Efficient Eigenvalue Assignment for Large Space Structures

A novel and efficient approach for the eigenvalue assignment of large, first-order, time-invariant systems is developed using full-state feedback and output feedback. The full-state feedback approach basically consists of three steps. First, a Schur decomposition is applied to triangularize the state matrix. Second, a series of coordinate rotations (Givens rotations) is used to move the eigenva...

Uncertainty Modeling and Experiments in Control of Large Flexible Space Structures

Approaches to uncertainty modeling for robust control of large flexible space structures (LFSS’s) such as additive or multiplicative perturbations in H1 do not work very well because of the special properties of LFSS dynamics. In this paper, we propose the use of a left-coprime factorization (LCF) of LFSS dynamics in modal coordinates in order to get improved stability margins and performance i...

Large Scale Experiments Data Analysis for Estimation of Hydrodynamic Force Coefficients

This paper describes the various frequency domain methods which may be used to analyze experiments data on the force experienced by a circular cylinder in wave and current to estimate drag and inertia coefficients for use in Morison’s equation. An additional approach, system identification techniques (SIT) is also introduced. A set of data obtained from experiments on heavily roughened circular...

Large Scale Experiments Data Analysis for Estimation of Hydrodynamic Force Coefficients Part 1: Time Domain Analysis

This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...

Polymer Composite Reliability Requirements for Large Space Structures

Long-life (10-30 years) large space structures are considered by NASA for a number of future earthorbiting missions. The use of very thin graphite-fiber composites have been considered as structural m~terials for the fabr~cation o~ these structures. A combination of analytical and experimental approaches w1ll be needed to prov1de a rel1able data base on engineering properties of these materials...
