Integrating Information Architecture and Material Architecture in Structural System Design

Back
Abstract:
Information Architecture (IA) deals with the distribution of sensing and actuating resources (precisions, locations) throughout system. Material Architecture (MA) deals with the distribution of massive material to form the structure. The goals are to use the smallest control energy to control the structure, while simultaneously using the smallest amount of material to build the structure. Results so far are global in three special cases: 1) In the presence of only compressive loads and no controls, the optimal MA is found for the fully nonlinear structure; 2) In the presence of only bending loads and no controls, the optimal MA is found for the fully nonlinear structure; 3) In the presence of a given linear dynamic structure, with zero-mean white noise sources in all sensors and actuators, an algorithm is given for the IA problem. An ad hoc example is given combining these three individually-global results 1)-3), but their combination is still research and not global.

Biographical Sketch:
Robert E. Skelton is the Daniel L. Alspach Professor of Dynamic Systems and Control at the UCSD Jacobs School of Engineering. He joined UC San Diego in 1996, after serving as a professor of aeronautics and astronautics at Purdue University from 1975-1996. Skelton began his career at the Marshall Space Flight Center, working first with Lockheed Missiles and Space Company and then Sperry Rand for 12 years. He has been involved with spacecraft control (SKLAB and Hubble Space Telescope) for many years and has served on the National Research Council's Aeronautics and Engineering Board. Skelton is a Fellow of AIAA and IEEE, and has published three books and more than 100 journal papers.
