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
