Abstract
Three recursive algorithms: the Recursive Least Squares (RLS), Kalman Filter (EKF) and Discrete Fourier Transform (DFT) are formulated. A comparative study has been carried out in the off-line environment using simulated and flight data for longitudinal and lateral-directional modes of aircraft motion. The results from the standard iterative Output Error Method (OEM) form the basis for evaluating the performance of these recursive methods. All the recursive methods discussed in this document gave results matching with those from OEM. The overall performance of DFT method was found to be better than the RLS and EKF methods and and it is computationally simple. The DFT technique seems to be preferable for online identification purposes
