Abstract

"This effort will investigate a blending of Optimally Distributed Sensing and Actuation (ODAS) with Adaptive Filtering and Disturbance Feed-forward (AFDF) techniques with promise for simultaneously mitigating the impacts of Directed Energy (DE) systempayloads on aircraft while improving the Acquisition, Tracking, and Pointing (ATP) performance of DE systems. The innovation is the integration and application of research in ODSA techniques with AFDF to coupled aircraft-flexible beam train applications.The ODSA techniques provide: 1) Sensor-actuator suite to measure and mitigate disturbances to the aircraft arising from the DE system; 2) Disturbance signal representing the structural/acoustic modes disturbing the forward path of the ATP system;3)Similarly derived sensor set/signal representing those structural/acoustic modes disturbing the ATP feedback path. These signals are coherent with the beam control jitter induced by the respective modes and represent the dominate contributions of thesemodes. Thus they are ideal for use with AFDF to simultaneously control and mitigate vibration/acoustic induced effects on the coupled aircraft-DE system. The commercial potential for the Optimally Distributed Sensing and Actuation (ODAS) system and Adaptive Filtering and Disturbance Feed-forward (AFDF) techniques developed in this effort are significant, due to their broad applicability to many industries(e.g. automotive, semi-conductor, medical, etc.). Initially, CSA will focus on a transition to ABL. CSA is currently supporting Lockheed-Martin on the development of the integrated beam control system for ABL. This provides a transition path to the ABLprogram from a successful STTR effort. CSA also supports a number of other DoD, NASA , and commercial customers in the development of aerospace stabilization systems. Since CSA is an established provider of these solutions, insertion of the higherperformance OSDA-AFDF algorithms represents a significant opportunity. CSA has broadened its customer base, recently completing projects in the automotive a
