| Abstract: | This paper reviews the motivation, concept and foundation of intelligent structures. The characteristics of intelligent materials as sensors and actuators in intelligent structures are introduced. The emphasis is put on the research and development status of piezoelectric materials and control methods in vibration control of beams, plates and shells. This paper also presents an overview of some respects of the application of intelligent structures in active vibration control, such as the method and criteria of optimal assignment of sensors and actuators, control spill over of flexible structures and its suppression methods. Finally, future research and development directions of vibration control of spacecraft structures are presented. |
