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.
