Abstract

Real parameter uncertainty and phase information play a key role in the analysis and synthesis of robust controllers for lightly damped flexible structures. The purpose of this study is to examine the impact of these issues on structural control, their interrelationship, and their manifestation within the analysis and synthesis of feedback systems. The discussion is illustrated by examining robust controllers designed for the ACES structure at Marshall Space Flight Center. These controllers were designed by means of the maximum entropy generalized linear quadratic Gaussian methodology
