【Abstract】 A Method of dynamic system identification based on genetic algorithms is put forward through combining genetic algorithm with maximum likelihood method, and nonlinear aerodynamic parameter identification of missile using simulation data is carried out to verify the validity and feasibility of the formed method. The identification results are satisfactory, which shows the maximum likelihood method based genetic algorithm is effective for dynamic system identification.更多还原
