Fuzzy logic control of wind tunnel temperature processes

The application of fuzzy logic controllers (FLC´s) to the control of nonlinear processes, typically controlled by a human operator, is a topic of much study. Recent application of a microprocessor based FLC to the control of temperature processes in a wind tunnel has proven to be very successful. The control of the wind tunnel temperature processes requires the ability to monitor temperature feedback from several points and to accommodate varying operating conditions in the wind tunnel. The FLC has an intuitive and easily configurable structure which incorporates the flexibility required to have such an ability. The design and implementation of the FLC is presented along with process data from the wind tunnel under automatic control
