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.
