UAV longitudinal and lateral stability and control characteristics identification are discussed. Offline methods based on Maximum Likelihood and quasi-Newton iteration and online method based on unscented Kalman filter are implemented and verified with aerodynamic data of ANCE. Identification results are compared with theoretic results to show the effectiveness of the methods.
