Abstract
A design for the active structural control of a two-element laser beam expander is described. The lengths of selected struts of a trussed, quadrapod graphite/epoxy structure are monitored and controlled by sensor/actuators using a modal control technique with rate-damping enhancement. The details of structural design, optical arrangement, strut sensors and actuators, and control algorithms are discussed.
