Direct adaptive disturbance rejection and control for a deployable space telescope, theory and application

Discrete time direct adaptive control with disturbance rejection is derived using the command tracker generator (CGT) design. A proof of stability for this controller is provided and the special case of adaptive disturbance rejection using a fixed gain controller is considered Preliminary results of the simplified adaptive controller performance on the Deployable Optical Telescope (DOT) prove promising, but overall reduction of observed motion in the multi-input, multi-output system is not easily achieved.
