Sizing of active piezoelectric struts for vibration suppression on a space-based interferometerThe present paper concerns itself with the active suppression of mechanical vibrations on a representative future spaceborne optical interferometer. This is accomplished by the incorporation of a set of piezoelectric struts into the truss structure of the interferometer and the use of these active struts to modify the damping and stiffness characteristics of the truss. It is shown that vibration propagation can be significantly reduced through the use of very simple control laws. It is further shown that the force and stroke requirements for the active struts for this application are rather modest and fall well within the capabilities already demonstrated by prototype hardware in ground testing.
