This thesis work focuses on the control of multi-agent systems using graph theory, in particular deals with attitude coordinated control of spacecrafts. A multi-agent system is a dynamical system composed by a finite number of subsystems (agents), each of them is characterized by a set of equations describing its own dynamics. Each agent is also capable of sharing information about its states with the others, for instance displacement or angular velocity. This overall behaviour can be represented by a graph. The agents are considered to be governed by Newton‘s law for rotations, coupled with a flexible dynamics equation that models the possible presence of flexible parts attached to the rigid body of the spacecraft.
