摘要：
A procedure for designing command profiles for flexible spacecraft is presented. The command profiles are designed to maneuver a spacecraft with very little residual vibration, even in the presence of modeling errors. To model the case where a spacecraft is equipped with on-off reaction jets, the command signals are restricted to positive or negative constant-amplitude pulses. The technique results in command profiles that are much more fuel efficient than the time-optimal commands, yet do not incur a significant time penalty. Robustness to modeling errors of both the time-optimal and the fuel-efficient commands are shown to be highly dependent on move distance; however, the fuel-efficient profiles are always as robust as the time-optimal profiles.
