Abstract EN
The present paper studies the application schemes of aerodynamic coefficient identification based on the differential evolution (DE) algorithm from free flight data.
Two identification schemes utilizing the DE algorithm are proposed, including the whole discrete point (WDP) scheme and the differential interval linear (DIL) scheme.
Several comparative tests are conducted to study the performances of the two schemes by using the noisy simulated flight data and the measured radar data.
The results show satisfactory performance in estimating the aerodynamic coefficients for the two schemes.
The WDP scheme provides more accurate and robust coefficients estimates in exchange of more than two times greater computational effort compared with the DIL scheme.
