The longitudinal attitude control of a type of Tail-sitter UAV is studied in this paper. In order to solve the singular problem of pitch angle during the tilting process of fuselage, the double Euler angle algorithm is used for modeling. Fuzzy self-tuning PID control method and L1 adaptive control method are used to design the longitudinal attitude controller respectively to counteract the susceptibility to disturbance during the flight, especially in tilting process. The numerical simulation is carried out through MATLAB, and the simulation results show that: This controller can overcome the model parameter changes and other uncertain disturbances to the Tail-sitter UAV during the flight
