Development and Evaluation of a Full Flight Envelope Integrated Flight and Vibration Controller

摘要

Developments in active vibration control have shown significant coupling between flight and vibration control systems, which are traditionally designed independently. This coupling results in performance degradation of the vibration controller, particularly during maneuvering flight. This paper uses linear time invariant models with adequate fidelity for predicting vibratory load response to develop an integrated flight and vibration control design to address coupling and improve performance. These integrated controllers are evaluated herein for robustness to changes in flight and loading conditions. The robustness results are then used in the development and evaluation of a full flight envelope integrated flight and vibration controller. This full flight envelope integrated controller is evaluated in a nonlinear simulation using realistic piloted maneuvers.
