Abstract

In position detection for super speed maglev propulsion control, the influence of position signal delay and transmit cycle on propulsion power degradation is investigated analytically and validated by test bed experiments. As a solution to the problem caused by signal transmit, position signal compensation and estimation method is proposed and applied to the test bed. Through experiments, it is confirmed that by adapting the proposed method, the propulsion power is increased remarkably, which results in acceleration and velocity performance improvement. This method could be effectively applied to position detection system of Korean super speed maglev which is under development.

본 논문에서는 초고속 자기부상철도 추진 제어에 필수적인 차량의 위치검지에 있어서 위치신호 송신지연 및 송신주기가 추력에 미치는 영향을 수치적으로 분석하고 test bed를 이용한 실험을 통해 이를 확인하였다. 위치신호 송신문제를 해결하기 위한 방안으로서 위치신호 보상 및 추정 기법을 제시하였으며 제시된 방법을 test bed에 적용하여 효용성을 검증하였다. 적용 결과 추력이 크게 증가하였으며 이에 따라 차량의 가속도 및 속도 성능이 향상됨을 확인하였다. 본 방법은 향후 개발 예정인 한국형 초고속 자기부상철도의 위치검지시스템에 효과적으로 사용될 수 있을 것으로 판단된다.
