초록

위성 탑재체의 지향성능을 향상시키기 위하여 반수동 진동제어법을 제안하고, 시뮬레이션에 의해 진동절연 효과를 검증하였다. 본 논문에서 제안한 반수동 진동제어법은 고주파수 영역에서의 저댐핑 수동제어와, 구조물의 공진을 포함하는 저주파수 영역에서의 고댐핑 수동제어가 갖는 진동절연 효과를 동시에 만족시키기 위해 고안되었다. 시뮬레이션 결과는 반수동 진동제어법이 상기의 효과를 구현하는데 있어 효과적임을 나타낸다.

A semi-passive vibration isolation control method for enhancing pointing performance of on-board payload has been derived, and its effectiveness has been evaluated through numerical simulation. The semi-passive control law proposed in this study was derived so as to obtain the same performance as a high passive damping at low frequencies and obtain the same performance as a passive low damping at high frequencies. In the numerical simulation, the intended vibration isolation performance of the semi-passive control law has been obtained.
