Vibration Control of Space Structures VCOSS A: High and Low-Authority Hardware Implementations

摘要

The report considers some hardware aspects of large space structure control implementations. Hardware and system performance requirements are overviewed, principally in the context of vibration suppression. Analytical models based on soft and stiff versions of CSDL (Charles Stark Draper Lab.) no. 2 structure are used to evaluate vibration suppression performance for actively controlled and passive structures. The effects of hardware bandwidth limitations and system modeling errors are evaluated for the active controls case. It is shown that hardware bandwidth limitations do not pose significant control design problems. The basic elements for a hardware demonstration program to evaluate these results is given.
