Book Description
This report summarizes the research performed on adaptive control techniques for Large Space Structures (LSS). The research effort concentrated on two areas: (1) on-line robust design from identified models - what is referred to here as adaptive calibration; and (2) an analysis of slow-adaptation for adaptive control of LSS. The report summarizes the results obtained in theses areas and also includes Appendices which contain technical articles: (1) Adaptive Control of Large Space Structures; (2) Adaptive Control Via Finite Modeling and Robust Control; (3) On the use of the Method of Averaging for the Stability analysis of Adaptive Linear Control Systems; and (4) Conditions for the Convergence and Divergence of Parameter Adaptive Linear Systems.

Book Description
The purpose of this thesis is to apply moving-bank multiple model adaptive estimation and control (MMAE/MMAC) algorithms to an actual space structure (SPICE) being examined at Phillips Laboratory at Kirtland AFB, NM. The structure consists of a large platform and a smaller platform connected by three legs in a tripod fashion. Kalman filtering and LQG control techniques are utilized as the primary design tool. Implementing a bank of filters increases the robustness of the LQG controller when uncertainties exist in the system model, whereas the moving bank is utilized to reduce the computational load. Several reduced-order models are developed from the truth model using modal analysis and modal cost analysis. The MMAE/MMAC design with a dramatically reduced-order filter model provides an excellent method to estimate a wide range of parameter variations and to quell oscillations in the structure.
