비례 & 적분 보상기를 갖는 영구자석 동기전동기의 V/f 제어

초록

This paper proposes a sensorless V/f control method of surface mounted permanent magnet synchronous motor without a brake winding. Arithmetic computation is simpler than the common vector control, and the lower a cost price, dynamics and stability is guaranteed. When the loss of synchronous occurs with the load disturbances, both proportional compensator and integral compensator is applied to quickly and accurately to improve the speed error.
