Abstract
The inherent difficulties of the conventional spacecraft design, which first considered the optimization with respect to structural variables and then with respect to control variables, have led to the concept of Controls-Structures Interactive Design. The success of the CSI design of Space structures without articulated appendages has prompted the extension of the CSI design to systems with articulated appendages. The presentation is of two parts, the first part deals with the derivations of the equations of motion and the second part deals with the eigenvalue/vector approximations.
Three approaches, namely: the multibody approach, the finite element based approach with hinge joints and an alternative approach which enables the distinction of rigid body components from the flexible body components in an eigenvector, will be discussed. The validity of the approaches is achieved by comparing the results of various approaches.
In case of the space structures with articulated appendages there is no definite operating configuration to perform the CSI analysis of these systems, the analysis should be performed at various configurations. The higher order eigenvalue/vector sensitivity derivatives with respect to the changes in the orientation of the appendage have been derived. Using the fourth order Taylor's series expression, the eigenvalues/vectors for a wide range of configurations of Space Structures with articulated appendages are being approximated.
