Selection Criteria of Component Synthesis Vibration Suppression Mode Order for Spacecraft Attitude Maneuver with Reaction Jet Actuators.

Aiming at the problem of Component force Synthesis Vibration Suppression( CSVS) by using the jet actuator to realize attitude maneuver, and taking the expected attitude pointing accuracy and stability as constraint conditions, a selection criteria is proposed to select some orders of the system vibration mode which indeed need to suppress. The- simulation test model is consist of the center rigid body rotated around a single axis and flexible accessories, the Lagrange method is used to establish dynamics equations applicable to different positions of attachment, then the selection criteria is applied to design constant amplitude component synthesis control moment. Simulation results prove that the selection criteria is effective, and if the flexible accessories are adjusted to an appropriate position before attitude maneuver, the control design is more simple, and easier to gain higher attitude accuracy and stability, as well has the advantages of jet fewer.
