New Space Structure and Control Design Concepts.

Abstract

The objective of this research is to develop a technique to integrate structure and control design with applications to the Phillips Lab Laser Crosslink Structure (LCS). This structure acts as a mounting frame for a proposed laser based communications system attached to a DSP surveillance satellite; the laser system is part of a planned upgrade, from the radio based system currently employed. Since the laser based communications system is about ten times more sensitive to transmitter/receiver line of sight errors than the current communications system, an active vibration control system is necessary. The goal of this investigation is to redesign the LCS and an appropriate controller simultaneously so that the vibration imparted to the structure by the satellite is compensated for by the control system, thus facilitating communications.
