Fuzzy logic controller optimization design for tiltrotor aircraft landing conversion

The tiltrotor aircraft can flight in the helicopter mode or in airplane mode during the procedure of its landing conversion. Its control system is very complicated and it is very difficult to obtain the model. After studying the mathematic model of the tiltrotor aircraft, we introduce the fuzzy logic control and design the flight controller based on fuzzy logic. The fuzzy logic controller is optimized in Genetic Algorithm. The simulation shows that the whole control system of the tiltrotor aircraft poses the good performances. The controller meets the requirement about its landing character. It is very useful to design the flight control system in the Fuzzy logic control via GA.
