Abstract

This paper presents experimental results relating to the Air Force Research Laboratory Precision Deployable Optics System (PDOS) ground demonstration. The PDOS experiment represents a sub-scale experimental test-bed for the demonstration of science and technology related to a large-aperture deployable space-based telescope systems. A description of the experimental test-bed is included. A description of microdynamic phenomena, referred to as `events' or `microlurches', observed during the test phase of the ground demonstration is presented. The performance of a three input, three output, high bandwidth structural controller operating in the presence of these events is presented and compared to the performance of the uncontrolled system.
