Abstract:

This report covers active structural control theory extensions, simulations, and demonstration test planning as they relate to precision control of large space systems. Theory material includes a filter accommodation technique for stabilizing higher modes without degrading controlled mode performance, Liapunov stability analysis, and disturbance accommodation techniques for systems where damping along cannot meet requirements.
