Abstract :
In this paper the attitude tracking problem is solved for a flexible spacecraft in the case of measurements of the variables describing the altitude error. Such a control could be applied in tolerance of the spacecraft control system and the success of the mission. The result is a dynamic controller capable of reconstructing the information regarding the spacecraft angular velocity and those regarding the modal variables, describing the dynamics of the flexible appendages present in the spacecraft.
