RESUMO:

This dissertation aims to investigate the attitude control of a satellite, modeled as a rigid body, whose movement is coupled with the slosh effect of the liquid propellant inside, represented by an equivalent mechanical model, in this case, a simple pendulum. The equations of motion are obtained through Lagrangian formalism. The satellite's excitation frequency is assumed far from the resonant frequency. Only small amplitude of oscillation for the pendulum is allowed, so that the free surface of the fluid remains in planar shape without rotation of its nodal diameter. Attitude control is investigated for different volumes of liquid in the tank. The control technique used is the Quadratic Linear Regulator (LQR) and the results are obtained numerically.
