Abstract
Experimental results obtained in a multiyear program to assess the cost and benefits tradeoffs of active structural control for precision space structures are reported. The combination of a complex segmented optics structural test article with broadband disturbances and very stringent performance requirements on both line-of-sight and higher-order aberration errors resulted in an exceptionally challenging control task, involving over 20-dB attenuation of dozens of vibration modes within the 10-200-Hz disturbance band. The authors applied a variety of control design techniques together with two distinct suites of vibration control actuator hardware. The control challenge, the actuator hardware designs, and the remarkably successful experimental results pertaining to a baseline decentralized control design are described.
