Abstract :
This paper introduces design of flight control system based on QFT theory. Combined non-linear dynamic inversion method with singular perturbation theory, the pseudo linear Super-maneuverable flight model is established. Aiming at the uncertain factors in non-linear dynamic modeling and definituding the range of uncertain factors and system performance requirements, the mathematical model of non-linear dynamic inversion flight control system based on QFT is set up and the simulation curves are produced. The simulating curves show that system has robustness stability and system design is feasible.
