Estimation and Control of Distributed Models for Certain Elastic Systems Arising in Large Space Structures.

Abstract

During the reporting period progress was made toward the goal of developing efficient and accurate estimation and control algorithms for elastic structures composed of beams and plates. Specifically, results were obtained that determine necessary and sufficient conditions for uniqueness in discrete versions of second order elliptic estimation of elastic coefficients for static and dynamic models of beams and plates, the control of the shape of static beams and plates by means of actuators of small support, and the optimal placement of actuators to control the shape of beams and plates. These efforts have produced computer codes on which experimentation is currently being conducted to test methods and algorithms. (Author)
