Date of Defense 1997-04-21 Availability unrestricted AbstractFlutter suppression is a problem of
considerable interest in modern avionics. Flutter
is a vibration caused by energy in the airstream
being absorbed by a non-rigid wing. Active
control is one possible method of suppressing
flutter. However, due to unmeasurable
aerodynamic-lag states, developing an active
control using full-state feedback is not viable.
The use of a state-estimator is a more practical
way of developing active controllers. In this
paper we investigate two control methods using
state-estimators. We also use simple models of
disturbances to test attenuation and robustness
of each control method. Finally, a method of
quantitative robust analysis is reviewed and then
applied to each of the controlled systems.
