Abstract

This paper proposes a new fuzzy load torque observer and a fuzzy speed regulator to guarantee a robust speed control of a permanent magnet synchronous motor (PMSM). Also, the LMI conditions are given for the existence of the fuzzy load torque observer and fuzzy speed controller, and the gains of the observer and controller are calculated. The stability of the proposed control system is analytically proven. To validate the effectiveness of the proposed observer-based fuzzy speed controller, the simulation and experimental results are presented. Finally, it is definitely demonstrated that the proposed control algorithm can be used to accurately control the speed of a PM synchronous motor.

본 논문에서는 영구자석 동기전동기(PMSM)의 강인한 속도 제어를 위하여 퍼지 부하 토크관측기와 퍼지 속도제어기를 제안한다. 또한, 퍼지 부하 토크관측기와 퍼지 속도제어기가 존재하기 위한 LMI 조건을 유도하고, 관측기 및 제어기의 이득을 계산한다. 제안된 제어시스템의 안정도가 보장됨을 해석적으로 증명한다. 본 연구에서 제안된 관측기 기반의 퍼지 속도제어기의 성능을 검증하기 위하여, 시뮬레이션 및 실험 결과가 주어졌다. 본 결과를 통하여 제안된 제어 알고리즘은 영구자석 동기전동기의 속도를 정확하게 제어할 수 있음을 검증하였다.
