DEMAND for UNMANNED® presents: Aircraft and Rotorcraft System Identification Engineering Methods for UAV Applications

System identification methods are ideally suited for rapidly determining bare-airframe simulation models of fixed-wing and rotorcraft UAVs, since UAV configurations change widely throughout their development process. Also the parameters needed for a physics-based model are often poorly known for UAVs, or the modeling assumptions do to correspond well to the physical characteristics of modern UAV configurations. A full-flight envelope UAV simulation can be obtained from “stitching” together only a few point identification models, obtained from a very limited flight-testing program. This webinar will review the fundamentals of the frequency-response method for UAV aircraft and rotorcraft system identification. Special methods are needed for modern multi-copter or eVTOL configurations with highly redundant controls. Identifications methods and results are illustrated with many recent UAV examples. Particular emphasis is given to the important role of system identification in UAV flight control development, implementation verification, and documentation of performance. The course will review key methods, computational tools, and complimentary reference material. The lecture material will be followed by a question and answer period.
