             abstract = "The design of the satellite Attitude Control System (ACS) becomes 
                         more complex when the satellite structure has different type of 
                         components like, flexible solar panels, antennas, mechanical 
                         manipulators and tanks with fuel, since the ACS performance and 
                         robustness will depend if the dynamics interaction effects between 
                         these components are considered in the satellite controller 
                         design. A crucial interaction can occur between the fuel slosh 
                         motion and the satellite rigid motion during translational and/or 
                         rotational manoeuvre since these interactions can change the 
                         satellite center of mass position damaging the ACS pointing 
                         accuracy. Although, a well-designed controller can suppress such 
                         disturbances quickly, the controller error pointing may be limited 
                         by the minimum time necessary to suppress such disturbances 
                         affecting thus the satellite attitude acquisition. It is known 
                         that one way to minimize such problems is to design controllers 
                         with a bandwidth below the lowest slosh and/or vibration mode 
                         which can result in slow maneuvers inconsistent with the space 
                         mission requirements. As a result, the design of the satellite 
                         controller needs to explore the limits between the conflicting 
                         requirements of performance and robustness. This paper 
                         investigates the effects of the interaction between the liquid 
                         motion (slosh) and the flexibility in the satellite dynamics in 
                         order to predict what the damage to the LQR and LQG controller 
                         performance and robustness.",
