This report describes the preliminary studies for the on-orbit system identification and attitude control experiments for ETS-8 (Engineering Test Satellite-8). ETS-8 is an advanced satellite being developed primarily to establish and verify the world's largest 3-ton-class geostationary satellite bus technology and will be launched by H-2A launch vehicle in a couple of years. The on-orbit system identification and attitude control experimental program is in the planning phase. In this report, the dynamics model of ETS-8, and the mathematical background of the on-orbit system identification algorithms are presented. In addition the gain-scheduling robust controller design method, which is applicable to the parameter-variation model, is also described.
