Control of Flexible Structures

Authors: J. A. Burns; E. M. Cliff; H. J. Kelley; F. H. Lutze; R. E. Miller; OPTIMIZATION INC BLACKSBURG VA
Abstract:
This report summarizes the work done under contract FO 4611-86-C- 0008. The principal goals were to develop state-space models and computational algorithms for control of beam and plate type structures, and, more generally, to increase the understanding of the basic problems associated with this development. The state-space approach is based on a distributed parameter model of the structure that includes the fundamental equations without modal truncation. The approach is to use basic physical principles to write down the governing partial differential equations, construct a state-space model from these governing equations, formulate the optimal control problem in terms of the state-space model, develop a convergent approximation scheme and conduct numerical experiments to test the method. Flexible structures, Active control, Distributed-parameter systems. (jes)
