This thesis covers the development and simulation based implementation of a control law used to concurrently control the vibration and attitude of a square solar sail using dual gimballed corner-attached reflective vane actuators. An introduction to the topic is presented along with the prerequisite mathematical foundation needed to follow the thesis. Following that, a flexible structural dynamics model of the solar sail is developed using a Rayleigh-Ritz expansion to model the coupled rotational and elastic dynamics of the system. Next, a control law is developed using Lyapunov control design to concurrently damp structural vibrations as well as reorient the sail to a desired attitude. Subsequently, a control allocation process is presented to tackle the underconstrained nature of the tip vane actuators such that desired control forces can be realized as closely as possible. Finally, simulation results using the control law with the structural dynamics model are presented to demonstrate the improvement in vibration damping using the augmented PD control law developed as opposed to a simple PD control law.
