ACOSS Eleven (Active Control of Space Structures)
Abstract
The overall objective of the Simulation Extension Project is to identify and quantify those generic missing scenario and sensor parameters (as well as their interactions) which drive the performance of the space-based storing IR surveillance systems. The approach taken to achieve this overall objective has proceeded along two main avenues: Simulation Enhancements; and Simulation Applications. During the current reporting period, the Simulation Enhancements effort has concentrated in three areas: continuation of the Generic Scene Simulation development; enhancements to the Signal Processor Simulation; and expansion of the capabilities of the Integrated Large Space Structures Simulation. The Simulation Applications effort has been focused most recently on simulation and evaluation of algorithms for line-of-sight jitter reduction. Within the framework of the ROFT (Rapid Optics Fabrication Technology) program, the characterization of materials for large space mirrors is obtained by examining the impact of material properties on the performance of mirrors. The study recognizes major differences for material requirements between IR systems and laser applications. Research in active structural control encompasses design of reduced-order controllers for vibration suppression; development of approaches to system parameter identification; and generation of large-angle slew maneuvers. In this report, theoretical advances and demonstrations in the first two categories are presented. A scientific experiment to examine the process of synthesizing feedback controllers for precision pointing of a passive optical system in a wideband disturbance environment is continued.
