Abstract: Through input-output decomposition of structured parameter uncertainties of the controlled plant, the robust control problem of space station attitude system with parameter uncertainties is converted to a conventional disturbance rejection H∞ controller design problem, then a full-state feedback H∞ robust controller is formulated, which can be solved using the Glover-Doyle algorithm. The proposed method was applied to the attitude control/momentum management (ACMM) system of a space station, and two kinds of parameter uncertainties which appear most frequently in spacecraft engineering were considered. Simulation results showed efficiency of the given method.
