Abstract
New vibration control technology featuring integrated piezo actuators and
sensors can reduce and actively control undesired structural flexing and
vibrations. The objectives of this research are to design, implement, and test
active vibration controls consisting of integrated piezo actuators and sensors
on unmanned model aircraft. Finite element modeling was used to design
and analyze the composite structure prior to actuator integration. Piezo
actuators and strain gages were bonded to the structure and controlled
through integrated hardware and software to damp structural oscillation.
Combined with finite element analysis and computer simulation, the
resulting capability will allow prediction of sensor and actuator locat
