Development of a two step self-triggered adapting wind tunnel control system

In this paper, a systematic approach is presented and a physical experiment substantiated for a SISO wind tunnel adaptive control system. This approach includes a two-step adaptation scheme: The first comprises a triggered system identification process and the second an adapting controller system. To verify this integrated systems engineering approach, a physical wind tunnel was constructed with an axial fan and airspeed sensors. A real-time adapting system model, coupled with an adaptive control system is interfaced with the wind tunnel. The real-time data from the system in operation is analyzed and used to influence how the controller adapts through system identification techniques as well as PID tuning criteria.
