This paper considers robust stabilization of large space structures (LSS) against dynamic uncertainty. Generally, mathematical models for control system design of LSS are low-dimensional ones, which represent low frequency characteristics of the structures. Therefore, if neglected vibration modes in high frequency range are excited by disturbances such as solar radiation, dynamic characteristics may not be desirable. To solve this problem, an approximated DVDFB has been proposed. In this paper, we show that the decentralized approximated DVDFB makes the closed-loop system an optimal regulator for a frequency dependent quadratic cost function, and we also show a numerical example in which the proposed method stabilizes the overall closed-loop system robustly against dynamic uncertainty.
