THE NASA-LARC CONTROLS-STRUCTURES INTERACTION (CSI) TECHNOLOGY PROGRAM

The integration of active control systems for controlling the structur al dynamics of flexible spacecraft can significantly benefit performan ce. Recognizing the potential improvement for future spacecraft, NASA has an ongoing Controls-Structures Interaction (CSI) technology progra m whose objective is to develop and validate the technology needed to integrate active control systems and flexible structures to meet the r equirements of future space missions. The purpose of this paper is to describe the ongoing CSI activities at the LaRC.
