title = "Composite attitude control for flexible spacecrafts with input saturation",
abstract = "We propose a new composite anti-disturbance control approach with guaranteed input saturation. Such a composite control has two hierarchical loops. The vibrations of flexible appendalges are formulated as one type of disturbances with bounded derivative, for which the disturbance-observer-based controller is designed to compensate in the feed-forward loop. Other disturbances originated from space environment, measurement, actuator and un-modeled dynamics, are merged into the second type of disturbance described by a norm bounded variable. H ∞ state-feedback controller is designed to attenuate the merged disturbance. The input saturation of the actuator is also taken into account in the controller design. The concerned problem is simplfied into a robust control problem via solution of linear matrix inequalities. Numerical simulations and comparisons show that by combining the disturbance observer with H ∞ control, the pointing accuracy of flexible spacecrafts can be improved.",
