摘要

Unsymmetric flexible spacecrafts have particular dynamic characteristics; when the attitude control actuactor such as RCS thruster is used, the imbalance between negative torque and positive torque is caused. And even worse, an inertia matrix and a coupling matrix are changed depending on the displacement of the rotation paddle and the mobile sensor. In this paper, an attitude control system with consideration of these characteristics is proposed.
