To achieve satisfactory pitch maneuverability under post-stall flight conditions with high angle of attack,standards for pitch agility evaluation are presented and a corresponding control allocation design is carried out in this paper.Firstly,a mathematical fighter model with multiple control actuators is introduced and the pitch control performances of the canards,the elevons and the thrust vectoring are compared for post-stall maneuvers.Subsequently,to obtain the maximal achievable trimmed angle of attack and realize a satisfied angle of attack tracking performance,a control allocation design with the canards,the inner elevons and the thrust vectoring is designed.Then a hybrid parameter optimization method which combines Nelder-Mead method and penalty function method is used to optimize the controller parameters.Finally,the simulation results show that remarkable post-stall pitch agility is achieved with the control allocation and parameter optimization design adopted in this paper.
