Dynamics and Robust Control of Sampled Data Systems for Large Space Structures

Abstract

The objective of this research is to develop practical design procedures that can be used in conjunction with optimal digital controllers for future orbiting large space structural systems. In practice, the observational data used to verify the orientation and shape of large flexible systems will, in general, be collected on a sampled basis (discrete-time data system). The system is assumed to be completely observable and deterministic. Systems which will be designed to control both the overall orientation as well as the shape of some of the subsystems (such as antenna mesh form) must function in the discrete-time domain. The aim of this research is to develop methods that can be used to design linear quadratic regulator (LQR) controllers for orbiting large flexible systems. The digital control of an orbiting thin square plate system is analyzed in this volume of the final report....
