A Structural Dynamics Approach to the Simulation of Spacecraft Control/Structure Interaction

Author and Affiliation:
Young, J. W.(Structural Dynamics Research Corp., San Diego, CA, United States)
Abstract: A relatively simple approach to the analysis of linear spacecraft control/structure interaction problems is presented. The approach uses a commercially available structural system dynamic analysis package for both controller and plant dynamics, thus obviating the need to transfer data between separate programs. The unilateral coupling between components in the control system block diagram is simulated using sparse matrix stiffness and damping elements available in the structural dynamic code. The approach is illustrated with a series of simple tutorial examples of a rigid spacecraft core with flexible appendages.
