Study on the Application Scheme of Aerodynamic Coefficient Identification Based on the Differential Evolution Algorithm

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 differenti...
