Abstract

Controller-structure interaction (CSI) affects the stability margin of actively-controlled large flexible structures, degrading performance to the point where instability is generated. Perturbation theory is presently employed to identify those structural modes that are affected by CSI, in order that they be filtered out of the controller's path. Numerical results are presented for the cases of a simply-supported beam, a space-based laser, and a truss beam.
