The topic of vibration control of large space structures which, in this instance are modeled by equivalent continua, is addressed here. A 'singular (or fundamental) solution' approach is utilized and the control algorithm is based on a fully coupled nodal system of equations which permits the effects of non-proportional damping to be monitored. Additionally, the structure will be allowed to undergo large deformations which will necessitate the implementation of a nonlinear control algorithm. In the scheme proposed here, the calculation of the feedback control forces will be based on the feedback gain matrix obtained from a solution of the linear optimal control problem. Examples will be presented to illustrate the controllability of the vibrations in both the linear and nonlinear cases.
