Abstract
For many years, the importance of active feedback control of large space structure (LSS) have been widely recognized. This paper presents results on studying the attitude control problem for an LSS typified by the ETSVI (Engineering Test Satellite-VI) spececraft. The attitude control system based on the statefeedback control is proposed. The control law is designed by using the turn over design method. This method, which locates closedloop poles to be in a specified region, has good properties of the optimal regulator and the pole-placement method, so it has excellent vibration supression capability. Moreover, the proposed control method has some desirable robustness properties against modeling uncertainties such as inaccurate identification of natural frequencies and damping ratio and so on. The purpose of this paper is to show the efficiency of the proposed control method by a ground-based test model. The ground-based test model simulates the attitude motion around roll-axis by using a single-axis air-table. The experimental results indicated that the turn-over design method has great promise for used in LSSs.
