テザー型宇宙太陽発電衛星の発電効率を考慮した姿勢制御

摘要

This paper is devoted to analyze dynamical behavior of a tethered Space Solar Power Satellite (SSPS) system proposed bythe Institute for Unmanned Space Experiment Free Flyer (USEF). The system consists of a large thin and flexible rectanglesolar panel connected to a bus system through tethers. Attitude of the tethered SSPS is gravity-gradient stabilized byemployment of tether technology. Control method is studied for the attitude of the solar panel, which is controlled to orienttoward solar light in order to improve the efficient generation of electric power. The controlled performance is analyzednumerically and the results show efficient performance of the tethered SSPS for the generation of sufficient electric power.
