Aerodynamic parameter identification technology is an important method to get the aerodynamic parameter of flight vehicles. The mathematical models of flight vehicles are generally nonlinear form. In order to remove the model error caused by linearization, the output-error method has been adopted to identify the aerodynamic parameters in the longitudinal nonlinear model of an UAV (unmanned aerial vehicle) in this paper. Longitudinal nonlinear state and output equations of the UAV are established. Then simulation data of longitudinal nonlinear model with measurement noise is used to verify this method. The results show that the unknown aerodynamic parameters in the nonlinear model can be effectively identified by this method.
