Output Regulation of a Flexible Spacecraft with Exponentially Stable/Unstable Internal Dynamics

摘要

In this paper, non-linear output regulation of a flexible spacecraft with either exponentially stable or unstable internal dynamics is analysed. The system considered is composed of a main body, where a control torque is applied, an a flexible boom which supports, through an actuated spherical joint, an antenna. The system outputs are the attitudes of the main body and the antenna, which are required to exponentially track given desired trajectories.
