Paper Abstract

Composite booms are an emerging low weight structural alternative for on-orbit satellites. With any satellite, vibrational control of the structure is a concern. Using traditional measurement techniques, possible inaccuracies may result due to the lightweight natures of the composite boom. Laser vibrometry techniques are investigated in this paper as an alternative to standard accelerometer measurements. The advantages of non contact measurement are presented in two different experimental setups. Using the dynamic measurements obtained from these experiments, a positive feedback controller is developed to attenuate the vibration of the strut.
