Abstract

In this paper, recently, it is described to the piezoelectric transformer technology develops, because it was have to favorable characteristics such as electromagnetic-noise free, compact size, higher efficiency, and superior power density, flux linkage, noiseless, etc. its resonance frequency was used to output waveform of a sine wave. A rotor speed identification method of induction motor based on the theory of flux model reference adaptive system(FMRAS). The estimator execute the rotor speed identification so that the vector control of the induction motor may be achieved. The improved auxiliary variable of the model are introduced to perform accurate rotor speed estimation. The control system is composed of the PI controller for speed control and the current controller using space voltage vector PWM techniuqe and DC-DC converter. High speed calculation and processing for vector control is carried out by digital signal one chip microprocessor. Validity of the proposed control method is verified through simulation and experimental results.

본 논문에서는 최근, 압전 변압기 기술의 급속한 발전을 이용하므로 자계의 잡음이 없고, 크기가 소형화되며 고효율과 고 전력 밀도, 누설자속이 없어 노이즈 발생이 없고, 공진주파수만을 이용하므로 출력파형이 정현파에 가까워 고조파 잡음이 없는 점을 이용하여 전기적인 등가회로를 적용하여 DC-DC 컨버터를 구현 하였다. 유도전동기 회전자 속도 개념에 자속 기준 모델 적용 시스템(FMRAS)을 적용하였다. 유도전동기의 벡터제어는 회전자 속도 정의의 추정값을 이용하여 실행 할 수 있고, 부가된 변화되는 모델로 회전자 목표값 계산을 수행 할 수 있다. 이 시스템은 PWM 공간 전압기법과 DC-DC 컨버터를 이용하여 벡터전류제어와 속도제어를 위한 PI제어기로 구성되어 있다. 제어를 위한 실행과 높은 속도계산을 디지털 신호 원칩 마이크로프로세서에 의해 수행 되었고, 시뮬레이션과 실험을 통해서 다양한 제어 방법의 타당성을 제시 하였다.
