Optimization issues in the design and control of large space structures : proceedings of the session

The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different types of parameters for parameter estimation based on actual test data. The approximation of multivariable control system performance by the redesign of structures for reduced dynamic response is also studied. A third study shows that by designing a structure based on an optimality criterion approach the dynamic characteristics of a closed-loop system or a large space structure can be improved. The final paper emphasizes the need to account for geometric and material nonlinearities in actively controlling highly flexible large space structures.
