Modeling and Control of Flexible Structures.

Abstract

This report focuses on the roles of models of flexible structures in the design and evaluation of control laws for the damping of vibrational motions in those structures. The first section discusses a generic class of continuum models for flexible structures describing the abstract mathematical formulation of the models as a framework for the design of control laws. The second section shows how direct frequency domain designs for control laws may be achieved for this class of models based on a spectral factorization procedure which replaces the usual computation of Riccati equations. The third section, examines the problem of deriving transfer function representations of the structural models as required in the frequency domain design procedure. Section four describes an analytical procedure for the derivation of continuum models for large scale structures with a regular infrastucture.
