Abstract
2-체널 링-코어 프럭스-게이트 콤파스(Two-Channel Ring-Core Flux-Gate Compass; TCRC FG-Compass)의 성능평가 시스템 설계와 구현방법 및, 다항회귀 모형 기반의 평가 절차와 방법을 기술했다. 성능평가 시스템은 스템모터 구동 유닛과, 방위정보 전송 유닛, 다항회귀식에 의한 평가 프로그램 등으로 구성하였다. 성능평가 실험결과, TCRC FG-Compass는 잔차가 <TEX>$2^{\circ}$</TEX>인 반면, 기존의 FG-Compass는 잔차가 <TEX>$4^{\circ}$</TEX>임을 나타냈다. 따라서 성능이 향상된 새로운 FG-Compass 설계가 가능함을 확인하였다. 또한, 자동으로 잔차를 추정하고 보정할 수 있는 설계론에 관해서도 논의하였다. Design and implementation methodologies on the performance evaluation system of Two-Channel Ring-Core Flux-Gate Compass (TCRC FG-Compass) are described, with evaluation procedures and methods based on the polynomial regression models. Performance evaluation system consists of a step motor driving unit, a bearing transmitting unit and evaluation programs derived from polynomial regression formulae. Newly designed performance evaluation system enabled the accuracy of TCRC FG-Compass to be ascertained. It was confirmed that the size of residual deviation of TCRC FG-Compass is <TEX>$2^{\circ}$</TEX>, while that of the conventional one is <TEX>$4^{\circ}$</TEX>. In addition, the design methodology to the self estimation and correction of residual deviations is also discussed.
