Abstract: Aiming at the characteristics of nonlinear coupling of the rigid body 6 DOF model of UCAV, an adaptive fuzzy PID attitude control method is designed combining with specialistic experience. The nonlinear model of UCAV is linearized with the principle of small disturbance, thus the state space expressions of longitudinal and lateral channels are obtained and the decoupling of the longitudinal and lateral channels is achieved. To verify the designed adaptive fuzzy PID controller, the simulation is carried out aiming at the pitch angle and velocity of the longitudinal channel and the roll angle of the lateral channel. The result shows that the designed controller has faster responsive speed and higher stability, and it can control the UCAV to achieve the desired attitude effectively.
