Abstract
A control technology is one of the important points to be developed for Large Space Structures(LSS) such as space stations which are characterized by being large and lightweight and having lower structural vibration frequency. This report describes a control technology to increase the structural damping of LSS actively. A control system, Direct Velocity Feedback(DVFB), is used to reinforce the damping of the mechanical system. The stability of the closed-loop system when a proof mass actuator(PMA) is used for this purpose was examined. Then, it was shown that the stability of DVFB that has been suggested so far cannot be proved if the influence of dynamic characteristics of PMA is taken into account, and new stable conditions were obtained. Next, vibration damping tests of cantilever rigid frame structures were carried out using pivot type PMA models. Through the tests on the 1 input-1 output system and the 2 input-2 output system, favorable vibration controllability was demonstrated. Furthermore, sizing of PMA was studied. 16 refs., 24 figs., 2 tabs.
