Abstract
The present invention provides a method for refined attitude control based on output feedback for a flexible spacecraft. The control method comprises the following steps of: a) building a flexible spacecraft dynamical system Σ, converting the flexible spacecraft dynamical system Σinto a flexible spacecraft dynamical system Σ, and incorporating spacecraft rigid-flexible coupling dynamic disturbance into the flexible spacecraft dynamical system Σ; b) constructing an external system Σ, and describing the rigid-flexible coupling dynamic disturbance through the external system Σ; c) configuring a disturbance observer for estimating the value of the rigid-flexible coupling dynamic disturbance; d) configuring a dynamic output feedback Hcontroller; e) compounding the disturbance observer in step c) with the dynamic output feedback Hcontroller in step d) to obtain a flexible spacecraft refined attitude control system Σ; the flexible spacecraft refined attitude control system Σcompensating for the rigid-flexible coupling dynamic disturbance through the estimated value.
