Modeling and Computational Algorithms for Parameter Estimation and Optimal Control of Aeroelastic Systems and Large Flexible Structures.

Abstract

The goal of this research is to developed computational algorithms for identifications and control, especially with application to aeroelastic and viscoelastic systems. The research has emphasized developement of Chandresekhar algorithms for optimal control of distributed systems and state models and computational algorithms for aeroelastic control systems. During this period, the investigators developed fast algorithms for the general linear quadratic optimal control problems for functional differential equations using Chandresekhar factorization techniques. The resulting algorithms show improved rates of convergence over Ricatti techniques and for certain large problems is the only algorithms which was shown to converge in practice. Nine publications were produced during this period under this grant, including Factorization and Reduction Methods for Optimal Control of Hereditary Systems and Modeling and Approximation for a Ciscoelastic Control Problem.
