Abstract
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.
