摘要

A procedure for designing command profiles for flexible spacecraft is presented. The command profiles are required to accelerate the spacecraft to a constant velocity or move the spacecraft from rest to rest with very little residual vibration, even in the presence of modeling errors. To model the case where the 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 significantly more insensitive to modeling errors or parameter variations than those previously reported. The control technique is verified with both computer simulations and hardware experiments.
