An integrated flight control system is designed according to the six DOF nonlinear model of pitching channel of hypersonic vehicle X-43A. The system is composed of one fuzzy controller and two PD controllers. Based on genetic algorithm, the optimization process of fuzzy control rules and PD feedback parameters is carried out automatically without experts’ knowledge and training data in advance. Simulations show that the method is able to satisfy both the robustness of flight control system and the convergence of optimization process on request, especially obtaining superior robustness than classical flight control system, which is designed under the same optimization tool and basic control strategies.
