Abstract：To solve the problem of maneuver control for fighters at high angle-of-attack (AOA), the model reference dynamic inversion (MRDI) control law was designed, based on the nonlinear dynamic inversion controllers utilizing angular rates as commands, ideal reference models representing the desired flying qualities and proportional-plus-integral compensators. Both the expected type of vehicle response and the control of maneuver at high AOA were approached by this method. The tuning of controller parameters, the rating of the airplane performance and the evaluation of close-loop system flying qualities were completed by simulation and the mission-oriented flying qualities (MOFQ) method which could be considered as a feasible assessment method for flying qualities at high angle-of-attack and it pointed out the demands for flying qualities created by special missions. The MRDI control law and the MOFQ method can be referenced by fighter control law design and flying qualities evaluation.
