| Abstract: | A low order mathematical model for a class of flexible multibody spacecraft is obtained by hybrid coordinate and component mode synthesis. The generic spacecraft considered consists of a main rigid body to which a number of flexible muhibody appendages are attached. The model and flexible coupling coefficients developed can be used for analysis and simulation of many realistic spacecrafts. The model is low-order and adapts to control system design for this kind of variable structure spacecraft. |
