The objective of ACOSS is to develop and demonstrate the technology required to suppress vibrational disturbances damping augmentation and elastic mode control of large space structures so that they can meet the required line- of-sight and jitter control requirements. In this effort a control methodology is developed for disturbance rejection and an analysis is done for a sample surveillance structure, ACOSS-2. The work includes looking at robustness and assessing system identification methods. The theory is being applied to several bench top brassboards and these experiments are reported in detail. A proof-of- concept experiment will be conducted at RF tolerances and this five meter structure is reported on.
