Fuzzy control allocating and fuzzy gain scheduling for transitional mode control of CRW aircraft

The steady transition between the helicopter mode and the fixed-wing mode is the key technology of Canard Rotor/Wing aircraft. To solve the problems of control input transfer and nonlinearities in the transitional flight mode, a synthesized control method based on fuzzy membership synthesized the fuzzy gain scheduling and fuzzy control allocating was proposed, and during transitional flight process, the method can not only guarantee the stabilities of pitch attitude and flight path altitude effectively, but also avoid state jitters due to conventional gain scheduling and control input directly switching. Simulation result shows that the method proposed can both ensure the aircraft transiting steadily and avoid the state jitters.
