적응 속도 센서리스 벡터제어에 대해 제안한다. 적응 슬라이딩 모드 관측기는 전압식을 이용한 전동기 고정자 기준좌표에 의해 회전자 자속성분이 관측된다. Lyapunov 함수에 의해 얻어지는 추가적인 관계로부터 전동기의 속도가 구해진다. 성능 확인을 위해 전통적인 PI 제어기와 슬라이딩 모드 관측기의 추가적인 특성에 대해 시뮬레이션과 실험을 통해 비교하였다. 분석과 비교에 의한 결과에 의하면 시스템의 유용성을 확인할 수 있었다.
