Analytical and Ecperimental Modeling and Control of Flexible Structures

Abstract

This report summarizes seven major results. They are: (1) The modeling and experimental verification of closed loop slewing control of flexible structures which has resulted in a substantial improvement in pointing time. (2) The effects of slewing active structures (smart structures) have been modeled, experimentally verified and shown to result in an additional improvement in performance. (3) The nature of control structure interaction has been modeled and experimentally verified for vibration suppression in trusses and for frames using on-board electromagnetic actuators. (4) A Timoshenko model of layered piezoelectric devices has been developed. (5) A significant new model correction method has been developed for adjusting mathematical models based on experimentally obtained data. (6) A robust system identification has been developed and (7) a dynamic analysis and animation of flexible structures has been developed.
