    Course Overview

    Aircraft System Identification – Theory and Practice


    This course teaches the theory and practice of building mathematical models for aircraft dynamics based on measured flight data, also called aircraft system identification. Results are useful for flight simulation, comparisons with CFD and wind tunnel results, flight envelope expansion, control system design, and flying qualities analysis, among many other uses. The course includes relevant theory and background, but focuses mainly on practical approaches and solutions. All aspects of aircraft system identification are included — design of the experiment, instrumentation, data handling, formulating the model, estimating model parameters, and model validation techniques. A textbook and accompanying MATLAB® software toolbox is available for purchase to each student. The software includes a wide variety of tools used at NASA Langley for aircraft system identification problems. The course also includes practical hands-on experience, to allow students to become familiar with the use of the software on real flight data and to properly interpret results.

    Key Topics:

    • Background and introduction
    • Mathematical models for aircraft
    • Modeling in the time and frequency domains
    • Experiment design, instrumentation, and data handling
    • System IDentification Programs for AirCraft (SIDPAC) - MATLAB® Software
    • Hands-on practical experience

    Who Should Attend:

    This course will be useful to flight test engineers, simulation engineers, control system designers, aircraft designers, applied aerodynamicists, flying qualities engineers, engineering managers, and anyone who needs to identify high fidelity mathematical models based on measured data from an experiment, or understand how it is done.
