유연구조를 갖는 인공위성의 자세제어에 관한 연구

Abstract

In this paper a new LOG method is proposed for attitude control design of flexible satellites. This method. referred to as Frequency-Weighted LQG with Model Error Sensitivity Suppression (FWL/MESS). is derived from Frequency-Weighted LQG(FWL) and Model Error Sensitivity Suppression (MESS) to incorporate the advantages of the two precedent methods. The proposed method is applied to a design example for which an MSC/NASTRAN model of KOREASAT is used. Simulation study is also conducted to compare the controller performance with other design techniques.
