Optimized Stator Flux Oriented Control of IM using Adaptive Speed Estimator

적응 속도추정기를 이용한 유도전동기의 최적 고정자 자속 기준제어

For high performance ac drives, the speed sensorless vector control and the stator flux orientation concept have received increasing attention. This paper presents a new method of estimation the speed of AC induction machine(IM). To improve the speed estimation characteristics, accurate stator resistance variation is considered. The effectiveness of the proposed method is verified computer simulation.
