Abstract

The spillover modes of a large flexible structure with high modal density can be stabilized by residual-mode filtering, as is presently illustrated for a reduced-order model of the Passive and Active Control of Space Structures program's Dynamic Test Article by means of an estimator and regulator that were developed via linear Quadratin Gaussian and loop-transfer recovery methods. The implementation of this controller on the full-order system generated spillover instabilities; the residual-mode filter was added to the control system without modification of the original controller, and stabilization was achieved.
