Abstract

The independent structural design for stochastically disturbed activestructures, as part of the integrated structure/control design methodology, is the subjectof this paper. The methodology requires the consideration of a generic controller in or- der to guarantee the performances of the active structure resulting from the mechanicaldesign.An elastic 20 m long Extendable and Retractable Mast fitted with piezoelectric local ac- tuators and an offset rigid antenna illustrates the method.Configurations, values of modal dampings are investigated using modal analysis, analy- sis of disturbance and actuator effects, inclusion of modal shapes, choice of actuatorsand sensors, determination of final performances.
