             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. 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 centre 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 thus affecting the satellite attitude 
                         acquisition. 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 
                         satellite dynamics in order to predict what the damage to the 
                         controller performance and robustness is. The fuel slosh dynamics 
                         is modelled by a pendulum which parameters are identified using 
                         the Kalman filter technique. This information is used to design 
                         the satellite controller by the linear quadratic regulator (LQR) 
                         and linear quadratic Gaussian (LQG) methods to perform a planar 
                         manoeuvre assuming thrusters are actuators.  2014 Luiz Carlos
