A large space-based interferometer (FMI) is used as a testbed for ideas de veloped in the NASA Controls and Structures Interaction (CSI) program. An end-to-end simulation of the optical performance of the system has been developed and used to dem onstrate impedance-based adaptive structural control and control of thermal disturbances. Other issues briefly addressed include integrated optical/structural modeling and a hier archical, layered control strategy.
