| Résumé : | This paper considers the stabilization of the neglected dynamics of the higher modes of vibration in the context of the linear-quadratic-Gaussian controller design. The approach consists of designing observers by directly optimizing a combined cost of spillover margin and standard quadratic performance. Two formulations are proposed. The first optimizes the noise statistics used in the design of the Kalman-Bucy reduced state estimator, and the second optimizes directly the observer gain matrix. A singular value stability robustness test is used to identify the potentially unstable modes. The proposed method can start from an unstable controller and stabilize it through numerical optimization. © 1990 American Institute of Aeronautics and Astronautics, Inc., All rights reserved. |
