Abstract:

This report summarizes the research and developement results of the SBIR Phase I study entitled Hierarchical Damage Tolerant Controllers for Smart Structures supported by U.S. Air Force under Contract No. F33615-88-C-3212. The major aim of this study is the investigation and definition of a baseline architecture for a smart aerospace structure which can detect and isolate structural damage in real-time and provide on-line reconfiguration of the structures control system under the detected impairment conditions. In particular, we investigate how a smart aerospace structure can be implemented as a real-time knowledge based expert system by addressing issues involved with structural knowledge representation, structural damage detection and isolation strategies and real-time performance in an embedded environment.
