Active damping of modal oscillation is critical to the
success of future versions of Space Station Freedom.
Vibratory motion may be induced by external disturbances such
as solar and gravity gradient torques, extra vehicular and
experimental activity, aerodynamic forces, the earth's
magnetic field, and space shuttle docking. Linear proof mass
actuators can provide control on the space station to achieve
this damping effect. Two control algorithms, Linear Quadratic
Gaussian control and H∞ control are applied to a model of
Space Station Freedom. The results compare the robustness,
stability, and performance of the Space Station under the
effects of each of the two control algorithms.
