In the case of large maneuvering flight in the full flight envelope, the flight parameters of the aircraft changed drastically, and the aircraft model presented a serious nonlinearity. The conventional control method can not guarantee good control effect throughout the flight envelope.This paper presents a A new fuzzy control method is proposed in this paper.The method integrates the optimization of fuzzy control functions and adaptive adjustment of fuzzy control system gain, which can greatly improve the quality and adaptability of the system.This method has been used in the design of integrated flight / thrust system. Simulation results show that the new fuzzy control method has achieved good control effect.
