Control of Flexible Structures: Model Errors, Robustness Measures, and Optimization of Feedback Controllers

摘要

This report summarizes new methods for flexible structures' dynamic analysis, system identification, and maneuver controls. New control design methods are introduced for considering several competing performance measures simultaneously. A new attitude control method using single gimbal control moment gyros is introduced. New results and insights on singularity avoidance are presented. A method is given for simultaneous optimization of structural design parameters and feedback controller. Keywords include: Active Control, Structural Analysis, Spacecraft maneuvers, Robust control. (RH)
