Abstract
The optimal design of a passive, mass-spring-damper device to attenuate the coning motion of non-rigid, spinning spacecraft under thrust is investigated. Both one-dimensional and two-dimensional mass motions in a plane that is perpendicular to the thrust/spin axis are considered. The optimal location of a one-dimensional device is determined without making use of earlier approximations on inertia ratio. Necessary and sufficient conditions for asymptotic stability are presented in terms of fundamental system properties. These conditions are interpreted in view of the physical system dynamics. Results are presented from attempts to perform constrained optimization of the two-dimensional device. Performance is compared with a similar device that is constrained to one-dimensional motion.
