The L1 adaptive control technology developed by Naira Hovakimyan is being widely applied across various industries, including ones involved with aerospace, electrical, biomedical, and mechanical engineering. In a recent flight test program at NASA, the L1 adaptive controller was used in stall and post-stall flight of a subscale commercial jet in the presence of various adverse conditions, and it enabled modeling of nonlinear aerodynamics at stall and in post-stall flight. It expanded the flight envelope up to 28 degrees in angle of attack. L1 adaptive control has also been implemented and flight-tested in several Unmanned Aerial Vehicles (UAVs) for time-critical missions, like intelligent surveillance and reconnaissance (ISR). L1 adaptive control has also been used for drilling applications in oil production, control of anesthesia, fiberoptics, and disk drive control.
