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 maneuver 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 flexible satellite dynamics in order to
predict what the damage to the controller performance and
robustness is. The fuel slosh dynamics is modeled using its
pendulum analogs mechanical system which parameters are identified
using the Kalman filter technique. This information is used to
designs and to compare the satellite attitude control system by
the Linear Quadratic Gaussian (LQG) and Hinfinity methods.",
