Dynamic verification of large space structures
Abstract
The Marshall Space Flight Center developed a facility in which closed-loop control of large space structures (LSS) can be demonstrated and verified. The main objective of the facility is to verify LSS control system techniques so that on-orbit performance can be ensured. The facility consists of an LSS test article which is connected to a payload mounting system that provides control torque commands. It is attached to a base excitation system which simulates disturbances most likely to occur for orbiter and DOD payloads. A control computer contains the calibration software, the reference system, the alignment procedures, the telemetry software, and the control algorithms. The total system will be suspended in such a fashion that the LSS test article has the characteristics common to all LSS.
