This paper investigates the attitude stability of a flexible spacecraft made of a rigid platform and multiple flexible appendages during retargeting rest to rest slew maneuver. In addition to the attenuation of external disturbances and model uncertainties, the designed fuzzy controller goal is to suppress the vibration caused by the minimum time manoeuver of the appendages, and to stabilize the attitude of the spacecraft subject to independent time delay and actuators saturation. The fuzzy controller-observer is formulated as a set of linear matrix inequalities and utilizes the parallel distributed compensator to obtain the feedback control and the observer gains. Numerical simulations are provided to measure the performance of the proposed controller.
