Large, flexible space platforms, such as the proposed Space Station Freedom and Earth Observing System, may experience vibrations caused by astronauts, motorized instruments, or cooling systems which disturb sensitive pointing operations elsewhere on the platform. Linear control systems can be used to dampen these vibrations. In this paper, we discuss the application of optically implemented linear control algorithms to a truss structure model as NASA's Ames Research Center. We describe the system architecture and discuss the effect of reduced accuracy in linear control systems due to analog computation.
