Application of Artificial Bee Colony Algorithms for Unsteady Aerodynamic Parameter Estimation

When the aircraft is in the state of the high angle of attack, the aerodynamic characteristics of the aircraft are rendered as non-linear and unsteady, therefore the aerodynamic model and the parameters in the model face higher requirements. To deal with the nonlinear and unsteady in the state of high angle of attack, this paper uses the artificial bee colony (ABC) algorithm in the aerodynamic parameter estimation to replace the commonly used gradient algorithms. The simulation results show that ABC algorithm is an effective method in identifying the aerodynamic parameters in the high angle of attack.
