The objectives of this course are to: (1) review the fundamental methods of Manned and UAV aircraft and rotorcraft system identification methods with Hands-on Training using CIFER® and illustrate the benefits of their broad application throughout the flight vehicle development process; (2) provide the attendees with an intensive hands-on training of the CIFER®system identification, using flight test data and 10 extensive Lab exercises. Students will work on comprehensive laboratory assignments using student version of software provided to course participants (requires student to bring a laptop). The many examples from recent manned and UAV aircraft programs illustrate the effectiveness of this technology for rapidly solving difficult integration problems. The course will review key methods and computational tools, but will not be overly mathematical in content. 

Key Topics

  • Overview of system identification methods and applications
  • Flight testing and instrumentation for handling-qualities and manned/unmanned control system development
  • Simulation model fidelity analysis and design model extraction from prototype flight testing
  • System ID of manned and UAV aircraft dynamics and control from flight test data
  • Model stitching to build accurate full flight envelope nonlinear model from system ID point models
  • Hands-on training in system identification training using CIFER®
  • Over the two-day course students work ten comprehensive labs on model identification and verification using flight test data 

Who Should Attend

The course is intended for practicing engineers and graduate students interested in learning the principles and applications of system identification for manned and unmanned aircraft and rotorcraft.  The course assumes some basic knowledge of the concepts of: dynamics, frequency-responses, transfer functions, and state-space representations. The course is not highly mathematical and no experience with other tools is a prerequisite.


Dr. Mark Tischler is a Senior Technologist and Flight Control Technology group leader with the U.S. Army Aviation Development Directorate at Moffett Field, CA. Tischler headed the development of widely-used tools for dynamics and control analysis and has been involved in numerous flight-test projects. He has published widely in this field and is the author of Aircraft and Rotorcraft System Identification: Engineering Methods With Flight Test Examples, 2nd Edition (AIAA 2012), Practical Methods for Aircraft and Rotorcraft Flight Control Design: An Optimization-Based Approach (AIAA 2017), and Advances in Aircraft Flight Control (Ed) (AIAA and Taylor & Francis, 1996).

    Course Materials

    Course notes will be made available about one week prior to the course event. You will receive an email with detailed instructions on how to access your course notes. Since these notes will not be distributed on site, AIAA and your course instructor highly recommend that you bring your computer with the course notes already downloaded. Aircraft and Rotorcraft System Identification: Engineering Methods With Flight Test Examples, 2nd Edition (M.B. Tischler with R.K. Remple) will be provided as part of course registration.

    Course Registration

    • Registration will open in September 2018.
