Abstract

The accuracy of motor parameter measurement is necessary to improve the performance of vector control of an induction motor. The rotor time constant affects the performance of controller and also the resistance and leakage inductance of stator are very important design parameters of current and speed controller. In this paper a new modified motor parameter measurement methods for high performance speed control of vector control of an induction motor are proposed.

유도전동기의 고성능 속도 제어를 위해서는 전동기 정수의 정확한 측정이 필요하다. 특히 전동기의 토크 제어를 위해 사용되는 벡터 제어의 경우 회전자 저항과 인덕턴스의 항으로 주어지는 시정수는 제어기의 성능에 큰 영향을 준다. 또한 고정자 저항과 누설 인덕턴스는 전류제어기와 속도 제어기의 이득을 구하고 설계하는 중요한 변수가 된다. 본 논문에서는 기존의 정수 측정 방법을 수정 보완한 새로운 유도 전동기 정수 측정방법을 제시한다.
