TECHNICAL ABSTRACT (LIMIT 200 WORDS)
To remain competitive, the US aerospace industry must continually improve system performance (e.g. increased adaptation and autonomy), enhance safety (e.g., fault tolerant systems), and reduce costs. These improvements demand avionics software that is orders of magnitude more complex than that used in current operational systems. While software complexity is increasing, there is a tremendous (and appropriate) pressure to ensure that new designs are safer to operate than the simpler systems they replace. In many cases (e.g., damage-adaptive control), methods that can improve vehicle performance are not used because verification and validation (V&V) tools that help ensure the complex system will not behave in an unexpected way are not available. The proposed research will lay the groundwork for such a tool by building on prior work by the authors in four unique areas: (1) the tool will work in the MATLAB/Simulink environment and will be easy to set up and operate, (2) the tool will be modular and allow easy integration of a variety of closed-form analysis methods, (3) the tool will aid in evaluating system performance as well as stability, and (4) the tool will assist in piloted simulation and flight test design.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
The proposed technology is relevant to the Global Civil Aviation goal and Enabling Technology requirements of the NASA Aero-Space Enterprise. NASA is keenly interested in pushing the envelope in the area of smart, adaptive, and intelligent aerospace vehicles; however, in many cases, the algorithms, methods, and software for such systems are ahead of our ability to verify and validate them. The proposed technology directly addresses this issue and will be essential if the Technology Readiness Level (TRL) of such systems is to be advanced.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
The initial market is the US Aerospace industry. As the industry moves to implement advanced control technologies in next generation vehicles, and to retrofit the existing military and commercial fleets to improve safety and performance, V&V tools that can pave the way to certification will become essential. Additionally, the flexible design of the proposed tool will allow it to have a broader appeal. The general performance evaluation framework for Simulink systems will appeal to a broad range of MATLAB users, making the algorithms developed under this effort appropriate for marketing as a general use MATLAB toolbox.
