A Mathematical Model Based Control System for Wind Tunnels

ABSTRACT: The objective of the Phase II effort is to extend the mathematical model investigated in the Phase I to include wind speed as well as temperature modeling, continue its development for a University of Notre Dame Wind Tunnel Facility, and demonstrate utility by adopting the model to a government facility specified by AFOSR. Specifically, the Phase II will include developmental work in making measurements, development of the mathematical model, neural network methods for organizing databases of facility performance, error-management methods, and demonstration of control for both fast and slow processes such as wind tunnel speed and temperature, respectively. BENEFIT: The result of this STTR program will allow improved control and utilization of wind tunnel facilities. The program also offers information that can improve the safety of operating wind tunnel facilities. Finally, for large scale facilities, this program may reduce staffing requirements and thereby costs.
