Abstract

A new three-axis interface system called “decoupling mechanism” is described. Dynamic equations are simple derived which indicate spacecraft with decoupling mechanism is a descriptor system. Eigenvalue mobility is utilized to measure controllability for large flexible spacecraft with the new system. Analysis is performed for descriptor decentralized control system. These comparisons between two kinds of system provide physical insight on the improvement introduced by proposed mechanism.
