Abstract:

This report presents the final technical results of the TRW Vibration Control of Space Structures VCOSS program. Subtasks include 1 Dynamic performance studies of a vibration controlled structure, 2 Design iterations, 3 Graphic representation of system performance LOS errors, 4 Comparison of active controlled to stiffness controlled model. During this phase an emphasis was placed on development of control hardware and its impact on spacecraft power and weight budgets. A preliminary estimate of the implementation costs associated with the chosen design was also made. An evaluation of the selected hardware is presented. It was determined that mission requirements could be met and that the hardware necessary to achieve these requirements is essentially existing and the state of the art in nature. Based on the presented comparison between the active and the stiffness controlled models, it appears that there is a substantial payoff in active control. Author
