Abstract

This paper presents a strategy for active damping of cable structures. The control algorithm has guaranteed stability, including at the parametric resonance. The paper also describes an efficient modelling technique for cable structures; simple and powerful results are established, which allow to predict the closed loop poles with a root locus technique. 1. Introduction The current design of the space station is largely based on trusses, but it is quite likely that the future large space structures (LSS) will use large trusses connected by tension cables, to increase their global stiffness, in a way similar to that used to stiffen the airplanes in the early days of aeronautics. This concept of tension truss structure has alread
