Abstract

In this paper, we propose a motion chair for flight simulators that can be precisely controlled using an FPGA. Existing motion chairs are unsuitable for a flight simulator environment, where natural position changes occur due to a sense of disconnection arising from simple mechanical motor operations. This paper, presents a motion chair suitable for flight simulation through BLDC motor control through the FPGA module. In addition, the operating load was improved by controlling the drive shaft and control device of the motion chair as a single driver. As a result of comparing the control signal and feedback data to evaluate the performance of the implemented system, it was confirmed that the change was stable without error in the target position, and the high-speed camera showed a natural flowing state change suitable for flight simulation. In the future, we plan to develop it into an integrated flight motion platform linked to virtual reality hardware.

본 논문에서는 FPGA를 이용하여 정밀제어가 가능한 비행 시뮬레이터용 모션 체어를 제안한다. 기존 모션 체어는 단순 기계식 모터 동작에서 발생하는 단절감으로 인하여 자연스러운 위치 변화가 발생하는 비행 시뮬레이터 환경에서는 적합성이 낮은 문제점을 가진다. 본 논문에서는 FPGA 모듈을 통한 BLDC 모터 제어를 통하여 비행 시뮬레이션에 적합한 모션 체어를 제시한다. 또한, 모션 체어의 구동축과 조종 장치를 단일 드라이브로 제어하여 동작 부하를 개선하였다. 구현된 시스템의 성능평가를 위하여 제어 신호와 피드백 데이터를 비교한 결과, 목표 위치까지의 오차 없이 안정적으로 변화하는 것을 확인하였고 고속 카메라를 통하여 비행 시뮬레이션에 적합한 자연스러운 유영적인 상태 변화를 보였다. 향후, 가상현실 하드웨어와 연동한 통합 비행 모션 플랫폼으로 발전시키고자 한다.
