             abstract = "In the design of the Attitude Control System (ACS) for a 
                         Rigid-flexible Satellite (RFS) it is important to take into 
                         account the influence of the structure's flexibility, since its 
                         interaction with the satellite rigid motion during translational 
                         and/or rotational maneuver, can damage the ACS pointing accuracy. 
                         In the linearization and/or reduction of the RFS mathematic model, 
                         usually one loses some important information associated with the 
                         satellite true dynamical behavior. One way to recovery this 
                         information is to include in the ACS design the parametric and non 
                         parametric uncertainties of the system. The H infinity control 
                         methodology is able to take into account the parametric 
                         uncertainty in the control law design so as the controller becomes 
                         more robust. This paper presents the design of a robust controller 
                         using the H infinity control technique to control the attitude of 
                         a RFS which is represented by a flexible beam connected to a 
                         central rigid hub considering the set of parametric uncertainty. 
                         The results of the simulations have shown that the control law 
                         designed with the H-infinity control method was robust enough to 
                         support the action of uncertainties and control the RFS attitude 
                         and suppress its panel's vibrations.",
