Abstract

This document summarizes the process of identifying unknown dynamic systems from measured flight test data. Several available system identification tools were evaluated based on accuracy and robustness. Among them,SIDPAC developed by NASA was chosen. The objective of this study is to lay out the procedures to identify unknown systems from flight test data and to provide recommendations for following flight tests. Data from the Fenrir’s flight was used.
