Identifiability and estimation of aircraft parameters and delays by using optimal input design

This paper considers test of identifiability, optimal input design and estimation problem given by aerospace domain describing aircraft nonlinear dynamics with time delays. The original idea is to use an approximation well in line with the given system and an algebraic approach to analyze identifiability. Then the approximate model is considered to obtain the optimal input and to estimate the parameters and delays of the original model. Numerical results are given and compared.
