Abstract
A method and system for calculating a control function for a structural system ( ) that can be used to determine an appropriate control force to apply to an active member ( ) within a stationary member ( ) on the structural system ( ). An active member ( ) and a stationary member ( ) are defined as a two-mass system in which the active member ( ) and the stationary member ( ) move in opposite directions. The stationary member ( ) is mounted to an isolation subsystem ( ) that is composed of six isolators ( ) at multiple degrees of freedom. The isolation subsystem ( ) is softer than the stationary member ( ), active member ( ) and a spacecraft surface ( ) due to a damping element ( ) of the isolation subsystem ( ). The isolation subsystem ( ) is mounted to the spacecraft ( ) and decouples the spacecraft ( ) from the stationary member ( ) and thus the active member ( ). An accurate control force for the active member ( ) can be determined based upon the above structure ( ).
