冗長なRWを搭載した宇宙機の時変の角速度目標に対する 姿勢制御とアンローディング

抄録

We applied the LPV (Linear Parameter-Varying) control theory to attitude control for spacecraft. With this method, control stability and control performance can be considered at the same time. This method was applied to attitude tracking problems. In this paper, a method to apply the LPV control theory to the tracking problem of the attitude as well as the angular velocity. We focus on spacecraft with multiple RWs (Reaction Wheels). Using the redundancy, an unloading method for the RWs is also described. Numerical simulations assumed a spacecraft with four RWs are conducted to compare the tracking error by the proposed method and by a Lyapunov-based control.
