Research Summary
  • Korean
  • 본 논문은 적응 출력조절기 관한 연구결과이다. 이것은 주파수 적응의 기능이 있는 Add-on 형태의 출력 조절기이다. 내부 모델 원리에 근거한 주파수 적응 앨고리즘이 정현파 형태 외란의 주파수를 검증한다. 이 결과는 이전에 발표된 출력조절기 연구결과의 확장이다. Brown이 사용한 적응 앨고리즘과 다른 내부모델을 사용하였다. 다른 형태의 출력조절기 형태를 사용함으로써 DC 성분의 바이어스가 존재하더라도 주파수를 검증할 수 있도록 설계되었다. 이 방법을 사용함으로써 compact set에 있는 주파수는 검증이 가능함을 보였다. 주파수가 시간 공간상에서 느리게 변화하는 한 전체 안정도가 보장됨을 보였다. 제안된 제어기의 성능은 유효성을 모의실험과 실제실험을 통하여 보였다. 실험과 모의실험 결과가 잘 일치함을 확인하였다.

  • This paper presents an adaptive output regulator. It is an add-on type output regulator with frequency adaptation algorithm. A frequency adaptation algorithm based on internal model principle is used to identify frequency of sinusoidal disturbance. This result is an extension of the previous work for output regulator. Brown's adaptive algorithm was modified with a different internal model so that the algorithm can estimate frequency of sinusoidal disturbance with bias term. By adding the adaptive algorithm to add-on output regulator, the output regulator is able to reject disturbance even though its bias and frequency are unknown. It was shown that the proposed method is stable for frequencies within a connected compact set. In addition, its stability was proven under the assumption that the frequency of disturbance varies slowly in time. The performance of the proposed method is verified with simulation and experimental results. There is a good agreement between simulation and experimental results.

  • Abstract
  • This paper presents an adaptive output regulator. It is an add-on type output regulator with frequency adaptation algorithm. A frequency adaptation algorithm based on internal model principle is used to identify frequency of sinusoidal disturbance. It is shown that the proposed method is stable for
    frequency within a connected compact set. Its stability is proven under the assumption that the frequency of disturbance varies slowly in time. The performance of the proposed method is verified with simulation and experimental results. There is a good agreement between simulation and experimental results.
  • Research result and Utilization method
  • In this paper, an adaptive output regulator was proposed for cancelling biased sinusoidal disturbances with unknown bias, magnitude, phase and frequency. This result is an extension of the previous work for output regulator. Brown's adaptive algorithm was modified with a different internal model so that the algorithm can estimate frequency of sinusoidal disturbance with bias term. By adding the adaptive algorithm to add-on output regulator, the output regulator is able to reject disturbance even though its
    bias and frequency are unknown. It was shown that the proposed method is stable for frequencies within a connected compact set. In addition, its stability was proven under the assumption that the frequency of disturbance varies slowly in time.
