Control Design for Evolutionary Structural Systems.

Abstract

This report summarizes the result of a one year effort. During this period, we have: (1) extended the infinite dimensional, game theoretical control strategy to account for structured uncertainty arising in (A) the control influence operator associated with piezoceramic actuators, and (B) constitutive law evolution, and (2) performed a coupled fluid/structure/control analysis that synthesizes the distributed control approach derived in (1) with a flutter induced phenomenological, microcrack model for a panel. The work has also enabled the research team to: (1) develop an experimental wind-tunnel facility designed expressed for the study of the onset of flutter, nonlinear aeroelasticity and verification of the control theories (derived in this research), and (2) derive multiresolution-based analysis methods for the investigation of the onset of flutter in the experimental facilities.
