Abstract: | In this paper we consider the problem of optimal regulation of large space structures in the presence of flexible appendages.
For simplicity of presentation, we consider a spacecraft consisting of a rigid bus and a flexible beam. The complete dynamics
of the system is given by a coupled set of ordinary and partial differential equations. We show that the solution of this
hybrid system is defined in a product space of appropriate finite- and infinite-dimensional spaces. We develop necessary conditions
for determining the control torque and forces for optimal regulation of attitude maneuvers of the satellite along with simultaneous
suppression of elastic vibrations of the flexible beam. |
