Modeling and Control of Flexible Vehicles in Space

Abstract

Several Aspects of modeling and control of large space structures have been investigated. A FORTRAN computer program is included which transforms modal data from commercially available finite element codes for personal computers to the forms needed for control system design. Design of a low order controller for a circular flat plate space structure is investigated by utilizing geometric symmetry of the structure and the control system actuators and sensor to decouple the system into smaller, single input -single output subsystems.
