Abstract

The Advanced Space Structures Technology Research Experiments (ASTREX) is a precision structure situated at the Phillips Laboratory Edwards Air Force Base, CA. The structure is a test bed to develop, test, and validate control strategies for large-angle three-axis slewing manoeuvres and vibration suppression. The ASTREX facility consists of the test article (with primary, secondary, and tertiary substructures along with mirrors). Rational fractional approach is used to obtain coprime equations in a multivariate setting. Parameterized compensators are obtained for regulation and stabilization. Simulation results are presented to show the accomplishment of vibration suppression
