TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Impact Technologies, in collaboration with Tennessee State University, propose to develop and demonstrate an adaptive system identification and multi-loop control methodology that provides real-time aircraft structural mode suppression associated with aeroservoelastic interaction under upset and damage conditions. The proposed program will develop an effective real-time aircraft structural model, including rigid body dynamics and structural flexible modes, which will be used by the on-line, adaptive control system proposed. In parallel, the research team will also develop an innovative time/frequency domain system identification algorithm that can provide continuous updates to the real-time aircraft model and automatically assess the level of existing structural mode excitation. Next, a singular value decomposition technique will be implemented to capture and quantify the associated dominant parameter uncertainties of the dynamic aircraft model and adjust accordingly. Finally, a multi-loop adaptive control structure will be developed that provides both structure and robustness of the aircraft by using the continuously identified model with the overall goal of responding to the structural safety and performance needs including the effects of aeroservoelastic interaction and structural flexible mode changes. The proposed approach uses a generalized predictive control (GPC) scheme, which can be used to both update the real-time model and design a controller, for active aeroservoelastic suppression under upset conditions.
POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The successful completion of the proposed work will substantially improve the performance, reliability, and survivability of the general aviation (GA) aircraft. Potential applications of the software include design and testing of Integrated Resilient Aircraft Control (IRAC), aircraft IVHM, Crew Exploration Vehicle, Reusable Launch Vehicles, Unmanned Air Vehicles and future generation general aviation platforms.
POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The potential commercial use of the developed technologies is broad. Examples of key customers that could benefit through use of the developed technologies include: JSF, military and commercial fixed-wing aircraft, rotorcraft, and high-performance land vehicles.
TECHNOLOGY TAXONOMY MAPPING (NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.)
