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.
