About the Seminar:
Aircraft system identification involves the determination of dynamic models from measured flight test data.  These models range from stability and control derivatives, to global aerodynamic models, to low-order equivalent systems models, to sensor biases and time delays, to real-time gain and phase margins, and others.  As a result, system identification analyses are highly useful in updating nonlinear simulations for control design, pilot training, mission rehearsal, envelope expansion, and others.  Recently, the AIAA Journal of Aircraft published a special issue in which authors summarized advances in aircraft system identification made at their institutions over the last 20 years.  This talk presents some of those advances made at the NASA Langley Research Center.  Examples include X-planes, hypersonic and launch / re-entry vehicles, aeroelastic aircraft and wind tunnel test articles, and subscale demonstrators.

About the Speaker:
Dr. Jared Grauer is a research engineer at NASA Langley Research Center in the Dynamic Systems & Control branch.  His work there focuses on improving aircraft system identification and feedback control methods to better support NASA missions and strategic research goals.  He is an associate fellow of the AIAA, incoming chair of the AIAA Atmospheric Flight Mechanics technical committee, board member of the ACGSC, and author of over 100 technical publications.  He holds B.S., M.S., and PhD degrees from the University of Maryland, where he is also a lecturer for courses related to aircraft dynamics and control.
