Student Profile
Practicing engineers and graduate students interested in learning the principles and applications of system identification and full-flight simulation for manned and unmanned aircraft and rotorcraft

About

Workshop Objectives

A. Review the fundamental methods of Manned and UAV aircraft and rotorcraft system identification methods using CIFER® and illustrate the benefits of their broad application throughout the flight vehicle development process

B. Review development of full-flight envelope air vehicle simulation using system identification point models and model stitching method using STITCH software and show flight-test examples

C. Provide the attendees with an intensive hands-on training of the CIFER® system identification and STITCH model stitching using flight test data and extensive Lab exercises. 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

Workshop Overview

Aircraft system identification is a highly versatile procedure for rapidly and efficiently extracting accurate dynamic models of an aircraft from the measured response to specific control inputs. Models might be desired to characterize the aircraft dynamics as a whole or to characterize an aircraft subsystem, such as an actuator, rotor system, or the engine. Key applications of aircraft system-identification results include piloted simulation models, comparison of wind-tunnel vs flight measurements, validation and improvement of physics-based simulation models, flight-control system development and validation, and handling-qualities specification compliance testing

The course and the CIFER® software use a frequency-response method that is especially well-suited to unstable aircraft and flight control system development. Model stitching is a technique that combines the individual identified models and trim data to produce a continuous full flight-envelope simulation of an aircraft or rotorcraft for flight control design and real-time simulation. This modeling approach is in the class of the quasi-linear parameter varying models (qLPV) and is shown in the course to accurately capture the nonlinear dynamics of the flight vehicle. The model stitching technique has been automated in a newly-developed software tool STITCH

Language of Instruction; Qualification of Participants

  The entire Workshop will be held in English. Participants must be able to communicate at a business level in English

Two Program Parts Over Three Days

   Part 1: Practical Methods for Aircraft and Rotorcraft System Identification and Hands-On Training

 ® using CIFER

Part 2: Full Flight Envelope Simulation by Stitching ID Point Models and Trim Data

Certificate

Participants who attend all sessions and participate in all simulations will receive an official certificate of completion from the continuing education and external studies division Technion

Student Profile

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

Study Format

  A three‐day workshop on 28-30/10/2018, Sunday thru Tuesday, 8:30-16:30
